I just had a new HVAC system installed. It is a zoned system (one zone is upstairs, one zone is downstairs). The System is in the Basement which is unconditioned. The compressor is two-stage, 70/100 (Trane XL18i). There is currently a bypass with a barometric damper which goes from the supply to the return ductwork. Would it be better to have this bypass just dump into the basement so that the air going into the return isn't too hot or too cold?
