Replaced a Make-Up Air Blower Belt at a Sonic Restaurant 06.25.26

A Robinson TX Sonic reported its make-up air unit had stopped pulling fresh air into the kitchen, throwing the building's pressure balance off during service hours. Clay inspected the rooftop MUA and traced the fault to a worn blower belt that had lost tension and slipped off true. He installed a new belt, set correct tension, and left a spare on-site so the kitchen crew can avoid a future emergency call. The unit returned to full airflow the same day with no added downtime. While on the roof, Clay also noted a couple of additional maintenance items for the operator to schedule. Need commercial HVAC or make-up air service in the Waco area? Call 254-272-2714.
