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.

AfterFast, Reliable Air Duct Cleaning Across Overlea
Air duct cleaning in Overlea typically runs $450 – $850 for a full residential system, and most jobs are completed in a single visit with the price written down before we start. We dispatch crews from our Baltimore office to serve Overlea directly, so you’re not waiting on a van routed from the outer suburbs. Our technicians know the older Beltway corridor homes here, from the capes along Belair Road to the bungalows tucked behind Fullerton Avenue, and they arrive equipped for the short trunk-and-branch runs and basement-accessible ductwork that define this market.
Call (361) 326-5060 for a free estimate. We’ll ask about your home’s age, your system’s layout, and what you’ve noticed, then schedule a visit with a written price that doesn’t move at the door.
Why Hollis Air Duct Cleaning Is Overlea’s Preferred Air Duct Cleaning Company
We’ve been sending crews to Overlea since 2004 as part of the Garrison Partners family, and our reputation here is built on showing up inside the window and leaving the site clean. Overlea homeowners aren’t looking for the cheapest coupon in the mail; they’re looking for a crew that won’t track mud through a 1950s cape, won’t invent a new price once the basement stairs are descended, and will still answer the phone if something isn’t right six months later.
Our 365-Day Done Right Promise covers every job in writing. If the work fails within a year, we return and make it right at no charge, including a free second visit. That matters in Overlea, where many homes have seen multiple HVAC contractors over the decades and homeowners are tired of being passed between companies that won’t stand behind their work.
Every technician is background-checked and uniformed. You know who’s arriving before they knock. Phones are answered by a live person 24 hours a day, seven days a week. No voicemail loops, no callback queues, no waiting until Monday to schedule.
We coordinate dispatch from our Baltimore office, which means Overlea is local to our routing, not an afterthought. Crews carry Rotobrush rotary brush systems and Nikro negative-air machines, the same tools used in commercial buildings, sized appropriately for the modest square footage and tight joist bays common in Overlea’s housing stock.
Air Duct Inspection in Overlea
Air Duct Inspection in Overlea is often the most important service we perform, because the real problems in these older homes are rarely visible from the registers. Our inspection runs $150 – $275 and includes a full camera pass of accessible trunk lines, return plenums, and basement ceiling cavities, plus a written report with photos. We recommend an inspection before any cleaning when a home was built before 1970, when rooms heat or cool unevenly, or when a new blower was installed on old ductwork.
What the Camera Reveals in Older Basements
In Overlea’s Fullerton and Kenwood neighborhoods, we regularly find flex runs that have pulled loose from trunk collars, crushed by decades of storage boxes pushed against basement ceilings, or never properly connected during a prior HVAC replacement. The camera shows it. We photograph it. You see it before we quote any repair.
Sizing Verification for Modern Blowers
Many Overlea returns were sized for gravity furnaces or early forced-air systems moving half the air volume of modern equipment. Our inspection measures static pressure and visualizes duct dimensions to flag when the duct is too small for the blower, which causes short-cycling, uneven rooms, and premature motor failure. Cleaning alone won’t fix that. We’ll tell you straight.
Residential Air Duct Cleaning in Overlea
Residential Air Duct Cleaning in Overlea is a different job than in new construction subdivisions. Our full-system cleaning runs $450 – $850 for a typical 1,200 – 2,200 square foot home, with larger or more complex systems up to $1,200. The work includes agitation of supply and return ducts under negative-air pressure with HEPA filtration, register and boot cleaning, and a final camera verification. We clean what we can access; if we find disconnected or damaged ductwork, we stop, show you, and quote repair separately with a written price.
Rotary Brush and Negative-Air Method
We use Rotobrush rotary brush systems for the mechanical agitation that breaks loose adhered debris in sheet metal and flexible duct, paired with Nikro negative-air machines that maintain constant suction so dislodged material is captured at the source, not blown through your home. In Overlea’s tight joist bays, this controlled extraction matters more than in open basement trunks.
Sealing What Cleaning Exposes
Cleaning often reveals gaps at trunk connections, failed tape, or seams that were never sealed with mastic. We carry Guardsman duct sealing products and can apply sealant to accessible leaks the same day, with a separate written price before we start. The combination of cleaning and sealing is what actually fixes uneven airflow in these older homes.
