D&L

What D&L does

D&L, Incorporated is a privately held, full-service HVACR (heating, ventilation, air conditioning, and refrigeration) contractor founded in 1978 and headquartered in Blytheville, Arkansas. The firm designs, engineers, installs, and maintains commercial and industrial HVACR systems, supplemented by a dedicated sheet metal fabrication shop with CNC plasma cutting and roll-forming equipment that produces custom ductwork, commercial kitchen hoods, industrial platforms, and storage racks. Its service portfolio spans commercial HVACR (serving school systems, banks, and churches), industrial HVACR (serving factories and steel mills with ventilation, refrigeration, and overhead crane maintenance), new construction system design and installation, and customized preventive maintenance programs with dedicated technical crews and stocked critical parts.

The company's underlying technology centers on the JENEsys Building Operating System powered by the Niagara Framework, which integrates Bac Net, Lon, and NDIO networks to deliver building automation, energy management, remote diagnostics, and preventive maintenance for facilities ranging from small commercial buildings to large industrial plants. Engineering work is delivered in conjunction with affiliated firms that provide signed and stamped drawings.

D&L makes money primarily through professional services: project-based, quote-driven HVACR installation and maintenance contracts, plus one-time sheet metal fabrication and installation engagements. Pricing is not publicly disclosed, and engagements are structured as multi-year maintenance contracts and project-based commercial work. The go-to-market motion is direct field sales supported by a fleet of fully equipped work trucks, 24/7 on-call technicians, and a CognitoForms-based online work request system. The firm holds contractor licensing in nine states across the Southeast and Midwest and operates from at least seven branch offices, with safety credentials (ISNetworld, Browz) and NATE-certified technician staff supporting procurement eligibility with industrial and institutional buyers.
