Upon my arrival I evaluated 1 furnace split system. I verified system safety and performance is to manufacture specifications. Flushed and treated the water removal system. Cleaned the electrical cabinet and washed unit using water. Found the pressures lower than normal, I also found the voltage enhancement system lower than normal and I also found the start capacitor lower than normal. I was approved to add r410a and I only needed to add 4LB’s . Mike chose to wait before replacing the voltage enhancement system and the hard start kit.
