    U had a lady with a one time noise bang sound in her ductwork, it comes from week duct caused week brake bending at the furnace. Need to find which one and a simple fix is to screw an "s" fleet across the duct to reinforce the duct.

    Heard you say 1 mushroom vent per 10 ft. xx 10 ft. =100 sq. ft., seems excessive. This would mean for 1200 sq. ft. you would need 12 vents. Did I misunderstand?

    I've heard that putting water softener pellets in the gutters at the beginning of the snow season helps avoid ice dams. Does this really work?
