Book my free quoteThe Victorian Energy Upgrades program pays households to replace an old gas heater with an efficient reverse cycle system, which cools all summer and heats all winter from the one unit. We work out what your home qualifies for, handle every bit of the paperwork, and take the rebate straight off the price you pay. There is nothing for you to claim back later.
"We have had Efficient Air install 4 Hisense reverse cycle units over the last 12 months. Each time had been a trouble free experience. Jason and Kelly have been great to deal with. The installation crews have been on time and completed their work without fuss."
"The team at Efficient Air are so professional and thorough with their work. A massive thank you to Peter who came out to our place to advise us of the best possible options with various quotes and Tom who did a fantastic job installing our new multi split system."
"I have always had a great experience when needing services and products from Efficient Air. I have had split systems and radiators from them and the service has been very good. The split system keeps us cool in summer and warm in winter which is what we need right now in Melbourne!"

Four things worth checking now, while there is still time to do something about them. Two of these are a service, not a new system, and we will tell you which one you are looking at.
A few of the questions we hear most. Got another one? Just give us a call and we will talk it through.
We install and service all the leading brands: ActronAir, Braemar, Daikin, Fujitsu, Mitsubishi, Panasonic and Samsung. We recommend the right one for your home and budget rather than push one brand on everyone.
Yes. We are based in Emerald and cover Melbourne's south-east, the Knox area and the Dandenong Ranges. If you are not sure, give us a call and ask.
Yes. If you are replacing an old gas heater with an efficient reverse cycle system, you can get up to $3,500 back through the Victorian Energy Upgrades program. We check what your home qualifies for and handle the paperwork, so the rebate comes off your quote rather than something you claim back later. Eligibility criteria apply and we confirm your exact figure at the free on-site quote.
Often, yes. If the system is under about ten years old and only one or two rooms are a problem, a service or a zoning fix is usually the cheaper answer. We will say so rather than quote you a new system you do not need.
Give yourself a few weeks. From late spring the calendar fills quickly and the busiest stretch is the fortnight after the first serious hot spell, when everyone calls at once. Booking the quote early costs nothing and holds your place.
As a rule, a service every 2 to 3 years keeps a system running efficiently and catches small issues before they turn into expensive ones.
Yes. We quote the full job upfront and that is the price you pay, with no hourly surprises and no padded invoices.
We answer calls Monday to Friday, 9am to 5pm, and reply to online enquiries the same day during the week.
