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 Pikesville
Air duct cleaning in Pikesville, MD typically runs $350 – $650 for a whole-home system, and most jobs are scheduled within a week. Hollis Air Duct Cleaning has been serving Pikesville since 2004, and our crews know the split-levels, ranches, and colonials built during the 1950s – 1970s boom that define this area’s housing stock. We dispatch from our Baltimore office, so Pikesville homeowners aren’t waiting on crews driving up from D.C. or down from Pennsylvania. Call (361) 326-5060 for a free estimate with a written price before any work starts.
Our technicians carry Rotobrush rotary systems and Nikro negative-air machines, the same equipment used in commercial buildings. We background-check and uniform every tech, and we follow The Garrison Code on every Pikesville job: arrive inside the window, price in writing, complete the work by the book, leave the site clean. The 365-Day Done Right Promise covers every repair. If it fails within a year, we return and make it right at no charge, including a free second visit.
Why Hollis Air Duct Cleaning Is Pikesville’s Preferred Air Duct Cleaning Company
We’ve built our reputation in Pikesville on showing up and doing what we said we’d do. That sounds basic, but in this trade it’s rarer than it should be. Our Pikesville customers aren’t looking for the lowest coupon price; they’re looking for the bid they can trust. We give that in writing before any equipment touches their ducts.
Our response time to Pikesville is typically same-week scheduling, with dispatch coordinated from our Baltimore office. That matters when you’re prepping for Passover or Rosh Hashanah and need clean ducts before family arrives. We know the local rhythm: spring pollen season, fall leaf drop, and the pre-holiday rush that hits Pikesville harder than most Baltimore suburbs because of the area’s large Jewish population.
Our crews know the difference between a 1962 split-level off Old Court Road and a 1975 colonial near Reisterstown Road. They’ve found crushed flex runs in attics, disconnected returns in crawlspaces, and gravity-fed systems near the Baltimore County line that require careful handling. That local knowledge prevents the damage that happens when a crew treats every house like it’s new construction.
Commercial Air Duct Cleaning in Pikesville
Commercial Air Duct Cleaning in Pikesville covers office buildings, medical suites, retail spaces, and multi-unit properties where code compliance and occupant health are both on the line. The work involves source-removal cleaning of supply and return ductwork, coil and air handler cleaning, and HEPA-filtered negative-air containment to prevent debris migration into occupied spaces. A typical commercial system in Pikesville runs $800 – $2,500 depending on square footage, access difficulty, and whether the building dates to the postwar era with original ductwork. We schedule commercial jobs to minimize disruption to your operations, and we provide written certification of completion for property management records.
Medical and Professional Office Cleaning
Medical suites and professional offices in Pikesville require documented cleaning protocols and containment procedures. We use Abatement Technologies HEPA filtration and sealed negative-air machines to meet the standards that liability insurers and county health inspectors expect. Every job gets a written report with before-and-after photo documentation.
Retail and Restaurant Systems
Grease-laden vent hoods and high-traffic retail spaces in Pikesville need more than a surface vacuum. We pull registers, clean trunk lines, and inspect for fire-code compliance in kitchen exhaust systems. The work is priced by the system, not by the vent, so your invoice matches the written quote.
Air Duct Cleaning Services in Pikesville
Air Duct Cleaning Services in Pikesville address the specific problems of an aging housing stock: decades of pollen accumulation, original galvanized ductwork with rough interior surfaces that trap debris, and the crushed or disconnected flex runs that turn a “cleaning” into a partial job if the crew doesn’t inspect first. A typical residential whole-system cleaning in Pikesville costs $350 – $650, with older homes at the higher end due to access difficulty and the agitation tools needed to break loose the sticky pollen film. We include video inspection on most Pikesville jobs because we’ve learned that what you can’t see in a 1960s split-level usually matters more than what you can.
Video Inspection and System Mapping
We run camera inspection before and after cleaning on most Pikesville homes. The footage shows you exactly what’s inside your ducts: the pollen film, the disconnected run, the mold bloom in the attic flex. It’s not a sales tool; it’s how we know the job is complete and how you know what you paid for.

Duct Sealing and Repair
Cleaning without sealing is often half a job in Pikesville’s older homes. We find disconnected returns and crushed supply lines on roughly one in three split-levels built between 1960 and 1975. Our crews carry mastic sealant and mechanical fasteners to reconnect and seal what we find, with the repair cost written into the original quote or presented separately before any work proceeds.

