Thimble is a digital-first commercial insurance provider built for small and micro-sized contractors. For HVAC shops, Thimble sells general liability limits of $1M or $2M, business owner's policies, tools and equipment coverage, and professional liability all through a fully online quote-to-bind flow. Rates are calculated based on ZIP code, crew size, policy period, and limits, which makes it attractive for newer HVAC operators who don't yet have annual revenue scale.
The signature feature is flexibility: an HVAC contractor can buy a one-day policy for a single side-job, a monthly policy during slow season, or an annual policy for a primary operation. Unlimited free additional insureds and instant Certificates of Insurance delivered to the contractor's inbox let techs meet last-minute property-manager or commercial GC requirements in minutes rather than days. Policies are backed by Arch Insurance after Arch Capital Group acquired Thimble in April 2023.
Thimble is especially well-suited to solo HVAC techs, seasonal installers, subcontractors on larger installs, and small shops that do occasional commercial work. The trade-off versus traditional carriers is fewer endorsements and less hands-on broker support, so established multi-truck HVAC companies with workers' comp and commercial auto needs typically pair Thimble with a carrier like biBerk, Nationwide, or Pie for a full program.
