Heating, Ventilation and Air Conditioning Systems (HVAC) 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.
Frequency of cleaning depends on several factors, not the least of wich is the preference of the homeowner to consider more frequent cleaning include:
Research by the U.S Environmental Protection Agency has demonstrated that HVAC system cleaning may allow systems to run more efficiently by removing debris from sensitive mechanical components. clean, efficient systems are less likely to break down, have a longer life span and generally operate more efficiently than dirty systems.
Antimicrobial chemicals are applied by some companies 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.
