Time to Check Your AC Systems

March 27, 2019 by spihomei

It is heating up out here in Arizona (finally) – even here in Prescott, but especially in the Phoenix area. Now is the time to make sure your air conditioning is ready to handle the heat!  As part of a home inspection (in the Phoenix and Prescott areas) we do take a close look at the HVAC units, and if in doubt we will suggest an HVAC company come take a closer look. We also have routine maintenance done on our own home’s unit since a building’s central air-conditioning system must be periodically inspected and maintained in order to function properly. While an annual inspection performed by a trained professional is recommended, homeowners can do a lot of the work themselves by following the tips offered in this guide.Exterior Condenser Unit

Clean the Exterior Condenser Unit and Components
The exterior condenser unit is the large box located on the side of the building that is designed to push heat from the inside of the building to the outdoors. Inside of the box are coils of pipe that are surrounded by thousands of thin metal “fins” that allow the coils more surface area to exchange heat. Follow these tips when cleaning the exterior condenser unit and its inner components — after turning off power to the unit!
  • Remove any leaves, spider webs and other debris from the unit’s exterior. Trim foliage back several feet from the unit to ensure proper air flow.
  • Remove the cover grille to clean any debris from the unit’s interior. A garden hose can be helpful for this task.
  • Straighten any bent fins with a tool called a fin comb.
  • Add lubricating oil to the motor. Check your owner’s manual for specific instructions.
  • Clean the evaporator coil and condenser coil at least once a year.  When they collect dirt, they may not function properly.
Inspect the Condensate Drain Line
Condensate drain lines collect condensed water and drain it away from the unit.  They are located on the side of the inside fan unit. Sometimes there are two drain lines—a primary drain line that’s built into the unit, and a secondary drain line that can drain if the first line becomes blocked. Homeowners can inspect the drain line by using the following tips, which take very little time and require no specialized tools:
  • Inspect the drain line for obstructions, such as algae and debris. If the line becomes blocked, water will back up into the drain pan and overflow, potentially causing a safety hazard or water damage to your home.
  • Make sure the hoses are secured and fit properly.
Clean the Air Filter
The air filter slides out for easy replacement
Air filters remove pollen, dust and other particles that would otherwise circulate indoors. Most filters are typically rectangular in shape and about 20 inches by 16 inches, and about 1 inch thick. They slide into the main ductwork near the inside fan unit. The filter should be periodically washed or replaced, depending on the manufacturer’s instructions. A dirty air filter will not only degrade indoor air quality, but it will also strain the motor to work harder to move air through it, increasing energy costs and reducing energy efficiency. The filter should be replaced monthly during heavy use during the cooling seasons. You may need to change the filter more often if the air conditioner is in constant use, if building occupants have respiratory problems,if  you have pets with fur, or if dusty conditions are present.
 
Cover the Exterior Unit

When the cooling season is over, you should cover the exterior condenser unit in preparation for winter. If it isn’t being used, why expose it to the elements? This measure will prevent ice, leaves and dirt from entering the unit, which can harm components and require additional maintenance in the spring. A cover can be purchased, or you can make one yourself by taping together plastic trash bags. Be sure to turn the unit off before covering it.

Close the Air-Distribution Registers
Air-distribution registers are duct openings in ceilings, walls and floors where cold air enters the room. They should be closed after the cooling season ends in order to keep warm air from back-flowing out of the room during the warming season. Pests and dust will also be unable to enter the ducts during the winter if the registers are closed. These vents typically can be opened or closed with an adjacent lever or wheel.  Remember to open the registers in the spring before the cooling season starts.  Also, make sure they are not blocked by drapes, carpeting or furniture.
In addition, homeowners should practice the following strategies in order to keep their central air conditioning systems running properly:
  • Have the air-conditioning system inspected by a professional each year before the start of the cooling season.
  • Reduce stress on the air conditioning system by enhancing your home’s energy efficiency. Switch from incandescent lights to compact fluorescents, for instance, which produce less heat.
In summary, any homeowner can perform periodic inspections and maintenance to their home’s central air-conditioning system.

Defrost Cycle of a Heat Pump

February 8, 2019 by spihomei

Baby, it’s cold outside! So today’s blog from your hometown Home Inspector is all about heat pumps. Whether you are in the Phoenix area, or in Prescott and quad cities area, learning how your heat pump operates may help you. Here, we cover some fundamentals of a particular heating system called a heat pump using non-invasive, visual-only inspection techniques. We also discuss its defrost cycle.  Yes, more than you may want to know, but… here you go. As always, feel free to contact me with any of your home inspection questions.

