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 Riva, MD
Full-system air duct cleaning in Riva, MD typically runs $450 – $850 for a standard home, with most jobs completed in a single visit. What drives the actual price is the local microclimate: Riva’s tidal marsh setting and dense hardwood canopy create a combination of heavy pollen loads and persistent humidity that most inland Maryland markets simply don’t face. We’re Hollis Air Duct Cleaning, part of the Garrison Partners family, and our crews serving Riva understand that ductwork here often needs antimicrobial treatment and condensate inspection, not just a surface vacuum. Call us at (361) 326-5060 for a written quote before any work begins.
Why Riva Homes Are Different
Riva sits where the South River meets tidal marsh and mature forest, and that geography reshapes every duct cleaning job we do. The housing stock is predominantly 1970s – 1990s two-story colonials and split-levels on wooded lots off Riva Road and surrounding streets. Many still run original braided flex duct and unsealed trunk lines, with air handlers drawing return air from raw crawlspace or basement air.
The real issue is what that air carries. Spring oak and sweetgum pollen from the surrounding woods coats return grilles and blower wheels by late April. By June, the same humid conditions produce black mildew speckling on north-facing flex runs in crawlspaces. Two failure modes, weeks apart, both tied to Riva’s position on the Chesapeake’s western shore. Hot, muggy summers keep HVAC systems under near-continuous load from May through September, so condensation and microbial growth dominate here, not dry-air dust. When we open a system in Riva, we’re often looking at antimicrobial fogging and condensate-line inspection as standard procedure.
Our Main Riva Services
Most Riva homeowners call us for one of three jobs. Each has its own page with full pricing and process details.
Air Duct Cleaning in Riva
We clean the full supply and return network with a Rotobrush rotary brush system and negative-air extraction, then inspect for the pollen buildup and mildew spotting that Riva’s woods and humidity produce. Every job gets a written price upfront and our 365-Day Done Right Promise. Air Duct Cleaning in Riva covers full pricing and what to expect.
Dryer Vent Cleaning in Riva
Dryer vents in Riva’s older colonials often run long horizontal routes through crawlspaces or exterior walls, where humid foundation air slows exhaust and accelerates lint packing. We clear the full run with rotary tools and airflow verification, not just a shop vac at the termination. Dryer Vent Cleaning in Riva has full details.
Duct Sealing in Riva
Unsealed trunk lines and degraded flex duct connections are common in Riva’s 1970s – 1990s housing stock. We seal leaks with mastic and mechanical fasteners, then pressure-test to confirm the fix. Sealed ducts cut the load on your air handler and reduce the humid, unconditioned air pulled from crawlspaces. Duct Sealing in Riva explains the full process.
