How can you vent a one or two vent hose from a portable room air conditioner thru a casement crank style window providing a water tight seal. Window is in a upstairs bedroom.
Are the two vent line for windows better than a single hose (one for exhaust and one for emitting fresh air and air balance)?
Any brands recommended.
If not practical would a portable room dehumidifier help some? Michigan, where summer temps hit 85-100. Have central air. Tried closing some 1st floor vents to help push air upstairs but not much help. Will also try a floor vent booster fan to see if it helps.
Casement window width is only 25" and using a small regular a/c would present an even harder sealing problem.
Thanks for advice in advance.
Have heard closing off 1st floor cold air returns might help????
Our first floor very comfortable. Attic well insulated with ridge vents.