How it Operates
When a heat pump is operating in the heating mode or heat cycle, the outdoor air is relatively cool and the outdoor coil acts as an evaporator.  Under certain conditions of temperature and relative humidity, frost might form on the surface of the outdoor coil.  The layer of frost will interfere with the operation of the heat pump by making the pump work harder and, therefore, inefficiently.  The frost must be removed.  A heat pump has a cycle called a defrost cycle, which removes the frost from the outdoor coil.
A heat pump unit will defrost regularly when frost conditions occur.  The defrost cycle should be long enough to melt the ice, and short enough to be energy-efficient.
In the defrost cycle, the heat pump is automatically operated in reverse, for a moment, in the cooling cycle.  This action temporarily warms up the outdoor coil and melts the frost from the coil.  In this defrost cycle, the outdoor fan is prevented from turning on when the heat pump switches over, and the temperature rise of the outdoor coil is accelerated and increased.
The heat pump will operate in the defrost cycle until the outdoor coil temperature reaches around 57° F.  The time it takes to melt and remove accumulated frost from an outdoor coil will vary, depending on the amount of frost and the internal timing device of the system.
Interior Heating Element
During this defrost cycle with older heat pumps, the indoor unit might be operating with the fan blowing cool air.  To prevent cool air from being produced and distributed inside the house, an electric heating element can be installed and engaged at the same time as the defrost cycle.  In defrost mode, this heating element will automatically turn on, or the interior blower fan will turn off.  The heating component is wired up to the second stage of a two-stage thermostat.
The Typical Cycle
The components that make up the defrost cycle system includes a thermostat, timer and a relay.  There is a special thermostat or sensor of the defrost cycle system, often referred to as the frost thermostat.  It is located on the bottom of the outdoor coil where it can detect the temperature of the coil.
When the outdoor coil temperature drops to around 32° F, the thermostat closes the circuit and makes the system respond.  This causes an internal timer to start.  Many heat pumps have a generic timer that energizes the defrost relays at certain intervals of time. Some generic timers will energize the defrost cycle every 30, 60 and 90 minutes.
The defrost relays turn on the compressor, switch the reversing valve of the heat pump, turn on the interior electric heating element, and stop the fan at the outdoor coil from spinning.  The unit is now in the defrost cycle.
The unit remains in the defrost cycle (or cooling cycle) until the thermostat on the bottom of the outdoor coil senses that the outdoor coil temperature has reached about 57° F. At that temperature, the outdoor coil should be free of frost.  The frost thermostat opens the circuit, stops the timer, then the defrost cycle stops, the internal heater turns off, the valve reverses, and the unit returns to the heating cycle. A typical defrost cycle might run from 30 seconds to a few minutes.  The defrost cycles should repeat regularly at timed intervals.  An inspector should not observe a rapid cycling of the defrost operation.
In summary, certain conditions can force a heat pump into a defrost cycle (or cooling cycle) where the fan in the outdoor coil is stopped, the indoor fan is stopped or electric heat is turned on, the frost melts and is removed from the outdoor coils.  When the frost thermostat is satisfied or a certain pre-set time period elapses, the outdoor fan comes back on, and the heat pump goes back into the heating cycle.
One problem of many older heat pump systems is that the unit will operate in the defrost cycle regardless of whether ice is present.  On these systems, if it’s cold outside, the defrost cycle might turn on when it is not needed.
If the defrost cycle is not functioning properly, the outdoor coil will appear like a big block of ice, making the unit non-functional.  Damage could result if the heat pump operates without a functional, normal-operating defrost cycle.
Causes of Frost
There are many reasons why an inspector might find frost and ice stuck on an outdoor coil of a heat pump that is not properly defrosting.
The cause of the frost and ice problem may include:
  • a bad reversing valve;
  • a damaged outdoor coil;
  • a wiring problem;
  • a bad thermostat;
  • a leak in the refrigerant;
  • a dirty outdoor coil covered with grass, dirt, debris and/or pet hair;
  • a fan that won’t turn on;
  • a fan installed backwards with the blades running in the wrong direction;
  • a motor operating in the incorrect direction; and/or
  • a replacement fan motor spinning at a very low rpm.
Diagnosing apparent problems with the defrost cycle of a heat pump is beyond the scope of a home inspection.

Home Inspection – Ceiling Fans

June 4, 2018 by spihomei

Most of the homes I inspect in Arizona have ceiling fans, and properly installed and maintained ceiling fans can inexpensively cool or warm building occupants.  Like other fans, it is used to provide comfort for building occupants by circulating air within a room.

Fun Facts About Ceiling FansMost household ceiling fans have four or five blades.

  • An adult human cannot be decapitated by a ceiling fan, according to the TV show “MythBusters.”  A powerful, industrial-strength fan might be able to damage a skull or slice a person’s neck, however – so don’t test this myth (just in case – ha).
  • Ceiling fans were first used in the United States in the 1860s. They were powered by a system of belts driven by a stream of running water.
  • Unlike air conditioners, fans do not actually cool the air, which is why they merely waste electricity when they circulate air in an unoccupied room (yes, I am guilty of this sometimes).

