In Dillon, the furnace runs all year and rarely gets a break
Your furnace works every month here, with winter nights averaging 12 degrees from December through February. It cycles on and off through the night to hold the house against that cold, and each start puts wear on the igniter and the flame sensor. Those are the parts that tend to fail first, and when one does, the house goes cold fast.
Summer afternoons average 71 degrees, mild enough that cooling asks little of the system, so the furnace gets almost no rest before winter starts again. This area has seen 71 winter storms and 83 damaging wind events over the past ten years, and storms like that knock out power. In 2024, 18% of Montana households went at least 24 hours without it. A furnace that loses power on one of those nights stays off until the power is back, and most start up again on their own once it is.

Montana requires HVAC contractors to hold a state license.
The license is held by the contractor, not tied to any single job. It covers the person or company doing the work, and the Department of Labor and Industry keeps that record on the state level.
Work under $2,500 in Montana does not need a licensed contractor. A heating and cooling repair can land on either side of that line depending on what the job turns out to be, so whether the license applies here depends on the scope of the work once someone looks at the system.

- Why is my heat not working?
- Start with the thermostat and the power to the furnace. If the thermostat screen is blank, check the breaker and any switch that looks like a light switch near the unit, since that switch cuts power to the furnace. If power is fine, listen for the furnace trying to start. A furnace that clicks a few times then stops is usually failing to light, often the igniter or the flame sensor. With nights here averaging 12°F in the winter, a furnace that will not hold heat needs attention right away, since a home can drop to a dangerous temperature fast at that kind of cold.
- Why is my system running but not cooling the house?
- Check the air filter first. A filter clogged with dust blocks airflow across the coil, and the system will run without bringing the temperature down. If the filter is clean, look at the outdoor unit and make sure nothing is blocking it, no leaves or grass packed against the fins. If the air coming from the vents is warm rather than just weak, the system likely has a refrigerant leak or a failing part, and that needs a contractor to diagnose.
- What can I check before calling for HVAC repair?
- Check the thermostat batteries and settings, the breaker for the system, and the air filter. These catch a lot of no-heat and no-cool calls on their own. If the system has a switch near it that looks like a light switch, make sure it has not been bumped off. Beyond that, a contractor will need to look at the actual equipment and price the job for the specific house, and Montana requires that contractor to hold a state license.
