Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.

AfterAir Duct Cleaning Company in Ilchester, MD
Full-system air duct cleaning in Ilchester typically runs $450 – $850 for a single-family home, with most jobs scheduled within a few business days. We’re Hollis Air Duct Cleaning, and we’ve built our work around the reality of Ilchester’s housing stock: post-WWII homes with original galvanized ductwork, humid summers that breed mold, and shoulder seasons that pull pollen deep into undersized systems. Our crews arrive uniformed, price every job in writing before touching equipment, and back the work with our 365-Day Done Right Promise. Call (361) 326-5060 for a free estimate.
Why Ilchester Homes Are Different
Ilchester’s mid-century homes were built with ductwork sized for gravity furnaces, not the forced-air systems many homeowners run today. That mismatch means narrower ducts move air faster, pulling more debris past filters and depositing it in elbows and trunk lines where modern systems would have cleared it through.
The region’s humid subtropical climate compounds the problem. Hot, muggy summers and mild winters create ideal conditions for mold and dust-mite allergens inside those undersized ducts. Spring and fall pollen surges pull additional allergens into systems that already struggle with adequate airflow. Most duct cleaning companies in the area focus on newer construction with standard flex-duct layouts, leaving Ilchester’s older homes underserved.
In Ilchester’s older neighborhoods, original ductwork often runs through uninsulated crawlspaces or attics. Temperature swings in those spaces cause condensation on metal trunk lines, leading to rust and degraded air quality that homeowners mistake for normal aging. We’ve found rust holes in galvanized mains that have been blowing attic fiberglass into bedrooms for years without anyone tracing the source.
Our Main Ilchester Services
Ilchester homeowners call us most often for three jobs, each with its own page and pricing detail below.
Air Duct Cleaning in Ilchester
We clean full supply and return systems using Rotobrush rotary brush systems and Nikro negative-air machines. In Ilchester, this means dislodging decades of compacted debris from narrow galvanized mains, then extracting it under controlled suction so nothing settles back into the house. We inspect trunk lines for rust damage common in crawlspace runs and flag any breaches we find. Air Duct Cleaning in Ilchester covers full pricing and what the visit includes.
Dryer Vent Cleaning in Ilchester
Dryer vent cleaning in Ilchester addresses a fire risk that builds faster than most homeowners expect. Lint accumulation restricts airflow, overheating the dryer and backing moisture into laundry rooms. Many Ilchester homes have longer vent runs through finished basements or exterior walls where blockages hide from view. We clear the full run from dryer to termination and verify airflow with a meter before leaving. Dryer Vent Cleaning in Ilchester has full details.
Duct Sealing in Ilchester
Duct sealing closes the leaks that Ilchester’s temperature-swung crawlspace and attic runs develop over decades. We apply mastic sealant and mechanical fasteners at joints, then pressure-test the system to confirm sealed performance. For homes with original galvanized branch lines, sealing often improves delivered airflow more than homeowners expect, since they’ve been losing conditioned air to the attic for years. Duct Sealing in Ilchester explains the full process.
