Anyone know if these are decent enough for a HO to give his modcon a check after annual burner an HX cleanings? seems like less than the cost to have someone come and I have just done my first tear down and cleaning even with the retarded fastener locations wasn't hard to clean up.Im in HVAC airside so comfortable enough to do this but if i were average owner and found out my "high efficiency boiler" needed $600 a year checkups id be pissed.
