What is a furnace blower?

furnace blower

The term furnace blower can be misleading because it refers to two different components. A furnace blower is composed of a blower fan and blower motor, and if either of these parts breaks down, your HVAC system isn’t going to function properly.

The sole purpose of this part of the HVAC system is to move the hot air through the ducting, and if the motor or the fan stop working you, warm air won’t reach the inside of your home.

Moreover, the HVAC system will start consuming more power than usual because the blower has to work harder to move the air through the system.

Even furnaces manufactured by the same brand have different blowers, and if one of the components fails, you need to get a recommended OEM part. Motors break down more often than fans, so this is the component of the blower setup you’ll be looking for in most cases.

Understanding how a furnace blower works

The temperature you set on the thermostat serves as a guideline for the entire system, and once the room temperature rises or drops, the thermostat sends the signal to the system to start working. The furnace then generates hot air by either combusting gas or using electricity and engaging the heat exchanger.

The blower motor starts the fan that moves the air that comes through the heat exchanger and pushes it towards the indoor air handler. A malfunctioning blower creates the risk of overheating the system as the air generated by the furnace doesn’t circulate through the system as it should.

On the other hand, if the furnace blower fails, reaching the room temperature you set on the thermostat will become virtually impossible as the airflow through the air vents will either drop considerably or stop entirely.

Types of blower motors


Depending on their type, HVAC systems utilize several different versions of blower motors. They’re divided into several different categories based on their power consumption, noise levels, and operating speeds.

  • Direct drive motorsThe vast majority of modern furnaces are equipped with direct drive motors that are installed directly onto the furnace blower wheel.
  • Belt drive motors – In case you still have a furnace manufactured a couple of decades ago, chances are that it utilizes a belt drive blower motor. Unfortunately, these motors are not energy efficient, and they often generate a lot of noise.

You can also distinguish between different blower motor types based on the number of speeds they have.

  • Single-speed motors – As implied by their name, these motors can only operate at their maximum capacity. Consequently, they consume vast amounts of power to keep the air circulating through the system.
  • Multi or variable speed motors – Even though both motors have more than one speed, multi-speed models offer less versatility in speed adjustment. Variable speed motors grant you complete control over their speed, but they’re considerably more expensive than any other type of blower motor.

During your search for a replacement blower motor, you may encounter terms like PSC or (permanent split capacitor) or ECM (electronically communicated motor). However, these terms often refer to single-speed and variable speed motors, although a PSC motor can sometimes have multiple speeds.

Finding the OEM blower motor

Blower motors are usually durable, and they can last for more than 10 years, but poor maintenance can shorten their lifespan. So in case you’ve determined that the blower motor is the reason why your HVAC system isn’t functioning properly, you will have to replace it with a compatible model.

Ideally, you should check the motor’s serial number and get an identical model. Doing so will ensure that the new motor is compatible with the system and that you won’t have any problems connecting it to the blower.

If you cannot find the same motor, your best option is to search for a universal OEM model compatible with your furnace. However, this might be a difficult task, as the new motor needs to match the original part’s diameter, drive, speed, horsepower, and mounting method.

Installing a new blower motor

Replacing a blower motor isn’t difficult, and you don’t have to hire a professional to do this job for you. The first thing you need to do is to remove the old motor, but make sure to memorize the wire colors and how they’re connected to avoid complications while reconnecting the blower to the furnace.

You should then remove the bolts that connect the entire blower to the furnace and take it out. Next, proceed to detach the motor from the blower wheel and then remove the fasteners that connect the motor to the housing.

To install a new motor, you should perform the same procedure in reverse, so you should start by attaching the motor to the housing and finish by connecting the wires to the furnace control board. Then, go through our guide to the best HVAC tools to find the tools you need to install a new blower motor.

The most important factors to consider while choosing a furnace blower

In theory, the process of replacing a furnace blower shouldn’t be complicated since you just have to find out the serial number of the original motor or fan and then get the same model.

However, the furnaces have a long lifespan, and their components often go out of production, which complicates the process of finding replacement parts for old furnace models.

Universal or OEM furnace blower motors are your only option if the original model is no longer available, but you must make sure that the motor you want to get is compatible with your HVAC system. Let’s take a look at several factors that can make the search for a replacement furnace blower easier.

Find the source of the problem

Furnace Blower 1

You need to determine the reason why your HVAC system’s heating or cooling capabilities are no longer at 100%. The best way to do this is to test different components of the system and rule out all other possible causes of the problem.

Sometimes a faulty capacitor can be why the system is consuming more power than usual or making a lot of noise. Once you’re absolutely sure that the problem comes from the furnace blower, you should determine if you need to replace the fan, the motor, or both components.

Search for an identical replacement part

You cannot replace a single-speed motor with any other type of furnace motor. What’s more, even the same type of furnace motor might have more horsepower, a wider diameter, or a different rotation direction than the blower motor on your furnace.

You should try to contact the manufacturer and obtain the same part as the one you want to replace. If the particular motor or fan model is out of production, you should search for an OEM part compatible with your furnace.

Check the maintenance requirements

Most furnace blowers have low upkeep requirements regardless of the motor or fan they’re using. Cleaning the fan before the start of the heating season, lubricating the motor, and inspecting the motor belt regularly are the only maintenance actions you’ll have to perform.

Despite regular upkeep, some components of the furnace blower motor, like the resistor or climate control switch, may break down unexpectedly. That’s why the best way to avoid potential problems with an HVAC system is to have a licensed technician inspect its components once per year.

Calculate the replacement costs

The price of a furnace blower motor depends on its type, so a single-speed motor will costs between $100 and $300, while a multi-speed model can cost from $200 to $600.

Variable-speed furnace blower motors are the most expensive, as some models can cost more than a thousand dollars. Professional replacement of the furnace blower can cost between $300 and $800, depending on the size of the system.

Opting to install the new components by yourself can save you a lot of money, but you should keep in mind that failing to connect the wires properly or making some similar mistake can cause damage to the entire HVAC system.

Consider replacing the entire HVAC system

A malfunctioning furnace blower can be a sign that the entire HVAC system is failing. Sometimes getting a new heating or cooling system can be a more affordable option than repairing the old one.

You should consult with a licensed HVAC technician to determine if replacing a broken furnace blower is the best course of action since you may spend vast amounts of money just to deal with a different issue a few months later.

The advantages of furnace blowers

Furnace 1

Essential components of HVAC systems

You cannot use an HVAC system without a furnace blower as this component pushes the air through the system. That’s why you must perform regular maintenance checks to make sure that the motor and fan are in good condition.

Long lifespan

All components of furnace blowers are designed to withstand heavy usage. Their average lifespan is between 10 and 12 years, which means that they’re almost as durable as the HVAC system.

Simple replacement process

Experienced DIYers don’t have to spend hundreds of dollars on the installation of a new furnace blower, since with access to the right tools, they can replace the motor or the fan by themselves.

The disadvantages of furnace blowers

Limited availability of original parts

Finding the original replacement parts for your furnace blower may be difficult, especially if your furnace is more than ten years old. Universal motors and fans are usually compatible with a handful of furnaces, and you need to check if the model you’re interested in can be fitted on your HVAC system.
