When your Tucson, AZ, air conditioning system needs to be replaced, you’ll hear a lot about air conditioner compressor options. The compressor is a big part of an AC installation. Read on to find out how the compressor fits into the cooling system, how it works and why it’s important.

Know the Parts of an Air Conditioner

Central cooling systems have a compressor, condenser and evaporator. In a split system, the evaporator and air handler are inside, and the compressor and condenser are paired in the outdoor unit. The compressor is the go-between for the evaporator and condenser. Together, these parts create a closed-loop system that allows the compressor to move heat energy from your home to the outdoors.

Discover What the Compressor Does

Air conditioner compressors handle the chemical refrigerant twice. The compressor accepts the warm refrigerant that transfers heat from your home to the outdoors. At this point, the refrigerant is in a vapor stage. It compresses the refrigerant, allowing it to release its heat through the outdoor unit’s fins. The compressed refrigerant is cold and liquid. The compressor feeds the cold refrigerant into the evaporator’s coils. The warm air passes over the cold coil, transferring its heat and moisture. When the refrigerant absorbs the heat, it turns back into a vapor. It returns to the compressor. This completes a cooling cycle.

Understand Why the Compressor Is Important

Many times, an AC compressor failure requires a new air conditioning installation. The compressor is costly to replace, and it has to be matched with the condenser and evaporator for optimal performance. The air conditioner can’t cool your home if the compressor malfunctions or fails, explains the Department of Energy. Routine preventive maintenance helps you avoid most compressor issues. Compressors should operate quietly, but if you hear buzzing or rattling, it’s time for a service call.
