Unlike traditional window air conditioner units, a portable air conditioner is not designed to sit in a window. Instead, a portable unit sits on the floor of the space you are attempting to cool, while an exhaust hose carries the hot air out of the room through a window. Since the unit does not function in the same manner as traditional window units, any fair portable air conditioner reviews must take into account the unique features and challenges of the portable units.
Size of the Portable Unit
Though you might assume that a portable unit is going to automatically be small and light weight, that is not always true. At 48.5 pounds, the LG LP0711WNR earns high marks in portable air conditioner reviews for its smaller size. However, other units can weigh over 80 pounds.
How Many BTUs Do You Need?
You may be wanting a smaller unit, but that smaller unit might not cool the space effectively. As is the case with all air conditioners, portable units’ cooling power is measured in British Thermal Units (BTUs). Units with a higher BTU can cool a larger space. If you only have 150 sq. ft. to cover, then a unit with 7,500 BTUs is acceptable. But if you need to cover 500 sq. ft., then you will need a unit with 14,000 BTUs.

Many people look at portable air conditioner reviews to see how energy efficient a product is, because they are worried about the environment or their monthly electricity bills. If you are one of those people, then you should pay attention to the Energy Efficiency Ratio, because it tells you how many BTUs are used for each watt of power. Portable units with a higher Energy Efficiency Ratio are more energy efficient than those with low scores. Toyotomi products earn excellent portable air conditioner reviews because of their energy efficiency.
As the air is cooled, the moisture is removed, which means that portable air conditioners must deal with the water after it has been removed from the air. The cheaper and simpler models have buckets that collect the water, and these type of units require you to empty the bucket periodically. More advanced models will automatically evaporate the moisture, which will save you time and energy. If you are gone from your home for long periods, but still leave the unit running, you may need to purchase a more sophisticated model.
