I have another host right across the street from me with a Class A. He obviously has a heat pump, actually two, and I can tell when they are running from across the street. I don't hear them when I'm inside, but outside it is very obvious.
Of course in the summer when everyone is running 1 or 2 a/c's including me I don't even notice the bit of noise when outside.
