Sources: the booking rate is ServiceTitan's own, from its report on call booking rates across more than 3,000 trade businesses in the United States and Canada; the 2 figures beside it are from ServiceTitan's 2026 State of AI in the Trades, a survey of 1,032 contractors across HVAC, plumbing, electrical, roofing, garage door, pest control and commercial landscaping. The 3 figures that used to sit here are gone rather than dressed up: the 62 percent missed call figure was credited to a publisher that has never published it, the 78 percent figure is not in the study it named and that study's site is now a paid link farm, and the $4,200 job value had no source at all.

Why this hits Detroit, MI shops in particular
The local shape of the problem here is same-night furnace and boiler repairs. That matters because the shops losing this fight are almost never losing on the quality of the work. They are losing in the gap between somebody searching and somebody being spoken to.
The pattern repeats in three ways, and all three are worse for an owner-operated shop:
- The call arrives when nobody can take it. A homeowner with water on the floor or no heat rings in the evening, at the weekend, or in the middle of the job you are already on. That is precisely the window in which a small shop has nobody free to answer, and the homeowner is working down a list.
- The estimate goes out and then goes quiet. Most trade work is quoted and then decided days later. A quote nobody follows up sits against two other quotes that also went quiet, and the job goes to whichever shop happened to make contact again first.
- The finished job never becomes a review. Search ranking and the homeowner's shortlist both turn on reviews, and a review only exists if somebody asked for one while the customer was still pleased. Asking by hand after a long day is the task that never happens.
The honest arithmetic: an answering service or AI voice agent for a trade shop runs roughly $150 to $500 a month. At the job values in this trade, one recovered call pays for months of it. The decision is not close, which is why this page spends more time on the order to build things in than on whether to build them at all.
What this looks like in Detroit, MI
Detroit winters bring dangerous cold that makes a failed furnace an emergency. When heating stops, indoor temperatures drop fast. Families cannot wait until the next business day for service. They expect help immediately, and they call the first company they find. Service firms that cannot answer those calls quickly lose the customer to someone else. In Detroit, a missed call during the coldest period means that customer is gone for good.
Detroit has a large number of older homes with aging heating systems. Boilers and furnaces in these properties have worked through many harsh winters. Components wear out and fail without warning. When that happens, the occupant needs service right away. The homeowner will not shop around for the best option. They need heat restored, and they need it now. If the first call goes unanswered, they move on immediately.
The supply of qualified heating technicians in Detroit does not match the demand during peak cold. Every service company faces the same shortage of skilled workers. When temperatures drop and many systems fail at once, firms struggle to keep up with incoming calls. Some customers will wait, but many will not. The company loses that job and the relationship that might have followed. The work goes to whoever answers the phone first.
The cost to a Detroit heating business of a slow or missed call is significant. Lost revenue from that single job is only the beginning. The firm must then spend more to attract a new customer. Meanwhile, the jobs that are taken tend to be emergency repairs with slimmer margins. Over time, both revenue and profit shrink. The business works harder but earns less, and competitors who respond faster grow stronger.
In Detroit, the business trains staff to handle the most common furnace models found in older homes. They keep a fleet of vehicles ready for immediate dispatch during cold snaps. The business also offers after-hours emergency services to cover nights and weekends. This ensures that customers are not left without heat when temperatures plummet.
If the phone isn't answered, Detroit residents quickly move to the next option on their search list. They value a quick response over detailed explanations. Competitors who answer promptly and provide upfront cost estimates win the customer's business immediately. In Detroit, where urgency is key, the company that engages quickly often gets the job.
- Detroit winters create urgent heating emergencies. When a furnace stops working in severe cold, occupants need help immediately. They call the first company they find and move on quickly if no one answers.
- Detroit has many older heating systems that fail without warning. Aging boilers and furnaces break down during the coldest periods. Residents will not wait for a callback when their home has no heat.
- Slow response costs Detroit heating businesses. Each missed call is lost revenue and a lost customer. The firm then spends more on marketing to replace that work, while profit margins shrink.
What this looks like on a real Detroit, MI call
Before
A homeowner calls at a quarter to eight in the evening. Voicemail. They leave a message, or more often they do not. Your office manager finds it at eight the next morning, calls back, and gets somebody who booked another shop the night before. Nothing about your work was ever compared to anybody else's.
After
The same call reaches an AI voice agent. It asks whether there is water running, whether there is heat, whether the power is off, records the address and the fault, and texts the on-call technician a summary inside a minute. The technician calls back at eight fifteen. The job is on the board before the morning meeting.
The right build for each trade
Plumbing
- The after-hours emergency call is answered, triaged for urgency and dispatched to the on-call technician rather than left on voicemail
- Estimate follow-up runs by text on its own, because a homeowner deciding on a repipe or a water heater decides days after the visit
- Recurring work such as a water heater flush or a winterisation goes out as a scheduled campaign instead of being remembered by nobody
Heating and cooling
- During a heat wave or a cold snap the phone is answered by something that does not queue, so the overflow becomes booked jobs rather than lost ones
- Maintenance agreement renewals are chased automatically, which is the part of the book that quietly lapses when everyone is busy
- New system enquiries get a follow-up sequence that books the in-home consultation without a salesperson chasing it
Electrical
- Inbound work is qualified for job size, timeline and whether a permit is involved before it reaches your schedule
- Panel upgrade and car charger quotes get an automatic follow-up carrying the financing options, which is what most of the silence is actually about
- The review request goes out within hours of the job closing, while the customer is still standing in a house that works
Roofing
- Every storm damage enquiry is captured and triaged by area and urgency, including the ones that arrive all at once
- A multi-touch follow-up sequence runs across the whole decision window, because roofing is decided over weeks and not over a phone call
- The insurance conversation gets a prepared first reply, which is the point at which most homeowners stall

The first 30 days, in order
- Day 1. Put answering on your main line after hours. Nothing custom, nothing integrated, a forwarding number and a script. This alone recovers the calls you are losing tonight.
- Week 2. Connect the job management software you are already paying for to an estimate follow-up sequence. Every quote gets chased on its own, in your words, without anybody remembering to.
- Week 4. Turn on the review request on job close. It costs almost nothing, it runs forever, and it is the only item here that keeps paying after you stop looking at it.
Only after those three are running does a custom build make sense, and it makes sense for a specific reason: several locations or subcontractors to dispatch across, permit dependent scheduling, or a call flow your job management software cannot represent without somebody retyping everything. Until then a custom build is an expensive way to do what a forwarding number already does.
