AfterAir Duct Cleaning in Severn, MD
Dryer vent cleaning in Severn runs $130-$240 for most single-family homes, with the job taking about an hour and leaving you with a written photo record of every inch of the run. Severn’s housing stock changes that math in one specific way: homes here were largely built between the late 1960s and 1990s around Fort Meade’s workforce expansion, and many still carry their original or early-replacement sheet metal and flex duct systems with joints that have never been sealed correctly. When a vent hasn’t been cleaned across multiple PCS cycles and the previous occupants treated the house as a two-year assignment rather than a long-term investment, we routinely pull out compacted lint columns that a standard home inspector’s flashlight never reaches. Call (806) 606-6902 for a written price before anyone touches a single panel.
Why Severn Homes Are Different
Severn wraps around the eastern perimeter of Fort Meade, and that shape dictates what we find inside its ductwork. The housing stock is mostly colonial and split-level single-family homes plus townhome communities built from the late 1960s through the 1990s, and the original sheet metal and flex duct systems in those homes are now 30 to 50 years old. Many have never been professionally cleaned. Degraded flex duct insulation, poorly sealed joint connections, and accumulated debris sit inside systems that have cycled through multiple military tenants on PCS orders, often with no maintenance records at all. Incoming service members and contractors frequently request cleaning before occupying a property whose history they cannot verify.
The climate compounds the problem. Severn sits in the humid mid-Atlantic corridor where summer humidity routinely exceeds 80%, keeping HVAC systems running nearly continuously from June through September. That creates persistent condensation conditions inside ductwork that favor mold and mildew growth, particularly in the many crawl-space-ducted homes around older subdivisions near MD-174 where ground moisture adds another layer of humidity. We have opened plenums in Severn homes and found 20-plus years of pet dander, dust, and mold that no previous occupant ever addressed because the home was a short-term assignment, not a long-term investment.
Our Main Severn Services
Two services account for most of the calls we take from Severn homeowners, and both are linked below to their dedicated Severn pages.
Air Duct Cleaning in Severn
Whole-system air duct cleaning addresses the accumulated debris, dust, and biological growth inside the supply and return runs, plenums, and registers that serve every room. In Severn’s 30-to-50-year-old colonial and split-level homes, that debris is often decades deep and has never been touched. Full details on what we find, what it costs, and how the photo record works are on the Air Duct Cleaning in Severn page.
HVAC Cleaning in Severn
HVAC cleaning goes beyond the ductwork itself to the blower motor, evaporator coil, drain pan, and other components inside the air handler that circulate conditioned air through the home. Severn’s humid summers mean coils here accumulate biological growth faster than in drier climates, and a dirty coil reduces airflow and system efficiency. Full details are on the HVAC Cleaning in Severn page.

BeforeAfterDryer Vent Cleaning in Severn
Dryer vent cleaning in Severn is the service we recommend first for most homes built before 2000, because the original vent runs in these colonials and split-levels are often long, multi-elbow paths that trap lint far more aggressively than the short, straight runs in newer construction. When a vent has gone years without cleaning and the home has passed through several PCS tenants, the lint accumulation inside the run is compacted by heat and moisture into a solid column that reduces airflow, forces the dryer to run longer cycles, and creates a fire hazard. We document every foot of the run before and after with a camera, so you see exactly what was removed rather than taking our word for it. That documentation matters in Severn’s high-turnover market, where an incoming buyer or a landlord wants proof the vent was actually cleaned. Read more about our approach on the Dryer Vent Cleaning page.
Dryer Vent Inspection
Signs you need it
Clothes take more than one full cycle to dry, the exterior vent flap doesn’t open fully during operation, or the dryer itself feels unusually hot to the touch.
What it costs in Severn
An inspection-only visit is $70, and that amount is credited toward the cost of a cleaning if we find a blockage and you approve the work the same day.
