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.

What Our Clients
Are Saying About Alliance

Peter Biasotoo
From the time I contacted Alliance to the completion of a new ducted gas heating system I have nothing but praise for the company and its staff. Initial inspection was done by Jake Who provided me with the quote and confidence to proceed with the job. Their office did follow up to coordinate installation date and time of the arrival by the guys doing the installation.

The courteous and professional approach by Jonathan Thomas Sam and Peter is a credit to them as representatives of Alliance and having dealt with many contractors in my career and by comparison they are up there with the best, as individuals and as a company in the industry. I would be most pleased to recommend the company and its staff to any body that wishes to contact me.
Ted Robinson
I don't think I've ever come in contact with a better-run business than this one. From the first inspection to talking through the options right through to installation this mob was stunningly professional - they always turned up on time, communication with the office was perfect, all the documentation was excellent; whoever runs this business really needs to be congratulated. Then on the day of the installation, an unpleasantly hot day to be working up in the roof, they sent three excellent young blokes - Harry, Aaron P. and Aiden, who did a really great job.

I recommend these guys without hesitation; I'll give my sister in Crows Nest a ring and proselitize today as I sit back and enjoy a day when 33 is forecast, rather than suffer through it.
Andy Taylor
The guys who quoted and installed our a/c were absolutely fantastic. The instal was not an easy one but Andres, Ivan and Asa worked quickly and efficiently, installing our ducted reverse cycle system.

They were very polite, neat and tidy and very professional. The system works really well and we are very happy. This is the second time we have used Alliance and we highly recommend them.
Jason
The Alliance team were excellent from first contact through to quote and installation. I couldn’t be happier with the service. Everyone I have dealt with has been super friendly and courteous. The installation team arrived on time, calling half an hour before arrival.

Work carried out was explained clearly prior to commencement and I was consulted on any predilections. All care was taken to ensure my furniture was protected from dust caused by drilling, and clean-up was performed brilliantly after completion. It was a big job, however the team were always professional and considerate, taking great care with the installation and the overall aesthetics. I was so impressed with the service that I am now scheduling my next installation. Highly recommended.

Thanks to B.J. Noah, Adrian, Tory, Zac, Joe, Charlene, Sam.
Patrick Reeves
We sort 4 quotes to replace our old ducted system with a new Daikin Zoned System. Two quotes were $3k more than Alliance Climate Control, one was cheaper, but they did not appear to be very professional and wanted to install in the easiest manner which would have left a strip of conduit running down our wall to the control panel.

Michael and his team from Alliance CC were able to replace our existing unit with the minimum amount of change to our existing set up. They were very competitive, they were professional in there manner, they took care not to tramp dirt through the house (on a rainy day), they turned up when they said. We are very happy with the new system, which is so quite compared to the old unit it replaced. I know of 4 other owners in our complex who (gained seperate quotes) have since used Alliance CC to change over their old units.
Kelly Cranko
I cannot praise Alliance Climate Control highly enough .

It is definitely one of the best companies I have dealt with in a long time.

I give it 5 stars for admin, professionalism , punctuality, helpfulness , neatness ... It was a pleasure to deal with them from start to finish. They even called me back on a Saturday afternoon when I could not operate the air conditioner (no fault of theirs) - they talked me through it and it worked within minutes . I would not hesitate to recommend them
David Fergusson
The Alliance team of Kevin, Andre and Dragan arrived on time and completed the heater installation work promptly and efficiently. The guys were cheerful, friendly and courteous. They worked effectively to overcome any obstacles found during the job. They were careful about cleaning up after the job and ensuring we were able to understand the operation and the follow on maintenance arrangements. Same comments apply to Tim who came during the installation and looked after the gas fitting work.

Thanks Tim, Kevin, Andre and Dragan for a job well done.
Anna Hu
We got our air conditioning installed by Alliance today and it completely exceeded our expectations.

