Nine months of heat, and nights near 14 degrees
Furnaces in Laconia run from September through May. That's nine months of cycling on and off, night after night, with winter lows that average 14°F. A furnace working that hard wears on the parts that start it and keep it running, like the igniter, the flame sensor, and the blower motor.
Almost half the homes here heat with fuel oil, and an oil furnace still needs electricity to run its blower and ignition. Belknap County has logged 44 winter storms and 38 damaging wind events over the past ten years, and statewide, 22% of households went at least a day without power in 2024. When the power drops during a cold snap, the furnace stops with it, and most units come back on by themselves once power returns.

New Hampshire has no state license for HVAC contractors.
There is no state license or registration behind the name on the van. New Hampshire does not test HVAC contractors, does not keep a list of them, and does not put anything on record before someone shows up to work on your furnace.
Gas is the part of a furnace repair that has to be done right, and in New Hampshire that check does not come from a license, because there isn't one to check. Whatever stands between you and a bad repair on this job has to come from the person doing the work, not from anything the state keeps on file.

- Why won't my furnace turn on?
- Start with the thermostat. Check that it's set to heat and the temperature is above room temperature, and check that it has power or fresh batteries. If the thermostat looks fine, check the furnace switch, usually near the unit and shaped like a light switch, and check the breaker for the furnace. Furnaces with a standing pilot won't run if the pilot has gone out, and furnaces with an electronic igniter won't run if the igniter has failed. If power and the thermostat both check out and the furnace still won't start, a contractor will need to look at it.
- Why is my furnace blowing cold air?
- Most often this means the blower is running but the burners haven't lit. The blower can start before the air has had time to warm up, so a few seconds of cool air at startup is normal. If cool air keeps blowing the whole time the furnace runs, the burners likely aren't igniting, which can come from a dirty flame sensor or a failed igniter. A clogged filter can also cause this by restricting airflow and putting out the burners early. Given how cold nights get here, a furnace that only blows cold air needs attention right away, not something to wait out.
- Why won't my furnace pilot light stay lit?
- This usually points to the thermocouple, the small part that senses the pilot flame and keeps gas flowing to it. When it wears out or sits out of position, it shuts the gas off even though the pilot is lit, and the flame goes out. A draft near the pilot or a dirty pilot orifice can cause the same thing. A thermocouple is a low-cost part to replace, but keep in mind a standing pilot furnace runs without needing power, so if yours keeps going out it's a mechanical issue with the pilot assembly, not an electrical one.
