Air conditioning is essential in the summer, but cooling your home can really jack up your energy bill. When I lived in New York City, I’d often bolt out of the house in the morning, forgetting to turn off my window unit. If I had a smart air conditioner, I would have been able to turn it off or enable Energy Saver mode from my desk in the office.
Smart ACs may be more expensive than traditional units, but they can potentially save you money on your energy bill in the long run. Plus they’re just a lot more convenient all around. We’ve rounded up the best smart ACs we’ve tested to help you select the best one for your needs.
To be considered smart, an air conditioner needs to have a Wi-Fi radio so it can connect to an app, allowing you to control and monitor it from your phone or tablet. No matter where you are, smart air conditioners let you do things like adjust the target temperature, change the fan speed, and turn them on and off. Many also let you set a cooling schedule, so they will kick on at a designated time. And some offer support for Amazon Alexa, Apple Siri, and Google Assistant voice commands.
Selecting the Right Size
Before purchasing any air conditioner, it’s important to figure out what size unit you need. If it’s too small, it will have to work harder to reach the target temperature, wasting energy. If it’s too big, it will cool the room before sucking out moisture, leaving you feeling clammy.
recommends increasing capacity by 10 percent if the room is very sunny, reducing it by 10 percent if it’s heavily shaded, adding 600 BTUs if more than two people regularly occupy the room, and increasing capacity by 4,000 BTUs if the unit is located in a kitchen.
When selecting a smart air conditioner, you’ll need to decide whether you want a portable or window unit. Both have their pros and cons. Portable units can be moved from room to room, but they take up floor space, and require a bulky exhaust hose. Window units can be a pain to install and block out your view, but are far more discreet than portable units.

Meanwhile, if you need something to keep you cool without necessarily bringing down the temperature in an entire room, you might want to consider a device like the Evapolar Personal Air Cooler. It’s not an air conditioner, but it keeps you comfortable using evaporative cooling, and it doubles as a humidifier. It’s perfect for hot, dry office buildings.
We test smart air conditioners in our actual homes, taking into account factors like app experience, cooling performance, design and specs, ease of installation, modes, operating volume, and support for voice commands and scheduling. When determining our ratings, we also consider whether a unit is Energy Star certified and/or reports on power usage.
