There are several common misconceptions surrounding air duct cleaning that discourage many homeowners from getting this important service. However, when the facts are examined, it becomes clear that regular duct cleaning delivers numerous health and efficiency benefits. Here we’ll debunk 3 common myths surrounding duct cleaning.
Myth #1: Clean ducts are only needed for old homes
Some believe that only older homes with corroded or decrepit ducts require cleaning. However, all ducts accumulate dirt, dust mites, mold spores and other particles over time. This buildup occurs in both new and old homes, and neglecting regular cleaning can lead to health issues regardless of a home’s age. In fact, recent studies show newly constructed homes may contain higher levels of contaminants within ducts due to materials used during construction.
Myth #2: Duct cleaning makes no noticeable difference
Many doubt that duct cleaning yields meaningful benefits. Yet research consistently shows that professional cleaning removes on average 80% to 90% of accumulated dust and contaminants from air ducts. This reduction in allergens and irritants circulating throughout a home certainly makes a huge difference for allergy and asthma sufferers. Additionally, clearer coils and a freer air flow path improve system efficiency.
Myth #3: I already clean my filters, so ducts are clean too
While replacement filters do capture some particulate matter, they do not remove contaminants that accumulate directly within the ducts themselves. Filters only clean the air that passes through them, meaning only a portion of the air in a HVAC system is actually filtered at any given time. Professional duct cleaning is needed to remove residue that builds up on the interior surfaces and hard-to-reach areas of the ventilation system.
In conclusion, all ducted HVAC systems benefit from periodic professional air duct cleaning regardless of a home’s age. Regular cleaning removes volumes of contaminants that filters miss, delivering proven health advantages as well as efficiency gains. Rather than relying on myths that discourage maintenance, homeowners should consider the facts about the benefits of proper duct care.
