How To Make A Dumb Air Conditioner Smart
Especially for those of us in New England, the summer season comes and goes so fast. However, when the weather gets hot, sitting around in a hot house or apartment is no fun at all.
I like to keep things nice and cold all summer long. Nerd alert: my 25-year-old son Chris and I like to joke around that we like things “data center cold.” This is even truer during those hot summer nights.
But running your air conditioner-especially an older dumb air conditioner-all summer can be super expensive, according to the U.S. Department of Energy. And the experts at HVAC.com agree: older cooling systems can drive up your energy consumption fast.
But you and I don’t need experts to tell us. Even though I have electric heat, my “cooling” bill used to be nearly as much in the summer as my heating bill in the winter. Yikes!
That is, until last year.
What did I do? I implemented two of the four methods I will cover in this post on how to make your dumb air conditioner smart. Since then, my energy bills in the summer are nearly half of what I was paying before. Very cool.

Method #1: Use a Smart AC Controller
If you want the best way to make your dumb air conditioner smart, a smart AC controller is the simplest and most cost-effective solution. These clever smart devices use infrared remote control signals to communicate with your existing dumb air conditioner, turning it into a true smart appliance with Wi-Fi, app, and voice control capabilities.
✔ Control Any Dumb AC from Your Smartphone
Smart AC controllers work via a smartphone app, allowing you to monitor and adjust your current temperature, mode (like cool mode), and humidity level remotely-even while you’re stuck in traffic or out grabbing a coffee.
You can also control multiple smart ACs throughout your smart home using global controls, from your living room to the guest bedroom.
✔ Cut Energy Bills with Smart Scheduling
You can schedule your AC to run at optimal times of the day using weekly schedules. Many models also include geolocation support, so the unit shuts off when you leave and turns on when you return. The result? Real energy savings and reduced energy consumption.
✔ Full Voice Assistant Integration
These controllers are compatible with Amazon Alexa, Google Assistant, Google Home, and Siri. Simple voice commands like “Turn on the AC in the living room” or “Set the temperature to 72” are all you need to stay cool.
🏆 Top Pick: Sensibo Sky at Amazon
I’ve used the Sensibo Sky since last year, and it has already paid for itself-several times over.
Simply plug in your Sensibo Sky, connect to WiFi, launch the app, and enjoy a smarter, connected environment. Sensibo Sky connects with all remote controlled AC units.
Looking for alternatives? You can also consider Cielo Breez, Tado, or Ambi, but Sensibo Sky remains the most reliable in my experience.

Method #2: Upgrade to a Smart Air Conditioner
Sometimes the only option is to replace your old window air conditioner with a fully integrated smart air conditioner. These units come packed with smart features, native app support, and often outperform older models in cooling power and efficiency.
🏆 Top Pick: LG 12,000 BTU Smart AC with Heat at Amazon
Smart Features Built Right In:
- Built-in Wi-Fi and LG ThinQ app control
- Compatible with Amazon Alexa and Hey Google
- Supplemental heating and cooling modes
- Works well in rooms up to 550 sq. ft.
- Auto-restart and filter change alerts
- Energy-efficient and relatively quiet (54 dB)
💡 Many modern window units and portable air conditioners now support native voice assistant functionality and require only a standard electrical outlet.
📌 Note: Portable ACs must be properly vented. This trips up many buyers, so check compatibility with your window space before ordering.
LG ThinQ Technology lets you control your LG window air conditioner from anywhere
Method #3: Install a Smart Thermostat (for Central Air)
If your home has central air, the most elegant way to make your dumb air conditioner smart is by installing a smart thermostat. This is the ideal upgrade for whole-home systems.
🏆 Top Pick: Nest Learning Thermostat at Amazon
Smart Thermostat Benefits:
- Controls both air conditioning and heating
- Uses sensors and AI to “learn” your habits
- Integrates with smart switches, IFTTT, and voice assistants
- Allows for smart energy savings with automated weekly schedules
Models like the Nest Learning Thermostat and Ecobee 4 are top-rated. Personally, I plan to make the switch to Nest myself. Even if you’re colorblind like me, the interface is sharp and easy to read.
Easy control in the Google Home app on your phone from anywhere or by using your voice with Alexa, Siri, or Google Assistant smart speaker.
Method #4: Use a Smart Plug (With Caution)
It’s possible to use a smart plug to make your dumb air conditioner smart, but only under the right conditions-and never blindly.
🏆 Top Pick: Amazon Smart Plug
When It’s (Maybe) Safe:
- Your AC must have a mechanical power button that defaults to ON
- The plug must match or exceed your unit’s power rating
- Your electrical outlet must support the draw safely
When It’s Not:
- You’re running a large, high-wattage window AC unit
- You’re using an unknown or off-brand smart plug
- You’re unsure of your appliance’s wattage or circuit rating
Amazon Smart Plug works with Alexa to add voice control to any outlet.
Based on my own experience (including one that fried a Christmas tree), I only recommend this option for confident users. If you do go this route, please consult an electrician and stick with a quality smart AC plug like the Amazon model linked above.
