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.

Air duct cleaning in Ilchester, MD typically costs $350 – $650 for a whole-house residential system, and most jobs are scheduled within a few days of your call. Hollis Air Duct Cleaning has been part of the Garrison Partners family since 2004, and our Air Duct Cleaning crews serve Ilchester from our Baltimore office. We know the post-WWII ranches off Montgomery Road, the 1970s townhomes near Ilchester Landing, and the original duct systems that came with them. Our phones are answered by a live person 24 hours a day, 7 days a week at (361) 326-5060.
Ilchester’s housing stock is different from the new construction dominating Howard County. Most homes here were built between 1945 and 1980 with galvanized steel or early flex duct sized for gravity furnaces, not modern forced-air systems. That matters because standard duct cleaning, the kind designed for newer homes, often misses the real problems: rusted trunk lines in crawlspaces, disconnected joints dumping air into attics, and decades of accumulated debris that simple vacuuming won’t touch. We price every job in writing before we start, and every job carries our 365-Day Done Right Promise.
Why Hollis Air Duct Cleaning Is Ilchester’s Preferred Air Duct Cleaning Company
We’ve built our reputation in Ilchester by showing up when we said we would and doing what we promised. Our technicians are background-checked, uniformed, and expected to follow The Garrison Code on every job: arrive inside the quoted window, price in writing, complete the work by the book, and leave the site clean.
Our 365-Day Done Right Promise covers every repair and sealing job we perform. If the work fails within a year, we return and make it right at no charge, including a free second visit. That guarantee is backed in writing on every invoice, not offered verbally and forgotten.
Dispatch and scheduling for Ilchester are coordinated from our Baltimore office, which means we’re familiar with local permitting requirements and can navigate to neighborhoods from Hillcrest to the townhomes near Ilchester Landing without delay. Calls are answered by a live person, not a voicemail loop or callback queue.
We don’t compete on the lowest teaser price. We compete on discipline: written prices that don’t move at the door, equipment from Rotobrush and Nikro that commercial crews use, and technicians who explain what they’re doing in plain terms.
Vent Cleaning in Ilchester
Vent Cleaning in Ilchester addresses the supply and return registers where visible dust, pet hair, and pollen first enter your living space. In older Ilchester homes, we often find registers painted shut or blocked by decades of accumulation that standard vacuum attachments can’t reach. A typical vent cleaning as part of a whole-house system runs $350 – $650, with individual vent servicing available for $45 – $85 per register when done as a standalone call.
Supply Vent Deep Cleaning
Supply vents push conditioned air into your rooms, but in Ilchester’s gravity-furnace-era homes, they were often installed without proper filtration paths. We use rotary brush agitation with negative-air containment to dislodge debris, then extract it with a Nikro negative-air machine rather than blowing it back into your home.
Return Vent Restoration
Return vents pull air back to the handler, making them the primary entry point for allergens. In Ilchester’s humid climate, we’ve found mold staining on return vent covers in homes near the Patapsco River corridor where moisture levels stay elevated through summer. We remove and clean the grilles, treat the boot assembly, and document before-and-after conditions with photos.
Air Duct Repair in Ilchester
Air Duct Repair in Ilchester fixes the structural failures we find in original duct systems: rusted galvanized trunks, separated joints in crawlspaces, crushed flex runs, and gaps where mastic has dried and fallen away. Repair costs typically run $200 – $500 for joint sealing and minor reconnection, with full trunk replacement in the $1,200 – $2,800 range when rust has compromised the metal. We always inspect with a camera before quoting, so you see what we see.
Crawlspace and Attic Joint Sealing
Ilchester’s original ductwork often runs through uninsulated crawlspaces where temperature swings cause condensation and rust. We seal failed joints with mastic and mesh, not tape that will fail again in six months. This stops conditioned air from dumping into your crawlspace and prevents humid summer air from being pulled back into your system.
Flex Run Reconnection and Support
Early flex duct in Ilchester’s 1970s townhomes was often hung with inadequate support, leading to sagging, crushing, or complete disconnection from the trunk. We reconnect these runs with proper mechanical fasteners and add support straps to maintain airflow to rear bedrooms that have gone underserved for years.
Trusted Brands We Service in Ilchester
Our equipment roster includes Rotobrush rotary brush systems for agitation cleaning, Nikro negative-air machines for debris extraction, and filtration products from Honeywell, Aprilaire, and Guardsman. We stock common replacement components for these brands locally, which means faster turnaround when your Ilchester home needs a filter upgrade or a damaged section of flex duct replaced. We don’t use hardware-store vacuums or consumer-grade tools. The equipment we bring is the same gear commercial HVAC contractors specify for schools and medical facilities, adapted for residential access.
Common Air Duct Cleaning Problems We See in Ilchester Homes
- Rusted galvanized trunks in uninsulated crawlspaces. Ilchester’s post-WWII homes used steel duct that corrodes where condensation collects. We find rust scale and pinhole leaks in the Hillcrest neighborhood regularly, and vacuum-only cleaning leaves that debris in place to contaminate your air.
- Disconnected joints dumping air into attics or crawlspaces. Original mastic and tape have dried and failed after 50+ years. Homeowners notice uneven heating or cooling, but the real problem is a separated joint they can’t see without a camera.
- Crushed or sagging flex duct from the 1970s. Early flex material lacked the structural support of modern products. In Ilchester’s townhomes, we find runs that have been crushed by storage items or simply collapsed under their own weight, starving rear rooms of airflow.
- Mold and dust mite proliferation from humid summer infiltration. Ilchester’s humid subtropical climate means crawlspaces stay damp for months. Leaky ducts pull that moist air into the system, where it feeds biological growth that standard cleaning won’t address without sealing the leaks first.

