During my twenty point inspection, I started off with hosing down condenser coil of any dirt and debris. Opened condenser cabinet and checked everything thoroughly. Starter (good), fuses (good), fan motor amps (0.9), dual secondary motor control (good), 24v (good), 240v (good). Refrigerant there is 0 pressure, there is a significant leak into system. I saw oil residue in condenser coil. There could also be one in coil, and wasnâ€™t able to check refrigerant levels. Owner is aware of leak, will call us if they want to speak with supervisor. Then went onto the furnace and checked furnace cabinet thoroughly. Blower motor (good), single secondary motor control (good), motherboard (good), 24v (good), 120v (good).
