To help you find the best air conditioners, we spent over 15 hours of research compiling a list of the best air conditioner models on the market today. We looked for both portable and window-mounted systems, capable of at least 5000 BTUs — enough to quietly cool up to 150 square feet of space. We also looked for units that were relatively low-maintenance with reusable filters and gave bonus points to ones that had additional features, such as a dehumidifier to remove moisture.
Our top pick for the best air conditioner is the hOmeLabs 14,000 BTU Air Conditioner, which earned the title because it’s the best all-around unit on the list. The BTU rating of 14,000 can cool up to 500 square-feet efficiently. Moreover, it has a built-in dehumidifier, includes a remote control, and also a washable filter. Our honorable mention is SereneLife 8,000 BTU Portable Air Conditioner. It’s slightly cheaper (and less powerful) than the top pick yet includes a lot of the same features. Of course, there are several other options. Keep reading to learn more about our top picks.
Top 7 Best Air Conditioners
#1 hOmeLabs 14,000 BTU Portable Air Conditioner
Award: TOP PICK
WHY WE LIKE IT: The hOmeLabs air conditioner has a 14,000 BTU rating, which covers about 450 to 500 square feet. That’s a sizable area for a portable AC, and when you consider everything else it has to offer.
Read Full Review: hOmeLabs 14000 BTU Portable Air Conditioner Review
- Most feature-rich & dehumidifier
- Includes remote control
- The dehumidifier removes 100 pints per hour
- Still needs to be close to a window
Standing at 30-inches tall, the hOmeLabs Portable Air Conditioner offers a 14,000 BTU rating. It’s capable of cooling spaces up to 450 square feet. It’s a floor-based unit, so you don’t have to mount it in a window. Built-in wheels make it rather easy to move from room to room. You will need to install a window slide adapter and connect a hose, but other than that setup is straightforward and installation costs should be relatively low. It has a washable filter, so you don’t need to buy replacements. Furthermore, it comes with a remote, which allows you to configure the unit from afar.
A built-in 100-pint dehumidifier offers moisture and humidity controls if you need them. It adds a lot more value in places where humidity is high. It might also be useful if you install the unit in a much smaller space than intended. Compared to the other air conditioners on the list, the hOmeLabs unit is one of the most expensive. Even so, it’s the best AC option if you want energy efficient cooling for a decent-sized area and don’t like traditional window-mounted units. If you want to dry a room on the other hand, the best drying fan will help.
#2 SereneLife 12,000 BTU Portable Air Conditioner
Award: HONORABLE MENTION
WHY WE LIKE IT: We chose the SereneLife 8,000 BTU Portable Air Conditioner for honorable mention because it offers a lot of the same excellent features as the top pick, albeit at a more affordable price.
Read Full Review: SereneLife 12000 BTU Portable Air Conditioner Review
- Excellent features, great price
- The dehumidifier removes 3.8 pints per hour
- Touch-button control panel with LED display
- Still needs to be close to a window
Like our top pick, the SereneLife 8,000 BTU Portable Air Conditioner is a standing unit at 32 inches tall. It also has wheels so you can roll it from room to room. It still needs to sit close to a window and comes with a window plate and exhaust vent to expel warm air. SereneLife claims the unit can circulate cool air around an area up to 225 square feet. That’s a decent-sized area for a portable unit. It has three operating modes, including a standard AC cooling mode and a fan-only mode. The third is a dehumidifier which will remove moisture and humidity. It does come with a remote, but there is a touch-button control panel on the top with a digital LED readout display, as well.
The price is average, but overall a little higher than most of the other units on this list. Keep in mind, a majority of the other units are less powerful, nor are they upright like this one. If you don’t want a traditional window AC unit and want something that can easily be moved around your home, the SereneLife air conditioner is a good choice. It’s also slightly cheaper than our top pick yet has a lot of the same features if you’re on a tight budget. Rather than relying on a portable, window-mounted or central AC, you could also cool a room with the best large ceiling fans.

Read Full Review: TOSOT 8,000 BTU Window Air Conditioner Review
- Sleek, minimalistic visual design
- Thermostat built into the remote
- Washable, reusable filter
- Window units can be unsightly
The TOSOT window-mounted air conditioning unit offers 8,000 BTUs, which is enough power to efficiently cool up to 300 square feet of space — TOSOT claims up to 350 square feet. What’s most striking about the unit, however, is that it’s sleek and employs a minimalistic design. Instead of the rather ugly metal grilles of similar units, it has low-profile vents especially when everything is sealed up. A built-in dehumidifier means the unit will cool and remove humidity from a space. A built-in reusable filter can be cleaned, so you don’t have to replace it regularly, just clean it. Furthermore, the system offers smart temperature controls with the thermostat on the remote — not the actual unit. That means the unit will cool the space based on the temperature that the remote picks up.
Because the TOSOT air conditioner does need to be installed in a window, it comes with everything you need, including side panels. You will need a space of about 23 to 36 inches wide, and 15 inches tall.
How We Decided
The most important feature is the BTU rating or power and efficiency rating of the unit. It tells you how much space the unit can cool efficiently, informing precisely what size you need. Furthermore, it gives you some idea of how well the machine might cool a room or space. We looked for anything at least 5,000 BTU or above, enough to cool up to 150 square feet.
The next thing we looked for was the degree of operation each unit offers, or rather how many operating modes they have. Every unit on the list has several operating modes for both the cooling and fan. Most of the units include an additional mode thanks to a built-in dehumidifier, which helps to remove moisture and humidity in a space. Operating noise is also a concern, especially at night when you’re trying to sleep. The Black & Decker BPACT14WT portable air conditioner is not only one of the quietest, but it also includes a stealth mode for nighttime use. All other air conditioners, however, do run relatively quiet, and several also include a similar low-power sleep mode.
