How Do Air Conditioners Actually Work? – Fresh Air Cooling and Heating

With cooling seasons that stretch well into fall, our AC systems work hard for a long time. Understanding the basics of how your system works can help you recognize problems early.

Air Conditioners Don’t Generate Cool Air

This is a common misconception. Your AC doesn’t create cool air; it removes heat from the air already inside your home. Here’s how:

Refrigerant is the heat transfer fluid that makes this possible. It travels to the indoor evaporator coil, where it evaporates and absorbs heat from the surrounding air. That cooled air is then distributed throughout your home via ductwork or, in a ductless system, through refrigerant lines.

The absorbed heat has to go somewhere. The refrigerant carries it to the outdoor condenser coil, where it condenses and releases that heat outside. The compressor drives this cycle continuously until your home reaches the desired temperature.
