AIRCON NOT COLD - CAUSES & FIX
Aircon not cold? Uncle 7 Aircon explains the top causes - dirty filters, low gas, faulty compressor - and how to fix them in Singapore homes.
An aircon that runs but isn't cold usually points to one of a few culprits: dirty filters and coils, low refrigerant, a failing capacitor, or a tired compressor. Here's how to tell the difference and what to do.
Top Causes
- Dirty filters and fan coil restricting airflow
- Low refrigerant from a slow leak
- Faulty capacitor stopping the compressor
- Failing compressor (older units)
- Blocked outdoor condenser
Quick Checks Before You Call
- Set mode to Cool (not Fan or Dry)
- Set temperature below room temperature
- Vacuum the filters and switch on again
- Check the outdoor unit is running
