What Is A Split Wall Air Conditioning System?

Split system air conditioners are a popular choice for Sydney residents looking for reliable heating and cooling solutions. With two separate units, an indoor and outdoor unit, hot and cool air can be efficiently directed as needed throughout your home.

Essentially, the indoor unit has an evaporator coil that cools down the room according to your set temperature. Meanwhile, the outdoor unit contains a condenser coil, which heats up outside air to be blown into the house through ducting. This is known as reverse cycle air conditioning, which is a major benefit to split systems.

Interested in installing heating and cooling functions into your Sydney home with just one system? Get in touch with the experts at Alliance Climate Control today to enquire about a split system air conditioning unit.

When it comes to HVAC services, Alliance Climate Control prides itself on going above and beyond for all of our customers. Sydney residents looking for split system air conditioners can also access all necessary services in one convenient place.

Check out how our dedicated team can help you today!

Installation

In their search for split system installation, Sydney residents may come across multiple HVAC providers. Few are as motivated to provide tailored and timely care as Alliance.

Locally-trained and licensed technicians are available across Sydney to install your choice of split system air conditioners. We handle all of the work, leaving you confident in the knowledge that our installation team will leave your home just the way it was, now with an added AC system.

With an on-site assessment of your home, we can recommend the best system for the household’s needs. Whether that’s an air con unit that prioritises low running costs, or one that features extensive filtering for allergy-prone occupants.

Find your best match in split system products and installation services with us.

Repairs

Have you noticed your split system air conditioner experiencing some issues during operation? Uneven cooling, leakage, loud noises, or even bad smells? These can all be signs that your system requires a professional assessment and repairs.

Without timely intervention, your system’s lifespan can be greatly reduced as HVAC issues build up. This means more costly repairs, greater electricity bills, or the need to completely replace the air conditioner

Ensure year-round comfort by scheduling an appointment with the experts over at Alliance. We have the skills and knowledge to identify any problem your split system AC may be experiencing, as well as resolve it promptly.

Replacement

When your current air conditioning unit can no longer reliably perform, even after professional repairs, it may be time for a replacement system.

Alliance handles all of the work that comes with removing an existing AC and getting a split system installed. With our expertise, we can have your home tidied and your new cooling systems operating in just one efficient appointment.

No need to break your own back by disposing of your old unit, either. We also take care of the recycling of broken-down ACs, including offering all Sydney residents access to rebate discounts. Save more time and money by bringing in the experts for your AC replacement service.

Cleaning

Keeping split-system air conditioners operating at peak performance requires more than maintenance. It also means scheduling an annual clean from HVAC specialists to remove any blockages and prevent high heat loads on crucial components.

Without a regular cleaning, issues such as coil freezes, water leakage, poor energy efficiency, and reduced airflow capacity can become apparent. That’s why Alliance provides a thorough Eco-Clean service that only uses environmentally-friendly products; we prioritise both your AC and the environment.

Maintenance

It’s highly recommended that your split system air conditioner undergo an annual check from an HVAC professional. Without regular fine tuning, small issues can build up over time, potentially leading to an inconvenient and costly breakdown.

Alliance ensures each maintenance appointment ends with our local team leaving behind more efficient systems than we entered with. This is achieved with thorough examinations of your split system air con and its components; both within the indoor and outdoor units. Then, we take care of any work required to restore your system to its peak performance.

Alliance Climate Control technicians are ready to mobilise and waiting on your call. It’s time to set up your annual appointment with a technician now!

Split System Air Conditioner Brands We Partner With

Why Install a Split System Air Conditioner in Your Home?

Unlike most other air conditioning systems, the split system design strongly aligns itself as a heating and cooling unit, adaptable to any climate across Sydney. Otherwise known as reverse cycle split systems, this product is commonly installed by Sydney residents since it’s an all-in-one package for dealing with summer and winter.

You can easily distribute clean, comfortable air around your home or business with a split system air conditioner. However, other notable benefits of installing these reverse cycle systems include:

  • Quiet to run and less intrusive to install than ducted air con
  • It’s cheaper to install a split system air conditioner than a centralised system
  • Built-in filters help keep your air clean and pure
  • Energy-efficient operation, especially with the latest models
  • Sleek, stylish and modern designs that suit every home or office
  • Reverse cycle heating and cooling that can be zoned to specific rooms
  • The durability of the outdoor unit and the simplicity of the indoor unit make maintenance fairly easy

How Much Does A Split System Installation Cost?

Multi-Split-System-2

Generally, the cost of split system installation is low. This is because it’s less invasive than ducted air conditioning to install, and you can end up paying much less if there are fewer areas you want to cool.

However, split system installation costs vary greatly depending on the number of rooms you have and how large they are. For example, a typical three-bedroom home, with one living room and one multi-purpose room, you could be paying anywhere from $4,500 to $6,700 to place split system units in all rooms.

