How Your Air Conditioner Works

You know your AC keeps your home cool and comfortable. Find out what happens behind the scenes as your split-system AC battles the heat.

The Cooling Process: 1. Compressor squeezes refrigerant to raise its temperature. 2. Refrigerant leaves the compressor as a hot high-pressure gas

1. Gas flows into the condenser, which dissipates heat.
2. Refrigerant leaves condenser as a cool high-pressure liquid.
3. Line set connects condensing unit to evaporator on top of the furnace.
4. Liquid enters evaporator, which drops the pressure.
5. It’s now a cool low-pressure gas.
6. Blower fan distributes cooled air throughout ductwork.
7. Hot air in room rises and is sucked into return vents.
8. Vents circulate it back over the evaporator coil.
9. Gas is sent outside to compressor and cycle starts over again.
