How to Use Air Conditioner With Alexa

Controlling your air conditioner with Alexa voice commands is one of the most convenient smart home setups you can have. Say “Alexa, turn on the AC” or “Alexa, set the temperature to 24 degrees” and it happens instantly. Here is how to set it up, whether your AC is a smart unit or a standard one.

Two Ways to Connect Your AC to Alexa

There are two main approaches depending on whether your AC has built-in WiFi:

Smart AC with brand app: Connect via the brand’s Alexa skill for full voice control including mode, temperature, and fan speed.
Any AC with a smart plug: Connect via the smart plug’s Alexa skill for on/off voice control and scheduling.

Method 1: Connect a Smart AC to Alexa

Make sure your AC is connected to your home WiFi via its brand app (Daikin, LG ThinQ, Mitsubishi MELCloud, Midea Air, etc.).
Open the Alexa app on your phone.
Go to More > Skills & Games and search for your AC brand’s skill (e.g., “Daikin”, “LG ThinQ”, “Midea”).
Tap Enable to Use and log in with your brand app account to link the accounts.
Alexa will discover your AC as a device. Go to Devices in the Alexa app to confirm it appears.
You can now control it by voice or through the Alexa app.

Method 2: Connect Any AC to Alexa via Smart Plug

Plug the smart plug into the wall outlet and the AC power cord into the smart plug.
Set up the smart plug using its app and connect it to your 2.4GHz WiFi.
In the Alexa app, go to More > Skills & Games and enable the smart plug’s skill (e.g., “GHome” or “Kasa”).
Alexa discovers the smart plug as a device. Give it a name like “AC” or “Living Room AC”.
Say “Alexa, turn on the AC” or “Alexa, turn off the AC” to control it.

Useful Alexa Voice Commands for AC

“Alexa, turn on the AC”
“Alexa, turn off the AC”
“Alexa, set the AC to 24 degrees” (smart AC only)
“Alexa, set the AC to cool mode” (smart AC only)
“Alexa, what is the AC set to?” (smart AC only)
“Alexa, turn off the AC in 2 hours” (smart plug or smart AC)

Adding the AC to an Alexa Routine

Alexa Routines let you automate your AC as part of a larger sequence. Examples:

Good morning routine: “Alexa, good morning” → turns on the AC, reads the weather, starts your playlist.
Leaving home routine: “Alexa, I’m leaving” → turns off the AC, locks the smart lock, turns off lights.
Time-based routine: AC turns on automatically at 5:30 PM every weekday before you arrive home.

Set up routines in the Alexa app under More > Routines.

Troubleshooting Alexa AC Control

Alexa says device not found: Re-run device discovery in the Alexa app under Devices > + > Add Device.
Skill not linking: Make sure you are using the same account credentials as your brand app.
Commands not working: Check that the device name in Alexa matches what you are saying — rename it to something simple like “AC”.
Smart plug not responding: Check the plug’s WiFi connection in its own app first.

Final Thoughts

Connecting your AC to Alexa takes about 10 minutes and makes everyday climate control effortless. Smart AC units get full voice control over mode and temperature. Any AC gets on/off voice control and scheduling via a smart plug. Either way, you end up with a more convenient and energy-efficient setup.
