A ventless portable air conditioner is a great choice for people who want cooler air in their bedroom, office, family room, or any other area in their home, without complicated setup or installation and at a reasonable price.
That’s why, we at Know the Flo, are excited to present our all-new buyer’s guide, review, and comparison of the best ductless portable air conditioners currently available.
What is a Ventless Air Conditioner?
A ventless, or ductless, the air conditioner is, strictly speaking, not an air conditioner at all! It is an evaporative cooler, or a swamp cooler, which operates in a fundamentally different way than an air conditioner.
A proper AC unit uses refrigerant and fins to extract heat from the air inside your home, ducts to move the hot air outside and fans to move the now cold inside air all around.
A ventless AC is, by comparison, almost absurdly basic. These units simply draw air across water or ice and then blow the cooled air throughout the room.
There are no tubes that need to be somehow run to the outside of your house, no window mounting, no special installation at all, in fact. They have no hoses or ducts, don’t have to be set in a special place, and don’t require you to drill a hole in the wall or strap a big box to your window sill.
How Does a Ventless Air Conditioner Work?
It really couldn’t be easier! You just put the portable ventless air conditioner just where you want it, fill it with ice, water, or both, plug it in, and turn it on.
Of course, these much simpler and much less expensive units are not nearly as powerful as a true air conditioning unit. They will not drop the air temperature nearly as much, nor will they cool as large of a space. They also require that you periodically refill the ice/water tray.
That said, they still offer some substantial benefits, not the least of which is the price.
