CallOS is a 24/7 AI receptionist and sales agent purpose-built for heating and cooling contractors. The platform answers every inbound call instantly, books or reschedules jobs against your techs' availability, and transfers complex issues to a human when needed. For HVAC operators, that means no missed no-heat calls in January and no missed AC calls in July, even when the phones are ringing off the hook.
What sets CallOS apart is its multi-agent architecture. Instead of a single AI answering calls, CallOS deploys six specialized AI roles that capture leads, dispatch jobs, generate quotes, coach CSRs, and follow up with customers end to end. The AI books jobs directly into your CRM, updates customer records, and keeps your dispatch board full automatically, and it can also place outbound calls for review requests and follow-ups after a visit.
CallOS markets itself as 90% cheaper than a human receptionist while delivering measurable results. Published HVAC customer data shows an average 12% increase in booking rates and 62% higher NPS scores within three months. CallOS ships with integrations into ServiceTitan and Housecall Pro, making it a strong fit for mid-market HVAC contractors already standardized on those platforms.
