AfterHow Much Does AC Repair Cost in Pasadena?
Most AC repairs in Pasadena run between $150 and $650, with the final number driven by the part that failed, how accessible your unit is, and whether you need refrigerant added on top of the mechanical fix. A simple capacitor swap typically lands near the low end at $150 to $250, while a compressor or evaporator coil job can push past $1,000 in some cases. We give you the exact price in writing before any work starts, so the number you approve is the number you pay.
At Dalton Heating & Air Pasadena, we’ve been repairing air conditioners across the San Gabriel Valley since 2003. Our techs are factory-trained on nine major brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. That matters because a York and a Daikin fail differently, and the fix is not always interchangeable.

AC Repair Cost Breakdown (2026)
Here is what we are charging across Pasadena in 2026, based on the jobs our technicians run every week:
| Repair Type | Typical Cost Range (Pasadena, 2026) |
|---|---|
| Capacitor replacement | $150 – $250 |
| Contactor replacement | $150 – $280 |
| Condensate drain line clearing | $120 – $220 |
| Thermostat replacement (basic) | $180 – $350 |
| Condenser fan motor replacement | $300 – $550 |
| Blower motor replacement | $350 – $650 |
| Refrigerant leak repair + recharge | $400 – $900+ |
| Evaporator coil replacement | $900 – $1,800 |
| Compressor replacement | $1,200 – $2,500 |
A few notes on these numbers. The capacitor is the part that gives the compressor its starting jolt. It fails most often during Pasadena heat waves, because sustained 100-degree afternoons push the part past its service life. The $150 to $250 range covers the part, the labor, and the trip out. The contactor, which is the electrical switch that tells the outdoor unit to turn on, sits in the same ballpark and often needs replacing at the same time as the capacitor.
On the higher end, a compressor replacement is a half-day job or more. The compressor is the pump inside the outdoor unit that circulates refrigerant. When it fails, the question becomes whether the system’s age justifies the spend. We will tell you straight if a replacement unit makes more sense than a major repair, and we never push a new install when a repair will honestly hold.
Refrigerant pricing deserves its own note. R-410A, the refrigerant used in systems built before 2023, has gone up sharply as manufacturers phase it out. A leak repair plus recharge can range widely depending on how many pounds your system needs and where the leak sits. The $400 to $900+ figure reflects a standard residential unit losing two to six pounds of R-410A. Newer systems running R-32 or R-454B are cheaper to recharge, but the leak still needs to be found and fixed first. Adding refrigerant without repairing the leak is a temporary patch, and it is not work we will do without flagging the real issue.
What Affects AC Repair Pricing in Pasadena
Several factors move the price up or down, and most of them are specific to this market:
- Parts availability by brand. Carrier and Lennox parts are usually stocked locally or within a day in Pasadena. Some Goodman and Rheem repair parts run cheaper, but availability has been inconsistent since 2024. When we quote a repair, the price reflects what the part actually costs us to source that week.
- System age. A 2018 Trane still has active parts inventory and straightforward wiring. A 2004 unit may need a discontinued control board sourced from a specialty supplier, which adds $80 to $150 to the job.
- Access difficulty. Plenty of Pasadena homes, especially in Bungalow Heaven and the Craftsman districts around Caltech, have AC units squeezed into closets, attics, or side yards with narrow clearance. If we need an extra hour to work around framing or old ductwork, that labor shows up in the quote before we begin, not after.
- Refrigerant type. As covered above, R-410A now costs more per pound than the newer R-32 or R-454B refrigerants. Older systems on R-22 are effectively obsolete; the refrigerant is no longer produced, and if we can source it, the per-pound price is punitive. In most cases, an R-22 leak is the point where we recommend replacement rather than repair.
- Time of year. AC repair demand in Pasadena spikes between July and October. Our pricing stays consistent year-round because we quote written prices by the job, not by supply and demand. But parts suppliers occasionally add surcharges during extreme heat waves, and those pass through transparently on the quote sheet.
