The short version: LG’s ThinQ Smart Thermostat is built to work best with LG-branded HVAC equipment (including LG mini-splits and heat pumps), sold mainly through LG’s dealer network with limited Best Buy availability. Independent feedback we found points to real, recurring complaints about the ThinQ app’s reliability and LG’s support quality — worth weighing seriously if you’re choosing between LG and a dedicated thermostat brand.

Who It’s For

Homeowners with LG HVAC equipment (heat pumps, mini-splits, or LG-compatible forced-air systems) who want a single ThinQ app to control their thermostat alongside other LG smart appliances. If you don’t already have LG HVAC equipment, there’s little reason to seek this thermostat out specifically over an established retail brand.

Setup & Compatibility

The ThinQ thermostat is designed to work best with LG-branded HVAC systems, and installation is typically handled through an LG dealer alongside equipment work, though some retail availability exists (Best Buy, limited). As with other equipment-tied thermostats, confirm exact compatibility with your specific furnace, AC, or heat pump model before buying, especially if pairing with non-LG equipment.

App & Real-World Feedback

This is the area where we found the most specific, independently reported feedback, and it’s not particularly favorable:

  • Users describe the ThinQ app as glitchy, with a genuinely difficult initial setup process.
  • Specific complaints include blank-screen issues that persisted even after fully reinstalling the app.
  • Some users report the system struggling to actually regulate temperature to the set point, leading to discomfort.
  • The app and connected heat pump units reportedly don’t allow setting the heating temperature below 60°F, limiting energy-saving setbacks while away — the same limitation reported for other LG-adjacent (and Fujitsu) mini-split control apps.
  • Customer support feedback is a recurring pain point: users report generic responses, long phone calls without resolution, and multiple support reps unable to help with third-party integrations like HomeKit.

We’re including these specifics because they appeared across multiple independent sources (app-store reviews and consumer Q&A platforms), not as an isolated complaint.

Pros & Cons

Pros:
– Ties into the broader LG ThinQ smart-appliance ecosystem
– Works well specifically with LG-branded HVAC equipment
– Alexa and Google Assistant support

Cons:
– Recurring, specific app complaints: difficult setup, blank-screen bugs, temperature regulation issues
– Minimum heat setpoint reportedly capped at 60°F, limiting away-mode energy savings
– Customer support feedback is notably weak, including limited help with third-party smart-home integrations
– Limited retail availability; mostly a dealer-channel product
– Independent, large-sample owner reviews (star ratings, aggregated retailer feedback) are thin compared to established thermostat brands

The Recommendation

If you already have LG HVAC equipment and want everything in one ThinQ app, this is a functional option, but go in aware of the app and support complaints documented above — ask your installer whether recent firmware updates have improved stability, and check current app-store reviews yourself before buying. If you’re not tied to LG equipment, an established retail thermostat like ecobee or Honeywell will give you a much deeper base of independent, verifiable feedback and generally stronger app support.

Frequently Asked Questions

Is the LG ThinQ app reliable?
Independent feedback points to real complaints: difficult initial setup, blank-screen bugs, and temperature regulation issues. Check current app-store reviews before buying, since apps change between updates.

Does the LG ThinQ thermostat have a minimum heat setting?
Users report being unable to set heating below 60°F, which limits how much you can set back the temperature while away.

Does the LG ThinQ thermostat work with HomeKit?
Some users report difficulty getting support help with third-party integrations like HomeKit; confirm current compatibility directly with LG or your installer before assuming support.

Is the LG ThinQ thermostat sold at retail?
Mostly through LG’s dealer network, with limited availability at Best Buy.
