Upon my arrival I evaluated 1 furnace 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 for the main house condenser lower than normal, found the voltage enhancement system lower than normal, I also found the surge protector. O longer active. On the mini split I found no issues. David approved an estimate to replace the surge protector. I performed the repair option, this system is now working properly
