Common Reasons for
Air Conditioner Repairs
Modern air conditioners are built to last, even when dealing with Sydney’s climate extremes. However, like all machinery, there are times when things go wrong and your air conditioning unit may need to be repaired.
Some of the most common causes of air con repairs are:
- Fan coil, fan or filter blockage leading to poor cooling
- Water leak because of blocked or damaged drain
- Failing or inefficient outside condenser unit
- Temperature and humidity sensors are faulty
- Refrigerant gas leak causing critically low levels
- Swing motor or air vents not working properly
Here at Alliance Climate Control, we are familiar with the roots of common air conditioner repair needs. This means our technicians can diagnose faults quickly, find the right solution, and get your air con running smoothly again. We will also give you an understanding of how the fault occurred and how to avoid it in the future.

Air Conditioner Gas Refills
An air conditioner gas leak is one of the only times your system will need a gas refill. In fact, it’s illegal to perform unnecessary gas refills in Australia. If a gas leak is detected and repaired, it’s standard for the technician to refill the refrigerant gas as part of the process.
If your air conditioner is repaired by an amateur technician, or one not licensed to handle refrigerant gas, this can cause permanent damage to your air conditioning unit.
Here at Alliance Climate Control, every member of our team is licensed to handle refrigerant gas. When you know that when you book a repair with us, your system will be handled by trained professionals from start to finish.

Air Conditioning Compressor Repairs
The air conditioning compressor is a major component in the air conditioning system. A faulty air conditioning compressor will not only affect the performance of the air conditioner, but can also cause damage to the rest of the system.
Signs of a broken air compressor in your AC unit include:
- Loud sounds, such as screeching or metallic noises
- Poor air flow or cooling performance
- Circuit breaker tripping repeatedly
- Air conditioner doesn’t start properly
Alliance Climate Control technicians are trained and equipped to repair all brands of air conditioning compressors. As one of the hardest working components of your air con unit, air compressors generally need repairs for either impact damage or long-term wear and tear.
Our technicians provide repairs and replacements for a range of different types of air compressors, including split system and ducted air con compressors. To book a repair appointment, give Alliance Climate Control a call.

What Our Community
Is Saying About Alliance
The service technician arrived on time. He was courteous, pleasant, competent, did a thorough job, carried out the work competently, was very organised, worked safely and maintained a clean worksite both inside and outside the property.
A pleasure to have this quality of service!!!
B.J,Theo and James installed units in 2 bedrooms upstairs and an inverter outside. They did a great job and had it done in one day.
We also had 2 other unots serviced and cleaned by TK and Eric who were thorough and gave us maintenance tips. The quote from Kody was spot-on and heaps betyer than the main competitor.
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.
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!
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.
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.
Turned up on time, knowledgeable technicians.
All very tidy too, with everything, even the old fans taken away - great work, thanks Charles and team!
Good humoured in spite of having to climb stairs because of broken lift.
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.
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.
We would highly recommended Alliance Climate Control for their high quality work.
