How To Recognize Mold in Your HVAC System

Mold can grow in a lot of places, and your HVAC system is one of them. You want to get rid of mold as quickly as possible because it can pose a health risk. With the right tips, you will be able to inspect your system for any signs of mold. Here’s how to recognize mold in your HVAC system.

A Musty or Unpleasant Odor

One of the most common ways that homeowners find out they have mold growing in their HVAC system is by noticing an unpleasant odor around their home. When mold becomes more severe, it will typically emit a distinct smell, often described as earthy or musty in nature.

If mold is present in your air ducts, this musty odor will be strongest when your HVAC system is on and running. The air within your system can pick up the mold spores and carry them throughout your air ducts, spreading the mold. This spreading of the spores will make the moldy smell more noticeable. It can be more difficult to detect this smell and its origin when your HVAC system is not running.

Visible Spots of Mold on Ducts

Visible spots of mold on your air ducts are another indicator that you have mold in your HVAC system. You likely don’t spend much time looking at your air ducts, but it can be beneficial to inspect them often to make sure you don’t spot any signs of mold. When inspecting your ducts, look for any spots that are green, black, or white in color.

If mold is present in the HVAC system, the spores will often settle on the vents, as this is where the air travels through your home. If you notice these signs of mold, you should consider contacting a professional air duct cleaning service to help you get rid of it. Mold is one of the primary reasons you should have your air ducts professionally cleaned.

Experiencing Allergies or Illness

Another sign that mold may be present in your HVAC system is if you or your family members are experiencing allergies or illnesses. Mold can pose a significant health risk, which is why you should address this issue as quickly as possible.

If you are experiencing allergy symptoms like coughing, sneezing, difficulty breathing, and itchy, watery eyes, especially in the air-conditioned rooms in your home, mold may be present. In extreme cases of mold exposure, symptoms can include nausea, vomiting, fatigue, and diarrhea. If you start to notice these kinds of symptoms, stop using your HVAC system immediately and contact an inspector or remediator.

Stay on the lookout for these common signs that mold is growing in your HVAC system. The sooner you recognize and take care of the problem, the better.
