We recently moved into a new (old) house with a high efficiency furnace. There was water accumulating on the floor just beside the furnace. The Appliance Doctor, Jason came in to diagnose the problem. The levelling was off where the water flowed away from the drain instead of toward it. Since Jason levelled the unit, the leaks have stopped. Jason showed up on time, was within budget and explained how the furnace worked and what to watch out for in terms of maintenance and monitoring. Thanks Jason for your help. Now my laundry room is dry and mold free.
