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.

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.

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.

Nelson De A.
Great job . They were punctual, respectful, clean and would highly recommend.
Ranjan P.
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
Ben C.
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!
Rabiye
Great experience from booking to technician completing the service. Friendly, informative and honest service! Thank you!
Billy O.
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!
Xeroeffect
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!
Biljana R.
I received outstanding service from Jake, Ahmad, Louis and Callum. 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. Absolute value for money. They went above and beyond to make me feel satisfied. If you want quality... choose these guys. A ten star rating from me!
Ruairí
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.
Michaela W.
Yunus and his team were brilliant. Courteous, communicative and respectful. I highly recommend Alliance
daniel T.
The technician was courteous punctual and efficient. He was a good communicator and thorough. It went very smoothly. Thankyou
Janice J.
Stayed in contact all the way. Quick friendly service. Everything done on time.
Antony R.
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
Wonderful experience with Alliance for the annual air conditioning maintenance check - very responsive and easy to book, and Kody, the technician, was very polite, knowledgeable and did a fantastic job
Toni H.
Luke kindly phoned to tell me he was on his way. He arrived within the given time. He was courteous, friendly and efficient.

Greg & E.
The maintenance booking and reminder process was easy and excellent.
The service technician arrived on time. He was courteous, pleasant, competent, did a thorough job, carried out the work competently, was very organised, worked safely and maintained a clean worksite both inside and outside the property.
A pleasure to have this quality of service!!!
John L.
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.
We also had 2 other unots serviced and cleaned by TK and Eric who were thorough and gave us maintenance tips. The quote from Kody was spot-on and heaps betyer than the main competitor.
Jack H.
Two great men, well organised, tidy and job well done

Original Review:
I had a split air con unit installed in my apartment by Alliance last week. Yunun and his team did a fantastic job from start to finish. They were friendly, professional and ensured that the unit, compressor, cabling and ducting was installed neatly and blended in with the surroundings. They left my apartment in showroom condition after they finished! I couldn't be happier. Highly recommended.

Update – April 2026:
Andre G came out to complete the annual maintenance on my aircon under job #105771, which Alliance installed last year. The unit was particularly dusty inside, and Andre carried out a thorough service and deep clean. He was professional, meticulous, and explained each step clearly in advance. He did a terrific job and left the apartment spotlessly clean. Thanks again to the Alliance team for consistently great service.
Nina F.
The technicians were on time and professional, they did a really good job deep cleaning our AC units which were very dirty and blocked by molds causing water dripping. I am happy that my ACs was fixed and working well now.
Jacinda M.
2026 - Kyle and Nikola came for my yearly service. They were a pleasure to have. Very professional and did such a good job! I wish I could give them 20/10 stars

Great experience! All the staff are extremely professional. It’s obvious the company has invested a lot into tech and their process to give a great customer experience. Special mention to Gabriel, BJ and Zac for their help!
JJ F.
Very good experience with Alliance Climate Control.

Ivan led the team with Mosa, Zac and electrician Mohamed. Two split units installed and condenser placed neatly at the back.

Process was smooth from start to finish. Clear quote, easy scheduling, no surprises. They arrived at 7:15am and finished by 3pm.

Old heritage terrace, not an easy job. They adapted on site and improved a couple of original decisions. Final result is better because of that.

Workmanship is clean. Conduits through the roof cavity are tidy, indoor units fit well above the windows, and the outdoor unit is discreet.

Ivan communicated clearly throughout and set everything up on our phones at the end.

Professional team. Good execution. Would highly recommend.
stefan W.
Alliance is an amazing company. I thought professional service like this had disappeared years ago. Not only that - but all team members really know their stuff. From the initial sales call with James to comms with the office, booking the day doing the install and cleaning up afterwards everything went like a training movie. How do you get everyone on the same page??? All I can say guys is thank you for an outstanding job - I'd hate to be your opposition.
Joey L.
I had the team from Alliance (Aysa, Vi, Nikola, Eric, Harry, Aiden and James) put in aircon at my apartment. The whole process was great from start to finish. They were professional, punctual, tidy and very friendly. Highly recommend!
Lachlan
The team at Alliance is excellent.

Their knowledge and service lead to an install that was a day shorter and significantly cheaper than quoted. This was completely unexpected after another local company couldn't be bothered to tell me my project was beyond their skill level and ghosted me without providing a quote.

Jason was able to avoid cutting into our ceiling which was amazing after preparing ourselves for a significant patch and paint job.

They are professional, fast and everyone I had contact with was eager to help.

If anyone even slightly mentions air con or an aircon issue I'll be recommending Alliance.
David H.
Alliance Climate Control were a pleasure to deal with. Really professional & a smooth experience from start to finish. I was really happy with the installation team - Qais, Louis & Callum did a fantastic, neat job & left the place immaculate. I asked for a minor change to the drain lines and they were very accommodating.
Stephen K.
Excellent professional service.
Turned up on time, knowledgeable technicians.
Lily L.
We recently had a new ducted air conditioning system installed by Alliance Climate Control and couldn’t be happier with the experience. Liam was the first to attend our home when our 20-year-old system failed. He took the time to thoroughly assess the situation, explain our options clearly, and provide a very competitive quote. His friendly and professional approach made the whole process easy and stress-free from the start. On installation day, Vy and his team were great. They were punctual, efficient, and kept us informed throughout the entire process. They took care to keep our home clean and made sure everything was working perfectly before they left. Overall, the service was outstanding from start to finish. We really appreciated the professionalism, clear communication, and attention to detail. Highly recommend Alliance Climate Control to anyone looking for a reliable and high-quality air conditioning installation.
