There are plenty of options to keep you and your family warmer in winter months. Some options are more versatile than others such as reverse-cycle ducted systems.
It all depends on your preferences and requirements. Here are some questions you should ask in preparation for an installation quote:
Energy Efficient

Rooms Required
How many rooms require heating in your home? This can open up more options that are more cost effective.
Size of Area

Getting an AC system sized to your home is important so your system isn't overworked.

What Our Community Is
Saying About Alliance
Excellence
based on 1500+ reviews
True to their word, Alliance Climate promised that if anything was scratched or damaged during installation, they’d fix it afterwards. Sure enough, Giannis reached out and came by to repair and paint everything back to good-as-new.
This guy is fantastic, he patched up everything perfectly!
Thanks again, Giannis, and thanks to the whole Alliance Climate team for standing by your service! 👏
We’ve just had our 5-zone ducted system plus 2 split units installed, and my wife and I couldn’t be happier with the result. Previously we had a gas heating system installed by another company, and it wasn’t done satisfactorily. The difference with Alliance has been night and day.
What really stood out to us was the strong team feel — they work seamlessly together, communicate clearly, and talk you through each step of the process. They also came up with excellent ideas to maximise the efficiency of our units.
A big thank you as well to James Greene, who provided the initial quote. He was highly professional, patient with our questions, and came up with a plan that matched exactly what we were hoping for.
Needless to say, my wife and I will be recommending Alliance Air to anyone looking for air conditioning installation — an outstanding experience from start to finish! 🌟
Throughout their visit they maintained this high standard and displayed a polite demeanor addressing all my queries with effective solutions.
I specifically want to express my gratitude to Shazim and his associate. His dedication to providing excellent service did not go unnoticed and is greatly appreciated. Thank you for providing such a professional environment.
The initial inspection by Jake was prompt, thorough and very informative. He answered all our questions clearly and offered us the various options in a format that was easy to digest.
Once we locked in our desired option, we were happily surprised by how quickly we were able to lock in a mutually suitable installation date.
The installation team led by Garrett were top notch! Daniel, JJ, Harry, Qais, Aden and Vish were all excellent, professional and meticulous at doing the job to a high standard. The team was quick to find solutions when issues arose, left the place spotless and ensured that the job was completed in 1 day which minimised any inconvenience to our usual work schedules...
We highly appreciated that they have an in-house team of various trades (plastering, electrical...) to handle any unexpected or anticipated collateral issues that might arise during the installation process.
The system is working great so far and we are super pleased with our choice!
Highly recommend choosing Alliance for installing your air con!
We struggled getting appointments from other HVAC vendors who came in and gave us estimations that were completely out of sight and then with the assistance of Catherine, we were able to schedule, a fantastic appointment with Alex, which resulted in a new system and installation the following day by an incredibly professional and meticulous installation team
No need to search for any other trades, this one is the best and don’t settle for less!
I want to share our recent experience with Gabriel, who provided a complete tune-up and service on our Fujitsu multi system last October 11, 2025. Overall, our experience was outstanding. My husband and I truly appreciate Gabriel’s dedication—his professionalism, expertise, and meticulous care stood out throughout the visit. He walked us through the air-conditioning health report, clearly explaining the tasks he completed and the performance of our air conditioner, while also offering practical and easy-to-follow maintenance suggestions that put our minds at ease.
Gabriel consistently demonstrates professionalism and a positive attitude toward his work, just as he did in January 2022. His respectful and polite manner made the entire process enjoyable. Thanks to Gabriel’s thorough service, we feel much more at ease knowing our air conditioner is in top condition and our home’s air quality is supporting a healthy lifestyle.
We are happy to recommend Gabriel to others, and we hope to see him again in another year or so. Thank you once again for your excellent service—Gabriel is truly deserving of 5 stars. Thank you, Gabriel.
----------------------------------------------
On the 19th of Jan 2022 an inspection was conducted by Gabriel. He was punctual and did a thorough inspection. He came back with Bailey for the AC cleaning and tune up on the 21st of Jan as per agreement. We have rated both of them 5 stars for the following reasons and base on our observations. Punctuality, tidy in appearance and work, very knowledgable with their trade, well mannered, they did a meticulous job in servicing our AC. Most of all, they were both efficient because they worked as a team. We are a very happy customer. Thank you Gabriel and Bailey.
Unfortunately, I've had my air conditioner for almost a year when it started leaking a few weeks ago. It was quite troublesome, especially with summer just around the corner. Thankfully, Alliance was quick to respond and handled the issue promptly and effectively. Yasin arrived, inspected everything carefully, and fixed the root cause of the leak. His confidence and quick thinking not only eased our worries about the upcoming summer but also helped us stay comfortable through unpredictable weather.
Overall, their support after the initial service truly reflects their commitment to helping customers. No installation is ever perfect, but knowing that Alliance was there to support us and get us ready before summer speaks volumes about their dedication. If I could, I’d gladly give them another 5-star rating! ⭐️⭐️⭐️⭐️⭐️

