What matters for boiler tune-up in Medford
Steam boiler checks
Steam systems need the water level, sight glass and low-water cutoff checked, and oily water skimmed if the boiler surges.
Combustion testing
A combustion analyzer confirms the boiler is burning cleanly and checks carbon monoxide in the flue.
Book before the rush
Late summer and early fall are the easiest times to schedule before the first cold snap.
