How long is a portable air conditioner hose?

Portable air conditioner exhaust hose lengths differ from one model to the next and can be extended, but they are usually the standard length.

Portable air conditioners are very convenient because they can be moved around and they are contained within a single unit.

However, portable air conditioners still need to get rid of the hot air that they extract from your room. Most portable air conditioner models come with a standard length exhaust hose, but you can extend this hose if you need to.

How portable air conditioners work

Portable air conditioners are popular because they provide all of the same cooling and dehumidifying functions that other types of air conditioners do, but this type of air conditioning unit is conveniently mobile, so you can move it around your space as you please.

This type of unit works the same way that other types of air conditioners do, by extracting warm air and moisture, running the air over cold coils, and then only blowing the cold air back into your space to lower the overall temperature of the space.

How long is a portable air conditioner hose?

Portable air conditioners do differ from other types of air conditioners in that other air conditioners have an internal unit and an external unit, but portable units usually only have a single indoor unit.

This means that the hot air and humidity that is extracted from the air in your space needs to be expelled somehow. The way that portable ACs get rid of this excess hot air and water, is through an exhaust hose.

This exhaust hose pumps out all of the hot air that the air conditioner removes from your room, which is why it is important to ensure that your unit can be vented outside.

If you do not, you will simply be pumping this hot air back into your room. Although there are other workarounds for spaces without windows, the most common place for this exhaust hose to go is through a window.

However, this can be tricky if you want to use your portable air conditioner in a larger room or in a variety of rooms in your home, as you will need to make sure that this exhaust hose can always reach through the window.

Every portable air conditioning model typically has its own specifications about how long the exhaust hose needs to be for the air conditioner to function optimally, but generally, portable air conditioning exhaust hoses are four to seven feet long.

You can also extend this hose yourself if you really have no other choice, but there are some risks involved in doing this, and the length should never exceed 12 feet.

Specific portable air conditioner hose lengths

Most of the exhaust hoses or vents that are included when you purchase a portable air conditioner can be extended or collapsed to make them longer or shorter.

The unit’s functionality is usually better when the hose is shorter, but it will still be safe to use your air conditioner when the hose is extended to its maximum length.

The BLACK+DECKER 8,000 BTU Portable Air Conditioner, which you can purchase for $339.99, can cool down rooms of up to 150 square feet, and has a 4.11 feet exhaust hose included when you purchase it.

On the other hand, the Whynter Elite 12,000 BTU Dual Hose Portable Air Conditioner is $414 and can cool rooms of up to 400 square feet. The exhaust hose included in this purchase is extendable up to 4.9 feet.

What to consider before you extend the exhaust hose for your portable air conditioner

If the average length of exhaust hoses or the hose that comes with your specific air conditioning unit does not quite seem long enough for the hose to reach the window from your unit, you can extend it.

However, it is important to note that this may negate your warranty on your portable air conditioner. If you are not worried about the warranty, keep in mind that your air conditioner functions best when its exhaust hose is as straight and short as it can possibly be.

How to extend the exhaust hose for your portable air conditioner

In cases where it is absolutely crucial that you extend your portable air conditioner’s exhaust hose, you can do this by purchasing a simple exhaust hose extender.

It is also important that you thoroughly seal the place where you joined the old hose to the extension with a coupler and foam tape to prevent hot air from escaping.
