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.

We’ll let you know exactly what the fault is and the best way to resolve it: whether that’s an air con service, technical repair or part replacement.

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.

Les M.
The two technicians who came to do a major service on our split air conditioner was exceptionally professional thorough and extremely knowledgeable- I recommend this company very highly
Irena L.
Shadi, Ilch and Christian installed my air conditioning system recently and I was very pleased with their professionalism, courtesy and thoughtfulness. They arrived on time and got to work straight away. They contained all the mess and cleaned up before they left. I highly recommend their work.
Roderick W.
Excellent service. The guys helped me learn a few new tricks with my control panel as well. Explained in detail what they were doing and how it works, and after checking the air distribution through the ceiling vents, went back into the roof to tweak it just right.
Karen S.
The customer service was excellent and the installation for my new air conditioner was very professional and prompt..
All of your staff that I encountered through the process were very friendly and knowledgeable.
I would highly recommend your services to my friends and Family.

Liam was punctual, respectful, discussed options. Was tidy and efficient. Have been using Alliance for years and recommend them extremely highly.
Angharad M.
I’m so glad I chose Alliance for my air con. From the consultation to post installation after care, everything has gone perfectly. Alliance has consistently delivered on their promise; they’ve turned up when they said they would, completed the job in the stated time frame and made sure I was happy with the work. The electrons even installed a towel rack for me - because they were there and they could. Nothing is too much trouble for these guys! Fantastic quality job and service.
Kellie S.
From the get go, my experience with Aysa was great. Very patient in answering all my questions through the initial consultation.

Huge thank you to Tommy, Moe, Shaad and Gokhan for their professional work in installing the multi split system air conditioning! They were professional from arrival and took care to carefully prep my place before the job and took a lot of care in cleaning after. They explained everything and made sure I was comfortable with everything.

Definitely recommend Alliance - I will be using them again for future jobs.

Jacinta and Angela O.
Jason and Nic were wonderful. Fixed everything and then some. On time, timely, careful, considerate, polite and tidied up beautifully.

They were also incredibly tolerant of our very noisy dog and his less noisy brother. Will definitely be back if we need anything. Thank you so much.
Debra A.
Just had my initial inspection with a young man called Kyle. He was knowledgeable, polite, informative and friendly. I have locked in a date (of my choosing) for work to be done. I hope the technician who does the work also has the A1 customer service skills of Kyle. The lady i originally made the appointment with also had the A1 customer service skills. So far, so good Alliance - thank you!!!
Jacqui H.
Ivan, Maisam and Mosa did an amazing job installing our new AC system. They showed up on time, they were courteous and clean operators and delivered a very neat finish. They did a really nice job fitting it in around our old terrace and were sympathetic to the outside appearance. The whole experience from initial consultation and sales process with Jake, to installation was seamless. We would highly recommend.
Jason Y.
very impressed with the work of one of Alliance's team, V the team leader and Kim, Eric and electrician Charlie and sales Liam they are good blokes and handled my job with care and confidence, they know what they doing and job delivered seamlessly.
I found this company very organized with their structure and definitely recommend to anyone who has needs for it.

Loannis and Liam did a great job with patching up the hole that the team the day before left after installing my new AC. The team overall were a pleasure to work with. Will definitely use their services again.
Paul S.
Second time I've used these guys.
It's the second time they've been prompt, friendly and have done a terrific job. Great service.
Susie Z.
I recently used Alliance Climate Control to replace an old, broken air conditioner with a new ducted system. While their quote was higher than others I received, the level of professionalism and the final result made it worth every cent.
Our home has a very narrow roof space and significant temperature imbalances between rooms. Most companies simply told me what I wanted was unachievable. Jake, however, took a different approach. He was incredibly thorough—measuring everything and being completely upfront about the challenges. He walked me through several scenarios of what might happen once the roof was opened, giving me total confidence in their expertise.
The installation team, Yunus and his crew(Brody, Can and plasterer Liam) were professional, courteous, and went out of their way to accommodate my requests—including moving the outdoor units to a new location at no extra charge. Yunus made sure that each detail was perfectly executed.
The outcome is way better than our old system; thanks to Yunus, the new ducts are much better placed and the zoning works perfectly. The results actually exceeded my expectations.
I highly recommend Alliance Climate Control for anyone who wants peace of mind and a team that is willing to tackle difficult problems with honesty and skill.
Teresa W.
Excellent and attentive service. The team were professional and took care in ensuring everything was working and tidied up before they left. They showed a great deal of patience in getting the app working on our mobile phones. We are happy with our new reverse cycle air conditioners and happy to very highly recommend them.
William van L.
Gave our AC a tune up, pricing was moderate to high, but the job was done well. They were also able to quote up and carry out extra electrical work.
Peter B.
Routine service of a/c units. Alliance Climate Control had initially provided a 3 hour time window; Jason texted a 1/2hour prior to arrival and he & Nicholas were on time. They were attentive in listening to and understand my initial concerns. They were efficient and tidy in their work and then explained clearly what they had done. Overall excellent service. Barry
Jill
The technician was on time, professional and competent. We were completely satisfied with the maintenance service,
Tracy H.
Thanks Dylan great job!
Sophie G.
Fast response time, lovely people, respectful and hardworking techs. No complaints, highly recommend.
Biljana R.
I received outstanding service from Jake, Ahmad, Louis, Callum Yas and Loannis. Highly professional, reliable and effective service from the inital quote to installation and then follow-up. Alliance was my highest quote but so worth every cent which speaks volumes about the peoduct and service I received. Absolute value for money. They went above and beyond to make me feel satisfied. If you want high quality... choose these guys... you will not regret it. A ten star rating from me!
