Common Air Conditioner Problems & GossTech’s Diagnosis & Repair Approach
In our years of experience serving Nairobi, we have observed recurring air conditioner problems. Below is a detailed breakdown of common issues, how we diagnose them, and our typical repair or maintenance steps.
| Problem | Diagnosis Method | How GossTech Fixes It |
|---|---|---|
| 1. AC not cooling / weak cooling / insufficient cold air | — Check thermostat temperature & setting— Measure return-air and outlet-air temperature difference— Inspect air filter condition and airflow— Check refrigerant pressure levels with gauges | — Clean or replace clogged air filters— Clean evaporator and condenser coils to restore heat exchange— Check for and repair refrigerant leaks; recharge to correct level— Ensure outdoor unit has sufficient ventilation— Verify thermostat operation and recalibrate or replace if faulty |
| 2. AC blowing warm air | — Same steps as “no cooling”— Confirm compressor and condenser fan operation— Check refrigerant charge and pressures | — Repair or replace faulty compressor or fan — Fix refrigerant leaks and recharge — Clean condenser coil and ensure good airflow outside |
| 3. Water leaking / dripping inside or outside | — Inspect drain pipe and pan for blockages or damage— Check if drain pan is intact and properly aligned— Examine for frozen evaporator coil (which melts when turned off) | — Clear or unclog drain-line; flush drain pipe— Replace or reposition damaged drain pan— If evaporator coil freezes due to low refrigerant or airflow — restore refrigerant level and airflow; clean coils; check fan operation |
| 4. Poor or reduced airflow | — Check filter for dust/clogs— Inspect blower motor/fan for dust build-up or mechanical issues— Check air ducts (for ducted systems) or vents for blockage or closure | — Clean or replace filter— Remove dust/debris from blower wheel; lubricate or replace blower motor if needed— Clear ducts/vents or adjust them to open airflow pathways |
| 5. Unusual noises (rattling, buzzing, grinding, hissing) | — Listen to indoor and outdoor units during operation— Isolate source (blower, fan, compressor, refrigerant flow)— Use vibration analysis for mounting/fastening checks | — Tighten loose panels or screws— Replace or lubricate faulty fan or blower components— Fix refrigerant flow issues (e.g. replace or clean clogged capillary tubes or expansion valves)— For compressor problems — inspect mountings; replace compressor if internal damage is detected |
| 6. AC not turning on / power failure / frequent tripping | — Test power supply (voltage, stability)— Use multimeter to test capacitor, contactor, fuses, thermostat wiring— Inspect circuit breaker or wiring for faults | — Replace blown fuses or reset circuit breaker— Replace faulty capacitors or contactors— Repair or replace damaged wiring or thermostat wiring— Ensure proper earthing and stable power supply |
| 7. Refrigerant leak (visible oil stain, low pressure, freezing coils) | — Use electronic leak detector and UV dye if needed— Perform pressure test and gauge readings— Visual inspection around joints, valves, coil seams | — Repair or replace leaking pipes/valves/coils— Vacuum system and recharge with appropriate refrigerant type and correct amount— Perform leak-check again to ensure system stays sealed |
| 8. Frozen evaporator coil or ice build-up | — Visual inspection of indoor coil— Check airflow and refrigerant pressure | — Restore proper airflow (clean filter, blower); rectify refrigerant charge issues; clean coils; allow defrost then re-test |
| 9. Foul smells / musty odor from AC | — Inspect filter, drain pan, coils, and ductwork (for ducted systems) | — Clean or replace air filters; flush drain pan and clean drain-line; clean coils; disinfect ductwork if needed; suggest periodic cleaning to customer |
| 10. Thermostat malfunction (wrong temperature display, unresponsive controls) | — Use multimeter to verify voltage to thermostat— Test control signals and fan/ compressor response when adjusting thermostat | — Calibrate thermostat or replace if defective; verify correct wiring; ensure compatibility if thermostat was previously replaced |
| 11. Compressor failure / burnout | — Use multimeter to test winding resistances, insulation, and start/run capacitor; examine refrigerant pressures; check oil signs and overheating | — If compressor is damaged beyond repair — replace compressor (matching model and refrigerant) with proper installation; evacuate system and recharge refrigerant; test for proper cooling and pressures |
| 12. Electrical issues — short circuits, tripped breakers, sparking | — Visual inspection of wiring, terminals, connectors; use multimeter for insulation/resistance testing; check earthing and connections | — Replace burned wires or terminals; correct faulty earthing; install proper circuit breaker or surge protector; ensure safe and compliant electrical setup |
Example of Step-by-Step Diagnosis and Repair Workflow
- Initial inspection & history gathering: Our technician contacts you, arrives at your premises along Kangundo Road (or elsewhere in Nairobi), and asks for a description of the problem — e.g. “AC not cooling as before.”
- Visual & operational test: Turn on the AC, observe cooling performance, check air temperature differential, airflow strength, listen for strange noises, and inspect for leaks or ice formation.
- Filter, coil, and airflow check: Clean filter if dirty; if airflow remains weak, inspect blower or ductwork.
- Electrical and refrigerant system evaluation: Use multimeter to test power, capacitor, and wiring. Use pressure gauges and leak detector for refrigerant checks.
- Fix & replace parts as needed: Clean coils, clear drain lines; repair leaks; replace capacitors/blowers/compressors/thermostats, etc.
- System reassembly and testing: After repairs, run the AC through a full cycle, measure inlet/outlet temperatures, and verify stable operation over 15–30 minutes.
- Customer demonstration & care advice: Show customer that AC now cools properly, explain any replaced parts, and advise on preventive maintenance (e.g. clean filter monthly, avoid blocking outdoor unit, schedule annual servicing).
- Post-service documentation and warranty (if applicable): Provide invoice, parts replaced, and suggest next service date.
This systematic approach helps ensure that problems are fixed thoroughly — not just superficially — preventing repeat breakdowns and prolonging AC life.

Maintenance Tips — For Better AC Life & Performance
To maximize your air conditioner’s lifespan and efficiency, we recommend:
- Clean or replace air filters every 1–2 months — especially during Kenya’s dusty season.
- Ensure outdoor/condenser unit is not blocked — keep at least 30 cm clearance from walls, plants, or debris for good airflow.
- Schedule a full servicing at least once every 12 months — coil cleaning, refrigerant pressure check, electrical inspection.
- Avoid frequent on/off cycles — use the AC for several hours rather than switching it on and off repeatedly.
- Use a proper thermostat setting (e.g. 24–26 °C) — avoid extreme cooling which stresses the compressor.
- Use a surge protector or stabilizer — Kenya’s power fluctuations can damage AC components.
- Promptly address unusual noises, leaks, or odors — early diagnosis prevents bigger failures.
- Keep the drain line clear — especially in rainy season, or indoors where humidity is high.
