62-tech HVAC contractor lifts after-hours capture from 23% to 96% with a voice agent
"Northbridge HVAC" (name anonymized by the vendor) · Greater Boston, MA, US ·
What they did
After 5 p.m., calls used to hit a voicemail box cleared the next morning. A voice agent now qualifies each call (no heat, no cool, maintenance, estimate), writes a structured job into ServiceTitan, pages the on-call tech for true no-heat emergencies below 50 F, and queues a human callback by 9:15 a.m.
Reported results
- After-hours capture 23% to 96% in the first 30 days
- Booked jobs +41% versus the same period the prior year
- About 14 dispatch-supervisor hours a week reclaimed
- $1.4M 'recovered pipeline' in 90 days (vendor's calculation)
