Heat Gain Promotes Loss of Efficiency During the Cooling Season

It’s inevitable during the summer that some heat will enter your home, which will then require you to run your A/C more often. However, there are many simple methods to minimize heat gain that will make a significant impact on your energy bills.

Evaluate the Windows

Windows account for almost half of the heat gain in an average home. To reduce heat gain through windows, start by keeping blinds or draperies closed during the day. Most of the heat comes from direct sunlight, so if you have no blinds, do your best to cover up the windows that get direct sunlight on the outside with plants, awnings or shade screens. Finally, the next time you put in new windows, pay careful attention to their shading coefficients; aim for windows with as low a coefficient as possible.

Insulate

While you may think that insulation is intended to keep warm air in during the winter, it does so by impeding heat transfer, which is handy in the summer as well. Your exterior wall insulation should have a minimum R-value of 19, while ceilings should have at least an R-30 rating.

You should check for air leaks around windows and doors at least once a year to see if leaks are allowing warm air to enter. You can seal these on your own with caulking and weatherstripping. The alternative is to call in a professional to perform a blower door test, which will pinpoint all the leaks if you are having trouble finding them.

Ventilation

While you want to keep cold air in your home, it’s also important to let hot air out. In a typical attic, the air can easily reach well over 100 degrees, which can damage your roof and will also lead to some heat gain to the rest of the home. It’s important that you have sufficient attic ventilation, and that if you do, it works as intended.
