What boiler maintenance & tune-up involves
A tune-up cleans the burner and heat exchanger, checks ignition and flame sensing, tests safety controls and measures combustion with an analyzer for efficiency and carbon monoxide.
Oil boilers usually get a new nozzle and filter. Condensing boilers need their condensate trap and neutralizer checked.
Water-side checks include pressure, relief valve, expansion tank and, on steam, the low-water cutoff and water quality.

Boiler tune-up in Medford: local context
Medford's housing stock is old by national standards. Many homes and two-families were built before the Second World War, and triple-deckers and Victorians across the city were designed around steam or hot-water boilers with cast-iron radiators.
A lot of those systems have been converted or replaced over the years: oil to gas, steam to hot water, old cast iron to compact high-efficiency condensing boilers. That mix means the right technician needs to understand both old piping and new controls.

Have this ready when you call
