How long Does an AC Unit Last?

New air conditioning units can last between 15-20 years, and older air conditioners last around 10-20 years on average, though the life of the unit also depends on the maintenance and regular cleaning of the unit been done in the past. An Amana high efficiency unit installed by AVS Heating and air comes with 10 years on all HVAC parts and limited life time warranty on the compressor.
