Trades & Home Services
AI Receptionist for HVAC, Plumbing, and Electrical Contractors
Home-services contractors miss 32 to 50% of inbound calls during peak season, per ServiceTitan industry benchmarks. Every missed call is roughly $300 to $1,800 in service revenue and $5,000 to $25,000 in install opportunity. After-hours emergency calls — burst pipe at 11pm, no heat at 2am, sparking outlet at 4am — are where the relationship is won or lost, and where most contractors lose them to a competitor who answered. The Ascero AI receptionist for HVAC, plumbing, and electrical contractors picks up 24/7, triages emergency vs. service vs. install, gathers system age and symptom data, and dispatches into ServiceTitan / Housecall Pro / Jobber with full context — while the owner sleeps.
Why HVAC contractor owners need this
The pain is specific. Generic call-answering services miss it. Below is the actual cost structure of an unanswered phone in trades & home services.
50% missed-call rates during peak season
ServiceTitan's 2025 contractor benchmark report puts inbound miss rates at 32% on a normal day and 48 to 55% during heat-wave or cold-snap weeks. The dispatcher is on three lines, the office manager is on hold with the supply house, and the customer who got voicemail is calling the next contractor on Google.
After-hours emergency calls hitting personal cell phones
A typical owner pays an estimated $500 to $1,500/month in personal sleep loss running the on-call line themselves — and still misses real emergencies because the phone tree is clunky and the triage is inconsistent.
Install leads (the $25K jobs) ghosting on voicemail
A new-furnace lead is $5,000 to $25,000. They Google three contractors at 8pm Sunday, call all three, and the first to call back gets the job. Voicemail is a guaranteed loss.
Service vs. install vs. commercial mis-routing
A commercial HVAC inquiry routed to a residential CSR is a 70% loss. The agent triages by call type, geography, system size, and SLA — and routes to the right team.
No system context captured on the first call
A tech rolling on a service call without system age, brand, symptoms, or address history wastes 30 to 60 minutes of windshield time. The agent captures all of it upfront and writes it into the ServiceTitan job ticket.
The math, for one operator
A 12-truck HVAC contractor doing $4.8M annual revenue, missing 42% of inbound calls during the May-September peak, with an average service call of $480 and 65 inbound calls per day during peak: roughly 27 missed calls daily, of which 45% would have converted at average ticket = $5,840/day, or roughly $876K in peak-season recoverable revenue. Even at a 30% recovery rate, that's $263K back to the P&L on a $48K subscription.

How the Twilio voice agent works
Tuned specifically for HVAC contractor call patterns. Not a generic call-answering bot.
- 1
Twilio voice agent answers 24/7 with the company greeting, in under two rings.
- 2
Triage classifier: emergency (active leak, gas, no-heat in winter, no-cool in heat advisory), service, install, commercial, billing.
- 3
Emergency calls dispatch directly to the on-call tech's phone with a structured summary; non-emergencies route to the next-morning service queue.
- 4
Service calls capture system age, brand, model, symptoms, address, and access notes, then book a dispatch slot in ServiceTitan / Housecall Pro / Jobber.
- 5
Install leads gather system type, age, square footage, and budget signals, then route to the comfort advisor with a same-day callback SLA.
- 6
Commercial calls escalate to the commercial sales team with a structured brief.
- 7
Spanish-language coverage built in for markets where it matters.

Live demo available on request — we'll provision a sandbox HVAC number you can call to hear emergency triage, service booking, and install qualification.
Compliance + scope
Call recording disclosed in the house greeting per state two-party-consent law where applicable. No customer payment data captured by voice — Stripe / Service Finance / GreenSky link sent via SMS for install deposits. EPA refrigerant-handling guidance is read-only; the agent never quotes pricing for regulated work without a tech site visit.

Does it integrate with ServiceTitan / Housecall Pro / Jobber?
ServiceTitan, Housecall Pro, Jobber, FieldEdge, and ServiceFusion are native integrations. The agent writes structured job tickets with all captured fields — customer, address, system, symptoms, urgency — directly into the dispatch board.
How does it handle emergency triage?
A configurable rules tree: gas smell, active water, no-heat below 50F outdoor, no-cool above 95F outdoor, sparking / smoke, sewage in living space = emergency. Everything else routes to next-morning. You set the exact thresholds for your business.
Will it wake the on-call tech for non-emergencies?
No. The agent's entire purpose is to take the on-call burden off humans. The on-call tech's phone rings only for confirmed emergencies. The agent dispatches everything else into the next-morning service queue.
Can it qualify install leads vs. service calls?
Yes — it routes by intent. "My AC is making a noise" goes to service. "I need a new furnace" or "my system is 18 years old and dying" goes to install / comfort advisor. The triage prompts are tuned per your business.
What if the agent dispatches a tech to the wrong job?
We tune mis-routing in the monthly review. Typical mis-route rate stabilizes below 3% by month two. For high-value calls we can require a human confirmation step before final dispatch.
Does it handle commercial calls?
Yes — commercial calls are detected (multi-unit, property manager, square-footage signals) and routed to your commercial sales team with a structured brief. The agent does not try to book commercial service slots automatically.
How fast can we go live?
Foundation tier is 14 to 21 days from contract. We need your dispatch software API, on-call schedule, emergency triage rules, service area map, and phone number to port.
