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.

James D.
Gokhan and Louis did an amazing job installing my air conditioner! We had them install a split system in our bedroom, and couldn’t be happier

Their communication was excellent - explained the whole process and were very helpful and accommodating. The little things like helping to test different power mains to find the best configuration, the care they took to cover up and move my furniture, and the spotless cleaning job they did afterwards really set them apart. They even gave us a small gift bag at the end, which was a nice touch.

Highly recommended to go with this company, they are professionals through and through!
Nikki M.
I had a great experience from the first time I called with my initial enquiry until the completion of my installation. Excellent communication, customer care and follow up communications. I felt that I was being looked after throughout the entire experience. All of the technicians and tradesmen were very kind and extremely professional. I was kept updated throughout the installation. My place was left clean and tidy. I highly recommend this company - thanks!

Update - latest review for the Electrical Safety Inspection on 29/12/25 and Electrical Work on 07/01/26.

We are very impressed with Joshua, Vash and Mohammed. So, we are giving each one of them 5 stars.  Joshua was very detailed and very systematic when he conducted the safety inspection last 29/12/25. Also, giving us practical tips about safety and to monitor the old power points. He also patiently explained the importance of getting the electrical system and smoke alarm up to code and all the things that needs to be replaced. He is also courteous in his behaviour and how he engages with us.

Vash and Mohammed arrived early for the electrical work on 07/01/26.  These young blokes are very thorough, they know what they're doing. They worked as a team and non-stop for several hours. They are also impressive, respectful, and polite. Before they left, they double checked everything and even vacuumed the dining chairs and floor to keep thing tidy. We learned a lot from them and how to use electrical extensions safely.

These young men ( Joshua, Mohammed and Vash )will go far. They arrived neat, clean looking and ready to do the job. They have a high standard in workmanship, dedication and most importantly they have the right attitude about their work and how they treat us.

Kindly let them know that even though they might think they just did the electrical work. For us, they did more than that, they contributed to our health and safety.

Please, don’t stop inspiring these young men to continue developing their trade. They are the kind of professionals that our society needs. Thank you. Jennifer from Macquarie Fields.

Updated my review to include our recent service experience October 11, 2025 with Gabriel.

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.

ACC was thorough and professional on their quote and their installation was all completed ahead of schedule. They made an effort to minimize the mess caused by the work and their cleaned up and hauled away all packaging. The AC has made our house a home!
Karim M.
Charles and Aaron arrived on time and were patient and professional while answering all of my questions. They provided clear, written quotes, explained exactly what was included and what wasn’t, and even suggested and implemented a solution on the same day for a problem that wasnt even part of the job they initially came out to do.
Maria M.
Extremely impressed with Shaby, Michael and Benjamin from Alliance. Professional AC installation work, polite and friendly and very helpful. I would highly recommend these guys and the costumer service team from Alliance .
Helena M.
From the very beginning I knew I would receive good service from this company. The lady that answered the phone ( Kayley I believe) was very efficient in assessing what I needed and organising a supervisor to come in and arrange quote. That was Alex - he was very straightforward and a very good salesman!! The service itself was also straightforward with two techs coming in (Mitiesh and Nick) and they just got on with it while dealing with a very curious pet! Overall a very positive experience and I will be signing up with them for regular maintenance and refer the company for anyone who has a similar issue that I had. Thanks
Anne B.
We were very pleased with the whole process. Thank you.
William B.

Had new AC units installed and an old one replaced. My experience with ACC and their team was fantastic from start to finish. The team that supported us included Liam, Vash, Will, B.J, Theo and Jun. Cannot thank them enough for being such a pleasure to work with. They were incredibly professional, good at what they do and showed great care in helping us with our installations. I would highly recommend ACC and this team! Thank you to the Team again!
Christopher W.
I recently had air conditioning installed by Alliance Climate Control and couldn’t be happier with the experience. From start to finish, the service was outstanding.

A special mention to Vy, Luan, and Eric, who did an exceptional job on the day. They were professional, punctual, and clearly took pride in their work. The installation was carried out efficiently, with great attention to detail, and they left the place clean and tidy afterward. They also took the time to explain everything clearly and made sure the system was running perfectly before they left.

Highly recommend Alliance Climate Control to anyone looking for quality workmanship and excellent customer service.

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.
