Dirty vents aren't just unpleasant to look at - they can also be pretty dangerous for your health.
They can lead to allergies, pests, mold, and many other issues, so you should take good care of them regularly.
Here are some signs that it's time to clean your vents properly.
If you notice a buildup of visible dust, dirt, or debris on the surface, it is a strong indication that the vents are dirty and in need of cleaning.
If you notice a decrease in airflow or weaker ventilation than usual, it could be a sign of blocked or clogged vents.
If you detect musty, stale, or foul smells when the HVAC system is running, it may indicate that the vents are dirty and need attention.
If you or your family members experience an increase in allergy symptoms, coughing, sneezing, or difficulty breathing when the HVAC system is active, it might be a result of dirty vents circulating contaminants.
Dark spots, discoloration, or a musty smell can indicate the presence of mold, which requires professional attention to clean and remediate.
In some cases, pests like insects or rodents can make their way into the vents, leaving behind debris, nesting materials, or droppings.