Ceiling Fan Components

A ceiling fan is comprised of the following parts:

  • electric motor:  varies with the size of the fan and its application;
  • blades:  typically, two to six spinning, precision-weighted blades made from metal, wood or plastic; industrial fans typically have three blades, while residential models have four or five;
  • blade irons:  connect the blades to the motor;
  • safety cable: on heavy fans, these are required to hold the fan in place in case the support housing fails;
  • flywheel:  connects the blade irons to the motor;
  • ceiling mount:  designs include ball-in-socket and J-hook;
  • downrod:  used where ceiling fans are suspended from high ceilings;
  • motor housing:  protects the fan motor from dust and its surroundings; may also be decorative; and
  • lamps: may be installed above, below or inside the motor housing.

Common Fan Defects

  • The fan falls. A ceiling fan that breaks free from its ceiling mount can be deadly. Fans must be supported by an electrical junction box listed for that use, according to the National Electric Code, and a fan brace box will need to be installed. While a particular junction box might support a fully assembled fan, during operation, it will exert additional forces (notably, torsion) that can cause the support to fail. Homeowners often overlook this distinction by carelessly replacing light fixtures with ceiling fans without upgrading the junction box, which should clearly state whether it’s rated to hold a ceiling fan.
  • The fan wobbles. This is a common and distracting defect that is usually caused when fan blades are misaligned from one another. Specific problems stem from minute differences in the size or weight of individual blades, warping, bent blade irons, or blades or blade irons that are not screwed in tightly enough. The ceiling mount may also be loose. Wobbling is not caused by the ceiling or the particular way that the fan was mounted. Wobbling will not cause the fan to fall, and there have been no such reports. Wobbling can, however, cause light fixture covers or shades to loosen and potentially fall. These items should be securely attached, with all screws tightly set in place. An easy way to tell if the blades are not on the same plane is to hold a yardstick or ruler against the ceiling and measure the distance that the tip of each blade is from the ceiling by manually pushing the blades. A homeowner can carefully bend the misaligned blade back into place. Blades can also be corrected in this way if measurement reveals that they are not equidistant from one another.
  • There is inadequate floor-to-ceiling blade clearance. No part of the fan blades of a residential ceiling fan (usually having four or more blades) should be closer than 7 feet from the floor in order to prevent inadvertent contact with the blades. Downward air movement is maximized when the fan blades are around 8 or 9 feet from the floor. For high ceilings, the fan may be hung to a desired height. Low-profile fan models are available for ceilings that are lower than 8 feet from the floor. Also, fan blades should be at least 18 inches from walls. For commercial ceiling fans (usually having three blades), no part of the fan blades should be closer than 10 feet from the floor in order to prevent inadvertent contact with the blades.  Underwriters Laboratories UL 507 Section 70.2.1 says:

    “The blades of a ceiling-suspended fan shall be located at least 3.05 m (10 feet) above the floor when the fan is installed as intended.”

Underwriters Laboratories makes exceptions if the fan blade edges are thick and the fan is turning slowly.
  • Blades are turning in the wrong direction. In the winter months, the leading edge of the fan’s blades should be lower than the trailing edge in order to produce a gentle updraft, which forces warm air near the ceiling down into the occupied space below. In the summer, the leading edge of the fan’s blades should be higher as the fan spins counter-clockwise to cool occupants with a wind-chill effect. On most models, the fan direction can be reversed with an electric switch located on the outside of the metal housing, but the same effect can be achieved on other models by unscrewing and remounting the fan blades.
  • An indoor fan is not designed for exterior use. Ordinary indoor ceiling fans are unsafe to use outdoors or in humid environments, such as bathrooms.  They will wear out quickly. Fans that are rated “damp” are safe for humid environments, but they, too, should never be used where they might come into contact with liquid water. Only fans that are rated “wet” are safe for such use, as they incorporate features such as all-weather, UV-resistant blades, sealed motors, rust-resistant housing, and stainless steel hardware.

Home Inspection – Windows

February 28, 2018 by spihomei

One part of any Phoenix or Prescott area home inspection we do is to look at, and operate, all of the accessible windows. This includes the inspector looking for signs of window seal failure. If multiple-pane windows appear misty or foggy, it means that the seal protecting the window assembly has failed. Let’s take a closer look at how window condensation happens, and what it may mean on a home inspection report.
First of all, Condensation is the accumulation of liquid water on relatively cold surfaces.  Almost all air contains water vapor, the gas phase of water composed of tiny water droplets. The molecules in warm air are far apart from one another and allow the containment of a relatively large quantity of water vapor. As air cools, its molecules get closer together and squeeze the tiny vapor droplets closer together, as well. A critical temperature, known as the dew point, exists where these water droplets will be forced so close together that they merge into visible liquid in a process called condensation.

