Bringing an Attic Furnace / Air Handler into Conditioned Space
Want to bring furnace/air combo unit into conditioned space. It’s a 1950s, 1.5 story, located in zone 5 with furnace/air in third floor attic. The unit is suspended and close to roof rafters. The rafters are 2×6, and the roof is vented. It’d be challenging (and more expensive) to put unit and all ducts into conditioned space by insulating ceilings in entire roughly 40′ length with 5′ and 13′ rafters. If just bringing the unit into the conditioned space, what is code regarding insulation? Any recommendations would be appreciated.
