What is a Window Wall Mounted System?

A window wall-mounted system, otherwise known as wall-mounted or box air conditioners, is a simple and convenient way to deliver airflow to any room of your choice. Once installed, this singular unit can provide a comfortable climate to any living space, office, or bedroom.

Designed to be visually unobtrusive and completely self-contained, the window unit comes as a robust steel cabinet. All necessary components are available here for convenient servicing, making installation efficient by requiring one access point.

If the unit is being retrofitted to an existing building, it will generally fit within half the width of a normal window space. If being installed in a new structure, or where permissible to make an aperture in an outside wall, it may be located wherever most suitable.

Window Wall-Mounted Air Conditioning Services

When you need temperature control in a single room or small space, consider the cost-effective solution of window air conditioners.

Alliance Climate Control has years of experience in installing and servicing a wide range of systems, including window units. The addition of our extensive training and dedication to customer satisfaction allows us to tailor window system offerings to you.

Installation

Window Wall Air Conditioning Install

Most window air conditioners, including those provided by Alliance Climate Control, can be installed in a window frame or wall. We have the necessary training to provide clean, timely, and long-lasting installation services, regardless of the unit’s location.

Alliance provides all customers with a detailed, on-site assessment before all installations. That way, we determine the best location for your new unit that provides optimal airflow year-round.

Book a consultation and allow one of our local teams to promptly answer your call. We’re always dedicated to going above and beyond for your HVAC needs.

Replacement

If window air conditioners aren’t providing the same level of climate control or energy efficiency, even after repairs, it may be time to get your unit replaced. Fortunately, Alliance makes the entire experience as simple and hassle-free as possible with our local technicians.

On the day, we will handle all the hard work that comes with removing and replacing an existing window air conditioning unit. We dispose of the old unit for you and install the latest system right away, providing any necessary work to prepare your home for this new addition.

Alliance even offers beneficial rebate offerings for those interested in saving more when they replace their old AC. Check it out to see how you can save today on your scheduled removal.

Repairs

To ensure your window air conditioner provides cooling and heating services throughout the year, don’t hesitate to book a repair appointment. It’s a cost-effective solution for many units only experiencing minor issues, especially when compared to the more costly work of replacement.

When you notice symptoms such as loud noises, bad odours, leakage, or other concerns coming from your AC, you may need repairs. Alliance ensures your system is working at peak performance, assessing critical components functionality and that filtration mediums are free from dust or pollens.

If you want to save more time, money and concerns by maintaining your existing unit, consider a repair appointment.

Cleaning

The values of Alliance Climate Control aren’t just centred around ensuring customer satisfaction and excellent HVAC work. We also pride ourselves on providing environmentally-friendly operations, regardless of the window AC work required.

This can be seen in our approach to professional HVAC cleaning. Our focus is on creating a home that’s air-pollutant-free and has an optimal AC system upon completion. We also happen to do this work with eco-friendly cleaning products tailored to fully restore the operation of the fan coil and filter in your window system.

An Alliance Eco-Clean service is recommended for your system at least every alternate year, to keep it in top operating condition. That’s because it best prepares your window AC for high heat loads during summer and the need for consistent warm air during winter.

Maintenance

Regular HVAC maintenance ensures your system operates at its full potential with minimal wear and tear. Window wall-mounted systems often sit in the framing of your home’s windows, exposing them to outside elements. Hence, scheduled maintenance is also crucial for extending the life of the air conditioning system.

The convenience of having all components in a single unit makes this an efficient job when performed by Alliance. So, schedule a visit from one of our local technicians and enjoy the following features of professional maintenance:

  • Extending your unit’s warranty
  • Lowering overall energy costs
  • More reliable performance over the seasons
  • Prevention against future issues
  • Reduced number of AC breakdowns
  • Visit from a licensed electrician for any additional installation work

Why Choose a Window Air Conditioner for Your Home?

With plenty of air conditioning systems on the market, why choose a window unit to install in your home? For many Australian households, this singular unit addition may be preferred due to the following factors:

 

  1. One of the easiest systems to install, whether that’s through new or retrofitting existing AC installation services
  2. Due to the simplicity of the installation, it’s one of the quickest services possible, especially when done by HVAC experts
  3. All components of the system are contained within a robust cabinet, keeping them safe while also providing a convenient access point for all repairs, cleaning and maintenance
  4. Heated air exhausted from the condenser cooling process is easily vented to the room of your choice
  5.  Oscillating vanes provided in the cabinet direct conditioned air within the room from side to side or up and down, providing flexible airflow as needed
  6. The unit can often be plugged directly into a normal single-phase household power point, meaning no additional electrical services are required
  7. Operations are known to be quiet, with sound levels not exceeding 50Dba to create a tranquil environment
  8. The simplicity of the model and its accompanying services often makes it more cost-effective both short- and long-term than other systems

If you want to know more about how this product can potentially aid your home’s climate control, our team is always ready to offer expert insights. Feel free to give us a call, and we can assist you in assessing what kind of air conditioning support your household needs.

