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:

particles-icons

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.

particles-icons

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.

particles-icons

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.

zoning-icon

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.

particles-icons

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

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 Health Check-Up & Report

At Alliance Climate Control, we understand the importance of regular servicing and maintenance, so when we perform your regularly scheduled service, we go above and beyond to check every aspect of your air conditioning unit to ensure it runs as efficiently as possible.

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

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

Elle Jay Q.
We didn't go ahead with the quote, only because another company fitted our needs more closely, but I would still 100% recommend including Alliance as part of who you call when looking for aircon. Liam Doyle quoted us and he was very knowledgeable and friendly. I would definitely advise calling them if you need aircon.
Darby J.
From start to end excellent professional team, great communication, very well organised and coordinated, installation teamwork was superb, clean up was very well done.
James, Tommy, Matt, Miguel and Harry were all excellent, courteous and respectful of working in our house.
Overall they were a team that I would have back again and recommend to any future customers.

Helen R.
It was raining heavily the day the Alliance Climate Control technician came to my house to provide a maintenance and check up for my two air conditioners. He carried out the job, working both inside and outside without complaint (about the rain). He was on time and efficient. I have confidence that he did an excellent job. Thank you.
Jay K
Dragon and his two mates were very polite and respectful, they drilled the wall from both sides to minimize the chipping, installed everything nicely, and completed the job on time. I am really pleased with them.
John M.
Good job.
Aaron J.
Wow! I called Alliance Climate Control to get some advice on my ageing air-conditioniers and from that moment on, it was a pleasure to deal with such a customer focused company. After emails / texts from Head Office explaining the process, Raj turned up to give me a diagnostic report on my almost broken air-conditioning system. After explaining all of the possible scenarios, I decided to purchase a new system. Team Leader Vy and Cristian turned up a couple of days later and from that point on, it was all systems go. Everything was explained simply and professionally as the process went along. Other technicians turned up ( Harry, James and Moller) to help with the installation (which at some points was more difficult than expected due to my ageing terrace house) and it was all carried out in an expert manner.
I would highly recommend Alliance Climate Control for any air-conditioning needs.
spencer B.
Great team very professional
Levi's D.
Kyle was very professional and courteous.
Kim
Alliance installed a Daikin 15.5Kw ducted unit one week ago. The team of Garrett, Lewis and Qais worked really well together. Qais was particularly impressive with his work ethics.
Also, Harry who did the plastering, and Yiannis who finished the job off with very careful painting of our ceiling.
Peter K.
Our old ducted air conditioner failed, so we contacted the team at Alliance for a replacement. They provided a competitive quote and completed the installation quickly. James Greene thoroughly explained the process and presented us with several options. Alliance offers exceptional before-and-after sales service, and we have enjoyed trouble-free air conditioning for the past two summers.
Michael W.
Tommy, Miguel and Nick did an excellent installation. Very tidy and neat.
Andrew L.
Alliance were outstanding from start to finish. Made an initial enquiry and James came out the next day. Comprehensive quote on the spot. Accepted and the whole install was done the following week - ducted system and two split systems. Install team of Yunus, Gokhan and Emre were outstanding - courteous, clean and knowledgeable - and worked hard. I'm a pedantic customer - and part of the house is very old - they were more than happy to be accomodating and sort any issues I raised. Very pleased with the quality of the work and the team - would highly recommend.
Rod W.
I needed to replace a reverse cycle central air-conditioning system that was about 20 years old and add a smaller new system in a different part of the house. I decided to use Alliance Climate Control after doing some research meeting their salesperson at my home in a very productive exchange.
Gerald B.
Special thanks to Tommy, Nick and Miguel for their excellent work
jessie R.
This was my second aircon clean and service from Alliance. Both times the techs were on time, pleasant, and knowledgeable. I wouldn't now use anyone else.
Peter H.
What a pleasant and professional service Alliance Climate Control provided. From the initial phone contact to the friendly, courteous, and efficient service provided. Alex arrived on time checked both units and kept me informed at all timers as to the best solutions. We then had BJ, Daniel and Brandon install a new Daikin unit. As mentioned when it was booked they covered furniture and did a clean install. Zac also deserves a mention as coordinating and ensuring a smooth operation made it seamless. Thank you Alliance Climate Control for making it an professional experience, highly recommend.
Scott K.
The Alliance Climate Control team, from engagement, quotation, installation and customer support was excellent. The ACC install team of Tom, Nick, Miguel, Matt, Benjamin and JJ were very professional in all aspects of the install and commissioning. Would most highly recommend ACC.
Inti R.
Tommy and Nick were absolute legends, they did an aircon relocation from my living room to my attic. both Tommy and Nick did the job with no fuzz, fast efficient and more importantly quietly. I was working from home through the job, and they needed little to nothing from me once they were setup and ready to go. The aircon was moved professionally. Thank you!
karen S.
Great service. Very professional. Highly recommend.
Mary J.
BJ,Daniel, Brandon Aysa, Zac Peter & Aden.
From the first phone call thru to quote job & clean up to showing me the easy to use remote. Have all been wonderful, professional installation fantastic & very thorough with prep, covering furniture and clean up afterwards.
This was a very considered purchase.
I'm so happy I chose to go with Alliance.
Philip M.
BJ, Daniel, Brandon, Chris Divis & Zac were all very professional the service we received was excellent. Highly recommend them. Good Job All Round.
Maurice N.
Outstanding staff. Punctual, clean, knowledgeable and efficient.
chi-kan W.
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.
Lia
A big job completed with ease and professionalism by ACC, so happy my place is now cool! From James Greene’s initial quote to the install team of BJ, Daniel, Brandon, JJ, Vash, Blade and Giannis, plus Zac and Eric and Will and Joe behind the scenes, everyone has been delightful to deal with. Highly recommend
Gennaro S.
Professional Team , efficient and very pleasant to deal with . Wonderful service by Tommy ,
Nick and Chris , Vash and Blade .
Brett D.
We have a two level house with 5 bedrooms 3 bathrooms lounge room family room and kitchen
We needed a system to do the whole house
I had two quotes both of which the gentlemen giving the quote were at my house for no more than 30mins.
Darko from Alliance came and was totally professional and inspected the house roof cavity and all. He then sat down with me and discussed the system that would best suited, he explained the installation process and how Alliance worked in all he was here for over 2 hours. It is because of Darko knowledge and commitment we decided to go with Alliance.
The installers arrived on time being Matt,Aaron,Mahalo and Andre. They worked here for 3 days putting in the system. We were totally impressed with the way they worked and the quality they delivered. They were also courteous, respectful and ensured they cleaned up after every day work. TRUE TRADESMEN

WE could not rate the people we have dealt with from Alliance Climate control, highly enough. From the time of quotation to the time of installation we were constantly informed of what was going on.

So from us its a 5 out of 5 for everyone involved from Alliance Climate Control in giving us a great Air Conditioned house
Sam D.
Great service options and very detailed work. Highly recommend
