HVAC contractor in Laval recovers$5,400/mo in after-hours calls
A scenario showing the math when an Alizé AI receptionist handles after-hours emergencies for a typical $400K-revenue HVAC business in Laval.
ROI scenario, not a testimonial
This is a transparent ROI scenario built from public industry data (Statistics Canada, BBB, Service Canada wage tables, average ticket sizes from HVAC trade reports). It models the math a typical Laval HVAC contractor would see after deploying Alizé AI. No customer is named — but all inputs are auditable.

The leakin the funnel
A typical Laval HVAC contractor receives 30 after-hours calls per month — split roughly 50/50 between French and English speakers. Of those, voicemail captures ~40% (some leave a message), but the average response time is 9-14 hours. By then, 7 out of 10 voicemail leavers have already called the next contractor on Google.
That leaves ~12 calls per month captured and converted (40% answer × 75% close rate = 30% net), and ~18 calls lost to voicemail decay or language mismatch (the owner does not speak fluent Quebecois French).
18 lost calls × $450 average ticket × 30% close rate the next contractor probably won by language and speed = ~$2,430/month in lost emergency revenue. Plus the non-emergency follow-up jobs that would have come from those customer relationships over 12 months.
The 30-daymath after Alizé AI
Same call volume. Same average ticket. Different coverage layer.
| Before Alizé | After Alizé | |
|---|---|---|
| After-hours calls answered | ~40% (voicemail catches some) | 100% (24/7 AI) |
| Avg response time | 9-14 hr (morning callback) | < 30 sec |
| French calls handled in French | Owner switches to English | 100% in Quebecois French |
| Emergencies escalated to owner | Whenever owner sees voicemail | Instant SMS + ring on personal line |
| Monthly emergency conversions | ~12 jobs × $450 = $5,400 | ~24 jobs × $450 = $10,800 |
| Monthly recurring cost | $0 (voicemail) | $99/mo (Starter Team plan) |
| Net monthly revenue impact | — | +$5,301/mo ($10,800 − $5,400 − $99) |
Net result: an extra $5,301/month in captured revenue at a $99/month software cost. That is a 53× ROI on the Starter Team plan — without adding a single hour of the owner's time.
