Soleus Air 8,000 BTU Saddle Window AC

The small-room version of Soleus's patented over-the-sill design, sold as the WS4-06EW-201 with Wi-Fi (an earlier non-Wi-Fi WS3-06E-201 is now discontinued but still floats around retail). For a bedroom or office up to about 275 sq ft it has a genuinely compelling story: 38 dBA on low — legitimately competitive with inverter U-shapes — because the loud half of the machine hangs outside below the sash, with the sill and closed window between you and the compressor. Consumer Reports has tested the platform, and owner reviews consistently mention being able to sleep directly next to it. The catches mirror the 8K: single-speed compressor (so it cycles on and off rather than modulating), modest efficiency that trails every U-shape inverter here, and a roughly $500 street price that buys a lot more cooling in any other format. The fit constraints are non-negotiable — measure sill depth (11 in max) and sash travel before ordering, because 'it didn't fit my window' is the most common negative review. Compared to the GE ClearView 10K, this is cheaper, lighter, and simpler but far less powerful and less efficient; compared to a Midea U 8K it's quieter-adjacent at low speed but louder over a night of cycling. A niche unit that's perfect when the niche fits.

The biggest ClearView is the unit Bob Vila's 2026 U-shape roundup called the upgrade pick, and it's the only way to get 12,200 BTU — enough for a 550 sq ft living room — without giving up your window. The saddle format hangs the machine below the sash, so where a Midea U 12K still fills the lower third of your glass, the ClearView leaves the view essentially untouched, and its inverter runs down to 40 dB with expert consensus around 8.6/10. Efficiency is a slight step behind the U-shapes (CEER 14.6 versus 15), and Bob Vila's testers noted the lack of a swing mode — air comes out where it comes out. The bigger caveats are logistical: at $585 (GE's own clearance price; $609 list) it's the most expensive non-heat-pump unit in the category, the 4.5-13.75 inch wall-depth window excludes some brick and stone buildings entirely, and GE's product page now marks this generation 'no longer being manufactured,' which in 2026 means genuine bargains as retailers clear stock but also some warranty-support uncertainty about what replaces it. Owners echo the 10K's story: near-invisible in the window, very quiet, occasionally hum-through-the-sill (foam shims fix it), and SmartHQ app pairing that takes patience. If the view matters and the wall fits, nothing else this powerful disappears like it does.

GE's ClearView solves the one thing U-shapes don't: the view. Because the unit saddles over the sill and hangs below the sash, you get nearly your entire window back — reviewers at Tom's Guide called it the least visually intrusive window AC ever made, and owners echo that it's the only unit guests don't notice. It's also legitimately quiet: 40 dB on low from an inverter compressor, with GE marketing the Profile line as the quietest window AC brand in the US. The PHNT10CC (10,300 BTU, 450 sq ft, CEER 14.6) replaced the AHTR10AC, and GE's site now flags this generation as no-longer-manufactured too, so 2026 looks like a transition year — retailers like Home Depot still stock it around $480, and clearance pricing dips far lower. Downsides are physical: 80 lbs, an awkward straddle-lift install, and that 4.5-13.75 inch wall-depth window — brick buildings with deep sills can simply not fit it. Owner threads also flag Wi-Fi/app flakiness and, in a minority of cases, a resonant hum transmitted through the sill that takes foam shimming to kill. Versus the Midea U 10K it's about $100 more and slightly less efficient, but nothing else this size preserves your window like it.

The Gradient is a different species from everything else here: a true cold-climate heat pump in a window-saddle body, delivering 9,300 BTU/hr of cooling and 9,000 BTU/hr of heating at full capacity down to 5°F (still functioning at -13°F), all from a regular 120V outlet. That means one machine replaces both your window AC and your radiator or space heater — the reason NYC's housing authority ordered thousands for apartment retrofits and why it made Forbes' innovative-technologies list. The variable-speed compressor runs 38 dB(A) on low, the design keeps your entire window view, and the 5-year warranty embarrasses the 1-year industry standard. So what's the catch? Price: about $3,800 per unit, roughly ten Midea Us. This only pencils out if you'd otherwise pay for electric resistance heat (it can cut those bills up to 50%), if a mini-split install is impossible or unpermitted, or if the 30% federal heat pump tax credit and state incentives apply to you. Early owner reports are positive on comfort and shocked by shoulder-season efficiency, with gripes limited to app maturity and the sheer bulk in smaller windows. Note that Gradient ended support for its Gen 1 'Moderate Weather' unit in August 2025 — the All-Weather 120V is the current product and the one to buy.

The LP1022FVSM is the successor to LG's cult-favorite LP1419IVSM (now discontinued) and carries the same Dual Inverter compressor that made that unit the quietest portable AC most reviewers had ever tested — TechGearLab measured it quieter than every rival at comparable output, dipping into the mid-40s dBA. It's a single-hose design, which is the honest caveat: its 14,000 ASHRAE becomes 10,000 SACC, and in triple-digit heat it slightly depressurizes the room, pulling warm air in through cracks — physics the dual-duct Midea Duo avoids. In moderate conditions, though, owners adore this thing: the inverter ramps down to a whisper instead of cycling, ThinQ is one of the more polished smart-home apps in the category, and the auto-swing vent plus auto-evaporation make it a set-and-forget bedroom appliance. Watch the price: LG lists it near $700, but it's still widely available through Amazon and appliance dealers, and it goes on sale regularly. Reddit's consistent take in LP1419IVSM/LP1022FVSM threads: buy it specifically for sleep noise, buy the Duo for raw cooling per dollar. Note that LG has been winding down its US portable lineup, so grab it while stock lasts — there's no announced replacement.

The Pinguino Arctic Whisper Extreme is De'Longhi's US flagship, and it takes a different path to comfort than the inverter crowd: heavy sound insulation and a low-RPM 'Arctic Whisper' mode that cuts noise up to 50%, holding around 50 dB even near max — reviewers at Gadget Review and Reviewed both singled out how pleasant it sounds for a fixed-speed machine. Its EcoRealFeel mode targets a comfort blend of temperature and humidity rather than a raw setpoint, and testers praise its surprisingly low power draw. Now the honest ledger: this is a single-hose unit rated 14,000 ASHRAE but just 8,600 SACC, and De'Longhi's 700 sq ft claim is marketing — at 8,600 honest BTUs, think 400-450 sq ft in real heat, where the Midea Duo's 12,000 SACC will simply out-cool it. There's no Wi-Fi or voice control (the Bluetooth remote monitors temperature at your seat, which is clever but no app substitute), no inverter, and at 83 pounds it's the heaviest thing in the category. Owners love the Italian styling, easy install, and bedroom-friendly acoustics; they grumble about price, weight, and that coverage claim. Buy it for looks and steady quiet in a mid-size room — not for max cooling per dollar.
