Came out for a local call. Upon arrival, discovered that one of the furnaces on the high voltage side was not wired in at all. They are wire nut together and need to be wired in properly and safely. New romex needed from junction box to furnace itself. All low voltage needs to be rewired and secured properly. Both systems have bad door switches and furnace boards. These parts are going to need to be replaced before any other troubleshooting can be complete. Scheduled install supervisor to come out and give estimates. Do not recommend repairs due to aids of system and the fact that we are looking at a high price just to get these units started up. House is kind of a duplex style one thermostat two systems, one supply trunk line one return trunk line. The system can be replaced with just one 5 ton system on the house as well. Recommended to convert over to one system to eliminate having to maintain two systems versus one. Left systems off at the switches as they were up upon arrival
