What is VRV Air Conditioning
System Service and Repairs?

Regular service and repairs of a VRV (or VRF) air conditioning systems are critical to make sure your system continues to maintain its designed operating efficiency.

Regular inspections and checks on operating performance can be completed by our technicians with ease and without compromising the operation of the system or inconveniencing those in the conditioned space.

Such inspections are an invaluable tool for trouble free operation and should be performed on a regular basis. A regular service and maintenance inspection will keep your system in optimum operating condition and may prevent unplanned equipment downtime and costly repairs.

Why are VRV Air Conditioning System Service and Repairs necessary?

VRV air conditioning service and repairs when scheduled regularly, make sure your system is working at peak performance, ensuring filtration mediums are free from dust or pollens that may result in unpleasant odours or adversely affect the health conditions of occupants.

Incorrect operation of the digital expansion valve thus providing an inconsistent flow of refrigerant resulting in occupant discomfort.
Build-up of dust or pollens in the fan, coil or filters within the indoor unit or poor sealing at room entry grilles allowing ingress of dust or conditioned air to escape.
Low level of refrigerant gas. This may be perceived by occupants as inferior cooling efficiency and result in selection of a lower temperature in turn causing compressor overload.
Dust accumulation on fans or condenser coils, reducing the heat dissipation characteristics of the condenser system.
Inaccurate load sensing of the compressor causing inefficient circulation of refrigerant gas.

How can we help with inspection and repair of your
VRV Air Conditioning System?

Alliance Climate Control can help to make sure your VRV air conditioner system continues to operate with optimum efficiency.

At regularly scheduled services, we can check the operation of the indoor unit and room entry grilles to make sure all components are sealed properly and working within their optimum range.

We can also check the system pressure at various points within the circuit to verify optimal performance of the compressor and thermal expansion valve.

Additionally, we can also check the outlet temperature against calibrated thermometers to ensure the desired air temperature is being delivered.

All these checks completed on an annual basis will ensure your system is always operating at optimum efficiency providing maximum comfort.

Gokhan, Can and Niko have installed our new AC and removed the old one. Professional, kind, polite and very respectful. They cleaned all rubbish and packing materials from the works. They left the area clean and all the works have been done with good workmanship. Very careful with our belongings. Happy with the installation. Electrical works are still ongoing.

Edit to add the electrical installation- Mohamed and James were amazing. The job was very long, but the persevered and did a very nice neat conduit. They cleaned up after drilling and the cut offs- very neat work and great quality. Very polite and professional.
AC works ! Thank you for your services, would not hesitate to use ACC crews again.

Brent H.

We had an AC unit installed by another company over a year ago and it’s sadly had several issues. Kody MB from Alliance was an absolute life saver in getting us sorted out and further helped us in setting up a future appointment for maintenance.

I can’t stress enough how helpful, kind and professional Kody was. I would highly recommend Alliance, and Kody, for any AC jobs you might be considering.

Back in mid December 2025, the guys from ACC installed our air con and did a fantastic job. Liam was consultative throughout the quoting process. And thanks to Jono, Ben, Charles, and Aaron, the final installation of the indoor and outdoor units, as well as electrical work was delivered to a high standard of workmanship. They left everything clean and tidy, and we're very happy with their work.

It also doesn't hurt that they were friendly! Bonus points for being unfazed by our vocal little dog! Thanks guys!

Ivan, Mosa & Luke and electrician Aaron, Ken & Harry were very professional and courteous while they installed my ducted system in my upstairs bedrooms on a very hot day (34 Degrees).
They were on time, worked well together and non-stop to complete the job in 1 day.

recommend their service.

Totally impressed by Alliance. The communication was very good and the technician (Kody) was personable, professional and most helpful. Kody presented options to resolve our ac problem and was honest and objective with the choices before us. The repair was completed on the initial visit! Particularly good value. A very happy customer and we’ll definitely call them if we have any future ac needs.

Re: Dais, Sayed & Christian
Hello,
I have been meaning to send this email for quite some time, but due to poor health, and lots of other excuses, I simply haven't gotten around to it.

I wanted to provide feedback for the above job number, as the boys really did work their arses off! It was a complicated job (which even I could see as a layman), and yet nothing was off-limits. They really did everything to accommodate the job, and my individual requests. As an individual, I am very particular and hold very high standards, and yet, they did not blink and eyelid.

I would also like to mention that all three of them were a delight to have in my home. It goes without saying, that they are a credit to your company, and it was an absolute pleasure working with them.
Kind regards
Lisa

Noah B.

Alliance installed another Daikin Zena split system in our house today and did a brilliant job as per usual. Ahmad & Maisam were the install team and they were fantastic…explained things perfectly and did an absolutely first rate job. Very happy. Also want to mention Sam from the installation team who helped me with a last minute change the day before the job…he was a massive help! Great people and wouldn’t hesitate to use them again
