Nine months of heat, and nights near 8 below
Your furnace in Elk River works from September through May. That is nine months a year it has to run, and on winter nights that average 8°F it runs longer and starts more often to keep the house warm. Every start puts a load on the igniter and the flame sensor, and over enough winters one of them gives out. You will notice it as short cycling, a furnace that will not light, or one that lights and then shuts itself off.
Sherburne County has seen 23 winter storms and 27 damaging wind events over the past ten years. Storms like these knock out power, and in Minnesota 13% of households lost power for 24 hours or more in 2024. Most furnaces need electricity to run the blower and controls even if they burn gas, so a power outage in the middle of a cold snap means no heat until it comes back on.

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.
Minnesota has no state license for HVAC contractors.
There is no state license or registration to check here. Minnesota does not test HVAC contractors and does not keep a record of who does this kind of work, so a furnace repair leaves no state paperwork behind it. Some counties or cities set their own rules for the trade, but that is a local matter, not a state one, and it does not add up to any statewide credential.
Gas connections are the dangerous part of furnace work, since a bad one can leak, and Minnesota has no state inspector checking that on a repair call. In Sherburne County, where 71.7% of homes heat with gas, that connection is the piece of the job worth the most attention.

- Why won't my furnace turn on?
- Start with the thermostat. Check that it's set to heat and the temperature is set above room temperature, since a setting knocked off by accident is the most common reason nothing happens. If the thermostat looks right, check the furnace switch, usually a light switch on or near the unit, and the breaker for the furnace. Furnaces also stop and won't restart when the filter is clogged enough to trip a safety switch, or when the igniter has failed. A contractor can tell you which of these it is.
- Why is my furnace blowing cold air?
- Most of the time this means the blower is running but the burners aren't lighting. A furnace that only blows cold air often has a failed igniter or flame sensor, so it tries to start, fails, and just circulates room air through the ducts. It can also mean the thermostat fan setting is on rather than auto, which runs the blower nonstop whether or not the furnace is heating. If the air is cold and stays cold, don't wait on it. Nine months of the year here, from September through May, a furnace that won't heat needs a contractor's attention right away.
- Why won't my furnace pilot light stay lit?
- This usually comes down to the thermocouple, the small part that senses the pilot flame and keeps gas flowing to it. When it wears out or sits out of position, it reads the pilot as out even when it's lit, and shuts the gas off. A draft blowing across the pilot or a dirty pilot orifice can also put it out repeatedly. Note that a standing pilot itself doesn't use electricity, so power going out isn't the cause. A contractor can test the thermocouple and replace it if it's the problem.
