How to write urgency rules for your answering service

How to decide which calls are emergencies, the phrases to list for common trades, and how to set on-call windows so urgent calls reach a person.

Updated October 17, 2026

In short

Write the words your customers actually say, not categories: "no heat" rather than "HVAC emergency". List five to ten phrases, set an on-call window with a primary and a backup, and review the list after a week of real calls. The AI also uses judgement on calls that sound urgent even when no phrase matches.

Start from real calls

Look at last month's after-hours messages and voicemails. The emergencies use the same handful of phrases every time.

Phrase lists by trade

HVAC: no heat, no AC, smell gas, carbon monoxide. Plumbing: burst pipe, water everywhere, sewage backup, no water. Electrical: no power, sparks, burning smell. Locksmith: locked out, child in car. Property management: no heat, flooding, locked out, gas.

  • HVAC — no heat · no AC · smell gas
  • Plumbing — burst pipe · water everywhere · sewage backup
  • Electrical — no power · sparks · burning smell
  • Locksmith — locked out · child in car
  • Property management — flooding · no heat · gas

Windows and escalation

Set the hours someone can actually respond. Add a backup. Choose how many minutes to wait before escalating; ten is typical.

Review weekly

Add phrases from calls that should have been urgent; remove ones that paged you for nothing.

Common questions

What if a caller is upset but not in an emergency?

The AI takes a message with the urgency flag off and promises a callback; you decide in the morning.
