the unhappy homeowner

this morning we woke up to the furnace broken and the house was 45 degrees!
First we thought we were out of propane. So, I called them to fill the tank, but the tank had 20% fuel still in it...
Second, we called the furnace people and they came right away.
The furnace guy said "Looks like it just needs to be cleaned out, lots of soot accumulating." yadda yadda yadda. So, he did just that to a tune of $160.
Turns out, that didnt fix the problem, the unit still gets too hot and trips itself out.
It needs a whole new part, I forget what part it was but he says "We have to order that part." they're next day-airing it.
This is fun, especially when daytime temps are -10 degrees!!!
OH, yeah, it ups the price to $600.
