I was a highly skilled and experienced home service professional who completed a wide range of tasks for my clients. One of the jobs I performed was to add two heat runs off the bottom of the trunk line in the basement and run four inches of run to the room where the water main will be. I finished hooking up the AC lineset and electric for both units, finished wiring in the furnaces, and ran the vent and combustion. I also installed a tankless water heater.
