Quick Pick: Best window ac unit with heat
Best window ac unit with heater
1. Koldfront WAC8001W Window Air Conditioner with Heater and Remote
Koldfront are industry leaders in air conditioners with heaters, and a number of their models make our list.
The WAC8001W combines an 8,000 BTU (British Thermal Units) air conditioner with 3,500 BTU of heating. The air conditioner will easily cool down a space of up to 3,500 square feet. And while the heater isn’t powerful enough to act as a primary heat source for your room, it’s great to make things a bit cosier.
Three fan speeds allow you to adjust the strength of either cooling or heating. And there’s a remote control, so you won’t even have to leave your seat to do it. There’s also a touch panel and an easy-to-read digital display on the unit itself.
Some people find the fan is a little noisy, though, especially on the highest setting.
Like all the models on our list, it can be installed in a window so it won’t take up floor space. The window needs to be between 26 7/8 inches and 36 inches wide. And it must be at least 16 ½ inches high. The unit works on an input voltage of 115 Volts or 60 Hertz.
It comes with all the hardware and weather seals you need for installation. And there’s a 2-year warranty for peace of mind. Maintenance is made easier with washable air filters.
Pros:
- Choice of three fan settings
- Remote control and on-unit controls
- Washable air filters for easy maintenance
Cons:
- The heater isn’t the most powerful – this isn’t designed to be the main source of heat in your room
- Some people find the fan a bit noisy, especially on the highest setting
2. Soleus Air 10,000 BTU Window Air Conditioner with HEAT
This model from Soleus Air combines no fewer than four different functions – air conditioning, heating, dehumidifier and fan.
The innovative design is shaped like a saddle that fits over your windowsill. That makes installation super-easy, with no tools required. For it to fit, you’ll need a maximum window sill clearance of 12.5 inches. Your window will need to be 24 to 48 inches wide, with a minimum height clearance of 16 inches.
The design also means that the unit won’t get in the way of the view outside.
But what about the temperature control? Well, this is a powerful model, offering a combined 10,000 BTU of heating and cooling. But the saddle design keeps the compressor outside your property, meaning it’s quieter than it would otherwise be.
Soleus Air claim it’s “whisper quiet” but not everyone agrees. If the fan is on, noise levels rise significantly.
You can keep the fan on low by selecting the “sleep” setting. This will also turn off the lights on the temperature display.
Choose the auto mode, and the unit will automatically switch from cooling to heating, depending on the room temperature.
Watch out for unusual choices though! The thermostat inside the unit can be tricked into believing the room is cooler than it is by the proximity of the cold condenser coils. So it can sometimes turn the heater on when it’s not needed.
The good news is that there’s also a “MyTemp” remote control. That resolves the problem by effectively turning the remote control into a roving thermostat. And if you carry the remote control around with you, it will keep the temperature steady wherever you are in the room.
Pros:
- 10,000 BTU combined cooling and heating power
- The saddle design works brilliantly with sash windows and won’t obscure your view
- MyTemp remote control allows you to keep the temperature steady wherever you are in the room
Cons:
- The in-unit thermostat is rather unreliable – watch out for the heating being switched on unnecessarily
- It’s not really “whisper quiet”
3. Koldfront WTC12001W Heat and Cool Air Conditioner
The second model from Koldfront to make our list, the WTC12001W offers 12,000 BTU of air conditioning power. For heating, there’s a powerful 10,600 BTU. It’s suitable for rooms with an area of up to 550 square feet.
It has a combined energy efficiency rate of 9.5. If you’re going to be using it all year, you can expect it to add about $123 to your energy bills.
It comes with four-way directional louvers, so you can direct the warm or cool air where you want it. There are three different fan speeds and four modes: cool, heat, dehumidify and fan only (to remove stale air).
There’s also an energy saving mode and 24-hour timer. There’s a remote control so you can adjust the settings without leaving your seat. And there’s a digital display on the unit, plus buttons you can use if the remote’s slipped down the back of the sofa.
The display is a little small though, and the pale gray buttons on the remote aren’t the best if you don’t have perfect vision.
You’ll need a steel through-the-wall sleeve to install the unit in your window. That needs to be purchased separately.
Pros:
- Choice of four different modes: aircon, heating, dehumidifier and fan-only
- Energy saving mode and 24 hour timer
- Comes with remote control for easy adjustment
Cons:
- The pale gray buttons on the remote look classy but can be hard to read in dim light
- You’ll need to buy a through-the-wall sleeve separately to install it
4. Koldfront WAC10003WCO Window Air Conditioner with Dehumidifier and Remote Control (Our Top Pick)
The WAC10003WCO from Koldfront is a mid-range option in terms of power. It offers 10,000 BTU and is suitable for rooms with an area of up to 450 square feet.
