Portable Air Conditioners

Five vented units with both of their BTU numbers, and one machine that is not an air conditioner at all.

The job of this categorymoving heat out of a window, honestly measured. Every listing below is read against that, and the badges go to the ones that answer it most directly.

A portable air conditioner does not make cold. It moves heat from inside the room to outside the room, and the hose going out of the window is the entire mechanism. Everything about buying one follows from that.

The other thing that follows from it is the two BTU numbers. The bigger figure on the front of the box is measured one way; the smaller figure in the specifications is measured another. Both describe the same machine. The smaller one is the figure that lines up with room area.

The last unit on this page is an evaporative personal cooler. It is not an air conditioner, it publishes no BTU figure, and it is kept in its own group so nobody buys it expecting the room to get cooler.

The exhaust hose goes out of a window, always

The hot air a portable unit removes has to leave the building. That is what the hose is for. Venting it into the same room, into a closet, into a drop ceiling, or into any other enclosed space defeats the machine entirely and puts heat back where it came from.

The hose gets hot in normal operation. Keep it clear of bedding, curtains, and anything that should not be in contact with a warm surface, and keep the run as short and straight as the window position allows.

If a room has no window the hose can reach, a portable air conditioner is not the answer for that room. An evaporative cooler is not a substitute for it either — that machine works on a different principle and does not remove heat from the space.

Two BTU numbers, one machine

ASHRAE and SACC are two different test methods, and a portable unit carries a number from each. The ASHRAE figure is larger and appears in the product name. The SACC figure, which the Department of Energy test produces, is smaller and appears in the specifications.

On some units in this catalog the gap between the two is close to half. That is why room area should be matched against the SACC figure. Any square footage stated in a listing is the seller describing the product, not a calculation for your room.

How this page is orderedVented units are ordered by how completely the listing states its numbers, starting with the one that gives both BTU figures. The evaporative cooler is listed last and is not ranked against them, because there is no shared figure to rank on.

Vented portable air conditioners

Heat leaves through a hose in a window. Each listing states a headline BTU figure and a smaller measured one.

Both BTU numbers stated
DREO 515S Portable AC, 12,000 BTU ASHRAE

DREO 515S Portable AC, 12,000 BTU ASHRAE

  • 12,000 BTU ASHRAE
  • 8,000 BTU SACC

This is the unit that puts both numbers where you can see them: the listing states 12,000 BTU ASHRAE in the name and 8,000 BTU DOE in the details. Those are the same machine measured two ways, and the smaller one is the figure that gets compared against room area. The listing also states drainage-free cooling plus fan and dehumidifier modes.

What the listing supports, and what it does not
  • Carries the ASHRAE figure and the DOE figure in the same listing, so nothing has to be guessed at
  • The listing states drainage-free cooling, which is the part people ask about after the first humid week
  • Fan and dehumidifier modes are stated, so it has something to do in shoulder season
  • App and voice control are stated for people who already run other connected gear
  • The listing does not state a room area, so there is no seller figure to sanity-check against
  • Still needs a window the exhaust hose can reach, like every vented unit here
  • Connected features mean a network setup step before it will do anything remotely

Best forSomeone comparing boxes and trying to work out which BTU number to trust.

Largest stated SACC
Midea Duo Portable AC, 14,000 BTU

Midea Duo Portable AC, 14,000 BTU

  • 14,000 BTU ASHRAE
  • 12,000 BTU SACC
  • 550 sq ft stated

The largest SACC figure in this catalog: the listing states 12,000 BTU SACC behind a 14,000 BTU headline, and puts room coverage at up to 550 sq ft. The listing also states an inverter compressor plus smart and remote control. The gap between the two BTU numbers here is narrower than on most of the other units, which is itself worth noticing.

What the listing supports, and what it does not
  • The listing states 12,000 BTU SACC, the highest stated SACC figure in this catalog
  • The stated 550 sq ft coverage is the largest seller figure among these units
  • An inverter compressor is stated rather than a fixed-speed one
  • Smart control and a physical remote are both stated, so the panel is not the only way in
  • The stated area is a seller figure, not a calculation for your particular room
  • Bigger units are heavier to move between rooms and take a wider window opening
  • Two BTU numbers on one box still confuses shelf comparisons against smaller units

Best forThe largest room in this catalog that still has a window the hose can reach.

Kit named in the listing
Shinco Portable AC, 12,000 BTU

Shinco Portable AC, 12,000 BTU

  • 12,000 BTU ASHRAE
  • 7,500 BTU SACC
  • 450 sq ft stated

A 12,000 BTU headline with a stated 7,500 BTU SACC underneath it, which is a wider spread than the Midea Duo carries. The listing states rooms up to 450 sq ft, a 24 hour timer, and an installation kit in the box. The kit matters because the window hardware is what actually decides whether a portable unit can be set up the day it arrives.

