Summer Insulation Best Practices

Summer Insulation Best PracticesWe all know insulation is important in the winter It keeps warm air from rising into the attic, allowing it to stay in your home longer, keep your house more comfortable, and save you energy. But did you know that insulation is just is important in the summer?

Here’s how insulation can help you in warmer weather, as well as a few tips on making sure your home is properly insulated.

Summer Insulation Benefits

Insulation does two things in warm weather. First, it keeps warm air in the attic. As you cool your home, a lot of that cold air flows outside, only to be replaced by hot air from your attic, flowing in. Attic insulation helps keep that hot air out, allowing your home to stay cool longer. Wall insulation can help too, keeping the warm, humid, outdoor air from getting in, so your A/C can work more efficiently.

The other thing insulation does is protect your roof. The top of your roof is hot in the summer, as the sun beats down on it. When cold air leaks into the attic from your home, it makes the underside of the roof cooler. That temperature disparity can damage your roof, causing leaks, as well as leading to mold and mildew. Insulation keeps the heat in your attic, so your roof temperature remains even.

Summer Insulation Tips

The most important place to insulate is your attic. Before you do, though, be sure to find and seal any air leaks that would allow hot air to flow into your home. Loose-fill is inexpensive, effective, and provides good coverage, making it an ideal choice. Make sure there’s between 10 and 14 inches of insulation in the room, and seal and insulate the attic door as well.

You might also consider insulating your ducts. This helps keep cold air cooler as it flows through them, allowing it to cool your home more efficiently. Talk to your HVAC contractor about how to insulate ductwork.

How Furniture Can Affect Your HVAC

How Furniture Can Affect Your HVACTechnology has advanced to the point where energy efficient furniture does exist. It can store and release energy to charge batteries, run lights, or provide the same HVAC effects your furnace or A/C does. While it’s not ready for the market yet, it shows that furniture is, and will continue to be, a part of the home that can contribute to your comfort.

Comfort and Heat

Some products used in homes offer more comfort than others, especially with regard to thermal management. Upholstered (with padding) furniture is far more comfortable year-round than hard plastic chairs. The fabrics and internal padding absorb heat and moisture, keeping you warmer in the winter and cooler in the summer. A hard plastic chair, for example, does not absorb moisture. It feels cold in the winter and hot in the summer.

Insulating Value of Furniture

Even the wood that furniture is made from has some insulating value, which is a property that contributes indirectly to comfort, especially when it’s cold. Wood products that are less dense and lighter in weight. They can hold more air than dense wood. The ability to retain air in small pockets is a basic characteristic of most insulation products.

Color and Temperature

Not only do the materials from which the furniture is made have HVAC effects, so does its color. Dark colors absorb heat while light colors reflect it. Anything that reflects heat will be cooler, even on a hot, sunny day. Flat roofs on homes are often painted with bright white reflective paint, while pitched roofs in the mountains use dark metal roofing for easier snow removal.

The same holds true with your home. Light-colored furniture on the patio makes sense since you will use it more in warm weather versus cold. Porous textiles that are UV-resistant will hold up better to the solar exposure and dry faster in the outdoor environment.

Furniture does have HVAC effects that you can use to your advantage. You can also get more efficiency from your system by having it serviced by Powers Heating & Air, providing HVAC services for Peachtree City homeowners.

How Does Color Affect Temperature?

How Does Color Affect Temperature?For centuries, people have equated colors with temperature effects. Darker colors represent the cooler months when we need to supplement home heat. Light colors reflect heat and are the colors of spring and summer when heat reflection and dissipation is desirable.

Colors and Degree Days

Over the last five years, the Peachtree City area has needed more home heating than cooling by about one-third. The Weather Service collects temperature highs and lows, along with degree days. They use equipment to measure the temperatures 24/7 and apply a formula that tells them how many total degrees your house needs heating or cooling based on temperature fluctuations during that 24-hour period. The base temperature is 65 degrees F. If the air stayed at 65 degrees for a 24-hour period, it would be a 0 heating or cooling degree day.

Since the heating degree days outnumber the cooling degree days, the colors for your home should lean more toward the dark versus light. Instead of a light exterior, you might save more energy by using a medium-brown hue. Light homes are far more common in Florida where cooling degree days dominate the weather and the temperature effects of dark colors raise cooling costs.

