What Aspen Manufacturing does
Aspen Manufacturing LLC, founded in 1975 and headquartered at 373 Atascocita Road, Humble, Texas, designs and manufactures evaporator coils and air handlers for the residential, multi-family, light commercial, and manufactured housing HVAC/R markets. Its product portfolio spans residential coils, multi-family coils, light commercial coils, and dedicated manufactured housing air handlers (including the AED/AEU upflow/downflow series and 14.5/17.5-inch space-constrained units), sold under the Aspen, Aspen Pro, and AirMark brands. Technical differentiation rests on AHRI 210/240 cross-certification with all major HVAC brands, 100% factory pressure and run testing, an award-winning lean manufacturing system, U.S. Patent No. 8,869,548 B2 for a dedicated horizontal plenum coil, and Dual A2L Refrigerant System Technology (launched August 2025) covering R-32 and R-454B under UL 60335-2-40 with universal RDS sensor kits. The company operates a pure B2B distribution model — selling exclusively to HVAC distributors and supporting them with a national network of local sales agents, factory technical support, and warranty services — and generates revenue through hardware sales of equipment and replacement parts on quote-based Net-30 terms with MOQs of 4–10 units. In March 2025, CSW Industrials agreed to acquire Aspen for $313.5 million in cash, with Aspen reporting $122.4 million in revenue in the prior year; the deal closed in mid-2025 and Aspen was integrated into the RectorSeal family of companies in May 2025.
