Is it normal for the new 'AI Air' models to feel different than regular AC?

The LG dual processor units use a combination of a motion sensor—usally a PIR sensor—and an inverter algorithm that they've rebranded as **AI Air** for the 2026 lineup. What you're seeing isn't a defect; it's the unit trying to follow you around or avoid you depending on the mode. These sensors detect body heat and movement to decide wether to blast the air directly at you or angle the vanes toward the ceiling for indirect cooling. It's basically a fancy version of the old 'Follow Me' feature but with much more frequent adjustments. Those sudden ramps in fan speed usually happen becuase the processor detected a change in the room's thermal load, like someone walking in or a door opening. The dual-processor bit is mostly there to handle the faster data polling from the sensors without lagging the compressor control. It's trying to maintain a very tight temprature window rather than the wider swings you get with older on/off or basic inverter units. But if the sensor is hitting a wierd reflection or if you're just sitting near the edge of its detection zone, it can get twitchy and hunt for the right angle.

Most of the time, the AI label is just a marketing wrapper for a more aggressive **PID controller**. They want to sell the idea of smart living, but it’s realy just math and heat mapping. If the hunting is driving you crazy, you shoud look for the 'Comfort Air' or 'Manual' override on your remote. Most LG units let you lock the vanes in a static position while still letting the inverter ramp up and down naturally. Personally, I find the AI mode works best in larger living rooms where people are moving around frequently. In a bedroom or a small office, it’s usually overkill and ends up being distracting. If you want a consistent breeze, just set it to a fixed fan speed and a 45-degree angle. You’ll still get the efficiency benefits of the dual inverter without the unit constantly second-guessing where you’re sitting. It's not special air, just more complex logic for moving it around.

While the spatial logic is flashy, these "AI" branded algorithms are also attempting to calculate the latent heat load by correlating relative humidity with the evaporator coil's saturation temperature to prevent that "clammy" feeling often associated with oversized inverter units running at minimum hertz. I’ve noticed on my own unit that if I leave the "AI" mode engaged during high humidity, it prioritizes moisture removal over pure sensible cooling, which explains those sudden fan speed drops you’re seeing since excessive airflow can actually re-evaporate condensate back into the room. Are you seeing any specific "sensing" icons on the display when it ramps up or is it just an acoustic observation?

OMG that sounds like straight-up sci-fi! I’m totally new here but reading about these units tracking you around the room is blowing my mind. It’s like living in the future! Does the sensor pick up on pets too? I have a giant golden retriever who never stays in one spot and I’m wondering if the AI whould just spend all day trying to cool him down instead of me lol. Has anyone tried these with high-energy dogs?

Look, the real value in those LG Artcool or DualCool units isn't the sensor tracking; it's the energy management. If you’re using the ThinQ app, check the 'AI Smart Diagnosis.' I’ve seen the 2026 models throttle the compressor based on historical utility peak pricing if you've got it synced.

I’ve been messing with the 1.5-ton DualCool Prestige lately. The 'AI' is basially just a glorified adaptive algorithm for the BLDC motor. If the hunting bugs you, check your 'Smart Care' threshold settings. Most people don't realize these units are trying to predict a 0.5-degree drift before it even happens. It’s overkill for a bedroom. Personally, I just lock mine to 24C and let the R32 do its job.

Update: I started using the ThinQ app as suggested, and seeing the energy management data is acutally pretty cool. However, the PIR sensor is still acting super jumpy whenever I move. Has anyone found a way to disable the 'follow me' feature while still letting the AI handle the humidity and compressor speed? It’s getting a bit distracting.
