5 Sources of Weird Furnace Noises in Saint Petersburg, FL
You shouldn’t ignore noises coming from the furnace in your Saint Petersburg, FL, home. While sometimes there is no cause for worry, it can be a sign of a serious problem. In this article, we’ll look at some sounds you may notice from your furnace and what they mean.
1. Loud and Continuous Humming
A low hum is normal for most equipment in your home, such as your furnace. The transformer may produce a similar sound when your furnace is new. If the humming is loud and continuous, it could signify a malfunctioning fan or capacitor.
2. Grinding or Screeching Sounds
You may notice grinding noises such as metal rubbing against another metal coming from your furnace. The sound is usually a sign of a loose blower motor scrapping against its housing.
When the blower wheel is loose, you may also notice vibration, screeching or rattling. The next best course of action is to switch off the system and schedule for repairs.
3. A High-Pitched Squealing Noise
If you notice a high-pitched squealing noise, the most probable cause is your blower motor. Lack of lubrication may be causing friction within its moving parts.
