LG LP1022FVSM Dual Inverter
The LG LP1022FVSM Dual Inverter is a 10,000 BTU SACC portable air conditioner rated for 450 sq ft, with a 44 dB noise figure, a variable-speed dual inverter compressor and Wi-Fi through the LG ThinQ app. It scores 8.7 out of 10: strong on quiet and efficiency, average on raw cooling, and carrying one structural compromise its closest rivals do not - a single exhaust hose. It fits one medium room, not an open plan, and it suits buyers who already live in the LG app ecosystem. The decision is narrow: at $450 it sits $20 above the Midea Duo 12,000, which delivers the same 10,000 SACC at 42 dB with a dual hose. If ThinQ is not worth that $20, this is not the unit.

The box says 14,000 BTU. The room gets 10,000.
LG markets this unit at 14,000 BTU ASHRAE. The number that matters is the DOE SACC rating, and here it is 10,000 BTU, with rated coverage of 450 sq ft. ASHRAE is a lab figure measured under fixed conditions; SACC is the seasonally adjusted rating that accounts for the heat a portable unit lets back into the room, including the air a single-hose design pulls out of it. The gap between those two numbers is the honest tell on any portable air conditioner. At 10,000 SACC from 14,000 ASHRAE, the LP1022FVSM keeps about 71 percent of its headline number, which is high for a single-hose unit: the Frigidaire FHPW122AC1 delivers 8,000 SACC from 12,000 ASHRAE, and the Shinco 12,000 delivers 7,500. Context cuts both ways, though. The Midea Duo 12,000 reaches the same 10,000 SACC starting from only 12,000 ASHRAE, because a hose-in-hose design does not have to fight its own exhaust. The LG needs 2,000 more lab BTU to arrive at the same real number. That 10,000 SACC is what earns the cooling score of 8 rather than a 10. For a 450 sq ft bedroom or home office it is correctly sized. For a 550 sq ft living room it is not, and no amount of app control changes that.
The single hose is the compromise you are paying around
Five units in this catalog use an inverter compressor. Four of them vent through two hoses or a hose-in-hose design. The LP1022FVSM is the one that does not. A single-hose unit draws the air it uses to cool the condenser from the room it is cooling, then pushes that air outdoors. The room ends up slightly below outside pressure and pulls replacement air back in through door gaps, window frames and vents. That is the mechanism the SACC rating exists to capture, and it is already priced into the 10,000 BTU figure. There is a real argument on the other side. One hose means one thing to route, one seal to get right and a simpler window kit - which matters in a casement window, a narrow sash, or a rental where the install has to come out cleanly at the end of the lease. Plenty of buyers choose single hose for that reason alone and are not wrong to. What is harder to defend is paying dual-hose money for it. At $450 this unit sits above the $430 Midea Duo 12,000, which carries the same SACC rating, a lower noise figure and the hose architecture the LG lacks. The install advantage is real. For most rooms it is not worth $20.
What the two 9s actually buy: 44 dB and a modulating compressor
Quiet scores 9 on a 44 dB figure. Set against the rest of the catalog that is a different class of machine: the fixed-speed units run 49 to 56 dB, from the Frigidaire FHPW122AC1 at 49 dB, through the BLACK+DECKER 14,000 at 54 dB, to the SereneLife 12,000 at 56 dB. Against the three Midea Duos at 42 dB, the gap is 2 dB - which almost nobody hears in a real bedroom. One caveat on that number, stated plainly: the 44 dB value comes from LG dual-inverter test data for the product family, not from a measurement specific to this model. It is flagged as a family figure in the source data and should be read as a class estimate, not a promise. Efficiency scores 9 on the dual inverter compressor. A fixed-speed portable unit runs at full output, hits the setpoint, shuts off, and slams back on a few minutes later. An inverter modulates output instead, holding temperature at partial load, so the noise floor stays steady rather than cycling between loud and silent. In a bedroom, that behavior tends to matter more than the decibel number on the box.
Where the $450 goes - and where it does not
Street price is around $450, in a $400 to $550 band. Three units in this catalog frame what that money is actually doing. Twenty dollars below it, the Midea Duo 12,000 Inverter at $430 matches the 10,000 SACC rating and the 450 sq ft coverage, runs at 42 dB, uses a dual-hose design and weighs 68 lb against the LG's 74 lb. It scores 9.3 overall against this unit's 8.7. Fifty dollars above it, the Midea Duo 14,000 Inverter at $500 steps up to 12,000 SACC and 550 sq ft, still at 42 dB, still dual hose, and posts a 10. Seventy dollars below it, the BLACK+DECKER 14,000 with heat at $380 hits the same 10,000 SACC and 450 sq ft and adds a heat mode - but it is fixed-speed, 54 dB, and has no app at all. It scores 5.7. So $450 buys LG hardware and ThinQ integration, and no spec advantage over anything nearby. For a household already running LG appliances on ThinQ, that is a legitimate reason to pay it. For anyone else, the money works harder $20 down or $50 up. Near the top of its band, at $550, this unit stops making sense.
8.7 out of 10, and the three units ahead of it
An 8.7 is a good score, not a great one, and the shape of it is worth reading. This unit posts an 8 for cooling and 9s for quiet and efficiency. It does not lead a single dimension in the catalog. Three models outrank it overall - the Midea Duo 14,000 at 10, the Duo 14,000 with heat at 10, and the Duo 12,000 at 9.3 - and all three are the same Midea platform. The shortest honest summary is that this is the best portable air conditioner in the catalog that is not a Midea Duo. It does hold one genuine distinction: it is the only unit outside the Duo line that pairs an inverter compressor with a sub-45 dB figure. The other non-Midea inverter, the Whynter ARC-1230WN, is rated 49 dB. The specific gaps are easy to list. No heat mode, so it is a summer-only appliance. At 74 lb it is the second heaviest of the inverter group, behind the 76 lb heat-pump Duo, which makes moving it between rooms a two-person job. And a single hose in a bracket where dual hose has become the default. None of that is disqualifying. All of it is why the number is 8.7 and not 9.5.
Who it's for / who it's not
Who it's for
- You already run LG appliances on ThinQ and want the air conditioner in the same app.
- A 450 sq ft bedroom or home office where a 44 dB inverter is the point.
- A casement or narrow window where a single-hose kit installs and comes out more cleanly.
- You want app scheduling and remote start without dropping to a 54 dB fixed-speed unit.
Who it's not for
- A 550 sq ft living room, or any room you also want heated in winter.
- Spec-per-dollar buyers: the Midea Duo 12,000 costs $20 less at 42 dB with dual hose.
- A garage or workshop where 54 dB is fine - $380 buys the same 10,000 SACC.

We score every portable AC in our catalog on the specs that matter.
Best portable air conditioners of 2026These scores come from a deterministic engine reading published specifications - SACC rating, rated coverage, decibel figure, compressor type, hose architecture, weight and features - rather than hands-on testing. Habilytics scores published specs and says so. The 44 dB value here is an LG dual-inverter family figure, not a model-specific measurement, and is flagged as such.
