AC Repair
homes that need diagnosis before anyone pushes a full replacement
Same-day priority during heat waves
No-cool AC call in Los Angeles — what to check before booking.
Use the safety checklist below in the first five minutes. Then call +1 (213) 755-2539 and describe what is happening so the dispatcher can route the right technician with the right tools.
First 5 minutes
Safety steps before the technician arrives.
- Confirm the thermostat is set to cool and the temperature target is below room temperature.
- Check the air filter — a clogged filter can freeze the evaporator coil and stop airflow.
- Listen for the outdoor condenser; if it is silent, do not keep resetting the breaker. The compressor may be locked.
- Note whether one room or the whole home is hot. A single hot room usually points to duct, return, or zoning issues, not the condenser.
- Document when the symptom started (after heat wave, filter change, smart thermostat install, power outage, remodel).
Diagnostic field checks
What the technician runs on arrival.
- Capacitor test (microfarad reading vs. nameplate)
- Compressor amperage on start
- Refrigerant subcool / superheat balance
- Return-air static pressure
- Disconnect & breaker condition
- Thermostat wiring and call confirmation
Cost expectation
Typical pricing range.
Diagnostic visit $125 / repair labor $185 per hour / capacitor replacement $185-$320 / refrigerant adjustment $350-$800 / replacement quote $7,500-$18,500.
Final cost depends on field findings. The visit produces a written scope with what was tested, what was repaired, and what would change the price.

Customer reviews
Reviews from homeowners we dispatched to for this problem.
"The technician started with the route, shutoff, and equipment location instead of jumping straight to a menu price. For dedicated circuits in Calabasas, that mattered because conduit route and heat pump load planning could have changed the scope. The best part was that the visit avoided a second trip because the access issue was handled early."
"For a Encino property around Amestoy Estates, the visit felt organized and specific. The repair option, replacement trigger, and repair method issue were all written down. We also appreciated that multi-zone AC was treated as a real field condition, not a generic warning, so the photos and closeout notes matched what we saw at the house."
"We sent photos before the appointment, and it helped. The furnace repair visit focused on venting route, the Lake Hollywood edge access route, and the local concern around airflow imbalance instead of guessing from the service label alone. That made the final recommendation useful because the estimate separated immediate stabilization from the follow-up scope."
"The estimate separated diagnosis from follow-up work, which mattered for our Larchmont Village home. A simple EV charger installation request turned into a better conversation about wire length, old wiring, and access near Melrose Avenue edge. There was no pressure, and the notes gave our property manager enough detail to approve the next step."
"The visit notes were specific enough for our property manager to understand the next decision. They named the water heater repair issue, the Mar Vista Hill access limits, the pan and drain route concern, and the reason heat pump conversion could affect timing. That level of detail helped because the technician explained what was safe to use and what needed to stay off."
"No coupon talk, just a clear route through the problem. The West Hills notes matched what the technician found on site, especially around Castle Peak, damage location, and compressor stress. We had enough information to compare options because the written scope made the repair-versus-replace decision much easier."
