The Best Window Air Conditioner with Heat of 2020

1. FRIGIDAIRE Window Air Conditioner with Heat

Best Window Air Conditioner with Heat FRIGIDAIRE

View on Amazon

This is a 10,000 BTU air conditioning unit for window installation that can cool a space of up to 500 sq. ft. and possibly more. Furthermore, when the weather turns cold, it also has a heating function that can keep your house warm.

There are a couple of features that we particularly like. It comes with a remote control that can be used to adjust the settings or simply to check the temperature. It also has a 24-hour timer so you can set it to come on or switch off automatically, saving power and money.

One minor negative, however, is that the remote can be a little unresponsive – you may have to push the button a few times to get it to work, although this is hardly a huge problem.

Also, some people might find it a bit on the noisy side. However, while it isn’t the most silent of A/C units, it isn’t excessively loud, and most people probably won’t mind.

All in all, a solid option if you are looking for a reliable air conditioning unit from a respected brand that can cool or warm your home, depending on the season. If that sounds like the kind of thing you need, this could be an option worth considering.

Pros

  • Includes remote control – easy to check or adjust temperature
  • Clean filter alert – tells you when the filter is starting to get clogged
  • 24-hour timer – allows you to program when it switches on and off
  • 8-way air direction – allows you to control where air is blowing
  • Good power – 11,000 BTU and big enough for a 500 sq. ft. space

Cons

  • Remote not the most responsive – sometimes buttons need a few pushes
  • A little noisy – although not excessively so

2. Frigidaire FFRH0822R1 Compact Slide-Out Window Air Conditioner with Heater

Best Window Air Conditioner with Heat FFRH0822R1

View on Amazon

If you like the sound of the Frigidaire unit above but are looking for something a little smaller and more compact, this could be an excellent alternative. It is rated at 8,000 BTU and is designed to cool or heat a room of up to 350 sq. ft.

This unit features several adjustable settings and boasts three fan speeds, three cooling speeds and one heating speed. It is also ENERGY STAR-certified, which means it requires less power to run, costing you less to heat or cool your home.

We also like the fact that it has a built-in dehumidifier, allowing you to remove up to 1.5 pints of moisture per hour from the air.

On the downside, like the larger version, this unit is a little loud, although, for most people, the noise level will be acceptable. Also, the economy mode is not particularly useful since it is not powerful enough to effectively cool a room.

In sum, another solid unit from Frigidaire, this time for people who don’t need to heat or cool such a large space. A reliable air conditioner from an established brand and another possibility that should be worth a look.

Pros

  • Includes dehumidifier – removes up to 1.5 pints per hour
  • ENERGY STAR certified – efficient unit with low power consumption
  • 24-hour timer – allows you to program on and off times
  • Multi-speed operation – set the power to your desired level
  • Includes remote – for adjusting, programming and checking temperature

Cons

  • Economy mode not useful – doesn’t provide enough power
  • On the noisy side – not the most silent option

3. Koldfront WAC12001W Window Air Conditioner with Heat (Our Top Pick)

Best Window Air Conditioner with Heat Koldfront

View on Amazon

For anyone looking for an air conditioner and heater for a larger space, this unit from Koldfront could be worth checking out. At 12,000 BTU when cooling and 11,000 BTU for heating, it is powerful enough to control the temperature in a space of up to 450-550 sq. ft.

With its four operating modes and three fan speeds, it is a versatile unit that will allow you to adapt its use to a range of conditions. We also like the highly effective dehumidifier that can remove up to 60 pints of moisture per day from the air.

Furthermore, it comes with all the installation hardware you need, as well as the necessary window seals, meaning everything you need to fit it is included.

One minor design flaw is that in cold weather, when the heating function is not being used, it lets cold air flow into your home through the filter, and for people in colder areas, this could be a problem. It is also a little noisy, especially when running on full power.

However, other than these minor issues, this is an excellent unit that does a great job of controlling the temperature in larger rooms. It also sells at a very reasonable price point, making it a good option if you insist on getting great bang for your buck.

Pros

  • Large and powerful model – works in spaces of up to 550 sq. ft.
  • Effective humidifier – removes up to 60 pints per day
  • 3 fan speeds – allows you to adjust the operation to your conditions
  • Includes installation hardware and seals – everything you need to fit it
  • Very reasonable price – great value for a high-quality unit

Cons

  • Lets cold air in when not in use – minor design flaw
  • A little noisy – especially when on full power

4. Koldfront WAC25001W Window Air Conditioner with Heat

Best Window Air Conditioner with Heat WAC25001W

View on Amazon

This is another unit from Koldfront, but this time, it’s one that’s designed to heat and cool much larger spaces. When used to lower the temperature, at 25,000 BTU, it is powerful enough for use in spaces of up to 15,000 sq. ft. It can also heat areas of up to 700 sq. ft.

We like the range of different settings it includes. With three fan speeds, four operation modes and four direction louvers, you can set it to just the way you like it. It also includes a remote control, making adjusting it quick and easy.

Another plus is the 24-hour timer that allows you to program when it starts and stops. This means you can then just forget about it and leave it to take care of the temperature in your home – while potentially saving you money on electricity bills at the same time.

