Our Air Conditioner Services
GossTech offers a complete range of services to keep your AC units running smoothly, efficiently, and reliably throughout the year — from installation to emergency repairs.
🔧 Installation
- Supply and professional installation of new split‑unit and window air conditioners.
- Proper mounting of both indoor and outdoor units, ensure correct positioning, secure wall brackets, vibration dampeners, and safe routing of refrigerant piping and electrical wiring.
- Vacuuming the refrigerant lines, pressure‑testing, and charging the system to factory-specified refrigerant levels.
- Final functional test: cooling performance, airflow, drainage, noise level, power draw, thermostat calibration.
🧼 Servicing & Preventive Maintenance
Regular servicing is key to maximizing AC efficiency, prolonging lifespan, and preventing breakdowns. Our standard servicing package includes:
- Cleaning or replacing air filters.
- Cleaning evaporator and condenser coils.
- Checking and clearing drain pipes and drain pans to avoid water leakage.
- Checking refrigerant pressure and topping up if needed.
- Verifying electrical connections, fuses/circuit breakers, and checking for wear or corrosion.
- Testing thermostat accuracy and airflow.
- Lubricating moving parts (fan motors, etc.) where applicable.
We recommend servicing at least twice a year (before the beginning of hot seasons).
🔧 Repair & Maintenance
When an AC unit fails or underperforms, we step in to diagnose and fix the issue — whether mechanical, electrical, or refrigerant‑related. We handle urgent repairs and also offer maintenance contracts for businesses and apartments.
Common Air Conditioner Problems — Diagnosis & Repair
The table below outlines the most frequent AC problems we encounter, how GossTech diagnoses them, and the typical repair solutions we implement.
| Problem | Diagnosis (What GossTech Does) | Repair / Solution |
|---|---|---|
| Not Cooling / Insufficient Cooling | – Check thermostat setting and room vs ambient temperatures – Measure refrigerant pressure – Inspect air filters, evaporator coils, condenser coils for dirt/obstruction – Check compressor operation, fan speeds, airflow – Verify indoor/outdoor units operations | – Clean or replace filters; clean coils – Repair or replace dirty/blocked condenser – Recharge refrigerant if under‑charged (after fixing leak) – Replace faulty compressor or fan motor if not running properly – Adjust thermostat or recalibrate sensors |
| Water Leakage (indoor drip or puddle under indoor unit) | – Check drain pipe and pan for clogs or blockages – Inspect condensation build-up – Examine mounting angle of indoor unit (improper tilt) – Check refrigerant levels (icing causing melt-off) | – Clear blockages in drain pipe/pan – Clear condensate line and install cleaning trap – Re‑mount unit level if misaligned – If icing from low refrigerant, repair leak and recharge refrigerant – Replace defective drainage tray if cracked |
| Loud Noise (buzzing, rattling, humming, banging) | – Listen to indoor and outdoor units during operation – Check for loose mounting, loose screws, vibration isolation – Inspect fan blades (indoor blower, outdoor condenser fan) for obstructions or damage – Examine compressor mount and housing | – Tighten mounting bolts and screws – Add or replace vibration dampeners – Repair or replace damaged fan blades or motors – Replace noisy compressor (if bearing failure) – Insulate or reposition outdoor unit away from walls/fences |
| Frequent On/Off Cycling (short‑cycling) | – Check thermostat or sensor for faults – Measure compressor and fan current draw – Inspect refrigerant pressure (overcharge or undercharge) – Verify airflow (clean filters, unobstructed vents) | – Repair or replace faulty thermostat or sensor – Correct refrigerant charge – Clean or replace filters; remove vent obstructions – Repair defective fan motor or blower wheel |
| No Power / AC Does Not Turn On | – Inspect electrical connection (socket, wiring, switch) – Check circuit breaker or fuse – Test remote control or wall control unit – Inspect indoor control board / capacitor / main board for damage | – Repair or replace faulty wiring or socket – Replace blown fuse or reset/rewire breaker – Replace faulty remote, wall unit, or control board – Replace burnt capacitors or damaged control module |
| Refrigerant Leak (icing inside, hissing sound, oil stains) | – Visual inspection of refrigerant lines, joints, valves for signs of oil or refrigerant stains – Pressure‑test with nitrogen – Use leak‑detector or soap‑water method to locate leak spot | – Repair or replace leaking copper lines, joints, valves – Evacuate lines, vacuum, and recharge to correct refrigerant level – Pressure‑test again to confirm leak fixed before final test run |
| Poor Airflow / Weak Air Movement | – Check and clean air filters, vents, ductwork – Test blower fan speed – Inspect for blocked or collapsed ducts (window‑unit or central ducted AC) – Examine air return and supply vents for obstruction | – Clean filters and vents – Repair or replace blower fan or motor – Repair or straighten ducts; replace damaged duct sections – Remove obstructions at supply/return vents; re-balance airflow distribution |
| Thermostat or Sensor Malfunction (wrong temperature reading, AC doesn’t respond) | – Compare room temperature vs thermostat reading – Test sensor resistance and wiring – Check thermostat settings and battery (if remote sensor) | – Recalibrate thermostat or replace sensor – Replace faulty control unit or remote – Re-wire sensor properly if wiring damaged |
| Condensation Freeze / Frost on Evaporator Coil | – Measure refrigerant pressure (low refrigerant) – Check airflow (air filter / blower under‑performing) – Confirm thermostat set improperly or temperature sensor issue | – Repair refrigerant leak and recharge – Clean/replace filters and improve airflow (fan repair) – Adjust thermostat settings or replace faulty sensor |
| Electrical Surges / Frequent Tripping | – Inspect wiring and power supply stability – Check capacitor, compressor current draw, starting relay, overload protector – Test for short‑circuits or ground faults | – Replace capacitors, relays, overload protectors – Re-wire faulty electrical connections – Suggest installation of surge protector or dedicated circuit if supply issues in building |

Frequently Asked Questions (FAQ)
Q: How often should I service my air conditioner?
A: We recommend servicing at least twice a year — ideally before the start of the hot seasons — to maintain efficiency, prevent breakdowns, and increase lifespan.
Q: My AC is still cooling, but the fan seems weak — is that a serious issue?
A: Yes. Weak airflow often indicates filter blockage or blower/fan motor issues. If left unattended, it can cause freezing, compressor overload, or inefficient cooling — we strongly advise a check‑up.
Q: Can GossTech install a new AC unit I’ve already purchased?
A: Absolutely. Whether you bought the AC locally or abroad, we can handle expert installation and safe commissioning with vacuuming, refrigerant charging, and pressure testing.
