Post-Uri no-heat calls across I-35E corridor
February 2021 taught Carrollton homeowners that furnace failure is not theoretical. When the temperature drops below 25 in Farmers Branch or The Colony, the phone surges between 7 and 9 PM. You are finishing a thermostat swap in Downtown Carrollton; two calls come in while you are on the ladder. The homeowner who got voicemail books a Lewisville shop with a live answer. Narlo replies via SMS within 10 seconds, asks for the address and symptom, and schedules the service call into your CRM. The Owner-operator covering Carrollton-Farmers Branch ISD area does not need a second dispatcher to capture post-freeze no-heat work; the system handles qualifying questions and booking while you finish the current job.
