Furnace inducer motor cost
By the HeatAndAirCost editors · Last updated September 3, 2026 · How we research prices
Short answer
A furnace inducer motor replacement costs $400 to $1,100, part and labor, in 2026[1]. The draft inducer sits in the middle of the furnace repair scale: more than a flame sensor or pressure switch, less than a heat exchanger. A weak inducer often shows up first as a pressure-switch lockout, because the switch depends on the draft it creates.
What moves the price
- Motor brand and match. Some brands run more than generic replacements, and the part must match the furnace[1].
- Assembly vs motor only. Replacing the whole inducer assembly costs more than the motor alone.
- Diagnostic fee. A standalone visit adds $75 to $200 if it is billed separately[2].
- Warranty status. A part still covered cuts the bill to labor only.
What the inducer does, and how it fails
The draft inducer is a small fan that runs before the burners light. It pulls combustion gases through the heat exchanger and pushes them out the flue, clearing the last cycle's exhaust and building the draft the pressure switch watches for. When the motor bearings wear, you hear it: a loud hum, a rattle, or a rising whine at startup. As it weakens, the pressure switch stops seeing enough draft and locks the furnace out, so a bad inducer and a pressure-switch fault often travel together.
Worth it or not
On a newer furnace, an inducer is a clear repair. On an older one, check the $5,000 rule before committing. Our furnace not turning on guide covers the lockout symptoms, and furnace repair cost shows where this sits among the common repairs.

Inducer motor FAQs
How much does a furnace inducer motor cost?
A furnace inducer motor replacement costs $400 to $1,100 for the part and labor. The draft inducer is a mid-range furnace repair: pricier than a flame sensor or pressure switch, cheaper than a heat exchanger or a full blower motor.
What does a furnace inducer motor do?
The inducer motor, also called the draft inducer, is a small fan that pulls combustion gases through the heat exchanger and pushes them out the flue before the burners fire. It clears the previous cycle's exhaust and establishes the draft the pressure switch checks for. Without it, the furnace will not safely light.
What are the signs of a bad inducer motor?
Listen at startup. A failing inducer often makes a loud humming, rattling, or high-pitched whine, or it may run slowly or not at all. Because the pressure switch depends on the inducer's draft, a weak inducer frequently shows up first as a furnace that locks out on a pressure-switch fault. The furnace clicks, tries to start, and shuts down.
Is a furnace inducer motor worth replacing?
On a furnace under about 12 years old, yes, a $400 to $1,100 inducer is usually worth it. On an older unit, run the $5,000 rule first. If the same furnace has already needed other repairs this season, the inducer may be the point where replacement makes more sense than another part.
