On Heil furnaces, look for the model number on the blower compartment door, inside the front access panel, or near the gas valve. Turn off power to the furnace before removing an access panel, then check the data plate for a combination of letters and numbers labeled "Model" or "M/N." Do not use the serial number, which identifies the individual unit. Enter the model number in the search bar to filter the complete furnace parts catalog to parts that fit your Heil model, including filters and other associated parts. That means fewer wrong orders and a faster repair.
