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

  • 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. At every stage, we keep you in the loop about what’s going on and the costs to expect.

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.

HIGHLY RECOMMEND FOR ALL YOUR ELECTRICAL NEEDS. Tops! Very Professional! Very Friendly! Since installation my AirCon System, I have used them with all my electrical needs. Easy to deal with. From the Reception to Trade Guys who will perform the job, easy to talk to. If your call was not answered the first time, there is always someone who will ring and follow up the call. Very responsive! It was late at night and pouring rain then, when leaks occurred in our roofings because of the newly installed aircon. On my call for service, someone came immediately to fix the roof leaks even though it was very late at night and raining. No second thought. THAT’s WHAT I CALL SERVICE! This company installed my aircon system, replaced all my down lights, and front & back sensors. I use them all the time. Trade Guys are so friendly, easy to talk to, very professional in what they do. Two thumbs up! Erlinda from Castle Hill

Masa and team installed a split system aircon for me in the studio over the garage. It wasn’t the easiest install with external unit installed on a very high second story roof and getting power to it proved challenging but Masa did a great job and even cleaned out my gutter while he was up there !

The guys who installed our new Dakin really went above and beyond our expectations. It was an unusually tricky job which was executed brilliantly. They also vacuumed up afterwards. Generally great ambassadors for their company! Well done and Thankyou 😊 I have just used Alliance Climate control again for another project. Ivan and his team did an exceptional job. I can highly recommend them. They also left the job spotless. Thank you

We had our old Daikin air con replaced by Yunus, Can, Veysel and Brody. These guys were fantastic. Arrive on time and from that first meet have been great to deal with. Very professional and polite. Throughout the process Yunus explained to me what they will be doing and kept me updated. Their workmanship has been great and have laid drop mats to protect the flooring and cleaned up after themselves. Overall awesome work and a very happy and satisfied customer. Well done to Yunus and his team

I’m very impressed with Kody’s professionalism during the air-conditioning diagnostic at my apartment. He thoroughly explored all possible options and was careful not to jump to conclusions, which really demonstrated his patience, expertise, and integrity. It was clear he was focused on finding the right solution rather than being money-oriented. The team also went above and beyond by waiving the initial call-out fee due to a booking error, which was a very appreciated and thoughtful gesture. Highly recommend their service. Wishing Kody and the team a Merry Christmas and a Happy New Year! **Adding on post 1st visit** Following my initial review, I had to call Kody back as my aircon started leaking after the first visit. We discussed a repair that might involve cutting into the gyprock to resolve the issue. On the day, Dylan, Colin and Ioannis attended and were extremely professional and accommodating. Instead of immediately cutting the gyprock, they took the time to explore alternative solutions and managed to fix the issue without opening up the ceiling, which I really appreciated. Big shout out to Ioannis as well for offering to patch up some paint on the ceiling free of charge - a very thoughtful gesture. Really impressed with the team’s creativity, professionalism, and willingness to go the extra mile. Highly recommend them. *Adding new review 2026* Charlie, Aaron and Sean has been nothing but professionalism from start to finish. Thanks for your help in squeezing in the last-minute appointment and tackle the unexpected hurdles during your visits. I really appreciate your friendliness, professionalism and workmanship. Cheers guys!

All around excellent experience - from Aysa who stopped by a few days ago and discussed the options I had (to replace an AC unit in my apartment) to the installation of same, within a week, by Gokhan and Meedy. Hard-working and diligent fellows all the way to the disposal of the old unit and the clean-up. That company is well-run! Recommended.

Your installation has been mostly excellent but very recently I noticed that the condensation has not been flowing into the evaporation tray. There is a short horizontal section of the pipe for discharging the water into the tray but the water, instead of dripping into the tray, tracks backwards and drips onto the floor. I have remedied this by attaching a plastic cone to that short horizontal section. In the future, ensure that the last short section of the pipe SLOPES into the tray to ensure that water doesn't track backwards.
