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.

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.

  • Loud sounds, such as screeching or metallic noises
  • Poor air flow or cooling performance
  • Circuit breaker tripping repeatedly 
  • Air conditioner doesn’t start properly

Susie Z.
I recently used Alliance Climate Control to replace an old, broken air conditioner with a new ducted system. While their quote was higher than others I received, the level of professionalism and the final result made it worth every cent.
Our home has a very narrow roof space and significant temperature imbalances between rooms. Most companies simply told me what I wanted was unachievable. Jake, however, took a different approach. He was incredibly thorough—measuring everything and being completely upfront about the challenges. He walked me through several scenarios of what might happen once the roof was opened, giving me total confidence in their expertise.
The installation team, Yunus and his crew(Brody and Can) were professional, courteous, and went out of their way to accommodate my requests—including moving the outdoor units to a new location at no extra charge. Yunus made sure that each detail was perfectly executed.
The outcome is way better than our old system; thanks to Yunus, the new ducts are much better placed and the zoning works perfectly. The results actually exceeded my expectations.
I highly recommend Alliance Climate Control for anyone who wants peace of mind and a team that is willing to tackle difficult problems with honesty and skill.
Peter B.
Routine service of a/c units. Alliance Climate Control had initially provided a 3 hour time window; Jason texted a 1/2hour prior to arrival and he & Nicholas were on time. They were attentive in listening to and understand my initial concerns. They were efficient and tidy in their work and then explained clearly what they had done. Overall excellent service. Barry

Biljana R.
I received outstanding service from Jake, Ahmad, Louis, Callum Yas and Loannis. Highly professional, reliable and effective service from the inital quote to installation and then follow-up. Alliance was my highest quote but so worth every cent which speaks volumes about the peoduct and service I received. Absolute value for money. They went above and beyond to make me feel satisfied. If you want high quality... choose these guys... you will not regret it. A ten star rating from me!

Kody was great explained everything that was going to occur. No hidden extras. Great communication and service
Deborah C.
10/10 customer experience and absolutely would recommend. Best tradies we've ever come across! Jason, Nick, Alex, Kyle were awesome and highly competent. After a lot of stress with 2 other aircon companies unable to solve our sensor and filter issues, Alliance came in and did an amazing job. Special shout out to Alex for diagnosing the problem so quickly, and to Jason for going above and beyond to fix it. Will be using them for the rest of our lives!
Paul T.
Matt, Carlos and Meedy installed the replacement ducted air con system at my home in Mona Vale. They went about it quietly, professionally and very respectfully. No dramas. Always available to answer my questions and consulted with me when decisions needed to be made. There was no fuss, just steady progress and completion on time. Exactly what I wanted.

Exceptional team led by Andre with support from Zac and Loannis. Amazing professionalism and workmanship. I will be using this team in the near future for installation s.
Richard Paul M.
A. The ease speed and efficiency of organising a quotation prior to the busy Easter period was trouble free. Harry was articulate, polite, well versed and importantly, punctual.

B. The installation of the two air-conditioners replacing a dilapidated existent set up, was always going to be a challenge and indeed a potential nightmare.

Despite this the team of BJ, Theo and Juan were professionals in the true sense, exhibiting superb communication skills, order and cleanliness from the word go.

The team’s combined technical attributes, attention to detail, ability to work in harmony and answering questions Informatively and logically, is something rare in this day and age.

C. During the entire process, from the initial phone call to the final payment, both Luka and Eric back in the office displayed unrivalled efficiency and precision. There was never any confusion.

In summation, I regard the entire team at Alliance Climate Control with the highest regard and take my head off to the crew. Many many thanks.
🙏🏼🙏🏼🙏🏼🙏🏼🙏🏼🙏🏼🙏🏼🙏🏼🙏🏼

They did a great job, minimal inconvenience and everything was left clean and tidy, would highly recommend them

Fantastic experience with Alliance Climate Control from start to finish. Harry did a great job with the initial quote, and the install team of Meedy, Kim and Ned were professional, efficient and left everything spotless. Couldn't be happier, highly recommend!

Andre the giant and Juan did an amazing job. Made the most of a tricky installation and the finished job looks amazing. Part of the sales pitch of why Alliance was the installation and service quality and this was 100% delivered on. Highly recommend!

I recently had my air conditioning installed and I’m extremely impressed with the whole experience. The sales team- Jake, Eric and Will were professional, clear with their communication and made the entire process easy from start to finish.

I met the installation team on the day- B.J, Theo and Carlos and they were outstanding. Their workmanship was precise, they were polite and respectful in my home, and they took the time to explain everything about the unit and how it works. You can tell they take pride in what they do.

Overall, the service, professionalism, and product quality were top-notch. Highly recommend this company. Thanks again to the whole team! Thanks for being so patient and caring with the old fella B.J., Theo & Carlos!

Used Alliance climate control and electric services for 5 years now and the level of customer care has never been anything less than 100%. Every visit for service or installation is the same standard - extremely professional staff, always on time, always leave the place spotless, and never any need for call back. Wouldn’t use any other company for my air conditioning or electrical needs.

I was so impressed with Alliance after my air conditioner installation I got them back to do some electrical work. Mohamad and TK did an amazing job installing a couple of ceiling fans and replacing three ceiling light fittings. They were prompt and professional and even took away all the rubbish! I'll definitely be using Alliance again. Cheers.

Ivan, Ben, and Can did a terrific job installing my air conditioner into an apartment where little thought had been given by the architect to where the conduit for an air conditioner might be installed. I was very impressed by their perseverance and professionalism. Many thanks!
Maryia

We had 2 teams at our house.
B.J,Theo and James installed units in 2 bedrooms upstairs and an inverter outside. They did a great job and had it done in one day.
