Tech Cody arrived to customer's home and met the homeowner. System is a 6yo trane heat pump. INDOOR: Temperature split was 19 degrees, the filter was clean, the drain line was clear, the static pressures were acceptable, the coil was clean, the blower was clean and the UV bulb is in need of replacement. OUTDOOR: I washed and waxed the unit, the compressor and fan motor were operating within manufacturer range, the auxiliary motor starter was within tolerance and the primary electrical control was in good condition. The refrigerant levels were at acceptable levels at this time. I shared my findings with the homeowner and recommended she replace the UV bulb, she could not at this time but intends to in the future. She requested I send the estimates to her email. System was cooling when I left.
