Not only do repeat failures take away from the contractor’s profit margin, they also tarnish a company’s professional image. Finding the cause and repairing it not only keeps the customer happy, it keeps the contractor profitable.

Just as the human body must be regularly checked to ensure the heart is working properly, so, too, must HVAC equipment. 

Should a compressor fail, the entire system will fail, and knowing how to properly test, diagnose, troubleshoot, and maintain that equipment will ensure minimal downtime while preventing future failures.

Bob and Tim were on their way to a no cooling call. The spring season was still cool at night and warm in the daytime. The customer told the dispatcher, “The unit started up at about 10:30 a.m. this morning and made a noise, but did not cool the house, even though it is still running.”

Compressor overheating is usually caused from high compression ratios. High compression ratios can be caused from a combination of high condensing pressures (temperatures) and low suction (evaporating) pressures.

Determining that a compressor has failed on a refrigeration system is normally a relatively simple procedure. But, discovering why the original compressor failed may not be as simple. 

With the compressor being such a critical element to a system, proper maintenance and repair becomes crucial to compressor and system longevity. But, equally important is correctly diagnosing the problem, ensuring that the problem lies with the compressor.
