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.

AfterAir Duct Cleaning in Smithtown, NY
Dryer vent cleaning in Smithtown is the service we get called for most often, usually after a homeowner notices the dryer taking two cycles to finish a load. Most of those calls come from ranch, Cape Cod, and split-level homes built between the late 1940s and early 1970s, where original sheet-metal ductwork carries decades of accumulated lint, dust, and in many cases oil-heat soot. The Long Island humidity makes it worse: moisture causes lint to clump and bind inside vents rather than blow through. If you’re in Smithtown and your dryer isn’t drying, call (806) 606-6902 and we’ll give you a written price before any panel comes off.
Why Smithtown Homes Are Different
Smithtown’s housing stock was built in a specific window of postwar expansion, and the ductwork inside those homes carries the marks of that era. Ranches, split-levels, and Cape Cods constructed from the late 1940s through the early 1970s were framed around short, straight duct runs that are easy to access but rarely sealed well. Joints were left open by design in some cases because oil-fired forced-air systems needed make-up air. What that means for a homeowner today is a network of ducts that has been pulling attic and crawlspace air into the living space for 50 to 70 years, and the dust, soot, and humidity that comes with it.
Suffolk County has a significantly higher concentration of oil-fired heating than the national average, and Smithtown is no exception. Oil combustion produces a fine, dark particulate that settles into ductwork in a way natural-gas systems simply don’t match. That soot bonds with normal household dust and the humidity Long Island carries year-round, forming a stubborn film inside the ducts. Spring and fall temperature swings create condensation along unsealed joints in older runs, and moisture against 60-year-old fiberglass duct liner is a reliable recipe for mold. Many Smithtown homes have never had a professional duct cleaning in their lifespan. The ductwork was run, the walls were closed, and nobody has looked inside since.
There is one more thing we flag on Smithtown jobs that out-of-area crews routinely miss: homes built during the 1950s and 1960s construction wave sometimes contain asbestos-containing duct wrap or plenum board. A pre-inspection step is required before any mechanical agitation. Our technicians know to identify those materials and stop the job until they are properly handled, instead of blowing asbestos fibers through the house. That liability alone is a reason to use a crew that actually works in Smithtown, not one dispatched in from somewhere else.
Our Main Smithtown Services
Smithtown homeowners most often call us about two things: full air duct cleaning and complete HVAC system cleaning. Both address the oil soot, humidity-driven mold, and decades of accumulated debris common to mid-century Long Island homes, but they are different jobs with different scopes.
Air Duct Cleaning in Smithtown
Air Duct Cleaning in Smithtown is a full-system job: every supply and return run, the plenum, the blower compartment, and each register. For Smithtown homes with original 1950s-to-1970s ductwork, this is the service that removes oil soot deposits, construction debris from the original build, and the accumulated pet hair and skin cells that have been circulating for decades. A Rotobrush or Nikro negative-pressure system pulls debris out of the runs instead of blowing it into the rooms. Each run is photographed before and after, and you see the record when we’re done.
HVAC Cleaning in Smithtown
HVAC Cleaning in Smithtown goes beyond the ductwork to the equipment that moves air through the system. It covers the evaporator coil, blower wheel, blower motor housing, heat exchanger surfaces, and condensate pan. In Smithtown’s oil-heated homes, the blower wheel often carries a paste of soot and moisture that reduces airflow and strains the motor. This is a cleaning that can be done on the same visit as air duct cleaning, and it is one of the things we recommend when a home has never had the equipment opened up.

BeforeAfterDryer Vent Cleaning in Smithtown
Dryer vent cleaning in Smithtown is about lint, humidity, and a dryer that works harder than it should. Smithtown’s housing stock from the late 1940s through the early 1970s often has short exterior-wall vent runs, but the real problem is accumulated lint binding with moisture from Long Island’s maritime air into a hardened mass that restricts airflow at the elbows. Add oil-heat soot into the mix when the dryer pulls air from a basement shared with the furnace, and you have vents that clog faster than in newer gas-heated suburbs. Every Dryer Vent Cleaning job we complete ends with a written price up front and a photo record of the inside of the vent before and after we clean it.
Dryer Vent Inspection
Signs you need it
The dryer runs a full cycle and the clothes are still damp, the exterior vent flap doesn’t open when the dryer is on, or the laundry room heats up while the dryer runs.
What it costs in Smithtown
A dryer vent inspection in Smithtown typically runs $85 to $155, and the cost is waived when you book a cleaning on the same visit.