Alliance was recommended in a local Facebook community group and from our first interactions they have been so professional and thorough. Zac was so knowledgeable and gave great advice on where we should install the units and Tommy and Nick installed the units over 2 days and we couldn’t be happier. Tommy and Nick’s work is clean, thorough and to such a high quality. We are just so happy and I highly recommend them!
Christopher Walton
Alliance Climate Control,

I would like to thank the entire Alliance team for an outstanding ducted air conditioning installation.

In particular, Goran for providing an immediate quote and scheduling, and the technicians Kevin, Dragan, Garret and Harry for their reliable, professional, cooperative and tidy work.

I would definitely refer Alliance to friends and colleagues for any air con needs.

Thank you for a job well done. Happy to be cosy once more. Cheers

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.

Based on 2025 reviews
Elle Jay Q.
We didn't go ahead with the quote, only because another company fitted our needs more closely, but I would still 100% recommend including Alliance as part of who you call when looking for aircon. Liam Doyle quoted us and he was very knowledgeable and friendly. I would definitely advise calling them if you need aircon.
Darby J.
From start to end excellent professional team, great communication, very well organised and coordinated, installation teamwork was superb, clean up was very well done.
James, Tommy, Matt, Miguel and Harry were all excellent, courteous and respectful of working in our house.
Overall they were a team that I would have back again and recommend to any future customers.
andre M.
Did what they said they would do very efficiently
Jennifer H.
The team were punctual, extremely polite and did a great job!
James H.
Andres, Ivan and Juan from Alliance Climate Control replaced two old air conditioners efficiently and timely. They were friendly and knowledgeable about the products and I highly recommend them.
Helen R.
It was raining heavily the day the Alliance Climate Control technician came to my house to provide a maintenance and check up for my two air conditioners. He carried out the job, working both inside and outside without complaint (about the rain). He was on time and efficient. I have confidence that he did an excellent job. Thank you.
Jay K
Dragon and his two mates were very polite and respectful, they drilled the wall from both sides to minimize the chipping, installed everything nicely, and completed the job on time. I am really pleased with them.
John M.
Good job.
Aaron J.
Wow! I called Alliance Climate Control to get some advice on my ageing air-conditioniers and from that moment on, it was a pleasure to deal with such a customer focused company. After emails / texts from Head Office explaining the process, Raj turned up to give me a diagnostic report on my almost broken air-conditioning system. After explaining all of the possible scenarios, I decided to purchase a new system. Team Leader Vy and Cristian turned up a couple of days later and from that point on, it was all systems go. Everything was explained simply and professionally as the process went along. Other technicians turned up ( Harry, James and Moller) to help with the installation (which at some points was more difficult than expected due to my ageing terrace house) and it was all carried out in an expert manner.
I would highly recommend Alliance Climate Control for any air-conditioning needs.
spencer B.
Great team very professional
Levi's D.
Kyle was very professional and courteous.
Kim
Alliance installed a Daikin 15.5Kw ducted unit one week ago. The team of Garrett, Lewis and Qais worked really well together. Qais was particularly impressive with his work ethics.
Also, Harry who did the plastering, and Yiannis who finished the job off with very careful painting of our ceiling.
Peter K.
Our old ducted air conditioner failed, so we contacted the team at Alliance for a replacement. They provided a competitive quote and completed the installation quickly. James Greene thoroughly explained the process and presented us with several options. Alliance offers exceptional before-and-after sales service, and we have enjoyed trouble-free air conditioning for the past two summers.
Michael W.
Tommy, Miguel and Nick did an excellent installation. Very tidy and neat.
Andrew L.
Alliance were outstanding from start to finish. Made an initial enquiry and James came out the next day. Comprehensive quote on the spot. Accepted and the whole install was done the following week - ducted system and two split systems. Install team of Yunus, Gokhan and Emre were outstanding - courteous, clean and knowledgeable - and worked hard. I'm a pedantic customer - and part of the house is very old - they were more than happy to be accomodating and sort any issues I raised. Very pleased with the quality of the work and the team - would highly recommend.
