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 Randallstown
Air duct cleaning in Randallstown runs $380-$680 for a typical split-level home’s full system, and most jobs are completed in 3-5 hours with before-and-after photo documentation included as part of the written scope. That’s the number we put on paper before a single register comes off. CleanRun Air Duct Cleaning works on the dense 1960s-80s housing stock along Liberty Road and Offutt Road every week. We know these split-levels, their unlined return chases, and the way summer humidity settles into 50-year-old sheet metal. Call us at (806) 606-6902 and we’ll give you a written price, not a vague estimate you have to trust.
Why CleanRun Air Duct Cleaning Is Randallstown’s Preferred Air Duct Cleaning Company
Randallstown homeowners don’t call us because we’re the cheapest. They call because they want to see what’s actually inside their ducts before and after the work. We’ve been doing that since 2013, across 52,000+ homes, and every job ends with a Documented Photo Record of each duct run. That means you see the 3-inch debris build-up at the first elbow in your return chase, and then you see it gone.
The split-levels near Milford Mill Road and Offutt Road are not like the newer subdivisions in Owings Mills or the row houses in Pikesville. The vertical return chases were often framed directly into interior wall cavities during original construction. That changes how the work gets quoted, how long it takes, and what a realistic outcome looks like. Tomas Reyes, who leads our crews, has walked enough of these homes to know that a “standard” cleaning doesn’t exist here. Haven Standard Clause 3 means verified, background-checked, uniformed technicians identified by name before they arrive. No anonymous subcontractors.
Our Air Duct Cleaning Services in Randallstown

Every Randallstown job starts with a written scope and price. No exceptions. That’s Haven Standard Clause 1, and it’s the reason homeowners who bought in the 2015-2025 window at high price points trust us with aging systems they didn’t install.
Residential Duct Cleaning
Full system cleaning for Randallstown’s split-levels, cape cods, and ranchers. We clean the supply side, the return side, the trunk lines, and the branch runs, plus the registers and grilles. The vertical return chases in these homes take extra time because we often have to work from the first-floor register upward with flexible agitation tools under negative pressure. That labor is included in the written price, not added as a surprise line item.

Commercial Duct Cleaning
Small offices, medical suites, and retail spaces along Liberty Road don’t need a national franchise quoting nonsense prices. We clean commercial duct systems with the same documentation standard: camera inspection before, a HEPA-filtered extraction during, and a photo record after. Business owners in Randallstown get a written price for the entire system, not a per-vent quote that multiplies once the crew walks in.

Supply Duct Cleaning
Supply ducts carry conditioned air from your furnace to the registers. In Randallstown’s older homes, these runs are often uninsulated sheet metal that sweats during Baltimore County’s humid summers. That condensation traps dust and creates the conditions for mold colonization. We clean the full length of every supply run, not just the first few feet from the register. If we find damage or a disconnected joint, we document it with the camera and give you the repair scope separately.

Return Duct Cleaning
This is where Randallstown’s split-levels diverge from almost every other housing type in the county. In many of these homes, the return “duct” is a drywalled stud bay with no metal liner at all. Cleaning it requires different tools and a different approach. We run agitation devices up the chase under continuous negative pressure with a HEPA-filtered vacuum, then send a camera inspection down the same cavity to confirm the bare framing is clean. If it isn’t, you’ll see it on the video. This is the section most competitors skip because they don’t know to look for it.

AfterTrusted Brands We Service in Randallstown
We work on systems that include Honeywell air cleaners, Aprilaire filtration, and Abatement Technologies HEPA equipment. That’s relevant for Randallstown homeowners because older homes in this area often have aftermarket filtration bolted onto furnaces that predate modern filter slots. If you have a Honeywell electronic air cleaner wired into a 1970s split-level furnace, the cleaning scope has to account for that. We don’t just clean around it. Our crew carries the right connectors and knows how to document the whole assembly before and after. You can verify every piece of equipment we bring by brand name before agreeing to any scope.
Common Air Duct Cleaning Problems We See in Randallstown Homes

