Aeroseal FAQs: Health, Clean Air, & Allergies

Traditional air duct cleaning only temporarily removes “legacy dust.” If your ductwork is not sealed, your system acts like a vacuum, pulling in attic insulation, mold spores, and basement dust through hidden leaks. Without sealing these leaks, having your ducts cleaned is like washing your car with the windows rolled down.

It may be surprising, but a standard six-room home generates up to 40 pounds of biological dust, pet dander, and debris every year. Operating at high speeds, your residential blower turns this settled debris into airborne particles—recirculating them throughout your home five to seven times a day.

Unsealed return ducts pull outdoor allergens (like tree and ragweed pollen) and indoor irritants (like dust mites) from unconditioned spaces directly into your living areas, bypassing your system’s filter. Aeroseal builds a permanent health barrier by sealing these hidden leaks from the inside out, drastically reducing allergy and asthma triggers.

Yes. In humid climates, leaky return ducts pull hot, moist air from crawlspaces and attics into your system. This causes condensation, musty odors (often known as “Old House Smell”), and can even promote mold growth inside your ducts. Sealing these leaks eliminates moisture intrusions at the source.

It is our comprehensive, health-first transformation package. The process involves three steps: The Clean (removing the legacy dust), The Seal (using Aeroseal to permanently lock the outside air out of your inside air), and The Shield (installing a hospital-grade filter upgrade).

We don’t want you to guess. We provide Before and After Indoor Air Quality (IAQ) testing, giving you a computerized “Certificate of Completion” to verify your results. The service is also backed by our “Dust-Free Home Guarantee”—if you don’t notice a visible reduction in dust on your furniture, we will come back and make it right.
