A living room asks something different of a portable air conditioner than a bedroom does. In a bedroom the unit runs on its gentlest setting in a silent room, so the lowest figure on the sheet is the one that matters. In a living room it runs while you are there: early in the evening, after the sun has been on the windows all day, with people talking and the TV on. That means medium and high, the speeds makers print further down the table, when they print them at all.
This guide ranks portables sized for a living room by those figures. Our main portable air conditioner guide covers the whole category, including small rooms and the window units that beat portables on paper. If the unit is for sleeping next to, our bedroom portable guide ranks by the night setting instead.
Our picks are listed above, with full specifications for each.
The speeds a living room actually runs at
The headline figure on a portable AC box is nearly always the lowest one. LG's is "Down to 44 dBA", which is sleep mode. Whynter's descriptions say "as low as" 48 to 52 dBA. Midea prints a single lowest figure with no speed named, and Dreo only a lowest-speed one. Those numbers describe a setting you might use late at night in an empty room, not the hour after dinner.
On a hot evening the unit starts on high to pull the room down, then settles to medium. That is where the figures climb. On LG's own table, the step from sleep to high is 9 dBA, from 44 to 53. On Whynter's ARC-1230WN, the step from medium to high is 7 dB, from 49.5 to 56.5.
How much does that matter with the TV on? The US National Institute on Deafness and Other Communication Disorders puts normal conversation at 60 to 70 dBA. A unit listed in the low 50s on medium is below that range on paper, but not by much, and no maker states the distance its figure was taken from, so this is a rough guide and not a reading from your sofa. Remember the scale too. The National Park Service notes that an increase of 10 dB causes a doubling of perceived loudness, so the ARC-1230WN's 7 dB climb from medium to high is a large step, though short of a doubling. Our dBA explainer covers the weighting.
We rank only figures that share a unit and a speed label. Makers write these differently, and we quote each the way it is written. LG and Frigidaire write dBA. Whynter writes most of its tables in dB, sometimes under a dBA heading. We do not rank one against the other; why you cannot compare dB ratings across brands explains the reasons.
Written in dBA, medium speed:
- LG LP1419IVSM: 50 dBA.
- Frigidaire FHPC132AB1: 51 dBA.
Written in dBA, high speed:
- Frigidaire FHPC132AB1: 52 dBA.
- LG LP1419IVSM: 53 dBA.
- Whynter ARC-147WF: under 54 dBA.
Whynter's "under 54" is an upper limit, so we cannot place it against LG's 53; it is clearly below the 56 and higher figures further down this page. Whynter writes the ARC-147WF's figures only under dBA headings, so it goes in this group. The ARC-1280MX's 50/53/56 appears under a dBA heading in its spec table but as dB in its feature list, so we keep it with Whynter's dB tables below.
Whynter's tables, written in dB, medium then high:
- ARC-1030WN: 49.5 and 53.5.
- ARC-1230WN: 49.5 and 56.5.
- ARC-1050XP: 52.5 and 54.
- ARC-1280MX: 53 and 56.
Three things stand out. Within Whynter's own tables, where the method is at least the maker's own and consistent, the ARC-1030WN is lowest at both speeds. Of the two you could order from Whynter, the single-hose ARC-1050XP lists lower medium and high figures than the ARC-1280MX inverter. And bigger is louder at the top: the 12,000 BTU SACC ARC-1230WN matches the 10,000 BTU ARC-1030WN on medium but is 3 dB higher on high.
Frigidaire's FHPC132AB1 tops the dBA list on high, but we keep it out of the picks. Its spec sheet rates it at 8,000 BTU by the DOE test, and Frigidaire's website was not loading when we checked, so we could not confirm its price or whether it is still sold.
Some makers give a top figure that fits no group. BLACK+DECKER says its BPP10WTB runs "at 58 dBA on highest setting", in a bullet that describes an 8,000 BTU SACC unit on a page for a 10,000 BTU SACC model. Honeywell lists its HX4CESAWG0 at 57 dBA as both the minimum and the maximum. De'Longhi's only current US portable lists 53 under "Noise pressure level min max" with no unit, and its FAQ says its portables are "Normally" around 55 dBA. Midea's 12,000 BTU Duo says "as low as 42 dBA" and nothing more; our Midea decibel guide lists every Midea figure.
Size by SACC, not by the number on the box
Portable ACs carry two cooling figures. Honeywell explains that ASHRAE is the old standard, tested in conditions "ideal for air conditioning performance", and that SACC, the seasonally adjusted cooling capacity, comes from the Department of Energy's newer test. The SACC figure is always lower, and Honeywell adds that the unit has not changed, only the test.
The gap is wider than buyers expect. Frigidaire's FHPC132AB1 is 13,000 BTU by ASHRAE and 8,000 by the DOE test, yet the same sheet gives a cool area of 600 square feet. Whynter's ARC-147WF is 14,000 ASHRAE and 10,000 SACC. De'Longhi's PAC EM370 is 11,500 ASHRAE and 6,700 SACC, on a page titled 500 sq ft.
ENERGY STAR's sizing chart for room air conditioners gives 10,000 BTU for 400 to 450 square feet, 12,000 for 450 to 550 and 14,000 for 550 to 700. A living room often brings three of the chart's adjustments: increase capacity by 10 percent if the room is very sunny, add 600 BTU for each person beyond two who regularly uses the room, and 4,000 BTU if the unit serves a kitchen. The chart is written for window and wall units, but it is a fair guide if you read it against the SACC figure.