At Alliance Climate Control, we have technicians who specialise in split system installation. No matter where you are in Sydney or Greater Sydney, we strive to provide highly tailored and customised quotes for split systems – just give us a call to book an appointment with one of our technicians today!

Fantastic team and great work on replacement system install. 👍 Huge thank you to Qais, Louis & Christian.
Guy M.
Great all-round service from Alliance! Communication was timely from Will and Chris in the office, and Liam, BJ, Theo and Nic were great to deal with for the job quote, service, and install. The install required access to my neighbour’s property, he also commented that they were incredibly polite—asking to move pots and putting everything back exactly as it was. Highly recommend!
Lance L.
Good, professional installation, very happy.
Innes P.
As usual, a pleasure to work with the team, installation went well with the team completing the work in the time they said they would, and following up when needed.

All very tidy too, with everything, even the old fans taken away - great work, thanks Charles and team!

Allianz climate control were great! Super detailed and thorough service of our ducted air conditioning for about 2hrs on site. Cristiam the technician was awesome 🙏

We recently had our ducted air conditioning system replaced and couldn’t be happier with the experience. Their current google rating really reflects their level of service, From start to finish, the team delivered excellent customer service and made the whole process seamless.

Everyone we dealt with — VJ, Eric, Brody, Mosd, Harry K and Ionnaes — was friendly, knowledgeable, professional and always punctual. They were respectful of our home and took the time to explain everything clearly, which gave us a lot of confidence in their work.

We really appreciated the trusted advice provided throughout — it never felt like a sales push, just honest recommendations tailored to what we needed.

The operations were also very well organised. From the initial booking, through to installation and final payment, everything ran smoothly and on schedule.

Highly recommend this team if you’re looking for a reliable and professional air conditioning company.
M. G S.
The air conditioning service was outstanding. The technician arrived right on time, communicated clearly throughout the visit, and provided helpful information after the job was done. He serviced the equipment thoroughly and professionally. Couldn't be happier with the experience—highly recommended!

Update. March 2026

AGAIN! We had an outstanding experience with Alliance Climate Control, thanks to Gabriel & Nicolas.

They were extremely professional from start to finish; quickly diagnosed and resolved all of our air conditioning issues with confidence and precision. What really stood out was how informative they were, I was clearly explained the problems, the solutions, and how to prevent future issues.

The attention to detail, efficiency, and friendly approach made the entire process seamless. It’s rare to come across someone so knowledgeable and genuinely committed to great service.

A huge thank you to Gabriel and Nicolas; outstanding service.
Gail G.
Service is fabulous. Great customer service. Professional and very competent technician. I would recommend without hesitation.
Martin B.
Charles, James, Aden and JJ arrived on time and completed the installation in an exemplary professional manor. I would recommend the team to anyone. Cheers to you chaps.
Benjamin C.
I contacted Alliance Climate Control, due to leaking water from my air conditioner. I had Gabriel come to evaluate the condition, and he gave me quotes and explained options. He immediately scheduled the job through a phone call with the office. 2 weeks later, I had Emre and Luke come to my apartment to properly do a deep clean on my air conditioning system. They both did a fantastic job within 2 hours. After the AC is properly cleaned. It works perfectly and feels like new again. Really happy with the job they did. I think I'm going to do this every 12 months as they recommended.
Bill S.
The team led by Bokhan did an excellent job on the installation. They worked through the bad weather to get the job done, and were always ready to provide us feedback when needed. The instal team and the electrical team were very professional.
We would highly recommended Alliance Climate Control for their high quality work.
Helen C.
Dylan and Connor were punctual, professional and a pleasure to deal with. Painstaking in their work, they did an excellent job servicing my airconditioning unit.
Alison H.
Great service. Damon & Brendan arrived on time, worked quickly, explained everything, tidied up. Thank you!
Tim A.
Superb service - Ivan and hist team worked assiduously all afternoon to provide everything and more that I asked for - well beyond the call of duty! He and his team were receptive, polite and just got on with it. The best service I have ever had in fact.
Iva S.
Gokhan, Can and Niko have installed our new AC and removed the old one. Professional, kind, polite and very respectful. They cleaned all rubbish and packing materials from the works. They left the area clean and all the works have been done with good workmanship. Very careful with our belongings. Happy with the installation. Electrical works are still ongoing.

Edit to add the electrical installation- Mohamed and James were amazing. The job was very long, but the persevered and did a very nice neat conduit. They cleaned up after drilling and the cut offs- very neat work and great quality. Very polite and professional.
AC works ! Thank you for your services, would not hesitate to use ACC crews again.