How we do it
We run a camera through the full vent run, photograph every elbow and termination point, and show you what we found before any cleaning starts.
Vent Cleaning
Signs you need it
The dryer takes two or three cycles to dry a load, there is a burning smell while the dryer runs, or the exterior vent is covered in lint buildup.
What it costs in Smithtown
Expect to pay $125 to $260 in Smithtown for a standard dryer vent cleaning, depending on run length and access.
How we do it
We use a rotary brush and negative-pressure collection system to break up hardened lint, pull it out of the run, and then photograph the vent interior from both ends.
Lint Removal
Signs you need it
Visible lint is packed around the dryer’s lint trap housing, or the trap itself no longer catches lint because the vent is backing up.
What it costs in Smithtown
Lint removal beyond a standard vent cleaning runs $95 to $185 in Smithtown when it involves removing the dryer, accessing the transition duct behind it, or clearing a severely packed run.
How we do it
We pull the dryer, remove the transition duct, clear the entire vent path by hand and machine, and document the before-and-after condition in photos.
What Dryer Vent Cleaning Costs in Smithtown
| Item | Typical range in Smithtown |
|---|---|
| Dryer vent inspection | $85 - $155 |
| Dryer vent cleaning | $125 - $260 |
| Lint removal (beyond standard cleaning) | $95 - $185 |
Prices in Smithtown run at the higher end of these ranges when the vent is on an upper floor with a roof termination, when the run is long with multiple elbows, or when the vent has never been cleaned since the home was built.
How often should a dryer vent actually be cleaned in Smithtown?
Every one to two years for most Smithtown homes, more often if the dryer runs daily with a large family. The humidity on Long Island causes lint to bind sooner than in dry-climate homes. Call (806) 606-6902 and we’ll inspect the vent and tell you what it needs.
Why do some dryer vent cleaning quotes in Smithtown come in so low?
Low quotes usually cover only the first few feet of vent from the dryer, not the full run to the exterior, or they skip the photo documentation entirely. A real cleaning covers the entire run and shows you proof. CleanRun gives you a written price for the whole vent before we start.
Duct Repair & Sealing in Smithtown
Duct repair and sealing in Smithtown is about closing the leaks in systems that were built 50 to 70 years ago and never touched since. Many of Smithtown’s original sheet-metal duct runs have open joints, missing screws, and gaps where the metal was fitted loosely during the original construction, leaking conditioned air into attics and crawlspaces. The humid Long Island air moves through those gaps year-round, pulling damp air into the system in summer and pushing heated air out in winter. A Duct Repair & Sealing job in a Smithtown home means finding every leak, sealing it properly, and showing you the before-and-after photos so you can see which runs were leaking.
Duct Sealing
Signs you need it
Some rooms in the house are always colder than others, your oil bill keeps rising without a change in usage, or you can see dust streaks on the drywall near registers.
What it costs in Smithtown
Duct sealing in Smithtown typically costs $450 to $1,200 depending on the number of accessible runs and how much of the system is reachable from the basement or attic.
How we do it
We locate leaks by hand and with a pressure test, seal each joint with mastic or foil tape rated for ductwork, and photograph every repair.
Metal Duct Repair
Signs you need it
You can see crushed, disconnected, or rusted-through metal sections in the basement or crawlspace, or air is blowing into the crawlspace instead of the rooms.
What it costs in Smithtown
Metal duct repair in Smithtown ranges from $300 to $850 depending on access and how many sections need to be patched or replaced.
How we do it
We remove the damaged section, fabricate or order a matching replacement, secure it with screws and sealant, and document the repair with photos.
Duct Insulation
Signs you need it
The ducts in an unconditioned attic or crawlspace sweat in the summer, or the air from the registers feels warm in the summer and cold in the winter despite the system running.
What it costs in Smithtown
Insulating accessible ductwork in Smithtown runs $380 to $1,000 depending on the total linear footage and whether the ducts are in an attic, crawlspace, or basement.
How we do it
We wrap each accessible run in fiberglass insulation or install insulated duct board where appropriate, sealing every seam against moisture entry.
What Duct Repair & Sealing Costs in Smithtown
| Item | Typical range in Smithtown |
|---|---|
| Duct sealing | $450 - $1,200 |
| Metal duct repair | $300 - $850 |
| Duct insulation | $380 - $1,000 |
Costs climb in Smithtown when the ductwork is in a tight crawlspace, when original asbestos-containing wrap needs to be identified and handled before work starts, or when long runs require repair in more than two or three locations.
