Have bought a portable air conditioner for the bedroom as it gets really hot, curious if others worry about the noise from the hose venting out the window into the street? Not the noise of the machine that's in the room. I worry the neighbours might not be happy with it. A bit noisier than I expected and you can hear it outside on our drive. Anybody had any issues? Do others sleep with it on or just use it to cool the room before bed?