Trusted Brands We Service in Overlea
Our crews arrive with professional-grade equipment from Rotobrush, Nikro, and Abatement Technologies, plus filtration and sealing products from Honeywell, Aprilaire, and Guardsman. These aren’t hardware-store tools; they’re the same systems used in hospitals and commercial buildings, maintained to manufacturer spec and sized for residential ductwork. For Overlea homeowners, this means we can complete most jobs without ordering parts or making return trips. If your system needs a specific filter size or sealing compound, we stock common configurations and can source others quickly through our Baltimore supply chain.
Common Air Duct Cleaning Problems We See in Overlea Homes
- Crushed flex runs in basement ceiling cavities. In the older capes near Kenwood, we regularly find flexible duct that was compressed when a prior homeowner finished a basement ceiling or stored items against the joists, cutting airflow to first-floor rooms without anyone realizing.
- Undersized returns choking modern blowers. The original gravity-system returns in many Overlea bungalows were never enlarged when forced-air blowers were installed, so the motor works harder, cycles shorter, and dies sooner. Cleaning the duct doesn’t change the physics of too-small pipe.
- Lint migration from shared dryer vent pathways. In homes where dryer vents and duct runs share joist bays, lint bypasses the trap and accumulates in the ductwork beyond, creating both airflow restriction and fire risk. We flag this during inspection and can clean dryer vent lines as a separate service.
- Decades of construction debris in short trunk-and-branch runs. Overlea homes that have seen repeated HVAC replacements often have layers of old tape, fallen insulation, and sawdust from prior work lodged in corners that newer, straighter ductwork doesn’t have.
Pricing for Air Duct Cleaning in Overlea, MD
Most full residential cleanings in Overlea fall between $450 and $850. A basic system with accessible basement trunk, standard register count, and no complicating factors starts near the lower end. Homes with multiple zones, finished basements that limit access, or significant contamination requiring extended agitation time run higher. Commercial systems and larger residential properties range $900 – $1,500.
What moves the price: accessibility of ductwork, number of supply and return branches, presence of flexible duct versus all sheet metal, and whether we find damage requiring repair or sealing. We do not price per vent. We price per system, agreed in writing before work starts, and that number does not change when the technician arrives.
Air duct inspection is $150 – $275 and is credited toward cleaning if you proceed same-day. Dryer vent cleaning, often bundled with duct cleaning in Overlea’s older homes, runs $150 – $250 as an add-on. Call (361) 326-5060 for an exact quote. Estimates are free.

FAQs About Air Duct Cleaning in Overlea
Because the real problem is frequently structural, not just dirty. Overlea’s mid-century capes and bungalows often have return ducts sized for original gravity or early forced-air systems, now undersized for modern blowers, plus crushed or disconnected flex runs hidden in basement ceilings. We find this on inspection, explain it with photos, and quote repair separately with a written price. Call (361) 326-5060 to schedule an inspection.
A camera pass of all accessible trunk lines, return plenums, and branch connections, with photos of what we find. In Overlea’s tight joist bays, we pay particular attention to flex runs in finished ceiling cavities and to measuring whether returns can handle current blower volume. The inspection takes 45 – 90 minutes and costs $150 – $275, credited toward cleaning if you proceed. Call (361) 326-5060 to book.
Overlea’s mature oak and maple canopy produces heavy pollen loads in spring, and I-695 traffic contributes fine particulate that infiltrates older homes with less tight envelopes. Combined with humid summers that drive condensation in ductwork, this means returns accumulate debris faster than in newer, better-sealed construction. Cleaning intervals of 3 – 5 years are typical here, versus 5 – 7 in drier, less wooded areas.
Yes. Our negative-air method with HEPA filtration, contained agitation, and post-cleaning verification aligns with NADCA ACR guidelines for residential duct cleaning. We document the work with before-and-after photos of your specific ducts, not stock images. The 365-Day Done Right Promise backs every job in writing. Call (361) 326-5060 for specifics on our process.
In older Overlea homes where dryer vents share joist bays with HVAC ductwork, lint can migrate past the trap and accumulate in duct runs, creating both airflow restriction and fire hazard. We inspect for this condition during our camera pass and offer dryer vent cleaning as a separate, written-price service. If we see lint migration, we’ll show you and explain your options. Call (361) 326-5060 to schedule.
