Eight months of winter wears a furnace down
Hopatcong needs heat from October through May. That is eight months of the year your furnace has to work, on nights that average 20 degrees. Nearly half the homes here heat with fuel oil. An oil furnace depends on a clean nozzle and a good igniter to light, and either one can wear out or foul over years of hard use.
Sussex County has had 24 winter storms and 160 damaging wind events over the past ten years. Across New Jersey, 11 percent of households lost power for a full day or more in 2024. A furnace stops the moment the power does, and on a cold night that means a house losing heat fast, whether the problem is the storm outside or the furnace itself.

New Jersey requires HVAC contractors to hold a state license.
The license comes from the State Board of Examiners of Heating, Ventilating, Air Conditioning and Refrigeration Contractors, and it belongs to the contractor, not to any single job. The state tested that contractor and keeps a record of them before they ever touch your furnace. Because the license comes from the state, no town in Sussex County can require its own HVAC license on top of it.
For a furnace repair, that state license is what stands behind the person working on your gas connections and burner. A bad connection is the part of this job that can hurt someone, and in New Jersey it is the contractor's state license, not a local one, that is tied to their record of doing that work correctly.

- Why won't my furnace turn on?
- The most common reason is a thermostat setting or a power problem, so check those first. Make sure the thermostat is set to heat and the temperature is above room temperature. Look at the furnace switch, which looks like a light switch near the unit, and check the breaker too. If the furnace still won't respond, a bad igniter, a failed control board, or a safety switch that has tripped could be blocking it, and a contractor can test each one to find which.
- Why is my furnace blowing cold air?
- Usually this means the blower is running but the burners aren't lighting. A dirty flame sensor, a clogged filter, or a gas supply issue can all stop ignition while the fan keeps pushing air through the vents. 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 coming through, especially with 20°F nights common here from December through February, don't wait to have it looked at.
- Why won't my furnace pilot light stay lit?
- A pilot light that won't stay lit is almost always a thermocouple problem. The thermocouple is a small sensor that tells the gas valve the pilot is burning, and once it wears out or sits out of position, the valve shuts the gas off as a safety measure. A draft blowing across the pilot or a dirty pilot orifice can cause the same thing. Since a furnace with a standing pilot doesn't need power to keep the flame lit, this issue is about the flame and sensor, not electricity, and a contractor can tell which part is failing.
