Arrived for blue club AC tune-up. Checked blower motor capacitor and blower motor amp draw which are both in range. Compressor amp draw and fan motor amp draws are in range as well. Low ambient temperatures made getting exact refrigerant pressures difficult but they do look good. Condenser was washed. Main recommendation is doing a pan treatment every year due to the soot buildup to help prevent any clogged drain lines. Also recommend a surge protector to help protect the unit from surges. Overall the unit is functioning properly and the condenser and filters are clean and ready to go for summer