How we do it
We run a camera through the entire vent run from both ends, checking each elbow and joint for lint accumulation, airflow restriction, and any disconnection inside wall or ceiling cavities.
Lint Removal
Signs you need it
The dryer takes longer than it should, the lint screen fills faster than it used to, or you can see lint protruding from the exterior vent hood.
What it costs in Severn
Full lint removal from a standard residential vent run in Severn runs $130-$240, depending on run length, number of elbows, and how compacted the accumulation has become.
How we do it
We connect a professional HEPA-filtered negative-pressure extraction system to the vent, then run rotating brushes through the full length to break free compacted lint and pull it out to the exterior.
Bird Guard Installation
Signs you need it
You hear birds or rustling inside the vent, see nesting material protruding from the exterior hood, or notice the vent flap is jammed open.
What it costs in Severn
Installing a galvanized steel bird guard and protective cage over the exterior termination runs $165-$225 in Severn.
How we do it
We inspect the full run first to confirm no live nesting is present, then secure a screened guard that keeps birds and rodents out while maintaining proper airflow.
What Dryer Vent Cleaning Costs in Severn
| Item | Typical range in Severn |
|---|---|
| Inspection-only (credited toward cleaning) | $70 |
| Standard lint removal, single-family home | $130-$240 |
| Bird guard and exterior cage installation | $165-$225 |
How often should a dryer vent be cleaned in Severn?
Every 12 months for a household of two or more that runs the dryer regularly. Homes with long vent runs through crawl spaces or multiple elbows should consider every 9 months due to Severn’s humidity.
Can you clean a dryer vent that runs through the roof in Severn?
Yes. Roof-terminated vents are common in Severn’s older colonials and split-levels, and we clean them from the interior using the same extraction equipment, so roof access is rarely needed. Call (806) 606-6902 and we’ll tell you what your specific run will cost.
Duct Repair & Sealing in Severn
Duct repair and sealing in Severn addresses the leaky joints, degraded flex duct, and separated connections we find in the 30-to-50-year-old systems that dominate this housing stock. Those original installations used tape and loose-fitting connectors that have been drying out and separating for decades, which means a meaningful percentage of the air you pay to heat and cool never reaches the rooms it’s intended for. Sealing those leaks, replacing failed flex sections, and insulating the runs properly keeps conditioned air inside the ducts where it belongs and out of crawl spaces and attics. Our crews photograph every joint they touch and every repair they make, so the before-and-after record is clear. See our full process on the Duct Repair & Sealing page.
Duct Sealing
Signs you need it
Some rooms are consistently warmer in summer or colder in winter than the rest of the house, or your utility bills stay high even after normal HVAC maintenance.
What it costs in Severn
Sealing accessible duct joints and connections runs $200-$500 in Severn, depending on how many joints are accessible and how many need mastic application.
How we do it
We locate leaks using a pressure test, then apply mastic sealant and aluminum tape to each leaking joint and connection to create a permanent, airtight seal.
Flex Duct Repair
Signs you need it
You see crushed, kinked, or sagging flex duct in the attic or crawl space, or the outer jacket is torn and the inner liner is visible.
What it costs in Severn
Repairing or replacing a damaged flex duct section in Severn runs $150-$300 per section, including the new duct, connections, and sealing.
How we do it
We remove the damaged section, install new insulted flex duct to manufacturer specification, and seal both connections with mastic before re-insulating.
Duct Insulation
Signs you need it
Visible condensation on duct surfaces during humid summer days, or the existing insulation has separated, compressed, or fallen away.
What it costs in Severn
Insulating accessible duct runs in a Severn crawl space or attic runs $3-$6 per linear foot, with a typical whole-home project at $500-$1,200.
How we do it
We remove degraded insulation, clean the duct surface, and wrap the run in new R-6 or R-8 insulation with vapor barrier, sealing seams with tape.
