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 in Arnold, MD
Dryer vent cleaning in Arnold typically costs $95-$185 and solves a problem this peninsula makes worse than almost anywhere else in Anne Arundel County. The Broadneck Peninsula’s water-on-three-sides geography keeps relative humidity elevated from June through September, and that moisture saturates lint inside vent runs faster than in drier inland neighborhoods. If you own a 1960s or 1970s home in Cape St. Claire or nearby Arnold subdivisions, your vent line is likely original, undersized, and overdue for a camera inspection. Call (806) 606-6902 for a written price before any equipment comes off the truck.
Why Arnold Homes Are Different
Arnold sits on the Broadneck Peninsula, pinched between the Magothy River to the north and the Severn River and Chesapeake Bay corridor to the south. That geography does something measurable to the air. Technicians who work Arnold and then drive ten minutes west into Severna Park notice the difference immediately: the peninsula holds bay moisture longer, particularly from June through September, and that moisture works its way into every duct run, vent line, and crawl space in sight.
The housing stock makes it worse. Arnold developed intensively through the 1960s and 1970s; Cape St. Claire and surrounding communities are full of ranch-style, split-level, and early colonial homes whose original sheet-metal and early flex-duct systems are now 40 to 60 years old. Many of those builds put supply and return lines in crawl spaces directly above damp ground. When crawl-space duct runs sit close to wet soil and the air outside never really dries out, condensation forms inside the ducts themselves. The result is biological growth that shows up on registers long before homeowners notice a change in how the air feels or smells.
CleanRun crews working Cape St. Claire repeatedly find the same thing: flex-duct runs in 1960s ranch homes with compromised vapor barriers and condensation damage at the duct-boot connections. That pattern is driven by the peninsula’s ground moisture and bay humidity. It is not something you see in drier inland zip codes, and it changes how ductwork should be inspected, cleaned, and sealed here.
Our Main Arnold Services
Arnold homeowners call us most often for two jobs: full air duct cleaning and complete HVAC system cleaning. Both are documented with before-and-after photos of every duct run.
Air Duct Cleaning in Arnold
Air duct cleaning in Arnold is a bigger job than it is ten minutes west. The sustained humidity on the Broadneck Peninsula accelerates mold and microbial colonization inside duct interiors, so what starts as a dust problem becomes a biological one faster than regional averages. Our crews use negative-pressure extraction equipment from Rotobrush and Nikro to pull debris out rather than push it around, and every run is photographed before and after. You get the photo record as part of the standard job file. See the full scope at Air Duct Cleaning in Arnold.
HVAC Cleaning in Arnold
HVAC cleaning in Arnold means cleaning the blower assembly, evaporator coil, and condensate pan, not just the ducts running to your registers. In a peninsula microclimate this humid, the coil is usually where biological growth concentrates first, because it stays cold and wet through the whole cooling season. We inspect the plenum and coil cabinet, clean what a camera can see, and document it all. See what the job covers at HVAC Cleaning in Arnold.

BeforeAfterDryer Vent Cleaning in Arnold
Dryer vent cleaning in Arnold matters more than it does inland because the peninsula’s sustained humidity turns ordinary lint accumulation into a faster-moving fire risk and a slower-drying laundry problem at the same time. Homes in Cape St. Claire and the surrounding 1960s-era subdivisions frequently run original vent lines through crawl spaces and exterior walls where moisture collects at every bend. A clogged vent here does not just make the dryer work harder; it gives damp lint a place to sit and compact until airflow drops to almost nothing. Dryer Vent Cleaning is the service that clears that line and photographs the result.
Dryer Vent Inspection
Signs you need it
Your clothes take two cycles to dry, the laundry room feels humid after a load, or the dryer’s exterior vent flap barely moves when the machine runs.
What it costs in Arnold
A camera inspection of your dryer vent line in Arnold typically runs $95-$185, with the written price set before we open the wall or roof access.
How we do it
We run a camera down the full vent run from the dryer connection to the exterior termination, record what we find, and show you the footage before pricing any cleaning or repair work.
Vent Cleaning
Signs you need it
You can see lint built up on the exterior vent hood, the dryer is hot to the touch after a cycle, or the room smells like burnt dust.
What it costs in Arnold
Full vent cleaning in Arnold typically runs $95-$185 depending on run length, access point, and how old the original installation is.
How we do it
We use a rotary brush and HEPA-filtered vacuum from the exterior vent inward, then verify airflow with a vane anemometer and photograph the cleared run.
Lint Removal
Signs you need it
The dryer’s lint trap is clean but the machine still takes forever, which means the clog is farther down the line and the trap is not catching it.
