Fast, Reliable Air Duct Cleaning Across Hempstead
Air duct cleaning in Hempstead starts with an honest look at what’s actually inside your ducts. For most homes here, built between the 1940s and 1970s, that means decades of dust, oil-based heating residue, and often a disconnected or crushed run no one’s ever seen. We find it, show it to you on video, and fix it before we clean. Our Air Duct Cleaning team serves Hempstead with written pricing before any work starts and a 365-Day Done Right Promise backing every job. Call (516) 559-4917 for a free estimate.

Why Hollis Air Duct Hempstead Is Hempstead’s Preferred Air Duct Cleaning Company
Hempstead homeowners call us because the houses here present problems newer subdivisions don’t. Original ductwork squeezed into narrow basements, supply runs that have settled out of alignment over 60 or 70 years, and return ducts pulling air from crawlspaces instead of rooms. We know what that looks like because we’ve opened enough of these systems to recognize the patterns. Roy Castellanos leads our Hempstead crew, and every technician who walks through your door is background-checked and uniformed.
We don’t do bait pricing. The number we write down before work begins is the number you pay. Our Hempstead customers regularly tell us the video inspection alone was worth the call, because for the first time they could see what was actually happening inside their walls. We arrive inside the quoted window, work by The Garrison Code, and leave the site cleaner than we found it.
Part of the Garrison Partners family since 2004, Hollis Air Duct Hempstead operates on The Garrison Standard: written prices, written guarantees, and answering the phone when you call. Twenty-four hours a day, seven days a week, a live person picks up. No voicemail loops.
Styles & brands we work with




Vent Cleaning in Hempstead
Vent cleaning in Hempstead usually means more than pulling a brush through a register. The supply vents in these older homes have been collecting forced-air furnace residue since the Johnson administration. Oil-based film bakes onto the duct walls and standard brushing simply skates over it. We run HEPA-filtered negative-air machines with agitation tools that actually break that film loose, then capture it before it ever reaches your living room air.
Supply and Return Vent Access
Many Hempstead homes have original floor registers with narrow boots that limit tool access. Our technicians work with low-profile agitation heads designed for exactly this situation, and we photograph every vent before and after. You see what we cleaned.
When Hempstead Homeowners Need Vent Cleaning
If you can see dust buildup on the register fins, smell a musty odor when the blower kicks on, or notice one room never seems to heat or cool properly, the vents are telling you something. A full vent and system cleaning in Hempstead typically runs $450 to $750 for an average single-family home, depending on the number of returns and system configuration.
Air Duct Repair in Hempstead
Air duct repair in Hempstead is where we spend a surprising amount of our time, and it’s the step cheap cleaning companies skip entirely. They’ll hook a vacuum to your system and call it done while your return duct is pulling crawlspace air through a tear the size of a dinner plate. We repair first, clean second. That’s the order that actually changes your indoor air.
Crushed and Disconnected Runs
Compact basements and decades of settling mean duct runs in Hempstead get crushed, kinked, or knocked loose from their boots. A disconnected return means your furnace is pulling air from wherever it sits, not from your living spaces. We locate these failures with a video inspection, then make the repair with sheet-metal splices, proper hangers, and mastic-sealed seams. Repair work like this typically runs $180 to $400 per run depending on access and extent of damage.
Sealing Before Cleaning
We never run a negative-air cleaning without first inspecting and sealing accessible ductwork. Otherwise the vacuum is pulling basement air instead of loosening the debris inside your runs. That’s not cleaning. That’s theater. In Hempstead, Duct Sealing in Hempstead is often the real fix, and it’s included in our assessment before we ever turn a machine on.

Trusted Brands We Service in Hempstead
Our equipment roster matters because the job requires the right tool for the material. We run Nikro negative-air machines for source-removal cleaning, paired with HEPA filtration from Abatement Technologies. For homes with central filtration already in place, we service and integrate Honeywell and Aprilaire media cabinets, plus Lennox in Hempstead systems. We keep common filter sizes and sealing materials stocked for fast turnaround on Hempstead jobs, which means less waiting when a repair requires parts.

AfterCommon Air Duct Cleaning Problems We See in Hempstead Homes
- Disconnected return ducts under slabs. In older split-levels and ranches, return runs under concrete slabs corrode and collapse. The system then draws air from the crawlspace or basement, which is why some Hempstead homes smell musty the moment the fan starts.
- Asbestos-containing paper tape on original registers. Homes from the 1950s often have this tape sealing register boots to the floor. Standard agitation tools can disturb the fibers, so we identify it during inspection and follow safe-handling procedures rather than grinding through it.
- Oil-based residue in supply ducts. Decades of oil-fired forced-air heating leave a sticky film that attracts and holds dust. A brush alone won’t remove it. Our HEPA capture system with mechanical agitation does.
- Mold and mildew in poorly insulated ductwork. Hempstead’s humid summers push moisture into duct runs that run through unconditioned spaces. When that moisture meets dust and warm air, mold follows. We inspect for it, show you on camera, and clean with HEPA capture.

FAQs About Air Duct Cleaning in Hempstead
Because the original sheet-metal ducts were installed when these homes were built, and 60 to 80 years of settling, basement moisture, and retrofit work have taken their toll. Compact Hempstead lot sizes meant furnaces and duct runs went into tight spaces, where any foundation movement kinks or separates runs. Cleaning a system with a disconnected run is pointless until the run is repaired, because the vacuum can’t build proper negative pressure. Call (516) 559-4917 and we’ll inspect first.
We identify it during the video inspection and we do not disturb it with agitation tools. The fibers in that tape are hazardous when airborne, so we work around it using methods that don’t abrade the material. If the register boot needs work, we follow safe-handling procedures and coordinate accordingly. This is exactly the kind of thing a $99 coupon cleaning won’t catch. We catch it because we look first.
Yes. Our equipment is selected for tight Long Island basements and narrow side yards. We use compact negative-air units and low-profile agitation heads that fit through standard basement stairwells and around furnaces installed in tight corners. If we can reach the furnace, we can clean the system. We’ll tell you upfront if access is going to be a problem, and the written price accounts for it.
Repairing a crushed return run in Hempstead typically costs $180 to $400 per run, depending on how much of the run is damaged and whether we can access it from the basement or need to open a small section of ceiling. That includes the sheet-metal splice, proper support hangers, and mastic sealing on every accessible seam. We include this repair in the written quote before cleaning begins. Call (516) 559-4917 for a breakdown specific to your house.
Yes. Hempstead’s humid summers push moisture into duct runs that pass through unconditioned basements and crawlspaces, which creates conditions for mold and mildew on accumulated dust. Homes with window AC units and no central dehumidification are especially prone. We recommend a video inspection every three to five years for older Hempstead homes, and cleaning when the inspection shows visible buildup or moisture damage. A quick call to (516) 559-4917 gets you scheduled.
