[quote=Anonymous][quote=Anonymous][quote=Anonymous]Forced air heating systems... "degrade indoor air quality because the buffer spaces where ducts are located are often moist and have large amounts of biological activity (crawlspaces), dust [b][size=giant]including cockroach[/size][/b] and other allergens (attics), and vehicle exhaust or solvent storage (garages). Thus an HVAC system may serve to increase contaminant loading in a space and may introduce contaminants " One study (of MANY) by University of Texas at Austin: http://www.caee.utexas.edu/prof/siegel/papers/conference/siegel_forcedair_hb_680.pdf[/quote] [b][color=red]EEEK![/color][/b] :shock: [/quote] The code calls for those ducts to be sealed and insulated and wrapped. Not an issue anymore. [img]http://www.energyvanguard.com/Portals/88935/images/duct-system-trunk-and-branch-hvac-design-endcap.jpg[/img][/quote]
