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 Annapolis
Air duct cleaning in Annapolis typically runs $350-$650 for a full residential system, with most homes falling in the $450-$550 range depending on duct layout and contamination level. Our Air Duct Cleaning team dispatches from our Baltimore office and serves Annapolis homeowners directly, bringing equipment built for the specific problems this coastal city creates: salt-driven corrosion, chronic humidity, and the mold colonies that follow.
We’ve worked in Annapolis long enough to know the difference between a duct system in Parole and one in the Historic District. The 18th-century row houses near State Circle have ducts crammed into chases that were never meant to carry air. The 1970s colonials off Forest Drive have flex duct that’s been cooking in bay humidity for forty-plus years. And in Eastport, we’ve learned to check crawl-space runs first, because tidal flooding there isn’t theoretical, it’s a calendar event. When you call (469) 972-3151, you’ll reach a live person who understands Annapolis housing stock and can give you a written estimate before any work starts.
Why Kestrel Air Duct Cleaning Is Annapolis’s Preferred Air Duct Cleaning Company
Our reputation in Annapolis was built job by job, not by buying reviews. Homeowners here talk to each other, they know which companies show up in the window they promised and which ones don’t. We’ve earned that trust by following The Kingswell Way on every visit: say the price upfront, arrive when we said we would, leave the place cleaner than we found it, and put our 365-Day Done Right Promise in writing. If the work falls short within that year, we come back and make it right at no charge. That’s not a courtesy we extend when we feel like it. It’s a written commitment on every single invoice.
Our technicians are background-checked, uniformed, and trained on the equipment that actually removes contamination, not just moves it around. We use Rotobrush rotary brush systems to dislodge debris caked on duct walls, Nikro negative-pressure units to pull that loosened material out of your system entirely, and Abatement Technologies HEPA filtration so the particles we remove don’t settle back into your living space during cleaning. These aren’t shop vacs from a hardware store. They’re professional tools for professional results.
Calls to (469) 972-3151 are answered by a live person, 24 hours a day. No automated queue, no callback roulette. When you’re dealing with musty air after a humid Annapolis summer or you’re concerned about what a recent flood might have left in your crawl space, you want to talk to someone who can schedule you, not a machine that promises to “listen carefully to our menu options.”
Air Duct Repair in Annapolis
Air Duct Repair in Annapolis addresses the physical damage that humidity, salt air, and age inflict on duct systems before contamination spreads to every room in your house. We repair separated flex duct, corroded metal connections, crushed supply runs, and compromised return chases, with most residential repairs in Annapolis running $200-$500 for standard fixes and $600-$1,200 for extensive corrosion replacement or chase reconstruction in older homes.
Corrosion Repair from Salt Air Exposure
Annapolis’s Chesapeake Bay location means salt-laden air accelerates oxidation of metal duct components and registers faster than anywhere inland. We replace corroded collar connections, rusted dampers, and pitted supply boots with materials rated for coastal environments, then seal joints with mastic rather than foil tape that degrades in humidity.
Flex Duct Replacement in Tight Chases
The aging flex duct in Parole and West Annapolis homes often separates at connections or sags into insulation, creating dead zones where moisture pools. We pull new flex through existing chases where possible, or fabricate custom sheet-metal transitions when the original installation left no access. Every repair gets camera-verified before we close up.
Ductwork Cleaning in Annapolis
Ductwork Cleaning in Annapolis removes accumulated debris, mold colonies, and biological contamination from your entire HVAC distribution system, not just the vents you can see. A full system cleaning for a typical Annapolis home runs $350-$650, with larger homes or systems with substantial contamination reaching $750-$950. This covers all supply ducts, return ducts, the main trunk line, and the air handler cabinet.
Source Removal vs. Surface Masking
We perform source removal using mechanical agitation and negative-air extraction, which means we physically dislodge debris and pull it out of your home. This is fundamentally different from fogging “sanitiser” treatments that coat duct surfaces with chemicals but leave the actual contamination in place. Fogging might smell clean for a week. It doesn’t remove saturated fiberglass liner or standing moisture in crawl-space runs.
Post-Flood Remediation Protocol
After tidal surge events in Eastport or nuisance flooding in the lower Historic District, we inspect crawl-space and basement mechanical systems before standard cleaning. Saturated duct liner must be removed, not cleaned. Metal components get corrosion assessment. We document everything with video inspection so you know exactly what was found and what was done.
