During my 20 point inspection, I Started off with hosing down condenser coil of any dirt and debris. Cleaned under compressor as well. Opened condenser cabinet and checked everything thoroughly. Starter (good), fuses (good), motherboard (good), dual secondary motor control (good), 24v (good), 120v (good), refrigerant levels sh 4, sc 2, osa 81, delta 29. Then went onto the furnace and checked furnace cabinet thoroughly. Blower motor (good), single secondary motor control (good), motherboard (good), 24v (good), 120v (good). House cools great and ready for summer.
