biBerk is the direct-to-business digital channel for Berkshire Hathaway's insurance group, underwriting policies through Berkshire Hathaway Direct Insurance Company, National Liability & Fire Insurance, and Wellfleet Insurance. Founded in 2015 and headquartered at 1314 Douglas Street in Omaha, NE, biBerk was built to strip broker commissions out of small commercial insurance and sell directly to business owners. For HVAC contractors, that means rates are often 20%+ lower than what a traditional local agent could place through the same Berkshire paper.
The HVAC contractor insurance product covers all of the core lines: general liability, workers' compensation, commercial auto (single vehicle or fleet), business owner's policies, commercial umbrella, professional liability, and cyber. Quoting happens through a self-guided online flow that asks HVAC-specific questions (residential vs. commercial, rooftop work, refrigerant handling, payroll) and returns bindable prices in minutes. The underlying paper carries an A+ (Superior) AM Best rating, which satisfies even picky commercial GCs and property managers on certificate requirements.
biBerk is best for HVAC shops that know what coverage they want and prefer to transact online without an agent in the middle. The major trade-off is that because it's direct, there's no broker advocating for the HVAC shop at renewal or after a claim — customers report that audit-driven premium increases can be a surprise. For shops that want hand-holding, a specialty agency like HVACInsure is a better fit; for shops that value speed and savings, biBerk is the cheapest path to A+ Berkshire paper.
