I've got an antique 50's vintage oil burning furnace that needs to be replaced but I haven't got the money to replace it with what I want to just yet but it needs some work that is probably beyond the value of the furnace. I have a modern high efficiency burner in it but it has burned a hole in the firebox so the firebox needs to be repaired or replaced. In addition the bearings are squeaking on the squirrel cage fan so it's going to take a dive at some point but they've been noisy for years, the firebox is the safety and immediate concern.

Can anyone point me at someone who could repair an antique like this?
In the long run I want to replace the whole affair with a heat pump but that requires some remodeling to accommodate. I am in Shoreline, Washington just north of Seattle.
