How to Keep Your Garage Cool This Summer

Salt Lake county residents are no strangers to hot, dry summers. In June, July, and August, temperatures average above 80 and 90 degrees, with some days reaching a whopping 100 degrees.

Although you may be able to tolerate the weather from the air-conditioned comfort of your living room, you might not have a safe or easy summer if you work regularly in your garage. Since many garages don’t connect to the central heating and cooling systems, your garage may likely reach stifling temperatures this season, increasing your risk of heat stroke and heat stress.

If you plan to spend extra time in your garage, or if you must store items that don’t tolerate heat well in your garage, try the following tips to keep the area cooler and more comfortable.

Replace Your Aging Door

Assuming you regularly repair and maintain your garage door, it should last around 30 years or more before it needs replacement. However, individual door parts have a much shorter lifespan, and most experts recommend replacing doors installed before 1992, as these older doors lack the latest safety features that protect your family.

If your door needs replacement, opt for one that features insulation. Insulated doors minimize heat transfer from the outside, allowing your garage to maintain a more comfortable internal temperature. As you search for doors, double-check the R-value. A higher R-value offers greater insulating power, so the door with the highest R-value will resist heat more effectively.

Install Additional Weather Stripping

Proper insulation does an excellent job keeping hot air out and cold air in during the summer. However, if your doors or windows have any cracks or gaps in their frames, your garage will still heat quickly during the summer, despite the insulation. Only a tightly sealed garage will maintain a steady temperature.

Weather stripping seals the gaps under and around your garage door and around your window frames, preventing warm drafts from seeping inside. Additionally, weather stripping keeps dirt, dust, and debris out of your garage, so you don’t have to continually sweep your garage during the summer.

If you still have gaps in your walls and frames, you may need caulk the seams and joints in your garage. However, be careful not to caulk any seams that allow your garage door to open and close.

Choose a Lighter Paint Color

Your home’s exterior color palette can make or break your property’s resale value. The right shades of cool blues, stone grays, and olive greens can give your home a classy, uniform, and earthy appearance. But when you choose dark colors for your exterior paints, you can expect higher temperatures during the summer.

Dark colors absorb the sun’s rays more effectively than light colors, and as a result, darker colors contribute to the rising heat in your garage. Furthermore, the more heat your garage door absorbs, the more it expands (and contracts) with shifting temperatures. Over time, dark-colored garage doors will wear away more quickly than their light-colored counterparts.

Although white is your safest bet when you want to minimize heat absorption, you don’t have to stick to the traditional eggshell and white dove hues if they clash with your current trim and siding.

Light shades of gray or brown can match your overall color scheme while hiding dirt. If you prefer a more adventurous color scheme, paler shades of Neptune green or Palladian blue can keep your garage door cooler and more suited to your tastes.

Talk to a Technician About Cooling Your Garage

These techniques should lower your garage temperature by a few degrees, but they might not solve your cooling problems completely. For more ways to cool your garage, talk to a professional technician. He or she can assess your current layout and design and recommend solutions for improving air flow while minimizing heat transfer.
