DeLong Plumbing

What DeLong Plumbing does

DeLong Plumbing Heating and Cooling is a family-owned plumbing and HVAC service company headquartered at 1309 South Scenic Avenue in Springfield, Missouri, founded in 1991 by Garry and Molly DeLong and now led by the second generation of the DeLong family. The company operates from three physical offices serving Springfield, Lebanon, and Branson, plus 20+ surrounding communities across Southwest Missouri, with a team of 50+ employees comprising licensed plumbers, HVAC technicians, estimators, and support staff. It is recognized locally through an A+ BBB rating and nine consecutive years as the Ozarks Best Plumbing and HVAC company.

The business delivers residential and light commercial plumbing, heating, air conditioning, water treatment, indoor air quality, excavation, and 24/7 emergency services, supplied as a single integrated trade-services bundle rather than as a software platform or product company. Core capabilities are built on professional-grade equipment (hydro jetting, camera inspection, fully stocked service trucks) and licensed, uniformed field technicians dispatched from local offices. The company maintains authorized dealer partnerships with Carrier for HVAC equipment and Rinnai for tankless water heaters, and operates the Yellow Shield annual preventive-maintenance membership as a recurring-revenue layer over its predominantly transactional service base.

Revenue is generated primarily through professional services fees (service calls, diagnostics, labor plus parts) across plumbing, HVAC, and excavation, supplemented by hardware sales for water treatment systems and an annual subscription-style membership (Yellow Shield). The go-to-market model is direct-to-consumer, driven by 24/7 phone intake staffed by real people, online appointment requests, local SEO, and earned media from community involvement, Chamber of Commerce membership, and word-of-mouth referrals. Customer segments span residential homeowners (primary), commercial and business properties (offices, restaurants, schools, medical/dental, light industrial), and rural households on well water and septic systems, with a distributed base of more than 50,000 customers served over the company's 34-year history and no single anchor customer accounting for material revenue concentration.
