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 Linthicum, MD
Hollis Air Duct Cleaning handles air duct cleaning, dryer vent cleaning, and duct sealing for Linthicum homeowners, with most whole-system jobs running between $350 and $650 depending on the home’s size and duct condition. We’re part of the Garrison Partners family, and our crews dispatch from the Baltimore office to serve Linthicum directly. The combination of aging post-war housing stock, humid summers, and proximity to BWI Airport creates duct problems here that don’t show up in newer suburbs. Call (361) 326-5060 for a free written estimate.
Why Linthicum Homes Are Different
Linthicum’s housing market is dominated by mid-century homes built between 1940 and 1970, many with original galvanized steel ductwork or early flexible duct runs that have never been properly cleaned. In neighborhoods near BWI Airport, we regularly find ductwork contaminated with elevated black soot and particulate matter from aircraft exhaust and nearby industrial activity. That residue requires specialized cleaning methods beyond what a standard rotary brush pass can handle.
The humid subtropical climate here doesn’t help. Hot, humid summers and mild winters create ideal conditions for mold and mildew growth inside duct systems, especially in homes with poor ventilation or high indoor humidity. We’ve opened ducts in Linthicum homes where the interior surface was coated with a layer of microbial growth that had been circulating spores through the house for years.
Many of these older systems also lack proper filtration or have gaps in the ductwork that pull in attic air, compounding the problem. The work here isn’t just about removing dust; it’s about addressing decades of accumulation in systems that were never designed for modern air quality standards.
Our Main Linthicum Services
Most Linthicum homeowners call us for one of three jobs. Each has its own page with full details.
Air Duct Cleaning in Linthicum
We clean the full supply and return duct network, starting with a Rotobrush rotary brush system to agitate debris off duct walls, followed by negative-air extraction using Nikro equipment to pull it out of the house. In Linthicum’s older homes, we often find galvanized steel ducts with rust scale or early flex duct that has collapsed in sections. We inspect with a camera before and after so you see what was in there. Air Duct Cleaning in Linthicum covers the full process and what to expect.
Dryer Vent Cleaning in Linthicum
Dryer vent blockages are a fire hazard, and in Linthicum’s mid-century homes the vent runs are often longer than modern code allows, with multiple elbows that trap lint. We use rotary brushes and high-velocity air tools to clear the full run from dryer to termination, then verify airflow with a meter. If your dryer takes two cycles to dry a load, the vent is likely restricted. Full details are on our Dryer Vent Cleaning in Linthicum page.
Duct Sealing in Linthicum
Leaky ducts pull unconditioned air from attics and crawl spaces, wasting energy and circulating dust and insulation particles. In Linthicum’s older homes, we commonly find disconnected joints and gaps at plenum connections that have been leaking for decades. We seal with mastic and metal-backed tape, then test with a duct blaster to verify the improvement. Our Duct Sealing in Linthicum page explains the full process.
