I am a new home owner (not new home), and I have a Heil Furnace model #NTC6075FBA1. Can you please help this newbie and not-so-handy female find where the air filter is on the furnace? I do not have a manual for my furnace and don't know where to locate the filter or what size replacement to buy. Thanks!
look inside the blower compartment pictures of the setup might help us to help you as well. Sometimes the filters are located in the equipment or the duct work or the return air grilles. hard to say where it is over the internet as each home and setup is different.
where do you live ..if in the south sometimes they the filters are in the hall ways behind intake register..maybe one on 1st floor an one on 2nd floor???????? sometime on bottom of furnace...or on side filter rack....happy hunting..ben
