Eight months of heat, and a grid that doesn't always hold

Vineyard Haven needs a furnace for eight months of the year, October through May. Winter nights average 27°F, so the burner is cycling on and off most nights for a good chunk of the year. A furnace built for that kind of run time matters more here than in a place where heat is only an occasional thing.

Any non-weatherized gas furnace made since November 2015 has to hit at least 80 percent AFUE, so that is the floor, not a selling point. Power is worth planning around too. Across Massachusetts, one household in ten lost power for 24 hours or more in 2024, and the past ten years brought 13 winter storms and 46 damaging wind events to this area. A furnace that needs electricity to run its blower and ignition is only as reliable as the power behind it.

Estimates for a typical Dukes County home, from EIA household energy data, Massachusetts fuel prices and NOAA climate normals. Your home will differ.

What size furnace does my house need?: The right size depends on your home's square footage, how it's insulated, your window count, and your ceiling height, so there isn't one answer that fits every house. A contractor works this out with a load calculation, not a chart based on floor space alone. This matters more here than in milder places, since your furnace has to hold its own from October through May with winter nights averaging 27°F. Too big and it short cycles, too small and it can't keep up on the coldest nights.
How do I know it's time to replace my furnace?: Rising repair bills, uneven heat between rooms, and a furnace that's old and struggling are the main signs. If yours is cycling more often, making new noises, or the burner flame looks yellow instead of blue, have it looked at. With heat needed here from October through May, a furnace that's already struggling early in the season is only going to have more months ahead of it to get through. A contractor can tell you whether another repair makes sense or whether you're better off replacing it now.
Is a high-efficiency furnace worth it?: It depends on how many months a year you're running it and what you're replacing. Since homes here need heat from October through May, a high-efficiency furnace has more months to earn back the difference in fuel use than it would somewhere with a short winter. Any new non-weatherized gas furnace has to hit at least 80 percent AFUE by law, but higher-efficiency models go well past that, using less fuel for the same heat. A contractor can walk you through the options and what fits your house and your fuel type, since 40 percent of homes here heat with propane, where every percentage point of efficiency shows up on the bill.