rada P.
Liam was fantastic. Very friendly, clean and job well done. Highly recommend Alliance. Always such a good service. Have used many times and will continue to. Keely also super friendly and helpful giving me eta so I wasn’t waiting.
Amith S.
The service and follow up was prompt and as promised... We had a 9 year old AC unit which had stopped cooling and making unsteady noises... The initial review and assessment to change the unit foundations which was rotting and a service was point on. The service person was prompt, very kind and mindful despite the difficult access to the roof unit. Have to say, the only issue I'd have was the initial inspector and quote pushing us to replace the unit for double the service price which in itself was a bit pricey, but in these days a full days of work it's expected. All in all an happy customer, as happy to pay a premium for a job well done! Great service - definitely will use again.
Mary
Explanation and co-operation from go to woe. Couldn't be happier 😁
Jennifer F.
Replacing old gas heating system with new heating and cooling system. I was impressed with Jake’s knowledge when he came out to quote the job, then the Installation team was very experienced and professional, good communication and provided onsite solution. I am very happy with the result, thanks to Vy, Lyn, Eric & Peter.
Eric T.
We got AC for our North Bondi house and could not be happier.
From initial conversation Aysa came up with a very genius plan for placement installation of the AC. Installation team Gokhan, Louise and Charles was so helpful and made the idea happened
They were so clean, tidy up everything and super knowledgeable. They did a schmick job.
Many thanks guys 🙏🏻
Allan L.
Happy with the work done, clean up and respect for our property by Ivan and his partner (sorry name forgotten). Follow up plaster work was also done well and Liam is to be commended.
Ugur O.
Charles and Arron did a great job installing the pendant and outdoor lights. Took great care to leave everything perfect and clean.
Simon van W.
We installed our air conditioning 5 years ago. The installation was perfect and we have had no issues in all the time we have owned the system. We had to get them back because one unit was leaking water. They were prompt to attend to the problem, admitted that some of the problem was their issue and they would cover the fix themselves.

They owned the problem. They are always very polite. The engineers they send out are highly professional, leave no mess, take off their boots and are good at communication with the client.

I've recommended them to many people..
Tam T.
We have asked Alliance Climate Control to come and service our 2 air con systems (one central and the other, a stand slone unit). Andres - a young trademan came ontime with prior warning and did a really good job for us. We also had Kyle (?) coming later to fix a condensate leakage issue which he also did well, on time with prior phone call. We then signed a 3-year maintenance contrsct with ACC after our good experience with their workers. We strongly recommend this group, having professional and friendly staff working for the company. Thank you ACC
Ian B.
We were delighted with our experience with the Alliance team of Tommy, Nick and Luan. They went about the job professionally, expertly and with no fuss. They left the job site as they found it, perfectly clean. What a wonderful example of hard working young men and a credit to your organisation. All contacts with these young men were courteous and polite. Well done Alliance.
Angus H.
Connor and Steven completed some drainage works and also a service of three of my AC units today. They were friendly, professional and communicated excellently. Highly recommend these guys!
Christopher B.
Alliance team on time and efficient. Thanks Shabi and Louis for handling both the callouts so well.
Elliott Y.
The team Kristin, Aaron P, John M, and Chris D were as good as it gets. From my initial request with Adrian, confirmation appointment with Kristin to the actual work undertaken was all a pleasure. For me as a customer I was again impressed with their expertise and their communication. There's a lot to be said about Alliance, all good!
David B.
Very happy with the product and the installation, very professional and efficient. Highly recommend.
Clemence W.
We had Shabi, Louis and Nicolas install our aircon right before the heat wave this week. They worked really hard and we love the result.
Kathryn T.
A big thank you to the whole team for a professional and very clean job, can’t thank them enough. They fixed up our ducted system and installed a new system at the back of our house! Big shout out to Andre G for managing the ducted service, and to Gokhan, Veysel, Michael and the electrician Charles for installing the new system. We will now use them for all our servicing.
Sue H.
We were very impressed with all aspects of the installation and replacement of our outdated ducted air conditioning system. The prompt response we got from Jake, who came out to scope the job & provide a quote was very impressive. As was the turnaround from accepting the quote to the installation (3 days). The team who carried out the installation, were terrific & worked tirelessly to get the job done with minimum disruption, which we appreciated as it was a fairly complicated job. We would like to thank each of them, Jonathan, Miguel, Matt, Maisam & Ahmad, they all deserve a shout out. All in all from start to finish it was a great experience & couldn't recommend Alliance highly enough.
Steven K.
Lachlan was professional,punctual and pleasant to deal with
Roger P.

Cate C.
Service technician polite and efficient
Marcus W.
Job well done, Jason was very clear in the process before hand and also explained everything well when finished.

Update: 3 Dec

Decided to ask ACC to do some straight electrical - powerpoint installs , sconce replacement.

JJ and Aden did a great job: quick, friendly, informative. Really neat job. Cleaned up after themselves and even took the old sconces for disposal.

Happy with the work.

