Telltale Clues to Your Air Conditionerâs Life Span. 1  The A/Câs age â The average air conditioner life span is roughly 15 years. If yours is over 10 years old, you can expect to see a steady loss of cooling capacity and efficiency. Older equipment is more prone to breakdowns too, so necessary repairs are more frequent.
Our rule of thumb for age on A/C's is about 20 years is a good life span. Heat pumps are at about 10 years. If a unit is older than 20 years, you should upgrade to a new unit for better efficiency and reliability. I don't know what they are telling you about changing the air handler.I understand that the evap. coil may be to old, but that part is replaceable with the new condenser.wo part question here about AC unit: 1) My compressor/condensor is 12-years-old, and it is having problems. It was a &quot;builder&#39;s model&quot; that came with the house.
