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.
Fast, Reliable HVAC Cleaning Across Sunset Park
HVAC cleaning in Sunset Park usually costs between $425 and $680 for a full system clean in a typical rowhouse retrofit, and the single most common thing our crews find is diesel soot caked into the supply plenum and coil fins. That’s not a generic industry claim. It’s what the camera shows on at least seven of every ten jobs we do between 2nd and 5th Avenues, directly beneath the elevated Gowanus Expressway. The job takes most of a day, and the written price you get before work starts is the price on the final invoice. That’s Haven Standard Clause 1, and it’s been the rule on every job since 2013.
Call (806) 606-6902 and a live person answers. We’ll schedule a crew that knows Sunset Park’s retrofitted duct runs, not a generic appointment.
Why CleanRun Air Duct Cleaning Is Sunset Park’s Preferred HVAC Cleaning Company
Sunset Park’s housing stock is almost entirely pre-war brick rowhouses, most built between 1895 and 1930 and originally heated by steam radiators. No ductwork. Every forced-air system in these buildings is a retrofit, squeezed through load-bearing masonry, joist bays, and shared party-wall chases. Standard 8-inch duct whips do not fit into a 3.5-inch joist-bay cavity. A technician who does not know that will leave half the run untouched and tell you the job is done. We know the difference because we have photographed it hundreds of times in this neighborhood.
Every CleanRun crew working in Sunset Park operates under the H.A.V.E.N. Standard. Clause 3 means background-checked, uniformed technicians identified by name before they arrive. Clause 1 means a written price before a single panel comes off. And on every job, we hand over a Documented Photo Record of every duct run, before and after, as a standard deliverable. You see what was inside. You see what we removed. You do not have to take anyone’s word for it. Tomas Reyes, our owner, has kept that rule on every job we have done since 2013.
Our HVAC Cleaning Services in Sunset Park

Evaporator Coil Cleaning in Sunset Park
A dirty evaporator coil is the most common efficiency killer in Sunset Park rowhouses. Harbor moisture keeps the coil damp even when the system is off, and that damp surface grabs diesel particulate from rooftop intakes beneath the Gowanus. In a typical 1920s subdivided rowhouse on 4th Avenue, we routinely pull coils with a visible black film that cuts heat transfer enough to add real dollars to summer electric bills. We clean the coil fins with a negative-pressure extraction system sized for the tight mechanical closets these retrofits have, and we photograph the coil before and after. No fogging sanitizer. The photo shows the work.

Air Handler Cleaning in Sunset Park
Air handlers in Sunset Park retrofits sit in cramped closets, dropped soffits, or basement corners, and they rarely get the clearance the manufacturer assumes. Moisture from the harbor works its way into the cabinet, rust forms on the blower wheel, and the condensate pan becomes a breeding surface for biofilm. We open the handler, remove the blower assembly, clean the wheel and housing, and treat the pan. If the pan is rusting through, we tell you in the written scope, because a “clean” that skips pan treatment buys you maybe six months before the next failure. On 4th Avenue between 2nd and 5th Streets, our crew opened a coil on a retrofitted Goodman air handler in a subdivided 1920s rowhouse and found black carbon caked inside the supply plenum. Diesel soot pulled from rooftop intakes directly beneath the expressway. We ran Rotobrush agitation tools with a brush head sized for the narrow joist-bay runs, pulled negative pressure through a HEPA-filtered vacuum, and left the coil fins clean without spraying anything into the system.

Condenser Cleaning in Sunset Park
Condenser coils on Sunset Park rooftops and rear yards collect a mix of harbor salt, diesel soot, and the usual urban grime. Salt air accelerates corrosion, so a coil that is merely dirty in Queens is actively degrading on a rowhouse rooftop near Upper New York Bay. We clean the condenser coil with equipment that flushes the fins without bending them, check the refrigerant lines for visible wear, and document the condition in the photo record. If the coil is far enough gone that cleaning will not restore function, you will know before you pay for it, because the written price is based on what we find, not on a coupon.

Heat Exchanger Cleaning in Sunset Park
Heat exchangers in Sunset Park’s retrofitted gas furnaces face an extra load because many of these systems were installed decades after the building was built, often with undersized returns and improvised combustion air. A fouled heat exchanger is both a comfort problem and a carbon monoxide risk when airflow is restricted. Our cleaning removes the debris that restricts heat transfer, and if the inspection shows a crack or corrosion that makes the exchanger unsafe, we stop and tell you. We do not clean around a safety issue and leave it for next year.

AfterTrusted Brands We Service in Sunset Park
Most Sunset Park retrofits run on Goodman, Carrier, Rheem, or Trane equipment, with Honeywell controls and the occasional Aprilaire media cabinet. Our crews service all of them. We carry the brush heads, coil combs, and access panel gaskets specific to these brands, so a rowhouse air handler in a tight closet does not wait a week for a part. The equipment we clean with includes Rotobrush agitation systems, Nikro negative-air machines, and Abatement Technologies HEPA vacs. Those are professional-grade tools you can look up before you agree to a price. We name them because you should be able to verify what will be used in your home.

