Commercial Heating and Cooling

What is a Commercial Air Conditioning
System Installation?

Installation of a Commercial Air Conditioning System is the most energy efficient way to keep clients, guests and employees comfortable. A ducted Commercial Split or Multi-Split system can deliver clean comfortable air to different parts of your office, public building or retail area. Different set temperatures can be maintained in different zones, compensating for varying comfort levels or frequently opening doors.

For larger open areas such as restaurants, theatres or convention facilities, ceiling cassette or suspended ceiling systems may be employed. Each of these systems, often twice as powerful as conventional split or multi-split residential systems, feature variable compressor load sensing and energy saving features plus temperature and motion sensing capabilities that will shut down the system if no movement is detected after a set period of time.

Each of these systems share a common operating principle in that an outdoor unit, housing the compressor and finned condenser coil, supply pressurised refrigerant gas to the respective indoor unit. This indoor unit houses the finned evaporator coil and fan blower, together with an air filtration medium to ensure air entering the conditioned space is clean and comfortable.

However, a ceiling mounted cassette system is able to deliver air in a 360° arc in more than 20 different configurations and is particularly suited to long narrow rooms, “L” shape or irregular shaped spaces.

A suspended ceiling system is more suitable in regular shaped spaces with higher ceilings up to 4.3 metres high. It requires no intrusion into the ceiling cavity and has alternating air flow capabilities in both vertical and horizontal directions.

Both systems, manufactured by reputable companies such as Daikin or Fujitsu, ensure compressor output meets cooling demand rapidly, yet consume the least amount of energy necessary.

Once the set temperature is achieved, compressor output is automatically adjusted to maintain the required temperature. Sensors monitoring temperature or movement in the conditioned space, trigger the compressor to provide more cooling or to shut down if no motion is detected.

Why is a Commercial Air Conditioning System Installation?

Similarly, the outdoor unit comprising a robust cabinet, only requires a location providing clear air, a stable footing base and a supply of electrical power. In the case of large installations, multiple units are able to be located close together if needed, with the provision, sufficient space is provided according to the manufacturers recommendations for suitable heat dissipation and service access.

Commercial Air Conditioning System Service

Regular service of commercial air conditioning systems is critical to ensure continued operation at peak efficiency.

Alliance Climate Control recommend regular services at least once every 12 months with an Eco-clean service to the finned coils every alternate year.

Regular inspections and services are easily completed by our fully trained Daikin and Fujitsu service technicians, generally without impact on your operation. Such inspections are an invaluable tool to highlight any matters requiring further attention, or to prevent costly unplanned repairs or frustration.

Conventional Split, Multi-split may be serviced directly at the installed wall unit in the conditioned space. Ceiling cassette systems are serviced within the ceiling cavity, whilst suspended ceiling mounted systems may be serviced entirely from beneath the unit, ensuring clear access to all components.

Alliance Climate Control annual service inspections are designed to keep your system operating at peak performance all year round.

Regular service inspections include, making sure the compressor, drive motor and other critical components are operating correctly, checking both finned coils, fan blowers and filters are clean. Monitoring refrigerant pressure and sensing function operation.

Analysing these processes, Alliance Climate Control’s trained technicians are able to identify the likelihood of future maintenance requirements or malfunctions before they might occur.

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 coils to eradicate any dust, dirt or dangerous pathogens.

We will also check the ducting and air entry grilles to make sure they are clean and sealed properly ensuring you get the most benefit from your commercial air conditioning system.

What are Commercial
Air Conditioning System Repairs

Air conditioner systems consistently operate effectively when airflow paths remain free from obstruction and normal operation of major components is enabled. To ensure this is achieved and to maintain satisfactory operation, regular system servicing should be completed at least every 12 months by Alliance Climate Control technicians, trained to service Daikin and Fujitsu products and skilled to identify any signs of future concern.

However, by contrast, poor maintenance of the filtration system or an absence of whole‑of‑system service schedules may allow dirt build up to reduce cooling airflow, or allow poor operation of other critical components to remain unchecked, ultimately causing the compressor and other critical components to operate under greater load which may cause premature failure.

Whilst such repairs may be untimely, frustrating and expensive, Alliance Climate Control’s technicians have the ability to repair or replace the required components rapidly, accessing replacement parts from a vast warehouse of readily available spare parts.

Furthermore, a complete a check of the entire system will be made to ensure each and every component is operating to factory specification. They will also complete a performance check of the refrigerant gas pressure and ensure air at each outlet is delivered at verified temperature and air volume levels using accurately calibrated instruments.

Why are Commercial Air Conditioning
System Repairs necessary?

Repairs to Commercial air conditioning systems are usually required when system components fail to operate correctly. Unfortunately, this is often when the system is operating under severe conditions such as unusually hot days or after a particularly windy and seasonally dusty period or in other words, at a time when they are most needed to perform well.

In addition to resolving system problems and performing required repairs to commercial air conditioning systems Alliance Climate Control will ensure your entire system is restored to a condition as close to “as new” as is possible.

Original Review:
I had a split air con unit installed in my apartment by Alliance last week. Yunun and his team did a fantastic job from start to finish. They were friendly, professional and ensured that the unit, compressor, cabling and ducting was installed neatly and blended in with the surroundings. They left my apartment in showroom condition after they finished! I couldn't be happier. Highly recommended.

