Changed out the filters in my mothers oil Furnace.
Its about 7 years old and has been problem free
I use lower # Merv rated filters.
The question.
This furnace has two filters- one lies horizontal and another directly over top of it is slanted vertically.
Is there any air restriction from them using a double filter system? ( 16 x20 filters)
The double unit is new to me. This is a single system and a large 3 story house.
