OpenPhone is a modern, app-first business phone service built for small and growing teams. It runs entirely in the browser and on mobile, letting an HVAC owner, dispatcher, or tech make and receive business calls and texts from their personal device without needing desk phones.
For residential HVAC shops and newer contractors, OpenPhone is attractive because onboarding is measured in minutes, not weeks, pricing is transparent, and the mobile app keeps customer communication centralized. Shared numbers mean the dispatcher, the lead tech, and the owner can all see and respond to the same inbound customer thread.
Integrations include HubSpot, Salesforce, Gong, Slack, and Zapier, along with an open API and webhooks that let HVAC owners wire OpenPhone into tools like Housecall Pro, Jobber, or ServiceTitan via automation.
