Upon my arrival I evaluated 2 furnace strait cool systems. 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 voltage enhancement system low for the left indoor furnace, both heat exchangers need a cleaning, I also recommended replacing both voltage distribution systems and voltage enhancement systems on both out door units. . Trevor approved the complete voltage enhancement system renovation for both outdoor units, which allowed me to replace the voltage distribution systems, voltage enhancement systems, install hard start kits clean coils for both outdoor units.
