Completed full service tune-up and safety check. Found no issues with any components or the refrigerant charge. Unit was cleaned with disassembly. Unit had a completely lugged outdoor coil. This system to the best of my knowledge is good to go for this summer. Customer has been notified that the unit is past the typical life expectancy and that the unit doesn’t compare to todays units as far as efficiency goes. Customer was informed that if unit should need anything other than a small repair that it would be the time to replace it.