The main drawback is the noise it makes since it’s not quiet. However, for such a large and powerful machine, this is what you might expect.

Also, we should point out that in smaller spaces this is simply too big and too powerful, so if you are looking for something to install in a smaller room, this is probably not the best pick.

On the other hand, for cooling or heating larger spaces, this unit is ideal. It is powerful, easy to control and reliable – so if you are looking for a larger unit, this one should feature on your list of possibilities.

Pros

  • 3 fan speeds and 4 operation modes – versatile and adaptable
  • 24-hour timer – can be set to switch on and off at predetermined times
  • Includes remote control – makes it simple and convenient to use
  • Highly effective dehumidifier – removes 137 pints per day
  • Very powerful unit – can cool a space of up to 1,500 sq. ft.

Cons

  • Very loud – although understandable for such a large unit
  • Overkill for smaller spaces – too big and too powerful

5. LG Window Air Conditioner with Heat (Budget Pick)

Best Window Air Conditioner with Heat LG

View on Amazon

At the other end of the scale, if you are looking for a small, compact air conditioner with heating capability for use in a smaller room, this one could be worth a look.

With two cooling speeds, two heating speeds and two fan speeds, it is a highly versatile unit that can be adjusted as required to keep the room temperature just where you want it.

We also like the way this unit runs more quietly than some larger options. If you are the kind of person who finds it difficult to sleep with a loud A/C unit in your bedroom, this could be an ideal solution.

Furthermore, we think this product represents great value for money – it is made by a well-established brand yet costs less than you might imagine. Since it’s so easy to install, you may be able to do it yourself, saving you even more money.

The main downside is that the heating function is not as effective as the cooling mode. If you live in a cold area, this won’t get you through the winter as a primary heater – but as a backup or for those who live in areas with milder climates, it will probably be sufficient.

Other than this, we think this is a good pick for anyone who needs an effective but compact air conditioner that can double as an occasional heater when required. If that’s what you’re looking for, this is a unit that should be on your radar.

Pros

  • Small, compact unit – ideal for smaller homes
  • Versatile unit – 2 cooling speeds, 2 heating speeds and 2 fan speeds
  • Great value for money – very reasonably priced
  • Runs quietly – won’t make too much noise
  • Easy to install – can do it yourself with some basic skills

Con

  • Heating function less effective – although ok as a backup
  • Some water accumulation in the bottom – slight design flaw

Best Window Air Conditioner with Heat Friedrich

View on Amazon

This is an efficient and reliable window air conditioning unit with heating capability from Friedrich. It is notable for its quiet operation, making it a good option for anyone who is sensitive to excessive noise, and it is suitable for spaces up to 350 sq. ft.

Among the positives here are the features it incorporates for improved energy efficiency, including an energy-saving mode. You can also program it to come on and switch off at predetermined times, also helping conserve energy and saving you money.

Like most A/C units, it comes with a remote control for ease of use. We also like the auto-restart feature that keeps your settings if the power goes off, and the washable filter is also a great addition, allowing for simple and inexpensive maintenance.

There few things we don’t like about this unit. We might complain that if you try to change a setting and the remote fails to connect to the unit, it doesn’t tell you, meaning you might think you’ve changed it when, in fact, you haven’t.

Also, it isn’t compatible with smart devices, so you won’t be able to connect with Amazon’s Alexa, for example.

Other than these minor drawbacks, this is an excellent air conditioner. It’s a high-quality unit that represents great value for money, so for anyone looking for a smaller, energy-efficient option, this is one that’s worth considering.

Pros

  • Quiet operation – among the less noisy options available
  • Energy efficient – includes features designed to conserve power
  • 24-hour programming – can choose when it comes on and goes off
  • Auto-air sweep – ensures consistent air distribution
  • Washable filter – for simple, inexpensive maintenance

  • Not compatible with smart devices – some people might find it dated

Best Window Air Conditioner with Heat Keystone

View on Amazon

This A/C unit with heating capability from Keystone is a big, powerful unit designed to cool areas of up to 1000 sq. ft. It is also a highly versatile unit since it is suitable for installation either in a window or through a wall.

We like the way it includes an energy-saving mode and sleep mode to help conserve energy. It also has a 24-hour programmable timer and includes a remote for ease of use.

As well as being able to cool a large area, it can also be used as a backup heater, and it has a powerful dehumidifier that can remove up to 3.8 pints of moisture from the air per hour.

The only real downside is that it’s a little bulky, making it less suitable for smaller homes. Also, it makes a bit more noise than smaller units, but that is understandable and to be expected.

To summarize, this is another solid option that does a good job of cooling large areas and also offers a heating capability. If you are in the market for a larger A/C unit and heater, this one could be another decent option.

Pros

  • Versatile installation – window or through-wall both possible
  • Powerful unit – cools up to 1000 sq. ft.
  • Energy-saving mode – helps reduce electricity bills
  • Sleep mode – also helps conserve energy
  • Effective dehumidifier – removes up to 3.8 pints per hour

Cons

  • Big and bulky – not suitable for smaller homes