What it costs in Arnold
Standalone lint removal in Arnold is priced inside the same $95-$185 vent cleaning range once the camera shows where the blockage sits.
How we do it
We locate the compacted lint with the camera, dislodge it with a rotating brush line, and pull the debris out under negative pressure rather than blowing it into the crawl space.
Vent Rerouting
Signs you need it
The dryer vent currently terminates under the house, in the crawl space, or within three feet of an operable window or door, which most current codes prohibit.
What it costs in Arnold
Rerouting a vent line in Arnold typically runs $250-$500 depending on the new termination point and how much of the old run can be left in place.
How we do it
We plan the shortest code-compliant route to an exterior wall or roof cap, replace the old run with smooth-wall rigid duct, and document the new installation with photos.
Bird Guard Installation
Signs you need it
You have seen birds entering or nesting near the exterior vent termination, or the existing vent cover is missing and the line sits open to the bay air.
What it costs in Arnold
Adding a bird guard in Arnold typically runs $95-$185, including the guard itself and the fastening hardware appropriate for your exterior surface.
How we do it
We install a stainless steel guard over the vent termination that blocks bird entry while maintaining full exhaust airflow, then photograph the finished exterior.
What Dryer Vent Cleaning Costs in Arnold
| Item | Typical range in Arnold |
|---|---|
| Camera inspection | $95-$185 |
| Vent cleaning / lint removal | $95-$185 |
| Vent rerouting | $250-$500 |
How often should a dryer vent be cleaned in Arnold?
Every 12 to 18 months for most Arnold homes. The peninsula’s humidity packs lint tighter, so a vent that an inland household could leave for two years often needs attention sooner here. Call (806) 606-6902 to schedule.
Why does my dryer take so long in an Arnold home?
Usually because the vent run is original to a 1960s or 1970s build and has accumulated compacted lint at the first elbow or the exterior hood. The camera inspection shows exactly where the restriction is. Call (806) 606-6902 for a written price.
Duct Repair & Sealing in Arnold
Duct repair and sealing in Arnold is the fix for what the peninsula’s ground moisture does to aging ductwork. Homes built in the 1960s and 1970s around Cape St. Claire often have crawl-space flex-duct runs with compromised vapor barriers and condensation damage at the duct-boot connections, and those leaks pull damp crawl-space air into the supply stream. Sealing the runs and repairing the boots is the difference between a clean system and one that re-contaminates itself. Duct Repair & Sealing is the service that puts a written price on the fix.
Duct Sealing
Signs you need it
Some rooms stay hot or cold no matter how the thermostat is set, or you can feel air moving around duct connections in the crawl space.
What it costs in Arnold
Duct sealing in Arnold typically runs $1,250-$3,100 depending on the number of runs, access difficulty, and how much of the system is in the crawl space.
How we do it
We locate leaks with a pressure test or smoke pencil, seal accessible joints with mastic, and document every sealed connection in the before-and-after photo record.
Flex Duct Repair
Signs you need it
The flex duct in your crawl space has visible tears, sags between supports, or condensation staining at the connections where it meets the boots.
What it costs in Arnold
Flex duct repair in Arnold typically runs $1,250-$2,500 for localized damage; full replacement of a long run can push toward the top of that range.
How we do it
We cut out the damaged section, replace it with properly sized and supported flex duct, reconnect the boots, and photograph the repair.
Metal Duct Repair
Signs you need it
Sheet-metal ducts in a 1960s Arnold home are rusted through at the seams or crushed from years in a damp crawl space.
What it costs in Arnold
Metal duct repair in Arnold typically runs $1,250-$3,100 depending on the extent of corrosion and whether sections need full replacement.
How we do it
We remove the rusted or crushed section, replace it with matching-gauge metal duct, seal all seams with mastic, and photograph the finished run.
Duct Insulation
Signs you need it
The duct surfaces in your crawl space sweat during the summer, or the insulation wrap has peeled away and left bare metal exposed to the peninsula’s damp air.
What it costs in Arnold
Duct insulation in Arnold typically runs $1,250-$3,100 depending on the linear feet being re-wrapped and whether the old insulation requires removal first.
How we do it
We strip failed insulation, seal the duct surface, wrap with the appropriate R-value insulation for a damp crawl-space environment, and document the finished work.
Mastic Sealant
Signs you need it
The existing duct tape at your duct joints has dried, peeled, or failed, which is what happens to conventional tape in humid crawl spaces.
What it costs in Arnold
Mastic sealing in Arnold is priced inside the $1,250-$3,100 duct sealing range based on the number of joints we can access and seal.
