FAQs

Q.
Why Is The The Air-con Leaking Water?
A.
Normal air-conditioning system will have water condensate in the indoor unit (Fan-Coil) & flow out through a drainage pipe. If the drainage pipe is chocked, water will start to leak. When the unit freezes up, water will start to leak too. Call a qualified technician to rectify the problem.
Q.
Why Is My Air-con Not Cold?
A.
  • The blower and air filter is dirty and clogged with dust
  • The thermostat is set too high
  • The unit is undersize
  • The orientation of the room (e.g. facing direct sunlight)
  • The refrigerant gas needs to be topped up
Q.
Why Does The Indoor Unit Freeze Up?
A.
Due to lack of refrigerant. Faulty capacitor or fan motor. It may simply need to carry out chemical overhauling, due to indoor coil choked.
Q.
Why Is The Air-con Noisy?
A.
  • The spare part might be faulty and needs to be changed
  • The blower and fan-coil may be dirty
  • Vibration noise due to uneven wall surface
Q.
Why Is My Air-con Unit Producing A Foul Smell?
A.
This could be due to the smell of cigarettes, odours or other air pollutants being absorbed into the unit and thus being discharged with the air flow.
Q.
Why Does The Air-con Need Chemical Overhauling?
A.
When the air-conditioner, condenser & evaporator get badly chocked, (internal & external) normal servicing can't improve the condition. Chemical overhaul need to be applied. The unit needs to be dismantled & strip part by part. Apply the coil with chemical & wash out with water.
