Home Services Missed Call ROI Calculator
How much revenue is your HVAC, plumbing, or landscaping company losing to missed calls? Use this framework to calculate monthly missed-call revenue and voice AI ROI.
Every home services contractor loses revenue to missed calls, but almost none know how much. This guide walks through a practical ROI framework for HVAC, plumbing, and landscaping companies, using benchmarks that reflect the reality of the phone during peak season.
Step 1: Calculate your monthly call volume
Pull the last 90 days of inbound calls from your business phone provider. Divide by 3. That is your baseline monthly call volume. Add 20 to 40 percent for peak-season months (summer HVAC, winter no-heat, first-snow, spring lawn quote).
Step 2: Estimate your miss rate
Most home services contractors miss between 25 and 40 percent of calls, higher during peak season. Miss rate includes voicemails, busy signals, and calls that ring out unanswered.
Step 3: Estimate revenue per booked call
Use this rough benchmark by service type:
- HVAC service call: $200–$600
- HVAC install/replacement: $5,000–$15,000
- HVAC maintenance plan (annual): $300–$700
- Plumbing service call: $200–$800
- Plumbing emergency: $500–$2,500
- Lawn care seasonal contract: $800–$3,000
- Snow removal seasonal contract: $1,000–$5,000
- Commercial landscape contract (annual): $30,000–$300,000
- Commercial HVAC contract (annual): $50,000–$500,000
Step 4: Calculate lost monthly revenue
(Monthly call volume) × (Miss rate) × (Booking conversion rate) × (Avg revenue per booked call) = monthly missed revenue.
For a typical HVAC contractor with 800 calls/month, 30% miss rate, 40% booking rate on missed calls that would have been recovered, and $350 average service ticket, that is 800 × 0.30 × 0.40 × $350 = $33,600 in monthly missed revenue.
Step 5: Compare voice AI to alternatives
- Full-time CSR: $35K-$50K/year, no nights or weekends.
- Traditional answering service: $500-$1,500/month, only takes messages.
- Voice AI receptionist: flat monthly rate, books directly, 24/7 coverage.
The bottom line
Most home services contractors are losing $8K–$30K a month to missed calls. A voice AI receptionist recovers a large portion of that at a fraction of the cost of a full-time CSR.
