Canton · No Heat
Heat gone in your Canton home on a freezing night? Check safety first, clear what you safely can, then get connected with an independent HVAC contractor who serves Canton.
Canton, Massachusetts
Before you reset anything, look at the carbon monoxide alarm. Canton Fire's inspection rules place one at the bottom of the basement stairs, a few steps from where a basement furnace or boiler usually sits. If it is sounding, or if you smell gas, get everyone out of the house and call 911 or Eversource Gas from the driveway or a neighbor's place. Nothing else on this page matters until that call is made.
If the alarm is quiet and the house is simply getting cold, the cause is often something you can spot: a thermostat with dead batteries, a tripped service switch, or a vent pipe buried by the last snowfall. Norfolk County, which includes Canton, has been in at least four FEMA-declared winter storm disasters since 2015, so drifted-over vents are a real pattern here, not a rare one.
When you call or send a request, South Shore HVAC Finder connects you with an independent heating contractor who works in Canton. We're the introduction, not the repair company, and you choose whether to hire the person you speak with.
A full alarm means leave now. A chirp usually signals a low battery or an aging unit, but swap the battery right away rather than letting it ride on a cold night with the burner running.
If the rooms keep cooling for an hour after you raise the thermostat, the burner isn't firing or heat isn't moving. Pipes along outside walls are at risk once the house drops well below normal.
Repeated clicking followed by silence and a red light on the control usually means a safety lockout. That's the equipment protecting itself, and it calls for a technician, not more resets.
Black streaks around an oil burner or a sharp burning odor point to a combustion or venting problem. Shut the system off at the thermostat, keep away, and call for help.
Local knowledge
Storm history, alarm rules, and the town's gas utility all bear on a Canton heating emergency.
CO Alarm Location
The department's smoke and CO inspection rules also call for more than one detector on any level larger than 1,200 square feet. With a basement furnace or boiler, that placement means the alarm hears a venting failure early, so keep it powered and tested.

Winter Storm Record
FEMA declared major disasters covering Norfolk County for the January 2015 blizzard, two March 2018 storms, and a January 2022 snowstorm. Each one is the kind of event that buries sidewall vents and outdoor heat pump units, which can shut a heating system down.

Gas Emergencies
Canton's gas mains belong to Eversource Gas. A rotten-egg smell near the furnace or boiler is a reason to leave the home and call the utility or 911 from outside, never a reason to go looking for the leak.

Right now
Work through these in order, and stop at the first one that applies.
For a gas smell or a sounding CO alarm, leave the house with everyone, pets included, and call 911 or Eversource Gas once you're outside. Leave lights, switches, and phones alone until you're out the door.
If it has snowed, check where the furnace or boiler pipes leave the house. Brush snow clear of the openings by hand from outside, and don't touch the pipes if they're hot.
Make sure the thermostat is set to heat with fresh batteries, and that the switch near the basement stairs or on the unit is on. Many heating systems have one that looks like a light switch.
Open cabinet doors under sinks on outside walls. If you use a space heater, plug it straight into a wall outlet, keep it three feet from anything that can burn, and never run a grill or generator indoors.
What to expect
A technician will usually start at the equipment: reading any error code, checking ignition and flame, and testing the safety switches. On an oil system that means the burner, nozzle, and filter; on gas, the igniter, flame sensor, and venting. Expect questions about when it stopped and whether the vents were snowed in.
If the fix is a part swap, many trucks carry common ones, but a failed control board or a cracked heat exchanger can mean waiting on an order. A replacement in Canton needs a permit: gas appliances go through the Gas and Plumbing Inspector at the Building Department in Memorial Hall, and oil burners use a Canton Fire Department permit form. An emergency doesn't waive that, so ask how the contractor will file it.
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.
Gas work calls for a Massachusetts gas fitter license, which you can check on the state's occupational license lookup. Oil burner work calls for a Department of Fire Services certificate, searchable on the DFS verification site.
Find out how the contractor charges to come out at night or on a weekend and whether that charge is applied to a repair. Get the answer before the truck rolls.
If the technician suggests a new system, ask for a written quote with the model, permits, and removal, and ask whether a temporary repair can carry you until you've compared bids.
Costs
Timing and parts are the two big factors. A visit late at night or during a storm, when every heating contractor in town is busy, usually costs more than a scheduled call, and a part that has to be ordered adds a second trip.
The fuel and age of the system matter too. An older oil burner may need a tune-up on top of the failed part, and a gas unit that has to be replaced brings permit and venting work. Ask for the cost in writing before work starts, and if a full replacement comes up, ask whether Mass Save offers through Eversource could change the math.

Questions
Still not sure? Send a short request and a local pro can answer the specifics.
No. Treat any CO alarm as real: leave the house, call 911 from outside, and wait for responders to clear the home. Have a heating contractor inspect the furnace or boiler and its venting before you use it again.
Yes. High-efficiency furnaces and boilers often vent through a sidewall pipe, and a drift over it can trip a safety switch. Clear the openings by hand after storms, and call a technician if the system won't restart.
Leave the house first, then call 911 or Eversource Gas, which serves Canton, from outside. Don't try to find the leak or shut off appliance valves yourself.
Yes. Gas work is permitted through the Building Department's Gas and Plumbing Inspector, and oil burner work uses a Canton Fire Department form. Your contractor should file the permit and set up the inspection.
That depends on the contractor's workload and the weather. When you call, you'll be connected with an independent technician who serves Canton and can tell you their timing directly.
