Also, you want to place the supply and return grille in symmetry so that they look good. The bigger the crosssection of ducts, the bigger CFM; that's pretty obvious. Question: How often should I replace my air filters? Basically, you use the space above the ceiling as a plenum for return air. Check the vents and registers in each room to ensure the spaces behind them are sealed properly and that there are no leaks at the grille. For each room, there will be a particular velocity that the air should be delivered through the ducts in order to heat or cool that room. If you know how many CFM per egg you need, you can quite easily calculate that, hope this helps a bit. In addition, you'll need the cubic feet per minute (CFM) for the system. Hi Randy, according to EPA citing ASHRAE, the average air change per hour for homes and houses is 0.35 ACH. root the value. There is no loose part or rattling noise.
