Preventative maintenance technician returned to complete the comprehensive spring PM at a hardware chain store in San Francisco, CA. Filter change and coil cleaning had been completed on previous visit. The tech changed belts on all Lennox package units and recorded multiple minor issues. Deficiencies were quoted to the customer to approve.