- System type. A ductless mini-split repair runs different numbers than a central split system. Ductless requires opening the indoor unit, which adds labor. A packaged unit on a roof is its own category; rooftop access in neighborhoods like San Rafael and Annandale often means a ladder and a second tech, which we build into the written price upfront.
How to Save on AC Repair in Pasadena
The biggest savings come from catching problems before they become compressor failures. Here is what actually keeps money in your pocket:
- Replace your filter on a real schedule. During Pasadena summers, a 1-inch filter needs changing every 30 to 60 days. A clogged filter chokes airflow, which causes the evaporator coil to freeze, which then causes the compressor to work against a wall of ice. A $15 filter prevents a $400+ repair. This is the single cheapest insurance policy in HVAC.
- Keep the outdoor unit clear. The condenser needs 18 to 24 inches of clearance on all sides. Bougainvillea, ivy, and loose debris block airflow and force the system to run hotter. Trim vegetation around the unit before the season. If you have not cleaned the coil in years, a $250 service call now beats a $600 motor replacement later.
- Do not ignore the small signs. A faint hiss near the indoor unit, a 15-minute runtime that used to be 45, a slight hum that was not there last month. These are the early indicators of leaks, failing capacitors, and dying motors. Repairing at the $200 stage is always cheaper than repairing at the $900 stage.
- Get a fall tune-up at the tail of the season. The off-season tune-up in November or December runs $80 to $200 and catches the wear items before they harden into failures. It also guarantees your system is ready when that first 90-degree week hits in April.
- Ask for the price in writing before you approve anything. This one sounds obvious, but in this market it is not. Many Pasadena homeowners have been quoted one number over the phone and handed another at the door. Our rule is simple: the written quote is the price. If the job requires more work than the quote covers, we stop, explain, and get your sign-off before proceeding. You are never pressured into surprise charges mid-repair.

FAQs – AC Repair Cost in Pasadena
Is it cheaper to repair or replace my AC unit in Pasadena?
A helpful rule of thumb: if the repair costs half or more of what a replacement would, and the unit is over 12 years old, replacement usually makes better financial sense. As an example, a $1,600 compressor job on a 15-year-old Goodman is a losing bet compared with putting that money toward a new system. But a $250 capacitor on a 7-year-old Trane is a no-doubter. We walk you through the math on every job, and we never upsell a replacement when a repair will honestly do. Call (626) 657-5344 with your system’s age and symptoms, and we will give you an honest read.
How much does a capacitor replacement cost in Pasadena?
A capacitor replacement in Pasadena runs $150 to $250, including the part, labor, and the service call. It is the most common AC repair we handle, especially during July and August heat waves. The fix takes under an hour in most cases, and if the job requires anything beyond the capacitor, the written quote will reflect that before we proceed.
Can you come out today?
Yes. Our Pasadena team runs same-day service calls for most AC repairs, and our phone line is answered by a live person around the clock. Call (626) 657-5344 and tell us what the unit is doing. We will give you a service window, and the technician who shows up will be in uniform and background-checked, with a photo you can verify before they arrive.
Does Dalton Heating & Air charge by the hour or by the job?
We quote by the job, not by the hour. Every repair gets a written price before any work begins, and that price covers the part, the labor, and the trip out. You will never see a line item for “miscellaneous labor” or an hourly rate that creeps up while the tech is on site. The quote is the price.
What if the repair fails after you leave?
It is covered. Every repair we do carries a written guarantee for a full year. If the same issue returns in that period, we come back and make it right at no charge. It is part of the 365-Day Done Right Promise, and it is the reason we do the job correctly the first time.
Do you service all AC brands?
Yes. Our technicians are factory-trained on Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. If your Pasadena home runs a different brand, call us anyway; the fundamentals carry over, and we will tell you straight if we are the right crew for the job.
How much does a full AC installation cost in Pasadena?
A full AC installation in Pasadena runs $3,500 to $7,500 depending on system size, efficiency rating, and whether ductwork needs modification. That is a different service from a repair; see our AC Repair in Pasadena page for the repair side, and call (626) 657-5344 to talk through installation numbers.
