I-820 service-area math during DFW heat surges
A shop running two trucks out of the Fairmount area can cover Westover Hills to Saginaw in 40 minutes during normal traffic. When the heat dome hits and you field six no-cool calls between 5pm and 8pm across Fort Worth, the math breaks: truck one is in Aledo replacing a capacitor, truck two is stuck on I-35W southbound near the Stockyards with a compressor swap, and the homeowner in Tanglewood who called at 6:20pm gets voicemail. She books the shop that texts back in 90 seconds. Narlo replies to the Tanglewood call while your trucks finish Aledo and the Stockyards, qualifies whether it is a capacitor or a full coil job, and slots the booking into your Thursday route before the homeowner opens Google again.
