Which split systems are in this category?
This category has two ranges: the Hisense Split System and the MHI (Mitsubishi Heavy Industries) Split System. Both come in sizes from 2 kW to 8 kW, as a new install or a replacement, and both are installed by our own team. Prices are on quote, because the install changes the cost.
The basics
What is a split system air conditioner?
A split system has two parts: an indoor unit on the wall of the room and an outdoor unit outside, joined by refrigerant pipes, a drain and power cabling. It cools or heats one room at a time, which makes it a cost-effective choice for bedrooms, living areas, studies and granny flats.
Split systems suit homes that only need a few rooms air conditioned, and rooms that ducted air conditioning cannot easily reach. Read the full guide to split system air conditioning, or compare it with ducted air conditioning.
Choosing
How do I choose between Hisense and MHI?
Both are reliable reverse cycle wall splits. Hisense is usually the lower-cost option and carries 5+2 years parts and labour when we install it. MHI is a Japanese engineering brand with inverter units across the same sizes. If you are unsure, ask us to quote both for the same room.
We also supply and install split systems from Daikin, Samsung, Fujitsu, Mitsubishi Electric and Panasonic; they are quoted the same way.
Good questions
Split system questions
What size split system do I need?
It depends on the room’s floor area, ceiling height, insulation and how much sun it gets. A shaded bedroom needs far less than an open-plan living area with west-facing glass. Tell us about the room and we will recommend a size from our range of 2 kW to 8 kW units.
Is a split system reverse cycle?
The split systems we sell are reverse cycle, so they cool in summer and heat in winter from the same unit.
Can you replace my old split system?
Yes. Choose "replacement system" when you enquire. We remove the old unit, check whether the pipework and wiring can be reused, and install the new one. See air conditioning replacements.
How often should a split system be serviced?
Clean the filters regularly, more often if you run the system every day, and have it professionally serviced from time to time to keep it efficient. See air conditioning maintenance.

I have just had a total of 5 aircons fitted up by the boys at Frost. 4x brand new installs to each bedroom, and a new replacement for the lounge. I cannot fault anything. Their communication, punctuality, price and workmanship have all been superb throughout the entire process. Trouble and stress free. Its easy to see why they have so many 5star reviews. True professionals. Thanks again.

Absolutely fantastic experience with Frost Solutions! I recently had a ducted air-conditioning system installed and honestly, from the very first conversation through to the finished installation, the whole process was seamless. ... The installation itself was done to a really high standard, the team worked efficiently and left everything clean and tidy. ... Great people, great communication, great workmanship and a great result.

Couldn't recommend Frost Solutions highly enough. We recently had them install a 16kW Daikin ducted system with 8 outlets, 6 independent zones, AirTouch 5, multiple upgrades and a 5 year service plan. ... Another big positive is that Frost Solutions have their own electrical team as part of the installation. ... the entire experience was seamless.

Frost Solutions installed ducted air conditioning in my home today and I couldn't be happier. The team were professional, friendly, punctual, and down to earth. ... left the house spotless ... I also really appreciated the follow-up call from the office later in the day to check I was completely satisfied ... They're a local business with local staff, and the value was extremely competitive for the quality of service and workmanship provided.

From my initial phone call to the pre-check and installation, all correspondence and actions were clear and understandable (for someone who is non tech savvy).. Shout out to Paul (Senior Technician) ... He was also clear when showing me how to use the air-con, and info on future servicing and cleaning when needed. Thanks Frost Solutions Team, I highly recommend you to anyone needing a new aircon :)

Wow! Frost Solutions is possibly the best all round company I've worked with for a long time. The admin staff, sales and tradesmen-installers were all very polite, efficient and easy to communicate with. From the time I phoned to organise a quote to the full install was only an about a week ...
