How a Knox County territory works
When a homeowner in one of the ZIP codes above dials 844-JOB-HVAC (844-562-4822), the call is answered by an AI agent that qualifies the job, asks the homeowner to text a photo of the unit, and generates a damage estimate from that photo. You then receive one SMS containing the homeowner's name, phone number, address, problem description, the photo, and the estimate — before you call back. Nothing about that lead is sold to another contractor.
A contractor may hold up to 3 ZIP codes. Read the full mechanism on how it works, or compare the economics against shared-lead platforms in exclusive vs shared HVAC leads.
