Lexington has a wide range of heating systems. Older colonials and Victorians near Lexington Center often still run cast iron boilers feeding radiators, many of them steam. Mid-century homes commonly have hot-water baseboard systems that have been through two or three boilers already, and newer homes may have high-efficiency wall-hung condensing boilers with indirect water heaters. Each type fails in different ways, and the right repair depends on which one is in the basement.
Common Boiler Problems We Fix in Lexington
- No heat or no hot water: ignition and flame-sensing failures, failed circulator pumps, zone valves stuck closed, and tripped limit controls
- Some rooms cold: air in hot-water zones, failed zone valves or thermostats, and unbalanced or clogged piping
- Banging or knocking pipes: water hammer in steam systems from improper pitch or a flooded system, and kettling from scale in hot-water boilers
- Pressure problems: a waterlogged expansion tank, failing fill valve, or relief valve discharging
- Leaks: at circulators, valves, near-boiler piping, or a cracked section, which usually means replacement
- Oil burner faults: nozzle, filter, electrode, and fuel pump problems on oil-fired equipment
Repair or Replace?
Damaso Plumbing & Heating Inc inspects before recommending. A failed circulator, zone valve, igniter, or expansion tank is usually a repair. A cracked heat exchanger, a boiler leaking from its sections, or repeated major failures on a system 20 to 25 years old or more usually points to replacement. When replacement makes sense, the company sizes the new boiler to the home’s actual heat loss rather than matching the old unit’s rating. Older Lexington boilers are often oversized, so a correctly sized boiler can run more efficiently. Massachusetts homeowners replacing heating equipment should also check current Mass Save rebate programs before choosing equipment.

Frequently Asked Questions
How often should a boiler be serviced?
Once a year, ideally before the heating season. Oil-fired boilers need annual cleaning and a nozzle and filter change to run efficiently. Gas boilers need combustion, venting, and safety-control checks.
How long does a boiler last?
Cast iron boilers commonly last 20 to 30 years or more with maintenance. High-efficiency condensing boilers typically last around 15 to 20 years and need regular cleaning of the heat exchanger and condensate system.
Can you work on steam heat in an older Lexington home?
Yes. Damaso Plumbing & Heating Inc repairs and services steam boilers, including water level controls, low-water cutoffs, pressure controls, and near-boiler piping, and can replace steam boilers when needed.
What should I do if my boiler stops working in winter?
Check the thermostat, the boiler’s emergency switch, and the breaker first. If there’s still no heat, call. See emergency plumbing and heating for steps to protect pipes from freezing while you wait.
