HVAC Noises Explained
The spin of the dishwasher, the rolling of the garments dryer, and that gentle hum of an HVAC unit are all sounds you're likely accustomed to! So, it makes sense for any strange sound to concern you.
Keep reading to learn more about the reason behind some common HVAC noises.
Banging, Thumping, or Rattling Sounds
Rattling, banging, or thumping sounds are pretty common and can be caused by a few factors. Without inspecting your device and diagnosing the problem from what you see, there's no way to tell exactly what the problem is.
If this noise is coming from above your ceiling, it may be a ductwork issue. The ductwork that's wearing down with time or ductwork that wasn't effectively installed can cause strange sounds. There could be a problem with the air pressure in your ducts, which can be resolved with duct securing.
Howling or Squealing Sounds
High-pitched sounds like screeching and squealing are also common, but they're the most frustrating. If your system is making one of these noises, our guess is that your system is well past its prime.
HVAC units made 10-20 years ago use a belt-driven electric motor. Similar to other machinery that uses belts, like cars and clothing dryers, you hear that squealing sound when the belt loosens up. The repair service required is to change the belt, and Best Owner Direct HVAC can help with that. We also advise you to start thinking of replacing your unit if your system is over a decade old. You won't have to worry about repair services for many years.
Humming, Vibrating, and Grumbling Sounds
Grumbling and humming sounds are dead giveaways of an electrical problem. There might be an issue with the wiring, motors, or even the link to the circuit breaker. It'll be hard for you to figure out the main issue yourself.
When you hear these sounds, it's best to act quickly to avoid further damage to your machine and your home's electric system. Get in touch with our team of HVAC technicians at Best Owner Direct HVAC for professional repair work.
