Most AC repair bills in San Leandro come down to one question: which part failed? A capacitor and a compressor are both “AC repairs”, but they sit at opposite ends of the price scale. Below are typical ranges for the repairs we see most, what each one involves, and what moves a job up or down within its range. You get the exact price for your system before any work starts.
Typical AC repair costs
| Repair | Typical range |
|---|---|
| Capacitor replacement | $150–$300 |
| Contactor replacement | $150–$350 |
| Fan motor replacement | $300–$600 |
| Refrigerant recharge (R-410A) | $200–$400 |
| Refrigerant recharge (R-22) | $400–$1,000+ |
| Evaporator coil repair | $400–$1,000 |
| Compressor replacement | $800–$2,500 |
| Thermostat replacement | $150–$400 |
These are estimates. The actual cost depends on your system and on what the diagnosis finds, and you see the price before the technician starts.
What each repair involves
Capacitor and contactor. These two electrical parts in the outdoor unit fail more often than anything else. A weak capacitor leaves the fan or the compressor humming without starting; a worn contactor keeps the outdoor unit from switching on, or keeps it running when it should stop. Both are usually replaced in one visit, which is why they sit at the low end.
Fan motor. The outdoor fan pulls air through the coil to carry the heat away. When the motor fails, the system overheats and shuts down on warm afternoons. The price depends on the motor type and whether the blade or the capacitor is replaced with it.
Refrigerant recharge. Refrigerant does not get used up, so a low charge means a leak somewhere. A recharge puts the system back in service, but the problem returns. Finding and fixing the leak costs more, with refrigerant leak repairs generally running $500–$1,500, and it lasts. The refrigerant type matters a lot: R-410A costs far less to recharge than R-22, which has not been produced in the United States since 2020.
Evaporator coil repair. The indoor coil sits on top of or next to the furnace or inside the air handler, and older coils develop leaks. On an older system, especially one on R-22, a leaking coil is often where the repair-or-replace question begins.
Compressor replacement. The compressor is the most expensive part of the system, and the range is wide because the size, type and labor vary. On a system past 10 to 15 years, put this price next to the cost of a new system before deciding.
Thermostat replacement. A failed thermostat or a loose wire can look like a dead air conditioner. The price depends mostly on the thermostat you choose.
What moves the price
Type of repair: the biggest factor. A capacitor at $150–$300 and a compressor at $800–$2,500 are both common repairs. Nothing else moves the bill as much.
System age: moderate. Older systems can need parts that are discontinued or harder to find, and diagnosis takes longer. Systems over 15 years old tend to cost more to repair.
Brand and model: moderate. Parts for premium brands such as Carrier, Trane and Lennox can cost slightly more. Older or discontinued models may need special-order parts.
Refrigerant type: moderate. Systems on R-22 cost much more to recharge than systems on R-410A.
Access. An evaporator coil in a cramped attic or crawlspace takes longer to reach and work on than one in a garage or hall closet.
Timing: minor. Emergency and after-hours service can cost more than a scheduled visit, so if the repair can wait, book it during regular hours.
Repair or replace?
As a rule of thumb, if a repair costs more than half the price of a new system, or the air conditioner is over 12 to 15 years old and needs a major repair, replacement may be the better long-term choice. An R-22 system with a refrigerant leak is the clearest case. Our AC repair vs replacement page walks through the decision, and the HVAC installation cost guide shows what new equipment typically costs.
How to keep AC repair costs down
- Book a yearly tune-up. AC maintenance catches weak capacitors, dirty coils and clogged drains before they turn into no-cooling calls.
- Change the filter. A clogged filter starves the indoor coil of air and can make it freeze.
- Keep the outdoor unit clear. Plants, leaves and lint packed against the coil make it work harder on warm days.
- Ask about replacement before a major repair on an old system.
- Plan an R-22 replacement before an expensive refrigerant repair forces the decision.
- Compare quotes. We will beat any written quote.
How our pricing works
A technician diagnoses the system and gives you the repair price before any work begins, with no hidden fees. The diagnostic fee is waived when you go ahead with the repair, repairs carry a 90-day warranty, and replacement parts keep the manufacturer’s parts warranty. Seniors and military households get 10% off; ask when you book.
Timing in San Leandro
Air conditioners here often sit idle for months, then run hard through warm spells in late summer and early fall. That is when weak capacitors and dirty coils give out, and when schedules fill up. Catching a weak capacitor at a spring tune-up is easier than replacing it on a hot afternoon. If your system has already stopped, see AC not cooling or book AC repair; same-day service is usually possible when you call before noon.
