Two neighbors can have the same failed blower motor and receive quotes that sit hundred's of dollars apart. The gap rarely comes from the contractor.
Instead, it comes from the motor type inside the furnace and what else broke along with it. The fan motor, also called the blower motor, pushes heated air from your furnace through the ducts and out of your vents. When it fails, the burners may light, but little or no warm air reaches your rooms.
This guide shows where that money goes: how motor type, size, labor, and add-on parts build your quote, and how to decide between replacing the motor, or putting the money toward a new furnace.
The cost of furnace blower motor replacement typically falls between $300 and $900 including parts and labor. This table puts the common figures side by side.
| Cost item | Typical range |
| Total, parts and labor | $300–$900 |
| Labor | $150–$400 |
| High end, premium motor and difficult access | up to about $2,400 |
Note: The above range is an estimated and actual rates may vary.
Bare universal motors can sell online for $50 to $250, but a motor matched to your furnace costs more, especially an ECM, and contractors often quote one bundled price.
Four things move the bill: the motor type, the horsepower, the labor time, and whether anything else broke along with the motor. A basic single-speed motor in an easy-to-reach basement furnace sits at the bottom of the range. An ECM motor sold with its control module, in a furnace that has to be partly disassembled, sits at the top. That is why blower motor furnace replacement cost varies so much from one house to the next.
A dying blower motor rarely fails without warning. The usual signs are weak airflow from the vents, squealing, grinding, or rattling from the furnace cabinet, a burning smell, and a furnace that cycles on and off or shuts down on its high-limit switch. You may also notice the house heating unevenly or the fan running very slowly.
Do not run a struggling motor through the season. For example, without enough airflow the furnace overheats and trips its safety controls, and repeated overheating stresses other parts, which is how a small repair turns into a bigger one.
Our guide on the real cost of delaying HVAC repairs shows how that adds up. Blower motors commonly last 10 to 20 years, so a failure on an older furnace is also your cue to think about the bigger picture, which the third section covers.
First, make sure you are pricing the right motor. Your furnace has a blower motor that moves air through the ducts, and a separate inducer motor (sometimes called the draft or vent motor) that pulls combustion gases out of the furnace.
They are different parts with different prices. If the furnace tries to start but shuts down quickly, the inducer may be the culprit. If the burners light but air barely moves, suspect the blower.
| Feature | PSC motor | ECM motor |
| Typical part cost | $350–$800 | $600–$1,150 |
| Common in | Older and basic furnaces | Newer, higher-efficiency furnaces |
| Speed control | One or a few fixed speeds | Electronically controlled, variable |
| Electricity use | Higher | Noticeably lower |
| Common extra part | Run capacitor | Control module, sometimes sold with the motor |
The model label on the motor or the furnace's data plate will say which one you have. A technician can confirm before ordering anything.
Residential blower motors range from 1/4 to 1 horsepower, and the most common sizes are 1/4, 1/3, and 1/2. In general, cost climbs with horsepower while labor stays about the same. Angi's figures for the common sizes show the pattern.
| Motor size | Typical cost |
| 1/4 horsepower | $100–$550 |
| 1/3 horsepower | $100–$800 |
| 1/2 horsepower | $120–$1,000 |
| 3/4 horsepower | $175–$1,500 |
| 1 horsepower | $250–$2,000 |
Note: The above costs are estimates and actual costs may vary.
Furnace motor blower replacement cost also rises with speed capability: variable-speed motors run roughly $600 to $1,500 but use less electricity.
However, do not upsize on a whim. Match the original specification for horsepower, rotation, and mounting, because an oversized motor adds cost and can hurt airflow balance and efficiency.
Labor and the work takes about one and a half to three hours including diagnosis, wiring, and testing. Tight access adds time. A furnace in a main-floor closet is simpler than one buried in a crawl space or attic.

Your price is set by three things: the motor type, the labor time, and whether a second part failed with the motor.
Replacing the motor is worth it when the furnace is otherwise healthy. Yes, you can replace only the blower motor, and for most furnaces under about 12 to 15 years old with a sound heat exchanger, it is the sensible move. The cost of furnace motor replacement is a small fraction of the thousands shown in our furnace replacement cost guide, and a fresh motor can run for many more years.
Use the $5,000 rule. Multiply the repair quote by the furnace's age in years. If the result tops $5,000, replacement is the better spend. A 16-year-old furnace with a $700 motor quote scores $11,200, well past the line, while a 6-year-old furnace with the same quote scores $4,200 and is worth repairing.
Walk away from the repair when the furnace is near the end of its life and the motor is just one of several problems. On an old unit, money spent at the high end of this range is better put toward a new furnace.
| Replace the motor if | Consider a new furnace if |
| Furnace is under about 15 years old | Furnace is 15 to 20 years old or more |
| No other major repairs are needed | You have had repeated repairs in recent years |
| Heat exchanger is sound | A technician finds a cracked or failing heat exchanger |
| $5,000 rule score is under $5,000 | $5,000 rule score is over $5,000 |
| PSC motor, simple job | Efficiency is poor and bills keep rising |
Some steps are safe and can save a service call entirely. Before you spend anything, run through this list.
However, if none of that fixes it, call a technician.
A fair furnace fan motor replacement cost comes with clear answers. Ask these before you say yes.
Manufacturer warranties often only cover the part, so expect to pay for the visit even when the motor is covered. Finally, have your furnace model and serial number ready, and look up the install date.
A blower motor lasts longest when air moves freely. For example, a dirty blower wheel or blocked returns make the motor work harder and run hotter, so keep vents and returns clear and have the wheel and capacitor checked at your annual furnace tune-up.
After the repair, listen during the first week for rubbing, rattling, or squealing, and confirm that airflow feels steady at every vent. If a new motor sounds rough or the furnace short-cycles, call the installer back right away.

Most replacements take about 1.5 to 3 hours, including diagnosis, wiring, and testing. A hard-to-reach furnace or a second failed part can add time.
Blower motors commonly last 10 to 20 years. Clean airflow helps a motor reach the upper end of that range, and a failure on an older furnace often means the rest of the unit is aging too.
Only if it is damaged. The technician should clean the wheel during the job, since buildup unbalances it and strains the new motor. A cracked, bent, or heavily worn wheel is worth replacing at the same time, because the part costs roughly $25 to $300 and the furnace is already open.
