Why After-Hours Leads Matter

The highest-conversion setup is instant missed-call text back + triage questions + next-day booking handoff. It beats voicemail-only and costs less than full call center coverage.

After-hours leads are often higher urgency and higher ticket. If your first response is slow, they call the next company.

1. Send Instant Missed-Call Text Back

When a call is missed, send a text in under 30 seconds: acknowledge, ask urgency, ask equipment type, and ask preferred callback window.

Script: "Sorry we missed your call. Is this no-cool/no-heat urgent right now?"

2. Use a 4-Question Triage Script

Collect only what dispatch needs: urgency level, issue type, address/zip, and availability. Keep it concise.

3. Split Emergency vs Non-Emergency Paths

Emergency path routes to on-call tech or escalation. Non-emergency path offers next available slots automatically.

4. Confirm the Next Step in Writing

After triage, send explicit next step: "Tech arrival window" or "office callback at 8:30am". This reduces repeat inbound calls.

Copy/Paste Template: Missed-Call SMS

1) **Instant text-back:** "Thanks for calling [Company]. Sorry we missed you. Is this urgent no-cool/no-heat right now? Reply YES for urgent."

2) **Non-urgent follow-up:** "Got it. We can get you scheduled for [time window]. Reply with your address + best callback number."

3) **Next-step confirmation:** "You are confirmed for [date/time]. If anything changes, reply to this message."
