What Is That Noise? A Few Common HVAC Noises

Have you heard that weird noise coming from your HVAC? Is this your wake-up call? Home appliances make such noises many times – a refrigerator running and the dishwasher spraying water on dishes. We all get used to these. It does not matter what is the age or price of your HVAC system, it can start to make noise anytime.

During the winter season, your HVAC system runs continuously. That is why hiring a professional to inspect the issue is always recommended. When you are hearing an unfamiliar loud noise coming from a dishwasher, air conditioner, and any other home appliances, take notice. Here are a few common noises coming from HVAC.

  1. Squeezing and screeching: Squeezing and screeching sounds are the clear sign that you need to replace a belt or motor bearing. The solution depends on how loud the noise you are hearing. You can fix the problem by lubricating the problematic belt. If you cannot do this on your own, you can call a professional.
  2. Click Click: When the weather is changed and winters start and you turn on the heat to make the environment of your house warm, clicking can be a welcome sound as an indicator that your unit is powering up. If the unit is already on and you hear a weired clicking sound, something might be wrong.
  3. Popping: Popping sound coming from the unit is a very common sign. It is a sign that cold ducts are expanding in the heat. If you hear the sound continuously and don’t stop, you should have to look at your system to find out the issue.
  4. Rattling: Rattling sound is a signal that loose debris is blowing around within the unit. Sometimes a loose screw also leads to significant problems down the line. If you have debris and dust in high amounts, the rattling sound coming from the system is more likely a scraping noise. You can not ignore it.

If you want to find the issue yourself, turn off the unit first. Get in touch with Infiniti HVAC, our experienced technicians will be able to diagnose the problem and let you know if it can be repaired or you need a replacement.