Double-pane windows have a layer of gas (usually argon or air) trapped between two panes of glass that acts as insulation to reduce heat loss through the window. Other types of gas used in this space have various effects on heat gain or loss through the window. Some windows also have a thin film installed between panes that separates the space between the panes into two spaces, further reducing heat loss and heat gain through the window.

Silica Desiccant
A desiccant is an absorbent material designed to maintain dryness in the space it protects. In a double-paned window, silica pellets inside the aluminum perimeter strip absorb moisture from any incoming air that enters the space between the panes. If not for the silica desiccant, any moisture in the space between the panes would condense on the glass as the glass cools below the dew point temperature.

Silica gel has an immense surface area, approximately 7,200 square feet per gram, which allows it to absorb large amounts of water vapor. As the sealant protecting this space fails over time, increasing amounts of moisture-containing air will enter the space between the panes, and the silica pellets will eventually become saturated and will no longer be able to prevent condensation from forming.

Why Double-Paned Windows Fail:  Solar (Thermal) Pumping
Although double-paned windows appear to be stable, they actually experience a daily cycle of expansion and contraction caused by thermal pumping. Sunlight heats the airspace between the panes and causes the gas there to heat up and expand, pressurizing the space between the panes. At night, the window cools and the space between the panes contracts. This motion acts like the bellows of a forge and is called thermal pumping.
Over time, the constant pressure fluctuations caused by thermal pumping will stress the seal. Eventually, the seal will develop small fractures that will slowly grow in size, allowing increasing amounts of infiltration and exfiltration of air from the space between the panes.

Failure Factors

Windows on the sunny side of a home will experience larger temperature swings, resulting in greater amounts of thermal pumping, seal stress and failure rates.

Vinyl window frames have a higher coefficient of expansion resulting in greater long-term stress on the double-pane assembly, and a higher failure rate. Windows also experience batch failure, which describes production runs of windows, especially vinyl windows, that are defective, meaning that the pane assemblies have been manufactured with seals that have small defects that will cause the window to fail prematurely.

The Nature of Damage

If it’s allowed to continue, window condensation will inevitably lead to irreversible physical window damage. This damage can appear in the following two ways:

  • riverbedding.  Condensed vapor between the glass panes will form droplets that run down the length of the window. Water that descends in this fashion has the tendency to follow narrow paths and carve grooves into the glass surface. These grooves are formed in a process similar to canyon formation.
  • silica haze.  Once the silica gel has been saturated, it will be eroded by passing air currents and accumulate as white “snowflakes” on the window surface. It is believed that if this damage is present, the window must be replaced.

Detecting Failure

Condensation is not always visible. If the failure is recent, a failed window may not be obvious, since condensation doesn’t usually form until the window is heated by direct sunlight. Windows in the shade may show no evidence of failure, so your inspector will disclaim responsibility for discovering failed double-paned windows.

 

Recommendations for Failed Windows

According to industry experts, the glazing assembly can be replaced  approximately 75% of the time.  Occasionally, the sashes must be replaced, and only about 5% of those cases require that the entire window be replaced.

Be aware that there are companies that claim to be able to repair misty windows through a process known as “defogging.”

This repair method proceeds in the following order:

  1. A hole is drilled into the window, usually from the outside, and a cleaning solution is sprayed into the air chamber.
  2. The solution and any other moisture are sucked out through a vacuum.
  3. A defogger device is permanently inserted into the hole that will allow the release of moisture during thermal pumping.

There is currently a debate as to whether this process is a suitable repair for windows that have failed, or if it merely removes the symptom of this failure. Condensation appears between double-paned windows when the window is compromised, and removal of this water will not fix the seal itself. A window “repaired” in this manner, although absent of condensation, might not provide any additional insulation. This method is still fairly new and opinions about its effectiveness range widely. Regardless, “defogging” certainly allows for cosmetic improvement, which is of some value to homeowners. It may also reduce the potential for damage caused by condensation in the form of mold or rot.  Some skepticism exists about the effectiveness and cost effectiveness of this method of repair.

In summary, condensation in double-paned windows indicates that the glazing assembly has failed and needs repair or replacement. Visible condensation can damage glazing and is the main indication of sealant failure.

Windbreaks for your Home

February 19, 2018 by spihomei

It is a WINDY day here in Prescott Valley, Arizona!  So let’s talk a little about how you can use natural windbreaks to your advantage. Windbreaks are dense rows of trees and shrubs designed to reduce wind speed before it reaches a building.  During a home inspection I will pay attention to landscape items as it relates to the home, such as making sure trees and shrubs are not too close to the structure, but well placed trees and shrubs can do much to enhance not only the beauty of the home, but the also provide other perks for the homeowner.

