Vent into an unused room.
no
YES you can! you can even use a dryer vent to the outside.
Portable air conditioners come with a vent hose that can be placed in a nearby window or vented through a hole in the wall like your clothes dryer.
This answer depends on if the air conditioner is portable or permanent. With a portable air conditioner you need a hose (if equipped, this comes with the free standing air conditioners) to vent out the hot air. But with the air conditioner that sits in the window you need a screw driver, screws and plastic curtains that go around the air conditioner to block off the rest of the window. On a permanent air conditioner that is built in the house it is best to have a professional install it because they are licensed to do so and will be equipped with all the tools needed.
No. Air conditioners should not be vented into a closed garage (even if there is an open window). Heat buildup poses increased risk for fires.
According to portable air conditioning suppliers, Mobile Air, all air conditioners have to be vented. But, there are different ways to "vent" the heat. The first way to vent is using water-cooled air conditioners. This type of unit uses water to cool the heat generated and requires a water source and drain. Mobile Air's website, , states that water cooled AC is required if the ambient temperature exceeds 115 degrees F. The second way to vent the heat produced is by using air. Air venting is done by using duct work to vent the hot air outside or by placing the unit outside to vent right into the air. This type is a bit more portable than water cooled.
Is it possible? Yes. Being worthwhile is a different matter, especially since a portable AC unit will not have the tonnage that a permanent AC unit would, and thus will take much longer to cool a building.
excessive humidity.
The air conditioner is low on refrigerant.
is it possible that the vent hose are disconected?
