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 HVAC Cleaning Across Randallstown
HVAC cleaning in Randallstown usually means one of two things: cleaning the ductwork that moves air through your home, or cleaning the mechanical components inside your furnace and air handler. Most Randallstown homes need both, but they’re different jobs with different prices. We’re CleanRun Air Duct Cleaning, and we’ve worked in split-levels, ranchers, and cape cods along Liberty Road, Offutt Road, and Milford Mill Road long enough to know exactly what’s inside those walls. If you want a written price before any work starts, call (806) 606-6902. That’s how every job begins, no exceptions.
Why CleanRun Air Duct Cleaning Is Randallstown’s Preferred HVAC Cleaning Company
Randallstown’s housing stock is specific. Most homes were built between the late 1950s and early 1980s, and the predominant floor plans are split-levels and ranchers with sheet-metal ductwork that’s now 40 to 60 years old. That matters because a cleaning crew that treats every house like a newer Owings Mills colonial will miss what’s actually wrong. We don’t. When our technicians arrive at a Randallstown job, they expect vertical return chases, tight mechanical closets, and ducts that have never been professionally touched. That expectation is built into our process, our pricing, and our equipment choices.
Every CleanRun job in Randallstown starts with a written price delivered before a single panel comes off. That’s HVAC Cleaning done the way it should be: documented, specific, and accountable. We photograph the inside of every duct run before and after, then deliver that photo record to you as part of the standard job file. That’s not an add-on. It’s how we’ve operated since 2013, and it’s why Randallstown homeowners who research every service category before calling tend to end up with us.
Tomas Reyes leads our crews with one rule: if you can’t show the customer what you found, you haven’t earned the price. That approach matters in Randallstown, where unlined stud-bay returns hide behind drywall and where a “cleaning” that skips the evaporator coil leaves the system re-dirtying itself within a season. We document, we explain, and we stand behind the work with the 365-Day Done Right Promise, in writing, on every job.
Our HVAC Cleaning Services in Randallstown

Evaporator Coil Cleaning
In Randallstown’s humid summers, the evaporator coil inside your air handler becomes a condensation point. When that coil is coated in dust and pet hair, it can’t shed water efficiently, and you end up with reduced cooling and higher humidity inside the home. Our evaporator coil cleaning removes that buildup using professional-grade coil cleaners and agitation tools, then we photograph the coil before and after so you see the difference. For split-levels near Milford Mill Road, where mechanical closets are tight, our techs use flexible camera inspection to access coils that would otherwise go untouched.

Air Handler Cleaning
Randallstown’s split-level homes often have air handlers tucked into basement corners or crawlspace-adjacent closets with limited clearance. We clean the blower housing, fan blades, and interior cabinet surfaces, then run the system to confirm airflow is restored. A dirty blower wheel can reduce airflow by 20% or more, which forces your system to run longer and costs you money every month. This is one of the most skipped steps in cheaper “duct cleaning” packages, and it’s one we never skip.

Blower Cleaning
The blower motor and fan wheel move every cubic foot of air your home circulates. In Randallstown homes with original 1970s-era furnaces, those blower wheels often carry decades of accumulated dust that throws the wheel out of balance. We remove, clean, and reinstall blower assemblies using HEPA-filtered negative pressure to capture what we dislodge. If your Randallstown home has a furnace closet off a finished basement, we bring the right access equipment to work in that space without damaging finished walls or flooring.

Condenser Cleaning
Your outdoor condenser sits in Randallstown’s pollen-heavy air every spring, and the cottonwood and oak pollen along the Patapsco watershed corridors can mat the coil fins badly. We clean condenser coils with low-pressure water and coil-safe cleaners, then check the refrigerant lines and electrical connections visually. A clogged condenser coil makes your whole system work harder, which shortens its life and raises your cooling bill. For homes along Liberty Road where landscaping sits close to the condenser, we’ll also clear vegetation that restricts airflow.

