For HVAC Contractors — $2M to $8M Revenue
One in four calls to the average HVAC shop goes unanswered. When that happens, fewer than 3% of callers leave a message — most hang up and dial the next company on the list. And 85% of them never try you again.
Cenrai puts an AI on your phones that picks up before voicemail has a chance to kick in, figures out what the caller needs, and gets the job on your dispatch calendar. Day or night, slow season or the middle of a heatwave. Your phones are covered.
These aren't edge cases. They're jobs walking out the door every week.
Tuesday night, peak season
A homeowner's central air goes out. They call you first — your truck was in their neighborhood last summer. They get your voicemail. Within 90 seconds, they've found another company on Google. That company answers. By 8 AM, a competitor's tech is in their driveway.
Estimated loss: $7,500–$12,500 replacement + lifetime customer value
End of week, your team is in the field
A property manager calls about a rooftop unit. Nobody's available. You call back Monday morning. They already went with someone else — a company that responded Friday evening. Research shows ~78% of customers buy from whoever responds first.
Estimated loss: $18,000–$35,000 commercial job
Spring replacement season
A homeowner got a quote for a full system replacement and wasn't ready to commit. Nobody followed up. A competitor sent one reminder in April. They booked that week. The job was yours until it wasn't.
Estimated loss: $7,500–$12,500 system replacement
The system Cenrai installs
Cenrai's AI answers every inbound call before it reaches voicemail — day or night, weekend or holiday, peak season or slow season. It qualifies the caller the way a trained CSR would: new or existing customer, emergency or routine, system type and age, residential or commercial. Then it books the job directly into your dispatch calendar — ServiceTitan, Housecall Pro, Jobber, or your existing scheduling tool. True emergencies get an immediate human handoff with a live call summary already written.
See How It Works →Four mechanisms. Installed in 48–72 hours, guaranteed within 7 days. Running without you.
01 — 24/7 AI Call Capture
Every call answered before it reaches voicemail, around the clock
The AI answers every inbound call before it goes to voicemail — not after a hold queue, not after rings pile up unanswered. It qualifies the job using your criteria (emergency vs. routine, system type, service area), handles standard FAQs, and books directly into your dispatch calendar with no manual re-entry. True emergencies get an immediate human handoff with a live call summary already written.
02 — Speed-to-Lead Automation
Sub-60-second response to every missed call and web form
For any call that slips through during a simultaneous inbound surge, a text goes to the caller in under 60 seconds. Web form submissions get an immediate AI response. The MIT and InsideSales Lead Response Management Study — 15,000+ leads across 100+ companies — found that responding within five minutes makes you 21× more likely to qualify a lead than waiting 30 minutes. We operate in seconds, not minutes.
03 — Dormant Customer Reactivation
AI campaigns across your existing database
The average HVAC customer needs maintenance between installations and faces full system replacement every 10–15 years. Customers you've already earned are far easier to re-engage than cold prospects — they know your work. Cenrai segments your existing database by equipment age, last service date, and job type, then runs AI reactivation campaigns automatically across SMS, email, and voice.
04 — Persistent Follow-Up
Multi-touch sequences that run automatically
A quote sent without follow-up is rarely a job won. Cenrai maintains an AI-driven follow-up sequence on every open estimate, every new lead, and every dormant contact — timed, personalized, and consistent. Research shows roughly 42% of campaign replies come from follow-ups, not the initial message. Your team does nothing. The leads that were quietly dying in your CRM start responding.
We take your call volume, your typical response time, and what your average job is worth. Then we run the math and show you what that adds up to in lost revenue every month — and what it looks like when it stops. No pitch. No pressure. Just your number.
