Alexa, Make My Room Cooler!

WWith Memorial Day coming up and temps already rising here in Massachusetts, I figured it was high time to update this blog post on the best smart window air conditioners.

Last year, I added a smart AC in the bedroom. This year, I’m adding a second one in my living room, expecting the same boost in comfort and energy savings.

Smart ACs now offer Amazon Alexa and Google Assistant support, multiple fan speeds, and coverage for everything from small bedrooms to large living spaces. With Energy Star ratings and smarter controls, they use less power and can help lower your electric bill—just in time for summer.

Perhaps this is why, according to Verified Market Research, the smart window air conditioners market is expected to reach $43.59 billion by 2030, growing at a 14.5% CAGR.

While I couldn’t afford to buy all five units on my list, I tested two and thoroughly researched the rest—so I stand by these picks.

A few smart features can turn a standard AC into the best smart window air conditioner for your needs!  Next, I’ll get into some mini reviews for all five of my picks along with the key specifications and pros and cons of each.

What Size AC Unit Do You Need?

When it comes to choosing the size of a smart WiFi window air conditioner, the carpenter’s golden rule holds true. Measure twice, cut once!

As a general guide for a small room, you want 8,000-10,000 BTU, for a medium-sized room: 10,000-12,000 BTU, and for larger rooms: 12,000-15,000. For a chart with specific room size square footage see below.

Here’s a quick chart that maps BTU to room sizes for the most popular window models:

Oh, and of course, the window unit will need to fit the window into which you want it installed!  Again, you should carefully measure as all of the units vary in shape and size. Installation hardware is generally not included so you may need to purchase a kit to secure the unit (or maybe just a piece of plywood), depending on your home.

 Are u-shaped units better than traditional window ACs or portable ACs?

U-shaped units offer a unique design that allows the window to close more tightly, reducing noise and improving energy savings.
