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 Columbia, MD
Dryer vent cleaning in Columbia runs $149-$289 for a standard single-story run and $189-$349 when the vent rises through multiple floors or exits at the roof, which is common in the village townhomes built between 1967 and the 1990s. The humid Mid-Atlantic summers push humidity above 70% for weeks at a time, and that moisture condenses inside dryer vents caked with lint, turning a simple airflow problem into a mold and fire-risk problem faster than homeowners expect. Call (806) 606-6902 for a written price before any work begins, under Haven Standard Clause 1.
Why Columbia Homes Are Different
Columbia was built village by village starting in 1967, and that planned construction schedule means entire neighborhoods share the same ductwork vintage. Wilde Lake and Harper’s Choice, the first villages finished in 1967-1969, contain original flex duct and fiberglass-lined metal runs that are now 50+ years old and shedding insulation particles into living spaces. Oakland Mills and Long Reach followed shortly after with nearly identical materials, so age-related duct deterioration is predictable by village rather than scattered house by house as it is in organically developed suburbs.
The housing mix matters too. Columbia has a high proportion of multi-story townhomes where ductwork runs through interior wall chases and tight mechanical closets. Access panels are often behind finished walls or in narrow attic knee-spaces, which makes thorough cleaning and sealing measurably more labor-intensive than in a single-story ranch. And the climate adds another layer: hot humid summers followed by cold winters create frequent condensation cycles inside ducts, accelerating the organic buildup that feeds mold and mildew. In this market, annual or biennial cleaning is a maintenance decision, not an upsell.
Our Main Columbia Services
Most Columbia homeowners call CleanRun for one of two jobs: full air duct cleaning across every run in the house, or HVAC cleaning focused on the air handler, coils, and blower assembly. Both start with a written price, and both end with a documented photo record of every run.
Air Duct Cleaning in Columbia
Full-system air duct cleaning in Columbia typically runs $397-$697 for a single system under 2,500 square feet, with multi-system homes and finished basements pushing toward the higher end. In Wilde Lake and Harper’s Choice especially, crews regularly find the original mylar flex duct cracked at the inner liner, which means cleaning must be paired with a repair assessment rather than just brushing. The full breakdown of scope, local conditions, and written pricing lives on our Air Duct Cleaning in Columbia page.
HVAC Cleaning in Columbia
HVAC cleaning here means the air handler, evaporator coil, blower wheel, and condensate pan, not just the duct runs. Columbia’s summer humidity means coils here collect biological growth faster than in drier markets, and a dirty blower wheel can cut airflow enough to make the whole system work harder through July and August. Pricing, scope detail, and what the camera shows before and after are on our HVAC Cleaning in Columbia page.

BeforeAfterDryer Vent Cleaning in Columbia
Dryer vent cleaning in Columbia is the single highest-ROI maintenance call for townhome owners, because multi-story vents that exit at the roof or through a second-floor wall accumulate lint at every bend and are nearly impossible to clear with a homeowner-grade brush. The humid Mid-Atlantic air makes this worse: lint that stays damp for weeks begins to mildew, and the exhaust smells musty even when the dryer runs hot. Dryer Vent Cleaning is quoted as a written price per vent run before any work begins, and the before-and-after photos are included as standard documentation.
Dryer Vent Inspection
Signs you need it
Clothes that take two or three cycles to dry, a burning smell while the dryer runs, or a vent flap that barely opens are all signs that airflow is restricted somewhere in the run.
What it costs in Columbia
A camera-only inspection in Columbia runs $89-$149, and the camera footage is included in your written documentation regardless of whether you proceed with cleaning.
How we do it
We run a high-resolution push camera through the full vent path, mark the exact location and type of blockage, and hand you a written scope with still photos before quoting any work.
Lint Removal
Signs you need it
Visible lint building up around the dryer exterior, a musty odor in the laundry room, or dryer cycles that run long but leave clothes damp point to lint accumulation deep in the vent run.
What it costs in Columbia
Full lint removal in Columbia runs $149-$289 for a standard ground-floor vent and $189-$349 when the run climbs through multiple stories or exits through the roof.
How we do it
We use rotating head brushes and negative-pressure extraction to pull loosened lint out of the run without pushing it into the wall cavity, then photo-document the full interior.
