When to Repair vs Replace Your AC
Trying to decide whether to repair or replace your air conditioner? In Phoenix, AC systems work harder than almost anywhere else, which means they wear out faster.
Repair may be the right option if:
- Your system is under 8–10 years old
- The air conditioning repair is minor or low cost
- Your AC still cools effectively
Replacement is usually better if:
- Your unit is 10–15+ years old
- You’re facing frequent repairs
- Energy bills are increasing
- Your home isn’t cooling evenly
The 50% Rule:
If repair costs are more than 50% of a new system, replacement is typically the smarter long-term investment.
