Performed Platinum Comfort Club Membership Tune-Up on Heating System Lennox furnace w/ AA413 filter on well gas. All checks good at this time. Customer pointed out small water leak spot appearing to come from filter box. Only one tiny corner spot was wet with no signs of a point of origin. However blew out all drains, trap, and tubing, ensured tight connection on coupling from inducer to exhaust and no water issue shown through rest of test operation.
