Description

CallBack HVAC is a follow-up tool for HVAC shops that miss calls while technicians and office staff are busy. With a compatible phone route and an approved texting number, a caller who reaches a supported unanswered-call outcome hears a consent prompt. If they press 1, the system can send one service text. The owner reviews any reply and makes the callback; the software does not answer every call or book jobs for you. The core plan includes caller records, a callback queue, message templates, lead status, basic reporting and CSV export. One dashboard reply is allowed after an incoming customer text. Staff must continue to handle booking and ongoing customer contact. AI CSR call handling is a separate pilot subject to review and activation, not part of the base trial. Core software costs $149/month after a 14-day trial that starts when the email address is confirmed. No card is required to start the software trial. Setup and carrier review use trial time. Provider number rental, registration, voice calls, messages and carrier fees are additional, including during the trial. Twilio is the standard setup; Telnyx and Plivo need availability confirmation before selection. A successful call-and-text test is required before customer use.
