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. 

That’s why the team at Alliance Climate Control is always ready to troubleshoot your air conditioning issues. When you book an appointment with Alliance, one of our Sydney technicians will visit your home for an expert inspection and diagnosis of your air con system. 

Air conditioner repairs can snowball into much more expensive issues if left too long. If your air con is having issues, it’s best to call a reliable air conditioning service right away.

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.

We couldn’t be happier with the outstanding service from Alliance Climate Control! The team delivered a truly seamless installation of four split systems at our home (Service Ref. #101598) from start to finish.

A special commendation goes to Ahmad Maisam and Meedy for their exceptional leadership, organisation, and genuine care in addressing our needs. Their professionalism, clear communication, and attention to detail made the entire process smooth and stress-free.

The workmanship was excellent, the team was punctual and respectful of our home, and everything was left spotless at the end. Simply put—the best team ever. Highly recommended to anyone looking for top-tier air conditioning service!

Laura
The team who attended my home last week to install a split system were impeccable - Gokhan, Louis and Rodrigo - as was Errol who attended to provide the initial quote and the office team when I called with some questions pre-installation. Everyone was helpful and professional. They set high expectations and delivered!
Christian B.
Andres from Alliance was excellent, professional and very clear. Our units are now operating perfectly and he detected a major issue and presented multiple solutions. Would recommend the service highly.
Sky S.
I couldn't be happier with the excellent service and clean provided by Emre.
He was punctual, thorough with his assessment of my aircon units and managed to identify the source of why my aircon has a mouldy smell. He was professional, knowledgeable and clear with his explanation of what can be the problems as well as recommending appropriate options to address the problems.
5/5 will call upon his services again if my aircons ever give me grief (though I doubt it with the level of servicing he performed).
