The Duct Shop

What The Duct Shop does

The Duct Shop is a family-owned HVAC ductwork manufacturer and direct-to-consumer e-commerce retailer founded in 1982 and headquartered in Buena Park, California. It operates one of the largest fully automated open ductwork fabrication shops in the United States, spanning approximately 250,000 square feet across four manufacturing facilities equipped with four Lockformer coil lines, six 22-foot plasma cutters, and four Spiral machines capable of producing over 200,000 pounds of ductwork and fittings per day. The company maintains over 2,000,000 pounds of galvanized steel inventory on the floor for immediate manufacturing, and its catalog exceeds 2,000 SKUs across 31+ product categories. Core products include adjustable elbows (45- and 90-degree), galvanized snap-lock sheet metal duct (manufactured in 3-foot lengths with 26/24/22 gauge steel), flexible duct (R6.0 and R8.0 insulation values), reducers, wyes, saddle taps, start collars (including Super Seal variants with self-adhesive gaskets), ceiling boxes, access doors, diffusers, return air cans, and supporting accessories such as duct sealant, tape, fiberglass insulation, hanger straps, and Tin Knocker fabrication machinery. A custom fabrication service builds non-stock items or new products from customer sketches at a 25-30% premium over stock pricing, with same-day build and next-day shipping.

The business serves primarily HVAC contractors, duct fitters, and installers working on residential and commercial job sites across the 48 contiguous United States, with secondary exposure to homeowners on DIY projects and large commercial construction accounts. It operates a direct-to-consumer e-commerce model via theductshop.com, bypassing traditional HVAC wholesale distribution; orders ship via UPS Ground for standard items and standard freight for oversized goods, with free shipping available on orders over $400 (code SHIP400). Revenue is generated through one-time product sales at unit prices typically ranging from $7.88 for small fittings to $200+ for larger components, plus the custom fabrication premium. Marketing relies on SEO-driven organic search, YouTube how-to tutorials, and educational articles targeting HVAC-specific queries. The company is privately held with no disclosed parent, no institutional funding rounds, and operates under a stated 'Managing By Values' philosophy emphasizing integrity, caring, and stewardship.
