Our Services
Hot Water Systems
If your hot water system is not working, give us a call and we will come and fix it fast. If it is beyond repair, we can install a new system.We work with gas, electric, continuous flow gas and heat pump hot water systems.
The major brands we repair and install include Vulcan, Dux, Rinnai and AquaMax.
Why Melbourne Homeowners Are Switching to Heat Pump Hot Water
Heat pump hot water systems are an energy efficient alternative to conventional electric hot water systems. They can use less electricity, reduce running costs and work well with solar power.
Eligible Victorian households may be able to access government rebates and discounts when installing an eligible heat pump system.
In addition, new Victorian energy efficiency standards that apply from 1 March 2027 for rental properties will require an efficient electric hot water system when an existing system reaches the end of its life.
MJ Air installs heat pump hot water systems including Midea, Emerald, Ecogenica, PowerBay, iStore and Sanden. Rinnai also offers a range of heat pump hot water systems in Australia.. We can help you choose a system to suit your home, hot water needs and available space.

Get the Air Conditioner in Your Melbourne Home Ready for Summer
With summer approaching, the last thing you want is for your air conditioner to stop working when Melbourne has a run of hot weather. Melbourne’s weather can change quickly, so it makes sense to have your system checked before you need it most.
At MJ Air, we specialise in servicing all types of air conditioners, including split systems and evaporative cooling systems.
We service many of the leading air conditioning brands, including Brivis, Bonaire, Braemar, Breezair, Carrier, Celair, Coolair, Daikin, Fujitsu, Mitsubishi, Rinnai and Samsung. Whatever brand or type of air conditioner you have, we can service your system and check that it is operating as it should.
Having your air conditioner serviced before summer can help identify issues before they become a problem. It can also help your system operate efficiently and reduce the risk of an unexpected breakdown when you need cooling most.

It’s always great to hear from our clients and to share their stories.
Our Specialists Care
“Tony was friendly and professional from our first phone call for a quote and has been nothing but excellent throughout the process of quoting and replacing our ducted heating and cooling system. He was able to source a system within our budget and suitable for the size of our unit. On the day of install his team worked quickly and efficiently to get it done in a matter of hours and they were all so friendly and respectful in our house. Could not recccomend him more”
