Milton · No Heat
No heat in Milton tonight? First work out whether it's a gas, oil, or power problem, keep everyone safe, then call or send a request to reach an independent local heating contractor.
Milton, Massachusetts
In Milton, the first useful question on a cold night is what fuel your heat runs on. Census estimates show about two thirds of occupied homes burn National Grid gas, a little over a fifth burn fuel oil, and under a tenth heat with electricity from Eversource. Each fuel fails in its own way, and each points you to a different first call.
A gas smell or a sounding CO alarm comes before everything else on this page: get people out, then call 911 or National Grid from outside. If the house is simply cold, a few safe checks can tell you whether you need a contractor tonight or whether a tripped switch is the whole story.
When you need help, call or send a request and you'll be put in touch with an independent heating contractor who works in Milton. South Shore HVAC Finder is a referral service and doesn't send its own technicians.
One reset that doesn't hold, or a burner that fires and quits again, points to a fuel, ignition, or flame-sensing fault. Repeated resets can flood the chamber with oil, so stop after one try.
Black streaks around the burner door or flue pipe, or an oily or exhaust odor in the basement, can mean poor combustion or a venting problem. Leave the system off and keep CO alarms running.
In an older Milton house with radiators along outside walls, a long outage in a deep cold snap can put water pipes at risk. That raises the urgency even if nothing smells wrong.
A puddle under a boiler, a dripping relief valve, or groundwater creeping across the floor toward the furnace all need a professional look before the system runs again.
Local knowledge
Your fuel, your utility, and your basement all change what an urgent heating repair looks like here.
Oil Still Common
With roughly one occupied home in five on fuel oil or kerosene, a run-dry tank, a clogged filter, or a burner in lockout is a familiar winter call in Milton. Tell the contractor when the tank was last filled and whether the burner has been reset.

Urgent Tank Work
If an emergency turns into replacing a leaking oil tank or burner, Milton requires a Fire Department permit on form FP-056, filed at Fire Department Administration on Engine Road. Ask the contractor to pull it rather than skipping it to save time.

Who Supplies What
Milton's gas comes from National Grid's Boston Gas and its electricity from Eversource. A gas odor is National Grid's emergency; a neighborhood outage that stops your boiler's controls and pump is Eversource's to restore.

Wet Basements
Milton's 2021 hazard plan expects more basement flooding from high seasonal groundwater. Water that reaches a burner, blower motor, or control board can stop the system, and it should be inspected before anyone restarts it.
Right now
Work through these in order, starting with the one that keeps people safe.
Don't flip switches or try to find the source. Bring everyone outside, call 911 or National Grid from the yard or a neighbor's house, and wait for the all-clear before going back in.
Gas and oil systems both need electricity for controls, igniters, and pumps. If the lights are out on your street, the outage is Eversource's to fix, and the heating system may restart on its own when power returns.
Confirm the thermostat is set to heat with fresh batteries, the emergency switch at the basement stairs is on, and no breaker has tripped. On oil, look at the tank gauge.
Close off unused rooms, open cabinet doors on outside walls, and use only space heaters made for indoor use, kept clear of bedding and curtains. Never heat the house with a stove or grill.
What to expect
Expect the technician to start by asking about your fuel and what happened just before the heat stopped. On an oil system they'll typically check fuel delivery, the filter and nozzle, ignition, and the flame sensor. On gas, they look at the igniter, flame sensing, venting, and pressure switches, and on any boiler the water pressure and circulator.
Many fixes are a part swap. If the boiler, furnace, or oil tank has to be replaced, though, permits come into play: Inspectional Services at 525 Canton Avenue covers gas, sheet metal, and electrical work, and the Fire Department covers oil burners and tanks. An emergency doesn't remove those requirements.
Older Milton houses can mean tight basement stairs, low ceilings, and fieldstone or block walls, so clear a path to the equipment and the tank before the contractor arrives.
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.
For an oil burner, verify the technician's certificate with the Department of Fire Services. For gas appliances, check the gas fitter license on the state's occupational license lookup.
Before someone heads out, ask when they can realistically arrive and how after-hours or diagnostic visits are billed, so there are no surprises.
If the technician recommends replacement, ask for a written estimate covering equipment, permits, and removal, and for a temporary fix if one is safe, so you can compare options in daylight.
Costs
The hour and the cause matter most. A night or weekend visit to replace an igniter is a different bill from an oil tank that needs replacing with a Fire Department permit, or a boiler whose controls sat in groundwater. Age matters too: parts for older equipment may not be on the truck.
Ask how the visit is charged before work begins, and get anything beyond the immediate repair in a written estimate. If the system is near the end of its life, it can be worth pairing the repair with a conversation about Mass Save offers through Eversource or National Grid before replacing it in a hurry.

Questions
Still not sure? Send a short request and a local pro can answer the specifics.
Press it once at most. If the burner doesn't stay lit, leave it off, because repeated resets can push extra oil into the chamber. Check the tank gauge, then call a heating contractor.
Leave the house first. From outside, call 911 or National Grid, which supplies Milton's natural gas. A heating contractor comes after the gas company or fire department says it's safe.
That depends on the contractors' schedules and the part needed, and we can't promise a time. When you call, you'll be connected with an independent local heating contractor who can tell you when they're able to come.
Yes. Milton's Fire Department issues oil burner and oil tank installation and removal permits on form FP-056. The contractor doing the work should file it, even when the job is urgent.
Not until a professional has checked it. Water can damage the burner, controls, and wiring without visible signs. Keep the system off, stay clear of standing water near electrical equipment, and tell the contractor how high the water came.
