August heat-dome surge across Collin County kills callback time
The August 2023 heat dome sent Oncor demand records and every HVAC line in Allen into overflow. A no-cool call from Cottonwood Bend at 7pm competes with three more from McKinney and Frisco before you clear the Stacy Crossing job. By the time you call back at 8:15, the homeowner booked someone who replied at 7:03. Narlo sends the first SMS reply in 10 seconds, qualifies the urgency and system age, and holds the lead while you finish the current ticket. The customer sees a response that sounds like your dispatcher, not a chatbot, and the booking lands in Jobber with address, callback number, and whether they have a maintenance plan.
