Hiller Plumbing, Heating, Cooling & Electrical

What Hiller Plumbing, Heating, Cooling & Electrical does

Hiller Plumbing, Heating, Cooling & Electrical is a privately held, founder-led residential and commercial home services company headquartered in Nashville, Tennessee. Founded in 1990 by Jimmy Hiller with $500 and a single pickup truck, the company has grown into a multi-trade service provider delivering plumbing, heating, cooling (HVAC), and electrical installation, repair, and maintenance through a dispatched field service model. Operationally it runs 18 regional branches across seven southeastern U.S. states (Tennessee, Southern Kentucky, Northern Alabama, Georgia, and Florida) supported by 600+ service vehicles and 850+ employees, with more than 1.5 million service calls completed since founding.

The company monetizes primarily through transactional, quote-based fees for on-site residential service calls, complemented by project and ongoing commercial service contracts in the operating states. Distribution is entirely direct: technicians are dispatched from regional branches in 500+ service vehicles to homeowner and business customers, with no franchise or third-party channel layer. Pricing is not publicly disclosed, but the company anchors demand with a 'Happy You'll Be or the Service is Free' service guarantee and JB Warranties-backed warranty coverage, plus flagship sports and entertainment sponsorships (University of Alabama Athletics, Ryman Auditorium/Opry Entertainment Group) that drive top-of-funnel awareness.

Growth is executed through a combination of organic branch openings (e.g., Birmingham, AL in 2024) and the acquisition of family-owned HVAC operators (Thompson Services 2018, Roussos Air Conditioning 2022, Gunn Heating & Air Conditioning 2024), with brands often retained post-close. Founder Jimmy Hiller remains the controlling figure and chairman-equivalent; the company is bootstrapped, has no identified institutional or private-equity backing, and augments its core operating footprint with the PRAXIS S-10 trade-contractor mentorship platform he co-founded.
