It’s not just hot air to say that your HVAC system can't run without its blower motor. This crucial component sits inside the air handler, sending heated or cooled air through the ducts and out of the vents where you need it most. 

The typical cost of a furnace blower motor is $450, but the final price depends on labor fees, as well as the cost of the parts. Some higher-end models feature large or hard-to-reach motors, which could bring your HVAC blower replacement cost to as much as $2,000. An active warranty means you might only pay around $150 to cover labor.

AC/Furnace Blower Motor Cost Breakdown

When you consider blower motor price, this common furnace repair cost could entail replacing the entire unit or just specific parts. This, along with your cost of labor, is what makes up the numbers on your final bill.

HVAC Blower Motor Replacement Cost

The total cost to replace a furnace blower motor can run anywhere from $100 to $2,000, but this usually accounts for the motor, fan, and house altogether. In some cases, you might save cash by replacing only the motor and leaving the other parts as is.

Here are the most common sizes for furnace and AC blower motors, plus their cost:

SizeCost Range
One-quarter horsepower$100–$550
One-third horsepower$100–$800
One-half horsepower$120–$1,000
Three-quarter horsepower$175–$1,500
One horsepower$250–$2,000

Heater/AC Blower Motor Costs for Parts

If certain parts call it quits in your blower motor, you might be able to replace them individually. Here’s a breakdown of what those could cost on their own:

  • Bearing: $20–$150

  • Belt: $5–$100

  • Blower wheel, a.k.a. “squirrel cage”: $50–$275

  • Capacitor: $150–$450

  • Housing: $100–$300

  • Pulley: $50–$250

  • Shaft: $50–$200

Labor Cost to Replace a Furnace Blower Motor

Installing a new heating and air conditioner blower motor could cost around $150 to $250, with most of that coming from labor costs. HVAC technicians usually go for around $75 to $125 per hour. A blower motor replacement might take anywhere from one-and-a-half to two-and-a-half hours.

How Much Does It Cost to Replace a Blower Motor for Central Air Yourself?

You can replace a blower motor yourself without much risk of hurting the system, but you’re likely to hit a snag in the process. 

For example, imagine investing the time and energy into replacing the blower motor, only to discover that this wasn’t why your system was having problems. Even if you successfully pinpoint a blower motor issue, you might overlook a bigger problem that caused the failure in the first place. If the latter is the case, then R.I.P. to your brand-new motor (it was so young, too).

Such is the plight of the DIY-er when it comes to HVAC repairs: diagnosing the repair often requires advanced, professional-level expertise. Sure, you might figure out the how, but you’ll likely have trouble deciphering the why. It’s best not to attempt anything until you’ve consulted a furnace repair specialist near you.

How Much Does HVAC Blower Motor Replacement Cost by Type?

Depending on the type of blower motor, your price could be on the high end or the low end. Below are the different motors and what they might cost.

Single-/Multi-/Variable-Speed Blower Motor Price

Your blower motor price depends on which type you have: single-speed, multi-speed, or variable-speed. Variable-speed motors typically carry a 50% higher price tag than single-speed motors. A more specific figure is about $450 to replace a single-speed motor, with multi-speed and variable-speed motors typically costing $600 or more.

Furnace Blower Motor Cost vs. AC Blower Motor Cost

Whether you’re looking at a furnace blower or an AC blower, both have the same average cost of $250 to $800. This is because it’s the same part that carries out both functions. Whether you chill out without central air, or you have both heating and AC, you’ll only have one blower motor to worry about.

How Much Does HVAC Blower Motor Replacement Cost by Brand?

When you figure your AC/furnace blower motor cost, you have a number of brands to choose from. Depending on which you go with, your price could vary. Here are a few top brands and their average costs:

  • Carrier: $100–$1,600

  • Goodman: $75–$800

  • Lennox: $150–$1,500

  • Rheem: $250–$900

  • Trane: $175–$1,500

  • York: $150–$1,800

What Factors Influence Your Blower Motor Price?

There’s no one-size-fits-all number for HVAC blower replacement cost, as there are many factors at play. Below are the most common points that might affect your bill.

Warranty Coverage

If your HVAC system is still under warranty, you’re in luck. Most warranties will cover the premature failure of the blower motor, so you’ll just have to cover labor for about $150.

Labor Cost to Replace Blower Motor for Central Air/Heating Systems

There are many HVAC companies out there, and you’ll see different blower motor prices based on who you hire. As always, it’s wise to get multiple quotes, but be aware that some pros charge a diagnostic fee if they come out to your home. This might be around $50 to $150, with most waiving the fee if you hire them for the repair.

Accessibility of Your HVAC System

Your HVAC system’s ease of access can play a role in your labor costs. If it’s somewhere quick and easy, such as a main-floor closet, you’ll probably get a minimal baseline fee. If your pro has to tromp through the dark depths of your attic or basement, then you might get an extra charge.

Repair vs. HVAC Blower Replacement Cost

Just like repairing vs. replacing your entire furnace, the same dilemma exists for the blower motor. Is your entire motor kaput, or is it just a small part? Repairing a blower motor costs anywhere from $150 to $1,500 based on what went wrong. On the other hand, a full replacement might cost upwards of $2,000 once you factor in labor costs. So if your repair estimate is sky-high, you might get a better value with total replacement.

FAQs

What’s the difference between an AC and a furnace blower motor?

Trick question: there is none. Whether you have central air and heat, or just one of these, the same blower motor carries both hot and cold air.

How can I tell if my furnace blower goes bad?

If your hot or cold air isn’t making it to your easy chair, this might mean that there is no blower to force it through the vent. Hearing a vibrating motor sound in the walls could also be an indicator. In any case, the only way to know for sure is by contacting an HVAC repair specialist near you.

How much is a blower motor?

Depending on the size and brand, your new blower motor price can be anywhere from $100 to $2,000.
