Nine months of heat, nights near zero
Your furnace runs from September through May here, nine months of the year. On winter nights averaging 5 below zero, it is not cycling on and off so much as running long stretches just to hold the house at temperature. That kind of steady demand wears on the igniter and the blower motor, the parts doing the work hour after hour.
Ward County has seen 27 winter storms and 51 damaging wind events over the past ten years, and across North Dakota, 7% of households lost power for at least 24 hours in 2024. A furnace that was already struggling can fail outright when the power cuts and comes back, or when a storm pushes it past what it had left to give.

A new furnace would cut about $120 a year off heating for a typical Ward 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.
North Dakota requires HVAC contractors to hold a state license.
The state tests and records the contractor, not the job. Once someone holds that license, it stays on file with the Secretary of State and covers the work they do across North Dakota, not a single furnace or a single address. In North Dakota, work under $4,000 does not need a licensed contractor, so a small repair can fall outside that requirement depending on what it costs.
A furnace repair is gas work, and the license is what stands behind whoever is connecting or adjusting a gas line in your home. In Ward County, 56.7% of homes heat with gas, so that connection is the part of the job worth getting right. Where the job falls under the state's threshold, the license requirement itself may not apply, and the facts here do not name another inspection that steps in for that kind of repair.

- Why won't my furnace turn on?
- The most common reason is a thermostat set wrong or a breaker or switch that got flipped off. Check the thermostat is set to heat and above room temperature, then check the breaker panel and the switch on the furnace itself, which looks like a light switch nearby or on 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. Winter nights here average 5°F, so if it still won't start, get a contractor out rather than waiting on it.
- Why is my furnace blowing cold air?
- Air blows before it heats. When a furnace first starts, the fan often runs for a short time before the burners have warmed the air moving through it, so a few seconds of cool air is normal. If cold air keeps coming the whole time it runs, the igniter or the gas valve may not be lighting the burners at all, or the flame sensor is shutting the burners off right after they start. A dirty filter can also starve the burners of the airflow they need to stay lit. Either way, a furnace that never warms up needs a contractor to look at the burner assembly.
- Why won't my furnace pilot light stay lit?
- This almost always means the flame sensor or thermocouple isn't sensing the flame, so the gas valve shuts back off. Some of this is dirt built up on the sensor, which blocks it from reading the flame correctly. Some of it is a weak pilot flame that isn't touching the sensor at all, often from a draft or a clogged pilot orifice. A contractor can tell you whether the part needs cleaning or replacing.
