If the blower fails to operate, you won't receive any heated air through the vents in your home. If the blower isn't turning on at all, this is a symptom that can indicate a full replacement motor is necessary.
Replacing a furnace blower motor costs $560, on average. Depending on the size and type of motor, most people pay $300 to $900.
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.
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. If this happens and the motor is no longer operable, a new blower motor may be needed.
No Airflow from Vents
If the blower fails to operate, you won't receive any heated air through the vents in your home.
The replacement of the blower motor is common and straightforward, so most shops will perform the repair — many on the same day.
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 heat exchanger replacement is often one of the most costly repairs in a furnace, and the expense can sometimes rival that of installing a new furnace. Typical replacement costs vary widely but can easily reach several thousand dollars, especially if labor costs are factored in.
If your motor's electrics and bearings are constantly exposed to too much heat, then they will begin to fail. If you let your motor overheat repeatedly and fail, then either a component has broken or a bearing has seized.To prevent overheating, check your vents, filters, and in-room airflow.
Undo the screws on the motor to remove the belly band. The rotation of the motor needs to match the direction of the fans, so position them accordingly. Attach the new motor to the belly band. Center the new motor on the fan wheel, fasten the bolts, and connect the capacitor.
What is the average life of a residential furnace? A furnace that receives regular maintenance can last at least 15 to 20 years, but completing annual maintenance and being diligent with repairs can extend the life of a furnace even longer.
Your AC's blower motor is responsible for moving air through your air conditioner to cool it and then pushing it back out into your home. Without this incredible component, your AC can't provide any cooling effect, no matter how much the compressor runs.
While costs can vary, homeowners can typically expect the following range: Standard Blower Motors: These might cost between $400-700, excluding labor. Advanced Multi-Speed or Variable-Speed Motors: These are generally more expensive, with costs ranging between $650-1250, not including labor.
If it happens, you will hear unusual noises like slapping or sudden pop coming from behind the vent. Problems with the airflow have signs such as ongoing whirring, getting louder when you increase the fan speed.
Repair: If your furnace system is less than 15 years old and the cost of repair is less than half the cost of replacement. Replace: If your furnace system is more than 15 years old and requires a costly repair to maintain efficiency.
Most experts recommend getting three to five HVAC quotes from licensed, insured, reputable local heating and cooling companies. Getting multiple detailed HVAC quotes (but not too many) lets you compare the equipment, services, and prices of several contractors without being overwhelmed by options.
Some of the reasons a blower motor might fail are overheating, and excessive moisture. When dust, dirt, and debris build up, it can cause the windings and bearings to burn up more quickly.
Blower Motor Fuse Problems
A blower motor fuse is a critical component of the heating system. If the fuse is blown, the blower on the furnace won't turn on, leaving your home without proper heating. Inspect the fuse box for signs of damage and replace any blown fuses.
The most common reason why your blower motor won't work on any speed is that you have a bad or blown a fuse. A fuse is a small wire inside of a connector that is used to protect the motor itself from a surge of electricity.
Recognizing the signs of a failing AC blower motor can help you take prompt action and avoid further damage to your HVAC system. Some typical indications of a malfunctioning blower motor include weak or no airflow from the vents, strange noises or odors, increased energy bills, and HVAC unit overheating.
In general, it can take two to three hours to replace a typical blower motor.
Parts Coverage: Most warranties cover the blower motor and related components. Labor Coverage: Some warranties may include labor costs for repairs or replacements, but this is rare. Exclusions: Normal wear and tear, improper installation, and lack of maintenance are usually not covered.
