Seven months of heat puts real wear on a Chestertown furnace
From October through April, your furnace is the thing standing between you and a 28°F night. That is seven months of the burner lighting, running, and shutting off, night after night. Each cycle puts a little more wear on the igniter and the parts that start the burner. When one of those finally gives out, the furnace won't light at all.
Kent County has seen 8 winter storms and 98 damaging wind events over the past ten years, and storms like these knock out power along with the heat. Most homes here run on electric heat, so a power outage means the furnace stops too. Across Maryland, 11% of households lost power for 24 hours or more in 2024. When the power comes back on, most furnaces restart on their own, but if yours doesn't, that's worth a call.

Maryland requires HVAC contractors to hold a state license.
Maryland issues that license through the Board of Heating, Ventilation, Air Conditioning, and Refrigeration Contractors. The license covers the contractor, not each job, so it belongs to the person or business, not to this one repair.
For a furnace repair, that license is what backs the person working in your house. A bad gas connection is the dangerous part of this job, and the license is what ties that work to a contractor the state has on record.

- Why won't my furnace turn on?
- Start with the thermostat. Make sure it's set to heat and the temperature is set above room temperature, since a setting bumped a degree or two can look like a dead furnace. Check the power switch on the furnace itself, usually near the unit and shaped like a light switch, and check the breaker. If those are fine, the igniter or a safety switch may be keeping the furnace from starting, and that calls for a contractor to test.
- Why is my furnace blowing cold air?
- Most often the blower is running before the burners have caught up, which is normal for the first minute or so after startup. If cold air keeps coming and never warms, the igniter may not be lighting the burners, or the gas valve isn't opening. A dirty filter can also choke airflow enough that what reaches the vents feels cool. If the furnace runs but never produces heat, that points to something a contractor needs to diagnose.
- Why won't my furnace pilot light stay lit?
- This usually means the thermocouple has worn out and can no longer sense that the pilot is lit, so it shuts the gas off as a safety measure. A draft blowing across the pilot can also snuff it out, and a dirty pilot orifice can make the flame too weak to hold. A standing pilot doesn't use electricity, so a power outage isn't the cause. If relighting it keeps failing, the thermocouple likely needs replacing.
