Most AC repairs in Los Angeles County cost between $150 and $650 in 2026, and the average lands around $400. That covers the common stuff, like a bad capacitor, a clogged drain line or a thermostat swap. Bigger jobs cost a lot more. A new compressor or evaporator coil can run $1,500 to $3,500.
What broke and how old the unit is decide most of the bill. A dead capacitor on a 6 year old system is a fairly cheap fix. Low refrigerant on a 16 year old system that still uses R-22 is a whole other story. The prices below come from Angi’s local data and a handful of LA contractor guides, so treat them as ballpark figures. Your own quote could land a bit above or below.
Average AC Repair Cost in Los Angeles County
Los Angeles County numbers for HVAC repair run from $148 to $2,272, with an average near $400. A drain line cleaning and a compressor replacement both count as AC repair, and they’re nowhere near each other in price.
Labor is a big chunk of it. Local technicians charge about $100 to $150 an hour, and most add a service call fee of $89 to $149 in normal hours just to come out and look. LA also runs a little above the national average since labor and living costs are higher here.
| Type of Charge | Typical Cost in LA County |
|---|---|
| Service call or diagnostic fee | $89 to $149 (daytime), $150 to $250 (after hours) |
| Simple repair (capacitor, contactor, thermostat) | $150 to $450 |
| Mid-range repair (refrigerant leak, blower motor) | $400 to $1,500 |
| Major repair (coil or compressor) | $900 to $3,200 |
| Yearly AC tune-up | $100 to $200 |
Heads up: Plenty of companies take the service call fee off the final bill if you approve the repair the same day.
AC Repair Cost by Problem
Capacitors are the one you’ll hear about most. They’re cheap, and they tend to fail on systems that are 7 to 12 years old. A compressor is the opposite. The part is expensive and the labor adds up, which is why people with older units often start pricing a whole new system instead.
Refrigerant leaks sit in the middle. If your AC is blowing warm air, low refrigerant (most people still call it Freon) is one of the usual suspects, and the fix depends on where the leak is. A loose fitting is quick. A leak in the evaporator coil usually means a new coil. Units that still run on R-22 cost the most to recharge. Production and imports of it ended in the U.S. in 2020, so what’s left keeps getting pricier.
| Repair | Typical Cost in LA | Notes |
|---|---|---|
| Drain line cleaning | $100 to $200 | Clears clogs that cause water leaks |
| AC capacitor replacement | $150 to $400 | Common on 7 to 12 year old systems |
| Blower motor | $400 to $900 | Worth fixing on newer systems |
| Refrigerant leak repair and recharge (R-410A) | $400 to $1,500 | Price depends on where the leak is |
| R-22 recharge | $800 to $2,500+ | Goes up every year |
| Evaporator coil | $900 to $2,200 | Lots of labor |
| Condenser coil | $900 to $2,500 | Sometimes ends in a new outdoor unit |
| AC compressor replacement (out of warranty) | $1,800 to $3,200 | Compare it with a new system on older units |
Watch out: A very low quote over the phone can leave out fees. Ask if it covers labor and the service call.
What Changes Your AC Repair Bill
- Older units cost more to fix because parts get harder to find. A 15 year old system usually needs more attention than a 5 year old one.
- Refrigerant matters too. R-410A is still the common one, and newer systems use A2L refrigerants like R-454B, which can cost more. R-22 is the expensive one.
- Evenings and weekends usually add a fee, often $150 to $250 just for the visit. If your AC quits at night, look for a 24-hour emergency HVAC service that tells you the after-hours fee up front.
- A unit on the roof or in a cramped attic takes longer to reach, and longer means more labor.
- A parts warranty can cover a compressor, but you still pay the labor, which runs $800 to $1,500.
Should You Repair or Replace Your AC?
There’s a rule most technicians use. If the repair costs more than half of what a new system would, replace the system. Many put the average AC replacement in Los Angeles at about $7,400, with most jobs between roughly $4,800 and $10,100. So a $3,000 compressor job on a 15 year old unit doesn’t make much sense.
Age counts too. Once a system passes 12 to 15 years, repairs start showing up more often. If you’ve already paid for two repairs in the last couple of years, the next one probably won’t be the last. People in that spot usually get an AC replacement quote to compare against the repair bill.
| Your Situation | Usually the Better Move |
|---|---|
| Small part failed, unit under 10 years old | Repair |
| Repair is under 50% of a new system | Repair |
| Major part failed on a 12 to 15 year old unit | Get a replacement quote |
| Two or more repairs in the past two years | Get a replacement quote |
| System still uses R-22 refrigerant | Replace |
Rule of thumb: If a repair is over 50% of a new system's price, start comparing replacement quotes.
Ways to Keep AC Repair Costs Down
- Rule out the simple stuff first. A dirty filter or a tripped breaker is behind a lot of “AC not cooling” calls. Weak airflow has other causes too, and this post on why an AC barely blows air goes through them.
- Change the filter every 1 to 3 months. A basic AC filter replacement costs far less than any repair. Higher MERV filters catch more dust but can restrict airflow on some systems, and this comparison of MERV 8, MERV 11 and MERV 13 filters shows what each one catches.
- Book a tune-up before summer. A summer maintenance visit checks the refrigerant level and cleans the condenser fan while it’s still mild out. Expect to pay $100 to $200.
- Get the problem diagnosed before you agree to parts. An AC system diagnostic finds the actual cause, so you’re not paying to replace something that was fine.
- Get two written quotes and compare the lines, including the warranty, along with the total.
What to Keep in Mind Before Your Next AC Repair Call
AC repair cost in Los Angeles County mostly lands between $150 and $650, and a handful of big jobs go past $2,000. What broke and how old the unit is decide most of it. Get the quote in writing, ask about the diagnostic fee, and if the number gets close to half the price of a new system, compare replacement before you say yes.
