I've been having problems for about a year with my oil burning furnace. The furnace is only 5 years old. Starting last year I was having to continually push the reset button to get it to fire. Then it went to not working at all. I have had the repairmen out about 10 times over the past 12 months and they finally replaced a part (forgive me I don't remember what) so that now it runs and heats. However there is a lot of soot and it's quite loud. I had the repairman out again today and after running several test he determined that the problem is a "dead" chimney and not a cracked heat exchanger.
He admitted he's only seen this problem about 3 times over the past 12 years so I'm a bit skeptical. I don't want to have to pay $1200 for a new chimney liner if it's not really going to solve the problem. Does anyone have any words of wisdom?
