How we repair your Mini-Split/Ductless AC
A ductless mini-split air conditioner pairs an outdoor inverter compressor with one or more wall, ceiling or floor heads that cool individual rooms without ductwork. A mini-split/ductless AC typically includes a compressor, condenser and evaporator coils, fans, a capacitor and contactor, and a thermostat, or a water pump and pads on evaporative coolers. A technician checks airflow, electrical parts and refrigerant pressures, and inspects drains and coils.

Common Mini-Split/Ductless AC problems we fix
What usually causes each symptom, and what our technician checks to confirm it.
Musty smell when running
- Likely causes
- Mold or biofilm growing on the blower wheel and coil inside the head, often from dirty filters and long runs with high humidity.
- What our technician checks
- The head covers are removed and the barrel-style blower wheel and coil are inspected for growth that requires a deep cleaning.
Indoor head blinking an error code
- Likely causes
- A communication fault between the indoor and outdoor boards, a failed temperature sensor, or a fault reported by the inverter board.
- What our technician checks
- The technician reads the fault code history, checks the interconnect wiring for voltage and continuity, and tests thermistors against their resistance charts.
Room not cooling but head is blowing
- Likely causes
- A refrigerant leak at the flare connections, a failed outdoor fan motor, or an inverter compressor that is not ramping up.
- What our technician checks
- Flare fittings are leak-tested, outdoor fan and compressor operation are verified, and pressures are read at the service port.
Louvers stuck or not swinging
- Likely causes
- A failed louver stepper motor, a broken louver linkage, or a fault on the indoor control board.
- What our technician checks
- The stepper motor is tested for continuity and drive signal, and the louver arms are inspected for cracks.
Water dripping from the indoor head
- Likely causes
- A clogged condensate drain, a head that is not level, or a dirty coil and blower wheel overflowing the drain tray.
- What our technician checks
- The drain line is flushed, the mounting plate is checked with a level, and the coil and tray are inspected for slime and debris.
Remote not controlling the unit
- Likely causes
- Dead remote batteries, a failed infrared receiver on the head, or a display board fault.
- What our technician checks
- The remote signal is tested, the unit is run from the manual button on the head, and the receiver and display board are checked.
Quick checks you can do safely
- Replace the remote batteries and confirm it is set to cool mode.
- Remove and rinse the washable filters behind the front panel.
- Check that the outdoor unit is powered and not buried in snow or debris.
- Note any blinking light pattern or code on the indoor head.
- Turn the unit off at the breaker for a few minutes to reset the boards.
Safety first: Inverter boards hold high voltage after shutoff and refrigerant connections must only be opened by an EPA-certified technician.
