Hi CoolJoe - Thanks for viewing GE! The air conditioning process is basically moving warm humid air outside so the hoses are designed primarily to move heat and humidity from a room. These units are sold with a 5' exhaust vent hose with a 5” inch diameter. Operating the unit without an exhaust vent will not allow heat and humidity to be removed from the room. The unit will not function properly without an exhaust vent. Additionally the unit must be vented outdoors, not into an attic or other indoor space. If you have any additional questions, do not hesitate to ask, we are also happy to help at GEAppliances.com! Sue
Sorry, there was a problem. Please try again later.hey! i tried to not vent it, but it throws heat out of the back, so it will not cool the space very effectively because of the heat. So, yes I’d say it’s necessary.
