Signs That There Is Mold In Your HVAC System

Mold in your home can be dangerous, but mold in your HVAC system, including the unit itself, your ductwork, or the vents can be especially worrisome. That is because if there is mold in any of these areas, it can be constantly blown into your home as the system heats and cools your home. This causes it to quickly spread from one part of the home to the other and makes it easier to breathe in the spores. Unfortunately, though, you cannot see inside your HVAC unit or system. This can make it tough to tell if you have mold. On the upside, you are often given many clues that mold may be present. Here are a few of the signs that there is likely mold in your HVAC system. 

You Smell a Musty or Mildew-Like Smell

One of the tell-tale signs that there is mold in an HVAC system is a musty or mildew-like scent that seems to come from from the system. You may smell this scent stronger when you are directly under a vent in your home or when your heater or air conditioner kicks on. Typically, the scent is stronger in the areas where mold is most present. If the mold is strongest in one part of your home when the HVAC kicks on, it may be because the mold is in the ductwork that leads to that part of the home. If the scent seems consistent throughout your home, it may be because the mold is in your HVAC unit itself. 

You See It On Your Ventilation Grills and Filters

Another sign that there is mold in your HVAC system is physically seeing signs of the mold itself. It is important to understand that mold comes in different colors, including green, black, and yellow, and it has different appearances. It can look thick and fuzzy or it can look spotty or chalky. If you have mold, you may notice mold on the filters that you are replacing in the HVAC unit, in your ductwork, or see mold on the ventilation grills and fins. If you see what you know or suspect is mold, you need to have mold remediation to properly remove it. 

Someone in Your Home is Mysteriously Ill

The last sign of mold in your HVAC unit is someone being mysteriously ill in your home. Mold can cause people to develop rashes, suffer from headaches, have respiratory problems, or feel sick. If you or someone in your home suddenly develops an unexplained illness that just won't seem to go away, you may have mold present somewhere in your home, such as your HVAC unit. 

If you notice these signs, there is a good chance that there is mold in your HVAC system. Contact an HVAC specialist or a mold removal company to inspect the system, determine what type of mold is present and how much, and then properly remove it. Not only will this help you to stay healthy, but it will help extend the life of your HVAC unit and your ductwork as well.
