To insulate the hose on your portable air conditioner, you need to insulate the hose itself, seal any cracks or holes, and seal the connection with the window.
The exhaust hose on your portable air conditioner may seem like an inconvenience, but it is an essential part of removing the hot air in your room.
Fortunately, there are many options you can consider with which to insulate this hose properly to ensure that it does not accidentally radiate heat back into the room that you are trying to cool.
What does the hose on a portable air conditioner actually do?
The main characteristic that draws consumers to purchasing a portable air conditioner is how flexible and convenient these units are.
However, because a portable air conditioner is just a single unit, the excess water and heat that is removed from the air during the air conditioning process needs to go somewhere.
This is where the portable air conditioner hoses come in. Whether you have a dual exhaust hose, or a single exhaust hose portable air conditioner, these hoses are used as a means for the air conditioner to even the air pressure in the room and to get rid of the heat and moisture mentioned above. In addition to that, they also form an integral part of the air cooling process.
How do you insulate a portable air conditioner hose?
The problem, however, is that since one of the exhaust hoses of your portable air conditioner will always be used to expel the hot air that is extracted during the air conditioning process outside of your home, the hose will also get hot.
This means that this hose can act as a heating body in the room that you are trying to cool down.
If there are any air leaks or cracks within your air hose, it will exacerbate this problem, because the hot air will be able to seep back into your room, and your air conditioner will have to keep working to cool this hot air.
Fortunately, there are many ways that you can go about insulating your portable air conditioner hose, which includes trying to prevent the hose from heating up the room and preventing any hot air from seeping back into the room from potential cracks in the hose, or even in the connections between the hose and your windows or doors.
This ensures that your portable air conditioner works as effectively and as energy-efficiently as possible.
How to insulate the portable air conditioner hose
The radiant heat that can come from your portable air conditioner hose can actually end up heating the room while the air conditioner is trying to cool it down.
Fortunately, there are many materials that you can wrap around your air conditioner hose to try and minimise the amount of latent heat that can be transferred into the room.
The easiest and most popular way to do this is to use an insulated portable air conditioner hose cover, like this generic 59 inch one, which is specifically designed for this purpose.
This cover can simply be pulled over the hose and secured with zip ties at each end. However, you can also use other materials, like batting, towels, aluminium tape, and any other material that is an effective insulator.

How to fix any leaks in your portable air conditioner hose
Portable air conditioner hoses are generally made of a particularly lightweight plastic. This makes it easy to handle, but it also means that the unit can get damaged quite easily. If you notice any hot air leaking from your air conditioner exhaust hose, you can just replace the entire hose with a universal vent hose, like this Jin&Bao one.

If you do not want to replace the entire hose, but you still want to try and stop any hot air from leaking back into your room, you can use aluminium foil or speciality HVAC insulation tape that can withstand the high temperatures, to seal any holes or cracks that may be along the exhaust hose.
How to insulate the window connection of your portable air conditioner hose
Although most window kits for the installation of the portable air conditioner hose out of a window or a door are fairly well-insulated, the connection may wear out over time and this could cause hot air to leak into your room from the outside your house, which will have the same effect as if hot air was leaking out of the hose itself into your space.

In this case, it is best to seal the connection between your portable air conditioner hose and the window kit with the same speciality HVAC insulating tape that you used on the hose itself.