Update – April 2026:
Andre G came out to complete the annual maintenance on my aircon under job #105771, which Alliance installed last year. The unit was particularly dusty inside, and Andre carried out a thorough service and deep clean. He was professional, meticulous, and explained each step clearly in advance. He did a terrific job and left the apartment spotlessly clean. Thanks again to the Alliance team for consistently great service.
Nina F.
The technicians were on time and professional, they did a really good job deep cleaning our AC units which were very dirty and blocked by molds causing water dripping. I am happy that my ACs was fixed and working well now.
Jacinda M.
2026 - Kyle and Nikola came for my yearly service. They were a pleasure to have. Very professional and did such a good job! I wish I could give them 20/10 stars

Great experience! All the staff are extremely professional. It’s obvious the company has invested a lot into tech and their process to give a great customer experience. Special mention to Gabriel, BJ and Zac for their help!
JJ F.
Very good experience with Alliance Climate Control.

Ivan led the team with Mosa, Zac and electrician Mohamed. Two split units installed and condenser placed neatly at the back.

Process was smooth from start to finish. Clear quote, easy scheduling, no surprises. They arrived at 7:15am and finished by 3pm.

Old heritage terrace, not an easy job. They adapted on site and improved a couple of original decisions. Final result is better because of that.

Workmanship is clean. Conduits through the roof cavity are tidy, indoor units fit well above the windows, and the outdoor unit is discreet.

Ivan communicated clearly throughout and set everything up on our phones at the end.

Professional team. Good execution. Would highly recommend.
stefan W.
Alliance is an amazing company. I thought professional service like this had disappeared years ago. Not only that - but all team members really know their stuff. From the initial sales call with James to comms with the office, booking the day doing the install and cleaning up afterwards everything went like a training movie. How do you get everyone on the same page??? All I can say guys is thank you for an outstanding job - I'd hate to be your opposition.
Joey L.
I had the team from Alliance (Aysa, Vi, Nikola, Eric, Harry, Aiden and James) put in aircon at my apartment. The whole process was great from start to finish. They were professional, punctual, tidy and very friendly. Highly recommend!
Lachlan
The team at Alliance is excellent.

Their knowledge and service lead to an install that was a day shorter and significantly cheaper than quoted. This was completely unexpected after another local company couldn't be bothered to tell me my project was beyond their skill level and ghosted me without providing a quote.

Jason was able to avoid cutting into our ceiling which was amazing after preparing ourselves for a significant patch and paint job.

They are professional, fast and everyone I had contact with was eager to help.

If anyone even slightly mentions air con or an aircon issue I'll be recommending Alliance.
David H.
Alliance Climate Control were a pleasure to deal with. Really professional & a smooth experience from start to finish. I was really happy with the installation team - Qais, Louis & Callum did a fantastic, neat job & left the place immaculate. I asked for a minor change to the drain lines and they were very accommodating.
Stephen K.
Excellent professional service.
Turned up on time, knowledgeable technicians.
Lily L.
We recently had a new ducted air conditioning system installed by Alliance Climate Control and couldn’t be happier with the experience. Liam was the first to attend our home when our 20-year-old system failed. He took the time to thoroughly assess the situation, explain our options clearly, and provide a very competitive quote. His friendly and professional approach made the whole process easy and stress-free from the start. On installation day, Vy and his team were great. They were punctual, efficient, and kept us informed throughout the entire process. They took care to keep our home clean and made sure everything was working perfectly before they left. Overall, the service was outstanding from start to finish. We really appreciated the professionalism, clear communication, and attention to detail. Highly recommend Alliance Climate Control to anyone looking for a reliable and high-quality air conditioning installation.
Leo N.
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.
Professional service, arrived on time and good communication throughout the appointment process

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.

The importance of business maintaining their air conditioning

Generally

As a business owner, the health of our staff and guests are our number 1 priority. Regular maintenance is done on all our air conditioning systems to make sure pollutants such as mould (black mould), dust, dirt, grime and viruses are eliminated.

Hairdresser, Barbers, Beauty Salons

Beauty salons and hairdressers uses several different types of products like hair spray, hair dye, bleach, hair dryers and other materials that releases pollutants into our indoor air. This may clog up your air conditioning systems and blow out pollutants back into your shop. This likely means your guests who spend hours relaxing in your shop will be breathing in all types of pollutants.

General, Dentist, Physiotherapy

As a health practitioner, we understand that you care especially for the health of your staff and patients. Many procedures and materials you use may block up the filters of your air conditioner. Blocked up air conditioner can contain viruses and pathogens that affects people with respiratory issues and allergies.

Furniture, Homeware & Decor

Any stores that burn scented candles or spray fragrances on a regular basis will likely have clogged up air conditioning systems, quicker than those who do not. This means that the air conditioner is not able to operate as efficiently before which likely means a larger energy bill is coming your way.

Pet Store/ Veterinary Hospitals

Having many animals around and visiting the building means extra pet dander, odours, and other animal pollutants. Maintaining your air conditioning regularly can make sure that the air conditioning is working efficiently and minimise the risk of early break down such as foul smells, rattling, and leaks.

Cafes, Greengrocers, Delis, Restaurants

Businesses that involves serving food and drinks should take extra care of their air conditioning systems. Although mould within air conditioners may not be as obvious as mould on a bread, it exists. This can produce an uncomfortable environment especially for families with respiratory issues and allergies.
