Understanding The Basics Of Ac Operation

An air conditioning system cools your home by a process. The refrigerator cycle is this process. Key parts include the compressor, condenser, evaporator, and expansion valve. The compressor pumps refrigerant through the system.

The refrigerant captures heat inside the house. This heat transfers outside by the condenser. Next, the refrigerant cools down. The evaporator uses cool refrigerant to chill air. The expansion valve controls the refrigerant flow. These steps repeat to keep air cold.
