Tips for How to Choose Portable AC Units

When determining what to look for in a portable air conditioner, there are a few key considerations you should take into account:
- Measure Your Space: When looking at your space, you'll also want to keep other factors in mind, such as distance from a power outlet. A portable air conditioner won't do you much good if it's located too far away from a plug. In many cases, portable air conditioners will vent to the outside through a window. If you choose a unit that operates this way, you will of course need to make sure that you have a usable space near your window to place your portable ac unit.
- Ensure BTU Rating Is Sufficient: The power of a portable air conditioner is measured in BTUs, which stands for British Thermal Units. This is a measurement of how much heat an air conditioner can remove from a space in one hour. As would be expected, the larger the space you are trying to cool, the more powerful your portable ac should be. More powerful air conditioners will have higher BTU ratings. To get a sense of what BTU rating you should look for, start by measuring the square footage that you are trying to cool. Generally speaking, if you have 8-ft. ceilings, you can expect that a 150 sq. ft. space will require a unit with 7,500 BTUs. For 300 sq. ft., you would need around 10,000 BTUs, and for 500 sq. ft., you should look for approximately 14,000 BTUs. Keep in mind that if you have high ceilings or many windows or doors in the space, you will have better outcomes with units offering higher BTU ratings.
- Additional Heating For Winter: Did you know that there are portable air conditioners out there that don't simply cool the air? There are some companies that make units capable of serving as both heaters and air conditioners. With this kind of flexibility, you can enjoy comfortable living spaces all year round without the expense of installing centralized units or the hassle of buying separate heaters and air conditioners. Friedrich is one example of a company that produces smart portable air conditioners that can also serve as heaters. As specialists in air conditioning, they've got these sorts of offerings down to a science. LG also makes portable air conditioners/heaters and brings with it decades of experience in the home appliances arena.
