Has anyone who lives in a humid climate tried Kanberra Gel, or a related tea-oil based (or other effective) product, to fight moldy smells in a house? For example, by putting some of it in or near HVAC airhandlers or in ductwork?
Background - the former owner of my Florida house didn't believe in AC, and never or rarely ran (or repaired) her ancient HVAC system. While I swapped that out for a new system and some supplementary ductwork first thing (2 years ago), and have since had the all the ducts cleaned by a reputable company, I still notice a mildly moldy smell when coming in from having been out all day, especially in summer.
Not a huge issue, but if this Kanberra stuff can keep mold out of a boat, why not any enclosed space? Thoughts?
