You lose no-cool calls during DFW heat surges
August 2023 heat dome taught every Richardson HVAC owner the same lesson: the first 100°F day floods your phone, and the second call to a busy line goes to the next shop on Google. A homeowner in CityLine with a failed capacitor does not wait; the apartment complex in Canyon Creek does not leave a voicemail. Oncor's grid stays up, but your callback rate does not. Narlo answers the SMS inquiry in 10 seconds while your lead installer is finishing the coil swap in Heights Park. The reply asks unit age, thermostat behavior, and preferred arrival window — then books the emergency slot into your CRM before the homeowner opens the next browser tab. You own the surge call, or the surge calls the shop that picks up first.
