Why South Dakota's Climate Makes Ductwork Quality Critical
South Dakota has a humid continental climate with about 170 days at or below freezing each year, average winter lows around 8°F, and typical snowfall of 40 inches. Ducts running through unconditioned spaces — attics, basements, crawl spaces — lose significant heat in those conditions if they're undersized, poorly insulated, or leaking at joints. In a long heating season, that heat loss adds up fast on your energy bill. Proper duct insulation and sealing are especially important in South Dakota's climate.How Much Does Ductwork Replacement Cost in Madison?
