$300-$900: that’s the average HVAC blower motor replacement cost for 2025. But, there’s a catch.
A blower motor replacement costs as little as $300, but as much as $1,500 depending on the size and type of the motor. You’ll want to know the factors of why the cost fluctuation occurs.
Why?
Simply put: not knowing all the factors involved in an HVAC blower motor replacement cost can cost you more than if you were well-informed. The last thing you want is to fork out more dough than what you had in your budget.

Factors affecting the cost of an HVAC blower motor replacement
When it comes to replacing an HVAC blower motor, the total cost depends on two main factors: whether the unit is replaced or just certain parts. Otherwise, the following factors make up the bulk of the dollar signs on your final blower motor replacement bill.
- The size of the HVAC blower motor
- The type and speed of the HVAC blower motor
- Labor costs associated with replacing an HVAC blower motor
The size of the HVAC blower motor
It’s one of the most significant cost factors. Measured in horsepower (HP), the size of the HVAC blower motor ranges from one quarter to one horsepower.
As such, the average cost will increase as horsepower increases. Labor remains roughly the same.
Some of the most common residential motor sizes include ¼, ⅓, and ½. Of course, higher horsepower motors have more power to push air through the HVAC system. Higher HP motor blowers also tend to be quieter.
Pro tip: be mindful of the size of the HVAC motor in your home, as a motor that’s much larger than what a home needs can increase costs.
Here are some of the most common blower motor sizes by cost.
| Blower motor size | Average cost of each size |
| ¼ horsepower motors | $100-$550 |
| ⅓ horsepower motors | $100-$800 |
| ½ horsepower motors | $120-$1,000 |
| ¾ horsepower motors | $175-$1,500 |
| 1 horsepower motors | $250-$2,000 |
Type and speed of the HVAC blower motor
Furnace blower motors come in different shapes and sizes. As such, prices are different depending on the furnace blower motor. For example, a single-stage permanent split capacitor (PSC) motor comes at a lower cost than a two-stage or variable-speed electronically commutated motor (ECM).
Picking the right fan motor for your AC or furnace blower is a matter of determining which is most important to you: efficiency and costs.
But this dilemma leads us to labor costs, the topic of our next section.
Labor costs to replace an HVAC blower motor
The cost to replace a furnace or blower motor typically ranges anywhere between $150 and $250, with most of the costs coming from labor.
Part of the range includes questions such as how accessible — and involved — the HVAC labor is. For example, if your HVAC system is buried deep in the crevices of your attic, or if your HVAC repair pro has to take apart your entire furnace or AC unit to do the work, your blower replacement might cost more.
Most HVAC pros charge $75 to $125 an hour for HVAC repairs. 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.
Cost by type (and speed) of HVAC blower motor replacement
We talked about the importance of factoring in the type and speed of an HVAC blower motor when installing a new blower. But what about the costs?
The cost of a replacement will depend on the type and speed of the blower motor. Two main types of HVAC blower motors exist.
Two main types of HVAC blower motor replacement jobs
The two most common types of blower motors include:
- Permanent split capacitor (PSC) motors
- Electronic commutated split capacitor motors (ECMs)
Permanent split capacitor (PSC) motors cost between $350 to $800. They usually have a one-speed setting that you can either turn on or off.
This motor is standard for many older furnaces. PSCs are an economic choice. Their simple functionality makes them less expensive, but they’re also less efficient.
While PSCs may be cheaper, you tend to spend more on utility bills over time.
Electronic commutated split capacitor (ECM) motors tend to cost $600 to $1,150. A bit pricier, these motors can operate at multiple speeds.
While ECMs may come with a higher sticker price, they use 75% less energy, and are more efficient then single-speed PSCs.
You may save money on your HVAC system’s blower fan in the long run given an ECM’s energy efficiency, but you can expect a higher sticker price from the get-go.
Blower motor speed types
Single-stage motors, two-stage motors, and variable-speed blower motors: when you have a bad blower motor, these are your options for replacement.
- Single-stage blower motors: tend to cost $300-$900. They operate at just one speed. While they may be less efficient, they cost less.
