Additional Return Air Runs
Solve many system airflow problems
Insufficient return air is a very common problem for furnaces and central air conditioners. It is also a problem that can be easily cured. Ductwork, although it may look like artwork is really all based on air flow and math. If air ducts are not properly sized based on the amount of air needed to pass through them the system will not function properly or at its designed efficiency.
Every furnace or central air conditioner has a blower that pulls the air from within the home (The return side) through the heating and or cooling system and then pushes the air back throughout the home (The supply side).
The blower motors that heating and cooling systems use come in two basic types and a variety of sizes. The two types of blower motors are direct drive and variable speed.
