How does an air conditioner work?

Lots of homeowners believe that air conditioners make the air in your home cooler, but it actually removes the heat from your home, directing the hot air outside. That hot air goes across a cold indoor coil where refrigerant in the lines sends the heat to the coil in your outdoor unit, releasing the hot air outside. This cycle continues until the indoor temperature reaches the desired level that you set on your thermostat.
