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 Hempstead
Air duct cleaning in Hempstead typically runs $350 – $650 for a full residential system, with most jobs completed in a single visit. We dispatch crews to Hempstead from our New York City office, and we know the village’s streets well enough to hit our arrival windows, whether we’re working off Peninsula Boulevard or down in the tree-lined blocks near Hofstra University. Roy Castellanos and our team have spent years in Hempstead’s mid-century capes and colonials, and we’ve learned that ductwork here isn’t like what you’ll find in newer construction. The original galvanized steel and early flexible ducts installed from the 1920s through the 1970s need a different approach than a routine maintenance clean. Call (361) 326-5060 for a free estimate, and we’ll give you a written price before any work starts.
Why Hollis Air Duct Cleaning Is Hempstead’s Preferred Air Duct Cleaning Company
We’ve been part of the Garrison Partners family since 2004, and our Air Duct Cleaning team has built a reputation in Hempstead by showing up on time, pricing in writing, and leaving the site clean. Our technicians are background-checked and uniformed, and they follow The Garrison Code on every job: arrive inside the window, explain what they found, get approval on a written price, then do the work by the book.
Hempstead homeowners call us back because we don’t treat a 1950s cape like a 2005 colonial. We know the original ductwork in these homes was installed with minimal filtering, so we come prepared with rotary brush systems and negative-air machines that can handle decades of accumulation, not just surface dust. 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.

Air Duct Cleaning Services in Hempstead
Air Duct Cleaning Services in Hempstead are restoration work as much as routine maintenance. Most homes here were built between 1920 and 1970 with forced-air systems using original galvanized steel or early flexible ducts. Those materials collect debris and moisture in basement and crawlspace runs that newer systems simply don’t have. Our process starts with a video inspection so you see what we’re seeing, then we use Rotobrush rotary brush agitation combined with Nikro negative-air HEPA filtration to source-remove buildup without pushing it back into your living space. A typical residential air duct cleaning in Hempstead runs $350 – $550 for a standard cape or colonial, with larger homes or systems requiring access panel installation running toward the $650 end.
Supply Duct Cleaning
Supply ducts carry heated or cooled air from your air handler to each room. In Hempstead’s older homes, we often find these runs partially blocked by rust flakes from corroded galvanized steel, or by collapsed sections of early flexible duct that have degraded in hot crawlspaces. We clean each supply branch individually, then test airflow at the register to confirm the run is delivering what it should.
Return Duct Cleaning
Return ducts pull air back to the air handler for reconditioning. These larger trunk lines are where the heaviest accumulation hides in Hempstead homes, especially in capes with basement returns that have never been opened. We cut access panels where needed, run mechanical agitation tools the full length of the trunk, and seal every opening with mastic when we’re done.

