How Windows Affect Your AC Performance

While your AC hums along this summer, it’s time to talk about windows.

Sometimes “air conditioning maintenance” means maintaining things that aren’t technically part of your HVAC system. The best, most energy-efficient and state-of-the-art air conditioning technology can’t always overcome poorly maintained, poorly insulated spaces.

And now it’s Florida summertime. And the harder your AC has to work, the shorter its lifespan—and the higher your energy bill will be.

Windows can be a major key to AC performance, especially here in Sarasota-Manatee. Here’s how.

Windows Are a Blessing and a Curse

Windows can be an architectural conundrum. As part of our home or office environment, we want natural light and views of world just outside. We also want to be able to open them for fresh air and even a breeze (when the weather allows).

But windows also represent weak points in a building’s barriers against water, humidity, heat, dust, airborne contaminants and even insects. They let light and beauty inside, but they let a lot of other things inside, too.

Windows Affect Your AC Performance

By allowing heat inside, and sometimes by letting cool air out, windows can make your AC work harder than it has to.

Of course, your air conditioning doesn’t just cool your air; it conditions it. That means reducing humidity and filtering out dust and other airborne detritus.

  • Old windows, thin windows, and windows that face sunlight for much of the day will heat the air inside your house like an oven.
  • Poorly sealed windows, and ones that are left open while the AC is on, let cool air out and warm, wet air inside—plus bugs, salt, dust and who knows what else.


Any of these window issues exponentially increases your AC’s workload.

Now take into account our environment here in Sarasota and Bradenton. Not only is it very hot and very humid, but we’re dealing with salty air and a lot of bugs. If your windows aren’t doing their job, your AC is having to contend with all of these things.

You may have the best HVAC system on the market, but it can’t dehumidify all of Florida in the summertime. Your windows need to help out.

How to Improve AC Efficiency Through Your Windows

 Fortunately, you have options. You can improve your windows—and thus improve your AC performance—no matter your budget.

 Seal your windows using caulk, special sealant and/or weather-stripping.

  • Add adjustable curtains or blinds, especially to windows that get a lot of sun.
  • Keep blinds closed during the sunniest hours of the day.
  • Consider outdoor landscaping that shades windows (without touching the house, as this can bring bugs).
  • Add window tinting or thermal-blocking inserts.
  • Replace old windows with double-pane or triple-pane windows, or vinyl-insulated impact windows. (Today’s storm windows are often great for energy efficiency, too.)
