Before you begin, make sure you have everything ready. A smooth setup starts with preparation.
Gather Your Tools and Equipment
Your LG ThinQ air conditioner (window or split type)
Smartphone or tablet with iOS 16+ or Android 12+
Stable Wi-Fi network (2.4 GHz band recommended)
LG ThinQ app (download from App Store or Google Play)
Power outlet near the installation site
User manual (for model-specific details)
Check Your Wi-Fi Network
LG ThinQ devices work best on a 2.4 GHz Wi-Fi network. Most modern routers broadcast both 2.4 GHz and 5 GHz bands. Make sure your phone is connected to the 2.4 GHz network during setup. If your router uses a combined network name (SSID), you may need to temporarily separate the bands in your router settings. For more on this, see our guide on are air conditioner brackets required in nyc.
Tip: If you’re unsure, check your router’s admin panel or contact your internet provider. A strong signal near the AC unit is essential—avoid placing the AC behind thick walls or metal objects.
Router Configuration Tips for 2.4 GHz
If your router uses a single SSID for both bands, log into the admin interface and create a dedicated 2.4 GHz network (e.g., “Home_2.4”). Assign a unique password and ensure the channel is set to 1, 6, or 11 for minimal interference. Place the router within 30 ft of the AC unit with a clear line of sight. In practice, a dedicated 2.4 GHz SSID prevents the AC from accidentally hopping to 5 GHz and dropping the connection.
Download the LG ThinQ App
The LG ThinQ app is your command center. It’s available for free on the Apple App Store and Google Play Store. Search for “LG ThinQ” and download the official app. As of 2026, the app has been redesigned with a cleaner interface, faster loading, and improved AI suggestions.
Once installed, open the app and create an account if you don’t already have one. Use a valid email and strong password. You can also sign in with Google or Apple ID for faster access.

Step-by-Step Setup Process
Now that you’re prepared, let’s begin the setup. Follow these steps in order for the best results.
Step 1: Install the Air Conditioner
If you haven’t already installed your LG ThinQ AC, do that first. This guide assumes basic installation is complete. For window units, ensure the unit is securely mounted and the exhaust hose is properly connected. For split systems, the indoor and outdoor units should be installed by a professional.
Important: Never plug in the AC until the setup is ready. This prevents accidental power surges during configuration.
For detailed split‑system mounting steps, refer to our split AC installation guide.
Step 2: Power On the Unit
Plug in your air conditioner and press the power button on the unit or remote. The display should light up. You may see a welcome message or a blinking Wi-Fi icon—this means the unit is ready to connect.
Wait about 30 seconds for the system to initialize. The fan may run briefly as part of the startup check.
Step 3: Open the LG ThinQ App
Launch the LG ThinQ app on your phone. Tap the “+” icon or “Add Device” button. The app will scan for nearby LG devices.
Make sure Bluetooth is enabled on your phone—this helps the app detect the AC during pairing. If the app doesn’t find your unit, tap “Manual Setup” and select “Air Conditioner” from the list.
Step 4: Connect to Wi-Fi
The app will prompt you to select your Wi-Fi network. Choose your 2.4 GHz network and enter the password. Double-check for typos—Wi-Fi errors are the most common setup issue.
Once connected, the app will send network credentials to the AC. This may take 30–60 seconds. You’ll see a progress bar and a confirmation message when successful.
Tip: If the connection fails, try moving your phone closer to the AC or restarting your router. Some users in 2026 reported better results by temporarily disabling 5 GHz bands during setup.
Step 5: Name Your Device
Give your air conditioner a name, like “Living Room AC” or “Bedroom Cooler.” This helps when you have multiple LG devices. You can change the name later in the app settings.
The app may also ask you to select the room where the AC is located. This helps with automation and energy tracking.
Step 6: Complete the Setup Wizard
The app will guide you through a few final steps:
Confirm the AC model and firmware version
Enable location services (optional, for weather-based cooling)
Opt into usage analytics (helps LG improve features)
Set up energy-saving preferences
Tap “Finish” when done. Your AC is now connected and ready to use!
After finishing, check for a firmware update in the app settings to ensure you have the latest performance improvements.
