An air conditioner repair in San Jose usually costs $150 to $650, and a typical bill lands around $350. Where yours falls depends mostly on which part failed. A weak capacitor or a burned contactor is a small, quick job. A refrigerant leak or a failed fan motor needs more time and pricier parts. A dead compressor is a different conversation, covered at the end of this page.
Prices for common AC repairs
| Repair | Typical price | What you usually notice |
|---|---|---|
| Capacitor replacement | $150–$300 | Outdoor unit hums but the fan does not spin, or it will not start on a hot afternoon |
| Contactor replacement | $150–$350 | Outdoor unit stays silent, chatters, or keeps running after the thermostat is satisfied |
| Thermostat replacement | $150–$400 | Blank screen, wrong temperature, or the system ignores the setting |
| Evaporator coil cleaning | $150–$400 | Weak airflow, ice on the indoor coil or the copper line |
| Refrigerant recharge with leak repair | $250–$600 | Runs all afternoon, never reaches the setting, air at the vents only mildly cool |
| Fan motor replacement | $300–$650 | Fan slow, noisy or stopped; the compressor shuts off and restarts |
These figures describe typical jobs in San Jose homes. They are not quotes: the exact price comes after the system has been tested.
Why two bills for “the same repair” differ
The part and its refrigerant. A capacitor is a capacitor, but the fan motor for one system can cost far more than the motor for another. Systems that still run on R-22 refrigerant, which has not been produced or imported in the US since 2020, cost more to recharge because only recovered stock is left.
Age of the system. Parts for older units are often discontinued, so the technician fits a universal part, which takes longer. Older systems also tend to show more than one worn part on the same visit.
Part availability. Common capacitors and contactors ride on the truck. A model-specific motor may have to be ordered, which can mean a second visit.
Time of year. The first stretch of 90-degree afternoons brings a rush of calls from systems that sat idle all winter. A spring check avoids that week entirely.
Emergency or scheduled. Nights and weekends are usually priced higher than a weekday visit. If the house is only warm and nobody at home is at risk, a morning appointment is often the cheaper choice.
Refrigerant: the line to read twice
Refrigerant circulates in a sealed loop; the system does not consume it. If the charge is low, it leaked somewhere: at a flare fitting, a valve core, a copper line rubbing on the cabinet, or the coil itself. Adding refrigerant without finding the leak buys a few weeks or a season, and then you pay again. The $250–$600 range above assumes the leak is located and repaired. A leaking evaporator coil that has to be replaced is a bigger job and belongs to the repair-or-replace question below. Refrigerant is handled by EPA-certified technicians only.
Getting a firm price
- Call or book online and describe what the system does: no cooling, warm air, ice, water, noise, a tripping breaker.
- The technician tests before changing anything: capacitor and contactor, motor current, refrigerant pressures and the temperature drop across the indoor coil.
- You get the repair price before work starts, with no hidden fees, and you decide.
- If you go ahead, the diagnostic fee is waived.

When repair stops making sense
A compressor replacement typically costs $1,500 to $3,000, well above the usual repair range, and that is where the question changes. A useful rule: if a repair costs more than half the price of a new system and the system is over 10 years old, replacement usually makes more sense. Other signs point the same way:
- The system runs on R-22 and has a leak.
- It is the second or third significant repair in two summers.
- The house never cools on the hottest afternoons even when everything works, which can mean the system is undersized for the house or the ducts lose too much air in the attic.
Estimates for replacements are free. The repair-or-replace calculator walks through the numbers. If the furnace is old too, one heat pump can replace both; for a new air conditioner alone, see AC installation.
A note for San Jose homes
On the valley floor, summer afternoons often reach the 90s, and an attic gets far hotter than that. A capacitor that copes in May often fails in the first heat wave, and a dusty outdoor coil pushes the compressor hard every afternoon. In Evergreen many tract homes still run builder-grade equipment that is reaching replacement age, and in Blossom Valley some homes still have equipment around 40 years old, so the repair-or-replace question comes up there often. A spring maintenance visit cleans the coil and tests the capacitor and contactor before the heat arrives. If your unit will not start at all, see AC not turning on; if it starts and stops every few minutes, see AC short cycling.
