Heating Repair & Installation in Cohasset, MA
Natural gas does not reach every Cohasset street, so a good share of the town — including the larger homes along Jerusalem Road, Atlantic Avenue and around the harbor — heats with oil or propane, often through multi-zone boilers carrying serious loads. Add coastal weather and a real share of seasonally occupied houses, and Cohasset heating rewards a company that plans ahead instead of just reacting.

Replacing an oil system in Cohasset
When an oil boiler reaches end of life and there is no gas main to connect to, you have three real options: another oil system, propane, or a cold-climate heat pump. Each has a very different install cost and operating cost, and the right answer depends on your house rather than on what a contractor prefers to sell. We price the options side by side, including the Mass Save incentives that apply when you come off oil — often the larger whole-home numbers — plus the 0% HEAT Loan on qualifying projects.
Big houses, multiple zones, aging boilers
Estate-scale Cohasset homes run boilers feeding many zones and heavy hot-water demand, and a boiler carrying that load past year twenty is on borrowed time. We handle repair honestly when repair makes sense; when it doesn’t, we replace with properly piped high-efficiency equipment sized to a real heat-loss calculation, with indirect tanks matched to the household.
Freeze protection for houses that sit empty
A heating failure in an empty coastal house in January is a burst pipe waiting to happen. For seasonal and travel-heavy households we set up Wi-Fi thermostats with low-temperature alerts, recommend leak-shutoff valves, and schedule annual maintenance around the calendar the house actually keeps.

Cohasset questions we hear
What should the thermostat be set to when we’re away? 55°F minimum, with a Wi-Fi thermostat alerting below 50 — and cabinet doors open on exterior-wall plumbing. Better yet, pair it with a leak-shutoff valve.
Oil, propane, or heat pump for the replacement? Depends on your street’s gas access, your tank situation, and the house’s load. Cohasset gets full Mass Save incentives, so the heat pump path deserves a real look — run the rebate calculator for a starting number.
How long should a boiler last here? 20–30 years for cast iron with annual service. Salt air and damp ocean-facing basements shorten the life of everything mechanical — maintenance is the difference.
