The 2026 Contractor Missed Call Report: what 4.2M home-services calls revealed
27% of home-services calls go unanswered. We pulled the numbers from Invoca, Hiya, BIA/Kelsey and ServiceTitan to show what each missed call actually costs a contractor in 2026.
Twenty-seven percent of inbound calls to US home-services businesses go unanswered. The average residential plumbing emergency is worth $850 in same-day revenue, and the average HVAC after-hours call is worth $1,400. Multiply the gap times your monthly volume and the missed-call problem turns into the largest hole in most contractors' P&L.
This report consolidates the public data on what happens to home-services calls — answered, missed, voicemailed, called back — and what each outcome costs. Sources are listed inline; everything attributable is attributed. If you want the short version: missed calls cost most contractors more than rent.

Where the misses happen
The 27% missed-call rate is an average. The distribution is sharply non-uniform — three call windows account for most of the loss.
After-hours (6pm–7am). This is the largest single category. After-hours calls represent 35–45% of inbound volume for HVAC and plumbing (ServiceTitan 2026 panel data), and the pickup rate for traditional shops sits below 18% — most calls land on voicemail or roll to a sleeping dispatcher.
Lunch hour (11:30am–1:30pm). The second largest gap. A single-receptionist shop typically loses 60-70% of calls during the lunch window. Most contractors don't notice because the missed calls aren't logged anywhere.
Surge events (storms, heat waves, cold snaps). Roofing call volume after a hailstorm can spike 8-12× the rolling average for 72 hours. HVAC volume during a heat wave can hit 4-6×. Most shops are staffed for the average week, not the extreme week — so during the windows when the calls are worth the most, the pickup rate is the lowest.
What a missed call actually costs
The "average missed call costs $1,200" figure that circulates in trade press traces back to a 2021 Invoca analysis. By 2026 that number is conservative — ticket sizes have risen with material and labor inflation, and the value of an emergency call has grown faster than the average.
Updated ranges from ServiceTitan's 2026 dispatch dataset, by trade and call type:
| Trade | Routine call | Emergency call | Install / quote |
|---|---|---|---|
| HVAC | $185 | $1,400 | $7,200 |
| Plumbing | $220 | $850 | $4,600 |
| Roofing | $310 | $2,100 (storm) | $11,400 |
| Electrical | $190 | $720 | $5,800 |
| Landscaping | $145 | n/a | $3,200 |
| Remodeling | $420 | n/a | $24,000 |
These are revenue figures, not margin. But applied against a 27% miss rate and the typical 200–600 calls/month a mid-sized shop fields, the lost revenue across a year reaches mid-six figures for most operators — and seven figures for shops in storm-prone markets.
The HBR speed-to-lead trap
Even when contractors do catch up to missed calls, the math has already turned against them. The HBR speed-to-lead study (2.24M leads analyzed across multiple verticals) found that the odds of qualifying a lead drop ~60× when the callback comes more than 24 hours after the inbound call vs within the first hour.
For home services specifically, the curve is sharper. The 2026 industry rule of thumb — corroborated in ServiceTitan dispatch data — is that 5 minutes is the threshold. A homeowner who has a flooded basement at 11pm and gets a callback the next morning has already called two other contractors. The first to pick up usually books the job.
This is why the "we'll call them back tomorrow" pattern doesn't actually work. By tomorrow, the customer is your competitor's customer.
Why hiring out of the problem doesn't scale
The reflexive solution — "hire another phone person" — has stopped scaling in 2026. Three structural reasons:
Labor supply. The Bureau of Labor Statistics projects a 550,000-plumber shortfall by 2027. Adjacent roles (dispatchers, CSRs) face similar pressure. Even when the budget exists, the candidates often don't.
Cost. A single full-time phone staffer at $20/hour, 40 hours/week, 52 weeks/year = $41,600 in wages alone. Loaded cost (benefits, payroll tax, equipment) typically hits $52K–$58K. To get genuine 24/7 coverage you need three shifts — call it $160K/year in headcount alone.
Coverage gaps. Even with three staffers, the lunch, sick-day and turnover gaps remain. The math doesn't work for shops under $5M in revenue.
Where the recovery comes from
The structural alternative — pickup automation via voice AI — is what the $80B Gartner forecast is actually measuring. Avoca AI's $125M round at a $1B valuation in April 2026 (Kleiner Perkins-led, covered in Fortune and PRNewswire) signaled that the category had reached commercial maturity for home services specifically.
For a contractor running the numbers in 2026, the relevant comparison is no longer "AI vs human receptionist." It's "AI vs missed call." The lift from going from 73% pickup (human, business hours) to 100% pickup (AI, 24/7) on the worst-performing windows tends to recover 4-8× more revenue than the AI itself costs.
What to measure if you want to fix this
If you're a contractor reading this and trying to size your own miss problem, three numbers tell you most of what you need to know:
- Total inbound call volume per month — pull from your phone system (RingCentral, OpenPhone, OnSIP all expose this).
- Pickup rate by hour of day — most VoIP providers give a heat-map view. Look for the dead zones.
- Voicemail-to-callback conversion rate — what % of voicemails turn into a booked job? Below 25% means voicemail is functioning as a leak, not a backup.
Once you have those three, the cost of inaction stops being abstract.
FAQ
What's the source of the 27% missed-call rate?
Invoca's home-services platform aggregates inbound call logs across thousands of contractors and reports the figure annually. The 27% is the 2024–2026 rolling average across HVAC, plumbing, roofing, electrical and adjacent trades.
Is the $1,200-per-missed-call number still accurate?
The original 2021 Invoca figure was a vertical average. By 2026, blended emergency-call ticket sizes for HVAC and roofing are well above that. The ServiceTitan 2026 dispatch dataset puts the average residential HVAC emergency at $1,400 and the residential roofing storm-claim call at $2,100.
Do these numbers include after-hours?
Yes. The 27% includes all-hours volume. After-hours specifically runs higher — pickup rates below 20% are common for traditional shops without an answering service or AI.
Where do the survey populations come from?
ServiceTitan's panel includes ~7,000 contractor operators. Invoca's home-services dataset spans roughly 4.2M inbound calls/year. BIA/Kelsey's phone-leads-vs-web-forms research aggregates across multiple SMB verticals. Hiya's State of the Call survey is consumer-facing (88K US households).
How does Hi Agent measure against these numbers?
Hi Agent operates as the pickup layer. The shops running it sit at 100% answer rate by definition — every call gets answered. The variable becomes how well the agent triages: emergency vs routine vs quote, and how cleanly the booking lands in the CRM. That's what we benchmark, and that's what gets refined month over month.
