Portable Air Conditioner FAQ 

How is a portable air conditioner different from a window AC?

AC-12000E Image8A portable air conditioner is a small, mobile air conditioner which which doesn't require permanent installation in wall or window. All of our portable air conditioners are between 29 inches and 34 inches tall and weigh between 65 and 80 pounds. Portable air conditioning units also work great in apartment situations where a window air conditioning unit is not an option.

Are portable air coolers and portable air conditioners the same?

No, portable air conditioners and portable air coolers are not the same. Air coolers use water and evaporation to cool like a swamp cooler. Only the direct air stream is cooled by 10 to 15 degrees, not including ambient air. Portable air conditioners use a compressor and Freon to cool, keep humidity levels low, and are much more effective than air coolers.

Why and how are portable air conditioners vented?

Portable air conditioners extract hot air that must be vented. If the hot air is not vented outside, a portable AC will not effectively cool the room. Window venting kits are always included with our portable air conditioners at no extra cost. You can vent a portable air conditioner through a wall vent, an attic, a drop ceiling, or even around a door! Use Plexiglas for venting a portable AC system through casement windows (windows that crank out). Simply cut the Plexiglas to the size of the window, cut out a 5-inch hole to vent the hose, and place over the open window. Not only is the air conditioner vented by this method, but Plexiglas will allow the same amount of light to pass through the window as before.

How long is the exhaust hose?

Portable air conditioner exhaust hoses are generally between five to seven feet long and are made of high quality, 5-inch flex hoses.

A foam window kit is cut to fit most home windows, such as any slider or up and down  window, up to four feet (for windows larger than four feet, simply purchase extra foam from your local hardware store). The window is closed against the foam to seal the air from the outside, and the exhaust hose is then fit through a small cutout in the foam. Installation takes about five minutes, allowing portability from window to window.

Can the exhaust hose be extended?

All of our portable air conditioners come with a standard hose, five to seven feet in length. Longer hoses are readily available at the local hardware store, although it is a good idea to avoid hose lengths of over 12 feet or 90 degree bend. You can also vent through the dryer hose as long as the hose diameter is five inches or more and the outdoor venting flap is removed.

Do portable air conditioners collect water?

Most portable ACs produce condensate water as they cool the air, collecting the water in an internal water reservoir. On all of our models, this water reservoir has an auto shut-off feature, so that water is never spilled on the ground. With the unit off, the water is easily emptied into a drip pan. You can also gravity drain the portable AC by connecting a hose to the connection on the reservoir. Many newer mobile ACs feature self-evaporative technology that utilizes collected water to cool the compressor coils. These units, such as the AC-12000E Portable Air Conditioner by NewAir, create very little extra water, and rarely need to be emptied except in the must humid weather.

Will my new portable AC be energy efficient?

randomsharpunitThe Energy Efficiency Ratio (EER) is the standard measure of efficiency when comparing appliances and operation costs for products such as portable air conditioners. The higher the EER, the more energy efficient the air conditioner is, and any rating of ten or more is considered excellent. Furthermore, by cooling only one room, portable ACs can save you a considerable amount of money on your monthly electric bill. All of the portable air conditioning units we carry operate on normal household standards of 115 volts and 60 hertz. They generally run on about seven to ten amps and require a regular three-pronged grounded plug found in all homes.

Are portable air conditioners used to cool computer server rooms?

This is one of the most common uses for a portable air conditioner! Even in small computer rooms, a 12,000 BTU unit should be purchased due to the extra heat produced. Moreover, a portable AC will help keep the air comfortably dry and more suitable for computer application.
