Setpoint Services completed commercial HVAC and refrigeration repairs at Domino's Pizza Elgin, located at 910 Lee Dildy Blvd, Elgin, TX 78621. The visit included repairs to a Trane rooftop air conditioning unit, preventative maintenance on a Daikin rooftop unit, and refrigerant service for the restaurant's walk-in cooler.
The rear Trane rooftop unit was originally found with restricted condenser airflow and a failed indoor blower motor caused by an improperly secured run capacitor installed by a previous service company. During the return visit, Setpoint Services installed a new 460-volt, 1/2 HP condenser fan motor and a new 10 MFD run capacitor, rewired the motor to verify proper rotation, and tested the system after repairs. Final operating conditions measured 135 PSI suction pressure, 420 PSI discharge pressure, and an 18°F temperature split between return and supply air, confirming normal cooling performance. The front-of-house Daikin rooftop unit was also verified after condenser cleaning and produced a 17°F temperature split, confirming satisfactory operation. Although both rooftop units were operating properly at the time of departure, the Trane evaporator coil remains heavily soiled and should be professionally cleaned to improve airflow, efficiency, and long-term system reliability.
Setpoint Services also restored operation of the walk-in cooler by adding 5 pounds of R-404A refrigerant to bring the refrigeration system back to its proper operating charge. After charging, the walk-in cooler successfully pulled down to the customer's 35°F setpoint. Although the liquid line sight glass continued to flash slightly, the cooler maintained proper box temperature, and the customer elected not to add additional refrigerant at that time. Both the commercial HVAC equipment and walk-in cooler were operating normally upon completion of the service visit.
