Our Best Cooling Models Shown

What size portable room air conditioner do I need.
The cooling capacity of an air conditioner is measured in British Thermal Units (BTU), and the capacity you require depends mostly on the size of the room you need to cool. If you buy an air conditioner that is to small for the room it will not cool adequately. If you buy one that is too large, the air conditioner will cool the room before it dehumidifies and this can leave you feeling clammy. For larger areas, sometimes two smaller units are more efficient than 1 large unit.

Make any adjustments for the following circumstances: (energystar.org)

Heavily shaded rooms, Reduce capacity by 10%.

Very sunny rooms, Increase capacity by 10%.

If more than 2 people regularly occupy the room, add 600 BTUs for each additional person.

If the unit is used in a kitchen, increase capacity by 4,000 BTUs.

Consider where you install the unit. If you are mounting an air conditioner near the corner of a room, look for a unit that can send the airflow in the right direction.

Venting / Exhausting

Do portable air conditioners require venting?

  Yes, all portable air conditioners require some type of ventilation. It is important that you vent the hot air outside of the room you are trying to cool.

  Our entire units comes with hoses to vent the exhaust and window filler kits to allow you to properly vent out of most windows. However, you do not need to vent the hot air out a window. The window venting kits also fit most sliding glass doors ( if you make modifications , or you may make a custom modification and vent the exhaust through a wall do not install exhaust hose into a drop ceiling or anything that does not vent outside
