Hanover has better natural gas coverage than most of the towns we serve, and that changes the conversation. In Norwell or Hanson the real decision is oil versus electric. In Hanover, if the main runs down your street, a gas conversion is genuinely on the table — and it is often the best money a homeowner still burning oil can spend.

Oil to gas, honestly assessed

The first question is not what equipment you want — it is whether gas actually reaches your property, and what it costs to get from the street into the house. Along the Route 53 corridor, Assinippi and much of West Hanover, service is generally available. Farther out toward the Rockland and Hanson lines it thins out. We confirm availability with the utility before we quote anything, because a conversion estimate that ignores the service line is not an estimate.

When it pencils out, the project is a high-efficiency gas boiler or furnace, permitted gas piping run under a Massachusetts Master Plumber license, a new venting path, and removal of the old oil tank. That last item matters — an abandoned tank left in a basement or buried in a yard is a liability, not a saving.

Hanover’s housing stock is mostly one era

A large share of Hanover is 1970s through 1990s colonials and splits, which is genuinely good news for heating work. The distribution is usually forced hot water baseboard or ducted warm air in reasonable condition, the mechanical rooms are accessible, and the systems were installed to a recognizable standard. That means replacements are predictable and we are rarely undoing somebody’s improvisation.

What we do find: original equipment now well past 30 years, boilers oversized because they were sized off the previous nameplate instead of the house, and single-zone systems in houses that should have two or three. We size to a heat loss calculation. An oversized boiler short-cycles, wears out its own controls, and heats unevenly — bigger is not a margin of safety, it is a defect.

Where gas does not reach

If your street has no main, the choice is a new oil or propane system versus going electric. Hanover is on an investor-owned utility, so the full Mass Save incentives apply, and a house paying for delivered fuel is exactly the scenario those rebates were built for. We will put both columns in front of you — total annual energy cost, not just install price — and you can run your own numbers first with the rebate calculator.

There is also a third answer we give often: repair it. A boiler in its teens with a failed circulator, zone valve or aquastat is a repair, not a replacement. We would rather fix it now and earn the replacement when it is actually time.

What we handle in Hanover

We install and service Navien, Laars, Lochinvar and Viessmann hydronics, and pipe them properly — which matters more for longevity than the badge on the front.

Hanover questions we hear

Is gas cheaper than oil right now? Generally yes on a per-BTU basis, but the honest answer depends on the year and on what the service line costs you. We show you the payback period rather than asserting the conclusion.

Should I convert to gas or go heat pump? If gas is at the street and your ductwork or baseboard is sound, gas is usually the lower-risk choice. If you also want air conditioning you do not currently have, a heat pump does both jobs and collects rebates gas cannot. We quote both.

My boiler is 30 years old and runs fine — why replace it? Because it will not fail in October. It will fail at 2am in January and you will make a rushed five-figure decision on the worst possible night. Planning it in the fall costs the same money.
