Trusted Air Duct Cleaning for Hempstead Homeowners
Most Hempstead homes have ductwork that hasn’t been opened since the day it was installed. That means years of dust, pet dander, and construction debris moving through the air your family breathes every day. We’ve been cleaning air ducts in Hempstead since 2004, and the difference after a proper cleaning is immediate: less dust settling on furniture, better airflow from your vents, and a system that doesn’t have to work as hard to heat or cool your home. Roy Castellanos and the team at Hollis Air Duct Hempstead do this work by the book, with written pricing before we start and a 365-Day Done Right Promise behind every job. Call (516) 559-4917 for a free estimate.
We’re part of the Garrison Partners family, independently owned and operated right here on Long Island. Every technician who walks through your door is background-checked, uniformed, and held to The Garrison Code: arrive inside the quoted window, price in writing before work begins, do the job by the book, and leave the site clean. No bait-and-switch, no surprise add-ons, no mess left behind.
We answer the phone with a live person 24 hours a day, 7 days a week. That matters when you’re trying to figure out whether the smell coming from your vents is normal or whether it’s time to get someone in. It matters when you need a straight answer about cost before you commit. And it matters when another company put you on hold for 20 minutes and then never called back.
Air Duct Cleaning Services
Air Duct Cleaning Services cover the full scope of work needed to remove built-up debris from the ducts that carry heated and cooled air through your Hempstead home. Most homes need this every 3 to 5 years, but homes with pets, recent renovations, or family members with allergies often benefit from more frequent service. We use professional-grade negative-air machines from Nikro and rotary brush systems from Rotobrush to loosen and extract what’s accumulated inside your ductwork. Whole-home air duct cleaning in Hempstead typically runs $350 to $600 for a single system, depending on home size and the number of registers. Every job gets a written price before we touch anything.
Full-System Negative-Air Cleaning
The negative-air method puts your entire duct system under vacuum while rotating brushes agitate the interior walls of each duct run. Built-up dust and debris get pulled into a HEPA-filtered collection unit, not blown back into your living space. We’ll cover supply registers, return vents, the main trunk lines, and the branch lines that feed each room.
Post-Construction Duct Cleanup
If you’ve had drywall work, flooring replaced, or any renovation in Hempstead, construction dust ends up in your ducts whether the contractor taped off the registers or not. We see it constantly: sawdust and drywall fines that keep recirculating through the house for months. We clean the full system and replace the air filter so you’re not breathing job-site dust long after the crew left.

HVAC Duct Cleaning
HVAC Duct Cleaning addresses the ductwork connected to your heating and cooling equipment specifically as part of the larger HVAC system, not just the vent openings you can see. When your HVAC blower runs, it pushes air across the evaporator coil and through every duct run in the house. Anything sitting in those ducts gets stirred into that airflow. In Hempstead, where summer humidity keeps AC systems running hard and winter heating pushes warm air through the same runs, duct interiors collect a mix of dust, pollen, and condensation-driven buildup. HVAC duct cleaning from Hollis Air Duct Hempstead costs $350 to $600 for a typical single-family home. We also inspect the duct connections at the air handler and registers while we’re in there, so you get a full picture of what’s happening behind your walls.
Supply and Return Airflow Restoration
Restricted airflow makes your HVAC system work harder to hit the thermostat setting, which shows up as higher utility bills and uneven room temperatures. When we clean the supply and return sides of your system, we check static pressure before and after the job. You can actually feel the difference at the registers, and we’ll show you what came out of the ducts with before-and-after photos.
Evaporator Coil and Blower Cleaning
The coil above your furnace or air handler is a magnet for what the filter doesn’t catch. A dirty coil reduces cooling capacity and can freeze up in summer. While your duct system is open, we clean the accessible surfaces of the coil and blower assembly using professional-grade equipment. It’s part of treating the HVAC system as a whole rather than just vacuuming the vents.
Vent Cleaning
Vent Cleaning is the portion of the job that focuses on the register openings, grilles, and the first several feet of ductwork behind them, the parts you can see and reach from the living space. It’s what most Hempstead homeowners notice first: dust streaks on the wall above a register, a gray film building up on vent louvers, or a musty smell when the system kicks on. Vent cleaning alone does not replace a full negative-air duct cleaning, but it’s an important part of the complete service, and sometimes a homeowner wants just the visible openings addressed between full cleanings. Vent cleaning as a standalone service runs $150 to $300 in Hempstead depending on the number of registers and whether they’re wall, floor, or ceiling mounted.
Register and Grille Restoration
We remove each register and grille, clean the louvers on both sides, and wipe down what’s behind them. Years of kitchen grease, hair spray, and candle soot build up on these surfaces and restrict airflow. When they go back in, they’re clean and the airflow immediately improves.
Visible Duct Run Cleaning
From each register opening, we can reach several feet into the duct run with professional agitation tools and vacuum extraction. This addresses the debris that collects right at the opening, where dust tends to settle after the system shuts off. It’s a targeted service, and we’ll be straightforward about whether your home would benefit more from a Full System Cleaning instead.
