Why AC Cleaning Matters Before a Melbourne Winter
Melbourne’s climate is a tricky mix — damp mornings, sudden temperature drops, and plenty of indoor heating use. If your split system hasn’t been cleaned since summer, dust, pollen, and mould can clog filters and coils, making your heater less efficient.
According to Energy.gov.au, regular maintenance can cut energy use by up to 15%. That’s a handy saving during a cold Victorian winter when electricity costs already run high.
