Types of HVAC Compressors

Your HVAC system contains various parts that are at an elevated risk of jamming. One of these parts is the compressor. This compresses the refrigerant when it enters your machine to increase its temperature. The refrigerant then passes to your condenser where it cools the air.

The compressor works hard and can develop various electrical and motor issues. This complicated and fragile device requires expert AC repair in Gastonia. Here are the different types of compressors your repair expert might recommend replacing the broken one if it cannot be fixed:

Reciprocating Compressor

In this compressor, a piston is used to compress the refrigerant. Downward movement of the piston generates a vacuum effect that sucks in the coolant, while an upward movement releases it into the condenser. A reciprocating compressor may have one, two, four, or eight cylinders depending on its required output.

Scroll Compressor

This compressor has a stationary fixed scroll and an orbiting scroll that rotates and pushes a refrigerant into your condenser. The primary benefits of a scroll compressor are its quiet and smooth operation, less torque variation, and fewer moving parts. The minimal moving parts significantly decrease the instances of scroll compressor breakdowns.

Screw Compressor

This is an extremely efficient and reliable compressor but typically used in large buildings that require continuous cooling. A screw compressor has two large helical rotors that move the refrigerant through it. Refrigerant under low pressure enters from one end, and the pressure created by rotation of the rotors discharges it out through the opposite end into the AC’s condenser.

If your AC continually trips the circuit breaker, blows warm air, or makes strange noises, a failed compressor is the primary culprit. A vibrating outdoor unit might also signify compressor problems. The above compressors all make suitable replacements for an irreparable one.
