While the cold is easing out, it is early spring and you might still need to use your furnace to keep your home comfortable. And while it is late in the season, if you begin to hear some strange noises coming from your heating it isn’t something to simply ignore until next year. It could mean you need furnace repair in Cupertino, CA. And the sooner you resolve the problem, the better. So pay attention to the weird noises. It could be something minor, but nevertheless, it is a good reason to call a specialist to come out and take a look. Here are a few noises to pay special attention to, and what they might mean:
Wheezing
No, you probably don’t have a ghost in your HVAC system. The first thing to do is to check your air filter, especially if you haven’t checked it in over a month. This is the usual cause of harsh wheezing sounds and replacing the filter should remedy the problem.
Loud Thuds or Booms
Thumping noises are alarming. They could be harmless and simply the result of ducts expanding or contracting with the heat and cold. Or it could be a more serious problem with the furnace’s burners. They might need cleaning. On some models, this is a task homeowners can perform. You can remove them, clean them with hot, soapy water, rinse them, and let them dry completely before reinstalling. Or it might be a more complex system where you should call an expert. Thudding can also come from a defective gas valve and you should absolutely call a technician to come and check out your system.
Screeches or Squeals
Screeching is never a pleasant noise and should not be part of your furnace’s normal operation. Whether loud or soft, it is almost always a sign of trouble. Most likely it is a problem with the motor or belt. It might be damaged or obstructed. If not, a bearing might be the source of the sound. These are not problems you should try to diagnose and service yourself.
Metallic Scraping
You never want to hear metal scraping on metal. This usually means there is a serious issue that could eventually ruin your system if not repaired right away. So if you do hear this sound turn your system off right away and call an HVAC technician. Hopefully, it is just the blower wheel scraping against the casing. This is a fairly common problem and the technician might simply tighten the existing wheel. If the problem is more extensive you might have to get a replacement for the damaged part.
