Gas furnace question/problem
--------------------------------------------------------------------------------
my son has G.E. gas furnace in his attic. he has recently had work on his home which stirred up tons of dust, etc. and clogged the filters. as a result when they went to use the heater, it did not work and the blower motor overheated and is kaput....must be replaced. when the tech went to replace the blower he told my son the heat exchanger had cracks in it. my son and i went to look and there are exterior burn marks on the outside of the unit, appearing to be coming from underneath the furnace. my son said the heater was overheated from the blower not working to the point he could barely touch the thing when he went to see why it was not working. do we just assume the furnace has to be replaced...cost of $1500. the blower is already here ($300) and is to be installed today. our concern, naturally, is we don't want the place to catch on fire, or spit out the toxic fumes. could the burn marks just be from when the unit overheated? we really don't have a clue as to what to do. the tech initially said to replace it, and then backed off that saying it has probably been like that and is ok to use as long as it isn't running on, say, 80 degrees for long periods of time.
i would sure appreciate any expertise that could be offered as we don't know what to do. thank you very much for your time and advice.
