The Air Conditioner No Exhaust Myth

Why Is the Air Conditioner Not Cooling
We have people writing in quite frequently asking about air conditioner no exhaust units. The fact is, all air conditioners need to have some type of venting in order to work Air Conditioner No Exhaustproperly.

I will explain the reasons why:

Portable ACs are the kind you can move from one room to another. There is no permanent installation required. They do, however, requite an outlet for venting. Walls and windows are the most commonly used venting outlets.

In some instances a drop ceiling can be used. Venting hoses are generally made out of temperature resistant plastic with some reinforced metal. After positioning your portable AC, you exhaust hose should be directed outside of the room in order to expel the hot air away.

Some AC manufacturers claim that they’re selling portable ACs that require no venting. This is simply a myth. All portable ACs have to be vented in order to remove hot air from whatever room they’re cooling. An important note is that hot air doesn’t need to be vented through a window.

An additional option for these portable units is to use them in a place where hot temperatures are not the issue, like some type of storage room.

The reason portable AC units have to be vented is because that’s the only way they will function properly. If hot air doesn’t get vented to another area, then the portable AC is not going to work efficiently. The process of venting is not expensive.

Most portable ACs come equipped with an installation kit that can be used for a sliding door or a window.

There are some simple steps you can take when you vent your portable AC. The first thing is to locate a place for venting, whether it’s a wall, drop ceiling, or window. Next, you want to slide the exhaust connector directly over the discharge opening in back of the AC unit. Now, connect your exhaust hose to your exhaust connector.

The next step is to connect the venting window kit adapter up with your window kit. Lastly, you need to set your window venting kit carefully into the window, and then shut your window.

The way a widow kit works is by being cut to fit to your window or sliding door. Your window will close against the foam seal, and will keep the outside air from coming inside. The exhaust hose fits through a small cut you make in the foam. Single installations only take around 5 minutes to complete, and you will be able to move your unit from one window to another easily.

The best length of exhaust hose will be from 5 to 7 feet long. It needs to be at least 5 inches in diameter. Your hose length should never be extended. Should you extend your hose, and find that it constricts the flow of air or back-pressure exists, then you until is not going to work properly and may even be damaged.

If you have a circumstance where you absolutely must extend your hose, then be sure that its diameter is increased as the length is increased. You should realize that you are going to lose some efficiency with this type of setup. Always read your warranty manual prior to making any kind of alterations to your hose. Some manufacturers frown on that.

One last thing to take notice of is that when you vent out of a dryer vent, most all manufacturers recommend against that. This is especially true if the dryer vent diameter is smaller than your portable AC hose. When a dryer vent contains external vents, it should never be used as an option for venting your unit. The compressor on the portable AC unit doesn’t have the strength to push those flaps open.
