AI HVAC & Plumbing Lead Qualifier to Telegram (n8n Webhook + OpenAI)

Turn AI-classified HVAC & plumbing leads into instant Telegram dispatch alerts (n8n + OpenAI)

This n8n workflow receives inbound HVAC & plumbing enquiries via a webhook, uses OpenAI to classify and structure the request, and immediately routes genuine customer leads to Telegram—plus a separate emergency alert for on-call technicians.

What this workflow does

• Receives enquiries via webhook: A POST request hits the n8n Webhook Trigger. The workflow instantly returns a JSON confirmation response.
• Builds an enquiry text block: It collects submitted fields (e.g., name, phone, email, address, message) into a single text block for analysis.
• Uses OpenAI to classify and summarize: Sends the enquiry text to OpenAI and parses the response into structured fields such as trade, job type, urgency, missing information, and a suggested reply.
• Stops non-customer messages: If the inbound message is not a genuine customer enquiry (e.g., marketing offers or job applications), processing halts.
• Creates a dispatcher-ready brief: Includes classification, summary, missing details to ask for, and the customer contact information.
• Routes to Telegram: Sends the brief to dispatch. For emergencies, it alerts the on-call technician with a separate Telegram notification.

Use cases

• A website form submits HVAC repair requests: the workflow classifies urgency and sends a structured dispatch message to your team via Telegram.
• After-hours emergency calls: the workflow triggers an on-call Telegram alert while non-emergencies route to standard dispatch.
• Mixed inbound sources: phone intake tools or email parsers can POST to the same webhook, and OpenAI ensures consistent structured lead summaries.
