12 Best Portable Air Conditioners for Apartments (October 2026)

Apartment AC is one of those problems that never goes away. The building has no central air, the window crank is the wrong shape for a window unit, and the lease says no drilling. That leaves portable air conditioners for apartments as the realistic answer, and it is a bigger decision than most buyers expect because the differences between models show up in ways a spec sheet does not explain.

We spent weeks going through the specs, published noise ratings, compressor types and renter complaints behind the twelve models below. The pattern that kept repeating in the forums is worth stating up front: dual-hose design and inverter compressors matter far more in a sealed apartment than they do in a house with open doors.

If you want the short version, the SereneLife SLPAC8 is the most balanced pick for a typical apartment, the DREO 318S is the one to buy when a bedroom is next to a wall you share with someone else, and the HUMHOLD 16,000 BTU is for open-plan living rooms that need serious tonnage. Everything below explains why.

One more note before the picks. We only list a unit we can justify with published specifications, and we flag the honest limitations of each one. Anyone who lists a dozen air conditioners without a single drawback listed is selling you something.

Our Top 3 Portable ACs for Apartment Living in 2026

These three cover the majority of apartment situations we get asked about. Each one earns its place for a different reason, and the reasoning matters more than the ranking.

We also use a related guide on camping air conditioners if you split your summers between an apartment and a site, since the power constraints overlap.

Comparing All 12 Portable Air Conditioners Side by Side

No competitor publishes a full spec comparison, so here is ours. Every figure comes from the manufacturer listing for the exact model, and the ASHRAE versus DOE BTU difference explains why some coverage numbers look inflated next to others.

1. SereneLife SLPAC8 - Best Overall for Apartments

The SereneLife SLPAC8 is the one we keep coming back to because its efficiency rating is far better than anything else at this size, and in a studio or a one-bedroom apartment that gap shows up on the electricity bill every single month. It sits at 46.3 pounds, which is light enough for one person to carry up a flight of stairs without planning a second trip.

What surprised us is how narrow it is. At 12.8 inches wide it tucks against a wall or beside a desk in a way most 8,000 BTU bodies cannot, and the casters let you roll it between the bedroom and living area without lifting it at all.

The cooling itself is honest work rather than headline performance. It maintains its set point in a mid-sized room with a normal amount of sun, and the digital panel plus remote means you are not walking across the apartment to adjust it at night.

Why the 9.8 SEER rating changes the running cost

Most listings quote wattage, which tells you peak draw. The efficiency rating tells you how much cooling you get per unit of power over a season, and 9.8 is the highest figure among the twelve models here. For someone running a portable AC eight hours a night through a humid summer, that difference is the whole argument.

At 1,000 watts for most of that time, the math is straightforward. Multiply watts by hours, divide by 1,000 for kilowatt hours, then apply your local rate. Roughly 8 kilowatt hours a night is a very manageable number even in regions with high summer rates.

Noise: the honest limitation

At 55 dB this is not the quietest pick in the roundup, and users who share walls report it is noticeable in a dead-quiet room at night. The dual-motor design that helps it hit its temperature quickly is also the source of the sound. If your bedroom borders a shared wall and someone else is sleeping, read the DREO section before you commit.

Dehumidification and maintenance

The 1.2 liter per hour dehumidification figure is modest, so a genuinely humid climate will benefit from running the dedicated dry mode and expecting to empty a container. The mesh filter is a pull-out type, which makes the weekly rinse simple and is the single most effective thing you can do to prevent musty odors.

Give it three to four hours upright after unboxing before the first power-on, and expect a one-year warranty. In exchange you get the most efficient small model on this list and a body you can actually move through a hallway.

2. BLACK+DECKER BPACT10WT - Best Value for Larger Bedrooms

The BLACK+DECKER BPACT10WT is the pick when your bedroom is genuinely on the larger side and you want more cooling than a compact 8,000 BTU model offers. It carries the biggest review base in this roundup by a wide margin, and reading several thousand reviews is the fastest way to learn that it is a solid performer with one structural limitation.

That limitation is the single-hose design. One hose pulls room air in to cool the condenser and pushes hot air out, which means a sealed apartment room slowly develops negative pressure and the unit has to work harder for the same result. In a house with a hallway it barely matters. In a closed bedroom it does.

