What Type Of Air Conditioner Is Best For Me?

There are plenty of choices for air con installation in Sydney to keep you and your family comfortable year-round. There are some fantastic options on the market for reverse-cycle ducted air conditioning systems, keeping you cool in the summer and warm through winter.

The right system for you all comes down to your personal preferences and what you need from an air-con system. When you speak to the air conditioning specialists at Alliance Climate Control for a quote or installation, here are some questions to keep in mind.

Want energy efficient air con that is cost-effective long term?

It’s important to be aware of all the benefits and functions of the air conditioning system you are installing because installation costs can be very different from the cost to run. Some systems may come with a higher initial investment cost but cost less to run and save you money over time. Air conditioners that are cheaper to install might cost more over time through running costs.

How many rooms need cooling in your home?

The number of rooms that need air conditioning will be one of the single biggest factors influencing what system you install. The size of those rooms, their capacity and how efficient the airflow in that room needs to be will also end up affecting your decision. The more rooms that need air conditioning, the more options become available to you for large scale systems that are both energy and financially efficient, albeit with a higher initial investment.

What is the size of the area that needs cooling?

It’s not uncommon for smaller systems to be installed in Sydney homes to avoid higher initial costs for air conditioning installation. However, a system too small for the house it’s installed in will quickly be overworked and result in more frequent breakdowns. Like most things, having the correct sized system for your the is key to ensuring it runs effectively, with as few issues as possible.

Do you or your family suffer from allergies, asthma or other respiratory issues?

When your air conditioning system affects so much of the air you breathe in your home, it’s vital to choose an air conditioner with a proper filtration system. It’s especially important for your system to deliver clean, pollutant-free air for people with any sort of respiratory illness. For your convenience, here at Alliance Climate Control, we provide and install a range of allergy-friendly air conditioning with filters rated to capture up to 90% of particles and irritants found in the air.

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!
Ovi D.

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 🙏
Jason
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.

Split System Air Conditioning Installation

Split system air conditioning is the standard type of air cooling that many homes have. The split system is made up of two components, the indoor cooling unit and the exterior heat exchanger.

The exchanger sits outside the home, dispersing the heat evenly to not interfere with plants or affect people and animals. The indoor cooling unit is what most people imagine when they think of air conditioning, a cooling unit that can be easily changed via the remote.

Split cycle air conditions have many benefits as a method of home temperature regulation. Split system air conditioners are quiet and cost little to operate. Due to the grilles that circulate the air, split system air conditioners can direct and send air anywhere in the room much easier.

Many modern models have remotes that act as a focal point for the air conditioner, focusing air wherever the remote was activated for better accuracy than manually adjusting the grilles.

Ducted Air Conditioning Installation

Ducted air conditioning is a luxurious way to cool your entire home. Installed in the roof, ducted air conditioning features tubes that disperse cool air from a central location through the tubes to vents in each room that sit seamlessly on the roof of various rooms.

The ability to zone ducted air conditioning is the biggest appeal for many customers. Ducted air conditioning zoning allows you to group groups of rooms to cool them without cooling the rest of the home.

For example, grouping bedrooms separately from the rest of the home lets you keep bedrooms cool in summer overnight while people use them without cooling the rest of the house. With the ability to pick and choose which zones are cooled at any time, you cut down on your power bill by no longer regulating rooms that aren’t in use. 

Custom Air Conditioning Installation

Here at Alliance Climate Control, we offer a range of air conditioning solutions for custom and variable-sized locations where more traditional styles of air conditioning are less efficient.

Multi-split air conditioning, for example, is a great way of air conditioning homes with multiple floors, office complexes and multi-level buildings. This type of system is often the right choice due to its ability to match the needs of its environment.

If some rooms need drastically different temperatures, it’s able to adjust without compromising on energy efficiency.

We also have a range of Variable Refrigerant Volume (VRV) units available. These systems are the best choice for institutions with more significant amounts of people, for places like hotel lobbies, hospitals and convention centres.

A VRV system differs from other systems because it works based on the size of the room that needs to be cooled. The system consists of an indoor and outdoor unit that work together to provide a consistent room temperature that is achieved more quickly, using less energy, than other systems.

Evaporative Cooler Installation

Evaporative air conditioning is quite common and has built a name for itself as an excellent choice for home cooling solutions. This is due to its initial price point and overall running costs.

Evaporative air conditioning utilises a damp evaporative pad and distribution fans to harness the hot and dry air outdoors, pass it through the wet evaporative pad, and then circulate it around your home as cool air.

Evaporative air conditioning is often regarded as the most environmentally friendly home cooling option. Because it harnesses the fresh air outside the home and doesn’t use any refrigerant gasses, it uses far less electricity than other systems.

This type of air conditioning system allows it to cool open areas, not requiring doors and windows to be shut like other air conditioning systems. Because they use less power, they end up being far more cost-effective.

Frequently Asked Questions

There is no such thing as the “best air conditioning system.” Air conditioners aren’t a one-size-fits-all solution because every home, budget, and location is unique. Contacting our team at Alliance Climate Control is the simplest way to determine the best system for your home and situation. We can calculate your heat load, inspect your space, and conduct an efficiency study to recommend the best system for you.

Your budget, the size of your home, and the number of rooms you want to cool all influence the best air conditioning system for your home. You’ll also need to pick an air conditioner brand, each with its own set of advantages and disadvantages. You can always contact our team at Alliance Climate Control to help you with this process. Our knowledgeable staff will assess your home and make recommendations for a system that will work for you.

To ensure that your air conditioning system functions properly, you should have it serviced regularly. Cleaning the air filter alone won’t be enough. An air conditioner, like any other machine, requires routine maintenance to ensure that it operates properly, efficiently, and safely. A minimum of one service per year will significantly extend the system’s lifespan and reduce the number of breakdowns you’ll have to deal with.

When it comes to determining what air conditioner you need, the size of your home isn’t the only factor to consider. Direct sunlight, roof height, machines, and residents all contribute to the ambient heat in your home, affecting how hard your air conditioner must work to keep your home cool. Our knowledgeable staff can perform a heat load calculation to determine which air conditioner will fit into your budget while not racking up a large monthly bill.

We are happy to offer an aftercare service to all of our customers at Alliance Climate Control. Our aftercare service includes the yearly maintenance that your system requires to keep it running at its best for as long as possible.
