Nationwide is one of the largest commercial insurance carriers in the United States, founded in 1926 as the Farm Bureau Mutual Automobile Insurance Company and headquartered at One Nationwide Plaza in Columbus, OH. Its commercial lines division writes HVAC contractor programs through an independent agent channel, bundling general liability, commercial property, business income, workers' compensation, commercial auto, inland marine (tools and installation floater), umbrella liability, and cyber into tailored packages for residential and commercial HVAC shops.
Where Nationwide differentiates from digital-first carriers like biBerk and NEXT is in its surety bond capacity. HVAC contractors doing new construction, government, or large commercial work increasingly need performance, payment, bid, license, and fidelity bonds — Nationwide writes all of them, along with contractor's license bonds required by city and state authorities. For a growing HVAC company chasing bigger projects, Nationwide can serve as a one-stop shop for both P&C coverage and the bonds required to get on the job site, which is something that most direct-to-consumer digital carriers can't do.
Nationwide's HVAC program is delivered through independent insurance agents, so pricing, program design, and service all depend on the broker an HVAC owner chooses. That provides more hand-holding and re-marketing flexibility than a direct channel but also slower quote turnaround and less transparent pricing. Nationwide is best for established multi-truck HVAC shops with commercial customers, bonded projects, and complex fleet and property exposures — not for one-truck operators who mostly need fast GL online.
