The cost of a missed call isn't the same for every trade. A missed call to a locksmith is different from a missed call to a general contractor. Here's the math, broken down by home service industry.
Why "Missed Call Cost" Varies So Much
Before we get into the numbers, it's worth understanding why this varies: job values, conversion rates, and emergency probability all differ by trade.
A plumbing emergency call is almost certainly going to become a booked job if you answer it. A general contractor estimate request might convert at 30–40%. Factor in average job value, and the dollar cost of a missed call varies dramatically across home service trades.
The constant: 62% of callers who don't reach you will call a competitor and book with them.
The Cost By Trade
Plumbing — $280–$900 per missed call
Average plumbing job value: $350–$600 for service calls, $400–$1,500 for emergency work. Conversion rate if answered during emergency: 70–85%. Emergency calls are particularly high — the customer needs help now and will book with whoever answers.
An AI receptionist for plumbers capturing 5 additional emergency calls per month represents $2,000–$7,500 in recovered revenue.
HVAC — $350–$1,200 per missed call
Average HVAC service call: $200–$500. Full system replacement or emergency repairs: $1,500–$8,000. Maintenance contract value over 3 years: $450–$900. HVAC companies that miss seasonal emergency calls during heat waves and cold snaps lose disproportionately — those are their highest-margin jobs at their highest call volume.
AI answering services for HVAC companies handle surge call volume without anyone going on hold, regardless of how many calls come in simultaneously.
Roofing — $500–$3,000 per missed call
Roofing estimates average $5,000–$20,000+ for full replacements. Emergency tarping and storm damage calls convert at high rates — customers in crisis don't shop around much. A missed storm damage call can cost a roofer one of their highest-margin jobs of the season.
Electrical — $400–$2,500 per missed call
Electrical service calls range from $200–$600 for routine work to $3,000–$8,000+ for panel replacements and major installs. EV charger installations, solar connections, and whole-home generator hookups are high-value leads that convert well when the response is fast and professional.
Landscaping — $200–$800 per missed call (and up)
Individual landscaping service calls might run $150–$400. But a missed call for a seasonal maintenance contract — annual lawn care, monthly service, full landscaping programs — represents $1,500–$5,000 in annual recurring revenue. For landscaping companies, the missed call cost compounds over the lifetime of what would have been a recurring client.
General Contractors — $1,000–$15,000 per missed call
This is the highest-variance category. A missed inquiry for a kitchen remodel, addition, or commercial buildout could be a $50,000–$500,000 project. Even at a 20% conversion rate on a $200,000 project, a missed inquiry call costs $40,000.
The Weekly Math Most Home Service Businesses Don't Run
Here's a calculation most contractors don't do:
Take your average weekly call volume. Multiply by 62% (the percentage going to voicemail or unanswered). Multiply by 62% again (the percentage that call a competitor). Multiply by your average job value.
For a plumber getting 25 calls per week with a $400 average job:
- 15.5 go to voicemail or unanswered
- 9.6 call a competitor
- At $400 each: $3,840 per week lost
That's $199,680 per year quietly going to competitors — without the plumber ever knowing those calls came in.
What Changes When Every Call Is Answered
A 24/7 AI answering service for home service businesses doesn't capture every missed call perfectly. But it captures most of them — because answering a call is half the battle. The callers who would have hung up on voicemail now have a conversation, leave their information, and wait for your call-back.
The key change: you go from losing revenue invisibly to having a pipeline of warm leads with complete information, ready for follow-up.
For most home service businesses, the first month of 24/7 AI answering captures enough jobs to pay for the service many times over. The question isn't whether you can afford it — it's how much longer you can afford to let your competitors answer your calls for you.
