What a Maryland territory includes

Every homeowner who dials 844-JOB-HVAC from one of these ZIP codes reaches an AI agent that qualifies the job, requests a photo of the unit by text, and generates a damage estimate from it. The contractor holding that ZIP receives a single SMS with the homeowner's name, phone, address, problem description, photo and estimate. The lead is not resold, and there is no charge per lead.
