Compressor Failure Causes

5 reasons your compressor may quit

You always want your compressor to do well. It’s the heart and soul of your heating, ventilation and air conditioning system. Also, it’s the most costly piece to replace or repair.

But when the compressor quits doing its job at peak efficiency, you can expect the trouble usually will be rooted in one of these areas:

•Oil problems – Oil can contaminate the compressor if you have an oil leak, the oil pump fails, or oil gets trapped in a suction line. This leads to a lack of lubrication and an increase in friction.

•Refrigerant problems — Bad settings or too much refrigerant are a couple reasons why the liquid refrigerant stops vaporizing fully in the evaporator and starts putting too much pressure on the compressor.

•Electrical problems — The compressor can overheat and fail if there are imbalances in the current or the voltage.

•Dirt or other intruders – A system can be contaminated by dirt, air, moisture or acids created by heat and pressure.

•Overheating – A lack of cooling or an intrusion of air or non-condensable gases into the system can cause the compressor to overheat.

Two suggestions

One way to avoid these problems is to have Enviro Air conduct a periodic check. Our routine maintenance program often uncovers and corrects small problems before they become big, expensive-to-fix problems.

If your compressor already is doing badly, contact us at 855-420-COOL and we will gladly review your system and give you all the information you need to decide whether you should replace or repair the compressor.

A properly maintained HVAC system should function 15 years or more, but the life depends on such factors as sizing, daily run-time, maintenance and the history of repairs.
