Mid-Efficiency or High-Efficiency Furnace combustion motors:
•
Have your heating contractor determine if a smaller combustion exhaust fan can be installed. The combustionexhaust fan draws air from the home into the combustion chamber and vents it up the chimney. The majority of
these fans draw more air through the furnace than is required for it to completely burn the fuel, thereby reducing
the efficiency of the furnace, and sending excess conditioned air from the house up the chimney. Reducing the
size of this fan motor will reduce the electrical consumption of the furnace. Visit HVAC PARTS. CA for furnace and air conditioning parts.
