This page walks through the complete ROI calculation for a hvac company deploying an AI voice agent. Use the framework to plug in your own numbers and project your specific return on investment.
Your starting numbers
For this hvac example, we'll use these baseline figures. Adjust based on your actual business:
- Average customer value: $480
- Missed-call rate: 28%
- Typical job range: $400-$1,800
- Monthly AI agent cost: $165
Step 1: Missed-call recovery
The biggest revenue lever for most hvac companies. Each missed call represents potential revenue that goes to a competitor who answers.
Assuming 50 inbound calls/day × 28% missed rate × 250 working days = 3500 missed calls/year.
With AI capturing 35% conversion on previously-missed calls: 1225 recovered customers × $480 = significant annual recovery.
Step 2: No-show reduction
For appointment-based hvac businesses, no-shows are a major revenue leak. AI reminder calls 24 hours before appointments reduce no-shows by 25-35%.
Step 3: After-hours capture
The 30% of calls that come outside business hours are the highest-value — they're often emergencies or urgent inquiries. AI captures them all.
Step 4: Total annual value
Combining all three revenue streams, a typical hvac company sees $50,000-$150,000 in annual value from an AI voice agent deployment.
Step 5: AI agent cost
At $165/month × 12 months = $165 * 12 = approximately $1980/year all-in.
Step 6: Net ROI and payback
With $50-150K annual value and $1980/year cost, the ROI is typically 20-50x with payback in 2-3 weeks.
