Replacements
What is involved in an air conditioning replacement?
We check your current system and home, recommend a replacement of the right type and size, and send a written quote. On the day we decommission and remove the old units, install and commission the new system, show you how to use it and clean up. Our own electricians handle the electrical connection.
A replacement is a chance to fix what you did not like about the old system. Rooms that never cooled properly, a noisy outdoor unit under a bedroom, or a controller nobody understood can all be sorted out with better sizing, placement and zoning. We upgrade your comfort and efficiency while keeping to your budget.
We replace ducted systems, split systems and multi-head systems, and change homes from several split systems to one zoned ducted system.
Warning signs
What are the signs your air conditioner needs replacing?
Frequent breakdowns, an ageing system, rising power bills, rooms that never reach temperature, loud or grinding noises, and musty air that cleaning does not fix. A major failure such as a compressor on an older unit is often the deciding point, because the repair can cost a large share of a new system.
- Frequent breakdowns. If you are calling for repairs more than once a year, the money may be better spent on a new system.
- Age. Systems get less reliable as they age, and parts for older models can be slow or impossible to get.
- Rising running costs. An older or worn system uses more power to do the same job. A jump in your bill is often the first sign.
- Not keeping up. If rooms never reach temperature even after a service, the system may be worn out or too small for the space.
- Excessive noise. Loud banging, rattling or grinding from the outdoor unit can mean the compressor or fan motor is near the end.
- Poor air quality and smells. A system that stays musty after cleaning, or has a corroded coil, is often due for replacement.
- Major failure on an old system. A failed compressor or circuit board on an older unit is often the point where replacing makes more sense.
Not sure? Book a repair visit. If the system is worth fixing, we fix it. If it is not, we tell you and quote the replacement.
Benefits
What are the benefits of upgrading your air conditioning system?
A modern, correctly sized system is cheaper to run, quieter, more comfortable and more reliable. You also get a fresh warranty and the option of smarter zone control. Over the life of the system, lower running costs and fewer repairs go a long way towards the cost of the upgrade.
Lower running costs
Modern inverter systems vary their speed to match the load instead of switching hard on and off, which typically uses less power.
Better comfort
Correct sizing, zoning and room sensors give steadier temperatures and fewer hot and cold spots.
Quieter running
Newer indoor and outdoor units are generally much quieter than systems from 10 or more years ago.
A fresh warranty
5 years parts and labour on the units plus our 10-year workmanship guarantee, once the job is paid in full.
Cleaner air
A new coil and fresh filters, with the option of a UV air sanitiser on ducted systems.
Smarter control
Upgrade to ZoneTouch or AirTouch 5 to control zones and temperatures from your phone.
Efficiency
Is a new energy-efficient air conditioner worth it?
Usually, if your current system is old, oversized or undersized, or running most days. Newer inverter systems match their output to the load, and a properly zoned ducted system only conditions the rooms you are using. Compare the Energy Rating labels on the models we quote to see the difference.
The biggest savings come from getting the basics right: the right capacity for the home, insulated ducting, zones you can switch off, and a controller that holds each room at a sensible temperature. AirTouch 5 adds a temperature sensor in each zone, so conditioned air only goes where it is needed.
Ask us whether any government rebates or incentives currently apply to your replacement; they change from time to time. You can also spread the cost with finance.
Peace and quiet
Will a new air conditioner be quieter than my old one?
In most cases, yes. Indoor fans, compressors and outdoor fan blades have become much quieter, and inverter units spend most of their time running gently rather than starting and stopping at full power. Placement matters too: we position the new outdoor unit away from bedrooms and neighbours where the site allows.
- Better sleep, without a noisy unit cycling on and off through the night
- Quieter living areas, so you can hear the TV and each other
- Less noise for neighbours from the outdoor unit
- Fewer rattles and vibrations from worn mounts and panels
Don't suffer through another hot summer with an old, noisy system. Ask for a replacement quote or call 1300 101 100.
Good questions
Frequently asked questions
Can you replace my ducted system and keep the existing ductwork?
Sometimes. We inspect the existing ducts, outlets and return air on site. If they are in good condition and sized correctly for the new system, they may be reused; if they are damaged, undersized or poorly insulated, we recommend replacing them. See ductwork replacement and repairs.
Do you remove the old air conditioner?
Yes. We decommission the old units, recover the refrigerant under our ARCtick authorisation (AU064493) and take the old equipment away as part of the job.
Will the wall need patching when a split system is replaced?
It can. A new indoor unit may be a different size or shape to the old one, so a patch of wall that was covered may show. Plastering and painting are not included in our quotes unless they are listed, so we point this out before we start.
How much does an air conditioning replacement cost?
It depends on the system type, size, brand and how much of the existing installation can be reused. Send us photos of the current units and their labels, and the address, and we can usually quote without a visit. Quotes are valid for 21 days. Finance options are available.
Can I change from split systems to ducted?
Yes. Many replacements are a change from several split systems to one zoned ducted system. We remove the old splits as part of the job.

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.

A massive thanks to Frost Solutions. We got a 16kw ducted system put in with 7 zones and 9 outlets. Tyrone and the team were super friendly and very professional doing an awesome job, even helping me to keep maximum space in our roof so I could do an attic room. They also decommissioned and removed 2 of our old split systems. Could not recommend them more highly.

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 :)