Air Duct Repair
Air Duct Repair addresses ducts that have separated, crushed, or developed holes, any of which pulls conditioned air out of the system and into unconditioned spaces like attics and crawl spaces. In Hempstead homes, we regularly find disconnected duct runs in attics where someone pushed through to run cable or store boxes and knocked a joint loose. Air duct repair from Hollis Air Duct Hempstead typically runs $150 to $400 per repair point, depending on access and what’s needed to reseal or replace the section. Every repair is covered by the 365-Day Done Right Promise, which means if it fails within a year, we come back and make it right at no charge, including a free second visit.
Duct Sealing with Mastic
We use duct sealing mastic, a thick paste applied with a brush, to close gaps at joints and connections. It cures to a durable, airtight seal that doesn’t peel like tape. This is the same material commercial HVAC crews use, and it’s the right tool for residential systems too, especially on metal ductwork in attics and basements.
Disconnected or Crushed Duct Repair
When a duct run has pulled apart or collapsed under its own weight, we reconnect and reroute the section properly, adding support straps where needed. A single disconnected run can mean one room never gets comfortable, no matter how hard the system runs. After the repair, we test airflow at the register to confirm the fix took.
Ductwork Cleaning
Ductwork Cleaning is the mechanical process of cleaning the entire network of ducts, trunk lines, and branch runs that distribute air through your home, not just the sections you can see. The distinction matters: vent cleaning deals with the openings, while ductwork cleaning goes deep into the system where the buildup actually lives. We use a combination of pneumatic agitation and negative-air extraction, with HEPA filtration on the collection side so nothing we pull out ends up back in your home. Ductwork cleaning for a typical Hempstead ranch or colonial costs $350 to $600. Larger homes or homes with multiple zones run higher, and we’ll confirm the exact price in writing before any work starts.
Rotary Brush Agitation
A Rotobrush rotary brush system spins inside the duct while traveling through each run, knocking loose the layer of dust and debris stuck to the interior surface. The rotating action reaches what simple vacuum pressure leaves behind. Combined with negative air, it’s the most effective method we’ve used in 20 years of cleaning ducts on Long Island.
HEPA-Filtered Extraction
Our extraction units capture the loosened debris before it has any chance to escape into your home. HEPA filtration means the air leaving the vacuum unit is cleaner than the air in most houses. It’s the same requirement hospitals and labs apply to their air handling, applied to your Hempstead living room.
Air Duct Inspection
Air Duct Inspection is a camera-based look inside your ductwork to document what’s actually there before anyone recommends a service. We don’t sell cleaning without first seeing what’s inside. In Hempstead homes, inspections commonly turn up dust accumulation, mold spots from condensation, debris from renovations, and occasionally rodent activity in attic duct runs. An air duct inspection from Hollis Air Duct Hempstead is included with every cleaning estimate, so you see what we see before you spend a dollar. If you want a standalone inspection with a report, it’s $100 to $200.
Pre-Cleaning Camera Assessment
We push a small camera into the main trunk line and several branch runs to see the interior condition before we quote the job. You watch the footage in real time and see the extent of buildup. It takes the guesswork out of whether cleaning is actually warranted.
Post-Cleaning Verification
After the cleaning is done, we run the camera again so you can compare before and after from the same points in the system. The visual proof is part of why our customers feel confident the job is complete. No vague “it should be better now” from us.
Residential Air Duct Cleaning
Residential Duct Cleaning is our bread-and-butter work in Hempstead: cleaning the ducts in single-family homes, apartments, condos, and co-ops where people sleep and eat and need clean air. The homes here range from 1920s center-hall colonials near Hofstra to mid-century ranches and newer center-island builds, and the duct layouts vary just as much. Residential air duct cleaning runs $350 to $600 for a standard home, and we bring the same commercial-grade equipment to a small condo as we do to a large colonial. The process is the same: written price, negative-air extraction, before-and-after documentation, and a 365-Day Done Right Promise on the whole scope.
Multi-Zone and Split-Level Homes
Multi-zone systems mean separate sets of dampers and sometimes separate trunk lines. We clean each zone thoroughly, not just the main level, which keeps the upstairs and downstairs equally clean. A single missed zone is a common complaint we hear from customers who tried another company first.
Allergy and Pet Households
If anyone in your home manages allergies or asthma, duct cleaning has a measurable impact because it removes the reservoir of dust and dander that recirculates every time the blower runs. We can’t remove allergens from the ecosystem of your house, but we can remove the pound of dust sitting in the ducts and keep it from recirculating. We’ll also recommend the right filter, using products from Honeywell and Aprilaire where appropriate.
Commercial Air Duct Cleaning
Commercial Duct Cleaning serves the businesses, offices, storefronts, and light industrial spaces in Hempstead and the surrounding Long Island towns. Commercial systems are larger, run longer hours, and often go longer between cleanings, so the buildup is usually heavier. Pricing for commercial duct cleaning starts around $500 for a small office suite and goes up based on square footage, rooftop unit count, and the complexity of the duct layout. We service offices on Main Street, medical and dental practices, retail stores, salons, and multi-tenant buildings. Work can be scheduled after hours to avoid disrupting business operations.