JJ also noticed some switches were out of code in my switchboard and recommended and completed replacements.

So house electrics are a little safer too.

AIR COND INSTALL Review:

Two teams worked on our place:

Andres , Cristian and Qais replaced our ducted system, and Vy, Luan and Maison installed a separate split system where ducted couldn't reach.

Both teams did an excellent job.

Everyone arrived on time, walked us through what was going to be done and were happy to answer any questions. They were friendly and professional. Completed install on time, showed us how the new system worked and made sure we were happy. Cleaned up afterwards too - as promised.

Ducted team worked for two days in some hot conditions, removed old unit and ducting and disposed off. Hassle free for us. Install of new system, ducting and control system was trouble free for us.

Split team did a great job too - gave advice on best position for indoor and outdoor unit, clean efficient install, tidied up after themselves. Really professional.

Great from start to finish.
M E.
Tech was nice polite guy but he did not have the correct filters and wanted to cut some down to fit .. this does not work as cut down filters do not hold their shape so I told the guy not to replace them this time although the cut downs ones that were installed last year were quite clean, they were not in good shape.
Update: the company apologised for not having the correct filters at the time and promptly arranged for the correct units to be installed .. they really do follow up and fix any issue so deserve 5 Stars
Alex K.
Alliance are the best! Garret, Shane and Louis did a fantastic job installing our new AC unit. Protective mats were placed on all floors, they removed all mess and even took away our old unit. Garret ensured we were across the installation process, asked questions when required and also informed us of how to operate the new system. Great job!
Elaine B.
Excellent and professional service from start to finish. Particularly impressed with the team who did the installation. Efficient and careful. Attention to achieving optimum performance from the system much appreciated.
Karen P.
Jake and James were efficient, punctual, clean and courteous. My AC unit is as good as new. I would have no hesitation in recommending Jake and James and I will certainly use Alliance in the future. Thank you guys.
Maria C.
We had our split system air-conditioning installed almost two years ago now (April 2024) and I have been meaning to write a review, because we were really happy with the service and installation, and I have only just got around to it. But that may be good, as I can say that the system works perfectly, and we have had not problems.

We have an inner city terrace, and have over more than a decade got quotes, only to be told that "it is not possible". So, I looked for someone close, who I figured would have experience with our type of dwelling. The quote was very reasonable, the installation went smoothly, and we are very happy.
Tracey H.
Very good service from BJ, James, Errol and Will for our air conditioner installation. Errol and Will were very responsive and flexible during the consultation and booking phases - I felt like their advice was solid and really suited my circumstances. BJ and James were an incredibly professional and efficient installation team - they got it done, cleaned up, and made sure I was across our new aircon. Would recommend.
Kylie B.
Excellent service - on time, friendly and professionally completed the job ( air conditioning & two ceiling fans). Also cleaned up and put furniture back into position.

Thank you to the team who did the work - Shabi, Louis, Peter & JJ.
Also to Will behind the scenes who coordinated the scheduling of this job ( fans added in )
Thanks again

Frequently Asked Questions

While it’s possible to install window air conditioners yourself due to their simplified design, it’s really not recommended. AC installation is best done by experienced professionals to limit potential damage or danger in a household.
Contact Alliance Climate Control to access reliable window air conditioner installation that lasts a lifetime.

The cost of installing window air conditioners depends on multiple factors, including: the unit’s size, the amount of installation work, the addition of HVAC features, the electrical work required, the condition of the window framing, and more.
Fortunately, Alliance provides upfront quotes for all installation work. We work with you to determine which window AC fits your budget for efficiency in installation.

If you have an existing standard household outlet within reach of your installed window AC, you likely won’t need a licensed electrician for the job. However, you may need to consider a professional’s aid if the unit’s too large for the outlet’s capacity, it needs more energy, or a new outlet needs to be added.

Our team also contains trained electricians capable of fulfilling these window air conditioning installation needs.

Since a window unit is typically used to cool or warm a singular room, they are often cheaper to run than other, more extensive AC systems. Yet, if you are interested in cooling or heating an entire home with window ACs, this may begin to add up more than other systems.

With regular professional maintenance, window air conditioners generally last between 8-10 years. The exact length differs depending on the quality of the unit, its environment, and other factors such as continuous use or a lack of cleaning.

Due to the need to install window ACs into window openings, this can create a blockage of natural airflow and sunlight. Once installed, window units are also non-portable, making them more inflexible than their simple design would suggest.
Additionally, these systems are usually only suitable for climate control of a single room. So, if you want a more adaptable or expansive AC system, consider discussing your HVAC needs with Alliance.

While it’s not overall bad to leave them running if it’s necessary for your comfort, some disadvantages come from operating a window AC throughout the day include:
  • Higher energy bills
  • Increased wear and tear of AC components, possibly leading to expensive repairs and/or a shorter lifespan
  • Risk of components freezing up if constantly cooling, and alternatively overheating if pushing out warm air
If you want to use an AC running all day, discuss your potential options with the HVAC experts at Alliance. We can help you find the best match for your air conditioning needs.
