Yes sir, I love working in the local birdhouse. We pulled the a coil out last fall and had to take it to the car wash to clean all the disgusting filth out of it(coil was icing) Built new return with more filter area and I'll be da#### if the idiots didn't run it without filters for a while cause someone didn't go to the store and get new ones. Guess what ...... Yep, furnace was going off on high limit...got to go in the loud stinking crap hole again and pull the coil and car wash again. Just venting, thanks for listening......I feel better now!!! I still love it, although sometimes I wonder why.