The Follow Me remote is the feature renters mention most. Press the button on the remote and it becomes the thermostat, so the unit follows you around with the remote rather than sampling air at the wall. It sounds trivial until you have used it in a room with uneven temperatures.

Reading the two BTU numbers correctly

This is listed as 10,000 BTU under the ASHRAE standard and 5,550 BTU under the DOE standard. Both numbers are honest, but they measure different things. The DOE figure is a more realistic estimate of sustained cooling in a real room, which is why some manufacturers now lead with the smaller number.

When you compare this against a model advertising 12,000 BTU, check which standard is being used. A 12,000 BTU ASHRAE figure and a 12,000 BTU DOE figure are very different machines. This is the single most common sizing mistake we see in apartment forums.

Where the noise lands

At 54 dB the compressor is audible in a quiet room, though the rotary scroll design produces a steadier hum than a reciprocating compressor typically does. Setting the fan to low and enabling sleep mode during the night usually keeps it below the level where it wakes you up.

What is actually in the box

The installation kit is complete: exhaust hose, window casement panel, water drain hose and a full-function remote. The washable filter pulls out without tools. A one-year limited warranty is typical for the category, and reviewers generally report solid multi-season durability on this specific model.

3. Shinco SPF1-12C - High-Output 12,000 BTU Cooling With Minimal Setup

The Shinco SPF1-12C is the brute-force option here. It is rated at 12,000 BTU under ASHRAE, which means it can pull a large, warm living space down to a comfortable temperature faster than any other single-hose model on this list, and it holds that temperature on a hot afternoon when lighter units start to give up.

The telescopic exhaust hose and window kit make setup genuinely tool-free, and the self-evaporating system handles up to 43.2 liters per day of moisture without you carrying a bucket to the sink. That combination is why it suits a humid apartment where dehumidifying matters almost as much as cooling.

Owners consistently point at cooling output relative to size. The trade is energy draw, and it is not a small one.

The wattage number deserves a second look

The listed 3,520 watts is far above every other model here, most of which sit between 750 and 1,450 watts. That is a meaningful difference on your utility bill and it can matter on an older apartment circuit. The SEER of 2.6 confirms what the wattage implies, so if running cost is your top concern this is the wrong unit to optimize around.

What you get in exchange is raw cooling capacity, and in a top-floor unit with west-facing glass that is often the more important consideration. Just know what you are choosing.

Dehumidification you will not have to babysit

Self-evaporation routes condensate through the cooling system where it re-evaporates. In dry air this works extremely well. In very humid air the system can outpace evaporation, so keep an eye on the drain and run a hose in the worst weeks of the season.

Controls and handling

The LED display, swing function and 24-hour timer cover the essentials, and the remote reaches about 23 feet. At 56.2 pounds with four casters it is heavy but manageable, and the taller 32.68-inch body means it needs a bit of clearance behind furniture.

4. DREO 318S - Best for Bedrooms Where Noise Counts

The DREO 318S is the one we recommend when a bedroom shares a wall with a neighbor or a partner who is a light sleeper. Its 45 dB published operating level is among the lowest of the single-hose designs here, and reviewers single out the noise isolation as the reason it feels different from a typical portable.

It is also the most genuinely hose-free option on the list. In cooling mode below 90 percent relative humidity the unit re-evaporates its own condensate, so there is no bucket in the hallway and no midnight trip to the bathroom. Renter posts on r/AirConditioners consistently single out the DREO line for exactly this reason.

The control options are the most complete here. App, voice through Siri, Alexa or Google Home, a touch panel and a remote all work, and the sleep curve lets you program a gradual temperature drift instead of a hard cycle that wakes you when the compressor kicks on.

Where the 100 sq ft figure comes from

The listed floor area of 100 square feet is conservative for an 8,000 BTU ASHRAE unit and confuses buyers who see it next to 350 sq ft claims elsewhere. In practice reviewers cool bedrooms considerably larger than 100 square feet comfortably, but the conservative figure is a fair warning in a top-floor unit with heavy sun exposure.

Where the spec is genuinely accurate is the humidity ceiling. Above 90 percent relative humidity the self-evaporating system cannot keep up, and a drain hose is included for exactly that situation.

Control range and reach

Temperature settings run from 61 to 86 degrees, and the included fan extends the air throw to about 14 feet, which matters in a long narrow apartment where the unit sits at one end. Sleep mode dims the display so there is no blue glow across the ceiling.

