Why you should service your air conditioner every 6 months: the science of efficiency
Not an upsell, just physics. The data behind a biannual maintenance schedule.
At Amali Electric, we recommend servicing your split system or ducted air conditioner every 6 months. It's not an upsell, it's physics. Here's why the data backs a biannual maintenance schedule.
Five evidence-based reasons
- 01Dirty filters increase energy consumption by 5 to 15%. When filters are clogged, your system works harder to push air through. Manufacturers recommend cleaning or replacing filters every 1 to 3 months depending on usage.
- 02Refrigerant levels degrade over time. Even a 10% refrigerant loss can reduce system efficiency by up to 20% and cause the compressor to overheat, leading to premature failure.
- 03Coil cleaning prevents mould and bacteria. The indoor evaporator coil collects condensation and can harbour mould if not cleaned. This affects indoor air quality and can trigger respiratory issues.
- 04Drain line blockages cause water damage. A blocked condensate drain can overflow, damaging walls, ceilings and flooring. Servicing includes clearing and testing the drain line.
- 05Pre-summer and post-summer servicing aligns with Australian climate demands. Prepare for peak load before summer, clean off accumulated dust and mould after heavy use.
Ducted-specific concerns
Homes with ducted systems older than 10 years should have duct integrity checked during servicing. Research shows duct leakage can waste 20 to 30% of conditioned air into the roof cavity, directly increasing running costs.
Smart thermostat optimisation
During a service, your technician can calibrate thermostat settings for seasonal efficiency. NSW Government energy advice recommends air conditioner set points of 23 to 26°C for cooling.