What Duct Repair & Sealing Costs in Severn
| Item | Typical range in Severn |
|---|---|
| Sealing accessible duct joints | $200-$500 |
| Flex duct section repair or replacement | $150-$300 per section |
| Insulating accessible duct runs | $3-$6 per linear foot |
How much air do leaky ducts actually lose in Severn homes?
Our pressure testing in Severn’s older colonials and split-levels routinely shows 20-30% leakage, meaning the system is conditioning crawl space or attic air instead of living space. Sealing brings that leakage down to under 5%.
Do you have to remove drywall to seal ducts in Severn?
No. We seal from the inside of the duct where accessible, using mastic and tape applied through existing access points, registers, and plenum openings. Call (806) 606-6902 for a written price on your system.
Air Quality & Sanitizing in Severn
Air quality and sanitizing in Severn deals with what grows inside ductwork that runs through humid crawl spaces and attics during a summer season that keeps systems running nearly nonstop from June through September. Condensation inside those cool ducts creates exactly the conditions mold, bacteria, and odor-causing organisms need to establish themselves, and once they’re embedded in the duct lining and insulation, they recirculate through the home every time the blower runs. The homes we see around Fort Meade change hands frequently, and an incoming family often wants the air verified clean before they move furniture in. We apply EPA-registered antimicrobials and install whole-home purification equipment where the problem is persistent rather than a one-time issue. Full details are on the Air Quality & Sanitizing page.
Odor Removal
Signs you need it
Musty, stale, or pet odors return consistently when the HVAC system runs, even after the home has been cleaned and aired out.
What it costs in Severn
Whole-system odor treatment in Severn runs $350-$600, depending on system size and the number of return and supply runs.
How we do it
We clean the source surfaces first, then fog an EPA-registered deodorizer through the duct system to reach the full interior of every run and plenum.
UV Light Installation
Signs you need it
Mold or mildew keeps returning to the coil or drain pan despite repeated cleaning, or anyone in the home has persistent respiratory irritation.
What it costs in Severn
Supplying and installing a UV light system at the coil in Severn runs $750-$1,200, including the unit, mounting, and electrical connection.
How we do it
We mount a UV-C lamp inside the air handler facing the evaporator coil and drain pan, wired so it operates whenever the system’s blower runs.
Air Purifier Install
Signs you need it
Household members experience allergy or asthma symptoms that are worse at home than elsewhere, or dust accumulates quickly on surfaces throughout the house.
What it costs in Severn
Installing a Honeywell or Aprilaire whole-home air purifier in Severn runs $900-$1,800, depending on the model and the configuration of your air handler.
How we do it
We install the purifier in the supply plenum or return duct so every cubic foot of air moving through the system passes the filtration media.
What Air Quality & Sanitizing Costs in Severn
| Item | Typical range in Severn |
|---|---|
| Whole-system odor treatment | $350-$600 |
| UV light installation at coil | $750-$1,200 |
| Whole-home air purifier installation | $900-$1,800 |
Does duct sanitizing actually kill mold in Severn homes?
An EPA-registered antimicrobial applied to a cleaned duct surface kills active mold and inhibits regrowth, but it won’t remove the underlying moisture source. That’s why we identify and address the humidity entry point as part of the job.
How long does odor removal last in a Severn crawl-space home?
When the odor source is removed and the duct interior is treated, results typically last one to two years. Persistent crawl-space moisture may require additional sealing or insulation work. Call (806) 606-6902 to discuss your home’s specifics.

No. Duct cleaning, dryer vent cleaning, duct sealing, and air quality work is all interior or existing-exterior work that no HOA in Severn requires approval for. If your townhome shares a wall, we’ll coordinate exterior vent access to avoid disturbing neighbors.
Older systems often have narrower registers, tighter access points, and original sheet metal that requires gentler brush heads and smaller cameras than newer flex-duct systems. Our equipment is sized for these homes specifically, which is one reason we quote differently for older construction.
