How Much Does Furnace Blower Motor Replacement Cost?
A residential furnace blower motor can cost anywhere from $70–$2,400 before installation. With labor, you’ll add $200–$400 to your total project cost. Here are the main factors when it comes to fan motor repair costs.
- Horsepower: The more powerful the motor, the more it will cost.
- Parts: If only certain parts of the motor are broken, you may be able to replace them individually.
- Labor cost: Even if your furnace is still under warranty, you’ll have to pay a motor installation cost.
- Brand: Though not a huge variation, some brands are pricier than others.
Cost by Motor Horsepower
Motor strength is measured in horsepower. Most residential furnaces only need a motor of between one-fourth and one-half horsepower, but larger homes may need up to 1 horsepower. In general, the more powerful the motor, the more it costs.
| Motor Horsepower | Unit Cost |
|---|---|
|
¼ |
$70–$500 |
|
⅓ |
$100–$800 |
|
½ |
$120–$1,000 |
|
¾ |
$175–$1,500 |
|
1 |
$250–$2,000 |
Cost of Parts
Your blower motor can sometimes be repaired by replacing some of its internal components rather than buying an entirely new one. These components vary widely in cost.

Labor Costs
In addition to buying a new blower motor or furnace parts, you’ll also pay an HVAC contractor to replace them. Heating, ventilation, and air conditioning (HVAC) repair contractors typically charge $75–$150 per hour, and sometimes a flat service fee for the visit. You can expect to pay $200–$400 in labor for blower motor repair and replacement. The process usually takes two to three hours and involves the technician inspecting the system, diagnosing the problem, removing the old motor, installing the new one, and testing the system.
Cost by Brand
Some furnace parts brands are more high-end than others, so the cost of your blower motor will partly depend on which you choose. Make sure that choosing a blower brand different from the furnace maker’s won’t void its warranty. Here are some of the best furnace brands and their replacement cost.
| Brand | Cost |
|---|---|
|
American Standard/Trane |
$175–$2,000 |
|
Asana/Goodman |

What Are Additional Furnace Blower Cost Considerations?
Several factors influence the total cost of replacing an HVAC blower motor.
System Accessibility
If your furnace is in a hard-to-reach location, such as a cramped crawl space or behind other appliances, expect higher labor costs. HVAC technicians typically charge by the hour, so the more time they spend accessing and servicing the unit, the higher your bill. Even if only a single part needs replacing, the difficulty of disassembling the motor can drive up costs.
Motor Type
The type of blower motor you install significantly impacts both upfront and long-term costs:
- Single-speed motors ($100–$500): The least expensive option, these motors run at a constant speed, making them the noisiest and least energy-efficient.
- Two-stage or multi-speed motors ($120–$700): These offer better efficiency and noise reduction by operating at multiple speeds.
- Variable-speed motors ($300–$1,100): The most energy-efficient option, these motors automatically adjust speed to maintain optimal airflow and comfort.
Blower motors also come in two styles: permanent split capacitor (PSC) motors and electronically commutated motors (ECMs). PSC motors are cheaper to install at $300–$1,100 but cost more to operate. ECMs, which became the industry standard in 2019, are more energy-efficient but come with a higher installation cost of $600–$1,500.
Warranty Coverage
If your HVAC system is still under warranty, you may only need to cover labor costs, which typically range from $200–$400. Most warranties cover blower motor parts but not installation. However, attempting a DIY repair could void your warranty, so it’s best to check the terms before proceeding.
Should You DIY vs. Professional Furnace Blower Motor Replacement?
Homeowners might be tempted to save on installation costs by installing new blower motors themselves, but this usually isn’t a do-it-yourself (DIY) job.
Professional Blower Motor Replacement
Hiring an HVAC company comes with extra labor costs, but HVAC technicians are trained, licensed professionals who have experience with many types of blower motors and HVAC units. They’ll be able to get the job done efficiently and correctly and will identify whether the whole motor needs replacing or if updating some of the internal components is a better option. Most HVAC pros also offer warranties or guarantees on their work.
DIY Blower Motor Replacement
If you have substantial knowledge of your heating systems’ inner workings, you might be able to change the blower motor yourself. However, there are some risks to this approach. For example, if your blower motor died because of a larger system issue, fixing the motor may not address the root problem. Furnaces and other HVAC systems are expensive, and you don’t want to shorten the lifespan of the system with improper repairs. Focus on other, more DIY-friendly home improvement jobs instead.
How To Save Money on Blower Motor Replacement
Even if you hire an HVAC professional, you can lower the overall cost of replacing a furnace blower motor with these smart strategies:
- Check your warranty coverage: Before paying out of pocket, review your HVAC warranty to see if the blower motor or its parts are covered. Some warranties also include labor, reducing your total costs. Some warranties might even cover the entire cost of a new furnace.
- Compare motor prices: If your warranty doesn’t cover the replacement, look for lower-cost brands of similar quality. You may be able to source the part yourself for less than what a contractor would charge.
- Consider long-term savings: While energy-efficient motors may have a higher initial cost, they often lower your monthly utility bills, making them a more cost-effective choice over time.
- Prepare the workspace: Clearing a direct path to your furnace ensures the technician can work efficiently, reducing labor time and costs.
- Schedule service before peak season: HVAC contractors are busiest—and often charge higher rates—during the winter months. Testing your furnace before cold weather arrives allows you to schedule repairs when demand is lower.
- Stay on top of maintenance: Routine HVAC maintenance, such as annual cleaning and furnace filter replacements, helps extend the lifespan of all components, including the blower motor. A well-maintained system is less likely to fail prematurely.
- Take advantage of rebates: Many utility companies and manufacturers offer rebates on energy-efficient blower motors, helping offset the upfront cost.
Our Conclusion
We recommend hiring a professional furnace repair technician to replace your blower motor. Although you’ll pay more in labor, the integrity of your furnace or air conditioner will be protected. We recommend getting quotes from at least three local HVAC companies before making your choice. Be wary of anyone who charges much more or much less than the competition, and check out review sites like Better Business Bureau to get a sense of their reputation.

FAQ About Furnace Blower Motor Replacement
How long does a blower motor last?
Your furnace’s blower motor should last 10–20 years, about as long as the furnace itself. Proper maintenance will help ensure that both the blower motor and furnace last as long as possible.
What does a furnace blower motor do?
A forced-air furnace heats air by burning fuel like natural gas or heating oil. The furnace’s blower motor powers the fan that pushes this heated air through a home’s ductwork, distributing it throughout the house.
How do I know if my furnace blower is bad?
Here are some signs that your furnace blower motor has failed.
- Airflow from the vents is weak or nonexistent.
- The furnace makes rattling, squealing, or screeching noises.
- The furnace begins to overheat and you smell a burning odor.
- Your furnace shuts down frequently, leading to higher energy bills.
What is the cost of a furnace blower motor?
A furnace blower motor costs $70–$2,000. With professional installation, the total cost will likely be $270–$2,400.
What’s the difference between an AC and a furnace blower motor?
Blower motors fulfill the same function in both air conditioners and furnaces: moving treated air through ductwork. Both are located indoors—in an AC’s air handler or a furnace’s heat exchanger—and both ensure that heating or cooling can happen throughout the house. If your furnace and AC are combined in a packaged unit, the same blower motor will work for both. Air conditioners also have a separate condenser fan motor to cool the evaporator coils off.
