Old Lennox Furnace with hammock style filter system
I am a first time homeowner, and I grew up living in apartments. I have never had to deal with a furnace. How does the filter go into the basket in this type of furnace? I have a roll of fiberglass, one side blue and one white. I have it with the blue side facing outwards. Is this right? I appreciate your help and apologize if this topic is already out there somewhere. I couldn't find it.
