This report is for: owners of HVAC, plumbing, electrical, and roofing companies who suspect missed calls are costing them money but have never seen the number for their business. Below: the industry data, the per-trade math, and the formula to run your own figures in five minutes.
TL;DR: Across published industry research, 60 to 74% of calls to home-service contractors go unanswered, 85% of callers who reach voicemail never call back, and 78% of buyers hire the first company that responds. At reported average job values, $500 to $900 for an HVAC emergency repair, $300 to $800 for a plumbing emergency, $5,000 to $15,000 for a system replacement, a typical 3 to 5 truck shop missing 3 to 5 calls per working day loses $150,000 to $330,000 per year. That's not marketing you haven't done; it's customers who already called you. Sources, per-trade breakdowns, and the self-calculation formula below.
The five statistics that define the problem
Every number below comes from published industry research or vendor-published studies in the home-services category. We've noted the basis for each; treat vendor-published figures as directional ceilings, since vendors benefit from the problem being large, but the pattern repeats across enough independent sources that the shape of it is not in serious dispute.
- 60 to 74% of contractor calls go unanswered. Reported across multiple 2026 industry roundups; QuoteIQ cites 62% of after-hours HVAC calls going unanswered industry-wide, and AgentZap reports 67% of home-service calls unanswered overall. Crews are on job sites; the phone rings anyway.
- 85% of callers who hit voicemail never call back. Per research compiled by Invoca. A homeowner with a burst pipe doesn't leave a message, they call the next company on the list.
- 78% of buyers go with the first company that responds. Widely cited in home-services lead-conversion research. Speed isn't a tiebreaker; it's the whole game.
- Responding within 5 minutes makes you 100x more likely to qualify the lead than waiting 30+ minutes (Invoca-compiled research). After 30 minutes, lead quality collapses.
- 40% of HVAC and plumbing emergencies happen after 5 PM (AgentZap-reported). The highest-urgency, highest-value calls arrive exactly when staffing a human is least economical.
Per-trade revenue loss math
The formula is simple and conservative. We use working days (260/year), reported average job values, and a 65% close rate on answered calls (a standard industry assumption, your real close rate on live-answered calls is likely higher, since these callers have immediate intent):
Annual loss = missed calls/day × average job value × close rate × 260
HVAC
- Average emergency repair: $500 to $900 (use $650). System replacements: $5,000 to $15,000.
- 3 missed calls/day: 3 × $650 × 65% × 260 = $329,550/year at full value; even at a heavily discounted assumption that only 1 in 3 missed callers was a real buyer: ~$110,000/year.
- Peak multiplier: cooling season (May, September) and heating season (November, February) run 2 to 3x baseline call volume, so losses concentrate in the months you can least afford them. QuoteIQ's scenario math puts a solo tech missing 4 emergency calls/week at $10,400/month in peak season.
Plumbing
- Average job: $300 to $800 (ProfitLogic uses $387 as a conservative mean).
- ProfitLogic's published model for a $1.2M plumbing company: 3 missed calls/day → $196,287/year; 5 missed calls/day → $327,145/year.
- Emergency skew: burst pipes and sewer backups convert at premium rates, and per Estarta-reported figures, emergency home-service calls convert at 3x the rate of daytime calls.
Electrical
- Service calls: $200 to $500; panel upgrades and rewires run into the thousands (Hello Gubby-reported ranges).
- 3 missed calls/day at a $350 blended value: 3 × $350 × 65% × 260 = $177,450/year.
Roofing
- Inspection/repair calls: $300 to $800; full replacements: $8,000 to $15,000+.
- Roofing's loss profile is storm-driven: the 72 hours after a hail event produce weeks' worth of call volume. A roofer missing 20 storm-surge calls with even 2 converting to replacements forfeits $16,000 to $30,000 in a single weekend.
The compound effect nobody models
A missed call isn't one lost job. It's the lost job, plus that customer's future work, plus their referrals, plus the review they never leave, plus the marketing dollars you spent to make the phone ring in the first place. Industry analysts commonly apply a 3 to 5x lifetime multiplier to the immediate job value, which puts the true HVAC figure above closer to $330K, $550K/year for a mid-size shop.
Run your own number (5-minute version)
- Pull last month's call log. Count calls that went to voicemail, hung up, or rang out: M.
- Your average ticket: T. (If you don't know it, use the trade averages above.)
- Your close rate on live-answered calls: C. (If unknown, use 65%.)
- Monthly loss = M × T × C. Annual = ×12, then add 20 to 30% for seasonal peaks if you're in HVAC or roofing.
Example: 90 missed calls/month × $450 average ticket × 65% = $26,325/month ≈ $316,000/year.
If that number looks absurd, run the conservative version, assume only a third of missed callers were real buyers, and it's still $105,000/year. The conclusion survives very aggressive discounting.
What the solutions cost, relative to the problem
| Solution | Annual cost | Coverage | Hours covered/yr | Cost per covered hour |
|---|---|---|---|---|
| In-house receptionist | $45,000+ | Business hours only | 2,080 | ~$21.63 |
| After-hours human answering | $6,000+ | Evenings/weekends | 4,680 | ~$1.28 (quality varies) |
| AI answering (flat) | $600 to $5,400 | 24/7/365 | 8,760 | $0.07 to $0.62 |
| Full owned system (AI + dashboard + human agents) | Scoped, from $3,500 build | 24/7 + outbound + follow-up | 8,760 | Falls each year, you own it |
Solution costs from our AI Answering Service Pricing Index and ProfitLogic's published comparison. Against a $150K, $330K annual leak, every option on this table pays for itself, the question is which one fits how your shop actually runs.
Why this keeps happening (it's not laziness)
Contractors don't miss calls because they don't care. They miss them because the math of the job makes answering impossible: techs are under houses and on roofs, CSRs juggle dispatch and invoicing, call volume spikes 2 to 3x exactly when everyone is busiest, and 40% of emergencies arrive after the office closes. The industry built a staffing model for a phone pattern that no longer exists. The businesses fixing it aren't hiring harder, they're changing what answers the phone.
