Roof heat
Without good ceiling insulation, roof heat radiates into rooms all afternoon.

Air Conditioning Chifley Fix the Leaks Before You Cool
Chifley is a small, quiet suburb of post-war houses between Malabar and Little Bay. Many were built before ceiling insulation was standard, so heat pours in through the roof in summer and escapes just as fast in winter.

- Insulate, then air condition
Air conditioning in Chifley homes works best once the house holds onto the cool. In older houses with little ceiling insulation, a lot of the heat your system fights comes straight through the roof. Topping up insulation, shading west windows and sealing draughts can mean a smaller system does the job and costs less to run. Alpha & Omega gives practical advice and has worked across Sydney since 1989.
Before you buy
Why Chifley Homes Benefit From Insulation First
The cheapest air conditioning is the cooling you never need.
Draughts
Gaps around old windows and doors let cooled or heated air escape.
Afternoon sun
Unshaded west windows add heat right when you want to relax.
Simple improvements to discuss
- Topping up ceiling insulation (by a specialist)
- External blinds or awnings on west windows
- Draught seals on doors and windows
- Then a correctly sized inverter system

Chifley FAQs
Chifley Efficiency and Air Conditioning Questions
Should I insulate before installing air conditioning?
If your ceiling insulation is thin or missing, it is usually worth doing first. It reduces the size of system you need and lowers running costs.
Do you install insulation?
No, insulation is installed by specialist contractors. We can tell you if it looks like a worthwhile improvement.
Will a smaller air conditioner do the job after insulating?
Often, yes. Less heat coming in means less capacity needed.
What else reduces running costs?
Shading west windows, sealing draughts and setting cooling to around 24 to 26°C all help.
Is inverter technology worth it?
Yes. Inverter systems adjust their output and use less power than older fixed-speed units.
Who licenses your Chifley installers?
Yes, all Chifley work is done under ARC licence AU54289 and NSW contractor licence 329810C.