Weight and warranty

At 55 pounds this is not a unit you want to carry between rooms, so plan a single position and use the remote or app to change settings. The warranty is one year as standard with 24-hour customer service contact, which is thin but consistent with the category.

5. Antarctic Star 8,000 BTU - Lightest Unit to Haul Upstairs

At 39.7 pounds, the Antarctic Star 8,000 BTU is the pick for a walk-up with no elevator, a fourth-floor apartment, or anyone who has decided that carrying 60 pounds up stairs is not a thing they want to do in August. It is more than 10 pounds lighter than the median machine in this roundup, which is the difference between a one-person job and a two-person job.

Its 750-watt draw is also among the lowest in the roundup, and users report temperature drops of 15 to 20 degrees on hot days in rooms around the 350 square foot mark. Setup takes under 15 minutes with no tools.

It is also the simplest machine here. Four modes including a dedicated sleep mode, a remote and an LED touch panel, and nothing that requires an app.

Noise at the low setting

The 53 dB figure is achieved on the low setting, and sleep mode dims the display and auto-offs on a 24-hour timer. That is a reasonable bedroom companion, though it is not in the same class as the DREO or the two inverter units for pure quietness.

The window panel is the real constraint

Several users report the window insert panel is too thick for older or unusually narrow windows. Measure your window opening before ordering and check the included bracket range. It runs on 110 volts, so a converter is needed outside North America.

Durability is the open question

There is a smaller volume of reviews here than for the bigger names, and a handful of buyers report units failing after roughly a year of use. The manufacturer has replaced missing parts free of charge in at least some cases, and the warranty is one year. For a seasonal bedroom unit that is an acceptable trade, but we would not build a four-year plan around it.

6. Midea MAP05S1AWT-A - Best Fit for Studio Apartments

The Midea MAP05S1AWT-A is built for the apartment where floor space is the constraint, not cooling tonnage. At 11.54 by 11.61 inches it is among the narrowest bodies in the roundup, and shallow enough to tuck beside a bed or into a studio corner without eating circulation space.

It also gives you app and voice control at the entry level, which is unusual. Most models at this footprint stop at a remote, so being able to change the temperature from your phone during a meeting is a real quality-of-life difference in a small space.

Read the 150 sq ft figure honestly

This is the smallest coverage claim in the roundup, and it is the number to plan around. A true studio, a dorm room, a home office or a bedroom under about 150 square feet is exactly the target. Push it into a 300 square foot living area and it will run constantly without catching up on a hot afternoon.

That is also a function of the single-hose design. In a sealed studio the negative pressure effect means the unit works against itself, and the reciprocating compressor recovers less efficiently than a scroll type when it cycles.

Setup and controls

Tool-free installation with a five-foot hose and adjustable brackets covers 26.5 to 48 inch window openings, a wider range than most kits in this roundup. The 24-hour timer, three modes and 62 to 90 degree range cover the basics, and the washable reusable filter is designed for weekly cleaning.

Who should skip it

If you already have a dual-hose or inverter model available at a similar size, the efficiency gap over several summers is worth paying for. Choose this one for a genuinely small room and a tight floor plan, and it does that job well.

7. Hisense HAP0824TWD - Best Inverter and Dual-Hose Combo

The Hisense HAP0824TWD is the clearest example of why dual-hose design matters in an apartment. One hose pulls hot air out, the other brings fresh outside air in to cool the condenser, and because the room is no longer sealed around the unit, there is no vacuum effect dragging warm air back in at the intake.

Paired with an inverter compressor and a 15 SEER rating, this is the highest efficiency figure published for any machine in the roundup. In a sealed room it holds its set point without the constant on-off cycling that makes conventional compressors loud and expensive to run.

Quiet mode runs at 42 dB(A), which puts it alongside the HUMHOLD as the quietest published figure here. Drain-free operation in cooling mode removes the bucket from your routine entirely.

What to know about a Renewed unit

This listing is Amazon Renewed, which means inspected and warrantied by Amazon rather than the original manufacturer. The warranty is 90 days limited rather than a full year, and cosmetic wear is possible. What you get in return is access to the dual-hose inverter design at a substantially lower outlay than a new equivalent, and the core cooling hardware is the same.

