Why is Air Conditioning Servicing
Necessary?

Regular maintenance of your home air conditioning or HVAC system is integral to maintaining its efficiency. Irregular air conditioner servicing can lead to several problems, including decreased efficiency, higher energy bills, health issues, and unexpected breakdowns. 

When systems are regularly maintained, they are thoroughly sterilised and have the dirt and debris that builds up throughout the various parts and filters removed. If your split system or ducted air conditioner isn’t properly maintained, it can cause a range of inconvenient and costly issues. 

Here’s what you can expect if you don’t service your AC unit annually:

Poor Indoor Air Quality

Did you know that poorly maintained air conditioning systems are contaminated with grime, dirt, mould, grease and other pollutants on the coils and filters? This greatly affects the air quality which your family breathes.

Bacterial Growth

Even though not always visible to the human eye, mould and bacteria can build up in your AC system. Without regular servicing, your air conditioning system could cycle unhealthy air through your home.

Allergies & Asthma

Over time, poor maintenance can exacerbate allergies, asthma and other respiratory illnesses. If family members are sensitive to pollutants, this can have severe health effects.

Poor Performance

When the filter becomes blocked from dust, pollens and other airborne particles, the airflow through the fan coil is decreased, and subsequently, the system lacks cooling ability in your home.

High Electricity Bills

Contaminants reduce airflow through your air conditioner, making it harder for your AC unit to heat or cool and adding to the heat load on the fan motor. If not frequently maintained, your energy bills can spike from the system working inefficiently.

Breakdowns & Repairs

Air conditioner repairs can be costly, time-consuming, and overall inconvenient, especially in the peak of summer or winter. A regular inspection and professional check of the system can highlight any loss of performance or problem, preventing a breakdown before it happens

one of our specialists today.

Split System Air Conditioner
Servicing Sydney

Your home air conditioning system is something you use throughout the entire year. You rely on a reverse cycle split system to keep the temperature down in the hot Sydney summers and stay toasty during the frosty winter months.

The filters, coils, and fins are the most important components of your split wall aircon unit. These need regular maintenance to keep your air conditioner working efficiently and safely. 

Signs your split system air conditioner needs servicing include:

 

  • It’s been more than a year since your last professional service 
  • Air from your split system smells mouldy or stuffy 
  • A decline in cooling performance or airflow 
  • Increase in allergies or asthma symptoms indoors
  • Your electricity bills are increasing inexplicably 

Here at Alliance Climate Control, our air conditioner maintenance services will make sure you’re never without cool air at home when you need it. Call us to book your split system air conditioner service and maintenance tune-up.

Ducted Air Conditioning
Servicing Sydney

Specialising in ducted air conditioners, our trained HVAC technicians here at Alliance Climate Control have years of experience in ducted system maintenance. When we service domestic air conditioners, we look for any issues that may worsen with time to help you get on top of it now.

Some specific signs your ducted air conditioning system needs servicing include:

  • Some vents have less cooling or poor airflow 
  • There is a constant humming noise from the unit 
  • Water leaking into the ceiling or from the AC unit 
  • Dusty or bad-smelling air coming from ductwork 
  • It’s been over 12 months since your last service 

At Alliance Climate Control, we can also clean ductwork for ducted air conditioning systems if required. If we pick up any ductwork damage or leaks, we can arrange duct repair or replacement to keep your central AC system functioning efficiently. 

Call us today to book a ducted air conditioning service with the friendly team at Alliance Climate Control.

How Often Should I Get My Air Conditioner
Serviced?

Air conditioning systems need to be serviced roughly once a year, sometimes more, depending on the frequency of use and the type of system you have.

If you live in a particularly hot part of Sydney or use your home air conditioner much more frequently, it may need to be serviced more often. 

If you want to maximise the lifespan of your domestic air conditioner, having your system serviced every six months will significantly add to the life of your system.

If you haven’t had your air conditioner serviced this year or can’t remember the last time it was done, it’s been too long. To ensure your air conditioner lasts through the hot Sydney summers, it’s important to have your residential system serviced regularly.

As one of Sydney’s leading air conditioning maintenance professionals, Alliance Climate Control can provide you with a range of air conditioning services, including regularly scheduled air conditioning maintenance, so you won’t have to worry about forgetting an appointment again.

Air Conditioner Corrosion
Protection

Air conditioner corrosion can be expensive, especially if not caught in time. Corrosion can cause air conditioner parts to wear out quickly, including the fan and compressor.

Corrosion can be caused by several things, including water leaking into the air conditioner from the inside or outside, moisture getting on the coils or condenser, and even chemical vapours from paint and cleaning agents. Here at Alliance Climate Control, we offer a two-step corrosion protection plan that will help keep your air conditioner in good working order for up to 5 years.

Some of the benefits of the Alliance Climate Control coil corrosion protection program include:

  • A natural water-based coating to protect your system
  • Abrasion resistance, prevent aggressive rust corrosion on your air-con coils
  • Green, natural products which are safe for use and good for the environment
  • Over 40,000 hours of corrosion resistance
  • A much more affordable rate compared to corrosion specialists

     

Keeping your coils safe from rust and corrosion is important to your system’s overall health.

We had our old Daikin air con replaced by Yunus, Can, Veysel and Brody. These guys were fantastic. Arrive on time and from that first meet have been great to deal with. Very professional and polite. Throughout the process Yunus explained to me what they will be doing and kept me updated. Their workmanship has been great and have laid drop mats to protect the flooring and cleaned up after themselves. Overall awesome work and a very happy and satisfied customer. Well done to Yunus and his team

I’m very impressed with Kody’s professionalism during the air-conditioning diagnostic at my apartment. He thoroughly explored all possible options and was careful not to jump to conclusions, which really demonstrated his patience, expertise, and integrity. It was clear he was focused on finding the right solution rather than being money-oriented. The team also went above and beyond by waiving the initial call-out fee due to a booking error, which was a very appreciated and thoughtful gesture. Highly recommend their service. Wishing Kody and the team a Merry Christmas and a Happy New Year! **Adding on post 1st visit** Following my initial review, I had to call Kody back as my aircon started leaking after the first visit. We discussed a repair that might involve cutting into the gyprock to resolve the issue. On the day, Dylan, Colin and Ioannis attended and were extremely professional and accommodating. Instead of immediately cutting the gyprock, they took the time to explore alternative solutions and managed to fix the issue without opening up the ceiling, which I really appreciated. Big shout out to Ioannis as well for offering to patch up some paint on the ceiling free of charge - a very thoughtful gesture. Really impressed with the team’s creativity, professionalism, and willingness to go the extra mile. Highly recommend them. *Adding new review 2026* Charlie, Aaron and Sean has been nothing but professionalism from start to finish. Thanks for your help in squeezing in the last-minute appointment and tackle the unexpected hurdles during your visits. I really appreciate your friendliness, professionalism and workmanship. Cheers guys!

Hard-working and diligent fellows all the way to the disposal of the old unit and the clean-up. That company is well-run! Recommended.

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.

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.
