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 Parkville, MD
Dryer vent cleaning in Parkville usually runs $120-$260, and the reason it matters here more than in newer suburbs comes down to when the homes were built. Most Parkville houses went up between 1948 and 1970, and their dryer vents were never designed for modern high-efficiency dryers pushing air through 60-year-old galvanized pipe. When you call CleanRun at (806) 606-6902, you get a written price before anyone touches a panel, and you get photographs of every vent run before and after the work.
Why Parkville Homes Are Different
Parkville grew fast during Baltimore County’s postwar building boom, which means the ductwork in most homes is original sheet metal from the Eisenhower and Kennedy years. Those systems were built for oil-fired gravity furnaces, then adapted piecemeal when homeowners switched to forced-air gas or heat pumps. The result is a patchwork: undersized branch runs, dead-end sections that collect debris, and returns that were never sealed properly. We regularly find that the return-air chase in Parkville split-levels was just stud bays between interior walls, never a true duct at all. Decades of drywall dust, insulation particles, and rodent activity accumulate inside wall cavities that homeowners assume are clean enclosed passages.
The climate adds another layer. Parkville sits in the humid subtropical zone, where summer dew points in the mid-60s are ordinary. Warm, humid air meeting uninsulated galvanized ducts in unconditioned basements causes condensation inside the metal, and that moisture is what allows mold and bacteria to establish between cleanings. Add the mature oak and maple canopy over neighborhoods like Harford Park and Ridgeleigh, and you get heavy spring pollen loading that clogs return plenums faster than in less-wooded parts of the county.
Our Main Parkville Services
Most Parkville homeowners first call us for these two jobs, and each has its own dedicated page with full local pricing and detail.
Air Duct Cleaning in Parkville
Whole-system air duct cleaning for the kinds of homes that dominate Parkville: Cape Cods, ranchers, and split-levels with original trunk-and-branch ductwork running through unfinished basements. The job includes negative-pressure extraction on every run, cleaning of the supply and return plenums, and a documented photo record of the interior before and after. We see particular accumulation in the return chases of older Parkville homes, where builders used wall cavities instead of sealed duct. Full details are on the Air Duct Cleaning in Parkville page, including line-item pricing for this specific housing stock.
HVAC Cleaning in Parkville
HVAC cleaning goes beyond the ducts to the air handler, evaporator coil, blower assembly, and condensate pan. In Parkville’s humid summers, evaporator coils in 60-year-old systems grow biological film quickly, and that film reduces heat transfer and pushes musty air through the house. The HVAC Cleaning in Parkville page explains what gets cleaned, what it costs, and what our photo record shows you before and after.

