Is It Bad To Leave My Windows Open When I Have My AC On?Leaving your windows open while running your air conditioner can lead to several undesirable consequences. You run the risk of reducing the efficiency of your air conditioning system because warn air from the outside can enter your home. Additionally, dust and other pollutants may also enter your home and negatively impact your home’s indoor air quality. In order to maximize the efficiency and effectiveness of your air conditioner, Peters Associates recommends that you keep windows and doors closed while your AC system is running. This helps to maintain a controlled indoor environment and ensures that the cooling system operates efficiently.

You may think that leaving the window open with the air conditioning on is a harmless practice that will allow you to get some fresh air during the summer. However, it is not a very good idea and can counteract all of the hard work that your HVAC system is doing. Here is why you should keep your windows closed while the air conditioner in running.

Keep the Cool Air in

Air Conditioners produce that vital cool air that keeps you comfortable when it’s hot out. However, that air needs to remain inside the home in order for your HVAC system to do its job. This can only occur when the windows are kept tightly closed. An open window, or even a crack in one, is enough to let out the cool air.

Don’t Make Your Air Conditioner Work Harder

When you have cool air escaping the home, you will need to leave your air conditioner on a higher setting to get the job done. As a result, your HVAC system will likely need to be kept on longer, therefore getting little rest. This will place a higher strain on your HVAC system and can lead to it breaking down prematurely. Going easy on your air conditioner can lead to a longer life and lower electricity bills.

Maintain Good Air Quality

Maintain Good Air QualityWhen you leave the window open, not only does air escape from your home, but dirty air also comes in. This will mean that you and your family are breathing in dirty air that is largely being recirculated in your home by the air conditioner. The resulting dust can also harm your HVAC system by coating its parts and coils and inhibiting the system from fully doing its job.
