What Does an AC Compressor Do?

The air conditioning system relies on the AC compressor to effectively cool your space in the summer. It cools the air inside by pressurising and circulating refrigerant gas, which absorbs heat from inside and releases it outside. Low-pressure refrigerant gas is drawn from the evaporator by the compressor to start the process. The temperature and pressure of the gas significantly rise as it is compressed. When the high-pressure, high-temperature gas reaches the condenser, it releases heat and turns back into a liquid. The cooled liquid is sent back to the evaporator, and the cycle repeats, maintaining a comfortable indoor temperature.
