Heat pump noise?

vCWJKZSiuP | Posted in Mechanicals on

Recently a client asked me to help him solve a problem with noise in his house which he attributes to a deep-well heat pump his neighbor has.He says the noise is a muted pulsing sound that seems to occur at night when the pump is running.There is no noticeable sound outside the house,as it would be if traveling through the air,and I wonder if it is possible that the sound is being transmitted through the ground.There is a good chance there is solid granite that lies under both houses,which are about 150 feet apart.

    Just to clarify: I think you are asking about submersible-pump noise, not heat-pump noise, but I may be misunderstanding you question.

    If I understand correctly, the neighbor has a ground-source heat pump using a drilled well as an open loop. If that's correct, the neighbor's heat pump is in the neighbor's basement. The equipment at the bottom of the drilled well is an ordinary submersible pump.

    I have never heard a case of noise transmission attributable to a submersible pump in a drilled well.

    Do these houses share a water line (town water or community water system)?
