More compact ducts will have challenges given that they will trigger the contemporary air to pool near the HVAC unit. Not more than enough in the fresh air can make it into the rooms you wish to heat or amazing. The HVAC device will have to work time beyond regulation just to deliver a moderate volume of heating or cooling.
