AC Repair Los Angeles: $300 to $900 + Do This First (2026)

ConsumerAffairs' rows are Los Angeles prices; the rest are national. LA's capacitor range runs above HomeGuide's national $100 to $250.

Do this now: AC out in Los Angeles

1. Deal with the heat first. Above 90 F indoors, the CDC says a fan can raise body temperature, so move anyone at risk somewhere with air conditioning; dial 2-1-1 to find one.
2. Heat stroke signs (body temperature above 103 F, hot red dry skin, a fast strong pulse or confusion)? Call 911 first, Ready.gov says.
3. Ice on the copper lines or water on the floor? Set the thermostat to Off and the fan to On, and do not chip the ice. Bryant says thawing can take several hours.
4. Power out? Report it to LADWP at 1-800-342-5397, or to SCE if it serves your street. When power returns, reset the AC breaker once; if it trips again, leave it off.
5. Check the thermostat is on Cool, the filter is clean, and the outdoor unit has at least 2 feet of clear space (DOE).
6. Ask for the diagnostic fee before anyone comes: ConsumerAffairs lists $90 to $165 in Los Angeles.

Is it urgent? When an LA AC repair cannot wait

A dead AC is urgent in Los Angeles when a heat wave pushes the house past 90 F with someone at higher risk inside. Downtown averages 25.6 days a year at 90 F or hotter and 1.8 days at 100 F or hotter, NOAA's 1991 to 2020 normals show, and the August normal high is 84 F. Night and weekend labor costs $160 to $250 an hour in HomeAdvisor's 2026 data, against $75 to $150 in regular hours, so a unit that is only weak on a mild day can wait for a weekday.

• Call now: no cooling during a heat wave with an older adult, a baby or someone sick at home; heat stroke signs come first (911).
• Same day: water leaking from the indoor unit, a breaker that trips again, or a burning smell from the unit (shut it off).
• Can wait: weak cooling on a mild day or a noisy fan. The AC not cooling checklist covers what to try first.

Common AC repairs in Los Angeles and what they cost

A failed capacitor is the most common cheap fix, and ConsumerAffairs prices it at $220 to $440 in Los Angeles, above HomeGuide's national $100 to $250. A refrigerant leak repair and recharge runs $300 to $950 in LA. Compressors are the expensive repair: HomeAdvisor's national range is $1,200 to $2,800. When a compressor fails on an older system, compare the quote against a new system; ConsumerAffairs puts a full LA replacement at $7,400 to $15,000, covered on AC installation in Los Angeles.

Ask what refrigerant your system uses. The label on the outdoor unit lists it, and any technician who handles refrigerant must hold EPA Section 608 certification.

Power outages, wind and your AC

Wind events knock out power across Los Angeles. In the January 2025 windstorm and fires, about 92,000 LADWP customers and 314,000 SCE customers lost power at one point, and SCE's safety shutoffs hit 166,737 customers, Renewable Energy World reported. After the power comes back, check the thermostat and reset the AC breaker once before booking a visit.

Repair or replace: the permit side

A repair usually needs no permit, but a replacement does. LADBS lists "Replacing A/C units with same size & type" as an Express Permit, and the California Energy Commission says properly permitted work triggers any required HERS test, with HERS paperwork needed to close the permit. LADWP's October 2025 rebate sheet pays $300 per ton for a qualifying heat pump. For the hub of all heating and cooling topics, see HVAC repair in Los Angeles.

What to ask an LA AC repair company

1. What is the diagnostic fee, and does it go toward the repair?
2. What is your CSLB license number, and is it a C-20?
3. Is the technician EPA Section 608 certified?
4. Is the part under warranty, and what is the after-hours rate?
5. If the compressor is gone, what would a replacement cost with the LADWP rebate?
