How Do You Know When It’s Time to Replace Your AC Unit?

An AC unit is a valuable investment, and every 15 to 20 years it will be time to reinvest and replace your AC unit. Recognizing the signs of replacement will make the difference between a smooth transition and a panicked emergency replacement:

Blowing Hot Air

An air conditioner should cool the home at a consistent temperature. If you experience inconsistent temperatures or hot air, it might mean low refrigerant levels or more serious issues like a damaged compressor. Either situation warrants a visit from a professional.

Unusual Noises

AC systems at peak performance are almost silent. There might be some slight noise, but nothing distracting. If the unit is emitting grinding, screeching, buzzing, rattling or ticking noises, it might be time for replacement.

Unusual Smells

An air conditioner should not smell. If you notice an unpleasant odor emanating from the unit, it might indicate damaged insulation or moldy ductwork.

Mold, dirt or mildew in the unit can enable contaminated air to circulate in the home. These smells should not be ignored.

Age

Some things get better with time, but your air conditioning unit is not one of them. The average lifespan will be about 15 to 20 years.

Age will affect the efficiency and performance of your unit. An older system may appear to run perfectly, but time will still affect it.

Replacement is an opportunity to upgrade with technological improvements, since newer units typically give better results at a lower cost.

Cost of the Repair

Regular maintenance and repairs are to be expected of any unit, but at some point, a repair might be more trouble than it is worth. Units should be serviced once a year, and multiple repairs in a year might indicate the need for replacement.
