The Midea 6,000 BTU portable air conditioner is a good unit to use in small rooms. We were impressed by its 3-in-1 functionality, which can cool, dehumidify and circulate air when necessary.
Our testing was characterized by the quiet operation of the unit. It was also whisper-quiet, even at high settings, which is why it is perfect to use in bedrooms or home offices. The sleep mode also lowered the noise levels, thus providing a peaceful sleep.
It was easy to install, and it took me only a few minutes to install it using the provided window kit. The LED screen and the remote control made it convenient, and it was easy to change the temperature and mode across the room. We also liked the filter that can be removed and washed easily.

We were impressed with the various operating modes. We liked the fact that we could alternate between cooling, fan and dehumidifying modes. The auto-swing air vent worked very well in circulating cool air in the room.
Although the AC worked well, we observed that it is a little bit noisy when in use. This could be a problem to light sleepers. Nevertheless, this LG portable AC is a good value to people who require portability in cooling.

LG Portable AC
Although it has certain performance issues, we recommend this LG portable air conditioner because of its flexibility and simple installation.
Pros
- Convenient installation and storage
- Convenience by remote control
- 3-in-1 functionality
Cons
- Unstable cooling ability
- Possible overheating problems
- Small coverage area
The LG LP0524WFR was a mixed bag to us. Its small size and easy installation are sure advantages. The remote control makes it more convenient as we can change settings even when we are in the other side of the room.
The 3-in-1 feature was impressive. We liked the cooling mode on hot days, the fan mode to circulate air and the dry mode to use in humid conditions. The auto-swing mode spread the cool air in our small area.
Unluckily, we had a few cooling discrepancies. It was annoying that the unit sometimes switched off without warning. Although it is appropriate in rooms that are as small as 150 square feet, we discovered that it does not perform well in bigger rooms.
Small Window Air Conditioner Buying Guide
The most important consideration when buying a 5000 or 6000 BTU AC is that it has enough cooling power for your space.
That’s the theme of this buying guide.
5000 BTU & 6000 BTU Window Air Conditioners Pros & Cons
They definitely have their advantages and disadvantages.
Pros:
- Allow you to cool a very small room without overdoing it – Cool air is nice; being cold isn’t cool. That’s what you’ll get when a 6000 BTU unit will do but the AC is a 12000 BTU model.
- Fit small windows that won’t accommodate a larger AC.
- Cost is often lower than for window ACs with higher BTU cooling capacity.
- They’re quieter than larger units.
Cons:
- They won’t effectively cool 150 or 250 square feet if the space is especially warm. The next section covers this topic in more detail.
- Some of the smallest units are junk – but none of those units are on our list.
Sizing your Window Air Conditioner
Keep in mind that a 5000 BTU AC is rated for “up to” 150 square feet and a 6000 BTU unit is rated for “up to” 250 square feet.
In simple terms, that a room 10×15 (150 square feet) or about 15×17 (about 250 square feet).
Those are the biggest areas these units can effectively cool and dehumidify.
“Does the room have factors that make it harder to cool?” If so, you’ll need a bigger AC.
Add 1000 BTUs of required capacity for these factors:
- The room faces west, south or both
- The room adjoins non-cooled, enclosed space like an attic or garage
- The room has 9-foot ceilings
- The room has 10-foot ceilings (add 2000 BTUs)
- The room is on an upper floor
- The room is a kitchen
Here are two sample scenarios:
#1: A 150 square foot bedroom (5000 BTU) faces west (+1000 BTU) and is on the second floor (+1000 BTU). It has attic space adjoining one side (+1000 BTUs).
This room really needs an 8000 BTU window AC. A 10000 BTU model wouldn’t be oversized if it had Low Cooling mode.
#2: A 250 square foot kitchen (6000 BTU) has 10-foot ceilings (+2000 BTUs), faces south (+1000 BTU) and adjoins an enclosed garage that gets really hot on summer days (+1000 BTUs).
This kitchen needs a 10,000 BTU window AC, and a 12,000 BTU model probably would be handy on the hottest days when the stove or oven is in use.
