A primary measure was seasonally adjusted cooling capacity, or SACC , a US Department of Energy calculation that represents the weighted average performance of a portable air conditioner in a number of test conditions. In , the Department of Energy also finalized new standards for combined energy-efficiency ratio CEER , a new metric based on SACC that considers additional factors such as standby energy usage alongside the previously used energy-efficiency ratio EER measurement.
When in doubt, consult the EnergyGuide label on the box. The main risk of using an oversize AC is overcooling the area before dehumidifying it, and all of these units have dehumidifier functions that can remove moisture without chilling the space if a room gets too cold and clammy. But we were more concerned about making recommendations that could actually provide adequate power.
Those results helped our decision to go big and not focus too much on the claimed square-footage requirements. With our performance needs met, we gathered a half dozen finalists and evaluated them in person, looking for the following factors:. Our initial performance requirements for our testing narrowed the field of portable ACs to 23 promising models, and after applying our remaining criteria, we settled on five finalists to call in for testing.
Our research, however, ultimately steered us toward single-hose portable models—in part because so many newer models use this design. In fact, we found no compelling new double-hose models from major manufacturers in or although a few new ones cropped up in , including our new top pick.
The one major exception, however, is if you plan on setting up your portable AC in a room with a furnace or hot water heater or anything else that uses combustion. When a single-hose AC model forces air out through its exhaust hose, it can create negative pressure in the room.
In the presence of a gas-powered device such as a furnace, that negative pressure creates a backdraft or downdraft, which can cause the machine to malfunction—or worse, fill the room with gas fumes and carbon monoxide. Over the course of a sweltering summer week in Boston, we set up our five finalists in a roughly square-foot space, taking notes and rating each model on the basic setup process, performance, portability, accessories, and overall user experience.
The makers of portable air conditioners are required to list their performance and efficiency statistics, and our research and our previous testing have proven these numbers to be accurate. By prescreening for these stats, we got the impression that every model we tested would cool a room capably. We confirmed that they did by taking measurements with two Lascar temperature and humidity data loggers —we placed one 3 feet away, directly in front of the unit, and placed the other one 6 feet away on a diagonal.
We gauged the overall quality of the sound and noted any spikes in any frequencies that registered in the app. As we set the units up, rolled them aside, switched from one to another, and fiddled with their vent-hose attachments in the window, we learned a lot about which ones we would get for ourselves or recommend to friends. The Duo is one of the rare portables with a variable inverter compressor, which allows for more fine-tuned and energy-efficient temperature control.
This detail, combined with the wide variety of window-installation panels that Midea includes in the box, makes the Duo especially easy to wrangle and install a particularly remarkable feat for a dual-hose model. If you have to live with a portable AC in the room, this is the coolest roommate you could ask for. In our tests, it produced some of the most even and consistent cooling across the room, never registering more than a 1-degree difference between our monitors positioned at 3 feet directly in front of the AC and 6 feet away on a diagonal.
But according to the more comprehensive SACC performance standards, which measure across conditions, it achieves an impressive 10, Btu per hour. By contrast, the other models we tested reached SACC scores between 7, and 8,, even with a higher Btu rating by the old standards although that also demonstrates some of the problems with those older measurements. The low and medium fan settings are remarkably quieter 45 dB and 48 dB, respectively than the high setting 56 dB ; as a result, the compressor is much more noticeable when it kicks on with the lower fan settings than when the whole thing is running on high.
In fact, with both the compressor and the fan on high, we had trouble measuring any volume difference at all. The compressor did produce a fuller sound than the fan-only setting, especially on the lower end of the spectrum. The only exception to this trend was one of our also-great picks, the Frigidaire Gallery Cool Connect GHPCAB1, which surprised us with measurements about 1 or 2 decibels quieter than what the Midea model produced, despite its use of a standard non-inverter compressor.
In our tests, we measured the temperature from 3 feet directly in front of the AC and 6 feet away on a diagonal, and the Duo was mostly able to retain a consistent temperature within 1 degree between those two thermometers. After all, cold air is heavier than warm air and thus tends to sink to the ground sooner. But the Duo was able to send those initial gusts of air far enough to ensure that the cold air actually spread before it sank.
Anecdotally, we could feel that physical difference in the room, too. This design is easier to manage than the hoses on other models we tested—some project awkwardly out of the back, sit perpendicular to the unit, or are completely detachable so they must be stored separately and can be misplaced. Suffice to say, the Midea Duo is more likely to have the hardware that you need for your particular situation, whatever it may be.
Like the other models we tested, the Duo allows you to set it to dehumidify without cooling or just run it in a fan-only mode. Its drain port works like the others, as well: You can screw it open when you need to empty the unit of condensation or attach a hose to it.
Note, too, that this drain is higher up on the Duo than on other models—about 1 foot up from the bottom, which should make it easier to tilt and drain. Also like other portables, the Duo uses filters that are easy to remove and clean without any additional tools. The remote control is standard, and the unit has a convenient recess on the back to store the plug at the end of the season.
The Duo also has smart capabilities that allow you to control it via a smartphone app, Amazon Alexa, or Google Assistant. We appreciated that the Duo could function fully without relying on the app or the voice controls, but we valued this versatility, especially for anyone who has difficulty getting up and manually adjusting the unit itself.
At 73 pounds, the Midea Duo is one of the heavier portable ACs out there—about 5 pounds more than our budget pick and more than 10 pounds heavier than the convertible dual-hose model we tested from GE. The caster wheels and handles make it easy enough to move around on flat areas.
It also has all the same smart-home features though with a different user interface , a similar built-in accordion hose and sturdy window-installation kit, and a convenient pocket on the back where you can store the remote control, plug, or manual. The LG sounds similar to the Midea, too, with a pop-up fan that makes a gentle, almost breath-like white noise.
Some owner reviews complain that the compressor on the LG emits a loud, high-pitched whine that sometimes makes sleeping difficult. The Frigidaire also cooled faster at the beginning of the cycle, dropping the temperature about 2. And the Frigidaire was better than any other model we tested at maintaining a consistent temperature between the two sensors we placed in the testing room one at 3 feet directly in front of the AC, and the other 6 feet away on a diagonal , spreading the air evenly around the room so that there was never more than a half-degree difference.
But its volume output came as a similar surprise, as it measured about 2 decibels quieter on average than the Midea. Like the other models we tested, the Frigidaire has a drain plug, a washable filter, and mostly seamless smart-home capabilities. However, the LED indicators—including the optional Quick Glance Light, which lets you know when your room has reached your target temperature—were a little too bright for our tastes.
Although the hose has some nice touches such as a lattice over the exhaust port and a nice cloth sheath to dress up the otherwise unsightly plastic accordion tube, this model also came with the least modular window-panel options. We had to snap one of the plastic plates in half in order to fit it snugly into a standard double-hung window. This is great if you think you might enjoy listening to an amateur White Stripes cover band with a snake on lead vocals, but it might not be the best if you want to sleep or get any work done.
At It has rough, bumpy casters that felt cheaply made to us but work well enough. The Honeywell MN4HFS9 is another new model we plan on looking at, which offers heating capabilities as well as cooling.
