Arrived at customers house to perform routine tuneup. Checked all electrical components and they were operating within manufacture specifications. Checked refrigerant levels which appeared low. The outdoor coil was very dirty so I performed an ECC and also re-leveled the unit. After cleaning the outdoor coil, I rechecked the refrigerant levels And they were well within the proper settings. Checked static, which was a bit high however, supervisors will be scheduled to make a visit. Thank you for choosing LBA!
