HVAC Q&A: Can a 20-Year-Old AC Unit Be Repaired?

With regular preventative maintenance, it is possible to keep a hard-working air conditioning running for 20-plus years, even in the demanding desert environment and super-high temperatures common in Metro Phoenix.

Servicing an AC unit that is 15-, 20- or 30-years-old, however, may require more than just a motor replacement. Often older HVAC systems need extensive coil cleaning and complete tune-up regimens.

It is also important to remember that older AC units are much less efficient than modern high-efficiency HVAC systems with a higher SEER rate, which is the seasonal energy efficiency ratio. 

Here Kennie Hernandez, Lead HVAC Technician, Cool Aid Air Conditioning, opens the housing of an AC unit on the second story of a condominium at Villas Scottsdale, during a record-breaking 114-degree day, Aug. 19, 2020.
