Not all LG air conditioners come with built-in WiFi capabilities. Before you begin, confirm that your model is compatible with the LG ThinQ platform. Here’s how:

Look for the ThinQ Logo

Check the front panel, remote control, or user manual for the “LG ThinQ” logo. Most smart-enabled LG ACs from 2020 onward include this branding.

Check the Model Number

Visit the LG official website and enter your model number in the support section. Look for features like “WiFi Connect,” “Smart Diagnosis,” or “ThinQ Compatible.” Popular 2026 models with WiFi include:

• LG Dual Inverter Window AC (LW1824HRSM)
• LG Smart Portable AC (LP1424WNR)
• LG Art Cool Mirror Inverter (S32ETW)

Verify Remote Control Features

Smart LG ACs often come with a remote that has a “WiFi” or “Connect” button. If your remote lacks this, your unit may not support WiFi.

Tip: If your AC doesn’t have built-in WiFi, consider purchasing an LG WiFi module (sold separately for select models). Check compatibility on LG’s website.

Practical note: In practice, the quickest way to verify compatibility is scanning the QR code on the unit’s rating plate with the LG ThinQ app itself — it will instantly confirm support and pull up the correct setup flow.

Step 2: Download and Set Up the LG ThinQ App

The LG ThinQ app is your command center for all smart LG appliances, including air conditioners. It’s available for free on both iOS and Android.

Download the App

Go to the Apple App Store or Google Play Store and search for “LG ThinQ.” Download and install the app. As of 2026, the app supports over 50 LG appliance types and receives regular updates for improved performance.

Create an LG Account

Open the app and tap “Sign Up” to create a free LG account. You’ll need:

• A valid email address
• A secure password
• Your country and preferred language

Note: Use the same account across all LG smart devices for seamless integration.

Log In and Prepare for Setup

Once logged in, tap the “+” icon in the app to add a new device. Select “Air Conditioner” from the list. The app will guide you through the connection process.

Pro tip: Enable automatic app updates on your phone so you always have the latest ThinQ features — LG pushes meaningful improvements (like refined geofencing logic) several times a year.

Step 3: Connect Your LG AC to WiFi

Now it’s time to link your air conditioner to your home WiFi network. Follow these steps carefully.

Ensure Your AC Is Powered On

Plug in your LG air conditioner and turn it on using the remote or power button. The unit must be in standby mode (not actively cooling) during setup.

Put the AC in WiFi Pairing Mode

Press and hold the “WiFi” or “Connect” button on the remote for 3–5 seconds. You’ll see the WiFi indicator light on the AC unit blink rapidly. This means it’s ready to connect.

If your remote doesn’t have a WiFi button, press and hold the “Filter” and “Temp Down” buttons simultaneously for 3 seconds.

Connect via the LG ThinQ App

1. In the app, tap “Add Device” and select “Air Conditioner.”
2. Choose “WiFi Setup” and follow the on-screen prompts.
3. The app will search for nearby LG devices. Select your AC when it appears.
4. Enter your home WiFi network name (SSID) and password.
5. Make sure your phone is connected to the same 2.4GHz network (not 5GHz).

Important: Most LG ACs only support 2.4GHz WiFi. If your router broadcasts both 2.4GHz and 5GHz under the same name, temporarily rename the 5GHz network or disable it during setup.

Wait for Confirmation

The app will send the WiFi credentials to your AC. This may take 1–2 minutes. Once connected, the WiFi light on the unit will stay solid, and the app will confirm success.

Router-side tip: Reserve a DHCP address for the AC’s MAC address in your router settings — this prevents IP conflicts after power outages and keeps the ThinQ connection stable long-term. For more on network considerations during HVAC installs, see our split AC installation guide.

Step 4: Name and Organize Your AC in the App

After connection, personalize your device for easier control.

Assign a Name

Tap on your AC in the app and select “Edit Name.” Use something descriptive like “Living Room AC” or “Master Bedroom Cooler.”

Set a Room Location

Assign the AC to a room (e.g., “Kitchen,” “Guest Room”) so you can control multiple LG devices by location.

Enable Notifications

Turn on alerts for filter changes, maintenance reminders, or power outages. This helps keep your AC running efficiently.

Organization hack: If you manage multiple units across a rental property or large home, prefix names with a property code (e.g., “A1-Living Room”) — voice assistants then disambiguate cleanly: “Alexa, turn on A1 Living Room AC.”

Step 5: Control Your AC Remotely Using the App

Once connected, you can control your LG air conditioner from anywhere with an internet connection.

Basic Controls

From the app home screen, tap your AC to access:

• Power on/off
• Temperature adjustment (in 1°F or 1°C increments)
• Fan speed (Low, Medium, High, Auto)
• Mode selection (Cool, Heat, Fan, Dry, Auto)

Advanced Features

Explore these smart functions:

• Schedule Timer: Set your AC to turn on or off at specific times (e.g., cool the house at 5 PM before you arrive).
• Away Mode: Automatically adjusts temperature when you’re not home to save energy.
• AI Cool: Uses sensors and usage patterns to optimize cooling and reduce power consumption.
• Energy Monitoring: View daily, weekly, and monthly energy usage to track efficiency.

Example: Set a schedule to cool your bedroom to 72°F at 10 PM every night. The app will send a notification when the AC turns on.

Energy insight: The energy monitoring dashboard breaks down consumption by mode — use it to spot if “Fan Only” runs longer than needed. Pair those findings with our recommendations on the best air conditioning settings for energy efficiency to fine-tune schedules.

