Fast, Reliable Air Duct Cleaning Across North Merrick
Air duct cleaning in North Merrick typically costs between $350 and $650 for a full system on an average 1,800-square-foot home, with smaller split-levels and Cape Cods running closer to $300 – $450. Most jobs take four to six hours, and we schedule within a few business days. If your home still has its original mid-century ductwork or a retrofitted central air system, the price will lean toward the higher end because those runs need real access work, not just a quick pass with a vacuum. That’s the work we do every week in North Merrick, and it’s exactly what the homes here need. Call Hollis Air Duct Hempstead at (516) 559-4917 and we’ll give you a written price before anything starts.

Why Hollis Air Duct Hempstead Is North Merrick’s Preferred Air Duct Cleaning Company
We’re not new to this. Hollis Air Duct Hempstead has been in business since 2004 as part of the Garrison Partners family, and our team has cleaned a lot of the Cape Cods and split-levels between Jerusalem Avenue and Camp Avenue. The ductwork in these homes is not like the wide-open runs you find in newer construction. It’s tight, it’s retrofitted, and it’s almost always hiding something the homeowner hasn’t seen since the last oil delivery guy left for good.
Our technicians are background-checked, uniformed, and trained on the equipment we actually bring into your home: Rotobrush rotary brush systems and Nikro negative-air machines, not hardware-store gear. We answer our phones with a live person, 24 hours a day. No callback queues, no voicemail maze. One call to (516) 559-4917 gets you a straight answer and a written price.
Every job is covered by the 365-Day Done Right Promise. That means if something is not right within a full year, we come back at no charge. That includes a free second visit. Not negotiated. Written down.
Styles & brands we work with




Commercial Air Duct Cleaning in North Merrick
Commercial Air Duct Cleaning in North Merrick runs $800 – $2,500 depending on square footage, number of rooftop units, and how much access the ducting actually gives us. Offices, medical suites, and retail spaces along Jerusalem Avenue and Camp Avenue all have one thing in common: the ducts have been holding years of dust, and the filters have been loading up faster every season. That’s not a mystery in North Merrick. It’s the salt air and the spring pollen doing what they do.
Office and Retail Spaces
These jobs usually mean suspended-ceiling return plenums and decades-old rooftop units. We clean the full supply and return network with negative-air containment so we’re not blowing dust into the space while we work. The written price covers the whole system, not a per-vent add-on that appears after the crew gets started.
Restaurant and Food Service Ducts
Grease-laden air in kitchen exhaust and make-up air units is a fire and health issue. We clean the run, document it before and after with camera inspection, and leave you with the proof. That’s the standard, not an upsell.
Air Duct Cleaning Services in North Merrick
Air Duct Cleaning Services in North Merrick start at $350 for a full residential system in a smaller Cape Cod, and climb to $650 – $850 when the home is a split-level with multiple returns, old supply runs, and a retrofitted central air system. The first thing we do is a camera inspection of the main supply trunk, the return side, and any abandoned plenums we find. That inspection changes what the job actually costs, because it shows us what’s really back there.
Full System Cleaning
We clean the supply side, the return side, the blower motor, the coil, and the registers. In North Merrick, that almost always means getting into a shallow crawlspace or a low-clearance basement to reach runs that were never designed to be cleaned. We do the access, and we leave the site clean.

Video Inspection and Verification
Before we leave, we run the camera again and show you what changed. If there’s a disconnected return, a ghost plenum pulling damp air, or a bypass that was never sealed, you’ll see it on the screen. And we’ll fix it. That’s what separates our Air Duct Cleaning team from a couple of guys with a shop vac and a fogger.

Trusted Brands We Service in North Merrick
We service and clean ductwork connected to Honeywell filtration systems, Aprilaire media cabinets, Abatement Technologies negative-air setups, and just about every furnace and air handler from the 1960s forward. We carry common replacement filters and duct mastic on board, so when we find a leaky elbow or a failed seal during cleaning in a North Merrick basement, we can fix it right then instead of scheduling another visit. If your system uses a Guardsman filter cabinet, we can source replacements and explain the differences before you spend money on the wrong media.

AfterCommon Air Duct Cleaning Problems We See in North Merrick Homes
- Abandoned warm-air plenums from oil-to-gas conversions: Many original oil furnaces left behind plenums that were never removed. They sit open in crawlspaces and pull damp, salty air into the duct system every time the fan runs.
- Shallow basement and crawlspace supply runs packed with debris: The tight clearances under North Merrick Capes and split-levels make duct cleaning access difficult, so a lot of crews skip those runs entirely. They stay packed with construction debris and corroded duct liner.
- Rapid filter loading from oak and maple pollen: Each spring, pollen from the dense tree canopy around North Merrick streets clogs filters within weeks. If the return side is leaking or the filter rack is loose, that pollen bypasses the filter and coats the coil and blower.
- Mold and mildew from South Oyster Bay humidity: The damp coastal air doesn’t stay outside. It gets pulled into ducts, especially through unsealed crawlspace returns, and the result is a musty smell that returns every summer.
Pricing for Air Duct Cleaning in North Merrick, NY
A typical full-system residential cleaning in North Merrick runs $350 – $650. Homes with tight crawlspace access, multiple returns, or abandoned plenums that need sealing land in the $550 – $850 range. Commercial spaces start around $800 and go up with square footage and equipment count. The price we write down is the price you pay. We don’t do per-vent pricing, and we don’t hit you with a “mold treatment” number after the crew opens a register. A free camera inspection is part of every estimate. Call (516) 559-4917 and we’ll put it in writing.
We recently cleaned a split-level off Jerusalem Avenue with a 1990s central air retrofit where the return duct was shoehorned through a low-clearance crawlspace. Our camera inspection found the original oil-plenum bypass pulling damp, salty air from the crawlspace, coating the blower motor and registers with a fine gray biofilm. After source removal and sealing the ghost run, the static pressure dropped and the musty smell was gone within a day. That is the kind of fix you only find when you look for it. And in North Merrick, you have to look.

FAQs About Air Duct Cleaning in North Merrick
Because those plenums are still connected to your duct system. When North Merrick homes converted from oil to gas, the old warm-air plenums were often left in place and became bypasses that pull untreated crawlspace air into the supply side. A real cleaning has to identify and seal those ghost runs, or the mold and damp smell come right back within months.
Salt air holds more moisture, and that moisture settles inside ductwork in homes within a few miles of the water. In North Merrick, we see more biofilm on blower motors, more rust on register faces, and more mildew in return ducting than we do in Hempstead or Massapequa. The difference is real, and it’s why camera inspection matters here more than in dryer inland areas.
Fogging wets the surface. Source removal pulls the contaminated material out. If you have a moldy blower motor, a corroded duct liner, or a return duct packed with damp debris, fogging just turns that into wet moldy debris. We remove the source and seal the entry points, then you don’t need to fog anything.
Oak and maple pollen around North Merrick is thick from April through early June. If your return side is leaking, especially through a crawlspace, that pollen bypasses the filter entirely and lands on your coil and blower. A tight return and a clean coil make your filter do what it’s supposed to do instead of fighting a losing battle.
Yes. We work in the low-clearance basements and crawlspaces common under mid-century North Merrick Capes and split-levels. It takes more time, and it’s why we don’t quote a one-size-fits-all price. But the run gets cleaned, not skipped. Our camera shows you the before and after. Call (516) 559-4917 for an exact quote. Estimates are free.
