Split system air conditioning
What is a split system air conditioner?
A split system is a reverse cycle air conditioner in two parts: an indoor unit on the wall of the room and an outdoor unit outside, joined by refrigerant pipes, a drain and a cable. It heats and cools one room or area, with its own remote, and is the most common way to air condition a single room in Australia.
On the Gold Coast, a split is the go-to for bedrooms, open-plan living areas, home offices, granny flats and units. It is quick to install with little disruption, and you can add more over time. The four headline benefits are energy efficiency, area-specific cooling, easy installation and improved air quality, explained below.
Why choose a split
Why choose split system air conditioning?
Split systems are efficient, because you only condition the room you are in, and comfortable, because each unit has its own temperature. They are simple to install, filter the air, come in several styles and run quietly indoors because the compressor sits outside. For one to a few rooms they cost less than ducted.
Energy efficiency
You cool or heat only the room you are in, when you are in it. Modern inverter splits ramp up and down to hold the temperature instead of cycling on and off, which keeps running costs down.
Comfort where you need it
Each indoor unit has its own remote and temperature, so a bedroom can sit at a cooler setting than the lounge. Several splits in one house give you room-by-room control.
Simple installation
A split needs a wall for the indoor unit, a spot outside for the outdoor unit and a short pipe run between them. It suits existing homes, extensions and new builds alike, with little disruption.
Cleaner air
Every indoor unit has washable filters that catch dust and lint, and many models add finer filtration. Cleaning the filters regularly keeps the air fresher and the unit efficient.
Flexible design
Choose a wall-mounted unit, a floor console, or a ceiling cassette or bulkhead unit where wall space is short. We help you pick the style that suits the room.
Quiet operation
The compressor and the main fan sit outside, so the indoor unit only has a quiet fan. Most models have a night or quiet mode for bedrooms.
Who it suits
Who is split system air conditioning for?
Split systems suit homeowners who want to cool and heat a few rooms, investors adding air conditioning to a rental, and small businesses such as shops, offices and cafes. If you want the whole house conditioned from one system, ducted is usually the better fit.
Homeowners
Cool and heat the rooms you use most, such as the main bedroom, the lounge or a home office, without paying to condition the whole house. A good choice for smaller homes or as a top-up to an existing system.
Investors and landlords
A cost-effective way to add air conditioning to a rental. Splits make a property more comfortable for tenants without major building work, and each unit is simple to service and replace later.
Small businesses
Shops, small offices, consulting rooms and cafes can condition the spaces customers and staff actually use. For larger fit-outs, see our commercial air conditioning service.
Running a business? For bigger spaces or several tenancies, see commercial air conditioning and ceiling cassette units.
How it works
What are the components of a split air conditioning system?
A split system has an indoor unit and an outdoor unit. The indoor unit holds the evaporator coil, a fan and the filters, and cools or heats the room's air. The outdoor unit holds the compressor, condenser coil and fan, and moves the heat outside in summer or brings it in during winter.
Indoor unit
Mounted high on the wall, the indoor unit draws room air through its filters, passes it over the cold (or hot) coil and blows it back out through adjustable louvres. Moisture removed from the air drains away through a condensate pipe, so placement and drain fall are part of a neat install.
Outdoor unit
The outdoor unit sits on the ground, on a slab or on a wall bracket. It needs airflow around it and enough clearance to service. Near the beach, salt air attacks the coil, so a sheltered spot and corrosion protection help it last.
Pipes, drain and cable
Insulated copper pipes carry refrigerant between the units, alongside the drain and the power and control cable. We run them as neatly as the building allows, in a cover or through the wall, and keep the run as short as sensible.

Split system questions
Frequently asked questions
How much does a split system cost to install on the Gold Coast?
It depends on the size and brand of the unit, how far the pipes run between the indoor and outdoor units, wall construction, whether the outdoor unit goes on the ground or a bracket, and the electrical work. We give a written quote, valid for 21 days. See current options in our split system shop, or ask for a quote.
What size split system do I need?
Sizing depends on the room's floor area, ceiling height, insulation, windows and which way it faces. A small bedroom may need a small unit, while an open-plan living area with west-facing glass needs much more. We size each unit for its room rather than guessing, so it is neither undersized nor wasteful.
Can you replace my old split system?
Yes. We remove and decommission the old indoor and outdoor units, recover the refrigerant, and install the new system, reusing the existing location where it still makes sense. See air conditioning replacements.
Is a split system or ducted air conditioning better?
A split system suits one to a few rooms and costs less up front. Ducted air conditioning suits whole homes, with one discreet system and zoning. If you want several rooms but have no roof space for ducts, a multi-head system runs several indoor units from one outdoor unit.
What warranty do I get on a split system?
Our 10-year workmanship guarantee covers the gas charge and call-outs, our pipework is covered for 10 years, and units carry 5 years parts and labour (Hisense 5+2 years). Warranties apply once the job is paid in full. Warranty details.
How often should a split system be serviced?
Clean the filters every few weeks when the unit is in heavy use. A professional service checks and cleans the coil, fan and drain and tests the system; how often depends on how hard the unit works and whether it is near the coast. 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 ...
