Koldfront’s WAC12001W offers 12,000 BTU of cooling capacity. That’s the right size to cool a room of around 500 square feet.
It’s almost as powerful when it comes to heating too. The heater has a capacity of 11,000 BTU.
It mounts straight into your window, and there’s no need for a wall sleeve. You will, though, need a window that’s the right size. This will work with anything between 27 and 36 inches wide, and at least 16 inches high. All the installation hardware and weather seals you’ll need are included in the package.
It’s important to note that this requires a special 230-volt electrical outlet. That might mean you need to get an electrician in.
There’s a choice of three different fan speeds, so you can choose the right balance between power and noise.
An illuminated digital control panel shows your selected temperature. Choose from anything between 62 and 86 degrees Fahrenheit. The electronic thermostat will then heat or cool your room as needed to keep the temperature steady.
There’s a 24-hour programmable timer. This allows you to set the unit to come on and off at pre-set times through the day.
When night falls, you can select the sleep function to save power. This will allow the temperature to rise gradually, before returning to your preferred temperature after six hours.
There’s also the option of a dehumidifier mode. It’s powerful enough to remove 60 pints of moisture from the air each day. If you live somewhere that’s prone to damp or humid weather, that’s a great extra.
All this can be controlled using buttons on the unit, or using the handy remote control. And if you want to change the direction of the air flow, you can. The louvers on the front of the unit can be moved up, down, left and right.
One thing to note, though, is that there’s nothing except a thin filter to block out the outside air. In winter, that means that when the unit stops running, the temperature can fall quickly. Deal with that by covering the front when it’s switched off. Drawing the curtains will help too.
Powerful air conditioner – and almost as powerful as a heater
Electronic thermostat to maintain your desired temperature
24-hour programmable timer and remote control

The thin filter will let cold winter air into your room when the unit isn’t running.
Frigidaire’s model offers 11,000 BTU of heating and cooling power. That makes it suitable for standard height rooms with an area of around 450 square feet.
This is another model that can be controlled using the buttons on the front or with the remote control.
There’s a smart digital display showing the temperature you’ve set. The reading is given in degrees Fahrenheit. The electronic thermostat will adjust the controls as needed to keep the temperature stable.
There’s also a 24-hour timer. Using this, you can program the unit to switch itself on and off at scheduled times throughout the day. If you’re going out, save energy by programming it to come on ten minutes before you return. Your room will be the perfect temperature as soon as you get back.
Maintenance is made easy with an alert that tells you when it’s time to clean the filter. When the light comes on, just slide out the filter out and wash it down.
It’s easy to adjust the direction of the air flow, using the sliding louvers. These can be moved up, down, left and right. There are two sets which can be operated independently of one another to give you maximum flexibility.
Note that this unit is designed to provide what the manufacturers call “supplemental heat”. It won’t be powerful enough to heat a large room on its own. But it’s a great way of topping up the temperature in a cold winter.
Installation is easy. Unlike most units at this level, this requires only a 115-volt energy supply. That means it will work with most standard sockets. And you’ll save on the cost of getting in an electrician to fiddle with your wiring.
The sound levels with this one are moderate. If you’re sensitive to noise, however, you may find it a little loud on the highest fan setting.
Select controls manually or with the remote control

Designed to offer supplemental rather than primary heating
If you’re looking for a unit that will suit a smaller space, check out the WAC8001W from Koldfront. With this one you’ll get a lower cooling capacity of 8,000 BTU. That will effectively cool a room of about 350 square feet.
As with many other combined air conditioners and heat pumps, the heating capacity is lower. In this case it’s considerably lower, at 3500 BTU. That means it’s best thought of as a way to top up the heating in your room.
The design is simple and attractive. The unit is white with buttons on the front. There’s also a sleek remote control. That allows you to choose your chosen temperature and function from the comfort of your seat.
Unfortunately, the remote control isn’t illuminated. If you want to change the settings at night, you’ll need to switch on the light.
Your preferred temperature can be set anywhere between 62 and 86 degrees Fahrenheit. One thing to note, though, is that the unit won’t automatically maintain a pre-set temperature when it’s in heat mode.
There’s an energy saving mode and other features to keep your bills low. An indicator light will tell you when you need to change the filter. And there’s a sleep function which will allow the temperature to rise gradually overnight. After six hours, it will return to your preset temperature.
There’s a choice of three different fan settings. You can also adjust the flow of the air into your room using the louvers. These can be slid to the left, right, up or down to direct warm or cool air where it’s needed.
This unit is designed to work with a 115-volt energy supply. It will fit windows anywhere between 27 and 36 inches wide, and at least 16.5 inches tall. All the hardware needed for installation is included in the package. You’ll also receive weather seals to keep out rainwater.
