Signs HVAC system needs replacement are easy to miss — especially when it still runs. Many homeowners pay for repeated repairs on a system that should have been replaced years ago.
Signs That Point Toward Repair
- System is under 10 years old
- Isolated component failure (igniter, capacitor, thermostat)
- Repair cost under 30% of system's current value
- Energy bills haven't changed significantly
Signs That Point Toward Replacement
- System is 15+ years old
- Two or more significant repairs in the past two years
- Repair estimate exceeds 50% of what a comparable new system costs
- Energy bills climbed 15–20% without usage change
- Inconsistent comfort despite repairs
The Sign Most Homeowners Overlook
R-22 refrigerant. If your AC uses R-22 (Freon), phased out in 2020, you're in replacement territory. It's scarce, expensive, and getting more so every year.
The Compressor Test
Failed compressor on a 12+ year old system = almost always replace. Compressors cost $1,500–$2,500 — money better applied toward a new unit with a warranty.
How to Get an Honest Answer
Ask any HVAC technician to give you both options — repair cost and replacement cost — in writing.
