Frequently Asked Questions
Are there any health benefits that come from HVAC system cleaning?
Heating, ventilation, and air conditioning (HVAC) systems have been shown to collect a variety of contaminants such as mold, fungi, bacteria and very small particles of dust that have the potential to affect overall health, The removal of such contaminants from the HVAC system and home should be considered one component in an overall plan to improve indoor air quality.
What are antimicrobial chemicals and why would they need to be used?
Antimicrobial chemicals are applied to the interior surface of the air ducts to treat microbial contamination such as fungi (mold), viruses or bacteria. Before any antimicrobial chemicals are used, the system should be thoroughly cleaned. It is critical that any antimicrobial treatment used in your system be registered by the U.S. Environmental Protection Agency specifically for use in HVAC systems.
