What is Residential Split and Multi-Split Air Conditioning System Service?

Regular service of Split and Multi-split air conditioning systems is critical to make sure they continue to operate at peak efficiency.

Regular inspections and checks on operating performance are easily completed by our fully trained Daikin and Fujitsu service technicians, generally without affecting the operation of the system or inconveniencing your family’s normal activities. Such inspections are an invaluable tool to highlight any matters requiring further attention, or to prevent costly unplanned repairs or frustration when major repairs become necessary.

Alliance Climate Control inspections keep your system operating at peak performance all year round.

We will make sure the compressor and critical components of the system are operating correctly, checking both condenser and evaporator coils, fan blowers, filters and condensate trays to clean and remove any dirt or dust build-up that may prevent efficient operation.

We also recommend an Alliance Climate Control Eco-clean service every two years to clean and service the finned coils incorporating a microbial treatment of the coil to eradicate any dust, dirt or dangerous pathogens for prolonged periods.

We will also check the ducting and air entry grilles to each room to make sure they are clean and sealed properly ensuring you get the most benefit from your Split or Multi-split air conditioning system.

Why are Split and Multi-Split Air Conditioning System Services necessary?

Split and Multi-split air conditioning services scheduled at regular intervals, make sure your system is working at peak performance, ensuring filtration mediums are free from dust or pollens that may prevent efficient cooling, damage system components, produce unpleasant odours, adversely affecting the comfort of occupants.

  • Temperature sensing and operation of the inverter compressor and other critical components ensuring consistent and desired air delivery temperature.
  • Build-up of dust or pollens in the fan, coil or filters and poor sealing of room entry grilles allowing ingress of dust or conditioned air to escape.
  • Low level of refrigerant gas. This may be perceived by occupants as inferior cooling efficiency further emphasised if air flow through the evaporator coil is poor or restricted causing extra load on the compressor.
  • Dust accumulation on fans or condenser coil may reduce the heat dissipation characteristics of the condenser coil, in turn putting extra load on the compressor when the condensing process is compromised.

How can we help with service of your
Split and Multi-Split Air Conditioning System?

Alliance Climate Control will help make sure your Split and Multi-split air conditioner system continues to operate consistently with optimum efficiency.

At regularly scheduled services recommended at 12 month intervals, we can check the operation of the indoor unit and room entry grilles to make sure all components are sealed properly and each unit working properly.

We can also check refrigerant gas pressure at various points within the circuit to verify optimal performance of the compressor, evaporator and condensation coils.

Additionally, we can also check the outlet temperature at each room entry grille against calibrated thermometers to ensure the desired air temperature is being delivered.

Each of these checks when completed on an annual basis will ensure your system is at optimum efficiency, providing you with maximum comfort. We also recommend an Alliance Climate Control Eco-Clean service every two years to make sure the finned evaporator coil remains clean and clear from bacteria.

Is Saying About Alliance

Based on 2259 reviews
Damon L.
Outstanding service! I called yesterday for a second opinion on our ducted gas heating, which had stopped working. Another company told us we needed to replace the entire Braemar unit for $6,000. Thankfully, Appliance Serviceman Gabriel took the time to properly diagnose the issue, cleaned the sensors, and had it running again — all for the cost of a very reasonable service call. His expertise, honesty, and excellent customer service truly made my day. Couldn’t be happier and highly recommend Gabriel!
Barbara L.
Matt with his team Aiden and Noah installed new aircon equipment for us. They were fast efficient, clean, tidy and hard working. They were also polite and friendly, explaining everything we wanted to know. I recommend them very highly.
Tristan C.
Couldn't be happier with the amazing service. Super quick turnaround (sent an email on a Monday night, by Wednesday it was sorted). Kody was super helpful and reasonable in diagnosing and quoting, then Emre tackled the pretty big job (took him hours) without complaint, and was super helpful in answering any questions we had and resolving an unexpected issue. Just top notch service and I can't imagine calling anyone else next time we need help with the AC units.
Michael J.
I was very pleased with the result. I booked a service call some weeks away, but got a call a few days later that an earlier time was available. Excellent. I took it. Kyle came on time, did the job very thoroughly. And he did not complain about parking in the area! Excellent again. I really appreciated the communication so that I knew when he was coming. I signed up for the future!

