If your furnace blower motor or draft inducer is failing, you may hear you a loud noise. You should call or send us a message to have it evaluated.
- Blower motor has an issue
- The motor could be seizing up causing a humming sound or other loud noise. This could also create a foul smell.
- The blower wheel might be coming apart. This could cause a loud noise or a ratteling sound.
- Draft inducer motor may be failing
- Your draft inducer blows the flue gas out of your furnace. It has a motor and blower wheel that could be failing. This would certainly cause a humming or screeching noise.
- Ductwork popping and/or expanding
- When your furnace blower starts up, it pressurizes your ductwork. That could cause a pooping sound in the ductwork. It will also pop when the motor shuts down.
- Dirty air filter
- A dirty air filter will make the blower motor work harder to pull the air through the system. This may cuase a windy/ air noise.
- Poor combustion of gas
- When a furnace doesn’t ignite well, it can make a boom sound. This happens when burners are dirty and need cleaning.
