Window & Wall Air Conditioners — Affordable Cooling Solutions
Most times, especially in the summer, you just want a cool space. But not every room needs a split system. A full split system can feel like overkill. Not every budget can stretch that far either. Sometimes you just want one room cooled efficiently, without turning it into a renovation project.
This is where a window & wall air conditioner shines. They are compact, all-in-one air cooling solutions for home use. Your home experiences reliable cooling without the extra cost, hardware, and installation complexity of a split system.
At Current Force, we stock Kelvinator window air conditioners in multiple capacities (2.2kW, 2.7kW, 3.9kW, 5.3kW, 6.0kW), with options for delivery and installation support depending on your location
Why Choose Window Wall Air Conditioners?
A window or window mounted AC is a single-unit cooling system that sits in an opening facing outside. All the key parts are inside the one body. It mounts through a window or external wall opening and vents heat straight outside.
Because of this, you skip a lot of the usual headaches that come with a split system. If you’re cooling a single room or smaller area, they often make more sense financially and logistically than installing a split system.
These are the great benefits of a window and wall air conditioner:
- A lower upfront investment. Less equipment and simpler installation usually mean a more affordable starting point.
- Quick, contained installation. No outdoor condenser, no extensive cabling, just a properly fitted wall or window opening.
- It is ideal for rentals and small spaces. If permanent changes are not possible or when you only need cooling in one part of the property, this is a perfect option.
- Straightforward operation. Set the temperature, and let it run. Nothing complicated.
- Reliable, proven day-to-day performance. These units have been around for years for a reason; they are proven and consistent.

People sometimes forget about these units because split systems get all the attention. But window-mounted ACs are still one of the most straightforward ways to get room-focused cooling. It is one of the most affordable air conditioners out there.
Here is a quick summary:
| Window & Wall Air Conditioner | Split System | |
| Upfront cost | Usually lower | Often higher |
| Installation complexity | Simpler (depends on aperture) | More complex (indoor + outdoor) |
| Best for | Single rooms, rentals, small offices | Whole rooms/zones, long-term setups |
| External components | None separate | Outdoor condenser required |
| Flexibility | Great for quick installs | Best for permanent installs |
| Cooling focus | Room-by-room | Room or multi-room options |
If you’re trying to cool one bedroom, a small living area, or a compact workplace, a window-mounted AC can be the sensible choice. If you’re planning long-term whole-home comfort, a split might be great. Ultimately, they are different cooling systems for different jobs/needs.

I highly recommend Current Force, Jason was a pleasure to deal with. He promptly answered my many questions and was more than willing to deal with the challenges of installation in my top floor apartment, which has some access issues – other companies were either not able to do the job or gave me quotes that were significantly higher. The installation process itself was very efficient and I am very happy with the result.

Jason and his team did a great job of installing 3 Mitsubishi split systems in a new townhouse build. He was very easy to deal with, provided several options and was the most reasonable quote out of 3 quotes we received. Very happy and looking forward to using the aircons this summer. I highly recommend Current Force.

Jason and his company is highly recommended. He installed my split system exactly where I wanted without fuss. He did a very neat job, cleaned up after himself, was quick, arrived on time and very professional.

A great experience - I sent out a few quote requests with photos of the site via email. Jason from Current Force politely followed up with a call to clarify some details to ensure he could quote correctly. The quote came back very competitive for both the unit and the installation - Jason also mentioned there was a limited cash rebate period still going with this particular brand. He made every effort to schedule the job in at a very acceptable timeframe. Jason was professional and very courteous, he explained all the functions of the remote control, everything was left clean and the boxes were taken away. On time and on budget, no surprises. Judging by this installation I would not hesitate in recommending this company.

From the moment I contacted Current Force I couldn't be more pleased. Jason contacted me soon after and although not being very technically minded I uploaded photos (quite simple) of where the unit was to go and received the quote and good advice soon after. They were punctual, very friendly and professional and did the job in a timely manner. I would certainly recommend them without any hesitation whatsoever. Thanks for a great job!

We received a lower price from CurrentForce through Jason compared with 2 other companies, and ended up with our 2 systems (2.5kw MITSUBISHI) fully installed within a day to a very high standard (acceptable to our Body Corporate). Many thanks. noted for future business!
Daryl Raggatt
Great service onsite and over the phone when discussing the placement of the airconditioners within the house. Would recommend without a second thought.

Frequently Asked Questions
What is a window & wall air conditioner?
It’s a single, self-contained air conditioner that fits through a window or external wall opening. Everything’s built into the one unit (compressor, fan, controls, etc.), so there’s no separate outdoor box sitting outside the house.
Think of it as an all-in-one cooling system. You just slide it in, secure the air conditioner, and plug it. You are basically good to go. It cools the room it’s in directly, without needing extra pipework or complicated setup behind the scenes.
It is simple by design.
How do these differ from split system units?
Split systems use two parts: one inside, one outside, connected by refrigerant lines. They are great, but installation is more involved (drilling, mounting, electrical work).
Window & wall units keep everything together in one body. No external condenser and no long pipe runs. That usually means quicker installs and lower upfront costs.
If you’re cooling a whole home, a split might be a valuable choice. But for one room or a small space? A window unit is often the more practical (and less stressful) option.
Can they be installed in any room?
Not quite any room. They do need an external wall or window opening, so the heat can vent outside. Without that, there’s nowhere for the hot air to go.
Most bedrooms, living areas, and offices are fine, though. As long as there’s outside access and enough space for the unit, you’re usually covered.
If you’re unsure, send us the measurements or a quick photo.
Are they noisy?
No. However, it is not completely silent. You will hear them running, and that’s normal for any kind of equipment.
But modern models are miles quieter than the older ones people remember from years ago. It is more of a steady background sound, similar to white noise or a pedestal fan. Overall, it is not a disruptive air conditioning system.
Do you install these units?
Yes, we can help with that. Current Force offers delivery and installation options, depending on your setup and location. Some replacements are straightforward, especially if there’s already an opening. However, new installs might need a little more prep work. Call our team today to know more.
What capacity should I choose for my room size?
As a rough guide:
- Small bedrooms or studies → 2.2–2.7kW
- Medium rooms or offices → around 3.9kW
- Larger living areas → 5kW+
But factors, like sun exposure, ceiling height, insulation, and even how many people use the space, can change that. If you’re not 100% sure, give us a call. We’ll help you size it properly.
Do these units offer heating too?
It depends on the model. There are cooling-only units, and there are reverse cycle versions that can heat as well. If heating is important, let us know upfront, and we’ll point you to the right option.
Is installation included or separate?
You have got both options. You can purchase the unit on its own if you already have someone installing it, or you can bundle installation with us and keep everything under one roof.
