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 Company in Parole, MD
Air duct cleaning in Parole typically costs $350 – $650 for a whole-home system, with most jobs scheduled within a few days and completed in a single visit. Hollis Air Duct Cleaning, part of the Garrison Partners family and led by Roy Castellanos, specializes in the aging flex-duct and sheet metal systems common to Parole’s 1970s – 1990s housing stock. We use Rotobrush rotary brush systems and Nikro negative-air machines to remove mold, pollen, and debris that Maryland’s humid climate pushes deep into ductwork. Call (361) 326-5060 for a written estimate before any work begins.
Why Parole Homes Are Different
Parole sits at the dense heart of Anne Arundel County’s suburban corridor, and that density shapes every job we run here. The area’s housing is overwhelmingly mid-to-late 20th century: split-levels, townhouses, and low-rise condos built between the 1970s and 1990s with original ductwork that was often flex duct or unsealed sheet metal. These systems are now 20 – 40 years old, and many were never designed for the near-constant operation that Maryland heat pumps demand.
The humid subtropical climate here is the other factor. Hot, muggy summers and cool, damp winters create condensation cycles inside ductwork that promote mold and dust mite colonies. Spring pollen surges from the Annapolis-area forests clog return vents faster than in less wooded suburbs. Many Parole condos and townhomes also have shared duct chases or tightly routed runs that require coordination with HOAs for access, and equipment compact enough to navigate utility closets and crawl spaces. We carry the tools for that constraint, and we know the local HOA notification norms.
Our Main Parole Services
Most Parole homeowners call us for one of three jobs. Each has its own page with full pricing, process details, and Parole-specific conditions.
Air Duct Cleaning in Parole
We clean the full supply and return network with a Rotobrush rotary brush system that scrubs debris off duct walls, paired with a Nikro negative-air machine that pulls it out under controlled suction. In Parole, we often find mold staining in flex duct that has sagged or pooled condensation, especially in homes near the wooded edges where humidity lingers. We photograph the before condition and the after. Air Duct Cleaning in Parole covers full pricing and what to expect on the day.
Dryer Vent Cleaning in Parole
Dryer vent blockages are a fire risk, and Parole’s townhome clusters see them frequently because long, shared vent runs exceed the 25-foot recommendation in many units. We clear the full run from appliance to termination, check airflow with a meter, and flag any code issues. If your dryer takes two cycles to finish a load, the vent is likely the problem. Dryer Vent Cleaning in Parole has the details.
Duct Sealing in Parole
Leaky ducts waste 20 – 30% of conditioned air in typical Parole homes, and the original mastic or tape has often dried out. We seal accessible joints with duct sealing mastic and mechanical fasteners, then pressure-test the system to verify the improvement. This is especially effective in homes with rooms that never seem to match the thermostat. Duct Sealing in Parole explains the process and pricing.
