I have a 1500SF ranch home in Michigan that sits on a slab and the duct work consists of ceramic drainage tiles embedded in the concrete. Over the years as the slab has settled the tiles have cracked and water/sand have entered the system.
Im concerened about mold and inefficiency as the the air blowing at the far end of the home comes out of the vents is fairly cold (winter).
I want to change the system so that the conditioined air is delivered around the home through standard ductwork through the ceiling. I understand the best place for ductwork is in the conditioned space but due to low ceiling heights and asthetics soffits may be visually detracting.
The questions is with any product available today would there be an installation in the attic that would give us the same performance as that installed in a conditioned space? and if not what would be the best practice when attic installatioin is your only option.
Thanks for your time
