Every common AC problem — one by one (symptoms, GossTech diagnosis, repair approach)
The table below lists principal faults you may encounter. For each we explain how GossTech diagnoses the cause and the standard repair approach.
| Fault / Symptom | Diagnostic steps (what GossTech checks) | Typical GossTech repair actions & notes |
|---|---|---|
| Not cooling (unit runs but no cold air) | Check thermostat settings, measure suction/discharge pressures, inspect compressor behaviour, check refrigerant levels, inspect airflow (filters, blower), measure evaporator coil temp. | If low refrigerant — perform leak test, repair leak, evacuate & recharge with correct refrigerant. If compressor mechanical failure — replace compressor or advise replacement. Clean/replace filters and clear airflow obstructions. |
| Weak airflow from indoor unit | Inspect/clean filters, measure motor amp draw, check fan/blower wheel integrity, inspect ducting (for ducted systems) and fan motor capacitor. | Clean/replace filters, repair or replace blower motor or capacitor, clear/repair duct obstructions, rebalance airflow. |
| Water leaking inside (drips from indoor unit) | Inspect drain pan, check drain hose for blockages, check slope of drain line and condensate pump (if any), check frost on coil (indicates airflow/refrigerant issues). | Clear drain pipe, replace damaged drain pan or pump, re-slope drain, fix airflow or refrigerant issues causing coil freeze. |
| Noise — rattling, grinding, or loud operation | Determine noise source: mounting, fan, compressor, refrigerant flow, or bearing failure. Observe during operation and isolate components. | Tighten mounts; replace worn fan blades or bearings; replace faulty compressor mounts; replace failing motors; vibration isolation pads installed if needed. |
| Unit not starting / no power | Test electrical supply, check isolator switch, inspect remote/thermostat, check fuses, breakers and contactors, measure PCB power rails. | Reset/replace blown fuses/breaker; repair/replace contactor or PCB; fix wiring faults and faulty remotes or thermostats. |
| Frequent tripping of MCB / breaker | Measure current draw of compressor & fan; check for short circuits, capacitor health, motor overloads. | Replace faulty capacitor, fix short circuits, replace damaged wiring, install appropriate MCB rating if required and safe. |
| Compressor not running (compressor locked) | Check capacitor, contactor operation, measure start/run currents, inspect for seized compressor. | Replace start/run capacitor or contactor if faulty. If compressor seized or burnt, replace compressor or advise system replacement if old. |
| Frosting or frozen evaporator coil | Check airflow restrictions, refrigerant charge, expansion valve operation and ambient conditions. | Restore airflow (clean filters), repair refrigerant charge or TXV/expansion valve, defrost and recommission system. |
| Refrigerant leak (oil stains, low charge) | Perform electronic leak detection, soap test on joints, UV dye test if required, inspect common leak points (flare joints, brazed fittings, valve cores). | Repair/replace leaking joints, replace faulty valves or driers, evacuate system, perform vacuum, and recharge with specified refrigerant. |
| Bad or musty odour from unit | Inspect filters, drain pan, coil for mold/mildew, check ductwork for contamination, test for dead pests. | Deep-clean coils and drain pan, replace filters, apply antibacterial treatment, clean ducts (if required), install UV or ionizer add-on upon request. |
| Remote control / sensor issues | Test remote battery, check IR receptor, verify thermostat sensor calibration and connection to PCB. | Replace remote or receiver, recalibrate/replace sensors, reset control board. |
| PCB / control board faults | Visual inspection for burnt components, measure supply rails and communications, check for water ingress. | Replace faulty PCB or individual components; protect with conformal coating if moisture was cause. |
| Uneven cooling in multi-split or ducted systems | Measure airflows across zones, inspect dampers, check refrigerant distribution and compressor capacity. | Re-balance ducts, repair or replace dampers, check refrigerant circuits for blockages, advise system upgrade if undersized. |
| High energy bills / poor efficiency | Check refrigerant charge, coil cleanliness, compressor performance, thermostat calibration and seal of space. | Clean coils, fix refrigerant charge, replace worn components, recommend insulation improvements or upgrade to high-efficiency inverter units. |
| Short cycling (turns on/off frequently) | Check thermostat placement, refrigerant charge, compressor health, oversized unit, or electrical issues. | Correct thermostat placement, fix refrigerant or electrical faults, repair or replace defective valves/sensors, advise on correct system sizing if oversized. |
How GossTech diagnoses — step-by-step approach
- Remote pre-check (phone/WhatsApp): initial questions to understand symptoms, model & location; request photos if possible.
- On-site arrival & inspection: visual inspection of indoor & outdoor units, electrical isolation, sound & vibration checks, filter & coil inspection.
- Instrumented tests: voltmeter/ammeter, refrigerant pressure gauges, leak detector, vacuum pump if needed, temperature probes and thermostat checks.
- Report & recommendation: clear written estimate with parts needed, options (repair vs replace), and recommended preventive steps.
- Repair & verification: technicians perform agreed repairs, test run, and hand over a service report with system readings and tips.
Preventive maintenance checklist (recommended actions)
| Item | Action |
|---|---|
| Filters | Clean or replace every 1–3 months depending on use and environment. |
| Coils (evaporator & condenser) | Clean annually or more often in dusty environments. |
| Drain lines & pan | Clear & disinfect drains during service visits. |
| Electrical connections | Tighten & inspect for corrosion; check contactors and capacitors. |
| Refrigerant levels | Check for correct charge and leaks annually. |
| Fan motors & belts | Inspect and lubricate where applicable. |
| Thermostat calibration | Verify and recalibrate; replace batteries if applicable. |
| Overall system test | Run performance checks and record temperatures/pressures. |
GossTech offers tailored maintenance plans (quarterly, bi-annual, annual) with service logs to preserve warranty and system longevity.