Some of the advantages provided by windbreaks, beyond simple wind mitigation, include the following.Properly-designed windbreak protects a house
  • Many animals rely on windbreaks. Food, shelter from severe weather, nesting sites, and a means of escape cover are all provided by the vegetation that composes a windbreak. For example, the planting of windbreaks during the Dust Bowl of the 1930s is believed to have allowed the expansion of woodland birds and other creatures, such as Mississippi kites and fox squirrels. Birds, in particular, are known to rely on windbreaks for temporary cover during winter storms. Even large mammals, such as white-tailed deer, use windbreaks for cover, food and fawning. Employ a variety of trees and shrubs in your windbreak to create an abundance of different kinds of nuts, seeds and berries, which will, in turn, attract a diversity of wildlife.
  • While any vegetation will increase the appeal of an otherwise barren yard, a uniform, well-maintained windbreak can actually increase property values with their pleasing aesthetics. Also, they allow the homeowner to strategically screen out undesirable sights.
  • Windbreaks are effective for noise deflection. Windbreaks reduce the infiltration of traffic noise into a property by absorbing and deflecting it with leaves and large branches. In addition, traffic noises will be replaced with the sounds of rustling leaves or the singing of birds that are drawn to the vegetation.
  • Windbreaks provide snow control (okay, those of you in Phoenix can ignore this part!). A properly placed windbreak will prevent snow drifts in areas such as driveways and building entrances. Valuable time and effort can then be spent on activities other than snow removal.

Windbreaks work either by deflecting the wind up and over a building, thereby forming a protective wind shadow, or by catching it to reduce its speed. And as the windbreak captures the winter wind, so too does the wind chill diminish. For example, if the outside temperature is 12° F (-11° C), a windbreak can reduce a 20-mph wind to 5 mph, and the wind chill will be reduced from -22° F (-30° C) to a more bearable 8° F (-11° C).

The best windbreaks block wind close to the ground by using fast-growing trees and shrubs that have low crowns. Deciduous trees, while they are favored as shade trees during the summer, lose their leaves in cold weather, which makes them less effective than evergreens at stopping the frigid winter wind. The best choices are dense, fat, fast-growing conifers that will mature to a height higher than the roof. These qualities may be found with Norway, white and Colorado blue spruce. Again, those of you in Phoenix and Scottsdale will have to use something like fast growing oleanders or other dense shrubs to help.

Tips that you may find helpful:Windbreak

  • For maximum protection, plant your windbreak at a distance from your home of three to five times the height of the mature trees. Studies have shown, however, that the effective distance of wind reduction is sometimes as high as 30 times the height of the windbreak, depending on the tree species.
  • Do not plant trees too close to the home’s south side, as this will reduce the warmth supplied by the winter sun.
  • Arrange windbreaks in multiple rows to increase their effectiveness.
  • Do not prune the lower branches of the windbreak, as this will increase the wind speed near the ground.
  • Thin the trees and shrubs as they grow to ensure that competition does not jeopardize the health of the windbreak. For instance, you can plant trees 3 feet apart, but then you should remove every second tree when their crowns begin to intersect.
  • Incorporate numerous plant species in the windbreak to impede wind from ground level to the treetops. Even non-living yard features, such as walls, fences and raised soils, can be incorporated into a single windbreak.
  • Decide which direction the prevailing winds come from in your area so you know where the best places are to plant the windbreak.
  • Be careful to not plant large trees too close to the home, as they may fall during a storm, shed leaves or needles on your roof, allow pests to access your roof, or even penetrate your basement walls with their root structure. If you are experiencing any of these conditions, be sure to talk about it with your home inspector during your next scheduled inspection.
  • Arrange the windbreak in such a way that it will provide a conduit for breezes and desired winds.

Annual Home Inspections

February 5, 2018 by spihomei

The concept of an annual home inspection has been around for a long time, but it may just now be catching on that this is a good idea. Why wait until you plan to sell your home and then get overwhelmed with all the small items that you have not stayed on top of.  As a home inspector in the Prescott area, as well as the Phoenix metro area, we have seen houses that have so much going for them when they hit the market, but then once all the items from a home inspection come up the buyers get concerned with the potential added cost of fixing them, and it sometimes causes them to look elsewhere.

It is easy to stay on top of the maintenance items, and sometimes delay the more costly repairs that all homes need over time, by getting a “home health checkup” on a regular basis – just like going to the doctor for your wellness exams, or taking your car to the shop for routine maintenance. Your home is perhaps your largest asset, so maximize your investment and consider a regular home inspection to provide you with an easy to understand to-do list.

After the inspection you will have a clear idea of the items that need attention so that you may decide what you can do on your own, and what you may need a professional contractor to complete. Then you can enjoy your home more while you live there, and can have fewer surprises when you go to sell it.

Call us today to talk about what we can do for you when it comes to annual (or even semi-annual) “health” checkups for your home!

Relocating to Prescott? Tips to Make the Move More Eco-Friendly.

