FM 1171 service radius math kills August callbacks
A Flower Mound HVAC shop running two trucks covers FM 1171 from Highland Village west to Old Flower Mound, with Highway 121 calls stacked from Tour 18 down to Grapevine. When the first 102° day hits in late May or the August heat dome settles over Denton County, dispatch juggles twelve open service tickets and a ringing phone. You miss a no-cool call from Lakeside DFW at 11am because both techs are elbow-deep in capacitor swaps near Stone Creek. The homeowner hangs up, dials the next shop on Google, and books a same-day slot fifteen minutes later. You call back at 1pm when the tech clears; the lead is gone. Narlo catches that inbound within ten seconds, texts back as your shop, qualifies the address and symptom, and drops the booking into your CRM before the homeowner scrolls to the next result. Every FM 1171 corridor call lands, even when you're routing trucks across Lewisville or Coppell.