I had a second job done by ACC - amazing electrician Mohammad and cannot fault his work. Always checking when things got tricky 😅 but we solved all the issues on the spot. He replaced our 24 years old main switch board and created 2 new outdoors el sockets. Neat, tidy, polite and very efficient. Even our cat liked him ☺️. Thank you for your service!
Helen C.
Excellent service, punctual and extremely thorough and helpful.
Michelle P.
I was happy with the service from Alliance through the whole process. Harry spent a alot of time at our house discussing the various options for aircon (ducted vs. Split systems) and the pros and cons of each - he even tried to find the manhole access to our roof. He was also very responsive to questions I had about the quote once we'd made a decision.
BJ and Carlos came for the install. They were very professional, did a good job of cleaning up afterwards, and spent time explaining the whole install process and how to use the systems once they had left.
I would use Alliance again for any further aircon installation. I was really happy with their service and the quality of the work.
Alborz R.
I had a fantastic experience with the entire team who installed my air conditioning system. From the initial coordination to the final installation, everything was handled professionally and smoothly.

A big thank you to BJ, Theo, Can, Matthew, Cara, Eric and Will — each of them was knowledgeable, friendly, and clearly took pride in their work. The team arrived on time, communicated clearly throughout the process, and left the place clean and tidy after the job was completed.

Highly recommend this team to anyone looking for reliable and professional air conditioning supply and installation. Couldn’t be happier with the result.

P.S. Andre returned to install the wooden aircon cover—fantastic job, great energy, and super efficient. Really appreciated it!
Rodney M.
Very professional. Great company. Efficient.
James T.
We are so very pleased with the installation of our new system. Kevin, Dragan and Ivan were so professional, thoughtful, with every aspect of the installation. Kevin’s instructions to me re the control pad were very clear with him constantly checking that I understood all aspect of the control panel. Their clean up and the way they left our home on completion was just perfect.
Kevin, Dragan and Ivan are a credit to your company, we feel very fortunate to have had three such competent team members of Alliance Climate Control carry out our requirements.
Pauline R.
I can't speak too highly of the service we received from Alliance. From first contact and ongoing attention from Cara and Luke in the office to the assessment stage with Steven, the service was courteous and efficient, answering all our questions without hesitation.
When it came to installation B.J. and Theo were very prompt and helpful, taking great care to ensure that we were well informed and happy about every stage , leaving us with written directions and a demonstration of how to use the controller.
We have no hesitation in highly recommending Alliance.
Nat C.
Thanks Aden and Ryan for your amazing work and leaving the place so tidy afterwards.
Mark C.
Stephen, Rahul and Alex were all very professional and did a fantastic job on our system. Highly recommended
Gael H.
Dylan phoned 30 minutes before arriving. He was clean, very efficient, knowledgeable and thorough. He patiently walked me through the timer process and left written directions. We kept him longer to answer questions. He did not tear out the door.

Susan D.
I was so lucky to get my annual service by Christian. He is a dream technician to work with. He was punctual, polite, accommodating, listened to my requests and fulfilled them all. Worked every minute whilst he was here, made photos and texted them to me, when I needed to know what condition the roof was in. His work was very clean, he did a very thorough job, got photos of "before and after". I couldn't be more satisfied with him, I'd like to get him back any time. I can recommend him to all your customers. Congratulations to the all your management who make excellent effort to pick the right people, who, in the end, just enhance the reputation of the company. Well done!
Ros R.
I have already given a feedback by phone that said how pleased I was with the teams efficiency & work ethics of Jonathon, Christian & Ca. They did a great job! Rosalyn
Alex B.
We had our system installed by Alliance a few years ago and everything about the experience was clear, professional with great results. Even now on the fixed price servicing, it’s predictably good, great value. I can’t recommend Alliance Climate Control enough. Thank you.
Ella F.
Dylan did a great job servicing our AC's! He was punctual, friendly, efficient and explained everything really well.

Frequently Asked Questions

Each HVAC brand brings unique benefits and features to your home through split system ACs. So, the perfect choice for you may differ greatly to another resident due to your different lifestyles and household needs.

However, Alliance partners with some of the most reliable brands in the Australian market to efficiently power your climate needs. This includes well-known brands such as Mitsubishi Electric, Daikin, Fujitsu, and many more.

Installation of any HVAC system, including split system air conditioners, generally doesn’t require a plumber. Rather, a HVAC specialist like those at Alliance are needed for a professional and reliable install.

The answer as to which is cheaper is entirely dependent on what type of Australian home each system is trying to cool or heat.

For example, ducted air conditioning systems are generally used for larger homes, hence usually costing more than split systems. However, running a multi-head split system may cost just as much or more if used for several rooms.

Discuss which may be the more cost-effective option for you with Alliance.

For some Australians, the following factors may be considered a disadvantage of split system air conditioners:

  • The need to install an outdoor unit and then multiple potential indoor units where airflow is desired
  • More complex installation processes than some other air conditioning systems
  • Indoor units are often more visually obvious than ducted systems
  • Limited operations in larger-scaled rooms or an open space
  • If the outdoor unit experiences a problem, all internal functions will also stop
