Why HVAC pros choose Bit & Grain.

Service to install, one tool for both modes

HVAC bounces between emergency service runs (route + service log + parts) and multi-day installs (estimates + supplier orders + change orders + final commissioning). Bit & Grain handles both modes, owner-operators and small HVAC crews running 1 to 5 person businesses get the same surface as bigger shops.

Every HVAC workflow in one place

Service tickets, install estimates, supplier orders, maintenance-contract scheduling, AND seasonal tune-up routes, without bouncing between Housecall Pro, QuickBooks, a manufacturer portal, and a paper tag-and-bag system.

AI handles the receipt and parts grind

Snap a photo of any supply-house receipt and Grain AI logs vendor, amount, items, and maps each line to the right job. Less time on the dashboard at the end of the day, more billable hours and clean tax-ready books.
