Furnace Repair in Montana: what's different
Furnace Repair across Montana depends on the climate (IECC climate zones 5–6). Heating is the main load in cold climates. Furnaces and boilers run for months, so ignition, venting, heat exchanger and carbon monoxide checks before winter are important.
In Montana specifically: extreme cold. Furnace failures in subzero weather can freeze pipes quickly.
Montana does not have a statewide HVAC license, though contractors with employees must register with the Department of Labor and Industry. Local jurisdictions may issue permits. Ask any contractor for their license number before work starts, and expect a written price for furnace Repair.
Common systems in Montana: Gas furnaces, Boilers, Propane heat, HRV ventilation. Tell the contractor which one you have so they bring the right parts.

Why does my furnace turn on then off right away?+
The most common reason is a dirty flame sensor, which can't prove the flame so the board shuts the gas off. Other causes are a weak pressure switch or a blocked vent.
Is a cracked heat exchanger dangerous?+
It can be, because it may let combustion gases mix with house air. A tech will usually shut the furnace off and red-tag it until it is repaired or replaced.
