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.

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

Before servicing any refrigeration or air conditioning systems that contain an oil pump, technicians should make sure they understand the difference between net oil pressure and oil pump discharge pressure.

Have 166 years of small improvements and occasional leaps in chemistry taken us to the limit of what compressors can do?

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.

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.

Compressor manufacturers have been improving the products on multiple fronts in recent months.

Little by little, a compressor’s lubricating oil will eventually escape the compressor’s crankcase and enter the system’s tubing.
