What is a Multi-Split
Air Conditioning System?

A Multi-split system air conditioner is the most energy efficient way to bring the comfort of conditioned air to your family home, office complex or multi-level building.

The Multi-split system, comprising one compressor and condenser coil, housed in a robust cabinet positioned outside, can connect up to five indoor units individually set at different temperatures for varying comfort levels.

The compressor supplies sufficient refrigerant to each coil to achieve a maximum cooling rate at each indoor unit then automatically reduces refrigerant flow as the set temperature in each room is achieved then maintains it at that level.

The “heart” of the Multi-split system is the inverter type compressor. This type of compressor automatically regulates its workload according to the needs of each individual unit and the selected room temperature requiring a lower energy demand and less power consumption once the required temperature is reached and maintained.

Why is Multi-Split Air Conditioning important?

A Multi-split system air conditioner is much quieter and responds automatically to applied heat loads such as increased occupant numbers, influx of outside air through opening doors or changing solar characteristics as the sun changes direction.

More consistent comfort levels for all occupants within a given living space.
Ability to independently vary comfort levels in different zones
The inverter type compressor, the critical component in the system, has a high COP (Co-efficient of Operating Performance) enabling maximum cooling until the set temperature in each room is reached, then automatically maintains that temperature thereby, reducing power demand.

How can we help find the
best Multi-Split Air Conditioning System for you?

The most suitable Multi-split system for your use depends on a number of factors including the building function, internal volume, number of doors and windows and the number of anticipated occupants.

We will visit your home, site or work with your architectural team to determine a system best suited to your individual needs. Whether that is for a family residence, or multi‑function building.

At Alliance Climate Control, we can bring together the best Multi-split products available from a wide range of options, able to satisfy any operating characteristic that might exist.

From timed operating sequences that activate the system before you arrive home or sleep functions to shut the system down after retiring each night. Even Wifi activated applications are available to control your Multi-split system with a Smart phone application whilst you are away from home.

We will also be there with you during the installation and commissioning process to make sure the selected unit will deliver the requirements ensuring you are absolutely satisfied before final acceptance.

We will also be there to support operation of your system to make sure it operates correctly day after day, year after year.

Job #100840 Andre was punctual, presented himself well and knowledgeable. He was thorough in his servicing and we're happy with the results.

We recently bought our first home and when our AC started leaking into our ceiling we were so panicked. The Alliance team were so helpful, they got out to us quickly and gave us a very honest assessment. We were lucky enough to have our new AC installation completed by Qais, Cris, Eric and Mike and they were fantastic. They were so professional and super fast, we have been so happy with the service and are so glad we decided to employ Alliance to replace our old unit.

BJ & James did an excellent job installing our new Daikin split system…they were on time, professional and very tidy. Vash & TK did the electrical wiring and were great to deal with too. Aysa did the original quote and was brilliant, great guy and very helpful. Also spoke to Will & Cara in accounts. The Alliance guys are a super team and I would definitely recommend them for all your a/c needs!

The Alliance team at all levels were outstanding in their professionalism, customer survive & attentiveness & pricing – I’d like to name Errol Kaymaz for all his help & professional advice & how he made himself available to me whenever I needed help or had a question at every stage of the process & to the assigned technician, Louis & Gokhan who installed the unit today - Louis & Gokhan were delightful & extremely professional & courteous at every stage of the instillation - I recommend these two technicians get a raise - I’ve never encountered such great tradies & I highly recommend alliance - thank you so much for services & please continue to keep your level of quality & expertise the way it is.

Boys turned up before time explained as they were going and did an excellent job more than the previous company had done Emre and his assistant were great took there time and did the job.Excellent work even though was only a service on two different units

James W.

I’m very impressed with Kody’s professionalism during the air-conditioning diagnostic at my apartment. He thoroughly explored all possible options and was careful not to jump to conclusions, which really demonstrated his patience, expertise, and integrity. It was clear he was focused on finding the right solution rather than being money-oriented.

The team also went above and beyond by waiving the initial call-out fee due to a booking error, which was a very appreciated and thoughtful gesture.

Highly recommend their service. Wishing Kody and the team a Merry Christmas and a Happy New Year!

Geni S.

On time. Detailed report. Polite service. 3rd year annual service. Highly recommend.

I had an excellent experience with Alliance Climate Control installing the air conditioning unit in my shop.
The service was fast, clean, and extremely professional from start to finish.

Yunus, arrived ahead of the shop opening, took the time to understand our needs, and recommended a unit that was perfectly suited to the space. His colleague Gokhan was also incredibly helpful throughout the installation.

Both were polite, discreet, efficient, and worked with great care. They left the place spotless after the job, which I really appreciated.

I highly recommend Yunus ,Gokhan, and Alliance Climate Control and would absolutely use their services again. Outstanding work.

ian L.

The three contractors, Yunus, Can and Veysal were the most pleasant and courteous workers. They spent two days installing my air-conditioning in 40 degree heat in the ceiling and didn't complain. I would highly recommend them.

Sasanka D.

Thank you to the Alliance team for the replacement of my ducted AC . It wasn’t cheap but I was impressed with the long term approach of this company. The team who came out (Andres R/Christian C/Dilan) were fantastic with replacing the ducting putting the new unit in. Andres was so patient in showing my elederly mother how download the Panasonic app and to use the controls etc . Thanks again!

Shin K.

The team Kristin, Aaron P, John M, and Chris D were as good as it gets. From my initial request with Adrian, confirmation appointment with Kristin to the actual work undertaken was all a pleasure. For me as a customer I was again impressed with their expertise and their communication. There's a lot to be said about Alliance, all good!

rada P.

Liam was fantastic. Very friendly, clean and job well done. Highly recommend Alliance. Always such a good service. Have used many times and will continue to. Keely also super friendly and helpful giving me eta so I wasn’t waiting.

Amith S.

The service and follow up was prompt and as promised... We had a 9 year old AC unit which had stopped cooling and making unsteady noises... The initial review and assessment to change the unit foundations which was rotting and a service was point on. The service person was prompt, very kind and mindful despite the difficult access to the roof unit. Have to say, the only issue I'd have was the initial inspector and quote pushing us to replace the unit for double the service price which in itself was a bit pricey, but in these days a full days of work it's expected. All in all an happy customer, as happy to pay a premium for a job well done! Great service - definitely will use again.

Mary

Explanation and co-operation from go to woe. Couldn't be happier 😁
