Works as advertised. Quiet with remote and a good price. A good Chinese Brand – A 15 year old unit needed replacement and locally there was little choice for a wall mounted unit of this size. I have spent time in a foundry and… Read more

noticed that these were all over so I gave them a try. Couldn't be happier. I fitted it myself. It was slightly smaller than the unit it replaced and took a little messing around to fit it properly and seal up but I believe the hole in the wall had been there for a long time and even the unit that it replaced wasn't fitted well. We use the heat as well as the cool function. It is a lot quieter than the unit it replaced and cycles correctly on the thermostat when the temp is altered. EG turned the heat down when we go to bed and the same when the cool is turned up at the same time. The remote is a little cheap but works as advertised and sets the unit faster than using the onboard controls. We have had this installed for about 12 months now and it hasn't given any trouble at all. Sometimes running for a week non stop. Would gladly purchase again to replace another.

This a/c is terrible on heating. The c5 codes defrosting on cold mornings when you want heat is disappointing. I hope it will cool on a 40 degree day during summer. I hope I don't have to write another review Show details

Does what it's supposed to do. No problems – Purchased from Air-conditioning Warehouse to replace an old (1970's) box A/C. It's installed in a double brick wall and works as intended, being… Read more

somewhat quieter than expected (though still louder than a split system), and copes fine with hot weather (I'm in Adelaide).

Overall it works as expected, no complaints. Doesn't have any fancy functions, just basic settings for temperature, mode etc, but it does the job.

For installation, the machine slides out of its cabinet on a chassis so can install the box first, get that secured, then just put the machinery back in (easily done, it's all on the one tray and just slides back into the cabinet) then clip the front cover back on. Easier than it sounds and it only requires undoing a couple of screws to do that, which is detailed in the manual.

Can also route the cable to come out either side, whichever is preferred.

Tip - set the mode to heat or cool, set the fan speed to auto and temperature as required. This works a lot better in my experience than setting the mode to full auto. Also make sure to point the outlet louvre down for heating, up for cooling, as this improves performance.

Is it powerful enough? – I am actually reviewing the KWH39CRF (identical, except cooling only), so rather than create a new category I'll use this one. To start with, the… Read more

fresh-air vent hole is larger than usual, so that's a plus. Noise is good.

I just don't think it is as cold when set to 16°C as the power output indicates (and yes I'm keeping the drain plug in as the manufacturer recommends to active the splash-cool system). It needs to cool a combined kitchen and dining room. It was a good test today when it was delivered because the outside air was only (a humid) 21°C and inside was 24°C at the start of the test, so I would have expected bone-chilling air from the front of it after a few minutes. A good 40°C day will put it to the test.

In retrospect though, I should have gone for the deeper KWH52CRF which is the maximum for 10 amps.

EDIT 4/3/25: We've had one 40-degree day so far and it is appearing to cope, but takes some time to cool down. With summer now over there is no chance of a 45-degree day to really put it to the test. Nevertheless, I've increased the number of stars to four.

We love the Midea U-shaped AC unit, and find that it stands out for its energy efficiency, quiet operation, and smart app integration, making it… Read more

ideal for homes without central air. Its innovative design allows our window to close while installed, enhancing stability and noise reduction. With a CEER rating of 15, it’s significantly more efficient than standard models and we found it costs under $50/year to run under typical average usage in our home. However, the installation was quite complex and time-consuming, requiring at least two people and careful attention to the manual. The unit’s size and bracket depth (18.5 inches) may pose challenges in tight spaces or near fire escapes.

Pros: Near-silent, energy-saving, app-controlled, cools large areas

Cons: Difficult installation, bulky bracket

Cheap and Effective - but you get what you pay for – I installed this unit in a south facing window of my home office. It has plenty of power for cooling the 18m2 space - even though it's only rated… Read more

for 10m2 - but the room is well insulated and shaded. However, this is no substitute for a split system because of: 1. Noise - although it's not too bad with the fan on low, still substantially louder than a SS 2. On/Off compressor operation - delivers quite cold air when running and fan only when not. I positioned the unit such that it was blowing towards my desk, which delivers an uncomfortable breeze of very cold air when cooling. The direction deflector thingy does nothing much, so I installed a deflector on the outside to send the breeze away from my desk - works a treat.

DO NOT BUY, this unit may seem good but is incredibly prone to excessive mold buildup, by the time you know it you're breathing in huge amounts of… Read more

mold that you cant effectively clean out unlike a regular window unit. This unit only lasted a year before it started leaking water and stopped effectively cooling, I requested a refund from kogan but after wasting 3 whole months of back and fourth emails and even a technician being sent out to assess the unit, I was given no refund. Don't waste your time on this product and just get a regular box window unit because if something goes wrong with this vertical unit you're unlikely to find any guides and instructions on how to fix it or let alone a refund.

What is a window wall air conditioner?

‘Window wall air conditioners’ are often grouped together, as they are similar in two aspects - their boxy design, and the way in which they operate.

Both AC types suction hot air from a room, via an evaporator coil. Hot air is released outside using a condenser coil, as well as vents or an exhaust hose. Some of the air is fed back into the room, passing through the AC condenser and a liquid refrigerant to convert warm air into cool air for you to enjoy.

Wall air conditioners

Different to wall mounted air conditioners, these are also called through-the-wall ACs, as they require a hole to be cut out of a compatible section of your wall. The unit sits flush with an external wall, and any remaining warm air is then transferred outside.

Through-the-wall AC in white

Window air conditioners

The body or steel chassis of a window air conditioner sits predominantly outside, protruding from the window. Vents are located at the back or at the sides of the unit.

What’s the difference between a window and a wall AC?

Apart from the respective spots that they occupy in a room, the main difference between a window and wall AC, practically speaking, is their installation requirements.

Since wall ACs are installed as a fixture into your wall, they are a permanent option. This may make them unsuitable if you’re renting, or you otherwise aren’t able to cut a hole in the wall to house this AC type.

You’ll also need to hire a licensed electrician to install a wall air conditioner, due to its specific requirements. It needs to sit straight and level, and can’t interfere with any existing plumbing or electrical wiring or fixtures. Factor into account installation costs, in addition to the purchase price of a wall AC, which can range from $400-$1,500.

On the other hand, window air conditioners are relatively easy to install, and you may be able to pull off a DIY job with little to no fuss.

Pros and Cons of Window & Wall Air conditioners

Pros
Suitable for spaces up to 50 sqm (such as medium to large bedrooms or home offices)
Reverse cycle functionality is often included, allowing year-round use
More affordable than split system ACs or ducted air conditioning
Don't require hardwiring into an existing electrical system, as many models are designed to run using mains power
Cons
Cooling capacity is less powerful than a split system AC or ducted air conditioning
Running costs may be high, as window and wall ACs are generally less energy efficient than other air conditioners, like split system models
Can be noisy
Cleaning can be fiddly when it comes to maintaining the air filters and removing any condensed water that builds up inside the unit
