I paid $4200 for a new furnace from Weber and Grahn, but when it arrived it was already defective (Weber and Grahn sold me a furnace with a wrong part). Do not buy anything from Weber and Grahn. They could not fix it. One of their own mechanics saw it and said it could blow up. Another one of their mechanics spilled fuel from a fuel can onto my basement floor -- he left the can there and it had to be cleaned up; the fuel spill caused by him smelled upstairs as well. I had to pay $800 of my own money to get the furnace fixed (from a different company) even though the new furnace was under warranty. The company president Mr Grahn never returned my phone calls. None of the repairmen from that company ever fixed the problem. They also attached a humidifier to the furnace whose parts needed replacement the same time. Also, the company was sarcastic to me, and even screamed on the phone when I told them I could not turn the heat on because of the fumes and noise. It's a good thing I sought out another company to fix it, even though it cost a lot. The furnace was shaking and sounded scary. FUMES came into the house. It was dangerous.
