Which split systems can I order through the shop?
The shop lists two split system ranges: Hisense and Mitsubishi Heavy Industries (MHI). Both are wall-mounted reverse cycle split systems that heat and cool a single room, and both are supplied and installed by our own licensed team. Open a product to see the sizes and install options, then send an enquiry.
Hisense Split System
Value wall splits for bedrooms, living rooms and rentals. Hisense units we install carry 5+2 years parts and labour. Price on quote.

Install
We walk through the unit positions with you, install, test, show you the controls and clean up.
Pricing
What affects the installed price of a split system?
Five things move the price most: the unit capacity, whether it is a new install or a replacement, single or double storey access, how far the outdoor unit is from the indoor unit, and whether the outdoor unit sits on a wall bracket or a concrete slab. We ask about each one so the price we confirm is the price you pay.
| Option | Choices | Why it matters |
|---|---|---|
| Unit capacity | 2, 2.5, 3.5, 5, 6.3 or 8 kW | Matched to the room’s size, sun and ceiling height. |
| Install type | New install or replacement system | Replacements include removing the old unit; existing pipework is checked before reuse. |
| House type | Single or double storey | Upper-floor units can need longer runs and more access work. |
| Pipe run | Back-to-back or long pipe run | Back-to-back means the outdoor unit is directly behind the indoor unit, which is the simplest install. |
| Outdoor mounting | Wall bracket or concrete slab | Chosen for space, access, drainage and noise. |
| Install day | Monday to Saturday | Tell us your preferred day and we will confirm availability. |
Other options
What if a single split system is not enough?
If you want to cool several rooms, compare a multi-head system, which runs several indoor units from one outdoor unit, or ducted air conditioning for the whole home. Our ducted aircon packages are the starting point for whole-home quotes.
Every system we install, split or ducted, carries our 10-year workmanship guarantee and 5-year parts and labour on units. Warranties apply once the job is paid in full. See our warranty.
Good questions
Shop questions
Can I buy a split system online?
Not with a cart. Every split system we sell is supplied and installed by our team, and the price depends on the install, so you send an enquiry and we confirm a fixed price before anything is booked. Nothing is charged online.
Why is there no price on the shop?
The unit is only part of the cost. The size, the pipe run, how the outdoor unit is mounted, single or double storey and whether an old unit is removed all change the price, so we quote each job rather than show a figure that may not apply to you.
Do you sell units without installation?
Our shop is for supply and installation by our licensed team, which is what our warranty covers. Call us if you have a different job in mind.
Which other brands can I get?
The shop lists Hisense and Mitsubishi Heavy Industries, but we also supply and install Daikin, Samsung, Fujitsu, Mitsubishi Electric and Panasonic split systems. See all air conditioning brands.

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 ...
