The numbers first, because trades owners deserve the math up front. During peak season, the average HVAC company receives 24 inbound calls per day. Industry data shows 62% of those calls go unanswered straight to voicemail. At an average service ticket of $340 and roughly $210 in expected revenue per inbound call, that's about $3,129 in lost revenue every single day. Over a four-month peak season, you're looking at $250,000–$375,000 walking out the door. Not to a competitor with better marketing. Not to a price war. To a voicemail greeting. Why this happens Your dispatcher is human. Your techs are on roofs and in crawlspaces. The 9 PM emergency call, the Saturday morning quote request, the lunchtime overflow nobody is physically available to answer. Hiring a CSR costs $35K–$45K/year and they still sleep at night. The fix: an AI voice agent A modern AI voice agent (we build on Vapi AI + Twilio) answers every call in under 3 rings, qualifies the job, checks your real CRM calendar, books the appointment, and texts the customer a confirmation. It logs the full call summary into Housecall Pro, Jobber, or ServiceTitan automatically. Deployment takes about 48 hours once CRM access is granted. Our client Anderson HVAC in Houston went from a 62% missed-call rate to zero and recovered $18K in the first month. The ROI math AI voice agent retainer cost: starts around $1,500/month as part of a full automation package. Revenue recovered for a typical $1M HVAC operation: $10K–$20K/month during peak. That's a 7–13× return before counting the review and follow-up automation that comes with it. If you want us to run this math with your actual call volume, book a free strategy call.
