Well, the furnace guy has come and gone...and took $189 of our hard earned money with him. He also cheerfully informed me that we need a new furnace ASAP. I called Jed to inform him of this news, and he had been doing some internet research on this company, and apparently they are known for telling people they need more than they need. So we will be getting a second opinion before we shell out to anyone for a new furnace. Apparently this company has more BBB complaints than any other company in the area. I wish I'd known that before I called them.
I wish we could still trust people to be honest with us about things like that. It makes me sad.
