I recently had a new Trane HVAC heat pump/air handler system installed for my home upstairs zone. The variable speed air handler model is
4TEE3F31A1000A. The wind rush noise coming thru the supply vents is order of magnitude greater than the old system. The first night the system came on, we thought a terrific storm had whipped up outside. Itr is so loud as to make sleep difficult.Is there any way to ramp down the max fan speed? My installer says no. Another Trane outfit I spoke with says yes -- it can be contolled by internal dip switch settings. Before I call my installer, I'd like to know for sure what is and is not possible in the way of changing fan speed settings. Can anyone provide some advice? Thanks.
