Repair or Replace? How to Decide
This is one of the most important home decisions you'll make. Here's how to think about it.
The age rule
- Under 10 years: usually repair
- 10-15 years: it depends on the repair cost
- Over 15 years: usually replace
The 50% rule
If a repair costs more than half the price of a new system, replacement is usually smarter.
Other factors
- Frequent repairs add up fast
- R-22 (old refrigerant) systems are costly to service
- A new high-efficiency system can slash energy bills
- Comfort and humidity control improve dramatically
