The compressor is the heart of an air conditioning system. It’s the component that puts refrigerant under pressure so it will circulate and carry out the process of heat exchange that cools down a home. Without a working compressor, a central air conditioner is nothing more than a large central fan.
The compressor is also an expensive component to replace if it fails. The conventional wisdom is that when an AC’s compressor burns out, the best option is to have a new air conditioning system installed rather than pay to put in a new compressor. Is this true, and is it always the case? We’ll look at this more below.