Roofing Colors

Even though darker colors absorb heat, they don’t necessarily make a good roof. The heat from the shingles can infiltrate into the attic. The U.S. Department of Energy (DOE) has found that cold attics with enough insulation prevent ice dams, which are dangerous and harmful. In fact, the DOE has a designation for Energy Star light-colored roofing materials that reflect heat versus absorb it.

Interior Design Colors

Since Peachtree City has its share of hot weather, mixing the light and dark colors indoors gives you a chance to surround yourself with colors that work well year-round.

It does help to think about the temperature effects of the colors you use. The pros at Powers Heating & Air want to help you make your home as energy efficient and comfortable as possible. We provide HVAC services for Peachtree City homeowner.

Know These HVAC Airflow Problems

Know These HVAC Airflow ProblemsAirflow problems with your HVAC system can leave you dealing with discomforting issues like hot or cold spots, uneven temperatures in different rooms, and/or a drop in conditioned air output from the registers. What starts out as a gradual loss of comfort can escalate into a costly equipment breakdown or failure, so it’s vital to have the problem addressed. Here’s a look at some of the most common causes or airflow issues and what to do about them:

Obstructed Registers and Duct Openings

If you’ve closed some registers, or your return ducts are covered by furniture, drapes, throw rugs, toys or other items, it can cause temperature inconsistencies in different areas of your home and a damaging imbalance in system airflow. You can fix this by wiping down each vent cover and vacuuming out the duct openings, and then checking that your louvered registers are completely open and all supply and return vents are free from obstructions.

Clogged Air Filter

If you’ve neglected to change your system’s air filter and it’s become clogged by dust and debris, you’ll notice a drop in airflow at the registers. Restricted airflow can also increase your HVAC equipment’s workload and energy consumption, or even ruin a component. Checking the filter monthly and replacing it whenever it looks dirty is the best way to prevent such problems.

Ductwork Flaws

A ductwork system that’s poorly designed, damaged, or leaking can hinder proper airflow through your HVAC system. A trained HVAC technician should inspect your ductwork to determine the cause and the right remedy, which may involve repairing, sealing and insulating or replacing the ductwork.

Oversized Equipment

If your existing HVAC system wasn’t sized properly, it may be too large to effectively heat or cool your home. HVAC components with too much capacity will short cycle, resulting in a decline in airflow from the registers every time they cycle off. To solve this, a knowledgeable HVAC professional will need to complete a detailed load calculation and install correctly-sized new equipment.

How Insulation Affects HVAC Efficiency

How Insulation Affects HVAC EfficiencyHVAC efficiency depends upon more than just the make and model of your air conditioner or furnace. Insulation is one of the factors that can make or break both optimum energy efficiency and consistent comfort in your house.

 

Insulation For All Seasons

 

Heat energy is always in motion from a warmer zone into a cooler zone. Proper insulation effectively inhibits both heat gain in summer and heat loss in winter and supports maximum HVAC efficiency. The most cost-effective location for household insulation is usually the attic. Here’s why:

  • Solar heat radiating through the roof overheats the attic in summer, causing rooms below to become hotter, too. A bed of fiberglass or cellulose insulation in the attic floor effectively inhibits heat radiation through the ceiling and reduces the cooling load on your air conditioner.
  • In winter, heat from the furnace naturally rises in living spaces, radiating up through the ceiling into the colder attic. Proper insulation in the attic floor resists heat transfer through the ceiling and keeps heating costs lower.

How Insulation Pays Off

By reducing the effect of heat gain and heat loss, insulation boosts HVAC efficiency, maximizes performance of your air conditioner or furnace and helps control cooling/heating costs.

  • Shorter cooling cycles means the A/C compressor—often the largest single electricity consumer in a typical house—runs less and monthly electricity costs are reduced.
  • Gas-fired furnaces also use less fuel to keep the house warm as insulation reduces heat loss into the attic.
  • Manufacturer’s efficiency ratings are more accurate. Both the SEER efficiency rating for air conditioners and the AFUE rating for gas-fired furnaces are helpful factors in predicting the operating costs of a particular unit. The reliability of these efficiency calculations assumes that proper insulation is installed in the house.
  • Components of efficient HVAC units receive less wear and tear. System service life is extended due to shorter cycles and repairs are less frequent.
