When an AC stops cooling, the cost question comes right after the "what's wrong with it" question — and the honest answer is the same for both: it depends on the part. AC repairs across our service area typically run $129 to $1,200 installed (parts and labor), and a capacitor swap and a compressor replacement sit at opposite ends of that range for good reason.
This page breaks down what the most common AC repairs actually cost, what pushes a job toward the low end or the high end, and what's included when you book a Triton technician. If you're diagnosing a specific problem right now rather than researching cost, see AC Not Cooling / Blowing Warm Air or AC Condenser Fan Not Spinning. AC calls also spike hard on the first real heat wave of the year, so if your system has been struggling to keep up, it's worth getting it looked at before the next hot stretch rather than during it.
What AC repairs typically cost
| Repair | Typical Bay Area Cost |
|---|---|
| Capacitor | $120–$350 |
| Contactor | $120–$320 |
| Refrigerant leak + recharge | $180–$650 |
| Compressor | $900–$1,600 |
These are installed prices for the repair itself, confirmed on-site before any work starts. Refrigerant and compressor work sits at the high end of what an AC call can cost — everything else in the system (capacitors, contactors, sensors, low-voltage wiring) tends to be a same-visit, moderate-cost fix.
Most calls land well inside the $129–$1,200 range, not at either edge. A capacitor or contactor is close to our service-call floor; a refrigerant leak or a failing compressor is the bigger job.
What drives the price up or down
- Which part failed. A capacitor or contactor is a fast, inexpensive swap. Refrigerant work depends on finding and fixing a leak before recharging, and a compressor is the most expensive single part in the system.
- How much refrigerant the system needs. A small leak caught early costs less to top back up to spec than a system that's been running low for a while.
- Brand and part availability. Common parts usually ride on the truck; a less common brand or an older model may need a part ordered.
- Access to the outdoor unit or air handler. A condenser in an open side yard is quicker to service than one boxed in behind fencing or landscaping, and an attic air handler adds labor time versus one in a closet or garage.
- Age and condition of the system. An older AC that's low on refrigerant may also have early compressor wear, which changes the conversation from "repair this part" to "repair vs. replace."
- Whether the system uses R-410A or older R-22 refrigerant. R-22 has been phased out of U.S. production, so refrigerant and parts for older R-22 systems generally cost more to source than the R-410A equivalent — see our refrigerant recharge cost guide for more on that.
What's included when you book Triton
- A diagnostic visit that confirms the actual failed part, including a refrigerant pressure check — not a guess.
- The diagnostic fee is credited toward the repair once you approve the work.
- A flat, upfront quote before any part is replaced or any refrigerant is added — no surprise line items.
- Licensed, EPA 608-certified techs for any work involving refrigerant.
- Straight talk about whether a repair or a replacement conversation makes more sense given your system's age and the part that failed.
DIY or call a pro?
Capacitors hold an electrical charge, refrigerant lines run at high pressure, and only an EPA 608-certified tech can legally buy or handle refrigerant — this isn't a safe or legal do-it-yourself category past the basics. What you can check for free: change the air filter if it's dirty, confirm the thermostat is set to COOL below room temperature, and reset a tripped breaker once (if it trips again, stop and call). Clearing debris, leaves, or overgrown landscaping away from the outdoor unit is also safe and free, and it's one of the most common reasons an otherwise healthy system struggles to keep up on a hot day. Beyond that — capacitors, contactors, refrigerant, compressors — it's licensed-tech work.

Frequently asked questions
How much does AC repair cost in the Bay Area? Most AC repairs run $129–$1,200 installed depending on the part. A capacitor is typically $120–$350, a contactor $120–$320, a refrigerant leak repair plus recharge roughly $180–$650, and a compressor $900–$1,600.
What's the most common AC repair? Capacitors are the most common call — a small part that fails from normal wear and heat cycling, and one of the fastest, least expensive real fixes in AC service.
Why does refrigerant or compressor work cost more than a capacitor? A capacitor swap is a same-visit part replacement. Refrigerant work means finding and sealing a leak before recharging to spec, and a compressor is the most expensive, most labor-intensive part in the system — both take more time and more specialized (EPA-licensed) work than a capacitor or contactor.
Is it cheaper to repair or replace my AC? It depends on the system's age and what failed. A capacitor, contactor, or even a refrigerant leak on a newer system is almost always worth repairing; a failing compressor on an old, low-efficiency system is the point where it's worth asking your tech for a replacement quote alongside the repair quote.
Do you charge a diagnostic fee? Yes, but it's credited toward the repair once you approve the work, so you're not paying for the visit and the fix separately.
Do you offer same-day AC repair? Yes — we serve the East Bay, Tri-Valley, and Peninsula, including Livermore, with same-week and often same-day slots, which matter most during a heat wave. Call (888) 993-5699 to book.
