Service call no heat . When I arrived to the home and was doing my initial inspection I smelled gas . Located gas leak on gas line entering furnace . The furnace had power but was not actuating. The condensate pump was full and had failed cutting off 24 volts to furnace . Replaced necessary gas fittings and replaced pump . Tested work no gas leaks were present and new pump performed well. The furnace is operational and working at this time.