Three years on from the initial airconditioner installation and upgrading our external electrical board, I again needed Alliance to fix some old wiring inside the house and look at the air conditioner unit that had stopped working. Again, their service was great. The issues were tricky to fix, but I cannot fault their service. It was friendly, attentive and competent. Even more impressive was the follow-up of the technicians very early the next morning to make sure the air conditioner problem was fixed - and when it wasn't, they were straight back. Thank you to all who attended over those few weeks, including - Vishal, Andre, Christian, Peter, Steve, and young Andre. It's not yet fully resolved, but it's now a warranty issue with Actron - here's hoping they live up to the service standards of their dealer. Thank you Alliance.
avinesh N.
Good team of workers who care
Linley M.
Big thanks to Alex who did the initial quote and then Jason and Nik who came and completed the job. Company was efficient from the time of online enquiry through to quote and then servicing. Air con was well overdue for a service and is now working far better than before. Thanks team!
soheila M.
I had a fantastic experience. From the first phone call to the final installation, their team was professional, friendly and efficient. They explained everything clearly, gave me a fair quote and completed the job on time . The new air conditioning system works perfectly and has made such a difference in my home . I really appreciate their honesty , attention to detail, and great customer service. Highly recommend them to anyone looking for reliable air conditioning services. Thank you once again for everything
Kelly T.
Shout out to Tommy, Miguel and Chris for installing our new air con. The guys did a fantastic job and treated our home as if it was their own. Alliance is always fantastic with communication and calibre of work - will definitely be using them again in the future.
Katie B.
We are very happy with this installation. Alliance always came when they said they would. We think the quotation represented fair value. The work was done efficiently, there was no mess, everything was left so clean and tidy. The workers without fail were courteous and friendly, and quiet! Thank you to Tommy, Ben, Miguel and Chris, we are delighted with your work.
Paige
We had our heating/air con and all ducting completely replaced with Alliance - the whole experience was perfect! The 4 person team (Shadi, Adam, Sam and Bill) arrived exactly on time and went right to work. They were diligent about every aspect of the install and our house was cleaner when they left. Highly recommend for any heating/air con work!

Update: A few years later and we are still using Alliance for regular maintenance on our system. The team today (Dan and Nik) were very professional, efficient and tidy. I still highly recommend Alliance.
Martin C
Very professional service and expertise in air con installations
Robert K.
Very satisfactory job completed by Ivan; good attention to detail and explanation along the way. Also by Andre’s 4 days earlier
Robert M.
I was kinda nervous about tradies punching holes through our walls and screwing conduit to our externals walls, but these guys were great. Asked me lots of feedback prior to doing things, kept me informed, did a great looking job. Would recommend.
Asha J.
Ivan led a great install team who worked tirelessly in rain and sun to get the job done! Very happy!
Ms Chris T
My air conditioner technician Damon arrived at the appointed time, and expertly assessed the condition of my air conditioner. Gave the quote for a service, did the job in a timely manner.
Knowledgeable in his field of expertise, friendly professional manner. Happy my air conditioner is summer ready. Would highly recommend Alliance Climate Control.
Steve H.
Just couldn't improve the service! A really great team, from the friendly office contact Aysa, to the highly knowledgeable on-site consultant Will and then the considerate, hardworking installation team; BJ, Meedy and Charles A. You guys are a credit to the business and a great example of what expert customer service should be. Would highly recommend the Alliance Climate Control team to anyone considering AC installation
Therese Van W.

Very efficient and professional service from the team at Alliance. I would highly recommend for your Air Conditioning needs.
Deborah C.
I now have working central gas heater system after Brivis had been such a great system for me for the last 24 years. Lets hope I have another 25 years with no problems.
Mel S.
The team was friendly, efficient, and highly professional throughout the installation of our air conditioner. Everything ran smoothly, and we couldn’t be happier with the result. A special shout out to Jiayi Gino who managed the project and the team. Highly recommended!
Lisa H.
Vy, Luan and Kim spent two days replacing our out dated air-conditioning unit dealing with issues with the tight installation space. I was kept informed the whole time in any issues they had and they were really polite and respectful. They did a great job in cleaning up after they finished. Very happy with their work
Leslie B.
Jonathan, Peter, Adrian and JJ installed a couple of air conditioners at my home. Polite and professional, they consulted me at each decision point, offering options and recommendations during the installation process. I highly recommend them.
Update 15/8/25: while comparatively expensive to others, I think it's fair price given the quality and depth of backup service. I've had some issues with the units, but they were resolved. Recent servicing and support from Damon was was superb.
Jola S
Very happy with the quick turn around of a fairly complex job. The crew were friendly and very polite and explained everything clearly. Once the job was finished the clean up was thorough and they left my pace immaculate. Definitely would recommend the service
郭凯
Excellent work on site. Teams are very kind and good communication as well. The after job clean made my kids thought they were never been here.
Maurice N.
Outstanding staff. Punctual, clean, knowledgeable and efficient.
Bill P.
Excellent service and great communication by BJ, Christian,Peter, Blade , Harry, Liam, Will & Marion
John O.
Very happy with the A/C service provided by Alliance. Their service technicians are always polite, respectful and professional.
Anna & J.
The Team from Alliance were everything you need from trades. I was able to get an appointment within the week to assess what was wrong with air conditioning. Then when it came to installation they were flexible enough to shift the date due to wet weather which would have meant 5 days with no heating. Everyone was always polite and explained everything thoroughly. Site clean up was exceptional. I would Definitely recommend to a friend.
