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

The job went perfectly, with a successful outcome: a new, relocated, up-dated electrical circuit board. The electricians used previous openings, the wall cavity, etc. to minimise changes in appearance. The members of the team were all extremely helpful and communicative: Charles, Ryan, James and Aaron

Today, a fantastic team of five technicians – Jonathan, Juan, Andre, Gok, and Shaad – came to our home in Earlwood to install our new gas ducted heating system, and we couldn’t be happier with their service. They arrived right on time, worked efficiently, communicated clearly throughout the installation, and completed the job to a very high standard by. The whole team was professional, friendly, and respectful of our home. A big thank you to Jonathan, Juan, Andrew, Gok, and Shaad for all your hard work.

V led the air con work, Liam led the plastering. Both were very competent and a pleasure to work with. The job in the aggregate took way too long but I understand that was a break down in company communication between quotes and execution of work.

Just had a cleaning service for our split system in ceiling cassette Fujitsu system and I have to say it was well worth it! I was concerned of the cost at first, but after having the system for close to 16 years, I now hope to get a few more yet. The guys who did the work Mitiesh and Brandon were wonderful - professional, clean, informative, careful and thorough. I would recommend this service

The job Alliance was doing for me appeared straightforward at first but when rummaging in the guts of the electrical configuration powering my old house, a problem was found. The cavalry was called in and the problem resolved with only a minimum of expletives needed. Many thanks to Aden, Mo and Ryan. Charles too.

We decided on Alliance after much consideration and are happy with the installation so far. The team of BJ,Theo, Andre and Matt were all personable and diligent workers and explained things to us as they went along with the. installation. My only slight issue was that I received too many phone calls from different numbers and initially couldn't tell from where the call originated or if it was a spam call. I feel a single source of contact would be preferable at least until the commencement of the job. But all in all, I am satisfied and pleased that we chose Alliance

I highly recommend Alliance Climate Control, especially their electrician Charles. Charles was extremely friendly, professional, and arrived exactly on time. The work was completed quickly and efficiently, and the quality of the job was excellent. What impressed me most was his attention to detail and the fact that he cleaned everything up afterwards, leaving the area spotless. It’s refreshing to deal with a tradesperson who is reliable, respectful, and takes pride in their work. A fantastic experience from start to finish. Thank you, Charles and the Alliance Climate Control team!

Easy and stress-free process from quotation through to installation. James was great to deal with during the quoting stage, and Meedy and Christian delivered an excellent installation. What stood out most wasn’t just their expertise, quality workmanship and product knowledge, but how genuinely happy they were in their jobs. Meedy mentioned that their boss had taken the team to the pub the week before, and it was clear that the company values and looks after its employees. As a customer, you can feel that positive culture. There was a genuine warmth and enjoyment in the work they do, which is something you don’t often come across these days. When people are looked after, it shows in the way they treat their customers. I honestly haven’t had a conversation with tradespeople like that in a very long time. The quality of the work was excellent, but seeing a team that genuinely enjoys what they do was probably the highlight of the whole experience.

Great experience…thorough, friendly, inc sales pitch on the service agreement , but as a courtesy when in someone else’s house…please ask to use the loo. Two occasions. Not asked. Takes 2 secs. Should be a company directive.

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.
