As with most of the other Kenmore models, this model is also a little more expensive than many people would like to pay. However, all of these features are definitely recommended to every user.

Key Features To Consider When Choosing The Best AC Unit For Smaller Windows

These models are some of the top-rated models on the market today when it comes to smaller windows in your home. However, there is a lot of research that has been done to find these models. If you don’t agree with any of them, we believe this buyer’s guide should give you some insight to understand the different models and help you make the best decision.

Power Output:

As you might have already noticed, the power output is measured the same as many gas heaters. BTU or British Thermal Units refer to the amount of heat being converted. The high this level of power output, the cooler the unit should be able to make your room when you use it. The power output does have a massive effect on the price as well and we generally recommend something in the range of 5,000 BTU.

Room Coverage:

The room coverage is definitely something that you need to keep in mind. Most of these smaller AC units for small windows can cover rooms of up to 150 square feet. As you improve the quality of the AC unit and choose one with a higher power output, you might find a unit that can actually cover a much larger room.

Controls and Price:

As for the control settings, this can be split into three separate groups. The 3 control settings are manual, remote controlled and the smart units. Depending on your budget, you might be able to find the right model. Here is a small breakdown of the control settings that you need to keep in mind with their benefits:

  • Manual: The manual models are self-explanatory. This means you need to physically change the settings on the AC unit when you are close to it. One of the benefits of this model is the price being a little cheaper.
  • Remote Controlled: The remote control is one of the best options. It makes life a little easier for you and you don’t need to pay such an expensive price.
  • Smart Unit: The Smart unit is one of the best options that I have ever used. Many of them can be connected to either the Alexa or Siri operating systems on many mobile devices. This does make life a little easier but also spikes the price of the product significantly.

It is fundamentally important that you know how much the controls or operating system affects the price. I would recommend the remote control for your Ac unit. This is the perfect middle ground when it comes to price and value for your money.


Unfortunately, these models do need to be installed and this can be a little troublesome for many of us. If you have the right mechanical skills and some experience, it should not be that hard for you to actually do it. If not, you might need some expert to assist you in the installation process. You need to look at the price of this endeavor as well.


Since these models are packed with many tech features, it will be in your best interest to have some sort of warranty. The warranties might not be indicated at first and we could not find all of them. However, you can simply call the manufacturer to find the warranty and get the best possible value for your money. Additionally, I always look at the brand reputation and customer support as these devices might need to be serviced from time to time.


These are the top models we have tested and used; now it is your turn to let us know which models you actually prefer for your home. Let us know in the comment section how the models have affected you and if you have used them. I would personally recommend Kenmore as the number one brand that offers some of the best value for money.