- Drywalled stud bay returns. In split-levels near Milford Mill Road, the return side isn’t always a duct at all. It’s an unlined wall cavity that collects drywall dust, pet hair, and decades of recirculated air. Cleaning it requires tools that fit inside a stud bay, not a standard 8-inch duct brush.
- Water staining at the base of supply trunks. Baltimore County’s summer humidity regularly exceeds 70% RH, and uninsulated sheet metal in unconditioned crawlspaces sweats. That’s where we find rust, microbial growth, and debris caked onto the duct walls. We document it and clean what’s cleanable, and we tell you if sealing is the right next step.
- Multi-zone systems with disconnected branch runs. Split-levels were often built with single-stage furnaces and later retrofitted with zoning dampers. The ductwork wasn’t always designed for that. We find run sections that have pulled apart at the joints, pumping conditioned air into wall cavities instead of the rooms you’re trying to heat.
- Shared dryer vent stacks with no individual access. In some Randallstown townhome and condo clusters, multiple dryers share a stack that exits through the roof. You can’t clean one unit’s section without coordinating access. We’ll tell you exactly what’s accessible from your unit and what requires building-level coordination.

FAQs - Air Duct Cleaning in Randallstown

Because the return side runs vertically through interior wall chases instead of open attic or basement spaces, and that requires flexible access equipment, slower agitation, and a camera verification pass that a single-story rancher doesn’t need. In a rancher, the return trunk is usually accessible from the basement or crawlspace in a straight run. In a Randallstown split-level, the return chase often starts at a first-floor register and goes vertically through a stud bay, and accessing it from the upper floor isn’t possible without opening drywall. We work from the lower register upward, which is slower but doesn’t damage the wall. The labor difference is real, and it’s reflected in the written price you get before work starts. Call (806) 606-6902 and we’ll quote your specific floor plan, not a generic square footage number.
Yes, we clean unlined chases without cutting drywall by running agitation tools from the first-floor register up the cavity under negative pressure, then confirming the result with a camera. The critical thing to understand is that cleaning is not the same as sealing. An unlined stud bay is porous and will re-contaminate faster than a lined duct, and no sanitizing fog will adhere to bare drywall and framing. We’ll give you a written scope that separates what cleaning accomplishes from what sealing would accomplish, and we won’t sell you a sealing job as part of the cleaning price. That’s the kind of clarity a generic duct company won’t offer.
Shared stacks mean your dryer vent isn’t yours alone, and cleaning just your section may not resolve a blockage that’s downstream of your unit. We’ll inspect your accessible run with a camera, document what’s in your section, and tell you precisely whether the obstruction is yours or in the shared portion. If it’s in the shared stack, you’ll need building management involved. We’ll give you the written inspection record to take to them. We don’t pretend to clean what we can’t reach.
Source removal means the debris is physically extracted from the duct system under negative pressure using HEPA-filtered vacuum equipment, not just loosened and pushed around. That’s the method defined by NADCA, the industry association for HVAC cleaning, and it’s the only approach that works on aging sheet metal with decades of caked-on dust, pollen, and rust scale. A brush-only cleaning without adequate negative pressure just redistributes the debris into your living space and back through the furnace. In Randallstown’s humid climate, that leftover organic material is exactly what feeds mold growth in the next summer.
Yes, and more urgently than homes with short direct vents to the exterior. Long horizontal runs in Randallstown’s split-levels and cape cods accumulate lint faster because the air velocity drops as the run extends, so lint settles in the middle of the run instead of exiting the termination. Combined with the humidity in a basement laundry room, that lint can cake into a hard obstruction that contributes to dryer overheating. We’ll clean the full run, document the before and after with the camera, and tell you if the run itself is too long for your dryer’s rated capacity. Call (806) 606-6902 for a written inspection and cleaning quote.
You’ve seen the specifics. If your Randallstown home was built between 1960 and 1985, the odds are high that no one has ever cleaned the vertical return chases, and the written documentation you’ll get from CleanRun will tell you exactly what’s in there. Call (806) 606-6902 for a written estimate, or if you already have a competitor’s number, bring it in and we’ll put our price next to it in writing. No visit required for the comparison.
