Common Furnace Questions from Hermantown Homeowners
Why is my furnace blowing cold air?
A dirty flame sensor is the most common cause we see in Hermantown. The sensor gets coated with residue and can’t detect the burner flame, so the furnace shuts off the gas as a safety measure. Clogged filters and faulty ignitors are also frequent culprits. We test each component to find the actual cause.
How often should a furnace be serviced?
At least once a year, ideally in the fall before heating season starts. Hermantown winters push furnaces to their limits, and a tune-up catches worn parts before they fail on the coldest night of the year. Check your filter monthly during heavy use.
Should I repair or replace my furnace?
If the furnace is over 15 years old and the repair bill is more than half the cost of a new unit, replacement usually wins. Many Hermantown homes built in the early 2000s are reaching that crossover point now. We’ll show you the math on both options.
How much does furnace repair cost?
It varies by the part and the labor involved. A flame sensor or ignitor is on the lower end; a blower motor or control board costs more. We quote a firm price before we start any work on your Hermantown furnace — no surprises.
