The compressor is the lifeblood of a commercial AC and the life expectancy of compressors in commercial HVACs is up to 15 years if you maintain them properly.

A compressor of a well-maintained HVAC could provide many years of service. 

However, if you fail to maintain your commercial HVAC, the life of the compressor may reduce to 8-10 years. You must schedule commercial HVAC maintenance once a year to get the expected results from compressors.
