Blower motor replacement cost
Replacing the blower motor in a furnace or air handler costs $500 to $2,300. A standard PSC motor costs $500 to $1,400 installed, while a variable-speed ECM motor costs $800 to $2,300.
Quick answer
$500 – $2,300parts and labor
Most blower motor replacements cost $500 to $2,300. If the motor is under warranty, labor is about $200 to $400, and simple blower repairs start near $300.
Cost by motor type
| Motor type | Parts and labor |
|---|---|
| PSC (permanent split capacitor, single speed) | $500 – $1,400 |
| ECM (electronically commutated, variable speed) | $800 – $2,300 |
ECM motors are more efficient and quieter, but their electronic modules make replacements pricier. Some ECM failures only need a new module.
Cheaper fixes to check first
| Repair | Cost |
|---|---|
| Blower motor capacitor | $100 – $250 |
| Blower wheel (squirrel cage) | $100 – $400 |

| Labor under warranty | $200 – $400 |
Signs of a failing blower motor
- Weak or no airflow from vents while the outdoor unit runs
- Humming, squealing or grinding from the furnace
- Burning smell or the motor tripping its overload
- Higher energy bills and rooms that never get comfortable
Dirty filters and blower wheels are a leading cause of motor failure; regular maintenance helps.
How to get a fair quote
- Get at least three written quotes that list the brand, model number, size (tons or BTU) and efficiency rating.
- Ask whether the price includes permits, removal of the old unit, refrigerant, a new thermostat and any duct or electrical work.
- Ask for a load calculation (Manual J) instead of matching the old unit's size by default.
- Compare labor warranties (1 to 10 years) as well as the manufacturer's parts warranty, and register the equipment.
- Schedule non-urgent work in spring or fall, when contractors are less busy and more willing to discount.