Trusted Brands We Service in Annapolis
We clean and maintain duct systems connected to all major HVAC brands, and we stock filtration products from Aprilaire, Guardsman, and Abatement Technologies for Annapolis homeowners who want to maintain cleaner air between service visits. Aprilaire media air cleaners capture particles down to one micron, which matters in a city where pollen, mold spores, and salt particulates all compete for space in your air. Guardsman UV-C systems install directly in the air handler to inhibit microbial growth on wet coils, a genuine help in Annapolis’s humidity. We keep common sizes in stock so turnaround is fast, and we size everything to your actual system rather than selling you a filter that “fits most.” If you’re not sure what your system needs, we’ll check the specs during your cleaning and give you options with prices in writing.
Common Air Duct Cleaning Problems We See in Annapolis Homes
- Active mold in crawl-space flex runs. The combination of Annapolis’s 70%+ average relative humidity and tidal moisture intrusion in low-lying neighborhoods creates perfect conditions for black mold colonization in fiberglass duct liner. We find it regularly in Eastport and the Historic District, and it doesn’t respond to surface cleaning.
- Corroded metal components from salt air. Supply registers, trunk-line seams, and damper hardware oxidize faster here than in Frederick or Hagerstown. The corrosion isn’t just cosmetic, it creates air leaks that waste energy and pull unfiltered crawl-space air into your system.
- Compressed or degraded flex duct in 1970s-1990s homes. The colonial-revival tract homes in Parole and Epping Forest were built with flex duct that’s now past its functional lifespan. The inner liner tears, the insulation gets wet and collapses, and airflow drops by 30% or more before homeowners notice.
- Debris accumulation in irregular Historic District chases. Ductwork retrofitted into 18th- and 19th-century structures often follows paths with multiple 90-degree turns and no cleanout ports. A quick pass misses debris packed in corners; only rotary brush agitation and sustained negative pressure pull it free.
Pricing for Air Duct Cleaning in Annapolis, MD
Most full residential duct cleanings in Annapolis run $450-$550. Smaller homes with straightforward systems sometimes come in around $350-$400. Larger homes with multiple zones, substantial contamination, or difficult access (tight Historic District chases, extensive crawl-space work) can reach $650-$950. Commercial systems are priced per system after on-site evaluation.
What moves you within that range: the number of supply and return vents, whether your system includes a main trunk and branch layout or a simpler radial design, the degree of contamination (light dust vs. heavy mold or construction debris), and access difficulty. We give you one flat price per system, agreed in writing before we touch a single vent. No per-vent add-ons. No “we found an extra problem” charges at the door. The price we write down is the price you pay.
We also provide before-and-after photos of your own ducts, not stock images. You’ll see what came out, and you’ll know the work was real. Call (469) 972-3151 for a free estimate. Estimates take about ten minutes and carry no obligation.

FAQs About Air Duct Cleaning in Annapolis
Annapolis’s position on the Chesapeake Bay at the mouth of the Severn River produces consistently higher relative humidity and salt-laden air than inland cities like Frederick or Hagerstown, which accelerates mold growth and metal corrosion inside duct systems year-round. Most Annapolis homeowners benefit from inspection every two to three years, and homes in flood-prone areas like Eastport may need more frequent evaluation. Call (469) 972-3151 to schedule a free assessment and we’ll tell you what your specific system needs.
Fogging does not remove mold; it applies a chemical coating that may suppress odor temporarily while leaving the actual contamination, including saturated fiberglass liner and active colonies, in place. For genuine mold remediation in Annapolis’s humid environment, you need mechanical source removal: rotary brush agitation to dislodge growth, negative-air extraction to pull it out, and HEPA filtration to protect your living space during the process. Call (469) 972-3151 and we’ll show you the difference with before-and-after photos of your own system.
Check crawl-space flex runs and basement mechanical rooms first; tidal surge introduces moisture directly into these spaces, and saturated duct liner must be removed rather than cleaned. Our post-flood protocol includes video inspection of all affected runs, moisture metering of remaining components, corrosion assessment of metal parts, and replacement of any water-damaged materials before standard cleaning begins. Call (469) 972-3151 immediately after flooding; delaying inspection lets mold establish colonies that are harder and more expensive to address.
Yes, though it requires specialized equipment and patience that shop-vac operators typically don’t bring. Historic District ductwork was retrofitted into spaces never designed for HVAC, with tight turns and no cleanout ports. We use flexible rotary brush heads on extended shafts, combined with portable negative-pressure units that fit in confined spaces, to achieve thorough agitation and extraction without damaging original plaster or woodwork. Camera inspection confirms the results before we finish.
Salt air accelerates oxidation of supply registers, trunk-line seams, damper hardware, and collar connections, creating air leaks that pull unfiltered crawl-space or attic air into your system and waste conditioned air. We assess corrosion during every cleaning and repair or replace compromised metal with materials rated for coastal exposure, sealed with mastic that won’t degrade in humidity. The damage happens faster here than inland; catching it early prevents the energy waste and contamination that follows.
