Hanover · No Heat
Hanover boiler down and baseboards going cold? Leave first for gas, propane, or CO, protect the heating pipes from freezing, then call to reach an independent heating contractor.
Hanover, Massachusetts
Hanover grew quickly in the 1950s and 1960s, and more than a third of its homes date from those two decades. Many houses from that era heat with a boiler pushing hot water through fin-tube baseboard, and that water sits in pipes that run along outside walls, under windows, and sometimes through additions and sunrooms built later. When the boiler stops in a deep cold snap, those loops are what freeze first.
Hanover also leans heavily on oil and uses very little electric heat, so most no-heat calls here involve a burner and a fuel supply. If you smell gas or propane, or a carbon monoxide alarm sounds, get outside and call 911. Propane customers should also call their supplier from outside.
When the house is safe, call or send a request and South Shore HVAC Finder will connect you with an independent heating contractor who works in Hanover. The contractor gives the estimate and does the repair; we don't.
If baseboard in the coldest rooms stays cold while the boiler is off, those pipes can freeze during a deep cold snap.
Rooms added onto older houses often have the longest, most exposed heating runs and drop in temperature first.
Water leaking from the boiler or a relief valve, or pressure that keeps climbing, needs a technician before the boiler runs again.
Propane settles low; an oil smell can mean a leak at the tank or line. Either is a reason to leave and call.
Local knowledge
Fuel, house age, and the local fire rules shape what to do when the heat stops in Hanover.
Oil-Heavy Town
Half of occupied Hanover homes use utility gas, but 36 percent burn fuel oil and fewer than 10 percent heat with electricity, according to 2020-2024 Census estimates. That makes the oil tank gauge and the burner reset part of most Hanover households' first checks.

Roads In Floods
During the March 2010 storms, King Street was closed for two to three days at the Forge Pond bridge, affecting every house on it and the side roads south of the bridge. If your road can flood, plan ahead for fuel and for a technician who may not reach you right away.

Burner And Tank Forms
Installing an oil burner or removing or replacing an oil tank in Hanover requires a Form 1, completed by a holder of the state oil burner certificate, followed by a fire department inspection. Propane storage and installation call for a separate FP 06 filing.

Right now
Take these in order, starting with safety.
Get everyone and the pets out and call 911 from outside. If you heat with propane, call your supplier too, once you're a safe distance away.
Make sure the boiler's emergency switch is on and the oil or propane tank isn't empty. One press of an oil burner's reset is enough; more can flood it.
Open doors to sunrooms, additions, and rooms over the garage so house heat can reach them, and open cabinet doors on outside walls.
If a baseboard pipe or water line has frozen, never use a torch or open flame on it. Tell the contractor where you think the freeze is.
What to expect
With a hot water boiler, a technician usually checks the burner, the circulator pump, the system pressure, and the expansion tank, then looks for any zone that froze or air-locked. A frozen baseboard loop can split, so expect them to look for leaks before the system refills and runs.
If the burner or tank has to be replaced, Hanover's fire department needs a Form 1 from someone holding the state oil burner certificate and then inspects the work. Gas and plumbing permits go through Building and Inspectional Services on the town's OpenGov portal. Ask your contractor which permits they'll pull.
Make the boiler, tank, and any cold zones easy to reach. In additions or finished basements, know where the baseboard runs and any access panels are.
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.
Hot water baseboard is its own skill set. Ask whether the company services boilers and can deal with frozen or air-bound zones.
Oil burner work needs a Department of Fire Services certificate, and propane or natural gas work a Massachusetts gas fitter license. Verify the right one online before work begins.
If a pipe split, ask for a written description of what failed and what was repaired. It helps with insurance and with planning any later upgrade.
Costs
A burner that just needs a restart is a small job compared with thawing and repairing a frozen heating loop or replacing a split baseboard section. Older boilers, harder access in additions, and night or weekend timing all play a part.
Ask how the visit is billed before you book, and get a written estimate before work beyond the diagnosis. If replacement of the boiler comes up, ask for a repair option as well, so you can compare once the heat is back on.

Still not sure? Send a short request and a local pro can answer the specifics.
Yes. Baseboard loops that run along outside walls, under windows, or through additions can freeze if the boiler is off long enough in deep cold. Open doors to those rooms and call for help quickly.
Plan for a delay. In March 2010 King Street was closed for days at the Forge Pond bridge. Keep the fuel tank well above empty during storm season and make sure you have a safe backup plan for staying warm.
Someone holding the state oil burner certificate, typically the contractor doing the work. The fire department then inspects the installation. Ask your contractor to confirm they'll handle both.
It can be if heating pipes run through it. A room that keeps dropping in temperature while the rest of the house is warm can mean a zone isn't circulating, which risks a freeze. Call to be connected with a local heating contractor.
