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.

Andre was the only real and main highlight of the entire process of having a unit installed. He was extremely helpful, did things he clearly didnt have to and went above and beyond. The experience before he came to resolve a problem that occured, was not the greatest at all and we were quite disappointed. But im very glad Andre was the final technician to help as it left a much more positive note for us. Thank you Andre.

⭐️⭐️⭐️⭐️⭐️ 5 Stars – Outstanding Service from André! I’ve dealt with many people at this company, but André was truly exceptional. He recognised that our issue may have been misdiagnosed previously and went above and beyond to get to the bottom of it. After months of problems with our machine, he is the first person to give me absolute confidence that it will finally work as it should. I cannot thank him enough. I felt compelled to leave this five-star review because outstanding service like André’s deserves to be recognised. He is an absolute asset to the company!

Fantastic service. We have just bought a new house in Northbridge and moved into the property. The air conditioning wasn't working well. We brought in an air tasker to do a general assessment. He immediately pinpointed that one of our ducted systems wasn't working and it was going to be a complicated job. He recommended Alliance to us and also recommended Daikon’s air conditioning units because they were so quiet. Within a few days we had somebody come round from Alliance and spend a lot of time on the property checking out whether we could replace the ducted system or whether we would need to go with the split system. It was a much more expensive job than we expected and the guys did everything to try and get us a keen price. We really appreciated everything they did. The installation team turned up today, all bright smiles and lots of enthusiasm, and were so, so careful around the property. They laid sheets everywhere and put clean plastics around things like wardrobes so there was no dust. They were so clean and tidy. They worked like troopers all the way through the day and after 10 hours of work it was finally done. They swept all the stairs, cleaned everything away, and even had a little goody bag to say thank you. They were absolutely fantastic and I couldn't recommend them enough, especially this particular team. He was so careful and thoughtful with the house.

It was refreshing and pleasant dealing with the Alliance Team that worked at our premises. Alex assessed what was required and provided the quote. On approval Alliance sent their Team Yunus, Peppe and Jacky to execute the job. They arrived on time( there went my sleep) and had the air conditioners installed by midday. They were also accomodating with a light globe and skirting around an adult dog and puppy. Thanks guys. Leslie.

Alliance Climate Control went above and beyond what I expected with our air con installation. They were exceptional. Installing AC in our loft apartment was not straightforward. Alliance helped us respond to the questions we got from our Strata Committee, adapted the scope of works and did what they said they would do. The installation team of Garrett, Shabi and Daniel did a great job. The internal trunking is almost a work of art. They did such a high quality job. They also took great care with our furniture and walls, using covers and drop sheets to protect everything. As the work involved cutting holes in our ceiling and walls, another team - Meedy and John -did a superb job in fixing up all the surfaces. (And reinstalling our electric blinds). Thanks guys. We got 5 quotes for our AC installation. Alliance are a bit pricier than others but geez it is worth the extra. They delivered the goods. We are very happy with the end product.

We had trouble with our air con unit and had Alliance come to check it. Throughout the process we had a number of team come out to do work and all of them were fantastic. Very polite, clean and friendly. Kyle was awesome helping resolve the issues and going through options, Tommy, Shaad and Mussef did a great job on the instal with an extra visit from Matt. Then there was phone support from Alfie. I will have no hesitation in recommending them to others.

My family and I highly recommend Alliance Climate Control! They just finished installing a Daikin air con system at our place in Turramurra. The guys who came out were super polite and friendly from the moment they arrived. They did a fantastic job with the installation, cleaned up after themselves and left the house absolutely spotless. If you need an air conditioner installed, definitely give these guys a call!

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.