Trusted Brands We Service in Pikesville
Our Pikesville crews work with equipment and filtration from Rotobrush, Nikro, Aprilaire, and Abatement Technologies. The Rotobrush rotary brush system scrubs the interior of round ductwork where contact vacuuming fails. Nikro negative-air machines maintain HEPA-filtered suction on the entire system during cleaning, preventing debris from blowing back into your living space. For filtration upgrades, we stock Aprilaire media cabinets and replacement filters sized to Pikesville’s common system configurations. We don’t sell what we wouldn’t install in our own homes, and we explain what each component does before you decide.
Common Air Duct Cleaning Problems We See in Pikesville Homes
- Crushed flex runs in 1960s split-level attics. The original flex duct in Pikesville’s split-levels degrades under decades of attic heat and humidity. Our camera inspection finds collapsed or disconnected runs that bypass half the system, explaining why some rooms never get adequate airflow even after a “cleaning.”
- Sticky pollen-leaf film from the oak canopy. The mature oaks and maples along Old Court Road and Reisterstown Road produce fine pollen that combines with leaf litter to form a tacky coating on duct interiors. Standard vacuuming won’t remove it; we use mechanical agitation tools to break it loose before extraction.
- Undersized gravity-fed returns near the Baltimore County line. Older homes in this pocket have return systems that predate modern HVAC design. Without proper negative-air containment, cleaning dislodges debris directly into the air handler, contaminating what you just paid to clean.
- Mold bloom in humid attic crawlspaces. Pikesville’s humid summers create condensation in poorly ventilated attic duct runs. We find visible mold on roughly one in four camera inspections of 1960s – 1970s homes, and we address it with source removal and sealing, not chemical fogging that masks the problem.
Pricing for Air Duct Cleaning in Pikesville, MD
Whole-home residential air duct cleaning in Pikesville typically costs $350 – $650. Commercial systems run $800 – $2,500. The variables are straightforward: system size, access difficulty, condition of original ductwork, and whether we find disconnected or damaged runs that need repair.
We do not quote per-vent pricing. That structure invites bait-and-switch tactics: a low teaser rate multiplied across 15 or 20 vents, plus “unexpected” charges once the crew is inside. Our price is one flat rate per system, agreed in writing before work begins. If camera inspection reveals additional needed repairs, we show you the footage and present a separate written price. You approve it or we proceed with cleaning only. No invoice surprises at the door.
Free estimates are available by calling (361) 326-5060. We’ll ask about your home’s age, system type, and any specific problems you’ve noticed, then give you a realistic range before scheduling.

FAQs About Air Duct Cleaning in Pikesville
The musty smell usually comes from a disconnected or crushed flex run in the attic or crawlspace, plus mold bloom on the interior surface of the duct. Standard vacuuming at the registers never reaches these hidden sections. Our camera inspection locates the failure, then we use negative-air HEPA containment and agitation tools to remove the contamination and seal the reconnected run. Call (361) 326-5060 if you’re dealing with recurring musty odors – we’ll inspect before quoting.
Spring brings heavy pollen from oak, maple, and sycamore trees that infiltrates outdoor HVAC intakes and coats duct interiors. Fall follows with leaf litter and the start of closed-window heating season, stirring up accumulated dust. Many Pikesville families also schedule pre-holiday cleaning before Passover and Rosh Hashanah gatherings. We recommend booking 2 – 3 weeks ahead during these peaks. Call (361) 326-5060 to reserve your preferred date.
Yes, with the right equipment and technique. Galvanized steel ductwork from the 1950s – 1970s has rough interior seams that trap debris but also requires lower-pressure agitation to avoid dislodging the zinc coating or loosening joints. We use Rotobrush rotary systems with adjustable torque and avoid high-pressure air whips that can damage older metal. Camera inspection before and after confirms integrity. Call (361) 326-5060 for a free assessment of your specific system.
Commercial cleaning in Pikesville follows a contained, documented protocol: HEPA-filtered negative-air machines isolate the work zone, rotary brushes and contact vacuums remove debris from trunk lines and branches, and we clean coils and air handlers. We schedule around your hours, provide written completion certificates, and photograph before-and-after conditions. Typical commercial pricing is $800 – $2,500 depending on system size and access. Call (361) 326-5060 for a site-specific quote.
A MERV upgrade helps maintain clean ducts but only if your system can handle the airflow restriction. Many Pikesville’s older homes have blower motors and duct sizing designed for basic fiberglass filters. We test static pressure and recommend Aprilaire or Honeywell media filters sized to your actual system capacity, not the highest MERV number available. The upgrade is optional and priced separately. Call (361) 326-5060 to discuss filtration after your cleaning.
