Seven months of heat, and storms that cut the power
Princess Anne needs the furnace running from October through April, seven months of the year. On winter nights that average 30°F, the burner is cycling on and off for hours at a stretch, and every start puts wear on the igniter and the flame sensor. When one of those fails, the furnace won't light at all.
56.4% of homes here heat with electricity, so when the power goes out, the heat goes with it. Somerset County has seen 11 winter storms and 29 damaging wind events over the past ten years, and across Maryland, 11% of households went at least 24 hours without power in 2024. A furnace that was struggling before an outage often won't restart cleanly once the power comes back.

Maryland requires HVAC contractors to hold a state license.
The Maryland Board of Heating, Ventilation, Air Conditioning, and Refrigeration Contractors tests contractors before granting this license, and it keeps a record of who is licensed to work in the state. The license belongs to the contractor, not to the job, so it covers this furnace repair the same way it covers an install or a duct job.
A furnace repair often means opening a line that carries gas, and a loose or bad connection there is what makes the job dangerous rather than just inconvenient. In Maryland, that work falls under the same license the state requires for any HVACR contractor, tested and on record with the board.

- Why won't my furnace turn on?
- Most often the thermostat is asking for heat but the furnace isn't answering, and that points to the power side. Check that the switch on or near the furnace, the one that looks like a light switch, is on, and check the breaker. If those are fine, the igniter may have failed, or a safety switch is holding the furnace off because of a clogged filter or a blocked vent. A furnace won't run with a dirty filter restricting airflow, so that's worth checking before anything else. Past that, a contractor needs to test the parts to find which one is at fault.
- Why is my furnace blowing cold air?
- Give it a few minutes. A furnace runs the blower before the burners are fully up to temperature, so a short stretch of cool air at startup is normal. If it keeps blowing cold or never warms up, the burners aren't lighting, and that's usually the igniter or the flame sensor. A dirty flame sensor will make the furnace shut the burners off right after they light, which can feel like the furnace is just moving cold air around. Either way it needs a contractor to check the ignition system directly.
- Why won't my furnace pilot light stay lit?
- This is almost always the thermocouple, the small probe that sits in the pilot flame and tells the gas valve the pilot is lit. When it wears out or sits out of position, the gas valve shuts the pilot off as a safety measure, even though the flame was burning fine. A draft blowing out the pilot is possible too, so worth noting if it happens right after the furnace closet door opens or closes. A furnace with a standing pilot doesn't need power to keep that flame lit, which matters here given how often winter storms knock the power out, but a failing thermocouple isn't something to fix by relighting it over and over. It needs to be tested and likely replaced.
