Dr. Energy Saver

What Dr. Energy Saver does

Dr. Energy Saver, Inc. is a privately held home energy efficiency contractor network headquartered in Seymour, Connecticut, founded in 2009 by Larry Janesky as part of the Contractor Nation family of home improvement companies. The company provides residential home energy audits and a broad portfolio of retrofit services including insulation (spray foam, cellulose, blown fiberglass, rigid foam), air sealing, ductwork sealing and cleaning, heating systems (furnaces, boilers, geothermal, radiant, solar), cooling and dehumidification, air purification, water heaters, and replacement windows and doors. It also operates the Attic Systems division, launched in 2017 to address ductwork-in-attic and air-sealing problems. Underlying technical content centers on proprietary products such as TruSoft cellulose insulation (85% recycled, blown-in), Tight 'n True closed-cell foam duct encapsulation, the SuperAttic System, Mold-X2 remediation product, and SaniDry dehumidifiers, combined with a standardized whole-home energy audit that grades homes across ten distinct areas.

The business runs on a franchised dealer model rather than a direct-employed workforce. Customers request free estimates through the website or a national call center (1-866-632-5870) and are routed to locally-owned authorized dealers; the company reports 60+ branded locations across 28 states and over 450 dealers in its broader home improvement network, with 20,000+ homes serviced cumulatively through 2017. Dealers receive proprietary sales systems, software, training, and brand support, and the central corporate organization is small (11-50 employees). Revenue streams are professional services delivered by dealers plus central monetization through franchise/brand fees, training, and wholesale sale of proprietary products. The company is founder-controlled with no disclosed venture capital, private equity, or institutional investment, and it markets directly to consumers via its website, blog content, video content, customer testimonials, and a 'Become a Dealer' recruitment channel for home improvement contractors.