Almost all of the air conditioning units on the list have to be installed near a window or open space, including the floor-based units. That’s because the warm air is vented through an exhaust pipe that, hopefully, leads outside. Everything you see on the list includes all the necessary mounting accessories you will need to install and set up the unit. That includes the exhaust vent or pipe, and window panels.
Finally, we looked at the size of each unit. Believe it or not, there’s a standard size range for window units, which is less of a concern with portable and standing units. All the window units on the list fit in the range of 20 to 38 inches for width and 13 to 16 inches for height. That range allows for optimal compatibility with modern window frames.
Best Air Conditioners Buyer’s Guide
The Most Important Features to Consider
- Power and Efficiency (BTU)
One of the most important specifications to consider when choosing a portable or window-mounted air conditioning unit is the power and efficiency at which it operates, denoted in BTUs or British Thermal Units. Generally, the higher the number the faster and more efficient heating and cooling will be in the affected space or room. That said, choosing a unit with a higher number isn’t always better. You should be choosing a unit based on the amount of space you need cooled or heated. A unit that’s too powerful will consume inordinate amounts of energy, raising costs. Not to mention, when a unit is too strong it can have adverse effects on the climate. For example, a more powerful unit will almost always raise the humidity in the space, sometimes even making it much too humid or clammy.
- Coverage Area
For the products that list the total coverage area in square footage, it’s vital to choose an adequate unit. Our top pick, the hOmeLabs 14,000 BTU Portable Air Conditioner, explicitly states that it can cover 450 to 600 square feet of space. True coverage is definitely closer to the lower range, by the way. When that’s not available, however, you can infer the coverage area by looking at the BTU rating. Here are the recommended square footage ranges for each BTU rating:
- 5,000 BTU – Up to 150 sq. ft.
- 6,000 BTU – 150 to 200 sq. ft.
- 8,000 BTU – 250 to 300 sq. ft.
- 10,000 BTU – 300 to 350 sq. ft.
- 12,000 BTU – 350 to 400 sq. ft.
- 14,000 BTU – 400 to 450 sq. ft.
- 15,000 BTU – 450 to 500 sq. ft.
- 18,000 BTU – 500 to 600 sq ft.
- 20,000 BTU – 600 to 700 sq. ft.
- 22,000 BTU – 700 to 800 sq. ft.
- 25,000 BTU – 800 to 900 sq. ft.
It’s best to choose the correct size for the area you want heated or cooled. Choosing a unit with less power means it won’t be effective if it is at all. Choose a unit that’s too powerful and you’ll experience an adverse climate such as higher humidity levels.
- Mounting Accessories
When you are looking for an AC unit for your home, make sure that whatever model you choose comes with all the necessary mounting accessories. If you get a unit that doesn’t include them, it’s going to be extremely difficult to find panels to fit in the open space of the window the unit creates. The panels must be a suitable size, matching the precise dimensions of the AC unit.
For window units, our best window air conditioner guide has some good choices. If you are looking for something smarter, check out the best WiFi smart air conditioner. However, those larger units are not for everyone. That’s why you can read the best small portable air conditioner.
Those who live the Rv lifestyle also have air conditioning choices with the best RV air conditioner.
Air Conditioners FAQs
Which Is the No. 1 AC in the World?
What constitutes “best” is going to vary from person to person, so be sure to consider the top features and brands and make a selection based on your needs. That said, if we had to choose the best window air conditioner or best portable air conditioner then it would have to be the top pick, hOmeLabs’ 14,000 BTU Portable Air Conditioner. It’s the best all-around unit on the list, with an incredible BTU rating — enough to cool up to 500 square feet of space. It also includes a lot of excellent features such as a built-in dehumidifier, washable filter and even a remote control. If you’re looking for something cheaper, you can’t go wrong with the SereneLife 12,000 BTU Portable Air Conditioner, which earned our “honorable mention” title. It has a lot of the same features as the hOmeLabs top pick but at a more affordable price.
Who Makes the Best Central Air Conditioner?
Central air conditioning units are much different than portable and window-mounted air conditioners. They are meant to cool an entire home, residence or building as opposed to a single room or small space. They use much more power and are, understandably, way more expensive. Unlike portable or window air conditioners, you can’t install a central air conditioning unit on your own either, they need to be installed by a licensed professional. Some of the best central air conditioner brands 2019, include Trane/American Standard, Maytag, Carrier/Bryant, Daikin, Goodman, Heil and Mitsubishi.
How Do I Choose a Good Air Conditioner?
What you want to look at when choosing the best portable air conditioner is the BTU rating, or power and efficiency rating. It will explicitly tell you how much space the unit is capable of cooling or heating efficiently. It’s important to select a unit that matches the size of the room where you’re going to install it. Choosing a unit that’s too big will create excess humidity while choosing a unit too small will result in ineffective cooling.
What Does BTU Mean?
BTU stands for British Thermal Unit and refers to the unit of measurement that commonly denotes the efficiency of heating and cooling systems. 1 BTU — or a single unit — refers to the total energy necessary to heat or cool one pound of water by an increment of 1 degree in Fahrenheit at sea level. The best portable air conditioner models operate in the range of about 8,000 to 12,000 BTUs. Split system air conditioners operate around 9,000 to 36,000 BTUs. Finally, some of the best window air conditioner units operate in the range of 3,000 to 25,000 BTUs. Larger central air conditioning systems and units are given different measurements, generally in tonnage. Converting between BTUs and tonnage is rather simple. 1 air conditioner ton is the equivalent of 12,000 BTUs per hour.
