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 Deale
Air duct cleaning in Deale, MD typically costs $350 – $650 for a full residential system and is usually scheduled within a few days, with most jobs completed in 3 – 5 hours. Our crews serve Deale from our Washington, DC dispatch office, and we’ve learned that homes here need something different than standard inland cleaning.
We’re Hollis Air Duct Cleaning, and we’ve spent enough time in Deale to know the difference between a cottage on Franklin Gibson Road and a townhome off Deale Beach Road. The salt air coming off the Chesapeake Bay, the humidity that hangs in the ducts of seasonal rentals all winter, the original galvanized ductwork in waterfront homes built in the 1960s and 70s. These aren’t abstract problems for us. We’ve pulled mold-covered flex duct from a rental on Rockhold Creek that sat empty from October to May. We’ve replaced corroded trunk lines in a cottage where the salt air had eaten through the seams. When you call (361) 326-5060, you’re talking to a live person who knows Deale is south of Route 256, not somewhere near Annapolis, and who can get a crew to your door with the right equipment for what this specific place does to ductwork.
Why Hollis Air Duct Cleaning Is Deale’s Preferred Air Duct Cleaning Company
Deale homeowners don’t hire us because we’re the cheapest. They hire us because the last crew gave a phone estimate of $199 and handed them a $900 invoice. Our Air Duct Cleaning team writes the price down before touching anything, and that number doesn’t move.
We’ve built our reputation in Deale on showing up inside the window we promised, in uniform, with background-checked technicians who follow The Garrison Code on every job. That means arriving squared away, pricing in writing, completing the work by the book, and leaving the site clean. No exceptions.
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. Most competitors in the trade won’t put that in writing. We do, on every Deale job.
Phones are answered by a live person 24 hours a day, 7 days a week. No voicemail loops, no callback queues, no waiting until Monday morning to schedule something you noticed on Saturday.
Vent Cleaning in Deale
Vent cleaning in Deale means more than brushing out dust bunnies. Because of the humidity and salt air, we regularly find vents with visible mold staining, corrosion around the register screws, and a layer of sticky particulate that standard vacuuming won’t touch. A typical residential vent cleaning in Deale runs $150 – $300 for supply vents only, or $250 – $450 when combined with return vent cleaning.
Supply Vent Cleaning
Supply vents push conditioned air into your rooms. In Deale’s older waterfront cottages, we often find these vents partially blocked by deteriorating duct liner or corrosion flakes from salt air exposure. Our rotary brush system breaks that material loose, then we extract it with negative-air equipment so nothing settles in your living space.
Return Vent Cleaning
Return vents pull air back to your HVAC system, and in Deale they work harder than inland homes because the system runs longer during humid summers. These vents collect the most debris, and if they’re pulling through a filter that’s been neglected, the buildup can restrict airflow by 20% or more. We clean the vent, the boot, and the first several feet of ductwork behind it.
Air Duct Repair in Deale
Air Duct Repair in Deale addresses the specific damage this environment causes: corroded metal seams, disconnected flex duct in crawl spaces, and leaks in original ductwork that let humid attic air mix with conditioned air. Typical repairs in Deale range from $200 – $500 for sealing and patching to $800 – $1,500 for section replacement in older homes with extensive corrosion. We also handle Duct Sealing in Deale for homes where the ductwork is intact but leaking at joints.
Corrosion Damage from Salt Air
Deale’s proximity to the Chesapeake Bay means salt air accelerates rust on galvanized ductwork. We’ve opened crawl spaces on Rockhold Creek where the trunk line looked fine from the outside but had pinhole leaks across the bottom. We patch what can be saved and replace what can’t, always with written pricing before cutting anything.
Moisture Intrusion Repairs
Humid subtropical summers push moisture into duct systems through every gap. In vacation rentals that sit empty, that moisture breeds mold. We repair the entry points, treat affected areas with antimicrobial solution, and document the work with before-and-after photos so owners have proof the job was done.
Trusted Brands We Service in Deale
We run professional-grade equipment because Deale’s conditions demand it. Our rotary brush systems come from Rotobrush, our negative-air machines from Nikro, and our filtration products from Honeywell and Aprilaire. These aren’t hardware-store tools. A Nikro negative-air machine pulls 2,000+ CFM, which is what you need to extract heavy mold debris without letting it escape into the house. Honeywell and Aprilaire filtration components are stocked for Deale customers who want to upgrade their system after cleaning. When a Deale homeowner calls about a musty smell or restricted airflow, we arrive with equipment that matches the problem, not a shop vac with a long hose.
Common Air Duct Cleaning Problems We See in Deale Homes
- Mold and mildew in seasonal rental ducts. Homes on Deale Beach Road and the surrounding water-privileged areas often sit vacant October through April. Without airflow, humidity condenses inside the ductwork, and by spring opening, we’re called to clean visible mold from vents that looked fine in September.
- Salt-air corrosion on metal components. The Chesapeake Bay’s salt air doesn’t just affect boats. We’ve replaced corroded register screws, rusted vent boots, and deteriorating trunk lines in cottages that never had this problem until their fifth or sixth year near the water.
- Poorly sealed flex duct in newer construction. Townhomes and single-family homes built in the 2000s often use flex duct that saves money upfront but traps moisture if the vapor barrier is compromised. Deale’s humidity makes this worse than in drier inland counties.
- Leaky original ductwork in waterfront cottages. The older housing stock on Franklin Gibson Road and similar areas has ductwork from the 1960s – 80s with joints sealed by failing tape or mastic. Every leak pulls hot, humid attic air into the system, making the HVAC work harder and the ducts dirtier.

Yes, we work throughout Deale, from the cottages on Rockhold Creek and Deale Beach Road to the townhomes off Route 256 and the single-family homes near Franklin Gibson Road. The waterfront properties actually need us most because of the salt-air corrosion and seasonal vacancy issues.
We don’t advertise emergency dispatch for duct cleaning because it’s a scheduled maintenance job, not an urgent repair. However, our phones are answered live 24/7, and if you’re dealing with a situation like visible mold before a rental season opens or a system failure tied to duct blockage, we’ll prioritize scheduling to get a crew to Deale as soon as possible.
Deale pricing is comparable to Edgewater and Riva for standard jobs, but Deale’s waterfront homes sometimes need additional antimicrobial treatment or corrosion repair that inland homes don’t. We price each job individually after inspection, and we write that price down before starting.
Every Deale job is covered by our 365-Day Done Right Promise in writing. If the cleaning fails to resolve the issue within a year, or if a repair we made fails, we return and make it right at no charge, including a free second visit. Most duct cleaning companies in the area don’t put a one-year guarantee in writing. We do, on every job.
