    AS Heritage 14 heat pump/variable speed air handler

    My second floor runs on an american standard variable standard air handler connected to AS heritage 14 heat pump. Few months ago I had the heat pump moved and the tubes rerouted.

    I am not sure if this is related to relocation, but when the heat pump runs during the cooling stage, I can hear a squeeking/hissing sound around the valves. Almost sounds like freon moving. However, the sound radiates through the pipes and I can hear that noise through the house walls. Is that normal or shall I have a technician look at it.
