Low or high for HVAC return vent?
In Minneapolis Zone 6 my general contractor and his HVAC sub insist that the proper return vent location is high on the wall near the ceiling. This seems counterintuitive as heat rises wouldn’t I want the returns low to circulate. As the supply heat enter to room and rises the return vent would draw that warm air back down. The opposite would be true when running our AC but we only run the AC for about 1 month and the furnace runs from at least October through March.
