  • 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.

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.

Very happy with the experience - booking/communication/time of arrival and upfront quotes all good. Emre was knowledgeable and a tidy worker. I had two ducted aircon units serviced and some other work to correct previous incorrect installation. So much better now!

I had my ducted and split aircon systems serviced by Connor, who was courteous, considerate, and thorough in his work. Alliance’s service fees are on the higher side, but their service quality and diligence is a cut above the rest.

Update: I cannot recommend the team from Alliance Climate Control highly enough. JJ attended to provide the quote and was professional, knowledgeable and took the time to understand exactly what I was hoping to achieve. Charles and Sean carried out the installation, adding new power points throughout my old Federation home. They were incredibly professional, courteous and accommodating from start to finish. Every request was met with a positive attitude, and they consistently went above and beyond to make sure everything was exactly where I wanted it. The quality of their workmanship is outstanding. They took great care while working in the house, treated my home with respect, and left every room spotless when they finished. You genuinely wouldn't have known they had been there, apart from the perfectly installed electrical work. It is becoming increasingly rare to come across tradespeople who combine such a high standard of workmanship with exceptional customer service. JJ, Charles and Sean are an absolute credit to the company. If you're looking for electricians who are skilled, reliable, respectful and genuinely care about doing the job properly, I would not hesitate to recommend them. I have also used Alliance Climate Control for my air conditioning installation and ongoing servicing, and I have consistently received the same exceptional level of customer service and workmanship. It's clear that this standard of excellence is part of the company's culture. Alliance Climate Control is truly outstanding. Thank you all for such a fantastic experience. 2 years ago: I had an excellent experience with Alliance Climate Control, thanks to their outstanding service technician, Kyle. He was incredibly professional, explained everything he was doing in a clear and detailed manner, and performed the service with great care and expertise. It’s rare to find such high-quality service these days, and I truly appreciate the effort he put in to ensure my air conditioning units were in top shape. I highly recommend Alliance Climate Control for all air conditioning needs.

Another wonderful experience with Alliance. This is the second home I’ve had split system air conditioning installed with Alliance and once again they’ve performed superbly. The quote provided was detailed and professional and the installation was seamless. Yunus and his off-sider did the installation for me on this occasion. They were professional, respectful and very hardworking. With Alliance, you get what you pay for -high-end, skilful service and delivery.

Highly recommend Alliance Climate Control. They did a fantastic job on my air conditioning system from start to finish. The team was patient, professional, and took the time to explain everything clearly. They also went above and beyond by carefully protecting my furniture during the work and keeping the common areas clean and tidy throughout the installation. It's clear they take pride in both the quality of their workmanship and respecting their customers' homes. Great service, reasonable pricing, and an excellent overall experience. Thank you

Today, I replaced my ducted air conditioning system, provided by Alliance Climate Control company and I would like to state how happy I am with the job and installation staff and also the rep that had come to quote me. The installation staff, Garrett, Richard, Eric, Matt and Harry were very professional and courteous. Alex, the company rep, was also very professional. Before, during and at the end of the installation was seemless and I wholeheartedly recommend Alliance Climate Control to anyone that needs a good job done. They even vacuumed the floors afterwsrds and took the old system away. Rarely have I seen such good service from any company I have used over the last 10 years. Well done Alliance and staff.
