The best smart air conditioner in the U-Shaped class comes in the form of the Midea U-Shaped Smart Inverter Window Air Conditioner. The company’s system puts a new spin on a classic design and is also one of the safer air conditioners designed for windows.

U-shaped air conditioners are unique as the parts are housed in two halves connected by a short bridge. This allows homeowners to close their windows to a degree.

As it’s an inverter-based air conditioner, the Midea inverter is not only quiet, but it is extremely efficient.

How to Pick the Best Smart Air Conditioners: Step by Step

Choosing a smart air conditioner isn’t much different than selecting a traditional one. That means you must consider a handful of areas, including the design, capacity, features, and installation.

  • Form Factor
  • Cooling Capacity
  • Installation
  • Features

Form Factor

The term air conditioner can refer to several different types of systems. The first step to finding the best smart air conditioner for your home is to figure out what kind of unit you need. Are you looking for something portable, a seasonal solution, or a system that can do everything?

That basically comes down to a portable or window air conditioner for most homeowners. Portable systems take up floor space, but wheels make moving them around your home easy. They usually come with window kits and are easy to use and set up. They can also have just as much power as their window-based counterparts.

Window air conditioners sit in a window and provide homeowners with ample cooling power. They are affordable and come in a wide range of sizes, but they can be tricky to install depending on the window. Larger units can weigh close to 100 pounds, and they will partially obstruct the view of the window where they’re used.

Cooling Capacity

When shopping for a smart air conditioner, cooling capacity is the first thing to look for once you settle on a style. It’s a metric measure in BTUs or British Thermal Units. The higher the number, the more powerful the air conditioning system. 

While buying a 25,000 BTU air conditioner may seem like a no-brainer, putting it in a 400-square-foot room is a bad idea. It’s a waste of money, although it will keep you chilly compared to an undersized unit struggling to keep a large room cool.

Every reputable manufacturer will provide consumers with BTU and square footing specifications. Choosing the right sized system for a room is critical but easy to figure out. To calculate the size of the area you need to cool, multiply the room’s length by the width.

A 15 x 20-foot room would need a system suited for an area of up to 300 square feet. With that in mind, you also have to consider things like tall ceilings and compensate accordingly. If torn between two sizes, go with the larger smart air conditioner.      


Many homeowners think a portable air conditioner is easier to install than one that sits on a window. Well, that’s not always the case considering they require ventilation. That’s why it’s important to consider the size of the unit along with the style, plus how you plan to vent the system.

Window air conditioners are something most homeowners can install on their own. Ventilation is taken care of once you sit them in the window, but you still need to ensure there’s a good seal in place. Window kits make that relatively simple, although the weight can make installation a hassle.

Portable air conditioners are easier to install in many homes if you can access a window nearby. Placement near a window and power cord can be a big concern, along with condensation. Most units have tanks homeowners can dump, but you still need easy access to a window or you’ll need to make a permanent vent.

You may need to consider the cost of installation with some types of air conditioners.



All smart air conditioners have similar features, including the ones found on regular systems. Speed and modes are common, although it’s rare to find portable or window-based units with more than three speeds. It’s also important to note that some include “auto” as a speed, along with high, medium, and low.

Filters are also common, and most models have a sleep or low-power mode. With portable systems, some models have a heat or humidifying feature. That’s a huge bonus for many homeowners and something rare on window air conditioners. There are more similarities than differences when it comes to intelligent features.

We found that 90% of “smart” air conditioners are compatible with voice assistants from Amazon and Google. The ability to tell Alexa to turn down the air is nice but common in this class, as are mobile apps. Finding a smart air conditioner that works with Apple’s Home Kit is a bit more challenging, however.

What to Know Before Buying a Smart Air Conditioner

Our guide covers the most important aspect of buying a smart conditioner, but there are a few more things to consider if you’re used to homes with central heating and air. Noise will be the biggest surprise to homeowners making the switch, especially if you’re in the room with the unit running.

You may never hear an outdoor HVAC system inside, but portable and window air conditioners can sometimes be quite loud. The best smart AC units won’t sound like a vacuum, but they are noticeable at higher speeds.

We also recommend checking into the installation kit included with these types of air conditioners. That will save a trip to the hardware store, and it’s a good idea to look at pricing and availability for replacement filters. Most are washable, but they don’t last forever. 

Using a Smart Air Conditioner: What It’s Like

The experience of using a smart air conditioner should be pleasant for every homeowner. You can control the system in several ways once the unit is properly installed and set up.

You’ll never have to get off the couch to adjust the temperature. Have a home assistant? If so, you can tell Alexa or Google to set the air conditioner to sleep mode during the night. These brainy devices always come with mobile apps, and the best models are designed with ease of use in mind.
