The compressor is often compared to the heart in a human body — a vital organ that must keep pumping for the entire system to function. Just as the human body must be regularly checked to ensure the heart is working properly, so, too, must HVAC equipment. Or, in the words of Scott Pires, a service technician with Welsch Heating & Cooling, St. Louis: “Have it cared for.”
Another analogy commonly used to explain the importance of the compressor is to compare it to an engine in a car. To keep both the heart and engine running, overall system health must be maintained.