Retail and Office Spaces
Storefronts and offices with regular foot traffic bring in dust and debris from outside, and duct systems compound the problem. We’ll work around your business hours, set up containment so the work doesn’t spread dust through your space, and document everything before and after. The Garrison Standard applies to commercial jobs the same as residential: show up when promised, price in writing, leave the site clean.
Medical and Dental Offices
Medical environments have specific air quality concerns, and regular duct cleaning is part of good facility management. We use HEPA-filtered negative-air equipment and follow strict containment procedures during the work. We do not claim any medical-specific certifications beyond standard commercial-grade cleaning, but our process meets the practical air quality expectations of a professional office environment.

AfterBrands We Service
Whether your home has a forced-air furnace, a heat pump, or a central air handler, the ductwork connected to it is what we clean, regardless of brand. We work on systems from every major manufacturer, and our technicians are trained on the equipment that matters to the job at hand.
On the HVAC side, we service and clean duct systems connected to Honeywell and Aprilaire filtration setups, and we stock the common filter replacements for those brands to save you a trip to the supply house. We also use Abatement Technologies equipment in certain commercial and heavy-duty residential jobs where extraction demands are higher. The negative-air machines from Nikro are our everyday workhorses in Hempstead homes. If your system runs on any other make, we can help with that too.
Signs You Need a Pro Right Now
- Dust returning within days of cleaning. If you dust your furniture on Sunday and by Wednesday there’s a fresh film, your ducts are likely recirculating it. The dust is coming from somewhere, and in most Hempstead homes, the ductwork is the reservoir.
- Rooms that stay hot in summer or cold in winter. When one room never gets comfortable while the rest of the house is fine, the problem is often a disconnected or crushed duct run. It’s a physical issue we can find with an inspection and fix with proper duct repair.
- Musty smell when the system turns on. That odor is trapped organic material and condensation byproducts in the ductwork. It gets pushed into the living space every time the blower kicks on. Cleaning removes the source, not just the smell.
- Visible mold or staining around registers. Dark marks around supply vents can indicate moisture in the ductwork, which is the precursor to mold growth. If you see this, get an inspection sooner rather than later.
- Family members with unexplained allergy symptoms at home. If symptoms ease when you leave the house and worsen when you return, the HVAC system is a likely culprit. Duct cleaning removes the particulate load, and we’ll recommend the right filtration setup from Honeywell or Aprilaire for your home.
Our Process, Step by Step
- 1
Camera inspection and written quote. We arrive inside the scheduled window, walk the system with you, and push a camera into the trunk line so you see the condition of your ducts before we quote anything. The price is written down, and it does not move.
- 2
System preparation and containment. We cover work areas, protect the floor, and determine which registers need to be sealed off so no dust escapes during extraction. The blower gets shut down, and all vents are opened for access.
- 3
Rotary brush agitation and negative-air extraction. Our Rotobrush system agitates the duct interior while the Nikro negative-air machine pulls loosened debris into a HEPA-filtered collection unit. Supply ducts, return ducts, trunk lines, and branch runs all get the same treatment.
- 4
Component attention and filter replacement. While the system is open, we clean accessible fittings, check connections, and install a new filter. We’ll let you know what level of filtration makes sense for your home and whether the coil needs attention.
- 5
Post-cleaning walkthrough and verification. We run the camera again so you can compare before and after, confirm airflow at each register, and leave the site clean. If anything fails within the year, the 365-Day Done Right Promise covers a return visit at no charge.
How Much Does Air Duct Cleaning Cost in Hempstead?
A typical whole-home air duct cleaning in Hempstead runs $350 to $600 for a single system in a standard single-family home. Smaller condos or apartments with fewer registers can come in under $350. Larger homes with multiple zones, basement trunk lines, and attic systems run higher, typically $500 to $800. Standalone vent cleaning runs $150 to $300. Air duct repair work runs $150 to $400 per point, depending on access and the extent of the damage. A standalone air duct inspection is $100 to $200, and it’s included free with any cleaning estimate.
What affects the price: number of registers and returns, total linear feet of ductwork, number of floors, system type (forced air vs. wall unit vs. commercial rooftop), accessibility of trunk lines, and the level of buildup. A system that hasn’t been cleaned in 15 years takes longer than one cleaned 3 years ago.
How to avoid overpaying: get a written price before work starts, ask whether the quote covers the full system or just the vents, and ask for before-and-after documentation. Our price is written down before we touch anything, and it covers the whole system, not per-vent pricing that looks cheap on paper and balloons when the job starts. Every estimate includes a camera inspection so you see what you’re paying for.
A free estimate from Hollis Air Duct Hempstead includes the full inspection, a written quote, and our recommendations in plain English. No pressure, no same-day sales pitch, no numbers that change when the van arrives.

Frequently Asked Questions About Air Duct Cleaning in Hempstead
Air duct cleaning is the process of removing accumulated dust, debris, and contaminants from the interior of the ductwork that carries air through your home.
