Weymouth · No Heat
Weymouth boiler or furnace down, sooty, or setting off a CO alarm? Get outside first for gas or CO. Once everyone's safe, call and you'll be connected with an independent local heating pro.
Weymouth, Massachusetts
Weymouth's town housing plan says almost two thirds of its homes were built before 1960, and more than a quarter of households still heat with oil. That combination means many cellars hold a boiler or furnace venting into a masonry chimney that is older than the equipment itself, and some of the most serious no-heat calls are really venting problems.
So treat a carbon monoxide alarm, a smoky smell, or soot around the burner as the emergency, not the cold. If an alarm sounds or you smell gas, get everyone outdoors and call 911 or National Grid, which delivers Weymouth's natural gas, from outside the house.
Our role is referral only: call or send a request and you'll be connected with an independent heating contractor who serves Weymouth; that business inspects the system, quotes the work, and does the repair.
A thud from the burner followed by smoke or soot around the boiler means unburned oil ignited at once. Shut the system off at its switch and call; don't restart it.
Dark film on the burner door, the smoke pipe, or nearby walls points to poor combustion or a venting problem.
If people feel dizzy or sick when the heat runs and better outdoors, treat it as carbon monoxide even without an alarm, and leave.
Missing bricks, a bent cap, or a heavy snow pile around the chimney after a storm can block the flue for every appliance using it.
Local knowledge
Fuel, housing age, and fire department paperwork set the scene for a Weymouth heating emergency.
Oil Still Matters
In the Census Bureau's 2020 to 2024 estimates, about 46 percent of occupied Weymouth homes on utility gas, 27 percent on fuel oil, and 24 percent on electricity. Oil burners need regular cleaning, and one that's overdue can soot up its chimney or misfire on the first cold night.

Mid-Century Chimneys
About 16 percent of Weymouth's housing went up in the 1950s alone, according to the town's 2026 Housing Production Plan. Boilers and furnaces in those houses often vent through the original chimney, where a cracked liner, fallen brick, or blocked cap can push exhaust back indoors.

Form 1 By Email
The Weymouth Fire Department's Fire Prevention Division accepts Form 1 applications for oil burners, tank removal, and tank installation by email. If an emergency visit ends in a new burner or tank, the contractor files that form; gas work runs through the Department of Municipal Licenses and Inspections.

Right now
Safety comes first; skip any step you're not comfortable with.
Take everyone outside, pets too, and call 911 or National Grid from the yard. Don't open windows on the way out or try to find the source.
If you see soot or smoke, or heard a puffback, use the boiler's emergency switch to keep it off. Running it again can spread soot through the house.
From the ground, check whether the chimney cap or top bricks look damaged after a storm. Mention what you see when you call; don't climb onto a snowy roof.
With no warning signs, check that the thermostat is calling for heat and the oil tank gauge isn't sitting on empty before you call for service.
What to expect
For an oil or gas appliance venting into a chimney, expect a combustion check along with the repair: the technician measures how cleanly the burner fires and whether exhaust is moving up the flue. If the chimney itself is the problem, they may tell you to have a chimney professional inspect it before the system runs normally again.
If replacement is needed, Weymouth's Department of Municipal Licenses and Inspections handles gas and building permits, and its inspectors keep early-morning office hours for scheduling. Oil burner and tank work goes on the fire department's Form 1. Ask the contractor to confirm which filings they'll make.
Clear the path to the boiler and the oil tank, and note where the chimney cleanout door is if you know. A technician can work faster when they don't have to move stored items first.
Hire smart
Massachusetts has no single HVAC license. Gas work needs a gas fitter license, oil burner work a Department of Fire Services certificate, ductwork a sheet metal license, and larger refrigeration systems a refrigeration technician license. Most heating and cooling installs need a town permit.
On older chimney-vented systems, ask whether the technician tests combustion and draft as part of the visit, not only whether the burner lights.
Oil burner technicians hold a Department of Fire Services certificate; gas work requires a Massachusetts gas fitter license. Both can be checked online before you agree to the work.
After a puffback, soot cleanup is often a separate job, sometimes handled through homeowners insurance. Ask the contractor to document the damage in writing.
Costs
The cause sets the price range. A clogged oil nozzle or filter is usually a smaller job than a failed control, and either is far smaller than relining a chimney or replacing a boiler damaged by soot or a cracked section.
Ask what the visit costs before the technician comes, and get any repair beyond the diagnosis written down first. If a chimney or soot problem is involved, ask for separate written estimates so you can see what belongs to the heating work and what doesn't.

A puffback is a small ignition of built-up oil vapor inside the boiler or furnace, often with a bang and a burst of soot. Turn the system off at its switch, keep it off, and call for a technician; if anyone feels ill or a CO alarm sounds, leave and call 911.
Yes. If exhaust can't rise through the flue, it can spill back into the basement and living space. Leave the house, call 911 from outside, and have the venting checked before the heat runs again.
Yes. Weymouth Fire Prevention uses Form 1 for oil burner installation, tank removal, and tank installation, and accepts it by email. Your contractor typically files it.
National Grid delivers natural gas in Weymouth through its Boston Gas company. Leave the house first, then call 911 or National Grid from outside.
