3 Great Reasons to Buy a Portable Air Conditioner

1. Oprah said so.

2. It looks like the robot from "Lost In Space".

3. Brad and Angelina are adopting one.

For those of you who make your decisions based on real information, here are

some cool portable air conditioner facts.

A goldmine of enlightening information can be uncovered by visiting forums. For

instance, when I wanted to tap into the experiences of actual portable air

conditioner owners, all I had to do was Google "portable air conditioner forums"

and Voila!, I had instant access to pages of relevant information from 3 different

forums.

I encourage you to try this technique. Just substitute any generic product or

service description for "portable air conditioners" plus the word "forums".

What I uncovered was concerns over energy consumption, how energy

consumption impacts circuit load, noise level, venting, the disposal of water from

the dehumidifying process, and of course, price.

Portable Air Conditioner Energy Consumption -

In the United States, the average air conditioner runs 750 hours each year. Since

air conditioners use a lot of electricity, their efficiency has become a public issue.

The EER, or Energy Efficiency Rating, is the ratio of the Btu's per hour to the

number of watts the unit draws.



EER ratings of 7 or 8 are at the low end of energy efficiency. Many units have

ratings around 12 which are good. The highest rated portable air conditioner I

could find was the Amcor AL10000E . It has an awesome EER of 16.6.

Portable Air Conditioner Circuit Load -

Before you start your search for a portable air conditioner, check your breaker

box for the number of amps available to the room you want cooled. If you buy a

unit that draws 14.5 amps on a 15 amp circuit, you'll have the additional but

unintended cooling effect of sitting in the dark while enjoying your new portable

air conditioner.

How Noisy Is A Portable Air Conditioner?

Most portable air conditioners that deliver 14,000 Btu's or less have a noise level

around 50 decibels. This is comparable to the loudness of most refrigerators. At

60 decibels, a 16,000 Btu unit is slightly noisier. Think of what it's like to watch TV

in the kitchen while the fridge is running.

Portable Air Conditioner Venting -

There is some controversy as to whether a dual hose unit is superior to the single

hose configuration. On one hand, a single hose unit will exhaust from the room

some portion of the cool air it just produced.

On the other hand, a dual hose unit eliminates this problem, but the warmer

unconditioned air used to cool their compressors results in slightly less efficiency.

They also use two internal fans which result in slightly higher energy usage.



Another hot topic at the forums that people are venting about is having to wrap

insulation around the hose of their single hose unit. This is done to prevent the

hot exhaust hose from adding heat back into the room. Personally, I can't think of

anything better than duct tape wrapped around insulation to brighten up a room.

Water Water Everywhere -

Portable air conditioners offer three methods for disposing of the water extracted

by the dehumidifier component.

The most convenient is auto evaporation which eliminates the need for drains or

reservoirs. The reliability of this method varies from unit to unit.

The second method is direct drain using a hose attached to the unit. This can be

problematic unless the unit is located near a floor drain. Not much chance of that,

so you'll have to use a bucket.

And finally, you get to empty the pan yourself. Just make sure the pan is large

enough so the air conditioner doesn't shut off in the middle of the night when the

pan fills up.

Price -

I think price is a secondary consideration to efficiency. As usual, a higher priced

unit that operates more efficiently will always end up costing less in the long run

than a cheaper, less efficient model.

Portable air conditioners are much less efficient than comparable window units

and cost roughly twice as much. What you're paying for is the flexibility to roll it

from one room to another or into a closet for easy storage.

Another Option to Consider -

For the price of a portable air conditioner you might be able to buy a window air

conditioner AND a new window to put it in.
