Common air conditioner problems — diagnosis and GossTech fixes (detailed)

Below we list every common problem ACs develop, exactly how GossTech diagnoses each issue, and the typical repair steps. Use this as a troubleshooting reference and to understand why regular maintenance prevents many of these faults.

Note: Safety first — many AC repairs involve refrigerant handling and mains electrical work. GossTech technicians are trained and carry the right tools, PPE and certifications.

1. Air conditioner not powering on

Diagnosis steps

  • Check power supply (circuit breaker, isolator, fuses).
  • Test remote control batteries and infrared signal.
  • Inspect AC internal PCB and control board for visible damage.
  • Use multimeter to check incoming voltage to unit.

Typical repairs

  • Reset/replace tripped breakers or replace blown fuses.
  • Replace faulty isolator switches or tighten loose connections.
  • Replace remote or remote battery; re-program if needed.
  • Replace faulty PCB or control module if burnt or shorted.

2. Indoor unit blowing warm air

Diagnosis steps

  • Confirm thermostat settings and mode (cooling vs fan).
  • Check refrigerant pressure (low/high).
  • Inspect condenser (outdoor) for airflow restriction (blocked fins).
  • Check evaporator coil for frost/ice or heavy dirt.

Typical repairs

  • If refrigerant low: perform leak detection, repair leak and recharge to correct charge.
  • Clean condenser and clear obstructions around outdoor unit.
  • Defrost and clean evaporator; carry out full service.
  • Replace compressor if failed and unrecoverable (cost vs replacement considered).

3. Poor airflow from indoor unit

Diagnosis steps

  • Inspect and clean blower fan and motor.
  • Check for clogged air filters and blocked vents/ducts.
  • Test blower motor capacitor and motor windings.

Typical repairs

  • Clean or replace filters; advise frequency of filter cleaning.
  • Clean blower assembly; lubricate motor where applicable.
  • Replace faulty blower motor or capacitor.

4. Strange noises (clanking, grinding, hissing, buzzing)

Diagnosis steps

  • Localize noise source (indoor vs outdoor).
  • Inspect mounting brackets, fan blades, compressor mounting.
  • Check for refrigerant leak noises (hissing).
  • Check for seized fan motor bearings or loose panels.

Typical repairs

  • Tighten or replace mounts, anti-vibration pads.
  • Straighten or replace bent fan blades; balance fans.
  • Replace bearings or the entire fan motor if worn.
  • Repair refrigerant leak and confirm sound gone.

5. Water leakage from indoor unit

Diagnosis steps

  • Inspect drain pan and condensate drainage line for blockages.
  • Check refrigerant levels (overcooling can cause excess condensation).
  • Inspect unit tilt and mounting; check drain pipe installation.

Typical repairs

  • Clear clogged condensate drain with compressor or vacuum method.
  • Re-level indoor unit and secure drain line.
  • Replace damaged drain pan or condensate pump if used.

6. Unit frequently trips the breaker

Diagnosis steps

  • Measure current draw on compressor and fan.
  • Inspect electrical wiring for short circuits or loose connections.
  • Test start/run capacitors for failure.

Typical repairs

  • Replace faulty capacitors or start relays.
  • Tighten/replace wiring; replace breakers if faulty.
  • Replace compressor if drawing excessive current.

7. Bad odour from AC

Diagnosis steps

  • Inspect filters, evaporator coil and drain for mould/mildew.
  • Check for rodent or insect nests in ducting or outdoor unit.
  • Evaluate whether a burnt electronic smell is coming from PCB.

Typical repairs

  • Deep-clean coils, replace filters, sanitize drain and ductwork.
  • Remove nests, treat with antimicrobial solutions.
  • Replace damaged components causing burning smell.

8. Ice forming on evaporator coil

Diagnosis steps

  • Measure airflow (fan operation) and refrigerant pressure.
  • Inspect air filter and coil cleanliness.
  • Check thermostat and expansion valve operation.

Typical repairs

  • Restore airflow by cleaning filters/repairing blower.
  • Repair refrigerant charge issues (undercharge or restriction).
  • Replace faulty TXV or expansion device; thaw ice and fully dry unit before restart.

9. Refrigerant leaks

Diagnosis steps

  • Use electronic leak detector or UV dye to pinpoint leaks.
  • Pressure test the sealed system.
  • Inspect joints, pipe runs and valve cores.

Typical repairs

  • Repair or braze leaking joints; replace damaged pipe sections.
  • Evacuate, vacuum and recharge system to manufacturer specification.
  • Provide leak report and recommend long-term monitoring if recurring.

10. Compressor failure

Diagnosis steps

  • Measure resistance on compressor windings; check for electrical continuity.
  • Inspect for oil leaks, seizure or mechanical damage.
  • Check running current and protective devices.

Typical repairs

  • Where practical, replace compressor; match refrigerant and oil type.
  • If unit is old, advise replacement of entire system (cost analysis).
  • Repair start relay, capacitors or wiring if compressor otherwise healthy.

11. Thermostat or remote control faults

Diagnosis steps

  • Verify thermostat sensor readings and calibration.
  • Check remote receiver board and IR sensor.

Typical repairs

  • Recalibrate or replace thermostat head.
  • Replace remote or receiver module.

12. Frozen outdoor unit or fan not running

Diagnosis steps

  • Check for dirty coils, low refrigerant, or fan motor failure.
  • Verify outdoor unit has adequate ventilation.

Typical repairs

  • Thaw and clean outdoor coil, repair fan motor, replace if faulty.
  • Fix refrigerant issues and ensure clear airflow.
