How It Works

Window air conditioners can be installed permanently or seasonally. They use an indoor and outdoor coil - along with a set of fans - to cool your room and remove heat. It generally takes more time and energy to cool humid air than it does to cool dry air. For efficient mobile cooling around your home, consider a portable air conditioner.

What Can Go Wrong?

If there’s a problem with your air conditioning unit, you’ll be the first to know. When the heat sets in, it’s important to remember that a dusty filter is the most common and easily solved problem you’ll run into. In rarer cases, the interior and exterior coils may need cleaning.  

If your room isn't cooling within five minutes - and the air filters are clean - get a professional diagnosis. There may be a problem with the refrigerant charge, compressor, condenser or fan. 

Environmental Impact

Window air conditioners typically use between 5,000 and 8,000 British Thermal Units per hour (BTUh). Even a 5000 BTU air conditioner can emit large amounts of carbon dioxide (CO₂) over the cooling season, so it's important to maximize efficiency when you can.
