"Furnace wasn’t working on Friday morning after thanksgiving. Called Hartman Brothers. They were able to get here in the early afternoon. They diagnosed the problem and got it fixed quickly. Communication was excellent. Price was more than I expected, but understand that parts for 20+ year old furnace are not inexpensive."
