There are various things that can cause problems with the hoses. The best way to address any issue is by first knowing how a portable air conditioner works and what common problems to look for. A portable air conditioner is an air conditioning unit that doesn't need to be placed in a window and can be moved from room to room. This self-contained unit cools the air just like a traditional air conditioner. They require two hoses to function properly: a drain hose and a vent hose.

As air is cooled by the portable air conditioner unit, moisture is being removed from the air. The condensation that is collected is drained from the unit using a drain hose. Based on the model of the portable air conditioning unit, the hose may empty this water into a bucket, or is pumped out of a window or opening designed for this purpose. ac unit for conversion vanIn some units, the hot air exhaust is used to evaporate the water that is collected.wall ac/heat unit If there is a problem with the drain hose you may notice that the water is collecting in the unit and not draining properly. portable ac unit best buySigns of this may be flooding around the unit, water leakage around the hose area, or the unit failing to operate. To check for problems, locate the drain hose and inspect for kinks or bends in the hose.

Also check the drain hose for holes and ensure that the hose is attached to the unit securely. If you find that the hose is damaged a replacement hose can be ordered from the manufacturer and installed fairly easy at a reasonable cost. If the hose is pump operated, inspect the pump for problems and repair as needed consulting the owner's manual. The vent hose, or exhaust hose, is used to pull air from the room, cool it, and return the cooled air back into the room. Some portable air conditioner units are equipped with two air hoses: one to pull the air into the unit and one to removed the hot air from the room. Air conditioner units with two vent hoses are more efficient and cool faster than units with one hose, but the cost may be higher due to the increased efficiency. If there are problems with the exhaust hose you may notice the unit not cooling the space or overheating of the unit. Signs of this may be an increase of the sound coming from the motor or the unit failing to operate.

To check for problems with the exhaust hose examine the hose for physical damage or air leaks coming from the hose. Also, if the motor is louder check the hose for obstructions and make sure that it is securely attached. Vent hose can also be ordered from the manufacturer and should be easy to replace.When a project requires an AC hose to be frequently moved between locations, it presents a unique set of demands that requires a portable hose. Portable AC hose products need to durable, flexible and compressible. They also need to be able to withstand the rigors of the outdoors. For work that requires high levels of movement, it is also important to have a retractable hose for convenient transportation. offers a large selection of portable hose that meet the demands of high movement work. A key feature of a portable AC hose is flexibility. Without flexibility it would be extremely difficult to move a hose between locations and air conditioning units. Our portable hose products feature excellent flexibility so that you can move the product to the perfect location to connect with an air conditioning unit.

The flexible material used to make these hoses transportable also provides them with great compressibility allowing you to retract the portable duct and easily carry it from one location to the next. For added convenience, our Tornado-Flex line of retractable hoses features an optional sack that the hose can be compressed and placed into for convenient travel and storage. The portability of these products does not affect the durability of the hoses; these ducts are designed to be resistant to outside abrasions.
