Responded to a service call in Langhorne, PA 19047 for a furnace water leak. Found the condensate drain from the furnace was disconnected, causing water to leak inside the unit. Also discovered the AC condensate line wasn’t plugged into the pump and an active leak at the exhaust line’s 3” elbow. Reconnected the drain, corrected the setup, and verified proper system operation. Another local home’s heating and cooling system is back to safe, efficient performance.
