When an older air conditioner breaks down, the first question is often whether to fix it or replace it. There is no single right answer. These are the questions that help you decide.
Questions about your current system
How old is it? The age is usually on the label of the outdoor unit, or in the serial number. Systems in Arizona work hard, so age matters. An older system that needs a major part is a different decision from a newer one that needs a small repair.
What does the repair cost, and what does it fix? Ask what failed, why, and whether anything else is close to failing. A clear explanation is worth more than a quick number.
How often has it needed repairs? One repair in ten years is different from three in two summers.
What refrigerant does it use? Many older systems use R-22. The EPA ended production and import of R-22 in 2020, so it is now scarce and expensive. A large refrigerant leak on an R-22 system often tips the decision toward replacement.
Is the house comfortable? Rooms that never cool down, high humidity or big swings in temperature can point to a system that is the wrong size or ductwork that needs work.
If you are looking at a new system
Ask how the size was chosen. A new system should be sized for your home, not just matched to the old one. Square footage, insulation, windows and sun exposure all affect how much cooling a home needs. A system that is too large or too small can run poorly and wear out sooner.
Understand the efficiency rating. Air conditioners and heat pumps are rated by SEER2, which measures cooling efficiency over a season. A higher number uses less electricity for the same cooling. Federal rules set minimums, and Arizona falls in the Department of Energy’s Southwest region, which has its own requirements. Ask what rating you are being quoted and what it costs to step up.
Ask what refrigerant the new system uses. Refrigerant rules for new equipment have been changing. A good contractor can explain what your new system uses and what that means for future service.
Get it in writing. A written estimate should list the equipment, what is included in the installation, and how the manufacturer’s warranty is registered.
Get a second opinion on big decisions. One of our customers wrote that another company told them to replace their upstairs unit right away. A second look kept it running for a few more years. Replacement was still the right call later, but on their schedule.
