Lenny Steinberg asks,
I have a 3-story house with a basement. The home has 3 zones of HVAC. Lately I've noticed a musty smell in the stairways which do not have vents and are not air conditioned. The the hallways on the sleeping floors have the same musty smell. I assume this comes from moisture. How can I adjust my HVAC to get rid of the odor?
