Blower Motor Replacement Cost

The blower motor pushes heated or cooled air through the ducts. The same blower serves both the furnace and the AC, so Angi notes there is no difference between a "furnace" and an "AC" blower motor. Angi puts the average replacement at $560, with high-end jobs up to $2,400. HomeGuide's range is $500 to $2,300.

Cost by motor type

HomeGuide says ECM replacements cost more because of the higher part price.

Cost by speed

Cost by horsepower

Labor and warranty

Manufacturer warranties usually cover the motor but not the labor.

Repair instead of replace

Angi puts blower motor repairs at $150 to $1,500. HomeGuide lists a blower wheel replacement at $100 to $400 including labor.

Signs of a failing blower motor

• Weak or no airflow from the vents while the furnace or AC runs.
• Humming, squealing or grinding from the indoor unit.
• The blower runs constantly or not at all.
• The furnace overheats and shuts off on its limit switch.

Replace the motor or the system?

Angi says a full replacement can cost upward of $2,000 including labor. On an older system, especially with an ECM motor, compare that against furnace replacement cost or HVAC replacement cost.

What the blower motor does

The blower motor in the furnace or air handler pushes air across the coil or heat exchanger and through the ducts. If it fails, the system may run but no air comes out of the vents.

More on signs of a failing blower motor

• Weak or no airflow from vents.
• Humming, squealing or grinding from the indoor unit.
• The motor runs hot or trips the system's safety limits.
• The blower runs only on certain speeds.

PSC vs. ECM motors

• PSC (permanent split capacitor) motors are the older, simpler type. They are less expensive to replace and run on a capacitor that can fail on its own.
• ECM (electronically commutated) motors are variable-speed and more efficient. They cost more to replace but use less electricity and provide quieter, more even airflow.

Check the simpler parts first

A bad capacitor, a failed control board relay or a wiring problem can make a good motor appear dead. A technician should test these before replacing the motor.

What affects the price

• Motor type and horsepower.
• Brand-specific OEM motors vs. universal replacements.
• Access to the blower compartment.
• Whether the blower wheel needs cleaning or replacement.

Questions to ask

1. Is it the motor, or the capacitor or control board?
2. Is the replacement an OEM part or a universal motor?
3. Is the motor covered under the system's parts warranty?

In Texas

Blower motors in Texas run long hours in summer, often in hot attics. A clogged filter makes the motor work harder and run hotter, so regular filter changes help it last.

What happens during a blower motor replacement

The technician turns off power to the furnace or air handler and removes the access panels. The blower assembly is usually removed as a unit by sliding it out of the cabinet. The motor is unbolted from the blower housing, the wires are disconnected, and the motor shaft is separated from the blower wheel. The new motor is mounted, the wheel is reattached and aligned, and the assembly is reinstalled. The motor is wired to the control board and the capacitor if it uses one, and the system is tested at each fan speed.

While the blower is out, the technician can clean the blower wheel. A dirty wheel reduces airflow and makes the motor work harder.

ECM motors and variable airflow

Many modern systems use ECM motors, which adjust their speed based on the system's needs. They are more efficient than older PSC motors and can improve comfort, but they cost more to replace. Some ECM motors have a separate electronic module that can fail independently of the motor itself. Replacing only the module can be cheaper than replacing the whole motor.

Upgrading from PSC to ECM

When an older PSC motor fails, some technicians offer a replacement ECM motor designed to fit older systems. It can lower electricity use and improve airflow, but it costs more up front. Ask whether the upgrade makes sense for your system's age.

Preventing blower motor failure

Change the air filter regularly. A clogged filter forces the blower to work harder, which can shorten its life. Keeping the blower wheel clean and making sure all supply and return vents are open also help.

Signs the blower is not the only problem

If a new blower motor fails again within a short time, look for the cause. A clogged filter, closed or blocked vents, undersized return ducts or a dirty evaporator coil all force the blower to work against high resistance, which makes it run hot. A technician can measure the static pressure in the duct system to see whether airflow is restricted. Fixing that problem protects the new motor, lowers energy use and often improves comfort in rooms that never got enough air.

How long the job takes

Most blower motor replacements take one to three hours, depending on how easy the blower assembly is to remove and whether the part is on the truck. Some ECM motors must be ordered and programmed for the specific furnace or air handler, which can mean a second visit.

Warranty on the motor

Ask whether the new motor carries a manufacturer warranty and how long the labor is guaranteed.