How we do it
We brush mastic sealant onto every accessible joint, collar, and boot connection, then let it cure to a durable seal that does not peel like tape.
What Duct Repair & Sealing Costs in Arnold
| Item | Typical range in Arnold |
|---|---|
| Duct sealing | $1,250-$3,100 |
| Flex duct repair | $1,250-$2,500 |
| Metal duct repair | $1,250-$3,100 |
Why do my ducts sweat in my Arnold crawl space?
Because the Broadneck Peninsula’s ground moisture and bay humidity keep crawl-space air damp through the summer, and uninsulated or under-insulated duct surfaces condense moisture. Sealing and insulating the runs stops the sweating. Call (806) 606-6902 for a written scope.
Can you fix ducts without replacing the whole system?
Most of the time, yes. If the sheet metal or flex runs are structurally sound, we seal joints, repair damaged sections, and re-insulate rather than replace everything. The camera shows what is actually needed. Call (806) 606-6902.
Air Quality & Sanitizing in Arnold
Air quality and sanitizing in Arnold is the direct response to what this peninsula does to duct interiors. The sustained humidity on the Broadneck Peninsula accelerates mold and microbial colonization inside ductwork, and in 40-to-60-year-old ranch and split-level homes with crawl-space runs, the duct interiors often show visible mold on registers well before homeowners notice any air quality change. Cleaning the ducts helps, but sanitizing the surfaces is what interrupts the regrowth cycle. Air Quality & Sanitizing is the service that treats the problem at the surface level.
Mold Treatment
Signs you need it
You see dark staining on registers or return grilles, or the air from the vents smells musty when the blower kicks on.
What it costs in Arnold
Mold treatment in Arnold typically runs $450-$900 depending on the number of runs treated and the square footage of duct surface.
How we do it
We apply an EPA-registered antimicrobial to accessible duct surfaces after mechanical cleaning, then photograph the treated areas for the job record.
Bacteria Sanitizing
Signs you need it
Household illnesses linger or recur, or the HVAC system has moved moisture through the ducts and the air smells stale even after cleaning.
What it costs in Arnold
Bacteria sanitizing in Arnold typically runs $450-$900 for a full-system treatment of supply and return runs.
How we do it
We fog the duct system with a sanitizing agent after mechanical cleaning, giving the product dwell time on surfaces before the system runs again.
Odor Removal
Signs you need it
A smell persists after the ducts have been cleaned, usually from biological growth or residue absorbed into the duct lining or insulation.
What it costs in Arnold
Odor removal in Arnold typically runs $450-$900 as a standalone treatment, with the written price set before any work begins.
How we do it
We identify the odor source with a camera, clean or replace the affected material, and treat the duct surfaces to neutralize what remains.
UV Light Installation
Signs you need it
Your evaporator coil grows mold every cooling season despite regular cleaning, which is a common pattern in Arnold’s humid peninsula air.
What it costs in Arnold
UV light installation in Arnold typically runs $600-$1,200 depending on the unit and the mounting location on the coil or plenum.
How we do it
We mount a UV-C lamp at the evaporator coil, wire it to the system, and verify the lamp operates before leaving.
Air Purifier Install
Signs you need it
You want whole-house filtration beyond a standard filter, or household members react to airborne particles the current setup cannot capture.
What it costs in Arnold
Air purifier installation in Arnold typically runs $600-$1,200 for a duct-mounted unit wired into the blower circuit.
How we do it
We install the purifier in the supply plenum, wire it to run with the blower, and confirm airflow and electrical connections before testing the system.
What Air Quality & Sanitizing Costs in Arnold
| Item | Typical range in Arnold |
|---|---|
| Mold treatment | $450-$900 |
| Bacteria sanitizing | $450-$900 |
| UV light installation | $600-$1,200 |
Does air duct sanitizing actually work in Arnold’s humidity?
It works when the underlying moisture source is also addressed. Sanitizing kills what is on the duct surfaces; sealing and insulation stop the condensation that lets it regrow. Call (806) 606-6902 for a combined scope.
Will sanitizing get rid of the musty smell in my Arnold home?
Usually yes, when the smell comes from duct surfaces or the coil. If the odor source is saturated insulation or standing moisture, that material needs replacement first. The camera shows which situation you have. Call (806) 606-6902.

What pushes a price toward the top of these ranges in Arnold is the crawl space. When supply and return runs sit in a damp crawl space under a 1960s ranch in Cape St. Claire, access is harder, runs are longer, and the repair scope often includes multiple failed connections rather than one. That is why we write the price before work starts: you see the number, you agree to the number, and that number does not change mid-job.
