Air Conditioning Parts and Components

Some of the most essential air conditioning parts include the compressor, the condenser coil, and the evaporator coils.  There are also air filters, coil fins, contactor relays, time delay, and the compressor power pack.

The compressor is one of the hardest working central AC components.  It pressurizes the refrigerant causing it to turn into a vapor, and then pushes it toward the condenser. The condenser coil soaks up heat, where it becomes superheated, and the vapor is pushed into the condenser coil where the vapor hits outside air and all that heat is removed.

The evaporator coils takes over after that previous vapor turns back into a liquid.  The liquid hits the evaporator coils and mixes with hot air.  The refrigerant in liquid form soaks up moisture and heat and then condenses it, draining it from the system.  This leaves the air cooled.

Air filters keep unwanted particles, dust and debris from entering into the air conditioner and causing clogs in the system. Coil fins are a part of the evaporator and condenser coils and are essential to those AC parts properly functioning. Contractor relays control the fan and compressor, turning it on an off as necessary. Time delays will protect the contactor from any power surges which might occur, as well as creating a space between when the contractor turns on and off in order to prevent short cycling.

All of these are essential central air conditioning components that work together to keep your AC system running efficiently.  Let the Scottsdale, AZ air conditioning technicians at Cool Touch Air Conditioning, Heating, Plumbing & Electrical help with all your air conditioner repair and maintenance needs this summer.
