Types Of Boiler Faults
No heat or only some rooms heat. Air trapped in a loop, a stuck zone valve, or a weak circulator can starve part of the house. We purge air, prove flow, and confirm each zone responds.
Pressure swings and relief discharge. A waterlogged expansion tank or a failing fill valve lets pressure climb. We set the tank pre-charge, dial in the cold fill, and verify the relief stays dry during a full cycle.
Leaks and corrosion. This could be drips at pump flanges, unions, or the relief line point to gasket wear or component failure. We isolate the source, replace parts, and check that water did not reach controls.
Kettling, banging, or gurgling. Scale on heat-exchange surfaces and low flow create noise and hot spots. We restore circulation, clean strainers, and address water quality so the boiler runs quietly.
Lockouts on modern units. Condensing boilers fault on flame signal, condensate blockage, vent issues, or sensor drift. We pull the code history, clear blockages, and confirm stable combustion before putting the unit back in service.

Units We Repair
Gas hot-water boilers. Atmospheric and sealed-combustion models. We verify ignition, safeties, and circulator performance against nameplate targets.
High-efficiency condensing and combi units. We clean traps, confirm vent terminations and slope, check sensors, and set combustion within manufacturer ranges.
Oil-fired boilers. We service burners, nozzles, electrodes, and cad cells, then set draft and combustion for steady, clean heat.
Older steam systems. We correct low-water cutoff issues, skim oils, set pressure controls, and level radiators for even distribution.

How Boiler Repair Works (Boiler Repair in Hopedale, MA)
Arrival and safety. We secure power and fuel, check for leaks, and confirm venting. Carbon monoxide risks and low-water protection come first.
Step-by-step evaluation. We call for heat and watch the sequence: control response, ignition, flame verification, circulator start, and zone operation. Hydronic readings go on our checklist so choices are driven by numbers.
Repair and verification. After approval, we install parts, purge air, set tank pre-charge, and stabilize pressure through a full heat cycle. On condensing models we flush the trap, clear error history, and verify supply and return temperatures for each active zone.
Handoff. You get the fault found, the work performed, and simple tips that keep filters clear on air handlers and water quality in range.

Preventative Maintenance
Protect pressure and flow. Watch the gauge. Frequent changes point to a tank or fill issue. Clean strainers and confirm the auto-fill valve closes fully.
Mind water quality. Minerals and oxygen drive noise and corrosion. We test and treat when suitable, then recommend steps that match your piping and boiler type.
Tune before the first deep cold. Cleaning sensors, checking ignition, confirming pump amps, and purging air prevents most lockouts on the season’s first freeze.

FAQs
Air in loops, weak circulators, stuck zone valves, fouled flame sensors, clogged condensate traps, and waterlogged expansion tanks are typical. We test the sequence so the repair addresses the cause, not only the symptom. For targeted troubleshooting, call (508) 310-0955.
Hot-water systems should be closed and dry. Leaks at the relief valve point to pressure problems or an expansion tank fault. Drips at pumps or unions suggest gasket wear. We correct the cause and set the system to the proper cold fill. See water on the floor? Call (508) 310-0955 for a quick check.
Call if you smell gas, hear kettling or banging, see frequent pressure trips, or the boiler locks out. No heat during freezing weather also warrants a visit. For earliest availability, call (508) 310-0955.
Power cycling can clear a one-off lockout, but repeated resets point to a real fault. Do not bypass safeties. If it trips again, stop and schedule service so we can find the root cause. Need guidance before you try a reset? Call (508) 310-0955.