What the listing supports, and what it does not
  • An installation kit is stated as included, so the window side is not a separate errand
  • A 24 hour timer is stated, which covers running it only while a room is occupied
  • Both the headline BTU and the SACC figure appear in the listing
  • The stated 450 sq ft sits between the largest and smallest units here
  • The spread between the 12,000 headline and the stated 7,500 SACC is wide enough to mislead at a glance
  • The stated area comes from the seller and assumes nothing about ceiling height or sun
  • A window kit that ships in the box still has to match the window you actually have

Best forA first portable unit where the window hardware needs to arrive with the machine.

BLACK+DECKER Portable AC, 9,000 BTU

BLACK+DECKER Portable AC, 9,000 BTU

  • 9,000 BTU ASHRAE
  • 5,300 BTU SACC
  • 400 sq ft stated

A 9,000 BTU headline over a stated 5,300 BTU SACC. The listing states rooms up to 400 sq ft and describes a 3-in-1 arrangement with fan and dehumidifier modes. Read against the Shinco, this one advertises nearly the same room area from a considerably smaller stated SACC figure, which is exactly the comparison the ratings pages exist for.

What the listing supports, and what it does not
  • Fan and dehumidifier modes are stated, so it has a job outside peak summer
  • Smaller stated SACC means a smaller, more movable cabinet
  • The listing gives both the headline number and the SACC number
  • A stated 400 sq ft coverage figure is available to compare against other listings
  • The stated 400 sq ft sits on a 5,300 BTU SACC figure, so compare that pairing carefully
  • Almost half the headline number disappears when the SACC figure is read instead
  • Still requires a window exhaust route, the same as every vented unit

Best forA smaller room where the dehumidifier mode gets as much use as the cooling.

Midea Portable AC, 8,500 BTU ASHRAE

Midea Portable AC, 8,500 BTU ASHRAE

  • 8,500 BTU ASHRAE
  • 5,000 BTU SACC
  • 150 sq ft stated

The smallest vented unit in the catalog and the most internally consistent one: the listing states 8,500 BTU ASHRAE, 5,000 BTU SACC, and up to 150 sq ft. That stated area is well under what the other listings claim from similar SACC figures, which reads as a more conservative seller figure rather than a weaker machine.

What the listing supports, and what it does not
  • The stated 150 sq ft is the most conservative coverage figure among these listings
  • A window kit is stated as included
  • Smallest stated SACC in the catalog, which suits a single small room
  • App and remote control are both stated
  • The stated 150 sq ft rules it out for the open-plan rooms the larger units advertise
  • The ASHRAE headline is still 70 percent above the stated SACC figure
  • Small cabinet or not, the exhaust hose requirement does not shrink with it

Best forOne small bedroom or a home office with a single window.

Evaporative personal cooler — not an air conditioner

Evaporates water to move air past one person. No BTU figure exists for it, and it adds humidity to the room.

Evapolar evaCHILL Personal Evaporative Cooler

Evapolar evaCHILL Personal Evaporative Cooler

This is a personal evaporative cooler, and the listing says so plainly. It is not an air conditioner. It publishes no BTU figure, it does not move heat out of the room through a hose, and it works by evaporating water, which puts moisture into the air instead of taking it out. It sits in this catalog in its own subgroup so nobody reaches for it as a substitute for a vented unit.

What the listing supports, and what it does not
  • The listing is explicit that this is an evaporative cooler and fan, not an air conditioner
  • No exhaust hose and no window requirement, because it is not moving heat outdoors
  • Sized for a desk, an office corner, or a car according to the listing
  • Nothing to install, which is the entire point of the format
  • It does not cool a room, and no BTU figure exists to compare it with the vented units
  • It adds humidity to the air, which is the wrong direction in an already damp room
  • Evaporative coolers depend on the surrounding air being dry enough for water to evaporate

Best forAir movement at one desk, where nobody is expecting the room temperature to change.

Questions this category gets asked

Which BTU number should I use to pick a size?

The smaller one — the SACC or DOE figure in the specifications. The headline ASHRAE number in the product name is measured under different conditions and reads considerably higher for the same machine.

Can I vent the hose into another room or a closet?

No. The heat has to leave the building. Venting into any enclosed indoor space puts the heat back into the house and stops the machine doing the one thing it is for.

Is the Evapolar evaCHILL an air conditioner?

No. It is an evaporative personal cooler and a fan. It publishes no BTU figure, it does not remove heat from a room, and it adds humidity to the air rather than removing it. It is listed here in its own group for exactly that reason.

What does the stated square footage on a listing mean?

It is a figure the seller publishes about the product. It does not account for ceiling height, insulation, how many people are in the room, or how much sun the windows get. Treat it as one input, not as a result.

My room has no window. What are my options?

Not a portable air conditioner, and not an evaporative cooler as a substitute for one. Options that move heat out of a building need a route out of the building, and finding one for a windowless room is a question for a licensed HVAC professional.
