How to Diagnose Your Aircond Problem
Most aircond problems fall into a few predictable categories. Use this guide to identify what is wrong before calling a technician.
Problem: Aircond Not Cold
- Check if set temperature is lower than room temperature
- Is the air filter blocked? Remove, rinse, refit
- Is the outdoor fan running?
- Is there ice on the indoor coil?
Professional fix: Low gas (RM 120+), dirty coil (RM 120+), faulty capacitor (RM 180)
Problem: Aircond Leaking Water
- Check if the indoor unit is mounted level
- Look at the drain pipe outlet — is it blocked?
Professional fix: Drain pipe clearing (RM 120), chemical wash (RM 120)
Problem: Aircond Making Noise
- Rattling from indoor: loose front panel or debris in blower wheel
- Grinding/metal-on-metal: fan motor bearing failing
- Hissing: possible refrigerant leak — switch off immediately