The air conditioner uses the super-efficient R32 coolant, which makes it very cost-effective to run. It also comes with an energy saver mode and a 24 hour timer for maximum efficiency.
There’s also an auto function, which will switch on the fan or heater to keep the temperature where you want it. A sleep mode turns down the fan for quiet operation. And a dry mode turns the unit into a dehumidifier. (Note though, that there’s no way to set a percentage humidity.)
Select your chosen mode and temperature using the remote control. There’s a control panel on the unit too. The louvers on the front can be adjusted four ways to allow you to direct the airflow. And there’s a choice of three different fan settings.
For some people, though, the fan is rather loud. That’s especially the case on the highest setting.
The unit measures 14.6 inches high, 19 inches wide and 21.4 inches deep. It will fit windows between 23 and 36 inches wide, and at least 15.5 inches tall. And unlike some of the Koldfront models, you won’t need a steel sleeve to install it.
Pros:
- Uses R32 coolant, so it’s very efficient
- Has an energy saver mode and 24 hour timer
- Choice of four modes and three fan settings
Cons:
- Some people find it a bit loud, especially when the fan is on the highest setting
- The dry mode isn’t as sophisticated as a standalone dehumidifier
5. Keystone KSTHW12A Window AC Unit with Heat
This powerful model from Keystone offers 12,000 BTU air conditioning, and 11,000 BTU heating. That makes it suitable for rooms up to 550 square feet.
As with most combined units, though, the heater is still designed to supplement another heat source. It’s unlikely to heat the space enough on its own and works best when outdoor temperatures are above 45 degrees Fahrenheit.
It has three fan settings, though note that there’s only one setting for the heater. There’s a dry mode too, which acts as a dehumidifier. That will remove 2.5 pints of moisture from the air every hour.
There’s also an energy saver mode, a sleep mode, and a programmable 24-hour timer. You can select the settings on the unit, which also includes a digital display.
A minor gripe is that the display switches off until you press a button again. That saves energy but means you can’t see the temperature and setting at a glance.
There’s a remote control, which also operates as a remote thermostat. That enables you to set the unit to keep the temperature steady wherever the remote control is. So if you want to stay at the perfect temperature, just keep the remote control with you.
Louvers on the front of the unit can be adjusted in four directions. That allows you to control the airflow into the room.
Note that this needs a special 230-volt/ 25-amp electrical outlet. When that’s in place, though, the rest of the installation is simple enough. And the chassis of the unit can be removed to make the whole process easier.
Pros:
- Comes with energy saver, sleep mode and 24 hour timer
- Three fan settings for cooling and one for heating
- Remote control will maintain your chosen temperature wherever you are in the room
Cons:
- Needs a 230-volt outlet for installation
- The digital display switches off until you press a button again
6. LG LW1816HR Heat and Cool Window Air Conditioner
If you have a larger room where you want to control the temperature, check out this combined air conditioner and heater from LG. With 18,000 BTU, it will work for rooms up to 1,000 square feet.
It has just two fan speeds, but both can be used in either heating or cooling modes. There’s also an energy saving mode and a programmable timer. An LED switches on to tell you when the filters need to be cleaned.
It’s easy to control using either the buttons on the unit or the remote control. And if a power failure causes it to shut down, it will restart automatically when the power returns.
There aren’t quite as many bells and whistles here as with some other models. There’s no sleep mode, for example. But it’s competitively priced and does what it’s supposed to.
Pros:
- Powerful enough for rooms up to 10,000 square feet
- Energy saving mode and programmable timer
- Fan settings can be used for both cooling and heating but …
Cons:
- … there are only two of them
- It doesn’t have a sleep mode
7. PerfectAire 3PACH18000 Window Air Conditioner with Electric Heater
This unit from PerfectAire is another that offers plenty of power. It has 18,500 BTU cooling capacity and 16,000 BTU heating capacity. And that makes it suitable for rooms with an area of between 700 and 1,000 square feet.
The high power rating means this is another case where you’ll need a special electrical outlet. It needs to be 230 volts, not the standard 115. Once in place, the unit can provide room temperatures of between 62 and 86 degrees Fahrenheit.
It includes auto, sleep, dry and energy saver modes. There are directional louvers too, although note that these can be moved only from side to side.
There are electronic controls on the unit, and a remote control to make life easier. The remote control has a “follow me” function too, so you can keep the temperature constant wherever you are in the room.
Tilt out filter access makes maintenance easier. And the unit comes with all the fixings and full instructions for installing it in your window.
Pros:
- Powerful enough for rooms between 700 and 1,000 square feet
- Includes remote control with “follow me” function to maintain the right temperature wherever you are in the room
- Auto, sleep, dry and energy saver modes
Cons:
- The louvers can only be adjusted from side to side to direct the airflow
- Needs a 230-volt electrical outlet
