It is the middle of winter and you expect your home to be warm and cozy. Yet, you feel increasingly chilly. You go and check your furnace and realize that there’s no sound and airflow coming out of it. Your furnace blower motor has completely stopped working. Why has this happened? How do you bring your furnace back in good working order and ensure the comfort of your San Diego home?
There are numerous reasons why your furnace blower motor may have stopped working, some of which can be easily fixed while others may require assistance from furnace repair professionals.
How do you know if your furnace blower motor is faulty?
Just like many other HVAC components, the furnace blower motor is subjected to wear and tear that may cause mechanical failures over time. If your furnace keeps experiencing issues, the blower motor may be the culprit and might need to be replaced. Here are some signs you should look out for if you suspect that your blower motor is faulty:
- Weak airflow: this is one of the first indications of a failing blower motor that you may notice. Check the airflow coming out of your vents – if it’s weak, the blower motor may be having a hard time distributing the air through the ducts in order to achieve the set temperature.
- No airflow: if there’s no air flow coming out at all, your blower motor may be experiencing more serious issues and may need to be replaced, unless clogged air filters, incorrect settings, or a blown fuse are to blame.
- High energy bills: the blower motor of your furnace is one of the components that use the most energy. If it’s old or faulty, it will work much harder to distribute the heated air throughout your home, causing your energy bills to spike.
- Unusual sounds: hearing unusual noises coming from your furnace is rarely a good sign. Make sure to contact professionals if you notice screeching, squealing, rattling, banging, or clanking sounds coming from your unit.
- Overheating issues: a blower motor might overheat due to a number of factors, including grime and dirt buildup and age. An aged and worn out blower motor will struggle to heat your home, causing it to overheat.
If you notice any of these warning signs, make sure to contact reliable HVAC contractors as soon as possible to prevent more serious damage and keep your furnace in good condition. However, make sure to attempt some of the easy fixes listed below before you go on to look for blower motor repair or replacement options.
What can cause a blower motor to stop working?
If your furnace blower motor isn’t working, the following culprits may be causing the issue:
A tripped circuit breaker or a blown fuse may cause your furnace to stop working. If this is the case, reset the breaker or replace the fuse to resolve the issue. Wait a couple of minutes and turn on the furnace to see if the blower motor starts working again.
It may be the case that your furnace blower motor isn’t working because the thermostat isn’t set appropriately. If the settings are too low, your furnace may think that you’re perfectly cozy at 50 degrees. Adjust the thermostat settings and check if that fixes the problem.
Your furnace filters should be cleaned or replaced on a monthly basis during the heating season. If they aren’t, the accumulated dirt and debris may significantly decrease the airflow and prevent the blower motor from working.
Some blower motor malfunctions will require professional assistance. The furnace capacitor may be failing or the blower itself may have a serious problem that requires servicing or a replacement. If none of the previously mentioned steps bring your furnace back to good working order, contact your HVAC professionals of choice.
How hard is it to replace a furnace blower motor?
If your blower motor is irreparable, a replacement is your only option. The replacement process can only be performed by a professional who is familiar with different types of furnaces and blower motors. HVAC experts can recommend a blower motor replacement suitable for your furnace, taking into account factors such as rotation direction, voltage, horsepower, capacitor size, motor diameter, and type of drive.
Once you’ve selected the best replacement for your furnace blower motor, your HVAC contractors will most likely give you a cost estimate and arrange the installation.
How much should it cost to replace a furnace blower motor?
Furnace blower motors can vary in cost depending on the model. On top of the cost of the blower motor itself, you’ll most likely also need to pay for the installation work, the cost of which will differ depending on the HVAC contractors you hire.
In general, HVAC blower motors tend to cost about $450 on average, while the replacement costs may range anywhere from $150 to $2,000. It won’t matter whether you have an electric heating system, a heat pump, or a gas furnace, as all of these units use air handler blower motors to push and distribute the heated air throughout the air ducts in your home.
