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.

Karim M.
Charles and Aaron arrived on time and were patient and professional while answering all of my questions. They provided clear, written quotes, explained exactly what was included and what wasn’t, and even suggested and implemented a solution on the same day for a problem that wasnt even part of the job they initially came out to do.
Maria M.
Extremely impressed with Shaby, Michael and Benjamin from Alliance. Professional AC installation work, polite and friendly and very helpful. I would highly recommend these guys and the costumer service team from Alliance .
Helena M.
From the very beginning I knew I would receive good service from this company. The lady that answered the phone ( Kayley I believe) was very efficient in assessing what I needed and organising a supervisor to come in and arrange quote. That was Alex - he was very straightforward and a very good salesman!! The service itself was also straightforward with two techs coming in (Mitiesh and Nick) and they just got on with it while dealing with a very curious pet! Overall a very positive experience and I will be signing up with them for regular maintenance and refer the company for anyone who has a similar issue that I had. Thanks
Anne B.
We were very pleased with the whole process. Thank you.
William B.
Service Technician arrived within the advised block time. He carried out the required service very efficiently and provided a written report of the condition of all aspects of the A/C and cleaned all the filters, unit cover and the outdoor unit. Very satisfied with a thoroughly professional performance.

C W.
Had new AC units installed and an old one replaced. My experience with ACC and their team was fantastic from start to finish. The team that supported us included Liam, Vash, Will, B.J, Theo and Jun. Cannot thank them enough for being such a pleasure to work with. They were incredibly professional, good at what they do and showed great care in helping us with our installations. I would highly recommend ACC and this team! Thank you to the Team again!
Christopher W.
I recently had air conditioning installed by Alliance Climate Control and couldn’t be happier with the experience. From start to finish, the service was outstanding.

A special mention to Vy, Luan, and Eric, who did an exceptional job on the day. They were professional, punctual, and clearly took pride in their work. The installation was carried out efficiently, with great attention to detail, and they left the place clean and tidy afterward. They also took the time to explain everything clearly and made sure the system was running perfectly before they left.

Highly recommend Alliance Climate Control to anyone looking for quality workmanship and excellent customer service.

When our apartment’s 12-year old Daikin air-conditioning system broke down, we called a few A/C companies, including Alliance Climate Control (ACC). We were immediately impressed by ACC’s professionalism, promptness and very friendly office staff and service technicians. Shazin and Brandon did an excellent job diagnosing the system’s problems and providing a range of options as to its repair and on-going guarantee conditions. Once contracted, Yunis, Nico and their colleague (whose name, regrettably, I have misplaced), took great care in replacing the larger components on the building’s roof and replacing the five individual control panels in our apartment. Not a trivial job, given the roof accessibility in our building. Conner and Steven worked hard on a following, very hot day to diagnose and correct a tricky leak in the coolant pipe on the roof that runs to the apartment. With the pipe sealed, they commissioned and tested the system thoroughly. ACC kept us well informed throughout the entire process. We are very happy with ACC and have no hesitation in recommending them!
michelle F.
Absolutely wonderful service from JJ and then 2 guys today Charles and ? They very professional and just nice guys. Thank you
David Y.
Job #100840 Andre was punctual, presented himself well and knowledgeable. He was thorough in his servicing and we're happy with the results.
Jaime P.
We recently bought our first home and when our AC started leaking into our ceiling we were so panicked. The Alliance team were so helpful, they got out to us quickly and gave us a very honest assessment. We were lucky enough to have our new AC installation completed by Qais, Cris, Eric and Mike and they were fantastic. They were so professional and super fast, we have been so happy with the service and are so glad we decided to employ Alliance to replace our old unit.
Joshua S.
BJ & James did an excellent job installing our new Daikin split system…they were on time, professional and very tidy. Vash & TK did the electrical wiring and were great to deal with too. Aysa did the original quote and was brilliant, great guy and very helpful. Also spoke to Will & Cara in accounts. The Alliance guys are a super team and I would definitely recommend them for all your a/c needs!
Elisabeth M.
Friendly, helpful and competent.

Boys turned up before time explained as they were going and did an excellent job more than the previous company had done Emre and his assistant were great took there time and did the job.Excellent work even though was only a service on two different units
James W.
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!
Geni S.
On time. Detailed report. Polite service. 3rd year annual service. Highly recommend.
Mimi S.
Great team. Thank you Kim, Brody and shout out to Tommy for all his roof skills on such a hot day.

I had an excellent experience with Alliance Climate Control installing the air conditioning unit in my shop.
The service was fast, clean, and extremely professional from start to finish.

Yunus, arrived ahead of the shop opening, took the time to understand our needs, and recommended a unit that was perfectly suited to the space. His colleague Gokhan was also incredibly helpful throughout the installation.

Both were polite, discreet, efficient, and worked with great care. They left the place spotless after the job, which I really appreciated.

I highly recommend Yunus ,Gokhan, and Alliance Climate Control and would absolutely use their services again. Outstanding work.
ian L.
The three contractors, Yunus, Can and Veysal were the most pleasant and courteous workers. They spent two days installing my air-conditioning in 40 degree heat in the ceiling and didn't complain. I would highly recommend them.
Sasanka D.

The team who came out (Andres R/Christian C/Dilan) were fantastic with replacing the ducting putting the new unit in.

Shin K.
Amazing service - thanks to Shabi + Benjamin + Nicholas for their hard work especially on such a hot day - superb service

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.
