We have a 12 yr. old Lennox oil furnace with a Ducane burner. Broke last night and new part cost a fortune and no longer made. Service tech happened to have one this morning, hates Ducane burners. Recommended Hallmark furnace and Rialo? burner, what he has in his house. Looking for feedback on these and other furnace/burner options. May have or want to replace soon.
