No heat in a Woburn colonial on the coldest night, an oil burner locked out with the tank gauge reading low, water under the boiler — these are the calls that jump the queue. Emergency triage is answered 24/7.

Not every fault is an emergency. These are.
Woburn's emergency list starts at the tank: no heat with the gauge reading low is a delivery emergency wearing a repair costume. Beyond that: no heat with freezing weather inbound — colonials and splits freeze pipes in exterior walls fast; a burner that won't stay lit after one reset — repeated lockouts mean a safety is engaged, and overriding it turns small problems into dangerous ones; and active water leaks or a constantly discharging relief valve — water and old electrical controls don't mix, and water loss leads to dry-fire.
Not boiler calls: a sounding CO alarm (leave, call 911) and the smell of gas (utility emergency line or 911 from outside first). After either is cleared, the boiler gets inspected before it restarts.
The city's signature emergency.
Delivery routes stretch in long cold snaps, gauges get misread — especially older float gauges — and a burner that ran dry doesn't just need a fill. It needs bleeding and a proper restart sequence , because air in the fuel line will lock it out again the moment it tries to fire.
If your gauge reads low and serious cold is coming, call before it reads empty. An empty tank also stirs up every bit of sludge on the tank bottom, which is how a run-out becomes a clogged filter and a second visit. The cheapest emergency is the one scheduled as a delivery.
Five minutes of checks that speed up the fix.
In Woburn, the first emergency question is almost always about fuel. A burner that ran dry needs a delivery plus a proper bleed-and-restart — air in the fuel line will lock it out again otherwise, and run-outs stir tank sludge that loads the filter.
Then the universal checks: thermostat set to heat and above room temperature; pressure gauge reading 12–15 psi cold on hot-water systems (near zero means water loss; pegged high with the relief valve dripping means a failed expansion tank); and any error code or new noise — a lockout code, a bang on startup, new gurgling. One reset to rule out a fluke is fine; repeated resets flood the chamber with unburned fuel.
What happens when you call.
If it turns out to be diagnosable rather than urgent — a balance issue, a maintenance question — you'll be pointed to boiler repair in Woburn instead. The triage call costs nothing either way.
Straight answers before you call.
Check the thermostat, the red emergency switch, and the breaker — then call (888) 766-1474 immediately. No-heat calls with freeze risk go first, 24/7. Do not keep resetting a locked-out burner; tell triage whether you are on oil or gas and what the burner is doing.
No heat in freezing weather, active water leaking from the boiler, any gas or strong oil odor, or a burner that will not stay running. A new noise or uneven heat with the system still heating can usually wait for a scheduled visit. When unsure, describe the symptom — triage sorts it in a minute or two.
Call the 24/7 line and say both things — the low tank and the dead burner. Runouts pull air and sludge into the fuel line, so the restart needs a professional prime and bleed after delivery. Do not keep hitting reset while you wait for oil; describe what the burner is doing instead.
If water is reaching the burner or electrical controls, yes — shut the boiler down and call the 24/7 line. Low ground near the pond floods first, and water plus a boiler is a bad combination. Note whether the water is coming from the boiler itself or from outside; it changes the response.
A strong or growing oil odor means a leak — a weeping fitting, a failing tank seam, or a drip at the filter — and it deserves a prompt visit. Many Woburn Center tanks are decades old. Check for wet spots under the tank if you can do it safely, and mention the odor's strength on the call.
