AIRCON HIGH ELECTRICITY BILL \u2014 CAUSES & FIX
Spike in your aircon electricity bill? Uncle 7 Aircon explains the dirty filters, low gas, wrong settings and old units that waste power in Singapore homes.
A sudden jump in your electricity bill is often your aircon working harder than it should. In Singapore's 24/7 humidity, even small inefficiencies multiply quickly.
Common Causes
- Dirty filters restricting airflow
- Low refrigerant forcing longer run times
- Thermostat set too low (below 22°C)
- Oversized or undersized unit
- Old compressor losing efficiency
- Leaky ducts or poor insulation
Quick Fixes
- Clean or replace filters every 2-4 weeks
- Set temperature to 24-25°C with fan mode
- Close windows and draw curtains during the day
- Schedule annual chemical servicing
When To Call Uncle 7
