5 Simple Air Con Maintenance Tips to Cut Your Power Bills

5 Simple Air Con Maintenance Tips to Cut Your Power Bills — air conditioning HVAC Blue Mountains Western Sydney NSW | Betar Air

Regular maintenance is the single best way to keep your air conditioner running efficiently and avoid expensive breakdowns. Here are five things you can do yourself:

1. Clean or Replace Filters Every 3 Months Dirty filters restrict airflow and force the system to work harder. Most split system filters simply slide out and can be washed with warm water.

2. Keep the Outdoor Unit Clear Make sure there's at least 50cm of clearance around the outdoor unit. Remove leaves, debris, and overgrown plants that can block airflow.

3. Check for Ice Build-Up If you see ice forming on the indoor unit, turn the system off and call a technician. This usually indicates a refrigerant issue or blocked airflow.

4. Don't Set It Too Cold Every degree lower costs more to run. Setting your AC to 24°C instead of 20°C can reduce running costs by up to 20%.

5. Book an Annual Service A professional service includes coil cleaning, refrigerant checks, electrical inspections, and efficiency testing — things you can't do yourself.

Betar Air offers annual service plans for homes and businesses across the Blue Mountains, Western Sydney, and the Central West.
