Seven months of heat, and the cold snaps that break things
Your furnace works from October through April here, seven months of the year. On winter nights averaging 29°F, it cycles on and off for hours at a stretch to hold the house steady. Each cycle means another ignition, and the igniter is usually the first part to wear out from all that starting and stopping.
Most homes in the area heat with electricity, so when the power goes out, the furnace stops no matter what shape it is in. Calvert County sees real winter weather, with 12 winter storms and 120 damaging wind events over the past ten years, and across Maryland about 1 in 10 households lost power for a full day or more in 2024. When the furnace won't restart after an outage, or it's running constantly but the house still feels cold, that's usually a sign something inside it needs attention.

Maryland requires HVAC contractors to hold a state license.
The Maryland Board of Heating, Ventilation, Air Conditioning, and Refrigeration Contractors tests and licenses HVAC contractors before they can take on jobs like this one. The license belongs to the contractor, not to any single job, so the same license that covers a furnace repair in Calvert County covers the next one somewhere else in the state.
For a furnace repair, that license is what stands behind the person working on your gas connections and burner assembly. A bad connection is the dangerous part of this job, and the state's testing is what gives you a record of who did the work and whether they were qualified to do it.

- Why won't my furnace turn on?
- The most common reason is the thermostat is not calling for heat, whether that's dead batteries, a tripped breaker, or a setting that got bumped. Check the breaker panel next, since a furnace on its own circuit can trip without affecting anything else in the house. If power and thermostat both check out, the igniter or the flame sensor may have failed, and that's a job for a licensed contractor to diagnose. With lows around 29°F overnight here, it's worth getting looked at quickly rather than waiting it out.
- Why is my furnace blowing cold air?
- Most of the time this means the blower is running but the burners haven't lit, so air is moving through the ducts without being heated. A dirty flame sensor or a failed igniter can cause this, and both are things a contractor checks during a repair visit. It can also mean the furnace is in the middle of its normal cycle, since a few seconds of cooler air before the burners fire is expected. If the air stays cold the whole time it runs, the furnace needs a look before the next cold night.
- Why won't my furnace pilot light stay lit?
- This usually points to a worn thermocouple, the part that senses the pilot flame and keeps the gas valve open. When it wears out, it shuts the gas off even though the pilot is lit, and the flame goes out. A draft blowing across the pilot or a dirty pilot orifice can also cause this. Either way, it's a gas appliance issue, and a licensed contractor should be the one to repair it rather than relighting it over and over.
