Seven months of work in Glassboro cold
Your furnace runs from October through April here, and on winter nights that average 28°F it is not idling, it is working. Every time the burner lights, something has to strike that spark or heat that coil hot enough to catch the gas. Do that thousands of times over seven months and the igniter is usually the first thing to give out. You will notice it as a furnace that tries to start, clicks, and never quite lights.
Gloucester County has seen 15 winter storms and 140 damaging wind events over the past ten years, and power does not always hold through them. Statewide, 11% of households lost power for a day or more in 2024. A furnace with no power will not run no matter how sound the rest of it is, and when the power comes back on, most systems restart on their own. If yours does not, the problem is worth a call.

A new furnace would cut about $140 a year off heating for a typical Gloucester County home.

Repair makes sense when one part has failed and the heat exchanger is sound.
Replacement makes sense when the heat exchanger is cracked or the furnace keeps needing parts.
New Jersey requires HVAC contractors to hold a state license.
The license comes from the state board that oversees HVACR contractors, and it covers the contractor, not the individual job. It's the same license whichever town or city the work is in, since New Jersey does not let towns add their own license on top of it.
For a furnace repair, that state license is what stands behind the person working on your burner and gas line. Gas is the part of this job that has to be done right, since a bad connection is what makes it dangerous, and in New Jersey that work falls under the same contractor license, not a separate local sign-off. Most homes in Gloucester County heat with gas, so this is the rule covering the contractor coming into your house.

- Why won't my furnace turn on?
- Most likely the thermostat isn't calling for heat, or the furnace isn't getting power. Check that the thermostat is set to heat and the temperature is above room temperature, and check the breaker and the furnace switch, which looks like a light switch near the unit. If those are fine, the igniter may have failed, or a safety switch has shut the furnace down because of a clogged filter or a blocked vent. A furnace won't run with a dirty filter for long before it protects itself by shutting off, so check that first.
- Why is my furnace blowing cold air?
- If air is moving but it's not warm, the furnace may be stuck in fan mode, or the burners aren't lighting even though the blower is running. Check the thermostat is set to heat, not just fan. If it is, and you still get cold air, the igniter or the flame sensor is probably the problem, since either one failing stops the burners from lighting while the blower keeps pushing air through the ducts. A furnace that short-cycles, coming on for a minute and shutting off, points the same direction.
- Why won't my furnace pilot light stay lit?
- A pilot that won't stay lit is almost always the thermocouple, the small sensor that tells the gas valve the flame is burning. When it wears out or sits out of position, it reads no flame even when there is one, and the valve shuts the gas off. A draft blowing across the pilot can also cause this. Homes here run the furnace from October through April, so a pilot that keeps going out during that stretch is worth having looked at rather than relit over and over.
