Some people say that the compressor is the key component, or heart, of an air conditioning system. And like the human heart, the compressor must be kept in tip-top condition to run the system efficiently.
Both “organs” are difficult to maintain directly, since the heart is inside the body and the compressor, for the most part, is hermetically sealed. Like the human heart, the compressor depends on many parts connected to it. Circuits that carry electric current and airflow are vital to the compressor just like veins that carry blood are vital to the heart. And an overworked compressor, like a heart, will eventually wear out.
