It seems the real automotive, boiler and HVAC mechanics have gone my the wayside... I am looking for a recommendation for a good gas/oil boiler mechanic.

Someone who knows how to repaid a burner rather than just place a computer on it and tell you to replace parts as part of his troubleshooting process..

Added info: I currently use the service provided as part of contract with my fuel provider... new guy every time there's an issue and every one has a different opinion and no one takes the time to actually troubleshoot, diagnose and repair.. or at least see what the last 5 guys did to get a history!

If you have a good recommendation, please drop one here!

Thanks in advance
