Cold radiators in East Weymouth or a heat pump question in South Weymouth? Call or send a request to get connected with an independent HVAC contractor who serves Weymouth.
Weymouth, Massachusetts
Most Weymouth houses are older than the systems that heat them. The town's 2026 Housing Production Plan says almost two thirds of homes were built before 1960, so radiators, old chimneys and ductwork added decades after the house was framed are often part of the picture when you call about heat or air conditioning.
South Shore HVAC Finder connects Weymouth homeowners with independent HVAC contractors who serve the town. We don't do the work, set prices or inspect jobs. You describe the problem by phone or with a short request, get connected with a local contractor and decide for yourself whether to hire them.
Safety comes before comfort. If you smell gas, hear a carbon monoxide alarm or feel dizzy near a furnace or boiler, leave the house and call 911 or National Grid from outside. Don't restart equipment or relight anything until a qualified person has checked it.
Local knowledge
Your utility, your home's age and the town's permit process all affect heating and cooling decisions in Weymouth.
National Grid Gas And Power
State utility listings show National Grid, through Boston Gas and Massachusetts Electric, serving Weymouth. National Grid is a Mass Save sponsor, so Weymouth customers can look to Mass Save for home energy assessments and heating and cooling rebates.

Community Electricity
The town runs Weymouth Community Electricity, an aggregation that buys electricity supply while National Grid still delivers the power. Eligible customers were auto-enrolled starting with October 2025 meter reads, so check your bill to see which supply rate you're on before comparing heat pump operating costs.

Older Housing
Weymouth has 5,799 housing units built in 1939 or earlier and many more from the 1950s. Houses of that age often started with boilers and radiators, and some still have them, so piping, chimneys that once vented oil equipment and uninsulated attics are worth checking when you upgrade.
Oil Burner Paperwork
Weymouth Fire Prevention takes applications by email, including Form 1 for oil burners, tank removal and tank installation, plus underground storage tank removal. If you're switching away from oil, ask your contractor who will file the tank removal paperwork.

Storm History
The town's 2021 Hazard Mitigation Plan lists 37 repetitive-loss properties with 115 flood losses from 1978 to 2020, and the March 2018 winter storm and flooding was a federally declared disaster that included Norfolk County. Basement furnaces and boilers in low areas such as Idlewell along the Fore River are the ones most worth raising or protecting.
Services
Independent contractors who serve Weymouth work on older boilers, newer heat pumps and everything in between. Here's how each service usually fits a Weymouth home.
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.
Ask which licenses the job needs: a gas fitter license for gas lines, a sheet metal license for ductwork or a Department of Fire Services certificate for oil burner work. Gas fitter and sheet metal licenses appear on the state's occupational license lookup, and oil burner certificates on the DFS verification site. Source
Gas and installation permits go through Weymouth's Department of Municipal Licenses and Inspections on Middle Street, and oil burner work also needs a Fire Prevention application. Ask the contractor to list every permit in the estimate. Source
A home energy assessment through Mass Save can point out air leaks and insulation gaps before you replace equipment, which makes it a sensible first step for National Grid customers planning a heat pump. Confirm current rebate terms on the Mass Save site. Source
The estimate should name the equipment, its efficiency rating, any ductwork or piping changes and removal of the old system. Ask how the contractor calculated the size, especially for a house with additions.
Any new gas or oil appliance should come with working carbon monoxide alarms. Weymouth Fire Prevention posts the town's smoke and CO alarm requirements, so ask the contractor whether your alarms meet them. Source
Costs
In older Weymouth homes, the hidden work can cost more than the equipment itself. Removing an old oil tank, relining a chimney, adding circuits for a heat pump or running new ducts through finished rooms can all change the estimate.
Ask each contractor to break out equipment, labor, permits and removal of the old system. If you're counting on Mass Save rebates, confirm the current terms yourself and ask whether the quote assumes you'll receive them.
Repairs depend on parts and timing. A part for an older boiler may take time to find, so ask whether the contractor can make a temporary repair while you wait.
Neighborhoods and nearby
Contractors who serve Weymouth typically cover all four village centers and the neighborhoods around them. Braintree is about 9 minutes away by car, Holbrook about 14 and Rockland about 16.
Questions
Still not sure? Send a short request and a local pro can answer the specifics.
Cost depends on the size of the home, how many zones you need, whether ductwork exists and how well the house holds heat. Ask for written estimates from more than one contractor, and check Mass Save for National Grid rebates before you compare totals.
If there's a gas smell or a CO alarm is sounding, get everyone outside and call 911 from there. If not, check the thermostat, the power switch near the unit and the breaker. Then call or send a request to reach an independent contractor who serves Weymouth; how fast someone can come depends on demand that night.
Weymouth's Department of Municipal Licenses and Inspections handles gas and building permits, and the Fire Department's Fire Prevention Division handles oil burner and tank applications. Your contractor normally files them, but you can ask to see the permit before work starts.
It can if you heat with electricity. The town's aggregation sets the electricity supply rate for enrolled customers, while National Grid delivers the power and handles outages. Check your bill to see which supply you're on when comparing a heat pump with gas or oil.
Radiators can work well with a modern boiler, and some homes add a heat pump or mini-splits for cooling and mild-weather heat. Ask a contractor to look at the boiler's condition, the piping and the chimney before you decide.
