Should Windows be Open While my AC is On?

Opening your windows can help vent your home in the summer. During the evening it also allows warm air to escape provided the indoor temps are higher than the outdoor temps. However, should you open you windows on a hot day while your AC runs?

Your AC is responsible for delivering cool air throughout your home. On hot days it is important to keep that air inside your home for as long as possible. The more that cool air escapes, the harder your HVAC system has to work to replenish those cool temps. If your windows are open, you are literally sending that cool air out the door!

Drafty windows, leaky doors and other energy inefficiencies are main culprits for cool air loss, higher energy costs and things that make your HVAC system work way harder than it has to to keep you comfortable. An overworked HVAC system eats into the lifespan of your unit, resulting in more breakdowns and ultimately, expense.

Open windows not only let warm air in, but can also let in dirty air if the outdoor air quality is bad. Once dirty air is inside your home, it will get circulated and cause extra work for your furnace filter to try and trap. Dirty air not only comes into contact with your filter, but other HVAC parts and equipment.

Don't get me wrong, sometimes during a rain, or a nice crisp night it is great to open your windows and let some fresh air in. But on hot days when the outdoor temps are higher than inside, or when the air quality is subpar, keep your home sealed as tight as possible and let your HVAC cooling system do its job the most efficient way it can.
