Common Air Conditioner Problems & How GossTech Diagnoses and Repairs Them
Below is a detailed breakdown of the most frequent air conditioner issues — and how GossTech handles each one:
| Problem | How GossTech Diagnoses It | Repair & Maintenance Process |
|---|---|---|
| 1. AC Not Cooling (insufficient cooling or warm air only) | Check thermostat settings; measure supply and return air temperature; inspect evaporator and condenser coils; check refrigerant pressure and levels; test compressor and fan operation; ensure airflow isn’t blocked | Clean or replace dirty filters; clean coils; remove blockages; if refrigerant is low — locate and repair leak, then recharge refrigerant; repair or replace malfunctioning compressor or fan. |
| 2. Refrigerant Leak | Perform pressure test; use leak-detection (electronic or soap bubble) around joints, valves, piping and coils; visually inspect for oil stains | Seal or replace leaking joints/pipes; replace faulty valves or coils; evacuate system; recharge with correct refrigerant gas; test for leaks again to ensure sealing. |
| 3. Water Leaking / Dripping Indoors | Check drain pan and drain line for blockages/clogs; check insulation and sealing around piping; inspect condensate pump (if present) | Clear and flush drain line; clean or replace clogged drain pan; ensure proper slope of drain piping; fix or replace condensate pump; reseal insulation and joints to prevent condensation. |
| 4. Unusual Noise (buzzing, clanking, rattling, hissing) | Run AC and listen to noise source (indoor/outdoor unit); inspect fan blades, motor bearings, mounts, vibration dampers; check compressor and refrigerant flow | Tighten or replace loose screws, mounts, or dampers; replace worn fan motors or bearings; replace compressor if faulty; ensure refrigerant flow is smooth; tighten all electrical and mechanical connections. |
| 5. Foul Odor or Musty Smell from AC | Smell test; inspect air filters, evaporator coils, drip pans, ductwork (if applicable) for mold/mildew or stale water; inspect drainage | Deep-clean or replace air filters; clean evaporator coils and drip pans; flush drain lines; disinfect drain pan or ductwork; if needed — treat with anti-fungal spray. |
| 6. Frozen Evaporator Coil / Ice Formation | Inspect airflow (dirty filter or blocked vents), refrigerant pressure, coil temperature; measure supply/return temps; visually inspect ice formation | Clean or replace filters; clear airflow obstructions; check fan operation; correct refrigerant pressure; defrost coil; once defrosted, clean and restart; if refrigerant pressure abnormal — repair leak & recharge. |
| 7. AC Won’t Turn On / No Power / Electrical Faults | Check power supply, wiring, circuit breaker; test internal wiring, control board, thermostat; inspect capacitors and contactors | Repair or replace faulty wiring; reset or replace breaker; repair/replace damaged control board, thermostat, capacitors, or contactors; ensure proper earthing & safety compliance. |
| 8. High Electricity Consumption / AC Overheating | Inspect filter/coil cleanliness, airflow, refrigerant charge, compressor strain; measure current draw; check for overworked compressor | Clean filters/coils; relieve compressor strain (repair or replace faulty components); ensure refrigerant at optimal level; recommend best usage practices; advise on insulation improvements if necessary. |
| 9. Short Cycling (AC constantly turns on/off) | Monitor thermostat, compressor cycles, refrigerant pressure, airflow, capacitor health | Replace faulty thermostat, capacitors or contactors; repair refrigerant issues; clean coils / filters to ensure proper airflow; check and test after repair to confirm stable cycling. |
| 10. Outdoor Unit Fan / Condenser Fan Failure | Observe operation of outdoor fan during runtime; test motor current draw; visually inspect blades and mounts | Replace faulty fan motor; repair or replace damaged fan blades; lubricate bearings; secure mounts and dampers; test for proper airflow and cooling after repair. |
| 11. Compressor Failure / Locked Compressor | Test compressor start relay, capacitors; check voltage supply; measure amperage; listen for humming or locked rotor | Replace faulty start relay or capacitors; if compressor is damaged, replace compressor unit; ensure correct refrigerant type and pressure; test system performance thoroughly. |
| 12. Thermostat or Control Board Malfunction | Test thermostat accuracy, control signals, wiring, and voltage; check for error codes (if digital unit) | Repair or replace thermostat; repair or replace control board; test controls, sensors, and safety switches; recalibrate thermostat settings if necessary. |
For each of the problems above, GossTech technicians begin with a comprehensive diagnostic assessment — combining visual inspection, airflow & temperature measurements, pressure testing, electrical testing, or leak detection — before recommending the most appropriate repair or maintenance action. This ensures that the root cause is addressed rather than just symptoms.
