The company visited my home for furnace maintenance on three occasions (2010-14) for water leaks. Furnace is 11 years old. The first complaint is that the company failed to do routine clean-outs each time of simple hose connections and a condensate trap. All these can be done by a homeowner btw, but we were never advised. For the latest leak, the technician quickly resolved it with a flush-out of the small plastic condensate trap. However, he then claimed there was a crack in the second stage heat exchanger, and tried to show me with his flashlight. He advised I needed a new furnace and estimated the cost. Seeking a second opinion, another contractor advised that there was no crack, and to find one in that location (or demonstrate to me), Appleby would have to remove the blower. That was never done because, Appleby warned, that was an all-day job, costing $1000, We now know that removing a few screws is all it takes. Appleby escalated the claim to Consumers Gas who are obliged to inspect and shut down the unit if faulty. CG also inspected the furnace and found no crack. The episode cost me $300. for initial and follow up visits.Maybe the company is honest, but Dan did not give good service.
