A portable air conditioner hose can deteriorate or become damaged and need to be replaced. 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 kind of air conditioner is designed to cool a room in the same way as a regular air conditioner. There are two hoses on the portable air conditioner. They are the vent hose and the drain hose.

Step 1 - Check the Drain Hose

When the air is cooled by a portable air conditioner unit, air moisture is collected and has to be drained from the air conditioner via a drain hose. The hose sometimes empties into a bucket. Often it is pumped outside through a window or vent. Some units use the hot air exhaust to evaporate the condensation, eliminating the need for draining.

You may notice that water is collecting in the unit. The water should be draining out instead. If you see flooding, leaking, or dampness around the unit then it may be a problem with the hose. Inspect the hose to see if it is kinked or bent. Look for holes in the hose, even pinpoint holes that are difficult to see which can cause problems. Next examine the fitting. See if the fitting is tightened well, if any seals appear to be damaged or if there are any other problems. If it is a damaged hose then you will want to replace the hose. You can get a replacement from the manufacturer or prehaps from the dealer where you purchased the portable air conditioner. Once you have the hose simply refit it to the unit with the existing fittings. If there is a pump examine the pump to be sure it is working properly. Listen for any unusual noises. Look for water leaks or condensation around the pump.

Step 2- Check the Vent Hose

The exhaust hose vent pulls the air from the room and cools it. Once it is cooled down it sends it back into the air. Some units may have two different hoses. One hose is for removing heat from the area. The second hose is used to return the cold air. If there is a problem with a vent hose it could result in overheating of the unit. You may also notice a sound coming from the motor. Check the hose for kinking, or any damage including air leaks. Check to make sure the hose is firmly attached to the motor. If you determine that the hose needs to be replaced you can easily order a replacement hose from the dealer where you purchased the air conditioner or from the manufacturer if necessary and install it yourself. Simply remove the damaged hose and use the same fitting to put on the new hose.

If there are problems that you cannot diagnose then contact the dealer or call the technical help line for the manufacturer. You may be able to find a troubleshooting guide or ask questions on the manufacturer's website.