Can duct sealing actually lower heating costs in a Smithtown home?
Yes. Sealing leaks in a mid-century Smithtown system can reduce the amount of conditioned air lost to the attic and crawlspace by 20 to 30 percent in some homes. Call (806) 606-6902 and we’ll give you a written price for your system specifically.
How do I know the duct repair was actually done correctly in Smithtown?
Our technicians photograph every sealed joint and repaired section before and after, and those photos are delivered to you as part of the job record. Haven Standard Clause 1 means you get a written price before work and documented proof after. If it isn’t right, the 365-Day Done Right Promise covers fixing it.
Air Quality & Sanitizing in Smithtown
Air quality and sanitizing in Smithtown is about treating what grows inside aging ductwork when Long Island humidity meets decades of accumulated debris. The fiberglass duct liner common in homes built during Smithtown’s 1950s through 1970s construction wave absorbs moisture and provides a substrate for mold and bacteria that then circulate through the house every time the blower cycles. In spring and fall especially, condensation along unsealed joints wets that liner and dormant spores activate. An Air Quality & Sanitizing service applies a registered antimicrobial treatment to the interior surfaces of the duct system, and then we document the work with the same photo record we use on every job.
Mold Treatment
Signs you need it
Musty smell comes through the registers when the heat or AC runs, visible mold is present on register covers or inside the ductwork, or household members have unexplained allergy symptoms that improve away from home.
What it costs in Smithtown
Mold treatment for ductwork in Smithtown typically costs $450 to $1,100 depending on the size of the system and the extent of the affected area.
How we do it
We clean the affected surfaces mechanically, apply an EPA-registered antimicrobial to the interior of the duct system, and photograph the affected areas before and after treatment.
Bacteria Sanitizing
Signs you need it
A persistent stale or sour odor comes from the vents even after cleaning, or someone in the household has been ill and the system needs a whole-house microbial reset.
What it costs in Smithtown
Bacteria sanitizing in Smithtown runs $350 to $800, with the final price depending on system size and whether it is paired with a full duct cleaning.
How we do it
We apply a hospital-grade sanitizing agent through the running system so every duct surface, the plenum, and the blower compartment receive full contact.
UV Light Installation
Signs you need it
Mold or bacteria keeps returning after cleaning, the evaporator coil shows visible growth, or you want continuous treatment of the air stream as the system runs.
What it costs in Smithtown
UV light installation in Smithtown costs $850 to $1,800 installed, depending on system size and whether one or two lamps are needed.
How we do it
We mount the UV lamp in the supply-side plenum or at the coil using branded units, wire it to operate with the blower, and show you the completed install with photos.
What Air Quality & Sanitizing Costs in Smithtown
| Item | Typical range in Smithtown |
|---|---|
| Mold treatment | $450 - $1,100 |
| Bacteria sanitizing | $350 - $800 |
| UV light installation | $850 - $1,800 |
In Smithtown specifically, the price goes up when the home has never had the duct system opened, when multiple runs show mold growth, or when the asbestos check reveals materials that need to be handled before treatment can proceed.
Is air duct sanitizing safe for homes with kids and pets in Smithtown?
Yes, we use EPA-registered antimicrobials applied at the concentrations specified for occupied spaces. We’ll tell you what product we’re using and what re-entry guidance applies before we start. Call (806) 606-6902 for specifics on your system.
How long does air quality treatment last in Smithtown’s humid climate?
Mold and bacteria treatments typically last 12 to 24 months before re-treatment is needed, but Long Island’s humidity means the underlying moisture source must also be addressed. If the ductwork stays damp, the growth returns. We’ll check for leaks and condensation issues during the job.

FAQs About Air Duct Cleaning in Smithtown
No permit is required for duct cleaning, dryer vent cleaning, or duct sealing in Smithtown. Mechanical work involving new furnace installation or major HVAC replacement falls under a different requirement, but the services we perform on existing ductwork do not require a town permit. Call (806) 606-6902 if you’re unsure about your specific situation.
Most Smithtown appointments happen within three to five business days of the initial call. We schedule a specific date and time window with you, and the technician arrives uniformed and identified by name before entering. No vague “sometime between 8 and 8” windows.
Yes, that’s the majority of what we see in Smithtown. Oil-fired forced-air systems produce soot that bonds with duct surfaces differently than gas, and the original sheet-metal runs in 1950s through 1970s homes require a more careful cleaning and inspection process. We’ll walk you through what we find and show you the photos to prove it.
