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.
Fast, Reliable Air Duct Cleaning Across Severna Park
Air duct cleaning in Severna Park typically runs $350 – $650 for a full residential system, with most jobs completed in a single visit. We dispatch crews from our Baltimore office to Severna Park daily, and we know the difference between a 1960s rancher in Round Bay with original sheet-metal ductwork and a tight colonial off Ritchie Highway with flex runs in the attic. That local knowledge changes what we bring, how we price it, and what we fix while we’re inside your system. Call (361) 326-5060 for a free written estimate before any work starts.
Why Hollis Air Duct Cleaning Is Severna Park’s Preferred Air Duct Cleaning Company
We’ve been part of the Garrison Partners family since 2004, and our Air Duct Cleaning crews have worked enough Severna Park homes to know the patterns. Olde Severna Park homeowners call us when they smell mildew at the registers after a humid August. Buyers in Shipleys Choice want a video inspection before closing to confirm the flex duct wasn’t crushed during the basement finish. Property managers near Chartwell need documented before-and-after photos for their files.
Our technicians are background-checked, uniformed, and expected to operate by The Garrison Code: arrive inside the quoted window, price in writing before touching equipment, complete the job by the book, and leave the site clean. Every job carries our 365-Day Done Right Promise in writing. If the work fails within a year, we return and make it right at no charge, including a free second visit. Phones are answered by a live person 24 hours a day, 7 days a week. No voicemail loops. No callback queues.
HVAC Duct Cleaning in Severna Park
HVAC Duct Cleaning in Severna Park means source removal of dust, pollen, microbial growth, and construction debris from the complete forced-air system, not just wiping the vent covers. Because Severna Park sits on the tidal Severn River and Chesapeake Bay, year-round high humidity pushes moisture into crawlspace and basement duct runs where cooler metal surfaces condense. That standing water breeds mildew. A proper HVAC duct cleaning here requires agitation tools under negative pressure, HEPA filtration, and attention to the air handler, blower motor, and coil where humidity condenses first.
For a typical Severna Park single-family home, HVAC duct cleaning runs $350 – $550 for a standard system up to about 2,500 square feet. Larger homes, finished basements with extended trunk lines, or systems with significant microbial growth may reach $650. We price by the system, not by the vent, and the written quote is fixed before we start.
Source Removal vs. Fogging
We use Rotobrush rotary brush systems and Nikro negative-air machines to physically dislodge and extract contamination. Fogging a sanitizer into damp ductwork without removing the moisture source is a temporary cover-up. In Severna Park’s river communities, the moisture returns within weeks and the mildew regrows.
Air Handler and Coil Attention
Cleaning only the supply and return ducts while ignoring the air handler is incomplete work in this climate. Our crews inspect and clean the blower assembly and evaporator coil where Severna Park’s humidity loads concentrate, because a dirty coil re-contaminates clean ducts in days.
Vent Cleaning in Severna Park
Vent Cleaning in Severna Park addresses the supply and return registers, grilles, and the short boot connections where household dust, pet hair, and pollen accumulate fastest. The fall leaf and pollen load in Anne Arundel County is substantial, and return ducts near wooded lots pull that debris straight into the system. Vent cleaning is often the entry point homeowners notice first, clogged bathroom vents or dusty bedroom registers, but it should be evaluated as part of the full system, not sold as a standalone cosmetic wipe.
Standalone vent cleaning in Severna Park runs $150 – $250 for register and boot cleaning only. We recommend this only when the main trunk lines were recently serviced and the issue is isolated. More commonly, vent cleaning is included in a full system service at the $350 – $550 range.
Register and Boot Detailing
We remove each register, clean the boot cavity behind it, and inspect for crushed flex duct or disconnected joints. In newer Severna Park homes with finished basements, we’ve found boots buried in drywall with no access panel, a problem we flag before quoting.
Return Vent Load
Return vents pull unfiltered air from your home and load up fastest. In homes near the Severn River with open windows in spring, we’ve pulled pounds of pollen and leaf detritus from single large return grilles. Cleaning these without addressing the filter strategy upstream is temporary.
Trusted Brands We Service in Severna Park
Our equipment roster includes Rotobrush rotary brush systems for mechanical agitation, Nikro negative-air machines for controlled extraction, and filtration products from Honeywell, Aprilaire, Abatement Technologies, and Guardsman. We stock Aprilaire media filters and Guardsman replacement pads locally, so Severna Park homeowners don’t wait on shipped parts when a filter change is part of the service. For tight newer homes off Ritchie Highway, we carry a range of MERV ratings and can recommend the correct balance between particle capture and airflow, because the wrong filter in a high-static system drives condensation inside the duct instead of preventing it.
Common Air Duct Cleaning Problems We See in Severna Park Homes
- Standing water in crawlspace runs near the Severn. In Round Bay and Manhattan Beach, original 1950s-60s rectangular metal ducts with torn external insulation allow humid river air to condense on cool metal. We routinely find standing water and black mildew in the last eight to ten feet of run closest to the water.
- Crushed flex duct in finished basements. In Shipleys Choice and Chartwell, 1980s-90s colonials with later basement finishes often have flex duct compressed between joists or pinched by added framing, choking airflow and creating dead zones where humidity pools.
- Wrong filter starving airflow in tight homes. Newer colonials off Ritchie Highway with high-efficiency HVAC systems get fitted with filters too dense for the static pressure design. The system runs longer, cools unevenly, and condensate forms inside ductwork that should stay dry.
- Sanitizer fogging without source removal. Homeowners who paid for “duct sanitizing” in river communities call us months later when the musty smell returns. Fogging does not remove the water source or replace failed insulation, so the mildew simply regrows on the damp surface.

FAQs About Air Duct Cleaning in Severna Park
Yes, Severna Park’s heavy spring pollen and fall leaf debris can accelerate return duct loading, especially in wooded neighborhoods like Round Bay and Olde Severna Park. We recommend inspection every three to five years for most homes, but homes with chronic allergy issues, multiple pets, or open-window habits may benefit from every two to three years. Call (361) 326-5060 and we’ll assess your specific system.
A full residential system in Severna Park typically costs $350 – $550, with larger or more complex jobs reaching $650. We price per system, not per vent, and the written quote is fixed before work begins. Call (361) 326-5060 for a free estimate.
Low teaser quotes often use per-vent pricing that balloons once the technician is inside, or they sell fogging “sanitizing” without actual source removal. In Severna Park’s humid river communities, fogging without fixing the moisture source is worthless. We quote the complete job, in writing, before we start.
We provide before-and-after photos from our video inspection, documented on your invoice. You see what was in your ducts, what we removed, and the condition after service. The 365-Day Done Right Promise covers you if anything fails within a year.
Most Severna Park homes need full duct cleaning every three to five years. Homes near the water with chronic humidity issues, or homes with original 1950s-70s ductwork and failing insulation, may need more frequent inspection and targeted remediation. We do not upsell annual cleanings that aren’t justified.
