When your AC breaks down on a hot Sonoma County day, the pressure to make a fast decision can lead to the wrong choice. Here’s a simple framework for deciding whether to repair or replace — based on the actual numbers.
The Age-Times-Repair Rule
Multiply the age of your system (in years) by the repair cost estimate. The bigger that number, the stronger the case for replacement, and a seasoned technician can tell you where your system falls.
Strong Signals to Replace
- System uses R-22 refrigerant (phased out — very expensive now)
- Compressor failure (often not worth it on older systems)
- Multiple major repairs in the last 2 years
- System is 15+ years old and losing efficiency
- Home is uncomfortable despite AC running constantly
Strong Signals to Repair
- System is under 10 years old
- Repair is a simple component (capacitor, contactor)
- System was recently serviced and is in otherwise good shape
- You plan to sell the home in the next 1–2 years
The Hidden Factor: Energy Efficiency
An old, low-efficiency unit running on a dying compressor costs far more to run each month. Over the life of the system, those savings can fund the replacement and more.
