I-30 corridor response math during DFW heat surges
A single truck covering Grand Prairie, Arlington, and Duncanville faces 18–26 minute drive windows during the first three 100°F days of summer. If you miss a no-cool call from South Grand Prairie at 6:45pm and call back at 7:20pm, the homeowner already booked the Irving shop that answered in three minutes. Narlo replies in 10 seconds via SMS, sounds like your dispatcher, and gets the address and system details while you finish the Mansfield install. By the time you walk to the truck, the Lake Ridge appointment is in your CRM with a booked time slot. You route Cedar Hill before Arlington, or you take the Highway 161 job first and push the I-30 callback to morning—the customer already agreed to the window. Every August heatwave call that goes to voicemail is a $400 margin decision, and the I-30 corridor does not wait.
