There are a few different things HVAC contractors can check to ensure proper compressor function. This article highlights seven of them.

One of the worst enemies of a compressor is liquid refrigerant, so technicians should make sure the refrigeration system has proper superheat in order to protect the compressor from damage that can occur from flooding or slugging.

Comprehensive troubleshooting can help technicians determine whether the compressor is working properly.

Even though the circulated refrigerant is the working fluid required for cooling, lubricant or oil is needed for lubrication of the compressor’s moving mechanical parts.

Inexperienced service technicians have a tendency to add refrigerant to a troubled system in order to remedy a problem. Because of this, many systems are operating with an overcharge of refrigerant.

Airflow is one of the leading causes of failure for compressors.

The first step consists of determining the compressor’s mode of failure. Was it electrical or mechanical?

Any compressor that gets too hot or is overheated is subject to premature wear between its internal moving parts.

When electrically inspecting or troubleshooting a compressor, you should always protect yourself against the possibility of terminal venting.
