              How To Choose The Best Portable Air Conditioner For Bedroom?

              Size & BTU

              When we talk about choosing the right size, we talk about BTU or British Thermal Units. It’s important to fully understand what it is.

              BTU is the amount of energy required for raising the temperature of 1 pound of water by 1-degree F at sea level. A product with a higher BTU’s amount will remove heat from a larger room at a certain rate, cooling the entire room down.

              Avoid Too Little or Too High BTU

              While a higher BTU rating means faster cooling, it doesn’t mean you should choose the highest BTU rating. A too-high BTU rating for a small room will cause the unit to cool quickly, but it will cycle off and then back on, over and over again to keep your room at the set temperature.

              As a result, the air conditioner won’t remove humidity from the room. It will be overworked, consume more electricity, and you will have a room with excessive humidity.

              Meanwhile, too-low BTU rating for the room means the air conditioner will run its cycle non-stop and it will be overworked too. The result is a hot room with large electricity consumption.

              How to Know the Right BTU Rating?

              It’s not easy to figure out the accurate needed BTU rating, but youcan still choose the right BTU range for your room. According to the standard rule, for each square foot of floor space, you need 20 BTU.

              So, first, multiply the width of the room by its length, both of which in feet. Then, multiply the result by 20 and you will have the appropriate BTU rating for your room.

              For example, a 300-square-feet room or smaller will need 10,000 BTU, a 500-square-feet room will need 10,000-14,000 BTU, while a room larger than 500 square feet will need over 14,000 BTU.

              Factors Affecting the BTU Rating

              The right BTU rating may vary depending on several factors as the following:

              • If the room is taller than 8 feet, raise the BTU amount by 10% for each foot.

              • If the room is shaded heavily, reduce the BTU amount by 10%.

              • If the room in sunny with a lot of sunlight entering, raise the BTU capacity by 10%.

              • If there are three or more people in the room, you should add 600 BTU for each person in the room.

              • If there are a lot of heavy appliances for use in the kitchen, you should increase the BTU rating by 4,000 BTU.


              Air conditioners make noises when they operate, which can be considered “background noise.” While this continuous noise doesn’t seem considerable during the night, it can interfere with your sleep at night.

              According to WHO, measurable sleep disturbance effects begin at the noise of 30 dB LAeq. Therefore, you should look for an air conditioner that produces noise lower than this level.

              Other Features

              • Programmable Thermostat: allows for setting an exact temperature for the room, at which the air conditioner will turn off automatically.
              • Remote Control: allows for controlling the air conditioner from a distance without having to stand up and touching the machine.

              Which Brands Make The Best Portable Air Conditioner For Bedroom?


              With the aim of refining your life, the brand offers products to help you sleep comfortably at night during the hot summer.


              With over 100 years of experience, Honeywell has set its footprint in several sectors, including aerospace, building tech, safety & productivity solutions, performance materials & technologies.


              This brand is best known for making affordable, good home products. It offers various portable air conditioner models with varying BTU rating.


              Founded in 1968, in China, Midea is the world’s largest manufacturer when it comes to household appliances. It offers both commercial air conditioners and consumers’ air conditioners.


              Over the past 28 years, SHINCO has made itself one of the largest air conditioner manufacturers in China, setting its foot in other markets like the US, the UK, and Australia.


              Can I use a portable air conditioner in a room without a window?

              How many BTU do I need for a 12x12 room?

              You can easily calculate the needed BTU rating for a 12x12 room using the guideline we provided. In this case, a 12x12 foot room is 144 square feet, meaning you will need 7,500-10,000 BTU.

              Do portable air conditioners waste a lot of electricity?

              Generally speaking, a portable air conditioner is less energy-efficient than a window unit. For instance, a 10,000 BTU window unit can cool down a 450-square-foot room, but a 10,000 BTU portable unit can cool a 300-square-foot room only.

              How can I make my portable air conditioner more efficient?

              There are several things you can do to increase your portable AC’s efficiency:

              • Choose the right portable air conditioner.

              • Place it in the right place, avoid direct heat and light sources.

              • Vent the AC properly.

              • Clean the air filter

              • Store the AC properly.

              Is it cheaper to use a portable air conditioner?

              In certain situations, using a portable air conditioner is cheaper because it may use just 1/8 the electricity as the central air conditioner. But keep in mind that this is different from the energy efficiency we mentioned above, and a portable air conditioner can cool a small room only.


              When it comes to choosing the best portable air conditioner for bedrooms, the one thing you need to keep in mind is the BTU rating, which is directly related to the needed size of the air conditioner.

              It’s not easy to pick out the perfect portable AC for your bedroom, but once you know what and where to look, you will be able to finalize on one.

              And we hope that our guideline will bring you to the smart decision faster.
