There is a furnance union. In their contract they are required to quit functioning at the most inconvenient time.
The first house I owned...the furnace went out during a below-zero-cold- snap. I don't remember what the problem was but I do remember it was a crack in something that made it dangerous to use. So I keep the heat below 60 until I could get a new one installed. I do not remember what I paid.
The next time I had furnace problems (two houses and one marriage later) it was on Christmas Eve when all my family were staying with us. At least there were plenty of people to huddle together and share body heat :rolleyes: :rolleyes: ;) . The repairman came as we were sitting down to eat. I remember we invited him to join us.
Sorry I don't remember prices. My mind tends to shut out details of painful situations.... :D ;) :D
