Eight months of heat puts a lot of hours on your furnace
Chaska needs heat from October through May, eight months out of the year. That is a long stretch of the igniter and flame sensor lighting the burner over and over, and those are the parts that tend to wear out first. When one fails, the furnace either won't light or shuts off soon after it starts.
Most homes here heat with gas, and a furnace needs electricity to run its blower and controls even then. Carver County has seen 36 winter storms and 51 damaging wind events over the last ten years, and storms like that take down power lines. Statewide, 13% of Minnesota households were without power for at least 24 hours in 2024. With winter lows here averaging 9°F, a furnace that loses power or won't restart on its own becomes a problem fast.

A new furnace would cut about $120 a year off heating for a typical Carver 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.
There is no state record to check on a furnace repair contractor in Carver County. Minnesota does not test HVAC contractors and does not register them either, so there is no state list to look at before work starts. Whatever protection exists here has to come from somewhere other than a license.
A gas furnace depends on a sound connection at the gas line, and that is the part of the job with real consequences if it is done wrong. Minnesota's facts do not point to any state check on that connection for a repair like this one. In Carver County, where 75.4% of homes heat with gas, that is the detail worth knowing has no license standing behind it.

- Why won't my furnace turn on?
- Start with the thermostat. Check that it's set to heat and the temperature is above room temperature, and make sure it has power if it runs on batteries. If the thermostat looks fine, check the furnace switch, which looks like a light switch near the unit, and the breaker for it in your panel. A furnace that still won't respond after that likely has a failed igniter, a bad flame sensor, or a control board issue, and those need a contractor to diagnose.
- Why is my furnace blowing cold air?
- Most often this means the blower is running but the burners haven't lit. Check your air filter first, since a clogged one can cause the furnace to overheat and shut the burners off while the fan keeps blowing. If the filter is clean, the igniter or flame sensor may be failing to light the burners at all. A furnace can also blow cool air for the first minute of a cycle while it warms up, which is normal, but air that stays cold needs a contractor to look at the burner assembly.
- Why won't my furnace pilot light stay lit?
- This usually comes down to the thermocouple, the small sensor that tells the gas valve the pilot is actually burning. When it wears out or sits out of position, the valve shuts off gas to the pilot as a safety measure even though the flame was fine. A draft blowing out the pilot is another common cause, especially in a windy spot near a door or vent. Either way, this is a gas component and worth having a contractor check rather than repeatedly relighting it yourself.
