- Portable air conditioners are sometimes the only option to get the cool air you need, but they tend to be expensive.
- The LG 14,000 BTU Portable AC stands out from the crowd because it’s powerful, relatively quiet, and you can control it with an app or your voice.

Whether you endure hot weather all year long or only for a few months, when it is hot, humid, and sticky, air conditioning (AC) can become necessary to keep your home comfortable. To get the proper amount of AC, people often turn to portable air conditioners, which, like central and window units, can cool your house down.
Portable ACs are easy to move and install. In some cases, portable air conditions are the only option in homes or apartments where there is no central AC and window units are not allowed, or simply won’t fit. As an added bonus, out of all the types of air conditioners you can buy, portable units generally save you the most in your electrical bills.
Most portable air conditioners are broken into two categories based on their configuration: Single hose and dual hose.
- Single-hose AC units use the same hose as both intake and exhaust for air. While single-hose units will still cool the space you’re using them in, they will have to work harder to do so, meaning they are not as efficient as a dual-hose air conditioner. On the plus side, they tend to be cheaper and are a perfectly adequate solution for smaller rooms, such as a small bedroom or studio apartment.
- Dual-hose AC units have one intake hose and one exhaust hose. Because you have to two separate hoses, these types of portable air conditioner are usually more energy efficient, generally cooling a room approximately 40% quicker than single-hose units, and they are the preferred choice if you’re looking to cool a larger room.
All portable ACs come with window venting kits to help you ensure that the cold air stays in and the exhaust stays outside with all that heat. You’ll also need to look for ACs with self-evaporating technology that gets rid of the condensation produced by the unit. Otherwise, you’ll have to empty a tank regularly.
With portable units, you hear noise from the pumps, fans, and motors that make up the unit’s moving mechanical components. Since all portable AC units make some sort of noise, it’s just a matter of deciding how much noise is comfortable to you. Most manufacturers are continually making upgrades to decrease the noise level of their units and if it’s an especially quiet unit, this information will be a highlighted selling point in the product description.

The best overall
The LG 14,000 BTU Portable Air Conditioner can cool a 500-square-foot room with easy, runs quietly, works with Alexa and the Google Assistant, and you can control it from anywhere thanks to Wi-Fi support.
My living room, entryway, kitchen, and hallway are all somewhat connected, and in the summer, it all gets unbearably hot. It’s a fairly large space of about 500 to 600 square feet give or take. I’ve been using LG’s 14,000 portable AC to cool that big open space, and it makes a huge difference.
The AC was fairly easy to unbox and connect. I have a large window in my living room that has two smaller side panels that open and close, but the big section in the middle does not open. We had to saw part of the included window vent off to get it in the small window, but once that was done, it was easy to fit the cylindrical vent to the plastic window piece. You do have to click it in very firmly, so it’s good to have a helping hand when you do it.
To enable smart features like remote control via Wi-Fi and voice control with Alexa and the Google Assistant, you need to download the SmartThinQ app. It’s very easy to use, thanks to the simple interface. I had the AC connected to our Wi-Fi in about 10 minutes. After that, I could turn it on when I was on my way home to be greeted by a cool home or turn it on and off with my voice.
The remote control is also easy to use, and there are controls on the top of it, so if you aren’t into the smart aspect of the AC, you can still use it just like you would any other AC.
It runs quietly, thanks to LG’s Dual Inverter technology. LG says it runs at 44dB, which is 20dB quieter than the noise you experience in a car. Although I did not measure the decibels, I can confirm that it runs very quietly even when it’s cooling a large, hot space.
It has a sleep mode that you can set for 1 to 7 hours, which is a nice feature if you end up using it in your bedroom or just want it to turn off automatically after a set time.

The Whynter 14,000 BTU Dual Hose Portable Air Conditioner gives you full thermostatic control with temperatures between 61 and 89 degrees Fahrenheit. It comes complete with a digital readout, remote control, three fan speeds, a carbon air filter, and a washable pre-filter.

How many BTUs do you need?
How many BTUs do you need to cool your room?
When you’re shopping for portable AC units it’s best to prioritize the size of the area you wish to cool, rather than the size of the actual unit. To pick the most appropriate model, you’ll want to match the British Thermal Unit (BTU) requirements to the room size you plan to use it in.
BTU is the international measure of energy, and a BTU is the amount of heat needed to raise one pound of water by 1 degree Fahrenheit. When it comes to air conditioners, manufacturers use BTUs to indicate the quantity of heat a conditioning unit can remove from a room per hour. (One BTU per hour is equal to 0293 watts.)
As the BTU rating increases so do the weight, size, and cost of the air conditioner, but you have to make sure you get the right cooling capacity for your space. If you purchase a unit that has a higher BTU rating than the room requires, it will cycle off too quickly and won’t remove the humidity from the air properly. On the other hand, if you purchase a portable air conditioner that has a lower BTU rating than the room requires, it will run continuously and never cool the room adequately. Check out the breakdown below:
- A 150 sq. ft. room requires 5,000 BTUs
- A 250 sq. ft. room requires 6,000 BTUs
- A 350 sq. ft. room requires 8,000 BTUs
- A 450 sq. ft. room requires 10,000 BTUs
- A 550 sq. ft. room requires 12,000 BTUs
- A 700 sq. ft room requires 14,000 BTUs