Thank you once again to the team at Alliance Climate Control. This was one of the smoothest home renovation projects I've experienced.
My previous air conditioner was a complete nightmare after installation—I bought it from a certain large electronics store that handed off the job to unreliable third-party contractors. Within months, it started leaking from the base and couldn’t drain properly, it was angled weirdly. It became one of the most stressful events for me, especially during summer when we relied on the air conditioning. The constant repairs and cleaning added up quickly in both time and costs.
When I finally surrendered and started to do my research i came across Alliance Climate Control. They not only promised to fix the issue but also ensure me they will install a new air conditioner the right way (they even stated this on their website - where they will make sure you are satisfied will their work before they finish). So when the team arrive, Kevin and Dragan took on a challenging job—my old unit was installed in an awkward position, with improper drainage and poorly done piping within the walls. But they were undeterred. They assessed the setup carefully, discussing how to best resolve the issues rather than just doing a quick install and leaving.
Their attention to detail was impressive, and they left my place spotless after the job, ensuring I wouldn’t have to clean up after them. safe to say - my room is now cool and ready for the summer heat!
The takeaway here: don't go with just any third-party installer. Air conditioning installations are complex, and cutting corners can cost you more in the long run. Alliance Climate Control's high ratings speak for themselves—they know what they’re doing.
Thanks again, Kevin and Dragan—I truly appreciate all your help!

Frequently Asked Questions
What is the best heating system on the market?
The best heating systems in the market is entirely based on your preference and your home’s requirement.

What type of heating system is right for my home?
There are several factors to figure out what the best heating system is most suitable for your home.
These includes:
- Your budget
- Functionality of the AC
- Any allergies/respiratory concerns
- The amount of rooms
- The size of the rooms
Our air conditioning technician can provide you with a complimentary, obligation-Upfront Quote to identify the best air conditioning for your home or business. This includes a heat load calculation, space inspection, and efficiency study.
Why do I need to service my heating system, it's just a filter clean?
IF IT AIN’T BROKE, DON’T FIX IT” – You’ve heard this saying before, correct? This philosophy doesn’t apply to mechanical devices that can actually breakdown, like your air conditioner.
Gas heating maintenance should be done every year around the same time and not on a ‘need basis’. This is the best way to keep malfunctions and costly repairs at shore. If you neglect your air conditioner system and skip maintenance, much like your regular dental check-ups, there is a higher chance of it breaking down early or needing major gas heating repairs.
Often more than half of your energy bills comes from heating and cooling appliances, so it only makes sense to keep your air conditioning working efficiently as possible. In fact, research found that proper and regular maintenance of your air conditioner improves efficiency and reduces energy bills by up to 35%. Plus, most importantly, you and your family will be breathing in consistently health and fresh air circulated from the system.
Senior HVAC Technician Josh – “An air conditioning service is not just a filter clean. It is a full system health check and maintenance covering the indoor unit, outdoor unit and interconnecting services. We strip, clean and inspect each part of the system then test and record all the data on a health report sheet for future reference. The idea is to get the system running as efficiently and clean as possible to save the customer money on running costs and improve the hygiene in their home.”
Why do you need to a heat load calculation before my installation quote?
Is there an after-care service?
We do have an after-care maintenance agreement which comes in three and five years where your air conditioning’s recommended yearly maintenance is sorted.
This annual service will make sure that the effective functioning of your system is maintained.
Plus, when you sign up for the maintenance program you will also be entitled to an extended warranty on the installation.
