Emergency call triage for a regional HVAC firm

Out-of-hours calls went to an answering service that took messages. They are now triaged by urgency and dispatched to the nearest engineer carrying the right parts.

Problem

A message taken at 2am is not a dispatch

Brightflow covered 400 commercial contracts across three counties. Out of hours, an answering service took a name and a number. The on-call engineer picked up messages when they woke, by which point some sites had been without heating for six hours.

Approach

Triage first, then match to a van

The agent asks a short structured set of questions, classifies the fault and assigns an urgency band against the contract SLA. It then matches the job to the nearest on-call engineer whose van stock covers the likely part, and sends the address, fault summary and site history to their phone.

Safety

Gas and electrical go straight to a human

Any mention of gas smell, smoke or electrical burning skips triage entirely and connects the caller to the on-call supervisor while sending an SMS alert. That path was tested weekly for the first quarter.

Result

Engineers dispatched while the caller is still on the line

Median time from call to dispatch fell 38 minutes. Full out-of-hours coverage let Brightflow sell an emergency response tier it had previously declined to offer, worth around £140,000 in its first year.
