Seven months of heat, and cold nights to match
Your furnace works from October through April here, seven months of the year. On winter nights that average 28°F, it cycles on and off for hours at a stretch, and every cycle puts a little more wear on the igniter and the burner. When one of those parts finally gives out, it usually happens on a night like that, not a mild one.
Power matters too. Across New York, 11% of households lost power for a full day or more in 2024, and the area has seen 14 winter storms and 32 damaging wind events over the past ten years. A furnace with no power will not run no matter how sound its parts are, and some need a reset before they fire again once power comes back.

A new furnace would cut about $120 a year off heating for a typical New York County home.

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 it's the thermostat not calling for heat, a tripped breaker, or the switch that looks like a light switch near the furnace turned off. Check the thermostat is set above room temperature and on heat, not just fan. If the breaker's fine and the switch is on, the igniter or flame sensor could be failing to prove a flame, and the furnace shuts itself down as a safety step. A contractor can tell you which it is once they're looking at it.
- Why is my furnace blowing cold air?
- If air is running but it's not warm, the furnace may be in a startup cycle where the blower runs before the burners light, which lasts a minute or so. If cold air keeps coming, the igniter may not be lighting the burners at all, or the thermostat fan setting is stuck on. With nights averaging 28°F here through the winter, cold air blowing for more than a few minutes means something needs a look, not a wait.
- Why won't my furnace pilot light stay lit?
- A pilot that won't stay lit is usually the thermocouple, the small rod that sits in the flame and tells the gas valve the pilot is burning. When it wears out it stops sending that signal and the valve shuts the gas off. A draft blowing out the pilot or a dirty pilot orifice can cause the same thing. Either way it's a part a contractor replaces or clears, not something to keep relighting through the winter.
