What the symptom usually means
Most AC failures trace back to airflow, drainage, refrigerant or an electrical part. The table lists what a technician checks first for each symptom.
| Symptom | Usual causes | Safe to check yourself |
|---|---|---|
| Will not turn on | Tripped breaker, failed capacitor, control board or thermostat fault | Breaker, thermostat batteries and mode |
| Runs but blows warm air | Low refrigerant from a leak, dirty outdoor coil, failed compressor or fan motor | Filter, and that the outdoor unit is clear of debris |
| Weak airflow | Clogged filter, dirty indoor coil or blower wheel, failing blower motor | Filter |
| Water leaking indoors | Blocked condensate drain, dirty coil, failed drain pump | Turn the system off to stop the leak |
| Ice on the coil or lines | Restricted airflow or low refrigerant | Turn the system off and let it thaw |
| Short cycling or uneven rooms | Sensor or thermostat fault, wrong settings, sizing | Thermostat or remote settings |
| Blinking light or error code on a mini split | The code names the fault | Mitsubishi error code guide |
Leave refrigerant and electrical parts to a technician. Federal rules require EPA Section 608 certification to handle refrigerant, and capacitors hold a charge after the power is off.

Mini split repair and central AC repair
The two systems fail in different ways, so it helps to say which one you have when you call.
| Mini split | Central air | |
|---|---|---|
| Common faults | Dirty coil and blower wheel, drain problems, sensors, inverter board, communication errors | Capacitor, contactor, fan motor, refrigerant leaks, duct and drain problems |
| How it reports a fault | Blinking lights or a code on the controller | Usually no code. The thermostat calls and nothing happens |
| Where to read more | Mini split repair in Los Angeles | AC replacement, if the system is past repair |
Many mini split cooling and leaking complaints come from a unit that has never been cleaned. A mini split cleaning is $199 for the first indoor unit and $59.99 for each additional one.
Repair conditions specific to Los Angeles
Where the equipment sits and where you live change what fails and how long a repair takes.
- Roof-mounted equipment. Many Los Angeles homes and apartment buildings have the condenser or a package unit on the roof. Tell us when you book so the technician brings the right ladder.
- Salt air. In the South Bay and beach cities, salt air corrodes outdoor coils and electrical connections faster than it does inland.
- Older refrigerant. R-22 has not been made or imported in the United States since January 1, 2020. Existing R-22 systems can still be serviced with reclaimed refrigerant, at a higher price.
- Rentals. For a tenant-occupied unit we arrange access with the tenant and send the invoice by email. See mini split service for rental properties.

Which brands do you repair?

Should I repair or replace my air conditioner?
Multiply the repair quote by the age of the system. If the result is over $5,000 on a system more than 10 years old, get a replacement quote. Replacement quotes from Dr. Ductless are free.
Why is my AC running but not cooling?
The usual causes are a clogged filter, a dirty outdoor coil, low refrigerant from a leak, or a failed compressor or fan motor. Check the filter and clear debris from the outdoor unit, then book a diagnostic visit if it still does not cool.
