Upon arrival, there is visible water standing in bottom of furnace cabinet, aswell as a bit around the bottom air box on the floor. Poured water into drain system to locate leak. Found the cabinet penatration fitting leaking at the threaded connection. Disassembled and added Teflon tape to seal the threads. Poured more water through the system and no other leaks were found. Current standing water may take a day or two to dry up. During leak search, noticed that the inducer motor had an extensive amount of water damage. Femi also informed that there has been a previous failed gas valve that needed replaced, aswell as an extensive history of rusty burners and eventually had the burners replaced entirely. All of these issues are common problems with systems that do not have an intake air drain trap installed. During the summer, hot, humid air naturally moving through the vent system is able to condensate, and drip onto the internal components, he inducer motor, gas valve, and burners. I
