Wintac
Wintac by Davisware is a legacy desktop software for HVAC, plumbing, and other field services. It consolidates scheduling, dispatch, customer records, job costing, and accounting in one system. Recurring service contracts are tracked with automated reminders. Integrated inventory management logs parts usage. While older in interface, it remains popular among smaller shops wanting an offline solution. Wintac suits small HVAC contractors seeking a stable, all-in-one local program without needing cloud functionality.
