The heart of both an electric refrigerator and an air conditioner is the compressor, its most costly component. No other electromechanical device comes close to the reliability of the semi-hermetic or fully hermetic compressor.

Consider the following comparison.

  • On average, the compressor operates in a refrigerator at full speed almost half the time. That is about 4,000 hours out of 8,760 hours in a year.

  • In 15 years, that would be 60,000 hours.

  • If your automobile operated 60,000 hours at only 50 miles per hour that would be 3 million miles!

  • That is 120 trips around the world at the equator, or 6 round trips to the moon.

  • The compressor does this without a valve job, new points, new plugs, or even an oil change.

  • Unless the compressor has a problem, neither lubricating oil nor refrigerant are added over the 15, 20, or even 30 years that many compressors operate.

  • Search your mind. Can you think of any other electromechanical device with a comparable record of reliability and operating life?

  • The next time someone says that they don't make things to last as long as they used to, consider the compressor.

  • The majority of compressor failures are not due to the compressor, but rather to a system problem that caused the compressor to fail. It is important to determine the cause of a compressor failure when replacing a defective compressor or the replacement compressor is bound to fail as well. Don't be too quick to blame a failed compressor on the compressor itself.

  • Learn the causes of compressor failures and make it a habit to check the system for the potential cause of a compressor failure.