Handling and installation

At 61 pounds it is one of the heavier units here, so plan the placement before you lift it. The snap-together window kit covers 25 to 50 inch openings, which is narrower than the Midea kit. Two hoses mean more window width is used, so measure carefully in a casement or narrow frame.

Smart control and modes

Wi-Fi with the ConnectLife app, plus Google Assistant and Alexa voice control and a remote, cover the interaction options. Three operating modes and a 24-hour on and off timer round out the feature set. Note the listed 8,000 DOE figure equals roughly 10,000 ASHRAE BTU.

8. HUMHOLD 16,000 BTU - Highest Cooling Output for Open-Plan Spaces

The HUMHOLD 16,000 BTU is for the apartment where portable cooling stops making sense on paper and starts making sense in practice: a large open-plan living area, a converted loft, a sunroom, or a main living space that doubles as a work area for most of the day. At 16,000 BTU ASHRAE it has the highest cooling output in this roundup by a wide margin.

Buyers report replacing window units and even struggling central systems with it, and one owner cooled a 500 square foot basement bedroom and a 30-foot RV with the same machine. The dual-hose layout is why the temperature drop is so fast.

The overheat cutoff is the one limitation to understand

Built-in overheat protection drops the unit to fan-only when outdoor temperatures climb above roughly 80 F. In a mild summer that never triggers. During a serious heat wave it means the unit will not cool, and you need to know that before the hottest week of the year rather than during it.

Sleep mode and inverter cycling

Quiet mode runs at 42 dB with a timer adjustable from half an hour to 24 hours. The inverter compressor ramps rather than switches, which is what makes both the low noise and the claimed 40-plus percent energy saving possible compared with a conventional fixed-speed compressor.

Dehumidification and mobility

Three-in-one operation covers cooling, a three-speed fan and dehumidify mode rated at 95 pints per day. The self-evaporating water system needs no daily draining, and a drain hose is included for humid rooms. Four heavy-duty wheels and hidden side handles make it movable despite the 61-pound weight.

9. Frigidaire FHPC082AC1 - Low-Maintenance Cooling From a Big Brand

The Frigidaire FHPC082AC1 is the choice for buyers who want a name they already recognize on a large appliance and a unit that needs very little attention. No bucket draining in normal cooling, a washable dust filter with clean-filter alerts, sleep mode, dry mode and auto restart if the power flickers.

It is also tied for the lowest-rated model we included, and we think honesty requires saying so plainly. The 3.7 average reflects a real split: some owners run it happily for years, while a meaningful share report compressor failures well inside a couple of summers.

Two design details that annoy owners

One of the three rear air intakes has no removable filter, and the coils behind it are difficult to access. That combination is exactly the setup that produces the musty smell people describe after a season or two of use. The second issue is firmware behaviour that keeps the fan running after the compressor stops in cool mode, which exhausts cooled air instead of recirculating it.

Coverage and efficiency

It is listed at 150 square feet, and the SEER of 4.62 is the second-lowest figure here. Treat it as a small-room machine rather than a bedroom-and-living-area solution, and expect a higher running cost than an inverter unit of similar size.

What to check before buying

At 52 pounds it sits mid-range for weight but the window panel installation is reported as fiddly. The included remote has also drawn complaints about buttons that do not correspond to this specific unit, so test it on day one while you can still return it.

10. Garvee 14,000 BTU - Most Cooling Reach per Square Foot of Body

The Garvee 14,000 BTU packs more claimed coverage than anything else here, listing 750 square feet of cooling from a free-standing body. Buyers with small review bases rate cooling power relative to size very highly, and the no-drill window installation is genuinely convenient in a rental where you want nothing permanently attached to the frame.

The 90-pint dehumidifying capacity makes it a real option in humid regions, and the three-in-one operation covers cooling, fan and dehumidifying with an LED panel, 24-hour timer and sleep mode.

85 pounds changes the buying decision

This is the heaviest unit in the roundup by a wide margin, and weight matters more in apartment living than in a house with a ground-floor utility room. If you have an elevator or a ground-floor unit, that is manageable with casters and ergonomic side handles. If you have four flights of stairs and no lift, this is the wrong machine regardless of its capacity.

Read the warranty line carefully

The warranty field is listed as not applicable, which is unusual to see on a major appliance. With a 105-rating review base, there is simply less long-term data to draw confidence from than with a model that has accumulated thousands of reviews. If you want the largest coverage figure, buy it knowing you are buying on specifications rather than on a long service record.