Common HVAC Cleaning Problems We See in Randallstown Homes

- Unlined stud-bay return chases. In split-level neighborhoods near Milford Mill Road, vertical return-air chases were often framed directly into interior wall cavities during original construction. That means the “duct” is sometimes a bare drywalled stud bay with dust caked on raw framing, and cleaning it properly requires camera inspection, flexible agitation tools, and careful negative-pressure work so debris doesn’t blow into wall cavities.
- Dirty evaporator coils and blower motors. We regularly see systems where the ducts were cleaned at some point but the coil and blower were never touched. In Randallstown’s humid climate, that means the coil re-wets every summer and the dust left behind turns into a sticky paste that strangles airflow.
- Pollen-clogged return grilles. The heavy deciduous tree canopy along stream corridors draining toward the Patapsco watershed pushes significant seasonal pollen loads through Randallstown neighborhoods. Return grilles clog fast every spring, and that restriction causes the blower to pull air from wherever it can, including wall cavities and crawlspaces.
- Multi-zone duct runs with poor access. Split-level floor plans create vertical return chases and multi-zone supply runs that are far more labor-intensive to clean than a single-story ranch or a newer colonial. A crew that prices a Randallstown split-level the same as an Owings Mills two-story is either cutting corners or doesn’t understand what they’re walking into.
Pricing for HVAC Cleaning in Randallstown, MD
In Randallstown, a full HVAC cleaning that includes air handler cleaning, blower cleaning, and evaporator coil cleaning typically runs between $450 and $850 depending on system size and the number of zones. Evaporator coil cleaning alone typically runs $180 to $340. If your home has an unlined stud-bay return that requires camera mapping and careful sealing, expect that to add $150 to $300 to the scope because of the additional labor and access work involved. A full duct cleaning with photo documentation on a typical Randallstown split-level with eight to twelve supply runs generally runs $600 to $1,100. We deliver a written price before any work starts, under Haven Standard Clause 1, and that price is the price, not a teaser. If you have a written estimate from another company, bring it in and we’ll put our number next to it in writing as a Free Second Opinion. Call (806) 606-6902 for a fixed, written quote specific to your home.

FAQs - HVAC Cleaning in Randallstown

Because in many Randallstown split-levels, the vertical return chase is not a round metal duct. It’s a drywalled stud bay framed into an interior wall cavity, which means there’s no smooth interior surface to guide cleaning tools. Our techs use flexible camera inspection to map the cavity first, then work with agitation tools and negative pressure to pull debris out without blowing it into adjacent wall cavities. That process takes more time than a straight metal duct run, which is why we scope it separately and show you the camera footage before we start. Call (806) 606-6902 and we’ll explain exactly what your home’s return configuration means for the job.
Yes, in most Randallstown apartment and condo buildings we can clean the individual unit’s air handler, blower, and the duct runs that serve that unit, even when the building shares a central system. The scope depends on where the unit’s access points are and whether the building’s mechanical room is accessible to our crew. We coordinate with property management on parking and access, and we document every run we clean with before-and-after photos. If you’re in a shared building near Liberty Road, we’ll confirm access details before we quote so the written price reflects reality, not assumptions.
We coordinate parking and access before the job starts. On narrow streets and tight shared driveways in Randallstown’s townhome communities, our crews stage equipment efficiently and keep the footprint to a single vehicle where possible. We confirm with you, and with property management if applicable, where the truck can sit without blocking neighbors. If parking doesn’t work, we’ll tell you before we schedule, not after we arrive. That’s part of why we insist on a phone conversation before any Randallstown job is booked.
Yes, sustained summer humidity above 70% creates condensation inside older, poorly insulated supply runs, and that moisture supports mold and mildew growth wherever dust has accumulated. The risk is highest in Randallstown homes with original 1960s and 1970s ductwork that was never sealed or insulated to modern standards. If our camera inspection shows microbial growth, we’ll show you the footage and recommend a sanitizing scope as part of the written plan. You decide what gets done, but you’ll have the evidence in front of you first.
Because Randallstown sits under a heavy deciduous canopy, particularly along the stream corridors that drain toward the Patapsco watershed, and that canopy releases enormous pollen loads every spring. The pollen clogs return grilles quickly, and if your return filter is undersized or the grille is already the bottleneck in your system, it doesn’t take long for airflow to drop. We’ll check your return sizing and filter setup as part of any full cleaning, and we’ll show you what’s actually collecting in the return chase with camera footage. Want to know what’s in your returns right now? Call (806) 606-6902 and we’ll schedule a written-price inspection.
