Leaky Return Ducts Create a Dusty Home
Pollutants from unconditioned spaces get sucked into your ducts leaving you with lots of dust and poor air quality.
Sealing air return ducts is important to you and your family’s health and well-being. The American College of Allergy, Asthma & Immunology estimates that 50% of all illnesses are caused by poor indoor air quality (IAQ). The EPA lists indoor pollution as one of the top five environmental risks to public health, causing 8.5 million deaths each year.
Leaky return ducts will result in having:
– Dusty home and more frequent filter changes
– Poor and unhealthy indoor air quality
– Uncontrollable humidity problems
– Possible mold growth inside of your ducts from moisture
– Increased energy consumption
What Are Return Vents and Where Are They Located?
Return vents (also referred to as cool air return vents) pull the air from your rooms into your return ducts and send it back to your heating and cooling system. Return vents are usually larger than supply vents, and you will not feel air being blown out of them. Ductwork for returns is typically found in unconditioned spaces of your home, such as attics, inside walls or under floors, and even crawlspaces and basements. These spaces are often unreachable for contractors to fix or seal after the home is built without the need to demo and renovate.
Why It’s Important to Seal Air Return Ducts
Most people assume that furnace filters are enough to collect the average amount of dust being circulated inside their home, but a leaky return will cause you to replace filters at a faster rate and if left in too long can put strain on your system. An unsealed air return duct system not only sucks in dirt, dust, allergens, smelly odors, and other pollutants from attics, crawlspaces, and interior walls, but it also brings in humidity from those very same spaces. The introduction of humidity into the ductwork causes comfort issues, and can also lead to mold growth. Sealing your return ducts eliminates the threat of moisture and mold as well as block out all those pollutants from being introduced into your home and being recycled over and over again every day.

A Surprising Cure For A Persistent Health Problem
This homeowner had been plagued with health issues for 5 years, including a persistent rash on her face that doctors couldn’t either explain or cure.