August 14, 2017 by spihomei

OLYMPUS DIGITAL CAMERA

As a Prescott area home inspector, I am here to help you prior to the big move into your new home, and having moved recently myself I know how stressfull and time-consuming a move can be! But rarely do we wonder about the impact the process has on the environment. This is amplified when moving to a smaller house or condominium, and additional decisions have to be made regarding items that must discarded in order to save space.  If we don’t make these decisions deliberately, our choices can generate a lot of trash, and waste energy and natural resources. Fortunately, we have other options so that, when the time comes, we can relocate — along with our stuff — responsibly.

Some measures to consider before moving day:

  • Buy less.  The less you accumulate, the less you will have to discard when it comes time to relocate. Also, fight the urge to be a pack rat by recycling and giving items away as they become obsolete to you. If you put off these decisions until the day you have to relocate, many of the things that you’re on the fence about keeping will likely end up in the trash because you’ll be too preoccupied by the move to put the effort into thoughtful and responsible disposal.
  • Discard items in a responsible manner, rather than merely throwing them away. Non-biodegradable trash doesn’t disappear; it just accumulates in new locations where it contaminates groundwater and soil, off-gasses methane and other greenhouse gases, and overwhelms otherwise useful land. By taking a few extra steps, you can save money, help others, and minimize your impact on the environment.
    • Recycle. With a minimum of effort, you can recycle old magazines and newspapers that you do not want to take with you to your new home. Glass, metal and plastics are also easily recyclable, and you will conserve some of the raw materials and energy required to produce these items by re-offering them. Many of the items you clean out from your home might be recyclable in your community curbside or drop-off recycling program. To determine what items you can recycle, contact your local environmental agency or waste-pickup service.
  • Sort through your belongings and decide what you don’t want to take with you, separating them into defined groups based on how best to dispose of them. For instance, separate your unwanted items that are in good working order, and can be reused by a friend or neighbor, from other items that require special disposal, such as hazardous chemicals or large, bulky items. See the following sections on how to identify items for reuse, recycling and special disposal.

Common recyclables include:

      • cardboard;
      • mixed paper;
      • newspapers;
      • glass bottles and jars;
      • plastic bottles and jugs; and
      • scrap aluminum and cans.

Many items can be dropped off for recycling at nearby locations, such as:

  • plastic grocery bags that are often accepted for recycling at grocery stores;
  • used electronics, such as cell phones and computers, which are collected for recycling at electronics stores, school vocational programs, and by municipal governments;
  • bulky consumer goods.  Your municipality, by special request or at designated times of the year, may collect appliances and other large discards, such as non-working refrigerators and broken furniture.
  • Sell.
    • Neighborhood yard sales are a fun way to get rid of items and make a little extra money.
    • Websites such as eBay, Craigslist and Freecycle provide ways to advertise online, often for free, in order to unload unwanted items.
    • Antiques can be cleaned and sold to antique and consignment shops.
  • Donate.  Try putting items on your curb with a “free” sign.  Or, take them to your local Salvation Army Store, ARC Store, DAV Store, Goodwill, women’s shelter and homeless shelter as the items lose their usefulness to you.  Keep a spare bag in the trunk of your vehicle, and take the reusable items that you run across out to your car.  Before you know it, you will have a full bag to drop off at a thrift store or a collection drive.  Charitable donations to many non-profit organizations are often tax-deductible. Popular donated items include:
    • clothing and footwear;
    •  bedding, curtains and towels;
    • some toiletries;
    • books and magazines, which can be donated to your local school, library, or community or senior center;
    • furniture;
    • kitchenware and small, working appliances;
    • consumer electronics;
    • unwanted entertainment items, such as CDs, DVDs and video games;
    • larger items, such as computers, and stoves and refrigerators;
    • vehicles; and
    • unopened food items, which will be accepted at food banks and shelters.
  • Hire an environmentally conscious moving company. When searching for a professional service, select a competent expert who is concerned about nature and takes active steps in employing environmentally sound practices. Ask the company:
    • Do they encourage the use of used boxes rather than insisting that each customer pay for new
      boxes? An environmentally conscious transporter should be happy to take the materials
      from you after your move to pass on to his or her next customer.
    • Are their vehicles fuel-efficient?  Ethanol-powered trucks are a bonus, although high mile-per- gallon diesel and gasoline trucks are positive choices, too.
    • Moving vehicles may also be fitted with devices that emit a sound to prevent animals from
      wandering into the road. It may seem trivial, but moving vehicles spend a long time on the
      road, and these devices can and do save the lives of many animals. In Australia, they use
      “hopper stoppers” to protect kangaroos.  In much of the rest of the world, deer are a bigger
      problem.
  • If you don’t use a professional moving company, be smart about boxes and packing materials. Rather than buying these items new, which unnecessarily adds to the expense of moving, find them used. In most cases, old boxes work just as well as new boxes. Liquor stores, grocery stores, hardware and other retail stores are usually happy to give away large cardboard boxes they no longer need and would have to otherwise discard or recycle. Calling around first will save you frustration and the emissions of driving around town to individual stores. You can also ask friends and neighbors if they have materials you can have or borrow. Moving boxes are also popular “freebies” on Craigslist. By following this tip, you will have reduced the number of trees that must be chopped down and boxes that must be manufactured. Also, by reusing boxes and packing material, you keep them out of landfills. When you are finished moving, keep the packing materials for future use, or pass them on.
  • Properly dispose of hazardous household items. While cleaning out and packing up the basement, garage or shed, you might run across some products such as cleaners, pesticides and paints, which are corrosive, flammable or otherwise dangerous to the environment and human health, if not disposed of properly. See if your community has special drop-off sites or holds periodic collection days for safe recycling and disposal of these products. Some stores offer free recycling for returned used goods at the point-of-purchase.

