I-2 corridor dispatch during RGV heat surges
A shop running three trucks across Pharr, McAllen, and Edinburg cannot let a no-cool call sit for six minutes while the dispatcher is routing a parts pickup near the Pharr-Reynosa International Bridge. That caller has already opened the next Google result. Expressway 83 runs straight through the Rio Grande Valley, but your service-area math breaks down when the lead tech is in Alamo and the emergency is in North Pharr—unless someone locks that job in immediately. Narlo replies in 10 seconds, qualifies the address and system type, and books the call into your CRM before the homeowner scrolls past your listing. The subtropical load in Hidalgo County means compressors fail without warning; the first shop to confirm arrival time wins the dispatch.
