The Effects of Dirty Return Vents on Furnace Efficiency

Numerous studies have shown that dust and dirt buildup can affect the performance of your furnace. The concept is simple. As dirt builds up around the vents, it blocks the passageway for warm or cool air. Since the furnace forces the air through the ductwork, the blocked vent creates additional pressure in the system. The furnace, however, must continue to do its job of circulating the conditioned air through the house. The difference is that it must now work twice as hard to perform the same task at the same level.