- Two-stage blower motors: tend to cost $320-$1,100. They operate at three speeds. They may be more expensive upfront than a single-stage motor, but once the building is cooled or heated, these motors offer greater efficiency.
- Variable-speed blower motors: tend to cost $600-$1,500. They operate at many speeds, giving people a greater chance at energy savings — and AC and furnace efficiency. While these motors come with the highest upfront price tag, they offer the best airflow and are the quietest of the three types of motors.
Table: Two types of furnace blower motors
| Permanent split capacitor (PSC) motors | Electronic commutated split capacitor (ECMs) motors |
| 1. Can come in single or multiple speeds 2. Tend to be less efficient 3. Tend to be more budget-friendly | 1. Come in multiple speeds 2. Tend to be more efficient 3. Tend to be more costly upfront |

DIY option: Average cost to replace a furnace blower motor
Many people choose to save money on blower motor replacements by replacing a motor themselves. If you’re the type of person who likes to tackle home improvement projects yourself, you can take full control over the costs of HVAC maintenance by choosing a do-it-yourself (DIY) motor replacement.
The cost to replace a blower motor yourself is $350 to $1,150. The replacement tends to cost $800 less than calling an HVAC repair company.
With a DIY option, you won’t have to pay for an HVAC technician’s labor because you’re doing the labor yourself.
Note: no matter what, we’re here to ensure you’re comfortable and healthy in your home and/or business. We would feel awful if we didn’t mention that with a DIY option, you could be spending more time and energy replacing a blower motor.
For instance, sometimes, DIY options lead to replacing the furnace motor only to discover that the blower motor wasn’t the source of the issue.
With a DIY motor replacement, we’ve seen all too often that customers spend more on the costs of HVAC repairs. Before calling us, our customers often found that with a DIY option, they realized they needed to replace other parts.
As other parts were replaced, they forked larger and larger sums of money, and they spent needless time troubleshooting HVAC issues that could’ve been solved with a quick call to an HVAC technician.
The choice is yours. Whether you DIY or choose an HVAC technician, you can’t go wrong with regular check-ups on your HVAC unit.
Other cost considerations for furnace blower motor replacements
Every HVAC unit is different. Residential blower motors are different from commercial-sized blower motors. As such, you’d be hard-pressed to find a one-size-fits-all dollar sign amount for HVAC blower motor replacements.
The cost of replacing a blower motor varies with each situation. The most common factors that could affect furnace and AC blower motor costs include:
- The cost of the newly purchased parts
- Whether you decide to repair or replace the furnace blower motor
- What the warranty on the motor includes
Let’s dive more into each factor.
The cost of purchasing new parts
One of the most significant factors in the overall cost of a furnace blower motor replacement is the cost of new parts. When an HVAC professional troubleshoots a furnace blower motor, they often need to replace other parts of the HVAC unit.
Often, an HVAC company will need to buy extra components and spend labor and energy to replace old parts. Therefore, the overall repair cost could increase as a result of purchasing new parts.
For example, when replacing a furnace blower motor, many companies have to take apart and purchase new evaporator coils and air filters inside the motor’s air handler. Therefore, the cost of replacing the motor isn’t just the cost of the motor.
The cost now includes other components, components which can add to the overall repair costs.
Repair or replace an HVAC blower motor? That is the question
To repair or replace? That is the question.
Furnace maintenance costs vary depending on whether you decide to replace or repair your blower motor.
You can save yourself time and money by reaching out to an HVAC company for a complimentary estimate on a motor replacement.
An HVAC team can give you a quick and comprehensive assessment of how much an air conditioning and heating blower motor repair or replacement will cost, all at no extra cost to you.
Warranty coverages for an HVAC motor blower replacement
If you have a warranty on your blower motor, great news! Most warranties cover the premature failure of a product if it’s within the warranty period.
With that said, most blower motors should give you 10 to 20 years of reliable performance.
If repair work is needed during the warranty period — if you choose to work with an experienced HVAC technician — labor tends to be about $150 to $250 for a blower motor replacement.
