Finding mold in the home is something that will send a lot of homeowners into anxiety. One of the reasons for such a kind of reaction is because uncontrolled mold can lead to severe respiratory illnesses, skin reactions, and eye irritations. Some people may develop asthma after extended exposure to mold. Mold may go unnoticed in your HVAC system until it accumulates to perceptible levels. A maintenance technician should be able to alert you of mold in your system and advice you on ways to get rid of it. However, in the absence of professional help, these are the signs that you should look out for that indicate there is mold in your HVAC system.

A pungent smell

The first indication of mold in your HVAC system is an unpleasant smell. Mold has a unique stale smell and it will make your home smell unpleasant and old. The smell is something like bad food from the fridge, old clothes, or even pungent European cheese. You may notice the pungent smell increases when you run your air conditioner and that is a sure indication that there could be mold in your system.

Visual signs

The mold you will find in your HVAC system often looks just like the mold you will find elsewhere in your home. If you suspect that there may be mold in your HVAC system, open up a grate and look inside using a flashlight. If you see off-color or black spotting and irregular blemishes, then you definitely know that there is mold present in your system. In more severe cases, mold will be visible on your AC registers on the adjacent wall, ceiling, or floor and outside vents. The inconsistent black residue may not easily wipe off and will require thorough cleaning to remove permanently. If this is the case, you should call a professional immediately.

Excessive moisture

Sometimes you cannot be able to visibly see mold. However, it still thrives on excess moisture and humidity. Any space with high levels of moisture is a risk for mold. Common molds require the wet environment to flourish. Air conditioners run recurrently, allowing debris and moisture to build up in the ductwork and air handler. If you notice any, chances are high that mold is just nearby.


Recurrent respiratory symptoms

If mold was not a cause of adverse health consequences, a lot of homeowners would probably not worry about its presence in their homes. However, mold can cause anything from minor irritation to serious respiratory illness that may even lead to hospitalization. Aside from mold causing health issues, it can also affect the overall value of a building or home.

For serious mold issues, you will have to contact a mold remediation expert or an HVAC specialist who carries the equipment required to clean the air conditioning system comprehensively. Mold is a serious but easily addressed concern for business and homeowners who depend on their HVAC systems to regulate the temperatures in their premises.
