When HVAC problems arise, many homeowners struggle with the question of whether to repair or replace their system. The debate of nursing a unit along to avoid an unexpected replacement expenses vs. taking care of the inevitable now instead of later is the subject of many dinner table discussions.

While we have seen well maintained AC units last as long as 15-20 years, the average AC unit, especially in a brutal climate such as Phoenix, has a life span of about 10 years.

Let’s look at some tips to help you decide if it’s time to repair or replace:

  • If your system is more than 10 years old, a major repair is not recommended. A system replacement usually makes more financial sense.
  • Older systems become less efficient over time, even when they’re running optimally. A new system will help you save energy.  Make sure to factor in your lowered energy bills when you’re doing your “repair or replace” analysis.
  • If you’re getting a lot of hot or cold spots, your system struggles to keep your home cool when it’s hot outside, or if it’s making strange noises or vibrations, it may be time to replace.

Residential air conditioning system repair costs can really add up when trying to save a failing unit. Plus, there continues to be a risk of the system locking up or shutting down despite the repairs.   It’s very much like making repair decisions on a high mileage car.  Do you change the transmission on a vehicle that has over 100,000 miles on it?  There are many variables that go into the decision and the goals of the family involved, same with a repair or replace decision for your AC unit.
