How Do I Know If I Need

Being able to identify common air conditioner problems is key to ensuring your unit stays in good working order. 

Signs of a broken air conditioner include:

  • Air conditioner running but not cooling 
  • Stuffy feeling or musty air
  • Loud running or strange noises 
  • Air con unit leaking water 
  • Foul smells coming from the system
  • Temperature fluctuations
  • Poor cooling or slow to cool 
  • Visible condensation on walls and windows
  • Excessive electricity bills 

If you’re seeing any of these symptoms, there’s no doubt that something is wrong with your air conditioning unit. This could be caused by many things, but without a professional diagnosis, it can be hard to identify the problem.

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.

When you book an appointment with us, an Alliance technician will visit your Sydney home promptly. 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.

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.

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 😁
Jennifer F.
Replacing old gas heating system with new heating and cooling system. I was impressed with Jake’s knowledge when he came out to quote the job, then the Installation team was very experienced and professional, good communication and provided onsite solution. I am very happy with the result, thanks to Vy, Lyn, Eric & Peter.
Eric T.
We got AC for our North Bondi house and could not be happier.
From initial conversation Aysa came up with a very genius plan for placement installation of the AC. Installation team Gokhan, Louise and Charles was so helpful and made the idea happened
They were so clean, tidy up everything and super knowledgeable. They did a schmick job.
Many thanks guys 🙏🏻
Allan L.
Happy with the work done, clean up and respect for our property by Ivan and his partner (sorry name forgotten). Follow up plaster work was also done well and Liam is to be commended.
Ugur O.
Charles and Arron did a great job installing the pendant and outdoor lights. Took great care to leave everything perfect and clean.
Simon van W.
We installed our air conditioning 5 years ago. The installation was perfect and we have had no issues in all the time we have owned the system. We had to get them back because one unit was leaking water. They were prompt to attend to the problem, admitted that some of the problem was their issue and they would cover the fix themselves.

They owned the problem. They are always very polite. The engineers they send out are highly professional, leave no mess, take off their boots and are good at communication with the client.

I've recommended them to many people..
Tam T.
We have asked Alliance Climate Control to come and service our 2 air con systems (one central and the other, a stand slone unit). Andres - a young trademan came ontime with prior warning and did a really good job for us. We also had Kyle (?) coming later to fix a condensate leakage issue which he also did well, on time with prior phone call. We then signed a 3-year maintenance contrsct with ACC after our good experience with their workers. We strongly recommend this group, having professional and friendly staff working for the company. Thank you ACC
Ian B.
We were delighted with our experience with the Alliance team of Tommy, Nick and Luan. They went about the job professionally, expertly and with no fuss. They left the job site as they found it, perfectly clean. What a wonderful example of hard working young men and a credit to your organisation. All contacts with these young men were courteous and polite. Well done Alliance.
Angus H.
Connor and Steven completed some drainage works and also a service of three of my AC units today. They were friendly, professional and communicated excellently. Highly recommend these guys!
Christopher B.
Alliance team on time and efficient. Thanks Shabi and Louis for handling both the callouts so well.
Elliott Y.
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!
David B.
Very happy with the product and the installation, very professional and efficient. Highly recommend.
Clemence W.
We had Shabi, Louis and Nicolas install our aircon right before the heat wave this week. They worked really hard and we love the result.
Kathryn T.
A big thank you to the whole team for a professional and very clean job, can’t thank them enough. They fixed up our ducted system and installed a new system at the back of our house! Big shout out to Andre G for managing the ducted service, and to Gokhan, Veysel, Michael and the electrician Charles for installing the new system. We will now use them for all our servicing.
Sue H.
We were very impressed with all aspects of the installation and replacement of our outdated ducted air conditioning system. The prompt response we got from Jake, who came out to scope the job & provide a quote was very impressive. As was the turnaround from accepting the quote to the installation (3 days). The team who carried out the installation, were terrific & worked tirelessly to get the job done with minimum disruption, which we appreciated as it was a fairly complicated job. We would like to thank each of them, Jonathan, Miguel, Matt, Maisam & Ahmad, they all deserve a shout out. All in all from start to finish it was a great experience & couldn't recommend Alliance highly enough.
Steven K.
Lachlan was professional,punctual and pleasant to deal with

Job well done, Jason was very clear in the process before hand and also explained everything well when finished.

Update: 3 Dec

Decided to ask ACC to do some straight electrical - powerpoint installs , sconce replacement.

JJ and Aden did a great job: quick, friendly, informative. Really neat job. Cleaned up after themselves and even took the old sconces for disposal.

Happy with the work.

JJ also noticed some switches were out of code in my switchboard and recommended and completed replacements.

So house electrics are a little safer too.

AIR COND INSTALL Review:

Two teams worked on our place:

Andres , Cristian and Qais replaced our ducted system, and Vy, Luan and Maison installed a separate split system where ducted couldn't reach.

Both teams did an excellent job.

Everyone arrived on time, walked us through what was going to be done and were happy to answer any questions. They were friendly and professional. Completed install on time, showed us how the new system worked and made sure we were happy. Cleaned up afterwards too - as promised.

Ducted team worked for two days in some hot conditions, removed old unit and ducting and disposed off. Hassle free for us. Install of new system, ducting and control system was trouble free for us.

Split team did a great job too - gave advice on best position for indoor and outdoor unit, clean efficient install, tidied up after themselves. Really professional.

Great from start to finish.
M E.
Tech was nice polite guy but he did not have the correct filters and wanted to cut some down to fit .. this does not work as cut down filters do not hold their shape so I told the guy not to replace them this time although the cut downs ones that were installed last year were quite clean, they were not in good shape.
Update: the company apologised for not having the correct filters at the time and promptly arranged for the correct units to be installed .. they really do follow up and fix any issue so deserve 5 Stars
Alex K.
Alliance are the best! Garret, Shane and Louis did a fantastic job installing our new AC unit. Protective mats were placed on all floors, they removed all mess and even took away our old unit. Garret ensured we were across the installation process, asked questions when required and also informed us of how to operate the new system. Great job!
Elaine B.
Excellent and professional service from start to finish. Particularly impressed with the team who did the installation. Efficient and careful. Attention to achieving optimum performance from the system much appreciated.
Karen P.
Jake and James were efficient, punctual, clean and courteous. My AC unit is as good as new. I would have no hesitation in recommending Jake and James and I will certainly use Alliance in the future. Thank you guys.
Maria C.
We had our split system air-conditioning installed almost two years ago now (April 2024) and I have been meaning to write a review, because we were really happy with the service and installation, and I have only just got around to it. But that may be good, as I can say that the system works perfectly, and we have had not problems.

We have an inner city terrace, and have over more than a decade got quotes, only to be told that "it is not possible". So, I looked for someone close, who I figured would have experience with our type of dwelling. The quote was very reasonable, the installation went smoothly, and we are very happy.
Tracey H.
Very good service from BJ, James, Errol and Will for our air conditioner installation. Errol and Will were very responsive and flexible during the consultation and booking phases - I felt like their advice was solid and really suited my circumstances. BJ and James were an incredibly professional and efficient installation team - they got it done, cleaned up, and made sure I was across our new aircon. Would recommend.
Kylie B.
Excellent service - on time, friendly and professionally completed the job ( air conditioning & two ceiling fans). Also cleaned up and put furniture back into position.

Thank you to the team who did the work - Shabi, Louis, Peter & JJ.
Also to Will behind the scenes who coordinated the scheduling of this job ( fans added in )
Thanks again
