Common Furnace Problems in Boise Homes
Boise winters regularly drop below freezing. That heavy demand causes specific furnace issues we see every year:
• Furnace not turning on
Often caused by a failed ignitor, thermostat issue, tripped safety switch, or electrical fault.
• Furnace blowing cold air
Could be a flame sensor issue, gas supply problem, or overheating safety shutdown.
• Furnace short cycling
Dirty filters, airflow restrictions, or overheating heat exchangers are common causes.
• Loud banging or rattling
Ignition delay, loose components, or duct expansion can cause loud startup noises.
• Burning smell from vents
Sometimes normal at season start — but persistent smells require immediate inspection.
If your furnace is showing any of these signs, it’s best to schedule a professional furnace inspection before the problem worsens.
