I've received the bills for the two service calls, totaling $440. Here's what was done, according to the bills:
First call:
- Annual tuneup
- Nozzle
- Pump strainer
- Filter oil cartridge
Second call (2-hour labor charge):
- Checked chamber
- Cleaned out cover
- Trimmed blanket
- Replaced tank vial
- Sealed around reducer at chimney
Note that the problem reported both times was "smoke smell in house." $440 seems like a lot for an unsolved problem. My (uninformed) guess is that the problem is the smoke pipe. How much would it have cost if they only changed the smoke pipe?