Step 6: Set Up Voice Control with Alexa or Google Assistant

Take convenience to the next level by controlling your AC with your voice.

Link LG ThinQ to Alexa

1. Open the Amazon Alexa app.
2. Tap “More” > “Skills & Games.”
3. Search for “LG ThinQ” and enable the skill.
4. Log in with your LG account credentials.
5. Discover devices—Alexa will find your AC.

Now say:

• “Alexa, turn on the Living Room AC.”
• “Alexa, set the temperature to 70 degrees.”
• “Alexa, what’s the temperature in the bedroom?”

Link LG ThinQ to Google Assistant

1. Open the Google Home app.
2. Tap “+” > “Set up device” > “Works with Google.”
3. Search for “LG ThinQ” and link your account.
4. Authorize access and sync devices.

Now say:

• “Hey Google, turn off the AC.”
• “Hey Google, cool the living room to 68 degrees.”
• “Hey Google, is the air conditioner on?”

Tip: Use voice commands to adjust settings without touching your phone—perfect for when you’re cooking or relaxing.

Voice nuance: Both assistants respond best when you use the exact room + device name you set in Step 4. If you rename a device later, re-run device discovery in the Alexa/Google Home app — a common oversight that causes “device not found” errors.

Step 7: Use Smart Modes for Energy Efficiency

LG’s smart modes help reduce energy use while maintaining comfort.

AI Cool Mode

This feature uses built-in sensors to detect room temperature, humidity, and occupancy. It automatically adjusts cooling intensity and fan speed. In 2026, AI Cool has improved with machine learning, adapting to your habits over time.

Example: If you usually lower the temperature at 8 PM, AI Cool will start cooling earlier to reach your preferred temp on time.

Away Mode

Enable this when you’re traveling. The AC will maintain a moderate temperature (e.g., 80°F in summer) to prevent extreme heat or humidity, saving up to 30% on energy.

Sleep Mode

Gradually increases temperature by 1–2°F per hour while you sleep, reducing energy use and improving comfort.

Geofencing (Location-Based Control)

The app can detect when you’re leaving or approaching home using your phone’s GPS. It can automatically turn the AC off when you leave and start cooling when you’re 10 minutes away.

Note: Enable location permissions for the LG ThinQ app to use geofencing.

Real-world observation: Geofencing radius defaults to ~500 m; in dense urban areas with tall buildings, GPS drift can trigger early/late actions. A practical workaround is pairing geofencing with a fixed schedule as a fallback — the schedule ensures baseline comfort even if location services hiccup.

Step 8: Update Firmware for Optimal Performance

LG regularly releases firmware updates to improve connectivity, add features, and fix bugs.

Check for Updates

1. Open the LG ThinQ app.
2. Tap your AC > “Settings” > “Firmware Update.”
3. If an update is available, tap “Download and Install.”

The AC must be connected to WiFi and powered on during the update. Do not unplug it.

Enable Auto-Update (Recommended)

Turn on “Automatic Updates” in the app settings to ensure your AC always has the latest software.

Update hygiene: Schedule a monthly “firmware check” calendar reminder — auto-update occasionally stalls if the AC loses WiFi mid-download. A manual check catches those edge cases.

Troubleshooting Common WiFi Issues

Even with perfect setup, you might face connection problems. Here’s how to fix them.

AC Not Connecting to WiFi

• Ensure your router is within 30 feet of the AC.
• Confirm you’re using a 2.4GHz network (not 5GHz).
• Restart your router and AC.
• Reset the AC’s WiFi module: Press and hold the “WiFi” button for 10 seconds until the light blinks rapidly.

App Can’t Find the AC

• Make sure your phone and AC are on the same WiFi network.
• Turn off mobile data on your phone during setup.
• Reinstall the LG ThinQ app and try again.

Intermittent Disconnections

• Check for WiFi interference from microwaves, cordless phones, or thick walls.
• Move the router closer or use a WiFi extender.
• Update your router’s firmware.

Voice Commands Not Working

• Re-link the LG ThinQ skill in Alexa or Google Home.
• Say the exact device name you set in the app.
• Ensure your smart speaker is online and updated.

App Crashes or Freezes

• Close and reopen the app.
• Update the app from the App Store or Play Store.
• Restart your phone.

Pro Tip: If all else fails, perform a factory reset on the AC (see user manual) and reconnect from scratch.

Escalation path: When the AC connects to WiFi but won’t cool, the issue is often refrigerant charge or a stuck reversing valve — not the network. Our troubleshoot AC blowing warm air guide walks through those mechanical diagnostics step by step.

Security and Privacy Tips

Your smart AC collects data to improve performance, but it’s important to protect your privacy.

Use Strong Passwords

Create a unique password for your LG account and WiFi network. Avoid common phrases.

Enable Two-Factor Authentication

In the LG ThinQ app, go to “Account Settings” > “Security” and turn on 2FA for extra protection.

Review App Permissions

Only allow necessary permissions (location, notifications) and disable unused ones.

Log Out on Shared Devices

If using a family tablet or public device, always log out of the app when done.

Network segmentation: For stronger isolation, place all IoT devices (including the AC) on a dedicated VLAN or guest network — this limits lateral movement if any device is compromised. The FCC’s IoT security guidance outlines this approach for home networks.

Comparison: LG ThinQ vs. Other Brand Smart AC Platforms

Quick take: ThinQ leads on auto-update reliability and voice ecosystem breadth; SmartThings wins if you already own Samsung appliances; Daikin/Mitsubishi offer better local-control fallback for privacy-focused users.
