AI Phone Answering for San Antonio HVAC Contractors

Triple-digit summers and hard water put HVAC systems under constant load. Thermoi answers every call 24/7, books appointments, and sends you the caller details and a full transcript.

Answered 24/7, never voicemail24/7 emergency coverageOne setup call, nothing to install

Built for the way San Antonio HVAC calls actually come in

San Antonio summers push AC systems hard, and the region's hard water shortens equipment life, so service and replacement calls stay steady. When a system quits during a heat advisory, the first contractor to actually answer usually wins the job.

Peak demand in San Antonio runs May through September, and that is exactly when calls overflow and go to voicemail. Thermoi picks up every one, takes the address and the problem in the caller's own words, and books the job when there is one, so a busy season stops meaning lost work.

Every call answered

No more voicemail during a San Antonio heat wave or cold snap. The AI picks up on the first ring, 24/7.

Booked on the spot

The AI agrees a time with the customer while they are still on the phone, and the booking lands in your Thermoi dashboard with the service address and arrival window.

The address, the callback number and what the equipment is doing, in the caller’s own words, by email and Slack when the call ends.

San Antonio summers push AC systems hard, and the region's hard water shortens equipment life, so service and replacement calls stay steady. When a system quits during a heat advisory, the first contractor to actually answer usually wins the job. Thermoi answers every call 24/7, so the jobs that used to hit voicemail get qualified and booked instead.
Yes. When a system fails after hours the call gets answered instead of going to voicemail. Sara takes the caller's name, number, service address and what the equipment is doing, and books a time if they want one. When the call ends the summary and the full transcript are in your dashboard, and you can have them emailed or posted to Slack. Nothing in the product decides for you whether a call is an emergency, and there is no SMS or automated callout — you read the caller's own words and choose who goes first.
You define your service area. The AI handles calls from across the San Antonio metro, including New Braunfels, Schertz, Converse, Boerne, Seguin.
Setup is one call. We configure the agent with your business name, services and service area, and you forward your number when you are ready. There is no technical setup on your end.
