Upon arrival I began the AC tune up. I started downstairs at the furnace to check the running amps on the blower motor which was within specifications. Next, i replaced the filter from an Aprilaire#213 to a 20x25x4 inch Merv 8 box filter. All the electrical components are testing within specs. The outdoor unit was clean when i arrived today. The refrigerant charge looks very good and is testing within the manufacturer specifications. Your system is ready for this summer.
