Ac Ducting Without Attic

Iv conditioned attic and more.

Ac ducting without attic.

If ductwork is covered with insulation without an additional vapor barrier there is not enough air flow inside to dry sweating ductwork. 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. I lowered soffits around room perimeters.

Another way your ducts lose energy reducing your hvac system s effectiveness and costing you extra money is when hot or cold energy from outside air literally forces its way through your ducts changing the temperature of your air. The reason ductwork is exposed is because it sweats in the summer when a c is on the surrounding air will dry the sweat. The remaining 2 tons of capacity is at least 1 5x oversized for the actual 1 load. Ii lowered ceilings in hallways.

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 ducts won t be exposed to the elements.
