How Do I Know If I Need
Air Conditioning Repairs?

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.

Gokhan, Can and Niko have installed our new AC and removed the old one. Professional, kind, polite and very respectful. They cleaned all rubbish and packing materials from the works. They left the area clean and all the works have been done with good workmanship. Very careful with our belongings. Happy with the installation. Electrical works are still ongoing.

Edit to add the electrical installation- Mohamed and James were amazing. The job was very long, but the persevered and did a very nice neat conduit. They cleaned up after drilling and the cut offs- very neat work and great quality. Very polite and professional.

We had an AC unit installed by another company over a year ago and it’s sadly had several issues. Kody MB from Alliance was an absolute life saver in getting us sorted out and further helped us in setting up a future appointment for maintenance.

I can’t stress enough how helpful, kind and professional Kody was. I would highly recommend Alliance, and Kody, for any AC jobs you might be considering.

Back in mid December 2025, the guys from ACC installed our air con and did a fantastic job. Liam was consultative throughout the quoting process. And thanks to Jono, Ben, Charles, and Aaron, the final installation of the indoor and outdoor units, as well as electrical work was delivered to a high standard of workmanship. They left everything clean and tidy, and we're very happy with their work.

It also doesn't hurt that they were friendly! Bonus points for being unfazed by our vocal little dog! Thanks guys!

Re: Dais, Sayed & Christian
Hello,
I have been meaning to send this email for quite some time, but due to poor health, and lots of other excuses, I simply haven't gotten around to it.

I wanted to provide feedback for the above job number, as the boys really did work their arses off! It was a complicated job (which even I could see as a layman), and yet nothing was off-limits. They really did everything to accommodate the job, and my individual requests. As an individual, I am very particular and hold very high standards, and yet, they did not blink and eyelid.

I would also like to mention that all three of them were a delight to have in my home. It goes without saying, that they are a credit to your company, and it was an absolute pleasure working with them.
Kind regards
Lisa
Noah B.