Rod W.
I needed to replace a reverse cycle central air-conditioning system that was about 20 years old and add a smaller new system in a different part of the house. I decided to use Alliance Climate Control after doing some research meeting their salesperson at my home in a very productive exchange.
Gerald B.
Special thanks to Tommy, Nick and Miguel for their excellent work
jessie R.
This was my second aircon clean and service from Alliance. Both times the techs were on time, pleasant, and knowledgeable. I wouldn't now use anyone else.
Peter H.
What a pleasant and professional service Alliance Climate Control provided. From the initial phone contact to the friendly, courteous, and efficient service provided. Alex arrived on time checked both units and kept me informed at all timers as to the best solutions. We then had BJ, Daniel and Brandon install a new Daikin unit. As mentioned when it was booked they covered furniture and did a clean install. Zac also deserves a mention as coordinating and ensuring a smooth operation made it seamless. Thank you Alliance Climate Control for making it an professional experience, highly recommend.
Scott K.
The Alliance Climate Control team, from engagement, quotation, installation and customer support was excellent. The ACC install team of Tom, Nick, Miguel, Matt, Benjamin and JJ were very professional in all aspects of the install and commissioning. Would most highly recommend ACC.
Inti R.
Tommy and Nick were absolute legends, they did an aircon relocation from my living room to my attic. both Tommy and Nick did the job with no fuzz, fast efficient and more importantly quietly. I was working from home through the job, and they needed little to nothing from me once they were setup and ready to go. The aircon was moved professionally. Thank you!
karen S.
Great service. Very professional. Highly recommend.
Mary J.
BJ,Daniel, Brandon Aysa, Zac Peter & Aden.
From the first phone call thru to quote job & clean up to showing me the easy to use remote. Have all been wonderful, professional installation fantastic & very thorough with prep, covering furniture and clean up afterwards.
This was a very considered purchase.
I'm so happy I chose to go with Alliance.
Philip M.
BJ, Daniel, Brandon, Chris Divis & Zac were all very professional the service we received was excellent. Highly recommend them. Good Job All Round.
Maurice N.
Outstanding staff. Punctual, clean, knowledgeable and efficient.
chi-kan W.
Your installation has been mostly excellent but very recently I noticed that the condensation has not been flowing into the evaporation tray. There is a short horizontal section of the pipe for discharging the water into the tray but the water, instead of dripping into the tray, tracks backwards and drips onto the floor. I have remedied this by attaching a plastic cone to that short horizontal section. In the future, ensure that the last short section of the pipe SLOPES into the tray to ensure that water doesn't track backwards.
Lia
A big job completed with ease and professionalism by ACC, so happy my place is now cool! From James Greene’s initial quote to the install team of BJ, Daniel, Brandon, JJ, Vash, Blade and Giannis, plus Zac and Eric and Will and Joe behind the scenes, everyone has been delightful to deal with. Highly recommend
Gennaro S.
Professional Team , efficient and very pleasant to deal with . Wonderful service by Tommy ,
Nick and Chris , Vash and Blade .
Brett D.
We have a two level house with 5 bedrooms 3 bathrooms lounge room family room and kitchen
We needed a system to do the whole house
I had two quotes both of which the gentlemen giving the quote were at my house for no more than 30mins.
Darko from Alliance came and was totally professional and inspected the house roof cavity and all. He then sat down with me and discussed the system that would best suited, he explained the installation process and how Alliance worked in all he was here for over 2 hours. It is because of Darko knowledge and commitment we decided to go with Alliance.
The installers arrived on time being Matt,Aaron,Mahalo and Andre. They worked here for 3 days putting in the system. We were totally impressed with the way they worked and the quality they delivered. They were also courteous, respectful and ensured they cleaned up after every day work. TRUE TRADESMEN

WE could not rate the people we have dealt with from Alliance Climate control, highly enough. From the time of quotation to the time of installation we were constantly informed of what was going on.

So from us its a 5 out of 5 for everyone involved from Alliance Climate Control in giving us a great Air Conditioned house
Sam D.
Great service options and very detailed work. Highly recommend

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.
