Decision Framework
The calculator applies these guidelines. Understanding them helps you evaluate any recommendation from a contractor.
| Factor | → Repair | → Replace |
|---|---|---|
| System age | Under 8 years | 15+ years |
| Repair/replacement ratio | Under 25% | Over 50% |
| Refrigerant type | R-410A / R-454B | R-22 + any leak |
| Compressor status | Functioning | Failed, system 10+ |
R-22 Warning
If your system uses R-22 (Freon) and has a refrigerant leak, replacement is almost always the right call. R-22 is no longer manufactured in the US, and recycled supply prices have made any meaningful refrigerant recharge expensive. A new system solves the problem permanently.
Orange County Replacement Cost Range
For the repair/replacement ratio calculation, typical installed replacement costs in Orange County run $5,000–$8,500 for a standard 2.5–3.5 ton central AC system. Premium efficiency units or difficult installations can run higher.
Repair vs. Replace: Common Questions
What is the 50% rule for AC repair vs. replacement?
If a repair costs more than 50% of the installed price of a comparable new system, most HVAC professionals recommend replacement. The logic: you're paying a significant fraction of a new system's cost to extend aging equipment that may fail again soon. The rule applies best to systems over 10 years old.
Should I repair my AC if it uses R-22 refrigerant?
Generally no, for repairs over a few hundred dollars. R-22 (Freon) was phased out of production in 2020 and now comes only from recycled supplies. Prices have risen sharply — $50–$100+ per pound — making any repair that requires refrigerant work expensive. A new system uses modern refrigerant that's widely available and affordable.
At what age should I replace my AC instead of repairing it?
Most HVAC professionals recommend replacement when a system is 15+ years old and has any major failure. For systems 12–15 years old, repair cost relative to replacement becomes the key variable. Under 10 years old, repair is almost always the right call unless the failure is catastrophic.
Is it worth replacing an AC before it completely fails?
Sometimes yes — especially if your system is 14+ years old and showing signs of decline (higher energy bills, uneven cooling, frequent small repairs). Replacing proactively in spring means you choose the timing and equipment, rather than making a rushed decision in July when companies are booked out 2 weeks.