Noise and placement

At 50 dB it sits mid-pack, which is fine for a living room and marginal for a shared-wall bedroom. Because of the size, plan its position carefully: it needs floor clearance and a window wide enough for the adjustable exhaust hose.

11. ZAFRO YAC-08CPD - Compact 12,000 BTU With Long Drainage-Free Runtime

The ZAFRO YAC-08CPD solves the problem that stops most people buying a 12,000 BTU machine in an apartment: bulk. It delivers that cooling capacity in a 12.99 by 14.80 by 23.23 inch body with casters, which is shorter and narrower than most units in the class and considerably easier to place against a wall.

It also carries the highest average rating of anything in this roundup at 4.4, with 76 percent five-star ratings. Reviewers describe fast, quiet cooling of bedrooms and camper vans, and the 72-hour self-evaporating system is the most generous drainage-free claim we found.

What drainage-free actually means

The system splashes condensate into the airflow so the ambient heat evaporates it. In typical indoor humidity that covers you for days at a time, which is why the claim is 72 hours. In a persistently damp room, or while running the dedicated dehumidify mode, expect to connect the included drain hose instead.

Sleep performance and controls

Sleep mode drops noise to 47 dB with gradual temperature adjustment rather than abrupt cycling, and there are four fan speeds including auto. The ZAFRO app works with Amazon Alexa and Google Home, plus a 24-hour timer. A 61 to 86 degree range covers normal apartment comfort settings.

Fit and finish details

The window kit is universal for double-hung, single-hung and sliding windows, which is broader coverage than most kits manage. The remote reaches about 23 feet but is line-of-sight dependent, so test it from where the unit will actually sit. The main complaint in reviews concerns packaging damage on arrival rather than the product itself, so inspect the box before signing.

12. TURBRO Finnmark FM05K - Simple Starter Unit for Small Rooms

The TURBRO Finnmark FM05K is the simplest way to cool one small room in an apartment without overcomplicating the decision. It covers up to 300 square feet, installs in under 15 minutes with the full window kit, and several owners report cooling an entire small apartment with it when the apartment is genuinely compact.

The knob-and-LED control layout is unusual in this category and genuinely pleasant to operate, and the turbo function is useful when you walk in from a hot afternoon and want cold air immediately.

The remote is a real limitation

It requires a direct line of sight to the top of the unit and simply does not work if the AC is elevated on a stand or a shelf. That is unusual for a remote-controlled appliance and worth knowing before you choose a placement, because the control method effectively dictates where the machine has to sit.

Efficiency is the weak point

The SEER of 2.6 is the lowest figure in this roundup, and the 800-watt figure understates peak draw. Dehumidification is claimed at up to 43 pints per day, but reviewers report the included drain hose as poor quality and that a bucket still needs emptying without a dedicated drain line. For a small room used a few hours a day, that trade is defensible.

Setup note and airflow limits

Leave the unit upright for three to four hours after unboxing before the first power-on. Airflow can only be aimed straight or 45 degrees to the right, so orient the unit carefully rather than planning to swivel the louver.

How to Choose a Portable Air Conditioner for Your Apartment

A portable air conditioner moves heat from your room to outside, but it also pulls room air across a cold evaporator, chills it, blows it back, and expels the heat through an exhaust hose out a window. Understanding that loop explains most of the confusing differences between models. Here is what actually matters in a rental.

Dual-hose versus single-hose is the decision that matters most

A single-hose model uses one hose to draw room air in and vent hot air out at the same time. That means it exhausts some of its own intake, so the room gradually drops into negative pressure. Negative pressure pulls unconditioned air in through door gaps and window seals, so the unit works harder for less cooling, and in a sealed apartment the effect is much stronger than in a house with open hallways. Forum consensus across r/AirConditioners and r/hvacadvice consistently points renters toward dual-hose models for this reason.

A dual-hose model adds an intake hose that pulls fresh outside air for the condenser. The room pressure stays neutral, the condenser gets cold air to work with, and you get more cooling per watt. The cost is a wider window panel and a heavier machine.

Decode ASHRAE versus DOE BTU before you size anything

The ASHRAE figure is measured at the unit outlet, so it always looks generous. The DOE or SACC figure reflects sustained performance in a real room and is the more honest number for apartment sizing. An 8,000 BTU ASHRAE unit is roughly a 5,000 BTU DOE unit, and mixing the two standards is how buyers end up badly undersized.

