Eight months of heat, and a lot of cold nights in between
Your furnace in Yonkers works from October through May. That is eight months a year of the burner lighting, running, shutting off, and lighting again, night after night. On winter nights that average 24°F, it cycles more often to keep up, and every cycle puts wear on the igniter and the flame sensor.
Westchester County has seen 42 winter storms and 167 damaging wind events over the past ten years. Wind and ice bring down power lines, and when the power goes out, so does your furnace, even if the gas is still on. Most furnaces start back up on their own once power returns, but if yours does not, that is worth a call.

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?
- The most common cause is the thermostat, the power supply, or the gas supply to the unit. Check that the thermostat is set to heat and above room temperature, and that the furnace switch and breaker are both on. If those check out, the igniter or flame sensor may have failed, or a safety switch has shut the furnace down. A contractor can test each of these to find where the problem is.
- Why is my furnace blowing cold air?
- If the blower is running but the air feels cold, the furnace likely isn't igniting the gas, even though the fan still moves air through the ducts. This can happen if the igniter is worn out, the flame sensor is dirty, or the gas valve isn't opening. It can also mean the furnace is in the middle of its startup cycle, when the blower runs a few seconds before the burners fire. If cold air keeps blowing during a heating cycle, the burners need a contractor to look at them.
- Why won't my furnace pilot light stay lit?
- A pilot light that won't stay lit usually means the thermocouple has worn out and can no longer hold the gas valve open. It can also mean the pilot tube is clogged, or a draft in the area is blowing the flame out. A standing pilot doesn't use electricity, so a power outage isn't the cause. This is a common repair, and a contractor can replace the thermocouple or clear the line so the pilot holds.
