The average HVAC or plumbing company misses 30-40% of incoming calls during peak season — techs are on a job, up a ladder, or under a sink, not near a phone. Each of those missed calls can be a $3,000-$10,000 job, and most callers who don't get an answer just call the next name on the list.

What it does:

1. Triggers the instant a call is missed (via Twilio webhook)

2. AI sends a short, personalized "sorry we missed you" SMS within seconds

3. When the customer replies, an AI agent holds the conversation — asking one question at a time until it has their name, the issue (leak, no heat/AC, install quote, etc.), address, and urgency (emergency vs. can wait)

4. Emergency jobs are flagged clearly so you can prioritize the callback

5. Once qualified, it automatically messages you on Telegram with the full job details

6. Every lead is logged and updated (auto-texted → qualified) in a Google Sheet

What's included:

• Full n8n workflow file (.json) — import and go

• Setup guide (this document + inline notes in the workflow)

• Ready-to-use Google Sheets lead-log template structure (includes urgency/job-type fields)

• Editable AI prompts for both the first text-back and the qualification conversation

Requirements to run it:

• A running n8n instance (self-hosted or cloud)

• A Twilio account with a phone number (SMS-capable)

• A free Groq API account for the AI conversation

• A Google account for the lead-log sheet

• A Telegram bot for instant owner notifications

No coding needed.