As a starting point, allow about 20 BTU per square foot for a standard-ceiling room with modest sun, and add roughly 20 percent for a top floor, west-facing glass or heavy afternoon sun. That puts a 350 square foot room near 8,000 to 10,000 ASHRAE BTU, and a 500 square foot open-plan space closer to 12,000 to 14,000.

Match your window type or the unit is useless

Vertical slide and horizontal slide windows accept the standard bracket kits most models include. Casement and crank-out windows generally need a separate crank-window venting kit, which almost no buying guide mentions and which you should confirm exists for your frame before ordering. Sliding glass doors can usually be adapted with the included panel if the opening is wide enough. If you have no window at all, you are down to running the unit through a wall penetration, which most leases will not allow.

Noise: judge in decibels, not adjectives

Users in buildings with shared walls report that anything above roughly 55 dB becomes noticeable during sleep, and that 50 dB units can still trigger conversations with neighbors. Below 45 dB you are into genuinely quiet territory. This is why inverter compressors and acoustic isolation matter more in an apartment than the marketing language does, and it is the main reason the DREO 318S, Hisense and HUMHOLD stand apart.

Weight and stairs are an apartment-specific constraint

Most of these models fall between 40 and 61 pounds, and two exceed 80. A unit with casters and a recessed handle can be moved across a flat floor by one person, but stairs are a two-person job above about 55 pounds. In a walk-up, the 39.7-pound Antarctic Star is the honest answer; in a building with an elevator, weight matters much less and cooling capacity should take priority.

Running cost is a simple calculation

Take the wattage, multiply by hours per day, divide by 1,000 for kilowatt hours, then multiply by your utility rate. A 1,000-watt unit running eight hours a day for 30 days is about 240 kilowatt hours a month. A 1,450-watt inverter unit is roughly 350. The 3,520-watt Shinco is closer to 845 kilowatt hours a month for the same schedule, which is a real difference in a season rather than a rounding error.

When a portable AC is the wrong choice

A portable air conditioner cools one space. It will not cool a whole apartment, and running two in an open-plan room is usually less efficient than running one correctly sized machine. If you have a casement-only window, no permission to modify anything, and a need to cool more than one room, a window unit or a mini-split is the better answer and often the cheaper one over a few years. Portable units earn their place when you need flexible, room-by-room cooling, a renter-friendly no-drill install, or the ability to take cooling with you when you move.

If cooling has to travel with you rather than stay in one apartment, our guide to portable air compressors for cars covers the power side of that setup, and the power output of an overlanding compressor is the same calculation you would make on a job site.

Whichever you choose, clean the filter every one to two weeks during heavy use, keep the unit upright for several hours after any move, run the fan-only mode for a few hours after shutting down to dry the coils, and never ignore a musty smell. That last one is almost always a dirty filter or a wet coil, and it is the fix that prevents mold growth inside the unit. If you also plan to run tools or gear on the same circuit, our portable air compressor picks for overlanding are a useful companion reference.

Frequently Asked Questions

Which Portable AC Should You Buy for Your Apartment?

If you want one decision rather than twelve, take the SereneLife SLPAC8. Its 9.8 efficiency rating, 350 square foot coverage and 46.3-pound casted body cover more apartment situations than anything else here, and it is the pick we would put in a one-bedroom without further deliberation.

If noise is the deciding factor because you sleep next to a shared wall, the DREO 318S at 45 dB with drainage-free operation is the better buy. If efficiency over a full season matters more than anything, the Hisense HAP0824TWD pairs dual-hose design with an inverter compressor and a 15 efficiency rating, with the caveat that it carries a shorter Renewed warranty. For a large open-plan room, the HUMHOLD 16,000 BTU is the only one of these with the capacity, provided you accept the overheat cutoff in extreme heat.

For a walk-up with no elevator, the 39.7-pound Antarctic Star saves you a two-person carry. For a studio, the narrow Midea MAP05S1AWT-A with app and voice control fits the floor plan. And for the simplest possible solution in a small room, the TURBRO Finnmark does the job with fewer complications than anything else in the roundup.

Whichever one you choose, size it against the DOE number rather than the ASHRAE number, and check your window type before you order. Those two checks eliminate most of the disappointment people report in apartment AC threads.
