Here are some warnings about portable air conditioners to help you to be aware of their low energy efficiency rating when purchasing a new air conditioner. If you already have a portable air conditioner or if a portable air conditioners your only option to get some cooling, these fair warnings may help you understand your air conditioner and make better use of it. We will look in details why portable air conditioners are taking more room, wasting more power, producing more noise, and costing more money.If you are in a hurry, just looked the colored text, bookmark this page, and come back later when you have time.

Warning about "Portable"

An major claim of portable air conditioners is that they do not need installation and they are portable. On the internet or in the showrooms, we see portable air conditioners neatly displayed without a hose most of the time. In reality all air conditioners need to pass heat to the outside. Central air conditioners and window air conditioners use Freon to carry the heat to the outdoor coils. Fans are used to drive air to cool the outdoor coils.

A portable A/C brings the outdoor coil inside the room but still need to cool the coil. The coil passes the heat to air then the hot air has to be sent out the house. These pictures show portable A/C in actual use. They are less prettier than the units themselves – everyone has at least one bulky hose connected to the outside. Tip: The longer the total hosing the more power will be wasted to drive air through the hose.

Portable air conditioners need venting kits installed almost the same way as window air conditioners. It is true that the venting kit is much smaller than a window unit. However, you may run into the same installation problems as installing window air conditioners. Do you like the installations in the pictures? Think what the installation will look like in your house when deciding the purchase.

Once installed like the above, “Portable” is questionable. To move the portable A/C to different rooms, we need the venting kit installed in every room or re-install the venting kit for every move. Small wheels may not move well on carpets. Will the move be practical for you? Will the move be easier than with a window air conditioner? Tip: A window air conditioner is more efficient and weigh less as you see below.

Warning on Lower Energy Efficiency

The cooling capacity of an A/C is defined by its BTU/h rating. The BTU/h number indicates the amount of heat the air conditioner can remove from a room each hour. A hot climate will need more heat to be removed from a room to feel cool. A cooler room will also need more heat to be removed for the deeper cooling.
