Central air and heater blower motor price factors

The following factors affect the cost to replace a blower motor:

  • Motor size and performance – Blower motors with higher horsepower (HP) cost more than lower HP models.
  • Motor type and speed – Single-speed or multi-speed PSC motors cost less than variable-speed ECM motors, but single-speed motors are less efficient and cost more to run.
  • Brand vs. generic – Branded or OEM blower motors typically cost more than generic or universal motors.
  • Installation labor – Replacing a blower motor DIY saves $200 to $400 in labor charges.
  • Accessibility – Blower motors often have one or several parts in front of them requiring disassembly and reassembly, which adds labor time.
  • Warranty – The manufacturer's warranty may cover the motor itself, but most warranties do not cover labor costs.
  • Additional parts required – Other related components like the capacitor or blower wheel may need replacing at the same time.

Blower motor installation cost

Blower motor installation costs $200 to $400 on average for labor alone. HVAC contractors charge $75 to $150 per hour with a minimum trip charge of $75 to $200. Installing a blower motor typically takes 2 to 3 hours, depending on its accessibility.

Labor cost to install blower motor
Factor Average cost
Blower motor part $100 – $500
Labor $200 – $400
Total installation cost $300 – $900

PSC vs. ECM blower motor replacement cost

Replacing a permanent split capacitor (PSC) blower motor costs $300 to $1,100 with installation. An electronically commutated (ECM) blower motor replacement costs $600 to $1,500.

PSC vs. ECM blower motor replacement cost
Motor type Average cost to replace
Permanent split capacitor (PSC) $300 – $1,100
Electronically commutated (ECM) $600 – $1,500
  • A PSC blower motor has 1 to 3 speeds and costs less upfront, but the low efficiency translates to higher operating costs. Furnaces older than 5 years typically have a PSC blower motor.
  • An ECM motor has variable speed and uses up to 75% less electricity than a PSC motor. ECM motors are the new standard mandated by the U.S. Department of Energy in 2019.

Single vs. variable-speed blower motor cost

Blower motor prices are $100 to $1,100 on average for the part alone, depending on whether the motor is single-stage, two-stage, or variable-speed.

Single vs. variable-speed blower motor cost
Motor type Motor unit price Total replacement cost
Single-stage $100 – $500 $300 – $900
Two-stage $120 – $700 $320 – $1,100
Variable speed $400 – $1,100 $600 – $1,500
  • Single-stage or single-speed motors operate on "high" or "off". Single-speed motors are the least efficient and the costliest to run.
  • Two-stage motors have 1 to 3 speeds. Multiple-speed blower motors are quieter than single-speed units because they are not constantly running at full capacity.
  • Variable-speed blower motors ramp up slowly and run at the lowest possible speed to maintain the home's temperature. Variable-speed motors cost more but reduce electricity costs and provide the best airflow control.

Blower motor repair cost

AC blower motor repair costs $150 to $700 on average, depending on the problem and whether the part is under warranty.

Consider the motor's age, efficiency, and frequency of repairs when deciding whether to repair or replace it. Replacing the blower motor is recommended if the repairs cost 50% or more of the replacement cost.

Blower motor repair parts cost
Part Average price*
Bearing $20 – $200
Belt $5 – $25
Blower resistor $25 – $55
Blower wheel (squirrel cage) $25 – $300
Capacitor $10 – $50
ECM motor control module $220 – $800
ECM repair kit $20 – $60
Housing $90 – $300
Pulley $30 – $250
Shaft $30 – $300

*Not including installation.

Blower wheel replacement cost

HVAC blower wheel replacement costs $100 to $750 including labor or $25 to $300 for the part alone. Blower wheels typically need replacing if the furnace is still noisy after tightening or replacing the screws. Dirt buildup from lack of routine maintenance is a common cause of blower wheel failure.

Blower capacitor replacement cost

A furnace blower capacitor costs $100 to $250 with installation or $10 to $50 for the part alone. A humming or buzzing motor often indicates a bad capacitor rather than a broken blower motor.

Frequently asked questions

What is a blower motor?

The blower motor is the part of the air handler or furnace that blows conditioned air through the ductwork to distribute it throughout the home. The AC and furnace typically use the same blower motor to move cooled or heated air.

How long does it take to replace a blower motor?

Replacing a blower motor takes 2 to 3 hours on average. The blower motor is typically located behind a control board and other furnace parts. An HVAC technician removes other components as needed, replaces the motor, cleans the fan, tests the new motor, and reassembles the furnace.

How long do blower motors last?

An HVAC blower motor typically lasts 10 to 20 years, depending on its usage.

How to test if a blower motor is bad?

Testing a blower motor requires electrical knowledge and a multi-meter to test the capacitor and electrical windings. Follow these troubleshooting steps before hiring an HVAC technician to test the motor:

  1. Confirm the circuit breaker on the home's electrical panel has not tripped.
  2. Confirm the on/off switch on the furnace's exterior is "on."
  3. Check the air filter for dirt buildup and replace it if needed.
  4. If the system turns on but not the blower, turn the power off and remove the furnace cover to expose the components.
  5. Clear any dirt and debris on and around the blower motor.
  6. Turn the power back on.
  7. Call an HVAC expert if the blower motor issue persists.

Where is the blower located in the AC unit?

The blower motor is located inside the furnace or air handler. The air handler is the indoor part of an HVAC system.
