AI Phone Answering for Denver HVAC Contractors

Cold winters and big day-to-night swings load both furnaces and AC. Thermoi answers every call 24/7, books appointments, and sends you the caller details and a full transcript.

Built for the way Denver HVAC calls actually come in

Denver gives HVAC contractors two busy seasons: hard winters that strain furnaces and dry summers that have pushed more homeowners to add cooling. The wide daily temperature swings at altitude keep systems cycling, and a no-heat call in a January cold snap cannot wait for a morning callback.

Peak demand in Denver runs December through February and July through August, 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 Denver 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 2 AM call comes back with details

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.

Denver HVAC Contractors Ask...

Denver gives HVAC contractors two busy seasons: hard winters that strain furnaces and dry summers that have pushed more homeowners to add cooling. The wide daily temperature swings at altitude keep systems cycling, and a no-heat call in a January cold snap cannot wait for a morning callback. 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 Denver metro, including Aurora, Lakewood, Arvada, Centennial, Boulder.
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.
