Portable Air Conditioner


If you have been wanting to cool yourself down this Summer and Fall, and are considering the advantages of a portable air conditioner, but are looking for ac buying advice and portable air conditioner reviews before you buy, then you have landed in the right spot. In this short article we will reveal a really odd fact that might shock you and might just save you hundreds of dollars that you could have wasted on buying a portable air conditioner, especially a small portable AC, or a cheap portable AC. So read attentively.

Portable air conditioners are popular

Portable air conditioners are becoming popular because of their relatively simple installation, no need to build ducts as with ducted air conditioning units, drill holes in the wall as in through-the wall air conditioning units, or take up significant portions of the window surface, such as needed with the window air conditioning units.

Portable AC units help students in their dormitory rooms, they help apartment dwellers who are limited in their ability to modify the infrastructure of their homes, and they help home owners with existing central AC systems in their homes. Indeed, even if you already have a central air conditioning functioning, you may still want to save additional money by selectively cooling air only in spaces that are occupied, such as living rooms during the day.

The odd fact – some portable air conditioning units come with a single hose!

You need to be aware that there will be a hose running from the unit toward the window to exhaust the hot air out through the window. And there lies the rub. The odd fact that few manufacturers of portable AC units will say loudly and openly, is that a single hose is simply not enough. You need the air intake hose and the air exhaust hose, both extending towards the window and circulating the outside air around. Why?

Why a single hose is not enough?

Imagine a single hose blasting the very hot air out the window. Well, yes, you will get some chilling effect on the other end of the portable AC unit. But ask yourself, since you are not running out of air in your room, where does the air which is replacing the hot air that is blasting out of the window coming from? Well, the answer is simple, it comes from the outside of the room. Be it through the cracks in the windows or doors, be it through the ducts, it comes from the outside of the room. And, considering that you are trying to cool your room, in all likelihood this air coming in is quite warm. So what is happening with a single hose portable AC is that the unit is constantly cooling down the new hot air coming from the outside. Very ineffective. Let’s contrast this with a dual hose portable AC unit.

Why a dual hose portable air conditioner is the best

With a dual hose portable air conditioner, the air from the outside of the house, figuratively speaking, makes a full circle. It starts as a relatively hot air from the outside, goes through the intake hose to the portable air conditioner, takes on some heat there, and is eventually exhausted through the second hose to the outside air. Big difference compared to a single hose system: The air in the room is still the same, it did not have to be sucked in from the outside. Therefore, by closing the circuit of the outside air using the dual hose, we have to a large degree been able to cool the same air inside the room all the time. Therefore, that same air can be cooled down faster and to a lower temperature as if we had to constantly chill the new incoming room air.

You could compare having a single hose portable air conditioner to using a car air conditioner with the car windows rolled down, and you would have a perfect analogy. Or you could compare a dual hose portable air conditioner with a car air conditioner with the windows rolled up.