Whole-house residential air duct cleaning in Ilchester runs $350 – $650 for a typical 1,500 – 2,500 square foot home with 8 – 15 registers.

FAQs About Air Duct Cleaning in Ilchester
Ilchester’s post-WWII single-family homes and 1970s townhomes were built with duct systems sized for gravity furnaces, meaning the supply and return runs are undersized for modern forced-air systems and are more prone to static pressure problems and leakage at joints. Most area duct cleaning companies focus on newer construction, leaving these original galvanized and early flex systems in Ilchester largely unserviced. Our crew was called to a 1950s single-family home in the Hillcrest neighborhood where the homeowner reported uneven heating and visible dust streaking at the registers. Using camera inspection, we found the original galvanized supply trunk running through an uninsulated crawlspace had rusted and separated at a joint, dumping heated air into the crawlspace instead of the living room. We performed source removal with agitation tools under negative pressure, sealed the failed joint with mastic and mesh, and reconnected a crushed flex run to the air handler, restoring proper airflow to the rear bedrooms. Call (361) 326-5060 for a free inspection.
Signs include uneven temperatures between rooms, visible dust streaking around registers, unexpectedly high energy bills, and musty odors when the system runs. In Ilchester specifically, homes with original ductwork through uninsulated crawlspaces or attics are at highest risk. We use video inspection to show you exactly what we find before quoting any repair. Call (361) 326-5060 to schedule a camera look.
Yes. Ilchester’s humid subtropical climate brings hot, muggy summers and mild winters, promoting mold growth and dust mite proliferation inside ductwork, while spring and fall pollen surges pull allergens into systems. Leaky ducts in older homes compound the problem by drawing moist crawlspace air directly into your airflow. Cleaning without sealing the leaks is a temporary fix at best. Call (361) 326-5060 for an assessment that addresses both.
We clean and repair ductwork connected to all major HVAC brands, and we stock filtration products from Honeywell, Aprilaire, and Guardsman for Ilchester homeowners looking to upgrade their air handling. Our equipment includes Rotobrush rotary brush systems and Nikro negative-air machines that work with any manufacturer’s duct configuration. Call (361) 326-5060 to discuss your specific system.
Cleaning alone won’t fix poor airflow caused by disconnected joints, crushed flex runs, or undersized ductwork. In Ilchester’s older homes, we find that airflow problems usually require repair or sealing in addition to source removal. We inspect with a camera first, explain what we find, and give you a written price for the complete solution before starting any work. Call (361) 326-5060 for a free estimate.