Here is the problem for a living room. Most portables in this guide sold as 14,000 BTU (ASHRAE) are 10,000 BTU by SACC. The only units with 12,000 BTU SACC that we found were the Whynter ARC-1230WN, Midea's 12,000 BTU Duo and Danby's DPA120B9IWDB-6, which Danby's site marks as discontinued. If your open-plan space is 600 square feet with a kitchen in it, no portable we found is big enough by ENERGY STAR's chart. Our guide to the quietest mini-split for a living room covers the units that are.
One hose or two
A single-hose unit cools the room's air and blows the condenser's heat out of the window using room air. Danby puts it plainly: dual-hose models have an intake and an exhaust hose, while with single-hose models the air to be conditioned is taken in from the room. Whynter says its dual-hose system "draws in fresh outdoor air to cool your space, then exhausts warm air outside, delivering faster, more efficient cooling than single-hose models."
No maker we read says a second hose makes a unit quieter. Whynter's lowest medium and high figures belong to its hose-in-hose models, the ARC-1030WN and ARC-1230WN, but those are also its inverter models, and its single-hose ARC-1050XP is not an inverter. We cannot tell from the tables which feature lowers the figure, so we credit neither.
What a second hose does change in a living room is the window. Whynter's hose-in-hose models put both air paths in one wide hose; on the ARC-1030WN it is 12 by 7.25 inches. The ARC-147WF has two 5.9 inch hoses. Plan for the bulk at the window you will use.
Inverter or on and off
ENERGY STAR describes a conventional compressor as working like an on/off switch, either on at maximum capacity or off, alternating to hold the temperature. A variable-speed compressor varies its output instead, which ENERGY STAR says lets a room air conditioner quietly cool the room. Whynter says its NEX inverter runs "noticeably quieter than conventional portable air conditioners".
In a living room the on and off cycle is the sound you notice during a quiet scene. BLACK+DECKER's page notes "a 3-minute delay before the compressor begins cooling air after settings have been changed", so a non-inverter unit restarts with a pause and then a step up in sound.
The efficiency gap is large too. Among our picks, the three Whynter inverters list CEERs of 12.1 to 14.7, and the two non-inverters 7.83 and 7.9. LG gives no CEER for the LP1419IVSM. A unit that runs every summer evening for hours will show that difference on the bill.
The window kit and the seal
A living room window is often wide, or it is a sliding patio door. Check the kit before you buy:
- Whynter ARC-147WF: 20 to 46 inches.
- Whynter ARC-1050XP: 28.3 to 82 inches, in three plates.
- Whynter ARC-1280MX: up to 82 inches.
- Whynter ARC-1030WN and ARC-1230WN: 82 inches in the feature list and 49 inches in the spec table, so ask Whynter before you rely on either.
BLACK+DECKER's kit includes a foam seal, and it says to use the unit in double hung or sliding windows only, not crank windows. Honeywell also suggests weatherstripping gaps in windows and doors and keeping them closed while the unit runs. Danby adds that the hose should be properly installed at both ends, not over extended, and that the unit should sit as close to the window or patio as possible.
Condensate on a humid evening
Every portable pulls water out of the air. What the maker does with it decides whether the unit stops mid-film.
- Whynter: a "patented auto drain function fully exhausts all condensate automatically in most environments", with gravity and manual drains as backup.
- LG: an Auto Evaporation System that "minimizes draining".
- BLACK+DECKER: "bucket-less, self-evaporating operation".
- Dreo: drainage-free in environments below 90 percent humidity.
- Honeywell and Frigidaire: continuous drain options, with a drain tube not included on the Honeywell.
None of these is described as a pump. Whynter lists "Pump Feature - No" for the ARC-1230WN and ARC-147WF, and Frigidaire lists "Pump Feature No" for the FHPC132AB1, so a continuous drain needs a floor drain or a bucket lower than the port. Danby gives one more reason to leave the water alone in cooling: it says not to drain the unit in cool mode, because it is designed to use the collected water in the cooling process.
Where to put it in an open-plan room
Honeywell says portable units cool down the immediate area around the unit, which matters in an open-plan space: put the portable where you sit, not where the room is hottest. The hose decides the rest, since the unit lives at the window.
Stand it on a level, firm floor. BLACK+DECKER says to place the BPP10WTB on a level, smooth floor strong enough to hold its weight "for low noise and vibration". Honeywell's tip for compressor noise is a thick foam pad, a rug or an old blanket under the unit to absorb vibration; if you try that, keep the unit level. In an open-plan room the portable joins the fridge, the dishwasher and the range hood, and our page on planning a quiet open-plan kitchen sets out what runs when on that side.
How we chose
We started from the portables in our main guide and added the living room sizes from Whynter, Honeywell, BLACK+DECKER, Frigidaire, Danby and De'Longhi. We read each maker's product page, spec table or spec sheet on October 4, 2026, and recorded each noise figure with its unit and the speed label the maker gives. We ranked only within groups that share a unit and a speed label, and we put units with only a lowest-speed figure, or a figure with no speed, in What We Also Considered. Frigidaire's website was not loading that day; we used the spec sheet Frigidaire hosts and could not check its price. Prices on the cards are the makers' own, from the dates in the catalog.
We did not measure any of these units, in a living room or anywhere else. Every figure here is the maker's own, quoted with the unit and speed it gives, and none of the makers states a measuring distance or test standard. Your room's size, its furnishings and where you sit will change what you hear.