Range of energy-saving features to keep bills low
Three different fan settings
Louvers can be adjusted four ways to direct the air flow.
The remote control isn’t illuminated
No auto setting to keep the temperature stable in heating mode.
The second model from Frigidaire to make our list, the FFRH0822R1 can be installed in either a window or wall. A window mounting kit is included to help make installation simple.
It offers a cooling capacity of 8,000 BTU, a 7,000 BTU heat pump, and supplemental heating of 3,500 BTU. On the air conditioning setting, it will effectively cool a room of around 350 square feet.
This is another model that comes with its own remote control. There’s a green digital display on the front of the unit that shows you the temperature that’s been set.
There’s also a programmable timer that allows you to schedule when the unit will come on and off. It spans 24 hours in half-hour increments, so it can switch itself on at the same times each day.
It has a dehumidifier setting too. That will efficiently remove around 1.5 pints of excess moisture from the air every hour.
It has a low power start up that conserves energy. For those who prefer to cool their room fast, this may be irritating. It will, though, be good news for your energy bills.
It’s engineered to run quietly, so it’s a good option for bedrooms. On the highest setting, the noise reaches 57 decibels. That’s about the same as the hum of a household refrigerator.
Note that, although there are three fan settings, in heat mode you can only use “low”. The thermostat means that it will turn itself off when it reaches the desired temperature. For those who like the gentle hum to sleep by, you may find that wakes you up.
And as a combined unit, the heat output isn’t as powerful as a standalone heater. In temperatures below 35 degrees Fahrenheit, you’ll want additional heating to keep your room comfortable.
If you’re in an area that suffers from power outages, you’ll be reassured that there’s an auto-restart function. That will restart the unit as soon as the power returns. And it will automatically re-engage the same settings as before the outage.
Maintenance is very easy. An indicator light will come on when it’s time to change the filter. The filter tilts out so it’s easy to access. And it’s covered in a washable mesh that’s simple to clean. That mesh is antibacterial too, so the air will be cleaned as it circulates.
The unit will fit windows between 27 and 36 inches wide, and 16 inches tall. Pleated end panels extend for a snug fit.
Easy to clean
Auto-restart is great for areas that experience regular power outages
The low power start-up is economical but slow
Won’t work effectively as the primary heat source when the outside temperature is below 35 degrees Fahrenheit.
This model from LG has lots in common with the WAC12001W from Koldfront. It has the same 12,000 BTU heating capacity and a similar 11,200 BTU cooling capacity. And like the Koldfront model, it requires a 230-volt power supply – which may mean engaging an electrician.
There is one significant difference, though, and that’s the price. The LG is about 40 per cent more expensive than the Koldfront. So what do you get for your money?
Well, it’s a clean and attractive design. A single set of louvers on the right-hand side allow you to direct the airflow four ways. There’s a green digital display to show the temperature that’s been set. And it can be operated using the buttons on the unit or with the remote control.
There’s a 24-hour programmable timer and a choice of low and high fan speeds. There’s an energy saving function too, to keep your bills under control.
The cooling capacity makes it suitable for a room of around 550 square feet. When in heat mode it will work best for a room of around 450 square feet.
Maintenance is made easy with the LED indicator that lights up when the filter needs to be cleaned. The filter is completely washable, so just slide it out and rinse it off.
The indoor noise varies between 54 and 58 dbA (that’s “A-rated decibels”) depending on whether it’s on high or low. That’s impressively quiet for a machine with this capacity.
And when in dehumidifier mode it will remove an impressive 3.3 pints of moisture from the air every hour.
Note that the refrigerant used here is R410A. That’s not as efficient – or as environmentally friendly – as more modern coolants. But it does the job.
The unit is 23.63 inches wide, 14.97 inches high and 22.06 inches deep. Note that there are no extendable side panels included as standard here.
Installation is easy if you have wooden windows. The case screws to the inside sill.
But if you have aluminum windows, the sill is lower than the bottom of the window. In that case, you’ll have to make a spacer to get it into the right position. If DIY isn’t your strength, you may prefer to get in a handyperson to help.
Overall, one of the pricier models on our list. But with good power, a host of functions and quiet operation, it may be worth the investment.
Powerful at both cooling and heating
Very efficient dehumidifier
Installation isn’t entirely straightforward if you have aluminum windows
The R410A refrigerant used here is less environmentally friendly than some.
This model from LG offers a cooling capacity of 7,500 BTU. It will suit a smaller space of around 320 square feet.
The heating capacity is 3,850 BTU. That puts it firmly in the category of “supplemental heater”. You’ll need another heat source to keep out the chill when the temperature is below 45 degrees Fahrenheit.