BeforeAfterDryer Vent Cleaning in Parkville
Dryer vent cleaning in Parkville means clearing the full run from the dryer connection to the exterior termination, and in this housing stock the runs are often long, angled, and partially obstructed by rust scale from original galvanized pipe. A clogged dryer vent forces the dryer to work against back pressure, which drives up energy use and leaves lint accumulating around the drum and motor. We offer full-service Dryer Vent Cleaning with before-and-after photography on every run.
Dryer Vent Inspection
Signs you need it
Clothes take more than one cycle to dry, or the dryer exterior gets unusually hot during operation.
What it costs in Parkville
Inspection-only runs $90-$140, and that amount is credited toward cleaning if we find an obstruction.
How we do it
We camera-scan the full run from dryer collar to exterior vent cap, measure airflow at the termination, and document findings with photographs before any cleaning recommendation is made.
Vent Rerouting
Signs you need it
The vent path runs more than 25 feet or has multiple elbows, which is common in Parkville basements where dryers sit far from exterior walls.
What it costs in Parkville
Rerouting to a shorter, straighter path typically runs $260-$520 in Parkville homes depending on wall penetrations and termination hardware.
How we do it
We map the existing run, identify the shortest code-compliant exit, penetrate the wall or rim joist with a proper termination, and run rigid metal duct with mechanical connections.
What Dryer Vent Cleaning Costs in Parkville
| Item | Typical range in Parkville |
|---|---|
| Dryer vent inspection (credited toward cleaning) | $90-$140 |
| Full dryer vent cleaning | $120-$260 |
| Vent rerouting | $260-$520 |
How often should a dryer vent be cleaned in Parkville?
Every 12 to 18 months for most Parkville homes, and every 8 to 10 months if the run exceeds 15 feet or has more than two elbows, which older basements commonly do. The interval depends on dryer usage and vent length, not on a universal schedule.
Do you clean dryer vents on the roof in Parkville?
Yes, roof terminations are common on Parkville ranchers with first-floor laundry rooms. We carry ladder equipment for single-story and low-slope roofs, photograph the termination before and after, and confirm airflow at the cap before leaving. Call us for a written quote.
Duct Repair & Sealing in Parkville
Duct repair and sealing in Parkville usually means fixing what decades of basement work, previous HVAC replacements, and simple age have done to original sheet-metal ductwork: separated joints, rusted elbows, and return chases that leak conditioned air into wall cavities instead of delivering it to rooms. The return-air problem in Parkville’s Eisenhower-era split-levels is especially common, where builders used stud bays as return paths and never sealed them. We deliver full Duct Repair & Sealing with written scope and photo documentation, so you can see exactly what was leaking and what we sealed.
Duct Sealing
Signs you need it
Rooms at the far end of the house stay cold in winter or hot in summer even when the system runs constantly.
What it costs in Parkville
Sealing accessible duct joints and seams runs $350-$620 for a typical Parkville split-level or rancher.
How we do it
We locate leaks with a manometer or smoke test, clean the joint surfaces, apply mastic sealant or foil tape per manufacturer spec, and re-test static pressure before and after.
Flex Duct Repair
Signs you need it
Visible sagging, kinking, or tears in flexible duct runs in the basement or attic, often after pest activity or a previous remodel.
What it costs in Parkville
Replacing damaged flex duct sections typically runs $220-$520 in Parkville, depending on run length and accessibility.
How we do it
We remove the damaged section, install new insulated flex sized to the branch, reconnect with mechanical fasteners, and seal both ends with mastic.
What Duct Repair & Sealing Costs in Parkville
| Item | Typical range in Parkville |
|---|---|
| Duct sealing (accessible ducts) | $350-$620 |
| Flex duct replacement | $220-$520 |
| Return chase sealing | $300-$700 |
Can you seal the return chases in my Parkville split-level?
Yes, we seal stud-bay return chases by installing a metal or flex liner inside the cavity, closing the gaps at top and bottom plates, and sealing any penetrations. This converts an unsealed wall cavity into an actual return duct with documented air leakage reduction.
Why are my ducts sweating in my Parkville basement?
Uninsulated galvanized ducts carrying cool air through warm, humid basement air cause condensation on the exterior surface. We address this with duct insulation or by sealing leaks that pull humid air into the system. Get a written cost before work starts.
Air Quality & Sanitizing in Parkville
Air quality and sanitizing in Parkville homes usually starts with the same root cause: condensation inside aging ducts that weren’t insulated for the region’s humid summers, which feeds mold and bacteria and pushes musty air through every register. The mature tree canopy over neighborhoods like Ridgeleigh and Cromwell Valley means heavy spring pollen enters the return plenum and settles inside the duct liner. We deliver full Air Quality & Sanitizing with a documented photo record and a written treatment scope.
Mold Treatment
Signs you need it
Musty odor that gets stronger when the blower runs, or visible dark staining on registers or inside accessible duct sections.
What it costs in Parkville
Mold treatment for a typical Parkville duct system runs $450-$900, depending on the extent of visible colonization.
How we do it
We photograph affected areas, apply an EPA-registered antimicrobial labeled for HVAC use, then clean residue and re-photograph the treated surfaces for the record.
UV Light Installation
Signs you need it
Recurring biological growth on the evaporator coil or in the condensate pan, common in Parkville homes with older air handlers in humid basements.
What it costs in Parkville
UV light installation for a single air handler runs $400-$800 in Parkville including labor and equipment.
How we do it
We mount the lamp in the supply plenum or above the evaporator coil per manufacturer spec, wire it to the blower circuit, and confirm operation with the system running.
What Air Quality & Sanitizing Costs in Parkville
| Item | Typical range in Parkville |
|---|---|
| Mold treatment (duct system) | $450-$900 |
| Bacteria sanitizing | $250-$500 |
| UV light installation | $400-$800 |
Will sanitizing remove the musty smell from my Parkville ducts?
In most cases yes, if the odor originates from biological growth on duct surfaces or the coil. The treatment kills the source organism and the photo record shows the treated surfaces. If the smell returns, our 365-Day Done Right Promise applies. Call for a written quote.
Do you service the original ductwork in older Parkville homes?
Yes, we sanitize original galvanized duct systems from the postwar building era, including systems that were adapted from oil to gas. Older metal ducts are compatible with our sanitizing agents, and we document every treated run with before-and-after photographs.

What pushes a Parkville job toward the high end of these ranges is access. Basements with finished ceilings, return chases inside finished walls, and runs longer than 20 feet all take more labor to reach and document properly. You get a written price for your specific system before any work starts, and that price holds regardless of what the camera finds once we open the first panel.

FAQs About Air Duct Cleaning in Parkville
Most Parkville jobs are scheduled within three to five business days. We don’t promise same-day service because duct and vent work is scheduled deliberately: camera runs, written scope, cleaning, and photo documentation take time. When you call, we give you a specific appointment window, not a vague “we’ll be out this week.”
No, routine duct cleaning, dryer vent cleaning, and duct sealing do not require permits in Baltimore County. If a job involves structural changes like new wall penetrations for vent rerouting, we confirm the local requirements before work starts and handle that in the written scope, so there’s no surprise after the fact.
Yes, and that’s actually the most common situation we see in Parkville. Homes built between 1948 and 1970 with original ductwork often carry 60 to 70 years of accumulated dust, construction debris, and organic material. The camera shows us exactly what’s in there, and the photo record documents what came out.
If you want a written price for any of these services, call us at (806) 606-6902. We’ll schedule the job, photograph everything before and after, and put the number in writing before any work begins.
