AC repair costs in the East Bay typically fall between $150 and $600 for most single-family homes. Here's what drives the range.

Common Repairs and Prices

Capacitor replacement: $250–$450
Contactor replacement: $200–$400
Thermostat replacement (basic): $250–$450
Smart thermostat install: $400–$700
Refrigerant top-up (R-410A): $300–$600
Fan motor replacement: $500–$900
Coil leak repair: $800–$1,800
Compressor replacement: $2,200–$3,800 (usually a replace-the-system conversation)

When Repair Turns Into Replacement

The 5,000 rule: multiply the repair cost by the system's age in years. Over $5,000 = replace. A $700 repair on a 10-year-old system? Fix it. A $700 repair on an 18-year-old system? Replace it.

Frequently Asked Questions

What is the most common AC repair?

Capacitor replacement. It's the small cylindrical part that starts the compressor. A weak capacitor causes about 40% of no-cool calls and runs $250–$450 installed.

Is it worth repairing a 15-year-old AC?

If the repair is under $500, yes. If it's over $1,500 — especially compressor or coil work — replacement is almost always the smarter move.

Do you charge for AC diagnostics?

Yes — a flat diagnostic fee that's credited against the repair if you approve the work same day. We give a written repair estimate before starting.
