A restaurant in Ontario, California, was scheduled for approved repairs today. Their cook line cooler was no holding temperature. Upon arrival our refrigeration technician found the blower fan vibrating badly with a wheel that had come apart and damaged the rest of the assembly. Will quote for necessary repairs.

Approved air conditioning repairs scheduled for a loan shop in Ontario CA. Their Rheem unit had a failed blower motor that our technician replaced. After installing the motor the tech cycled the system, confirmed space temperatures dropping back to comfortable levels. Job complete.

A business in Ontario California reported that their AC was down, and they had no cooling throughout the building. Upon arrival, our commercial HVAC tech inspected their 3ton Rheem unit and found the blower motor burnt out due to severely restricted airflow. The technician cleaned the return grill to improve the flow, will need to quote and source the blower motor to get space up and running again.