Common HVAC Cleaning Problems We See in Sunset Park Homes

- Diesel soot loading from the Gowanus Expressway. The elevated I-278 runs above 3rd Avenue through the heart of Sunset Park. Rooftop intakes on the upper floors of rowhouses pull truck exhaust directly into the return side, and the soot settles in the supply plenum and on coil surfaces. The debris we pull on blocks between 2nd and 5th Avenues consistently has heavy black carbon loading, a signature pattern tied to the expressway’s truck traffic.
- Harbor-driven mold inside retrofit duct runs. Sunset Park sits on a ridge above Upper New York Bay. Moisture infiltrates the older brick building envelope, and poorly sealed retrofit ducts hold that dampness. Bio-contamination is a more common finding here than in inland Brooklyn neighborhoods like Flatbush, because the humidity inside the building is higher even in winter.
- Undersized duct runs that resist standard equipment. The joist bays and party-wall chases in these rowhouses were never meant for forced air. Standard 8-inch duct whips cannot turn through a 3.5-inch joist-bay cavity. A crew that arrives with only standard gear will miss significant sections of the run, and the customer will never know because no one photographs the inside.
- Fire-separation breaches between units. When retrofit ducts run through shared party walls, cleaning crews sometimes cut access holes into the chase and fail to seal them afterward. That breaks the fire separation between units and creates a cross-contamination pathway from one apartment to the next. We seal every access point we open, with fire-rated materials where the chase penetrates a party wall, and we photograph the sealed opening in the job record.
Pricing for HVAC Cleaning in Sunset Park, NY
We quote whole-system prices, not per-vent figures, and the number is in writing before any work starts. For a typical Sunset Park rowhouse or garden apartment unit with a single retrofitted air handler, a full HVAC clean, including evaporator coil cleaning, air handler cleaning, blower cleaning, and condenser cleaning, runs between $425 and $680. A two- to three-story rowhouse with two systems runs $690 to $940. Condensate pan replacement, if the pan is rusted through, adds $60 to $145 depending on the pan. Heat exchanger cleaning on a gas furnace runs $95 to $165 as part of a full clean. If a competitor quotes you lower, bring the written estimate and we will put our own number next to it in writing. That is our Free Second Opinion, and it costs nothing.

FAQs - HVAC Cleaning in Sunset Park

Sunset Park sits on a ridge directly above Upper New York Bay, and the harbor moisture penetrates the older, minimally insulated brick building envelope. That keeps indoor humidity elevated year-round, and the dampness collects inside the poorly sealed retrofit duct runs common in these pre-war rowhouses. Flatbush, by comparison, has more frame construction and sits further inland, so the building envelope dries out faster. The result is faster mold and mildew colonization in Sunset Park ductwork, especially in the supply plenum and around the evaporator coil. If you are seeing black spots on your registers or a musty smell when the system kicks on, call (806) 606-6902 and we will put a camera inside the run before we clean it.
No. A fogging sanitizer can kill surface spores temporarily, but it cannot remove the biofilm and debris that feed the mold. The mold in a rowhouse air handler lives on the damp surfaces of the coil and pan, and it grows back as soon as the sanitizer dissipates, usually within weeks. The only effective approach is physical removal: cleaning the coil fins, clearing the blower wheel, treating the pan with a proper antimicrobial meant for HVAC surfaces, and addressing the moisture source. Any company that charges extra for a “fogging treatment” before doing the physical clean is selling you an upsell that will not hold. We do not fog. We remove. Ask for the photo record.
Yes, and you can verify it with your own eyes. The elevated I-278 runs at or above rooftop level along 3rd Avenue, and truck exhaust plumes flow directly into rooftop intakes and upper-floor wall vents on the rowhouses beneath it. The soot settles inside the return duct, the supply plenum, and the evaporator coil. When our crew opens a unit on 4th Avenue between 2nd and 5th Streets, the first thing the camera shows is usually heavy black carbon caked inside the plenum. The Documented Photo Record you receive after the job shows it before and after, so you can see what was actually in there. That is information a generic duct cleaning page will not tell you, and it is the reason you should use HVAC Cleaning that understands Sunset Park’s air quality problem.
Negative pressure means the cleaning system is pulling air out of the duct run with more force than it is pushing in, so the debris released by the agitation tools travels into the vacuum and not into your living space. We connect a HEPA-filtered vacuum machine, such as a Nikro or Abatement Technologies unit, to the system and run the agitation tools inside the ducts while the vacuum keeps the entire run under negative pressure. For the narrow joist-bay and party-wall chase runs common in Sunset Park retrofits, the negative-pressure setup has to be sized to the restricted airflow. Standard machines on tight runs will not pull enough volume to stay negative, which means dust escapes into the room during cleaning. We size the vacuum to the run. Call (806) 606-6902 and we will explain the setup in writing before we start.
No. If your building still heats with the original steam radiators and has no forced-air system, there are no air ducts to clean. What you may need is radiator maintenance, which we do not perform. If someone tells you that you need duct cleaning in a steam-heated rowhouse, they are selling you a service that does not apply to your building. The exception is if you have a window unit or a separate ducted AC system added later. If that is the case, the coil and the short duct run can absolutely collect soot and harbor moisture. We will tell you in writing whether a clean is warranted, and if it is not, we will tell you that too.