Vent Rerouting
Signs you need it
A dryer vent that terminates in a crawlspace, garage, or interior wall violates building code and saturates your framing with moisture every single cycle.
What it costs in Columbia
Rerouting a vent to a proper exterior termination in Columbia runs $395-$795 depending on the distance and the number of wall penetrations required.
How we do it
We design the shortest compliant route to an exterior wall or roof, replace the existing run with rigid or semi-rigid duct, and reseal every connection before testing airflow.
Bird Guard Installation
Signs you need it
Nesting material or bird droppings visible at the vent exterior, or chirping sounds from the vent during spring months, mean birds have taken residence in your exhaust path.
What it costs in Columbia
Bird guard installation in Columbia runs $85-$185 including the guard, debris removal, and sealant around the exterior termination.
How we do it
We remove any nesting material, install a corrosion-resistant guard sized to your vent, and document the finished work with exterior and interior photos.
What Dryer Vent Cleaning Costs in Columbia
| Item | Typical range in Columbia |
|---|---|
| Dryer Vent Inspection | $89-$149 |
| Lint Removal | $149-$349 |
| Bird Guard Installation | $85-$185 |
Is dryer vent cleaning really necessary in Columbia’s newer villages?
Yes. River Hill and Dorsey’s Search homes are newer, but Columbia’s humidity affects every vent regardless of construction date, and lint accumulation is a function of dryer use, not home age. A vent that has never been cleaned on a five-year-old townhome can be as restricted as one on a 1970s original.
How long does dryer vent cleaning take in a Columbia townhome?
Most townhome vents in Columbia take 45 to 90 minutes on site. Roof-exit runs in multi-story units take longer because of access and ladder time. The written quote you receive before work starts reflects that access difference, not a surprise add-on.
Duct Repair & Sealing in Columbia
Duct repair and sealing in Columbia is most urgent in the original villages, where Wilde Lake and Harper’s Choice homes sit with 50-year-old flex duct that has cracked inner liners and deteriorated outer jackets. Columbia’s humid summers force condensation onto duct surfaces, and when the insulation jacket is compromised, that moisture wicks into the duct interior and accelerates mold growth while the system loses conditioned air into wall cavities. Duct Repair & Sealing work is quoted by the run and the material, and the written scope identifies exactly which sections are sealed, replaced, or insulated before any tool comes off the truck.
Duct Sealing
Signs you need it
Rooms that never reach the thermostat setpoint, visible dust streaks at register grilles, or utility bills that climb in July without a matching increase in comfort all suggest air escaping through unsealed duct joints.
What it costs in Columbia
Sealing accessible ductwork in a Columbia home runs $395-$795 per system, with complex multi-story townhome layouts landing at the higher end because of the additional access work.
How we do it
We apply mastic sealant or foil-backed tape rated for HVAC systems to every accessible joint, then run a pressure test to verify the leakage reduction before handing you the before-and-after numbers.
Flex Duct Repair
Signs you need it
Crushed or kinked flex duct visible in the attic or basement, rooms that feel starved for airflow, or a musty smell that comes and goes with the blower cycle indicate damaged flex runs.
What it costs in Columbia
Repairing or replacing a damaged flex run in Columbia runs $195-$495 per run depending on length, diameter, and whether the run is accessible without opening finished surfaces.
How we do it
We cut out the damaged section or replace the full run, match the diameter to the system design, and support the new duct with proper strapping so it cannot sag or kink again.
Duct Insulation
Signs you need it
Sweating ductwork in the summer, warm air blowing in the winter before the furnace fully fires, or visibly torn insulation jackets on exposed runs all mean the thermal barrier is failing.
What it costs in Columbia
Re-insulating accessible ductwork in Columbia runs $295-$595 per main trunk line, with additional branch runs quoted individually based on diameter and length.
How we do it
We remove the degraded jacket, inspect the duct surface for corrosion or biological growth, and wrap the run with a new insulation layer sealed at every seam and termination.
What Duct Repair & Sealing Costs in Columbia
| Item | Typical range in Columbia |
|---|---|
| Duct Sealing | $395-$795 per system |
| Flex Duct Repair | $195-$495 per run |
| Duct Insulation | $295-$595 per trunk line |
Why does duct repair cost more in Columbia townhomes?
