Avon · No Heat
No heat in Avon tonight? Leave first for gas or CO, check the oil gauge or the gas meter, then call to reach an independent heating contractor who serves Avon.
Avon, Massachusetts
A cold house in Avon is about as likely to trace back to an oil tank as to a gas line. Recent Census estimates show roughly a third of occupied homes in town heating with fuel oil and just under half with utility gas, so before you blame the boiler, it helps to know which fuel feeds it and whether that fuel is actually reaching the burner.
Safety outranks the thermostat. A carbon monoxide alarm, a smell of gas, or smoke from the burner means everyone leaves the house right away, and the call to 911 or Eversource happens from outside. Avon Fire Department headquarters sits on Main Street, and responders would rather check an empty house than a full one.
Once everyone is safe, or if the problem is simply a cold house, call or send a request. South Shore HVAC Finder connects Avon homeowners with independent heating contractors; we don't make the repair, and the contractor you reach sets their own schedule and rates.
A burner that stops and shows a red reset light again and again is protecting itself. Pressing reset repeatedly can flood the chamber with oil, so stop after one try.
Black streaks around the burner door or a strong oil smell in the basement can mean poor combustion. Turn the boiler off at the red-plated switch and phone for help.
Treat any carbon monoxide alarm as real until someone with a meter says otherwise. Get out first and call 911 from outside.
When indoor temperatures fall quickly in a hard freeze, water pipes in outside walls and crawl spaces are at risk, which turns a heating problem into a plumbing one.
Local knowledge
These details decide where an Avon homeowner should look first when the heat stops.
Oil Burners
Census figures for 2020 to 2024 put fuel oil or kerosene at 34.5% of occupied Avon homes. An oil system can stop for simple reasons, like an empty tank or a clogged filter, and for serious ones, so mention the tank level and any reset attempts when you call.

Gas From Eversource
Avon's natural gas is delivered by Eversource, and close to half of homes in town heat with it. A gas odor gets reported to 911 or Eversource from outdoors; never relight a gas appliance yourself after a smell or an outage.

Winter Storm History
Norfolk County, which includes Avon, was declared a federal disaster area after the January 26 to 28, 2015 storm and again after the January 28 to 29, 2022 snowstorm. Deep snow can bury the exhaust and intake pipes of high-efficiency furnaces and boilers, which can shut the unit down or push exhaust back toward the house.

Right now
Work down this list in order, and skip anything that doesn't feel safe.
Leave with everyone, pets included, and call 911 or Eversource once you're outdoors. Don't flip switches or use the phone inside if you smell gas.
Oil tanks carry a float gauge on top, usually a small clear dome. If the float sits at the bottom, call your oil supplier before the heating contractor, and ask whether the burner will need to be bled after the delivery.
Confirm the thermostat is set to heat and has working batteries, and that the red-plated emergency switch at the top of the basement stairs is on. Someone may have bumped it.
Walk outside and brush snow away from any plastic exhaust or intake pipes on the side of the house. Keep them clear until the storm ends.
Open cabinet doors under sinks on outside walls and let a faucet drip slowly. Use only space heaters made for indoor use, keep them clear of anything that burns, and never heat the house with an oven or grill.
What to expect
On an oil system, expect the technician to check the fuel supply, filter, nozzle, and ignition before condemning anything bigger. On gas, they will look at the igniter, flame sensor, venting, and pressure switch. Either way, ask them to explain what failed and whether the fix is temporary.
A straight repair usually needs no permit, but a replacement does. In Avon, gas appliance work is permitted through the plumbing and gas inspector, and installing or altering oil-fired or other fuel-burning equipment needs an Avon Fire Department permit. Both are filed online in PermitEyes, since the town no longer takes paper applications.
Clear a path to the boiler or furnace and the oil tank before the technician arrives, and have the model and any error codes written down. If the old unit has to come out of a tight basement, ask whether replacement can wait for daylight while a temporary fix keeps the house warm.
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.
An oil burner job needs a technician with a Massachusetts Department of Fire Services certificate, and gas work needs a gas fitter license. The DFS verification site and the state's occupational license check let you confirm either one.
Before booking, ask whether there is a trip or diagnostic charge and how night or weekend work is billed, so nothing surprises you later.
If the technician recommends a new boiler or furnace, ask for the written estimate and the permit plan before agreeing. A cold night is a hard time to compare fuel options.
Costs
The fuel and the failure set the price more than anything. Bleeding an oil line after a run-out, replacing a gas igniter, and swapping a cracked heat exchanger are very different jobs. The hour of the call, the parts the technician carries, and how hard the equipment is to reach in an older Avon basement all play in.
Ask for the diagnosis in plain words and a written estimate before work beyond the first visit. If replacement is on the table, ask for a second written quote once the heat is back on, and compare scope rather than the total alone.

Call your oil supplier for a delivery first. After a run-out, the burner may draw sludge or air and need to be bled or have its filter changed, so if it doesn't restart after one reset, call a heating contractor.
Once. If the burner fires and stops again, leave it off and call. Repeated resets can pump unburned oil into the combustion chamber, which makes the next start dangerous.
Brush the snow away from the plastic pipes on the outside wall and keep them clear. If a CO alarm sounded or the house smells of exhaust, get everyone out and call 911 before going near the vents.
