Nine months of heat, and nights that drop to 10 below
Red Wing needs a working furnace from September through May. On winter nights that average 10°F, the burner is cycling on and off for hours at a stretch to keep the house at temperature. Every one of those cycles puts a little more wear on the igniter and the flame sensor, and those parts tend to fail on the coldest nights, right when the furnace is working hardest.
Goodhue County has seen 35 winter storms and 52 damaging wind events over the past ten years. Storms like that knock out power, and across Minnesota, 13% of households lost power for 24 hours or more in 2024. A furnace with no power will not run no matter what shape it's in, and when the power comes back on, a furnace that was already struggling can fail to restart on its own.

A new furnace would cut about $120 a year off heating for a typical Goodhue 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.
Minnesota has no state license for HVAC contractors.
Minnesota does not license HVAC contractors, and it does not register them either. There is no state exam behind the person who comes to look at your furnace, and no state list with their name on it. Whoever shows up, the state has no record of them.
So nothing at the state level stands behind a furnace repair here. That matters most on the gas connection, since a bad seal or a bad joint is what makes a furnace dangerous rather than just not working, and in Goodhue County most homes heat with gas. Minnesota leaves that unchecked. There is no license, no registration, and no state inspection standing between a homeowner and whoever they hire.

- Why won't my furnace turn on?
- Most often the thermostat is asking for heat but the furnace isn't getting power or the signal to start. Check that the thermostat has power and is set to heat above room temperature, and check the breaker for the furnace. Some furnaces also have a switch on the unit itself, or nearby on the wall, that looks like a light switch. That switch gets bumped or turned off by accident more than people expect. If power and the thermostat both check out, the ignition system may be failing to start the burners, and that needs a contractor to look at.
- Why is my furnace blowing cold air?
- If air is moving but it's not warm, the blower is running without the burners lighting. That points to an ignition problem, a flame that won't sense, or a safety switch shutting the burners down before they get going. A dirty filter can also make a furnace run longer to reach temperature, which can feel like cold air blowing even when it's warming up slowly. With winter lows here averaging 10°F, a furnace that's only moving air and not heating needs attention the same day, not the same week.
- Why won't my furnace pilot light stay lit?
- This usually means the thermocouple, or the flame sensor on newer furnaces, isn't reading the flame as lit even though it is. That part's job is to confirm there's a flame before it lets gas keep flowing, and when it's dirty or failing it shuts the gas off. A draft blowing across the pilot can also blow it out, so check whether something nearby is pushing air toward it. If the pilot relights and goes out again on its own, the sensing part needs to be cleaned or replaced by a contractor.
