My husband said that we had tho furnace for 15 years. He believe it time for a furnace. Do you know any used furance in Southfield Michigan?
Expert:  HVAC Guru replied 1 year ago.

Well used furnaces are really hard to come by as either they are junk or bad. Get a Goodman unit the furnace itself is pretty cheap you can get one for $1000-1200 for the unit plus an install. I doubt you will find a good used furnace, now for the issue have him take out the flame sensor and clean it off the rod really good with some sandpaper and try it...that may do the trick for the time being.
