The short answer
This is the value-versus-king fight of the inverter class. Buy the Dreo if you want the quietest, cheapest path to inverter cooling; buy the LG if app control and brand pedigree are worth $80 to you.
The Dreo U-Shaped DR-HAC002 (8,000 BTU, 15.0 CEER, 42 dB, ~$349, 4.6★ across 1,300+ owners) undercuts the LG Dual Inverter LW8022IVSM (8,000 BTU, 15.2 CEER, 44 dB, ~$429, 4.4★ across 1,700+) on price while beating it on measured noise and owner rating. LG’s case rests on three real things: a marginal efficiency edge, the full ThinQ app/voice/scheduling stack, and the service network of a global appliance brand.
Head-to-head on the specs that matter
Dreo U-Shaped: 8,000 BTU · ~350 ft² · 15.0 CEER · 42 dB · ~$349 · 4.6★ / 1,300+ · no app.
LG LW8022IVSM: 8,000 BTU · ~340 ft² · 15.2 CEER · 44 dB · ~$429 · 4.4★ / 1,700+ · ThinQ app + Alexa/Google + scheduling.
Both are true dual-inverters with ENERGY STAR certification, so the efficiency story is nearly a tie — 15.2 vs 15.0 CEER is a couple of dollars a year, not a decision. The real separators are the $80, the app, and the shape of the chassis.
The U-shape: Dreo’s structural advantage
The saddle design does something no standard chassis can: the window closes onto the unit, putting glass between you and the compressor. That is how a 42 dB machine sounds even quieter than the number suggests — and why it holds the top of our quietest air conditioners ranking. The honest trade-offs from owner data: occasional compressor rattle reports, and a more involved bracket install that needs a compatible window. If you came here comparing U-shapes generally, the GE Profile ClearView saddle is the other window-preserving design we have vetted.
Where LG earns its $80
The smart stack is real: ThinQ app, Alexa and Google voice, and scheduling — the Dreo has none of it. Pre-cooling a room from your phone or folding the AC into home routines is the concrete daily win. The pedigree is real too: LG’s parts availability and service network outclass a young brand’s, which matters on a 10-year appliance. And at 15.2 CEER it is the single most efficient unit in our 49-model catalog — see the inverter guide for why that class leads, and LG vs Midea for how LG stacks against the other volume brand.
The verdict — and the bigger-room option
Buy the Dreo for a bedroom or office where quiet and value lead: it is measurably quieter, $80 cheaper, and better-rated by the people who own it. Buy the LG if smart control is part of how you live, or you want the safest long-term service bet in the class.

Frequently asked questions
Is Dreo as good as LG?
On the core cooling specs, yes — and on some it is better. The Dreo U-Shaped matches the LG LW8022IVSM’s 8,000 BTU inverter cooling, measures 42 dB to LG’s 44 dB, costs about $349 to LG’s $429, and rates 4.6★ to LG’s 4.4★. LG answers with slightly better efficiency (15.2 vs 15.0 CEER), a full app/voice smart stack the Dreo lacks entirely, and a longer parts-and-service track record.
Is the Dreo U-Shaped quieter than the LG Dual Inverter?
By the numbers, slightly: 42 dB versus 44 dB on low. The U-shape adds a second, structural advantage — you close the window sash onto the unit, so the compressor sits outside the glass. In practice the gap feels bigger than 2 dB, which is why the Dreo tops our quietest-ACs ranking.
Does the Dreo U-Shaped have an app?
No — and that is its clearest real weakness against the LG. There is no app, no Alexa or Google control, and no scheduling beyond the onboard timer. If a smart-home routine or remote pre-cooling matters to you, the LG’s ThinQ stack is the genuine differentiator that justifies part of its premium.
Which is better for a bedroom?
The Dreo, for most sleepers: 42 dB, the window-sash sound barrier, and an $80 saving. Choose the LG if you want to schedule cooling from your phone so the room is cold before bed — the one bedroom scenario where its smart stack beats the Dreo’s quiet.
What are the trade-offs with U-shaped units?
Two honest ones from our data: owner reports of occasional compressor rattle on the Dreo, and a bulkier install than a standard chassis — the saddle design needs a compatible window and careful bracket setup. Standard-chassis inverters like the LG avoid both at the cost of the open-window trick.
