Your ducts won t be exposed to the elements.
Ac ducting without attic.
You can get the air handler and ducts into conditioned space in several ways without needing a basement or crawl space.
Iii special trusses that create space below the unconditioned attic.
Your attic is the most susceptible room in the house for this.
The remaining 2 tons of capacity is at least 1 5x oversized for the actual 1 load.
I lowered soffits around room perimeters.
If ductwork is covered with insulation without an additional vapor barrier there is not enough air flow inside to dry sweating ductwork.
Iv conditioned attic and more.
In more cases than not a 3 ton ac with the ducts in the attic has a ton or so of load that s just from the location of the ducts in the attic and the associated duct gains leakage etc.
Fibers may also work their way into closed system air handlers or ducts landing along duct work or circulating into the air in the rest of the house.
The air ducts for a central hvac systems are typically located above a home in the attic or upper crawl space or underneath a home in the space between the foundation and the floor so you don t see them unless you have cause to replace them.
Ii lowered ceilings in hallways.
