Air conditioners are designed to remove heat from the indoors, making your home comfortable and cool even during the hottest Surprise summer afternoons. If you have always wondered how air conditioners function, consider how these major components work together.


The compressor is the heart of your air conditioner. It’s designed to turn gas into liquid by converting low-pressure gaseous refrigerant from the AC’s evaporator into a high temperature and high-pressure gas before going through the condenser. The compressor is integral in this process, allowing the AC to cool down the warm air indoors to create a comfortable and cool home.

Drain Pipes

Drain pipes are an essential part of your air conditioning system because they collect water droplets after condensation when hot air is converted into cool air. They move the water droplets out of the air conditioner. Clogged or faulty drain pipes result in water leaks from your air conditioner.

Expansion Valve

Another major component of an air conditioner is the expansion valve that collaborates with the evaporator. The component is situated between the condenser and evaporator. The expansion valve plays a vital role in regulating the amount of liquid refrigerant moving into the evaporator to change into a gas.


Your AC’s thermostat is the center of the air conditioning process. It reads indoor temperatures and sends signals to the air conditioner regarding when to turn on or off. You can change temperature settings from the thermostat to suit your home’s unique needs.

Condenser Coil

The condenser coil of an AC system is attached to a fan. The fan is designed to cool down the gas coming in at high pressure. You can find the AC’s condenser coil on the outside of the system. It’s a crucial component of the system.
