Upon my arrival in Rosanky I performed a 6 month checkup on 2 straight electric heating systems. On the upstairs system I found the return plenum still needs to be sealed and the heat transfer media coil is starting to get dirty. I found everything else operating properly in both the performance and safety aspects. On the downstairs system I found the wire going to the 15kw heat kit was not the proper size and was jumped over from the 10kw to the 5kw. I removed the wires that were jumped to the 5kw allowing the system to only operate 10kw on the electric heat. I found everything else operating properly in both the performance and safety aspects. I went over all of my findings with the customer. She would like the quote for the upstairs system emailed back over and plans to call Bobby out to install a better attic access at the upstairs system.
