Repairs
What air conditioning repairs does Frost Solutions do?
We diagnose and repair split, multi-head and ducted systems for homes and businesses: systems that will not start or cool, refrigerant leaks, water leaks, electrical and circuit board faults, noisy fans and compressors, zone motors and controllers. Minor fault or major repair, we find the cause first and quote before we fix it.
Our technicians are licensed and ARCtick authorised (AU064493) to handle refrigerant, and our own electricians can deal with the electrical side of a fault. That means one visit can usually cover both the refrigeration and electrical sides of a fault, without waiting on a second trade.
Why Frost
Why choose Frost Solutions for air conditioning repairs?
Because we fix the cause, not just the symptom. Our technicians inspect the whole system, test it properly, explain what failed and why, and give you a price before any work starts. If a repair is not worth doing, we tell you, and help you choose a replacement that suits your home and budget.
Diagnosis and troubleshooting
A thorough inspection and proper testing of refrigerant pressures, electrical supply, sensors and airflow to pinpoint the fault.
Repair or replacement
Quality parts and a clear recommendation. When a system is beyond economical repair, we say so and quote a replacement.
Replacement optionsRegular maintenance
Scheduled servicing prevents most of the breakdowns we see and extends the life of the system.
MaintenanceUrgent breakdowns
A system failing in a heatwave is urgent. Call us Monday to Friday 7am–4pm or Saturday and Sunday 9am–4pm and we will get a technician to you as soon as we can.
Ductwork problems
Disconnected, crushed or torn ducts and faulty zone motors cause hot and cold rooms. We repair or replace them.
Ductwork repairsController repair and replacement
Faulty wall controllers and sensors cause uneven cooling and wasted power. We repair them or upgrade to ZoneTouch or AirTouch 5.
Smart controlsRepair hours
When can you come out to repair my air conditioner?
During our business hours: Monday to Friday 7am–4pm, and Saturday and Sunday 9am–4pm. We are not a 24/7 service. Call 1300 101 100 in those hours and we will book the earliest available technician. Outside them, send an enquiry and we will call you back when we open.
Being honest about hours matters. We would rather tell you when we can actually be there than promise a midnight call-out and leave you waiting. Summer heatwaves are our busiest time, so if your system is showing early signs of trouble, book it in before it stops completely.
Safety first. If you smell burning, see sparks or scorch marks, or water is near electrical parts, switch the system off at the isolator (usually beside the outdoor unit) or the circuit breaker, and leave it off until a technician has checked it.
Causes
What are the most common reasons air conditioning systems fail?
Most failures come back to a few causes: no regular maintenance, blocked filters, refrigerant leaks, electrical faults, iced or dirty coils, failing fans, faulty controllers, blocked drains and age. Many of them can be prevented with servicing and caught early if you act on the first warning signs.
- Lack of maintenance. Without regular servicing, dirt builds up and worn parts go unnoticed until they fail.
- Dirty filters. Blocked filters choke airflow, so the system runs harder and hotter than it should.
- Refrigerant leaks. A slow leak reduces cooling and, left alone, can damage the compressor.
- Electrical faults. Loose or burnt connections, tripped breakers and failed boards stop the system starting or running properly.
- Frozen indoor coil. Poor airflow or low refrigerant can ice the coil, which stops it cooling the air.
- Dirty outdoor coil. Leaves, dust and salt on the outdoor coil stop it getting rid of heat, which raises running costs.
- Fan problems. A failing fan motor or damaged blades reduce airflow and can overheat the system.
- Controller and sensor faults. A faulty controller or temperature sensor can stop the system turning on or off at the right time.
- Blocked drains. A blocked condensate drain backs water up into the unit, causing leaks and mould.
- Age. Older systems break down more often, and parts can become harder to find.
Regular maintenance and prompt repairs prevent many of these problems. If your system is not behaving normally, don't wait until it fails completely.
Problems we fix
What air conditioning problems can you fix?
Systems that blow warm air, rooms that cool unevenly, new noises, short cycling, sticky humid air and refrigerant leaks are the problems we see most. Each has several possible causes, so we test before we replace anything, and explain what we found.
Not cooling or blowing warm air
Often a refrigerant leak, a compressor or capacitor fault, a dirty coil or blocked airflow. We test the system to find which.
Uneven cooling between rooms
In ducted systems this is usually a zone motor, a damaged or disconnected duct, a blocked filter or a sensor fault. We find the cause and fix it so each room gets its share.
Strange noises
Rattling, banging or squealing can be loose panels, a worn fan bearing or a failing compressor. We track down the source and repair or replace the part.
Turning on and off frequently
Short cycling can come from a sensor or controller fault, dirty filters, low refrigerant or an electrical issue. We diagnose it so the system runs normally.
Humid, sticky air
A system that cools but leaves the air clammy may be oversized, low on refrigerant or have airflow set wrong. We work out why and recommend the fix.
Refrigerant leaks
We find the leak, repair it, then pressure test and recharge the system with the correct amount of refrigerant. See leak repairs.
Unit types
Which types of air conditioner do you repair?
Split systems, multi-head systems and ducted systems in homes, plus commercial systems such as ceiling cassettes. Before we book a repair we ask for the make and model, and a photo of the unit and its label, so we can confirm we work on that brand and bring the right parts.
Licensed and warranted
Will a repair affect my manufacturer's warranty?
Not when it is done properly. We hold an ARCtick refrigerant trading authorisation, and each type of air conditioner has its own service requirements, so we work to the manufacturer's guidelines. If your system is still under the manufacturer's warranty, we tell you, because the repair may need to go through them.
Systems we install come with a 10-year workmanship guarantee covering the gas charge and call-outs, 10 years on duct and pipework, and 5 years parts and labour on the units. If we installed your system, let us know when you call so our office can check your warranty first. Warranty details.
Good questions
Frequently asked questions
Are you available 24/7 for air conditioning repairs?
No. We answer calls and attend repairs Monday to Friday 7am–4pm, and Saturday and Sunday 9am–4pm. Outside those hours you can send an enquiry and we will contact you when we open. If you notice a burning smell, sparks or water near electrics, switch the system off at the isolator and keep it off.
Is there a call-out fee for a repair?
If we did not install the system, there is a call-out fee to come out and find the fault, and the repair is quoted once we know what is wrong. If we installed it, tell us: it may be covered by our warranty, and our office will sort it out.
Which brands do you repair?
Tell us the make and model when you call, and send a photo of the unit and its label if you can. We will tell you straight away whether it is a brand we work on. Note that "Mitsubishi" could be Mitsubishi Heavy Industries or Mitsubishi Electric, so check the label.
Should I repair or replace my air conditioner?
If the system is fairly new and the fault is a single part, repair it. If it is old, breaking down often, or the repair would cost a large share of a new system, replacing it usually makes more sense. We will give you both options honestly. See air conditioning replacements.
What should I check before I call?
Check the controller has power and is set to cool or heat, the batteries in the remote, the circuit breaker at the switchboard, and that the filters are not blocked. If none of that helps, note any error code on the controller and call us.
My air conditioner is leaking water. What should I do?
Turn it off, put a towel or bucket under the leak and call us. It is most often a blocked condensate drain. Read more on air conditioner leak repairs.

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 ...
