Is It Bad To Have Your Windows Open AND Run Your AC?

March 30, 2023 | Blog

It’s hot outside. Your house is stuffy and you want to cool it down as fast as you can. You may be tempted to open your window while your AC is running. After all, some fresh air could help your air conditioner out so it doesn’t have to work as hard, right?

Wrong. Although it sometimes seems harmless to run your AC while your windows or screen doors are open, it can actually damage your AC and increase your electricity bills. At Baldwin Heating & Cooling, we recommend you save your AC this summer and choose to get fresh air outside instead of bringing it in.

What’s Wrong With Opening The Windows?

Although there’s nothing inherently wrong with cracking open a few windows from time to time, we don’t advise leaving your AC on while a window is open. We have your back at Baldwin Heating & Cooling and we want to make sure your AC lasts as long as possible. The following negative consequences are likely to happen by running your AC while a window is open:

Increased Need For AC Maintenance

An air conditioner works by blowing cool air into a room or house. Once the space reaches the desired temperature (determined by the thermostat), the AC will shut off, turning on again once the temperature has risen.

When you leave a window open, some of the cool air dispersed by the system is lost to the outdoors, and the air conditioner has to work harder to regulate the temperature of the space. Constant use of the machine wears down the various internal components, which increases the need for AC maintenance.

Decreased Energy Efficiency

It’s only natural that along with AC overuse comes higher electricity bills. We’ve already established that when your windows are open while your AC is on, your AC has to work much harder to cool down a space, which means it uses more electricity. If you want to save money this summer, it’s best to keep your windows shut.

Damage From The Outdoors

When your windows are open, particles like pollen, dust and pollution enter your home and make their way to your AC unit. These particles coat the internal components of the machine, clogging it and making it harder for it to run efficiently.

Open windows also let in humidity. When humidity levels rise, the AC has to work overtime to cool down the room, decreasing the machine’s efficiency and wearing out the various components. Humidity can also lead to the growth of mold in your air ducts, which contaminates your home’s air.

Excellent install of a generator by Jake & Ryan. They went over and above, working late waiting for the utility inspector to come out for final inspection. Couldn’t be happier…these guys are the best.