Access is the main reason. Columbia townhomes built before 1990 often route ductwork through interior wall chases with no access panel, so reaching a failing run may require cutting and patching drywall. That labor is written into the quote before work starts, not added after.
Can you clean ducts without repairing them first?
In some cases, yes, but in the older Columbia villages a cleaning camera often reveals cracked liners that make cleaning pointless until the run is repaired. We quote both scopes separately so you see exactly what the camera showed and what each remedy costs.
Air Quality & Sanitizing in Columbia
Air quality and sanitizing in Columbia addresses a specific problem the climate creates: summer humidity above 70% drives condensation inside ducts and air handlers, and that sustained moisture is exactly what mold, bacteria, and odor-causing organisms need to colonize. Homes in the 1960s and 1970s villages are most exposed because degraded fiberglass liners hold moisture longer than smooth metal. Air Quality & Sanitizing work is quoted per system with a written scope, and the before-and-after documentation includes photos of the treated surfaces so the result is visible, not promised.
Mold Treatment
Signs you need it
A persistent musty odor that intensifies when the HVAC fan runs, visible dark staining at registers or inside accessible duct openings, or allergy symptoms that worsen at home but improve away indicate possible mold colonization.
What it costs in Columbia
Mold treatment for a single HVAC system in Columbia runs $495-$1,195 depending on the affected surface area and whether the air handler, coils, and duct runs all require treatment.
How we do it
We apply an EPA-registered antimicrobial to affected surfaces using a fogging or direct-spray method, allow the required dwell time, and photo-document the treated areas before and after.
Odor Removal
Signs you need it
Cooking, smoke, or pet odors that return within hours of airing out the home, or a stale smell that sits in the ducts even after cleaning, mean odor molecules have been absorbed into duct surfaces and insulation.
What it costs in Columbia
Whole-system odor removal in Columbia runs $295-$595 and includes treatment of the accessible duct interiors, air handler surfaces, and condensate pan.
How we do it
We identify the odor source with a camera inspection, treat affected surfaces with an odor-neutralizing agent rather than a masking fragrance, and refresh the system with a final air-wash cycle.
UV Light Installation
Signs you need it
Recurring biological growth on the evaporator coil despite regular cleaning, or a household member with respiratory sensitivity where airborne microbial load reduction is a priority.
What it costs in Columbia
UV light installation in Columbia runs $495-$895 including the lamp, mounting hardware, electrical connection, and a written explanation of the coverage zone.
How we do it
We mount a UV-C lamp in the supply plenum or above the coil, wire it to operate in sync with the blower, and verify output with a radiometer before leaving.
What Air Quality & Sanitizing Costs in Columbia
| Item | Typical range in Columbia |
|---|---|
| Mold Treatment | $495-$1,195 per system |
| Odor Removal | $295-$595 per system |
| UV Light Installation | $495-$895 |
Does sanitizing replace duct cleaning?
No. Sanitizing treats biological growth on surfaces, but it does not remove the dust, debris, and degraded insulation that feeds it. In Columbia’s older villages, we usually quote cleaning and sanitizing together, then apply the treatment after the surfaces are actually clean.
Are the products safe for my family and pets?
The EPA-registered antimicrobials we use are selected for occupied residential spaces and applied according to label dwell times and ventilation requirements. We hand you the product name and safety data sheet with your written job documentation, so there is nothing hidden in the fog.

FAQs About Air Duct Cleaning in Columbia
Most interior duct work, including cleaning, sealing, and repair, requires no HOA approval in Columbia because it does not alter exterior appearance or common elements. The exception is a roof-exit dryer vent or any exterior termination change, which may need a design review. We confirm applicable requirements before quoting that scope.
Most Columbia appointments are scheduled within one to three business days. Non-emergency cleaning and sanitizing jobs are typically available within a week, and the written quote is delivered before any work begins, so scheduling and pricing are settled in a single call.
Yes. Buyers in Columbia regularly request a camera inspection during the due-diligence period, especially for 1960s and 1970s village homes with original ductwork. You receive the footage, a written condition report, and a repair or cleaning quote in writing before closing.
