Should You Repair or Replace Your AC in Arizona?

When an air conditioner fails in the middle of an Arizona summer, the first question is how fast it can be running again. The second is whether it’s worth fixing at all. Here is how we help East Valley homeowners make that call.

Start with the age of the system

Arizona heat is hard on air conditioners. Systems here run for most of the year, often at full load for hours on summer afternoons. Many reach the end of their useful life sooner than they would in a milder climate. If your system is 10–15 years old or more, a major repair deserves a second look.

Check the refrigerant

Systems installed before about 2010 often use R-22 refrigerant. R-22 is no longer produced in the US, so the supply is limited and recharges are expensive. If an R-22 system has a leak, the repair keeps paying for refrigerant that is only getting scarcer. That usually tips the decision toward replacement.

Look at the repair history

One repair on an otherwise healthy system is normal. Repairs every summer are a pattern. Add up what you’ve spent in the last two or three years and compare it with the cost of a new system. When the repairs keep coming, the money is better spent on equipment that won’t need them.

Which part failed

• Usually worth repairing: capacitors, contactors, fan motors, thermostats, clogged drain lines, minor refrigerant leaks on newer systems.
• Often a reason to replace: a failed compressor or a leaking evaporator or condenser coil on an older system, especially one that uses R-22.

Efficiency and comfort

New systems are rated by SEER2. A newer, higher-efficiency system uses less electricity to move the same heat, and in Arizona that difference shows up on every summer bill. Two-stage and variable-speed systems also hold a steadier temperature and pull more humidity out during monsoon season. If some rooms never cool down, replacement is also the time to fix ductwork and sizing problems.

How we handle it

When we find a major problem, we give you the repair price and a replacement option side by side, and explain what each one gets you. You decide. If repair is the sensible choice, we’ll tell you that.
