Checked system. 2001 two stage variable furnace and 2012 cooling equipment. Compressor not operating due to a weak 30mfd capacitor. Installed a new turbo200 and start assist kit for 4 ton. System has a low subcool. Gave homeowner repair and replace options, repair to get system back up and cooling for now but no refrigerant added. Will look and decide on which system to replace with. Left 4 line with discounts applied for oncor, trane and senior citizen.
