FAQ

What is the difference between Single Phase and Three Phase models of Ducted, Ceiling Suspended and Ceiling Cassette systems?

The power supply to the premises. A single phase has one power supply (standard) whereas a three phase has 3 power supplies. In general, residential premises use single phase and commercial premises use three phase, however three phase can be installed in your house. Each model is made to suit each application. To find out what application you require contact your local dealer.

What is the difference between High Static and Medium Static Ducted systems? What does the heating and cooling capacity (kW) mean? How can I ensure that my air conditioner is properly maintained to operate efficiently all year around? Do I need a Ducted System in my house? What size air conditioner do I typically need to meet the cooling and heating needs for my home? Who can I speak to about selecting the right air conditioner for my home? Where do I go to buy an MHI air conditioner? I want to replace my old air conditioner. Should my replacement be the same size? Where should I place my air conditioner in the room? How long will it take to install an MHI air conditioner? What is the installation process if I’m building a new home? Why is it important to hire a licensed installer and what type of license do they need in Australia?

The installation process for air conditioners involves both electrical and refrigeration work, which is why it is important to have a licensed installer. In Australia, only a registered ARCTICK (Australian Refrigeration Council) Installer and an A-grade electrician should be used. Your 5 year parts and labour warranty will be voided if your system is installed by an unlicensed installer.

I am buying a new ducted system to replace the old one that I currently have. Can I use the existing ducts with my new system?
