LENNOX oil furnace that's been there for 6 years and it supposed to stay there in the basement as I have not ordered to replace it. But the guys removed it to outside and it rains heavily now. Do you think the oil furnace will get damaged in some way while staying in the rain? The oil furnace filter probably is useless when wet. Well, it's not just oil furnace, but a furnace that's gonna be used to put a new ductwork and new heatpump on. The guys had to toss the furnace on a side to get all the water out of it. They brought it backinto the basement. Do you think I can still use that fuirnace or did TSC company screwed it up? Please help. Thanks a lot.
