Smith.ai is one of the longest-running virtual receptionist services in the market, combining AI automation with U.S.-based human receptionists to give home service contractors the best of both worlds. The HVAC offering uses AI to handle routine appointment scheduling and common questions about services and pricing, while live receptionists manage emergency service coordination, upset customers, and complex system discussions that require judgment.

Founded in 2015 and headquartered in Los Altos, California, Smith.ai has reached $26.7M in revenue with 3,000+ customers as of 2024. The platform offers AI Receptionist plans starting at $95/month with $2.40/call pricing over 50 calls, and live Virtual Receptionist plans from $292.50/month for 30 calls with $11/call over quota. Human escalation is included with every AI Receptionist subscription, so HVAC contractors can start with AI and hand off anything the bot can't confidently close.

Smith.ai supports 7,000+ integrations including ServiceTitan, Housecall Pro, Clio, MyCase, LawPay, Calendly, Acuity, Zapier, and Make, syncing conversations into the tools contractors already run. The service emphasizes transparent flat-per-call pricing with no charges for spam, wrong numbers, or robocalls, along with a risk-free 30-day money-back guarantee and month-to-month billing with no long-term contracts.
