Air ducts play a huge role in the quality of air your home gets from your HVAC unit. Your ductwork has a series of connected tubes that distributed heated or cooled air to the rooms throughout your house. While the Environmental Protection Agency recommends cleaning your ducts on as needed basis, it’s important to check them from time to time as they get clogged and dirty.
Here are some warning signs that indicate it's time for a comprehensive air duct cleaning:
Visible Mildew and Mold Growth
If you start noticing the presence of mold in your air ducts, it could indicate that the ducts have accumulated dirt, which has led to the growth of the mold. Mold not only affects your quality of air, it can also lead to serious respiratory problems especially for people with asthma and other allergies.
This is a very noticeable sign. When your turn your heating or cooling unit and notice that air is not coming out of the vents like it used to, this could indicate broken connections or blocked ducts. Have this problem fixed by an air duct cleaning professional.
This majorly occurs when your ducts have been exposed to harmful elements or they have been damaged. These ducts allow in moisture and this makes your rooms humid all the time.
Insect Infestation and Rodents
Droppings or small scratches along the side of your air ducts and husks from insects indicate that your ducts have been infested and it’s time to have them cleaned.
Dirt and Debris
When your air conditioning or heating unit is turned out and stuff blows out of them, it indicates that dust and debris have accumulated in your air ducts. Accumulated dirt only makes your unit work harder than its supposed to and leads to high energy bills at the end of the month.
If you notice any of these signs, you need to call in a professional and experienced HVAC contractor to have your ducts cleaned. In some cases, the ducts may have to be repaired to ensure that you come home to a cool environment.