In appearance, it’s very similar to the 12,000 BTU model by LG. There’s the same simple and attractive white case, the same digital temperature display, and the same array of LED indicators.
Other features are similar too. You’ll find the same set of louvers on the right-hand side. And like its bigger brother, these can be adjusted up, down, lift and right to direct the air flow.
There are two heating, two cooling and two fan speeds. You can set the temperature to your preferred level, and the thermostat will make sure it stays there. And the 24-hour timer will allow you to program what time it switches on and off every day.
There’s an energy saver function, and an indicator light to tell you when you need to change the filter. There’s a dehumidifier setting too. This won’t suck out quite as much moisture as the larger model, but it’s still effective. You can expect it to remove over two pints of water per hour.
But unlike the 1200 BTU version, you won’t need any high-powered electrics to run this. It works off a standard 115-volt power supply. Installation is generally straightforward, though some people have found attaching the curtain guides tricky.
It does, though, use the same R410A refrigerant. It’s not the most environmentally friendly option out there, but it will cool your room very effectively.
Very effective at cooling smaller spaces
Choice of two heating, two cooling and two fan speeds
The heater isn’t very powerful
The refrigerant isn’t as environmentally friendly as other products.
This Friedrich model looks quite similar to the LG units on this list. There’s the same simple design with the louvers positioned on the right-hand side. There are no buttons on display, giving it a clean appearance. Instead, a digital display in the lower right-hand corner shows the temperature.
But the simple appearance belies a lot of power. This unit offers 23,000 BTU in cooling mode, and 12,000 BTU in heating mode. That makes it a good choice for a large space: it will effectively cool rooms of around 1,400 square feet.
It can be installed in a window or a wall, as best suits your space. And you can choose to run the power cord from either the left or right-hand side of the unit. Standard installation hardware is included in the package.
It’s operated via a remote control. There are no buttons on the unit itself, so make sure you don’t lose it! Use it to set your desired temperature and a thermostat will keep it steady. And there’s a 24-hour timer so you can schedule it to come on and off at the same time daily.
The “money saver” setting is designed to do just what you’d imagine. Select it, and the unit will operate the fan only when it needs to cool the temperature. That will save energy and cut your bills.
When in heater mode, the same setting will cycle the heater on and off every three to four minutes. For some people, that’s a little irritating. It will, though, save you money.
You can direct the air flow four ways with the adjustable louvers. The air filter is washable, and it’s covered in antimicrobial mesh to eliminate germs. And there’s an auto-restart to switch the unit back on after a power outage, retaining the previous settings.
This is a powerful unit, and it’s amazingly quiet. But there are a couple of things to bear in mind.
The first is that the instructions for the heating function could be clearer. The second is that the unit is heavy. That’s not surprising, given how powerful it is. But installation will be much easier if there are two people to help.
Ultra-powerful cooling and heating for spaces of around 1,400 square feet
Money saver mode to cut your bills
Amazingly quiet for such a powerful machine
The instructions for the heating function could be clearer
Heavy – installation will be easier with two people to share the task.
That brings us to the end of our reviews of some of the best window heat pumps out there! Now check out the questions to ask yourself before you go shopping.
What heating and cooling capacity do I need?
The amount of power you need from your window heat pump will depend on the space you’re heating and cooling. Measure your room and calculate the square footage. The larger the area the more capacity – measured in BTUs – you’ll need.
Each of our reviews sets out the square footage to which the unit is suited – but take care. Some factors can mean you need larger capacity – for example, if you have high ceilings.
Add 4,000 BTU if you’re going to be installing your unit in a kitchen. And add 600 BTU for every additional person above two who’ll use the space regularly.
And note that heating capacity will be lower than cooling capacity. In some cases, there’s a big difference. That means you may need to buy an additional heater for the winter.
Think about your bills!
Cooling and heating your home can use a lot of energy, so look for models with energy-saving features.
Keeping your filter clean will help your unit to work efficiently. Look for options that alert you when this needs to be done.
Some models will also have energy-saving modes. They can be called things like “eco” or “money saver”.
Others offer a “sleep” A/C function that allows your room to gradually warm up overnight. Then in the morning, it will kick back in to bring the temperature down again.
Consider noise levels
Not all models are created equal when it comes to noise levels! But this might not matter everywhere. In a kitchen, for example, your priority might be power, and a noisier unit might not matter.
But if you’re installing it in a bedroom, the last thing you’ll want is to have your sleep disturbed. So check out the decibel levels before you buy. Models that offer noise levels in the 55-58 decibel range will be a good bet for a peaceful night’s rest.
Ready to choose?
We hope our reviews have helped you choose the ideal window heat pump for your home. With so many options out there, we know there’ll be one that’s perfect for you.
