It’s officially spooky season. With all the haunted houses and scary movies, you may already feel on edge. There’s nothing like scary sounds in your home to really send you into a panic! Here are 5 scary sounds you should never hear coming from your HVAC system and what they mean exactly.
1. Squealing or Screeching
If you hear this noise coming from your HVAC system, it’s usually due to a problem with your motor or blower. Your blower motor might be worn out due to overheating or old age. A lot of times, homeowners experience overheated blowers because of dirt buildup or a bad capacitor. Contact an HVAC professional if yo notice any high-pitched squealing or screeching coming from your heating and cooling equipment.
Rattling noises are certainly not something you want to ignore, because they could indicate a pretty serious problem. For one, it could mean you have a cracked heat exchanger, which is the number one cause of carbon monoxide leaks. However, it could also just mean you have a loose screw that needs to be tightened. All that being said, though, if you hear rattling, you should contact an HVAC professional right away to make sure it’s not a serious issue.
Metal against metal noises are not only unpleasant, but it could be a sign of a problem that needs attention. A lot of times, scraping indicates an issue with your blower wheel. However, it could also mean there’s a loose part that needs tightening. No matter what, you should contact an HVAC professional if you hear scraping.
If your HVAC unit bangs, especially when it shuts off, it’s likely due to a dirty air filter. When your filter is dirty and clogged, it restricts airflow and causes warm air to back up into your furnace instead of out. However, once the heating cycle stops and your furnace turns off, the metal panels cool and can produce a banging noise. Like with any strange, sudden noise you hear, it’s not a bad idea to contact an HVAC professional just in case it’s a more serious issue that needs attention.
Buzzing sounds can be confusing because there are so many reasons for it. It could mean you have loose wiring, broken parts, unbalanced fan blades, or even a dirty air filter that needs replaced. Needless to say, if you hear buzzing coming from your HVAC unit, you should schedule an appointment with your local heating and cooling contractor to be safe.