Common hazardous substances include:

    • cleaning supplies;
    • art and photographic supplies;
    • spent printer cartridges;
    • leftover paints, stains and varnishes;
    • light bulbs and fluorescent tubes;
    • spent batteries for laptops, digital cameras and other personal electronics;
    • old car batteries;
    • antifreeze;
    • used motor oil; and
    • pesticides and weed killer.

Also, beware of hazardous chemicals that may contain gasoline, oil or other toxins. Local environmental agencies across the country have set up programs for homeowners to trade in their old gasoline-powered lawnmowers and electric gardening equipment. Contact your local solid waste collection outfit or environmental agency to inquire about these programs.

In summary, relocation is often hectic and expensive, but it doesn’t have to damage the environment.  You can also take easy steps to pare down your material belongings and keep them out of the landfill by reducing, reusing and recycling.

 

Home Inspection of Windows

August 2, 2017 by spihomei

Windows are one of the things that get looked at when we do a Scottsdale or Prescott home inspection for a buyer or seller. This evaluation of windows determines not only if they open and close properly, but also looks for issues like broken seals or other defects that may need to be addressed or looked at more closely. If you decide to replace defective windows either before or after the sale of the home, here are a few items that may help you understand what is best for you.

First of all, if you are the seller or the buyer and a home inspection reveals defective windows, don’t panic! The cost to repair or replace the window may not be all that bad, and the potential savings in energy even better.

The Potential Energy Payback

The U.S. Department of Energy estimates that the average household spends between $1,500 and $2,500 annually on energy bills, and attributes about 45% of the expense to heating and cooling. With a window replacement project, selecting the right windows can have significant impact not only on the price of the project, but also on the potential for cutting energy expenses, which is especially important for those who intend to remain in their homes for years after the project is completed.

But when it comes to replacement windows, one size does not fit all. Homeowners need expert guidance to select products that offer the best value for their budget, climate, and the orientation of their home with respect to sun and shade. They should also be careful to contract only with installers who are well trained, efficient, and guarantee their work.

Are Replacement Windows the Right Choice?

It’s important to first determine what type of window project is best for your home. Technically speaking, replacement windows are designed to fit inside an existing window frame so that the siding and trim needn’t be disturbed or replaced.

New-construction units have nailing fins and are designed for installation in a rough opening.

Installation of prime windows requires removal of siding and trim around the window, then restoration of the finishes once the window is in place.

If an existing window frame is relatively square and free of rot and other defects, replacement windows can work well and save lots of time and money. But if an existing window has shifted out of square or there are signs of moisture infiltration in the surrounding wall, the old window and surrounding finishes should be removed. This gives the installer a chance to inspect the framing, find and flash the infiltration source, add insulation where necessary, and seal the opening against water and air leakage.

Replacement Window Material Choices

Vinyl
Vinyl replacement windows are a popular choice due to their affordable cost and low transmission of heat and cold air through the frames. They require little or no maintenance, which should always be factored into the value proposition.

There’s wide variation in the quality of vinyl frames and sashes in the market. More dimensionally stable vinyl frames are extruded with matrices of reinforcing cells for greater strength, and have joints that are welded. These features improve the potential for weather-tightness, energy performance, and lasting attractiveness.

One note: Residents of historic districts and certain homeowners’ associations should be advised that vinyl replacement windows may be prohibited and should check with authorities before installing them.

Wood
Wood replacement windows are more expensive than vinyl but offer comparable heat/cold transmission ratings. Wood is a good choice for older, traditional homes and in districts where vinyl and metal are prohibited by code. Though wood frames require routine maintenance, the extra expense can usually be avoided with approved metal or vinyl cladding applied at the time of installation.

Composition or Fiberglass
Fiberglass replacement windows are comparable in price to wood windows, and they boast better dimensional stability than vinyl. They have inherently good heat/cold transmission resistance that can be augmented with foam insulation applied within voids in the extrusions. Fiberglass windows are available in an array of factory-applied colors that require no maintenance.

