Air Conditioning Carlton A Simple Plan for Every Season
Carlton sits between Kogarah and Allawah, with Carlton station at its centre and a mix of older houses and unit blocks around it. Most air conditioning problems we see here come down to the same thing: the system was forgotten until it stopped working.

Air conditioning in Carlton lasts longer and costs less to run with a little attention through the year. Filters need regular rinsing, the outdoor unit needs clear space, and a professional service once a year catches small faults early. Follow the simple seasonal plan below and book us for the parts that need a technician. Alpha & Omega has looked after systems in Sydney's south since 1989.
A Season-by-Season Air Conditioning Plan for Carlton Homes
Four checkpoints, about ten minutes each, plus one professional service.
Spring (September to November)
Book your annual service, rinse filters and clear around the outdoor unit before summer.
Summer (December to February)
Rinse filters every two to four weeks and watch for leaks or weak cooling.
Autumn (March to May)
Give filters a clean after the heavy season and check the drain is flowing.
Winter (June to August)
Switch to heating, check it warms evenly and clean filters before heavy use.

Carlton Air Conditioning Care Questions
How often should I clean my air conditioner filters?
Every two to four weeks during heavy use in summer and winter, and every couple of months otherwise.
When is the best time to service an air conditioner?
Spring, before summer demand peaks. A second check before winter is useful if you rely on it for heating.
Can I clean the coil myself?
We recommend leaving coil and fan cleaning to a technician, as they need proper tools and chemicals and sit near electrical parts.
What happens if I never service my system?
Dust builds up, efficiency drops, running costs rise and small faults turn into bigger repairs.
Do you service all brands?
We service most common brands, and we specialise in supplying and installing Daikin.
Is your servicing work licensed?
Yes, under our ARC licence AU54289 and NSW contractor licence 329810C.
