Why Call Screening Matters More Than Raw Answer Rate
A lot of home service businesses focus on answering every call. That is important, but answering is only half the job. The second half is routing the call correctly — fast. A flooded basement job that waits 20 minutes for a callback is a job that goes to whichever company answers the phone next. According to data published by ServiceTitan, emergency water damage jobs carry an average ticket between $2,500 and $4,500. Misrouting one call per week can cost a restoration company more than $100,000 in annual revenue.
The challenge is that not every after-hours call is an emergency. On-call technicians burn out when they are woken up for scheduling questions or warranty callbacks. AI screening solves this by sorting calls into emergency and non-emergency buckets before any human is involved.
How Heyfield Tags Emergency Calls
Heyfield listens to the natural language a caller uses during the opening seconds of the call. It does not rely on the caller pressing a menu option — most panicked callers will not. Instead, the AI matches spoken words and phrases against a configurable trigger list tied to your specific trade. When a trigger phrase is detected, the system flags the call as urgent and begins the live-transfer sequence immediately.
The entire process from call pickup to technician connection takes under 30 seconds. Heyfield answers in sub-5 seconds, identifies the emergency signal, announces to the caller that it is connecting them to an on-call technician right now, and dials your designated on-call number. If the first number does not answer within a defined ring window, the system rolls to a backup number automatically.
Configuring Trigger Phrases by Trade
Emergency language is not the same across trades. A phrase that signals a life-safety emergency for a plumber means something different to a locksmith. Heyfield lets you configure trigger phrase sets per trade category during onboarding. Below are practical examples for each major trade.
Plumbing
- Gas leak, smell gas, gas smell
- Flooded basement, water everywhere, pipe burst, burst pipe
- Sewage backup, raw sewage, sewer smell inside
- No hot water (with modifier: baby, infant, elderly)
- Water heater leaking, tank leaking fast
HVAC
- No cool, no AC, AC is out (combined with temperature context: 95 degrees, heat index, baby, elderly, medical equipment)
- No heat, furnace out, furnace won't start (combined with freezing, pipes freezing)
- Carbon monoxide, CO alarm, CO detector going off
- Refrigerant leak, freon smell
Electrical
- Sparks, burning smell, electrical fire
- Power out to whole house (distinguish from utility outage via follow-up question)
- Outlet smoking, breaker won't reset after trip
- Flickering lights with burning smell
Locksmith
- Locked out with child inside, baby locked in car
- Break-in, door kicked in, lock broken after attempted entry
- Keys locked inside, car running with baby inside
Garage Door
- Door won't close, car trapped inside, can't secure garage
- Spring snapped, cable broke (vehicle blocked)
- Door fell off track, door fell down
Roofing
- Active leak, water coming in now, ceiling soaking
- Storm damage, tree on roof, hole in roof
Water Damage Restoration
- Flooding now, water rising, water won't stop
- Sump pump failed, basement flooding
- Pipe burst inside wall, water pouring from ceiling
What Happens After a Trigger Is Detected
Once Heyfield identifies an emergency trigger phrase, it follows a defined sequence:
- Confirm and calm: The AI acknowledges the emergency in plain language — something like, "It sounds like you have an active water emergency. I am connecting you to our on-call technician right now." This keeps the caller on the line and reduces hang-up rates.
- Collect minimum data: While initiating the transfer, the AI asks for the caller's name and address. This takes roughly 10 to 15 seconds and gives the technician job information before they even say hello.
- Live-transfer: Heyfield dials the on-call number and bridges the call. The technician hears a brief AI whisper — "Emergency call, water leak, caller is Jane at 412 Maple Street" — before the caller is connected.
- Fallback routing: If the primary on-call technician does not answer, the system tries a secondary number. If neither answers, the caller receives a callback commitment and the call is logged as a missed emergency with an immediate text alert sent to your designated manager number.
Non-Emergency Calls Are Handled Differently
Calls that do not trigger emergency phrases are handled by the standard Heyfield flow: appointment booking via Google Calendar integration, job type capture, and a follow-up confirmation sent to the caller. This keeps your on-call tech asleep for routine requests while guaranteeing they are reachable for real emergencies.
The separation is meaningful operationally. One published vendor benchmark from a field service scheduling platform found that 68% of after-hours calls to HVAC companies are non-urgent scheduling requests rather than true emergencies. Without screening, every one of those calls either wakes a technician or goes to voicemail — both bad outcomes.
Plan Considerations for Emergency Call Volume
Emergency screening is available on all Heyfield plans. Your call volume determines which plan fits your operation:
- Starter ($49/month): 150 minutes included, $0.25 per minute overage. Suitable for single-trade operators with modest after-hours volume, typically one or two emergency calls per week.
- Pro ($99/month): 400 minutes included, $0.20 per minute overage. Built for multi-tech shops or businesses in markets with frequent weather events that drive emergency spikes.
- Business ($199/month): 800 minutes included, $0.15 per minute overage. Designed for multi-location or multi-trade businesses where emergency routing complexity is higher and call volume is consistent.
Emergency calls tend to run longer than scheduling calls — a panicked caller needs more reassurance and more information collection. Budget roughly 3 to 5 minutes of AI call time per emergency interaction when estimating your monthly minute usage.
Setting Up Your Emergency Routing Configuration
During the 7-day free trial — no credit card required — you configure your emergency trigger phrases and on-call routing directly in the Heyfield dashboard. The setup process involves three steps: selecting your trade category to load a default trigger phrase library, editing or adding phrases specific to your service area or common job types, and entering your on-call rotation numbers in priority order. Most operators complete this in under 15 minutes. Changes to trigger phrases or on-call numbers take effect immediately, which matters when your rotation changes weekly.
