Tips for Maximizing Efficiency and Comfort
Smart control isn’t just convenient—it’s eco-friendly and cost-effective.
Use Eco Mode
Enable Eco Mode in the app to reduce energy use. The AC will adjust fan speed and temperature to save power without sacrificing comfort.
Set a Comfortable Temperature
The Department of Energy recommends 78°F when you’re home and higher when away. Use the app to automate this.
Avoid Extreme Settings
Setting the AC to 60°F won’t cool your home faster—it just wastes energy. Let the system work at its designed pace.
Use Fans with Your AC
Ceiling or floor fans help circulate cool air, allowing you to raise the thermostat by 4°F without noticing a difference.
Seal Windows and Doors
Prevent cool air from escaping. Use weather stripping or caulk to seal gaps.
Advanced Automation with Scenes and Routines
You can group your LG AC with other ThinQ devices—lights, sensors, or smart plugs—into scenes that activate with a single tap or voice command. For example, a “Movie Night” scene could lower the temperature, dim the lights, and close the blinds automatically. The app’s routine builder lets you set triggers based on time, device state, or geofence events, giving you a truly hands‑free climate experience. For more ideas on seasonal upkeep, see our seasonal upkeep guide.
Multi‑Unit Management for Whole‑Home Comfort
If you have several LG units, the ThinQ dashboard shows each one on a single screen so you can compare runtime, filter status, and energy use side by side. Naming each unit by room (e.g., “Living Room AC”, “Bedroom AC”) keeps the view tidy and makes voice commands unambiguous. When planning a whole‑home upgrade, our guide on choosing the right unit can help you match capacity to each space.
Security, Privacy, and Firmware Best Practices
LG encrypts communication between the AC and the ThinQ cloud, but you should still protect your home network: use WPA3 or at least WPA2‑AES, disable WPS, and keep the router firmware current. The app notifies you when a new AC firmware release is available; install it promptly to patch vulnerabilities and unlock features. For details on the platform’s security model, refer to the LG ThinQ platform.
Estimating Energy Savings with the ThinQ App
The energy‑monitoring tab breaks down consumption by day, week, and month, letting you see the impact of schedule changes instantly. Pair that data with the U.S. Department of Energy recommendations for thermostat set‑points to calculate potential savings. Small adjustments—like raising the set temperature 1 °F during peak hours—can cut cooling costs by 3‑5 % over a season. See the energy‑saving temperature guide for optimal set‑points.