HVAC Duct Cleaning in Hempstead
HVAC Duct Cleaning in Hempstead addresses the full heating and cooling system, not just the visible registers. This matters here because the village’s humid summers and cold winters create ideal conditions for mold and dust mites in ductwork, while spring pollen from abundant local trees infiltrates systems and recirculates indoors. The proximity to the Atlantic also means salt air can accelerate corrosion in older metal ducts. Our HVAC duct cleaning process includes the air handler cabinet, blower assembly, and evaporator coil where accessible, plus the complete supply and return network. Pricing for full HVAC duct cleaning in Hempstead typically runs $450 – $650, depending on system size and whether we find disconnected or corroded runs that need sealing or replacement.
Full System Cleaning with Video Inspection
We start every HVAC duct cleaning with a camera run so you see the condition of your ducts before we touch them. In Hempstead, this often reveals crushed flex ducts behind finished basement ceilings, rusted seams in galvanized trunks, or construction debris from decades-old renovations. The video becomes your baseline, and we run it again after cleaning so you can verify the results.
Duct Sealing and Restoration
Cleaning alone doesn’t fix a rusted-through seam or a disconnected branch duct. After we remove the debris load, we evaluate whether your system needs mastic sealing, access panel installation, or section replacement. We price this work in writing before we start, and we only recommend what the inspection actually shows.
Trusted Brands We Service in Hempstead
Our equipment roster includes Rotobrush rotary brush systems and Nikro negative-air machines for the cleaning itself, plus filtration and sealing products from Honeywell, Aprilaire, and Abatement Technologies. These are the same tools commercial crews use, not hardware-store gear, and we stock common parts so Hempstead customers aren’t waiting on shipping for standard repairs. If your system needs a filtration upgrade after cleaning, we’ll show you the Aprilaire or Honeywell options that fit your air handler and explain what each one does for the air moving through your home.
Common Air Duct Cleaning Problems We See in Hempstead Homes
- Decades of accumulated debris in original galvanized trunks. In many Hempstead capes, the original ductwork was installed with minimal filtering, so technicians often find decades of accumulated dust, pet dander, and even construction debris from past renovations. This requires thorough manual cleaning before any mechanical equipment is used.
- Salt-air corrosion on South Shore-adjacent streets. Hempstead’s mid-century capes were built with galvanized steel supply trunk lines and early flexible branch runs that are now 50 – 80 years old, and the salt air coming off the South Shore corrodes that metal from the inside. We routinely find rust-flaked duct interiors that no amount of shop-vac cleaning will fix without sealing or replacing the affected run.
- Crushed or disconnected flexible branch ducts behind finished ceilings. Contractors skip camera inspection and miss these failures, so the system keeps running but half the supply air dumps into the joist bay. We find this regularly in Hempstead basements that were finished over original duct runs.
- Mold and dust mite colonies from humidity cycling. Hempstead’s humid summers and cold winters create condensation in unheated crawlspace duct runs, and the microbial growth that follows gets blown into living spaces every time the fan cycles. Cleaning removes the colony; sealing prevents it from returning.
Pricing for Air Duct Cleaning in Hempstead, NY
We give honest whole-system pricing, not per-vent teaser rates that balloon at the door. A typical residential air duct cleaning in Hempstead runs $350 – $550 for a standard cape or colonial with 8 – 12 registers. Larger homes, systems requiring access panel installation, or jobs that need full HVAC duct cleaning including the air handler run $450 – $650. Commercial systems are priced by square footage and system complexity, typically starting around $800.
What moves the price: the number of supply and return runs, whether we need to cut access panels in ductwork that has never been opened, the condition of the original material (rusted or damaged sections need sealing or replacement), and whether the job includes the air handler and coil. We inspect first, write the price down, and get your approval before any work begins. Estimates are free. Call (361) 326-5060.

FAQs About Air Duct Cleaning in Hempstead
The musty smell comes from microbial growth in your ductwork, usually in unheated crawlspace or basement runs where summer humidity has condensed on dust-laden duct surfaces. In Hempstead’s mid-century capes, the original galvanized steel trunks and early flexible branch ducts create pockets where moisture and debris combine. We remove the growth source with mechanical agitation and negative-air HEPA extraction, then seal any rusted seams that would let it return. Call (361) 326-5060 for a free inspection.
Yes, if your system was installed without cleanout openings, which is common in Hempstead homes built before 1970. The original ductwork in these capes and colonials was never designed for maintenance access, so we cut precision access panels in the trunk lines, clean the full interior, and seal the openings with mastic-backed panels that maintain system pressure. We include this in your written price before we start.
Air duct cleaning covers the supply and return duct network; HVAC duct cleaning adds the air handler cabinet, blower assembly, and evaporator coil where accessible. For older Hempstead systems, we usually recommend HVAC duct cleaning because the same blower that moves air through your ducts also recirculates whatever is growing on the coil or in the cabinet. The combined service runs $450 – $650 versus $350 – $550 for ducts alone.
Yes, we find crushed or disconnected flexible branch ducts in Hempstead basements regularly, especially in homes where the basement was finished over original duct runs. Early flexible duct material degrades over decades, and the weight of ceiling materials or simple foot traffic in storage areas can collapse it. Our video inspection catches this before we quote, and we repair or replace damaged sections as part of the job.
Hempstead’s abundant tree cover means heavy spring pollen loads that infiltrate ductwork through gaps and recirculate indoors, while South Shore salt air accelerates corrosion in older metal ducts. Most Hempstead homeowners benefit from cleaning every 3 – 5 years, but homes with original galvanized steel or visible rust may need inspection every 2 – 3 years to catch corrosion before it breaches the duct wall. Call (361) 326-5060 and we’ll assess your specific system.
