Eight months of heat puts a lot of hours on your furnace
From October through May your furnace is the thing standing between your house and a 26°F night. That is eight months a year it has to work, not just a few cold snaps. Every one of those nights it cycles on and off to hold the temperature, and each start puts a little more wear on the igniter and the burner.
44% of homes here heat with fuel oil, and an oil furnace has its own parts that fail with that kind of use, like a clogged nozzle or a dirty filter starving the burner of fuel. This area has seen 82 winter storms and 434 damaging wind events over the last ten years, and the power behind your furnace is not always reliable either. Statewide, 11% of households lost power for at least a day in 2024, and a furnace will not restart on its own once the power comes back. If yours has gone quiet on a cold night, it may need more than a reset.

- Why won't my furnace turn on?
- Most often the thermostat isn't calling for heat the way you think it is, or power isn't reaching the furnace. Check that the thermostat is set above 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, the igniter or a safety switch may be at fault, and that's a job for a contractor to diagnose.
- Why is my furnace blowing cold air?
- If air is moving but it's not warm, the furnace may be running the blower without the burners lighting. Start with the thermostat fan setting. If it's set to "on" instead of "auto", the blower runs constantly and pushes room-temperature air between heating cycles, which feels cold even when nothing is wrong. If the fan is set to auto and you're still getting cold air, something is preventing ignition, and a contractor will need to look at it.
- Why won't my furnace pilot light stay lit?
- A pilot light that won't stay lit usually means the thermocouple isn't sensing the flame anymore, so the gas valve shuts back off. It can also mean a draft is blowing the flame out, or the pilot orifice is partly clogged. This isn't something to keep relighting on your own since it's tied to the gas supply. A contractor can tell which of these it is and replace the part that's failing.
