Understanding the AC Compressor: The Heart of Your Cooling System Phoenix Air Conditioning Repair 24 7 Air Conditioning Service

The AC compressor is a mechanical pump that compresses refrigerant gas, increasing its pressure and temperature. This high-pressure, high-temperature refrigerant then flows through the condenser, where it releases heat and turns into a high-pressure liquid. The liquid refrigerant then travels to the expansion valve or orifice tube, where its pressure is reduced, causing it to cool significantly. Finally, the cold, low-pressure refrigerant flows through the evaporator coil, absorbing heat from the air blowing across it and cooling your home. 24 Hvac Service Near Me 24 7 Ac Service

In essence, the compressor is the driving force behind this entire cooling cycle. Without a properly functioning compressor, the refrigerant cannot circulate effectively, and the AC system will fail to cool your home. 24 Hour Emergency Air Conditioning Service Near Me 24 Hour Hvac
