Common Sounds and Causes

It is important to know that some air units are louder than others. Older units tend to be louder than newer units, as the technology and designs have improved over the years. If you feel like your HVAC system is too noisy, please contact a Biggs HVAC professional so that we may check out your air unit and provide you with some options.

The noise could be as simple as a dirty fan blade or parts that require lubrication, but some noises may require immediate attention.

Here are some examples of common HVAC noises:

Whistling‑ If your air system is making a whistling or hissing noise, this could be a problem with your ductwork. A hissing noise coming straight from the HVAC unit is often an indicator of a refrigerant leak. If this is the case, trust a Biggs HVAC professional to resolve this problem.

Grinding – A grinding noise coming from your HVAC unit is most likely something to do with the fan motors. This noise is usually a sign that something is going wrong with the fan motors that needs to be addressed.

Clattering – If your air system is making a clattering or rattling noise, it could be that an outdoor debris, screw, or bolt has either fallen into your unit’s vents or become loose. A clattering noise could also indicate a problem with the unit’s compressor. As the motor begins to age, it may begin to make more noise which would be the first signs of a compressor problem.

Popping – A popping noise coming from your ductwork is usually an issue with your ductwork vs. your HVAC system. As ductwork ages, it requires maintenance so that your HVAC system can continue to effectively and efficiently cool your home.
