Boise's winters are colder than most people outside Idaho expect. January lows regularly drop into the teens, and when a furnace fails overnight, pipes can freeze and interiors drop to dangerous temperatures within hours.
The most common furnace failures in Treasure Valley homes are igniter failures, cracked heat exchangers, failed blower motors, clogged flame sensors, and malfunctioning limit switches. Most of these are one-visit repairs when caught early. A cracked heat exchanger is the serious one — it can allow carbon monoxide to enter your living space and is not something to defer.

What furnace repair costs in Boise
Most furnace repairs in Boise fall in the $150–$800 range for parts and labor. An igniter replacement — one of the most common repairs — typically runs $150–$300 all-in. Blower motor replacement is higher, usually $350–$600. A cracked heat exchanger is the most expensive repair, sometimes $800–$1,500, which often makes full furnace replacement the better financial decision.
Gas furnaces last 15–20 years in Idaho's climate. If your furnace is over 12 years old and needs a major repair, your contractor will walk you through the economics of repair versus replacement. A new 80% AFUE gas furnace in Boise runs $2,500–$5,000 installed, depending on BTU requirements and equipment tier.
One practical note: if your furnace is older and the repair is minor, consider scheduling a full tune-up at the same appointment. Technicians can inspect the heat exchanger, clean the burners, check the flue, and verify CO detector function while they're already at your home — often for an additional $80–$150.
