Not cooling

Fault guide
What is your air conditioner telling you?
Six common problems, what usually causes them and what you can safely check before you call. For anything electrical, switch off and let us look.
Leaking water
Drips from the indoor unit
Usual causes
- Blocked drain line
- Unit not level
- Iced coil from low gas
What to do
Switch it off and put a towel down. A blocked drain is usually fixed during a service.
Noisy
Rattles, hums or clicks
Usual causes
- Loose panel or bracket
- Worn fan motor bearing
- Compressor starting hard
What to do
A rattle is often a loose screw. A loud hum that stops and starts needs a technician.
Bad smell
Musty or burning smell
Usual causes
- Mould on the coil
- Dust burning off after a long break
- Electrical fault
What to do
A musty smell needs a clean. A burning smell means switch off at the wall and call us.
Tripping
Switches off the breaker
Usual causes
- Voltage drops in your area
- Faulty capacitor
- Short in the wiring
What to do
Do not keep resetting it. A stabiliser and a check of the capacitor usually solve it.
Remote not working
No response from the unit
Usual causes
- Weak batteries
- Blocked sensor
- Board fault
What to do
Try new batteries and clean the sensor window. If the light does not come on, book a check.
Stay safe
Three things never to do yourself
- 01Open the outdoor unit or touch the capacitor. It can hold a charge even when unplugged.
- 02Top up gas from a roadside cylinder. Wrong gas or pressure can ruin the compressor.
- 03Keep resetting a breaker that trips. Switch off and call a technician.
Everyday tips
Lower bills, longer life
24°
Set it to 24 to 25°C. Every degree lower adds about 6 percent to your power use.
2 wks
Rinse the filters every two weeks in the dry season, when harmattan dust is heavy.
Doors
Keep doors and windows closed while it runs, and curtains drawn in the afternoon.
Volts
Use a stabiliser where voltage swings. It protects the compressor and the board.
Still not right?
Book a callout. It is free if you go ahead with the repair.
