What J. P. Lamborn does
J. P. Lamborn Co. (JPL) is a US-based, family-owned manufacturer of flexible HVAC air ductwork, founded in 1961 in Fresno, California, by John P. Lamborn Sr. The company produces flexible air ducts for residential and commercial air distribution systems, using spring steel wire helix cores encapsulated in polyester, aluminum foil, and antimicrobial-treated inner cores, with fiberglass insulation sourced from Owens Corning. Its product portfolio spans multiple series (AMF, FHP, MF, MH, MHP, PR) at R4.2, R6, and R8 insulation values, plus air connectors (MNI-25), thermal sleeves (MT-05), and a premium antimicrobial line (AMBlue II) treated with Agion silver. The entire product range carries UL-181 listing, UL GREENGUARD Gold certification, Class 1 Fire Hazard Classification (FHC 25/50), and BABAA compliance.
JPL operates four state-of-the-art manufacturing facilities in California, Colorado, Florida, and Tennessee, and distributes exclusively through HVAC wholesalers (HARDI member organizations) reaching 46 of 50 US states. The company is led by third-generation President Jason Lamborn (joined 1997), supported by an eight-person regional sales manager team covering the continental US and Alaska. The company does not sell direct, publish pricing, or maintain public revenue disclosures.
Revenue is generated through wholesale hardware sales of physical duct products to distributor partners, who in turn supply HVAC contractors and builders. The business model emphasizes specification-grade certifications, a 10-year limited warranty, and contractor-facing technical tools (online friction loss calculator, installation FAQs) to drive pull-through demand at the contractor level. No external institutional investors, public listing, or private equity backing are indicated.
