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 3 – Gas flows into the condenser, which dissipates heat. 4 – Refrigerant leaves condenser as a cool high-pressure liquid. 5 – Line set connects condensing unit to evaporator on top of the furnace. 6 – Liquid enters evaporator, which drops the pressure. 7 – It’s now a cool low-pressure gas. 8 – Blower fan distributes cooled air throughout ductwork. 9 – Hot air in room rises and is sucked into return vents. 10 – Vents circulate it back over the evaporator coil. 11 – Gas is sent outside to compressor and cycle starts over again.
