Have a 1998 Lennox oil fired boiler that has given me fits for the last two years. May be related to an old oil tank and filter. Just replaced the oil tank and filter system with all new.
Last 2 years have had to "deep clean" both combustion chambers at considerable cost. Is it possible that the contaminated fuel (sludge, rust, and water) caused the rapid soot build up each year? CO levels have been normal. They have been measured with a calibrated CO detection tool.
Any one know of websites that might give a breakdown on how to "deep clean" a Lennox furnace and how to set the ignitors? Cannot be that difficult for a mechanically inclined person to follow some directions to save $400.00 or more that is charged for this service locally.

a cleaning is a cleaning. The heat exchanger should be cleaned and the burner should be tuned. here in Maine it costs around $125.00. Did you use the same company? Did they do a smoke test? After tuning you adjust the air so there is no smoke, then you do a co2 test. Some hot shots think they can adjust the flame by sight, but they are sadly mistaken.

I will agree you are paying too much but not that a cleaning is a cleaning. The same things have to be done, it's a matter of difficulty.
A proper combustion analysis should consist of: Smoke, draft, CO2 (or O2), CO, & stack temperature.
Yes, it is possible the contaminated fuel caused the sooting. Another common problem is the lack of combustion air. If the basement is tight, you can burn up oxygen faster than it comes in. This may not evidence itself during the brief run for combustion testing but once the boiler runs for heating, it could easily be a problem.
