What Should South Shore Homeowners Do When the Heat Goes Out?

When the heat goes out in a South Shore home, the immediate concern is comfort. The next concern is frozen plumbing. Older homes in Quincy, Abington, Weymouth, Braintree, and nearby communities may have pipes running through exterior walls, unfinished basements, crawl spaces, garages, or other cold areas. If the temperature stays low, a heating failure can lead to burst pipes and water damage.

Start with safety, then determine whether the problem is limited to the heating equipment or is affecting the plumbing throughout the house.

What should you check first when the heat stops?

• Check the thermostat. Confirm it is set to heat, the temperature is above the current room temperature, and the display has power.
• Check whether the electrical service is on. If the whole house is without power, do not repeatedly reset breakers.
• Look at the boiler or furnace for an error light, warning message, unusual noise, or visible water.
• Check the fuel supply if your home uses oil or propane. Do not open fuel lines or attempt to repair combustion equipment.
• Check whether radiators, baseboards, or vents are cold throughout the house or only in one area.

If you smell gas, leave the building and call 911 or your gas utility from a safe location. Do not operate switches, use an open flame, or stay inside trying to locate the leak. The Massachusetts gas safety guidance has additional safety information.

How can you protect South Shore plumbing during a heating outage?

If the home is getting colder, open cabinet doors below sinks on exterior walls so warmer room air can reach the supply pipes. Keep interior doors open where practical. If safe to do so, allow a small stream of water from vulnerable faucets; moving water may reduce the chance of freezing, but it is not a substitute for restoring heat.

Locate the main water shutoff before a pipe bursts. In many South Shore homes, it is near the water meter where the service enters the basement. Make sure everyone in the household knows how to turn it clockwise. If you see a split pipe, active leak, or water near electrical equipment, shut off the water if you can do so safely and call for plumbing help.

Do not use a torch, open flame, space heater aimed at a pipe, or heating device near insulation, wiring, fuel, or water. A frozen pipe may already be cracked even if it is not leaking yet. When it thaws, the damage can become obvious quickly.

Is a boiler problem always a plumbing emergency?

Not every heating failure requires a plumber. A boiler may need a heating specialist, while a furnace or electrical heating system may require a different trade. However, a boiler also connects to the home’s water and hydronic heating system. Leaking pressure-relief valves, failed circulator components, low system pressure, damaged pipes, and water around the boiler can require plumbing attention.

If the boiler pressure is low, do not keep adding water unless the equipment instructions specifically direct you and you understand the procedure. Repeatedly resetting a boiler can hide a fault. Record the error code and take a photo for the technician. That information can make the diagnosis more efficient.

When should you call for emergency plumbing help?

Call for help promptly if a heating outage is accompanied by a burst or leaking pipe, water pooling near the boiler, a failed circulator with leaking fittings, no hot water from a boiler-related system, or a basement drain backup. Plumbing issues can worsen while you are waiting for a separate heating diagnosis.

For a heating-only failure with no leak, contact the company that services your boiler, furnace, heat pump, or oil system. If you are unsure who to call, search for who to call to fix a boiler or who services a boiler, then confirm that the provider works on your equipment type. A plumber can address connected water, piping, and leak problems, but should not promise to repair every type of heating equipment.

What information should you have ready?

• Your town and the age or type of the home.
• Whether the system is a boiler, furnace, heat pump, or another type.
• The fuel source, if known.
• The equipment brand and model.
• Any displayed error code or warning light.
• Whether there is leaking water, frozen piping, or loss of hot water.
• Whether the main water shutoff is accessible.
