How much does it cost to replace a furnace blower motor?

Replacing a furnace blower motor costs $500 to $2,300 according to HomeGuide, with the motor type driving most of that spread.

The wide band is the honest one here, because two very different parts share a name. HomeGuide splits it by motor type: a permanent split capacitor motor runs $500 to $1,400 installed, and an electronically commutated motor runs $800 to $2,300. Angi's average of $560 sits at the PSC end, with a range of $300 to $900 and a ceiling of $2,400 for large or hard-to-reach motors.

HVAC blower motor replacement cost is the same question

People search this both ways and it is one part. HomeGuide says so directly: in a combination heating and cooling system, the air conditioner and the furnace may use the same blower motor to move cooled or heated air. In a furnace it sits in the base of the unit; in a central air system it sits inside the indoor air handler. Same motor, same job, same price.

The difference is not just price. HomeGuide says an ECM motor has built-in electronics that adjust speed and torque to the demand, and that ECM motors use up to 75% less electricity than PSC motors. It also warns that you cannot simply upgrade from a single-speed motor to a variable-speed one — the replacement has to match the original speed, and changing that means replacing the full system.

Cost to replace a furnace blower motor: what drives your number

Access, mostly. HomeGuide says blower motors often have several parts in front of them that have to come out and go back in, and that labor costs rise when the furnace or air handler sits somewhere awkward like a tight attic. It prices technician labor at $75 to $150 an hour and a diagnostic service call at $75 to $200, with some companies crediting that fee against the repair.

Size matters too, in a way that is easy to miss. HomeGuide says a larger system needs a higher-horsepower motor and those cost more. Angi's own table runs from $100 to $550 for a quarter-horsepower motor up to $120 to $1,000 for a half-horsepower one.

Sometimes it is not the motor at all. HomeGuide prices a blower wheel — the squirrel cage the motor spins — at $100 to $400 installed, or $25 to $200 for the part alone, and says dirt buildup from skipped maintenance is a common cause of wheel failure. Ask which one failed before you pay for the more expensive answer.

The outdoor fan motor is a different part

Worth knowing before you compare two quotes that both say fan motor. The condenser fan motor lives in the outdoor unit and blows heat off the coil; the blower lives indoors and moves air through the house. HomeGuide prices the outdoor one separately at $200 to $700 with a national average of $450, and the part alone at $100 to $400.

If the quote says fan motor without saying which one, ask. They are hundreds of dollars apart.

How long a blower motor lasts, and how long the job takes

HomeGuide says an HVAC blower motor lasts 10 to 20 years with regular maintenance, and that replacing one takes 2 to 3 hours on average because the motor is usually tucked behind other components and wiring. Angi notes that an active warranty may leave you paying around $150 for the labor alone.

Questions people ask next

How much does an AC blower motor replacement cost?
The same as a furnace one, because it is usually the same part. HomeGuide publishes $500 to $2,300 across both motor types and says a combined heating and cooling system may use one blower motor for both jobs.
Is a PSC or an ECM motor on my furnace?
HomeGuide's rule of thumb is that furnaces older than about six years typically have a PSC motor and most furnaces manufactured today have an ECM. The technician can tell you from the data plate, and it changes the quote by hundreds of dollars.
How long does a blower motor replacement take?
HomeGuide says 2 to 3 hours on average. The technician removes whatever sits in front of the motor, swaps it, cleans the fan, tests the new motor and puts the furnace back together.
Can I replace a blower motor myself?
HomeGuide says replacing a blower motor yourself can void your HVAC warranty. That is the cost worth weighing before the labor saving, especially on a system still inside its manufacturer coverage.
