Even though you might, do not be tempted to get a unit that is too big, because if you do, then your room could end up being cooled to quickly. This means the unit could end up being turned off before it even has the chance to remove a lot of moisture from the air. Also, some units have other functions, such as a heater or even a dehumidifier.
Here are what we think is the best portable ac for big rooms.
Our pick is the NewAir AC12000E 12,000 BTU Portable Air Conditioner, which is 12,000 BTU and it can cool down a hot room that is around 300-425 square feet. You can set the temps between 64-90 degrees Fahrenheit, and it features a programmable timer.
However, one of the cons is that it is noisy. In matter of fact it is one of the loudest ac units that we have reviewed. Even though it is loud, many customers have said it is still worth getting because of how good it can cool down a room.
Another AC unit worth looking at is the EdgeStar API200S, as it is very reliable and will likely last you for many years. It features a 3M carbon filter, a programmable timer, as well as a dehumidifier.
It is a large unit, and it has high ratings from many people who own it. Actually, there are not many other units out there that have consistently high ratings like the EdgeStar.
