Summer heatwaves
No-cooling calls arrive all at once. Every caller gets an instant reply and the same triage questions. Routine jobs go into real open slots; emergencies go straight to your on-call technician.
Zynvox for HVAC companies
Never lose another call to your HVAC company.
No-cooling and no-heat calls answered and booked before the customer calls the next company.
In short
Missed-call automation for hvac companies.
Zynvox answers every missed call to your HVAC company within seconds — by text or AI voice — qualifies the caller, books the appointment, updates your CRM and sends reminders, 24 hours a day. Heating and cooling emergencies are urgent, so the customer calls the next company on the list the moment nobody answers.
For HVAC companies
Built for the way HVAC calls really come in.
HVAC demand is seasonal and spiky. The first heatwave or cold snap of the year brings a wave of calls in a single day, and most arrive while your technicians are already on jobs. Zynvox answers every caller in seconds, separates real emergencies from routine work, and keeps your calendar full between the peaks.
Winter cold snaps
No-heat calls at night are triaged straight away: furnace not igniting, no heat with children or elderly people at home, or a gas smell, which gets a “leave the house and call 911 or your gas company” instruction first.
Spring and fall tune-ups
Customers who opted in get maintenance reminders at the right time of year. That keeps technicians busy between peaks and turns one-off repairs into repeat customers.
Emergency rules you can set
Emergencies are escalated to a person straight away, never booked into a later slot.
- No cooling above a temperature you choose
- No heat below a temperature you choose
- Children, elderly or medically vulnerable people in the home
- Water leaking from the indoor unit
- Gas smell or carbon monoxide alarm: 911 first, then your team

Example
What the caller sees.

Our AC stopped blowing cold air and it’s 90 degrees inside.
Sorry about that — we can help tonight. Is anyone at home who is elderly or unwell? And what’s the service address?
Questions
HVAC companies: FAQ.
What does Zynvox do for hvac companies?
When a call to your HVAC company is missed, Zynvox replies in seconds by text (or answers by AI voice), qualifies the caller, books the appointment, logs everything to your CRM and sends reminders — 24/7.
Can Zynvox handle after-hours HVAC emergencies?
Yes. It answers or texts back within seconds at any hour, and books routine visits. Anything your rules call an emergency goes straight to your on-call technician — by call and text — instead of into a later slot.
Does it work with our field-service software?
Zynvox logs each job to your CRM or field-service system. We confirm the exact integration for your stack on the analysis call.
What does Zynvox ask an HVAC caller?
What the system is doing (no cooling, no heat, noise, leak), whether anyone vulnerable is at home, the service address, and whether they want the first available slot or a specific time. You can add your own questions.
Can it tell a tune-up from an HVAC emergency?
Yes. You set the rules — for example, no cooling above 90°F with children at home is an emergency, while a noisy outdoor unit is routine. Emergencies go to your on-call technician; routine work is booked into open slots.
Does Zynvox quote HVAC repair prices?
Only the prices you approve, such as your diagnostic or emergency call-out fee. Repair prices are left to the technician on site.
How quickly can we go live?
It starts with a 20-minute analysis call, where we map your call flow and calculate your missed-call revenue leakage. We then configure Zynvox on your existing business number.
