FAQ

What does the heating and cooling capacity (kW) mean?

The heating and cooling capacity of your AC is measured in kilowatts (kW). Kilowatts measure the amount of energy output that occurs during operation. AC units that have a larger kW capacity can heat or cool larger spaces.

What does reverse cycle mean? What is R32 refrigerant and what impact does it have on my energy bills? How can I ensure that my air conditioner is properly maintained to operate efficiently all year around? What is the difference between Single and Multi Split systems and which do I buy?

A Single Split system air conditioner consists of one indoor unit connected to one outdoor unit and can only effectively heat or cool one room. A Multi Split system can connect multiple indoor units to one outdoor unit and can be used to heat or cool multiple rooms. To determine which one you should buy contact your local dealer who will help you decide which option best meets your needs.

For my family house, what type of an air conditioner should I buy?

When choosing an air conditioner you need to consider a number of different elements including, the size and shape of your room, the orientation of your house, the number of windows and the direction they are facing, as well as the style of your house. All these factors can impact the type and capacity air conditioner you should purchase. Get in contact with your local dealer today who will help you determine the best system that meets your air conditioning needs.

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 replacing the old air conditioner. Can the existing piping be used for my replacement system?
