When problems occur with your air conditioning system, you may begin to worry that the AC system itself needs replacement. And often, an AC needs replacement because the compressor has gone bad. The compressor is one of the most critical and costly parts of your air conditioning system. So you want to maintain them as best as possible to prevent expensive repairs or even full system replacements. By having a routine, manufacturer suggested quarterly maintenance of your HVAC systems, you stand a better chance of catching failed components that may lead to a failed compressor.