Aluminum
Aluminum replacement windows are relatively inexpensive but have poor thermal transmission characteristics, especially when frames are constructed without a thermal break. However, they may offer decent value with the right glazing in warm climates. Factory-applied finishes need no maintenance.

Glazing Choices

Along with selecting a frame and sash with high resistance to thermal transfer, the right glazing can have an enormous impact on a replacement window’s energy-saving performance and, therefore, its long-term value. Glass by itself is not a particularly good insulator, but most replacement window suppliers offer a number of glazing options that can double or triple energy performance, in comparison to single glazing.

Selecting Replacement Windows Based on Orientation

ENERGY STAR, the U.S. Environmental Protection Agency’s program to help consumers and businesses conserve energy, makes some very specific recommendations for window U-value and SHGC ratings with respect to their orientation toward the sun:

In cold climates:

  • South-facing walls: Shaded windows should have a higher SHCG for more passive heat gain in winter and lower U-values to reduce heat loss. Unshaded south-facing windows should have lower SHGC to prevent excessive heat gain in summer.
  • East- and west-facing windows should have lower SHGC ratings.
  • North-facing windows should have the lowest U-value possible; SHGC ratings are unimportant.

In warm climates:

  • East-, west- and south-facing windows should have low SHGC and should be shaded to prevent excessive heat gain.
  • All windows should have low U-values to minimize heat loss and reduce air-conditioning loads.

Go by the Numbers

For guidance in selecting the best values in replacement windows, analyze and compare the ratings found on the NFRC/ENERGY STAR labels on the products offered within your budget range.

Lots of info here, sorry if it is overwhelming, but all windows are clearly not the same, so ask your local expert to help you, and then enjoy those new windows and hopefully the energy you will save in the long run.

Conserve Energy and Save Money

July 14, 2017 by spihomei

In addition to doing home inspections in Prescott and Prescott Valley and parts of the Phoenix area, we also do home checks on vacation homes. I recently advised one of my clients that it was time to update the HVAC unit on their vacation home that I manage for them in Scottsdale. They noticed higher than normal bills recently, and while there HAS been a record breaking heat in the valley this summer, part of the problem for them is outdated equipment. This guide is primarily aimed at homeowners who are thinking of upgrading or replacing their home’s existing heating or cooling systems. It also contains useful information for people who are having a home built for them, and for those who want to reduce their energy consumption in general.

A Wise Choice
 
The options presented will help you to select heating and cooling systems that meet the needs of both your lifestyle and your checkbook. Besides the obvious savings for you that occur by lowering your consumption, by reducing demand for energy through conservation, or, in the case of electricity, from shifting consumption to times of lower demand, together we can lower the market price for the energy that is consumed. The advantages of investing in energy efficiency aren’t only felt within your family budget – they are realized in the cleaner environment that goes hand in hand with more efficient systems and the wise use of energy.


Before You Start
Putting an energy-efficient heating system into a drafty, poorly insulated house will reduce your energy bills. But you’ll notice a more dramatic savings and even make yourself more comfortable if you also make your entire house more energy-efficient. How? Here are some ideas:
  • Weatherstrip and caulk to seal air leaks. You may have to replace uncontrolled sources of air with designed sources to ensure proper ventilation.
  • Increase insulation levels where appropriate (such as in the attic and walls) to reduce heat loss in winter and heat gain in summer.
  • Open drapes on south-facing windows on sunny winter days so that the sun’s energy can help heat your home, and close them in summer to help keep your home cool.
  • Choose energy-efficient products when replacing windows and doors.
By making your house more energy-efficient, your heating and cooling systems will work less, and you may reduce the capacity needed when you replace your systems, which means more savings for you.
Choose the Right Equipment
In order to correctly size new heating and cooling equipment, your contractor must analyze how much heat is lost from your home in winter and gained in summer. Ask for this heat loss/gain analysis in writing, including the method used to perform the calculation. This calculation should take into consideration such factors as the size of the house, its level of insulation, and the condition of windows and doors. If the heat loss and gain is significant, and you haven’t already taken steps to increase the energy efficiency of the house, now is the time to do it.
Avoid the temptation to simply choose the same size equipment that already exists in your house without doing a heat loss/gain analysis. Your home has likely been altered over the years, and the system might even have been the wrong size at the start. An oversized unit will usually operate below peak efficiency, and both oversized and undersized units can adversely affect the comfort of your home. Any installation involving combustion equipment should include steps to ensure that there will be an adequate supply of air for combustion and venting, and that other air-exhausting equipment will not cause problems.
I am not going to go into detail about all the different types of units out there, or the SEER ratings… but I am more than happy to talk to you about these things if you care to give me a call.  In summary, homeowners can reduce their energy consumption by adopting the strategies offered in this guide and contacting an inspector who may be able to guide you in ways to conserve energy and save money.
