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

- Refrigerant gas leak causing critically low levels
- Swing motor or air vents not working properly

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.

What Our Community
Is Saying About Alliance
EXCELLENT Based on 2037 reviews Linden Davidson28 March 2025Trustindex verifies that the original source of the review is Google. The team at Alliance were incredible - professional, helpful and knowledgeable in all aspects of the job. From quote to service on site, the Alliance team made us feel as though we were the most important people in their business. There was no pressure to buy - they simply presented us with options that were both cost effective and were tailored to meet the unique needs of our property. The instal team - Yunus, Gothan and Emie- were incredible. They protected our space with considerable care and did an amazing job - even ensuring our pets were comfortable and not disturbed by the noise of instal, dust or their work. Yunus led his team well and was extremely knowledgeable- happy to share that knowledge with us to ensure we made the most of the air con unit they installed. To be honest the air con unit became less the focus of our experience with Alliance - really my rating is for the Alliance team and their amazing attention to first rate service and focus on the customer as an individual. Did we get a good product and value for money - yes, definitely. But it is the total experience of working with the Alliance team that we will remember and tell others about. Hence this rather long google review. Every word is true. They’re great. LuLu S28 March 2025Trustindex verifies that the original source of the review is Google. Alliance were recommended to us by friends. James, the sales guy, came out and gave us a few options for our a/c installation. I never, at any point, felt pressured to use their company but I'm glad I did. We chose a multi head Panasonic which suited our house restrictions. You can control it using the normal remote or an App. Which is good for when your kid forgets to turn it off and you aren't home! The communication was excellent with Alliance every step of the way (sales, accounts, schedulers, installers, electricians etc) and we were very happy with the final installation by Yunus, Gokhan, Dragan and Thomas. Everyone was polite, neat and seemed to know what they were doing. Alliance were able to the whole job, including electrical work. Very convenient and recommended. Thanks. Kim Hartill-Law28 March 2025Trustindex verifies that the original source of the review is Google. I was very happy with very professional work done in installing my aircon units . Very clean & careful with my furniture &unit.The whole crew were good Yumus, Gokhon,Emre plus the units are a lot quieter then expected & I love that they match the outside with colour bond cover over the the pipe. They had all the diagrams & certificates for strata & also electricians. So have no trouble recommending this company. indra alexander28 March 2025Trustindex verifies that the original source of the review is Google.

We had our air con installed. From initial consultation to final installation took less than 2 weeks. Jake, Yunus, Gotham, Emre and their team has been exceptionally great. The sales consultation was thorough and easily understood. Jake was personable, personable and communicative. Yunus's installation team was prompt, and engaging. The installation took no time at all and best of all, the place was cleaned up and spotless by the time they are done. The air con is working fantastically. I'm super grateful. Would definitely recommend them and use them again in the future Cosmas Kapsanis26 March 2025Trustindex verifies that the original source of the review is Google.
