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.
