Furnace Air Flow Direction Diagram

Pushing air cool or heated in and pulling spent air back in for another cycle.

Furnace air flow direction diagram.

The first step to an effectively filtered heating ventilation and air conditioning system is the correct insertion of a furnace filter. Upflow downflow and horizontal. Now you never need worry about the furnace filter direction again. This tends to confuse everyone more than anything else.

A furnace filter has one side that allows it to breath fresh air through while the other side traps dust and particles from the air. On your new air filter find the arrow that indicates the proper air flow direction. The right way to insert a furnace air filter. Remove the old air filter from your furnace.

Furnace and air conditioner filters are important devices for helping to remove dust and pollutants from the air in your home and are often designed to have air flow through them in a particular direction. That arrow must always face toward the furnace and away from the return duct that carries the air in need of heating or cooling. The most common terms used to describe the air flow configuration are.

The term air flow configuration describes the physical orientation of a furnace relative to the direction in which heated air leaves the furnace and enters the ductwork. Which way does furnace air flow.
