I am concerned about my HVAC (Heating Ventilation & Air Conditioning) Unit & the ductwork in my property. Where do I start??
HVAC units and ductwork systems play a crucial role in maintaining indoor air quality; however, they can also be a source of various Indoor Environmental Quality (IEQ) issues if not properly maintained. For instance, excessive moisture accumulation can create an ideal environment for mold and fungal growth, potentially leading to health concerns. Moreover, dust, dirt, and debris buildup within the ductwork can restrict airflow, reduce system efficiency, and contribute to poor air quality.
In addition, other potential concerns include rodent or pest activity, which can introduce allergens and contaminants into the air. Furthermore, fiberglass liner deterioration may release airborne particles that can be harmful when inhaled. Equally important, improperly sealed or open return air ductwork in unconditioned spaces such as attics, crawlspaces, or basements can lead to the circulation of unfiltered air, bringing in dust, allergens, and humidity that compromise both comfort and air quality.
Therefore, regular inspections, maintenance, and professional evaluations are essential to identify and mitigate these issues, ensuring a clean, efficient, and healthy indoor environment for occupants.
Following NADCA published guidelines, we evaluate the current condition of the HVAC System & ductwork to locate these potential issues. We can provide guidance & instructions as to how the problems can be resolved by a Licensed Mechanical Contractor and/or Certified Restoration Company.

What type of filter media should I install in my HVAC (Heating Ventilation & Air Conditioning) Unit? What about Ozone & UV Light?
There are numerous types of filter media available for installation in both residential and commercial HVAC units, each designed to enhance air filtration and improve indoor air quality. At American Metropolitan Environmental, Inc., we believe that selecting the appropriate filter type and size should be determined on a case-by-case basis, as different environments have unique filtration needs.
To ensure the best choice for your system, we strongly recommend conducting thorough research and consulting with your Mechanical Contractor. With their expertise, they can assess your specific HVAC setup and recommend the most effective filtration solution for optimal performance and air quality.
