So my parents have had an air-to-water heat pump standing in front of the house for many years... directly in front of the kitchen window, and neither in the kitchen nor outside in the seating area in front of the house has it bothered me with noise so far. The humming is even so muted that I really have to concentrate to be able to say at all whether it is humming or not.
