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.

Is Saying About Alliance
EXCELLENT Based on 2550 reviews Posted on Tess G26 February 2026Trustindex verifies that the original source of the review is Google. Mohamed and Ryan of Alliance Climate Control took care of the electrical needs of the installation and they were very efficient and worked well. They communicated with us and instructed us with a detailed summary of what they did and provided us with contact details. Very happy with how they just got on with the job.Posted on lucy conway26 February 2026Trustindex verifies that the original source of the review is Google. Fantastic service. We had a bit of a difficult job and they came in with ease, no issues, job done. Very pleased !Posted on Helen McFarlane26 February 2026Trustindex verifies that the original source of the review is Google. Split system air conditioning installed by Alliance. Great non-intrusive design initiated by installers. Ie, the cabling was put under the upper floor and then into an existing air vent, then out under the eaves and down behind existing drain pipe, causing minimal visual impact. Plasterer work and electrical work also excellent. (Painting to be done by owner. My choice.) Very happy with the outcome and the service provided by Vy, Eric, Meddy, Harry, and JJ. Job no. 99701.Posted on Rob McInnes26 February 2026Trustindex verifies that the original source of the review is Google. Great service at a predictable firm cost. Friendly staff, everything explained well, and best of all the guys kept the job clean while working around a house of busy home office workers. Bonus points for making sure the dog didn't escape (and giving him pats). Thank you and we'll be back.Posted on Penny Hodges25 February 2026Trustindex verifies that the original source of the review is Google. Very happy with Alliance. Thorough, professional and reliable. The electrician who came to my home was a great problem solver tooPosted on Dianne Coughlan25 February 2026Trustindex verifies that the original source of the review is Google. Extremely happy with the light and switch installation. Good clean up and return of furniture that was moved to correctly position the installation. Many thanks to Mohamad and Ryan. Keep up the fantastic work.Posted on Oz Butterfly25 February 2026Trustindex verifies that the original source of the review is Google. It was a complex installation - a multi split system - in a small strata unit too high up for ladder work. Liam, BJ, Theo, Aaron & Ken made it fit together & the installation on the day was challenging, but hassle free. Everything cleared away and back in its place at the end of the long day.Kathrine & Luka in the office made the set up easy.Posted on Dimitri Efthimiopoulos24 February 2026Trustindex verifies that the original source of the review is Google. Excellent service, technicians appointed were superb very polite and respectfull during their visit at our premises. They were excellent pointing out the incorrcect filter mesh was used on initial installation allowing a considerable amount of dust passing through the return air grill and highly suggested we replace this with a more appropriate filter media. Left us a diagnostics sheet showing all checks complete which was also a positive.
