Sam Rayburn Tollway radius kills callback windows
A two-truck electrical shop running Frisco, Plano, and McKinney covers 180 square miles when you count the Sam Rayburn Tollway to Preston Road corridor. A breaker-trip call from Lone Star Ranch at 9am competes with a panel-arc emergency in The Colony by 10am. You miss the first call because you are wiring a generator at The Star, and the homeowner books the shop that texts back during your drive. Narlo replies in 10 seconds from the job site, qualifies whether the breaker is hot or just nuisance-tripping, and books the appointment into your CRM while you finish torquing lugs. The callback window on Dallas North Tollway corridor calls is 8 minutes; Narlo closes it at 10 seconds.
