Fagnan's Furnace Services

8 yr old Carrier furnace wasn't starting up in morning. Called for service call. Tec came & couldn't figure out why it didn't start up when thermostat called for it to start. Was charged for service call even though I had purchased at my extra cost a total 10 yr parts & labor warranty package when I purchased the furnace. Furnace still not cutting in so I called again & another service tec came out. Diagnosed that it was the hyme damper circuit being faulty so cut that out & furnace started. I then asked him to check the heat exchanger. I only was aware of this after talking to other service tecs installing a furnace up the street & them telling me my furnace model had heat exchanger problems. He checked PPM on heat exchanger & it was way over limit so needed heat exchanger replaced. They replaced it the next day which was great but I was very shocked that I ended up with an approx. $600 bill, even though I had full parts & labor warranty package which I paid extra for when I bought the furnace from them. After several inquires they came up with a list of items to try and justify their extra charge (most items didn't make any sense to me that they should be an extra charge) above my parts & labor warranty package I had already paid for. NOT happy with the extra unexpected bill as I was sure I should be totally covered on repairs with my extra parts & labor warranty I had purchased. It seemed like I was paying twice! Not fair!
