Typically, the lifespan of furnace blower motors spans from a minimum of 10 years up to about 20 years, with most enduring an average period between 15 and 20 years. The same blower motor is used for both
Blower motors are designed to last just as long as your furnace itself, anywhere from 10 to 20 years. Just as with any HVAC system, the better maintained and serviced your equipment is by experienced HVAC technicians the longer it will last and the fewer repairs you'll face.
A blower motor should last at least 10 years, and could last up to 20, depending on the type of HVAC unit you have in your home. There are a few warning signs that your blower motor is damaged, including little-to-no airflow coming from your vents, a burning smell, and skyrocketing energy bills.
Blowers. From this table, blowers have an average effective life of 15-20 years.
Typically, the lifespan of furnace blower motors spans from a minimum of 10 years up to about 20 years, with most enduring an average period between 15 and 20 years. The same blower motor is used for both heating in the winter and cooling in the summer, making it essential for maintaining indoor climate control.
An HVAC blower motor will occasionally fail due to age, wearing out, or not being cleaned regularly. Symptoms may include strange noises, burning smells, or just plain refusing to turn on.
Cost for a single-stage blower motor could run between $300 and $900, while cost for a variable-speed blower could be between $600 and $1,500. Remember, though, the higher upfront costs for a variable-speed blower motor will be offset by reduced monthly energy bills.
Not All Fans Are Designed to Last
Long-lasting fans are designed to last 50 years or more with regular maintenance. Inexpensive, disposable fans are unlikely to last more than three years with normal usage. Most mid-range fans are designed to last 6-10 years.
Faulty Blower Motor
If your blower motor is experiencing some issues, you may hear a high-pitched squeal or whistling sound. You may also experience rattling and loud screeching noises. The motor blower pushes warm air out of the furnace through the ducts into your home.
Most blower wheels need to be pulled and cleaned every 3-5 years, depending on usage and the home. A dirty blower wheel can negatively affect the airflow in your HVAC unit, causing your heat exchanger to overheat and AC coils to freeze. It will also reduce the efficiency of your blower motor and your entire system.
The average cost for a Blower Motor Resistor Replacement is between $119 and $154. Labor costs are estimated between $43 and $54 while parts are priced between $76 and $99. This range does not include taxes and fees, and does not factor in your unique location. Related repairs may also be needed.
When maintained properly, leaf blowers can last for 10 years or more. Typically, electric leaf blowers last longer than their gas counterparts, but you can enjoy many years of use for both types of leaf blowers.
The average lifespan of a furnace blower motor typically ranges from 15 to 20 years. However, this estimate can vary based on several factors. High-quality, well-maintained motors tend to last longer, while cheaper or neglected units may fail sooner.
If your blower motor is not functioning properly, it can't circulate air through your AC system, causing the evaporator coil to become too cold and eventually freeze up.
A blower motor replacement costs $580 on average, with a typical range of $250 to $900. With a warranty, you might pay as little as $150 for labor alone. For high-end models or complex jobs, like those with large motors or access issues, you might pay as much as $2,000.
Your blower motor may show these signs when it starts to overheat: A hot or burning smell as your units operate. It is usually followed by the complete furnace shut-off. Loud humming noise and other odd sounds.
Start troubleshooting by checking your circuit breaker, thermostat settings, and air filter condition. Basic DIY steps include testing airflow strength, examining the pilot light, and inspecting for obvious damage. For electrical problems, use a multimeter to check connections and components.
Replacing the blower motor is likely the best decision if your furnace is under warranty or relatively new. It might be better to replace the furnace if it's old or has a lot of issues that require frequent repairs. On average, a new blower motor costs $300 to $900.
You should inspect your air filter for any signs of dirtiness and replace it annually as most filters require. Another reason why your leaf blower might start and then stall is due to old gas. Old gas that is past its shelf life, which is longer than 3-6 months, can cause a blockage in the fuel filter and carburetor.
The replacement of the blower motor is common and straightforward, so most shops will perform the repair — many on the same day.
