Eight months of heat, off an island grid

Vineyard Haven asks for heat from October through May. On winter nights averaging 27°F, the furnace is cycling on and off for most of the day and night, and every one of those starts puts wear on the igniter and the ignition control. When one of those parts finally gives out, the burner won't light at all.

A lot of homes here run on propane, and propane furnaces depend on power to run the igniter, the blower, and the control board. The county has seen 13 winter storms and 46 damaging wind events over the past ten years, and across Massachusetts about 1 in 10 households lost power for 24 hours or more in 2024. When the power drops on a cold night, a furnace that was already struggling to light often doesn't come back on its own.

A new furnace would cut about $260 a year off heating for a typical Dukes County home.

  • A new high-efficiency furnace$1,060 a year
  • An older furnace$1,320 a year

Estimates for a typical Dukes County home, compared with an older unit built to the previous federal minimum, from EIA household energy data, Massachusetts fuel prices and NOAA climate normals. Your home will differ.

Repair makes sense when one part has failed and the heat exchanger is sound.

Replacement makes sense when the heat exchanger is cracked or the furnace keeps needing parts.

Why won't my furnace turn on?
Most often the thermostat isn't calling for heat the way it should, or power to the furnace has been interrupted. Check that the thermostat is set below room temperature and has fresh batteries if it uses them. Next check the furnace switch, which looks like a light switch near the unit, and the breaker for it. If those are fine, a safety switch inside the furnace may have tripped, and that calls for a contractor to find out why.
Why is my furnace blowing cold air?
If the air feels cold but the house is slowly warming up, that's normal. A furnace pushes air across a heat exchanger that takes a minute or two to warm up, so the first air out of the vents will feel cool. If the air stays cold the whole time the furnace runs, the burners may not be lighting even though the blower is, and that needs a contractor to check the ignition system. A dirty filter can also choke off airflow enough to trip a safety limit and leave the blower running with no heat behind it.
Why won't my furnace pilot light stay lit?
This usually means the thermocouple isn't sensing the flame, so the gas valve shuts back off to protect the house. Dirt or soot on the thermocouple, or the thermocouple wearing out, are the common causes. A draft blowing across the pilot can also blow it out before the thermocouple can read it. With 40% of homes here heating with propane, a pilot that won't hold is worth having looked at soon, since propane furnaces depend on that pilot for every ignition.
