Whats the average cost to replace a blower motor?

The typical total price to replace a residential blower motor ranges from about $350 to $1,800, depending on motor type and labor. In most homes, expect PSC (standard) motors to fall around $600–$1,200 installed, while ECM (high-efficiency) motors commonly run higher, roughly $1,000–$2,000.

What you can expect to pay

The ranges below cover common scenarios for furnaces and air handlers, including both parts and professional labor. Regional differences and job complexity can push these numbers higher or lower.

• PSC blower motor replacement (the standard, non-ECM motor): Installed cost typically $300–$800.


• ECM blower motor replacement (high-efficiency motor with electronic control): Installed cost typically $700–$1,700.


• Blower motor replacement as part of a larger upgrade or when accompanying a new blower assembly: Installed cost typically $1,000–$2,500.

Costs can rise if additional items are needed, such as a new capacitor, belt, pulley, control board, or wiring repairs. Some technicians also charge a diagnostic or service call fee, which may be reduced or waived if you proceed with the repair.

Factors that influence the price

The final bill depends on several key factors. Understanding them helps you compare quotes and avoid surprises.

• Motor type and efficiency: PSC motors are cheaper upfront, while ECM motors cost more but offer energy savings and longer life in some systems.


• Labor rates and location: Urban areas and after-hours service typically cost more.


• System accessibility and complexity: Tight spaces, multi-story installations, or systems with ductwork that needs modification can require more labor.


• Additional components and repairs: Capacitors, relays, belts, pulleys, or control boards may be needed and raise the total.


• Warranty coverage and age of equipment: Some manufacturers or service plans cover parts or labor for blower motor replacements; older units may have limited or no coverage.

Being aware of these factors helps homeowners obtain accurate, itemized estimates and plan accordingly.

ECM vs PSC: what to consider

ECM motors are more expensive to purchase and install, but they offer variable-speed operation, better efficiency, and smoother performance. If your furnace or air handler is older or has other failing components, a full diagnostic may be warranted to decide whether replacing just the motor or upgrading the entire unit makes more economic sense.

Tips for getting a fair price

To avoid overpaying, consider getting multiple quotes, asking for an itemized breakdown (parts vs. labor), confirming whether a service call fee is included, and checking whether the warranty covers labor. Also, inquire about potential energy savings from an ECM upgrade to weigh long-term value against upfront costs.

Summary

Replacing a blower motor is a common HVAC service with cost ranges that reflect motor type, labor, and system specifics. PSC motors typically cost less to replace, while ECM motors command higher prices but can offer energy efficiency benefits. Before committing to a replacement, compare multiple quotes, verify what’s included in each estimate, and consider whether a full system upgrade might be more cost-effective in the long run. A well-informed decision can minimize downtime and maximize comfort and efficiency in your home.

How much is a new blower motor for AC?

The price for an AC blower motor varies significantly, but the average total cost for replacement is between $300 and $900. Factors like motor type (single-speed, variable-speed), part cost, and labor expenses influence the final price, with some jobs costing over $1,400. A car AC blower motor, for example, can cost much less than a home HVAC system, sometimes under $50 for the part alone.
 
Factors that influence the price

• Motor type: Variable-speed motors are the most expensive, while single-speed motors are generally the cheapest. 
• Labor costs: Labor is a significant part of the total price and can increase the cost substantially, especially for difficult-to-access motors. 
• Part cost: The price of the motor itself varies depending on the brand, size, and type. 
• Warranty: If your motor is still under warranty, the replacement cost may be significantly lower, possibly just covering labor costs. 
• System and location: The complexity of your HVAC system and your geographic location can affect labor rates. 

Typical costs

• Average replacement: $300 to $900, with an average of $560. 
• Single-speed motor: $300 to $700. 
• Variable-speed motor: $500 to $1,400+. 
• Car blower motor: Parts can sometimes be found for under $50, but installation costs will add to the total. 

How to get an accurate price

• Contact a professional: Get quotes from several local HVAC or auto repair companies for an accurate estimate based on your specific needs.
• Check your warranty: See if your HVAC system or vehicle's warranty covers the cost of the replacement part and/or labor. 

How much should a mechanic charge to replace a blower motor?

Average Cost:
A blower motor replacement can cost between $150 and $2,000 depending on the size of the motor, single or variable speed, accessibility and difficulty of installation, and contractor labor rates.

Can I replace a blower motor myself?

Yes, a mechanically skilled individual can replace a blower motor, but it is generally not recommended for beginners due to safety risks like electrocution and the potential for incorrect installation that can lead to reduced efficiency or system damage. If you decide to proceed, you must ensure the new motor has the exact same horsepower, amperage, and RPM as the old one.

• Safety hazards: Handling electrical components without experience can lead to electrocution or other dangers. 
• Incorrect installation: Improper installation can cause the new motor to run inefficiently, shorten its lifespan, or even damage other parts of your HVAC system. 
• System damage: A faulty blower motor can overwork other components, leading to more extensive and expensive repairs down the line. 

If you choose to replace it yourself

• Ensure compatibility: The new motor must have the same specifications as the old one, including horsepower, amperage, and RPM. 
• Gather tools: You will need tools such as a flat-bladed screwdriver, vise grips, needle-nose pliers, a socket set, and the new blower motor. 
• Follow professional advice: If you find a detailed guide, like one from Packard Online, it's important to follow it step-by-step, and always shut off the power at the breaker first. 

How long does it take to replace a HVAC blower motor?

two to three hours
An average blower motor replacement might take anywhere from two to three hours of time. Keeping in mind the cost per hour and time taken to replace an old motor in an HVAC unit can give you a better handle on your next HVAC maintenance project.
