Signs It’s Time to Replace Your AC Unit

Is your current air conditioner still worth repairing? Use the “$5,000 Rule”: multiply your unit’s age by the estimated repair cost—if it exceeds $5,000, it’s time to consider replacement. Look for these common indicators:

Your system is 10–15+ years old.
It breaks down frequently.
Your energy bills are steadily increasing.
Inconsistent room temperatures.
Strange sounds like grinding or squealing.
It uses R-22 refrigerant (now phased out).
