Frequently Asked Questions

A proper cleaning covers the whole system: supply ducts, return ducts, the blower compartment, and the air handler cabinet. We connect a negative-pressure vacuum to the main trunk line to pull loosened debris out rather than blowing it into the living space. Then we run agitation tools through each branch line to knock dust and debris off the duct walls. The job ends with a visual check of the main runs and a before-and-after photo of your own ducts. In New York we also account for the building: window access, elevator service for equipment, and co-op work rules if your building has them.

Most apartments in Manhattan, Brooklyn, or Queens take between two and four hours. A standard two-bedroom on the Upper West Side with one air handler and eight to ten vents is usually a two-and-a-half-hour job. Larger homes in neighborhoods like Sunset Park or Red Hook with multiple systems and long trunk runs can take four to five hours. We'll give you a time estimate with your written quote, and we show up in the window we gave you. If access is slow, like a fifth-floor walk-up or a freight elevator reservation, that's built into the quote.

No, you can stay. The negative-pressure equipment contains the debris as it's pulled out, so we're not filling the living room with dust. You'll hear the vacuum running and feel airflow through the vents, and for the two to four hours we're working you'll be sharing the space with the equipment and the crew. Some New Yorkers go about their day; others step out to grab coffee while the heavy work happens. If you have a pet, we'll ask that they're kept in a room we're not actively working in so no one trips over a hose.

Clear a path to the air handler and the main return grill, which is usually in a hallway ceiling or a wall near the unit. Move anything fragile off window ledges, since the vacuum hose and agitation lines run through the apartment and vibration travels. In New York apartments, that often means clearing the entry hall and the closet that holds the mechanicals. If your building requires a certificate of insurance or a work permit, we'll handle that paperwork with management. Other than that, you don't need to do anything: we bring drop cloths, corner guards, and all equipment.

Resting dust comes mostly from the living space: the clothes you wear, the couch, the dog. But a percentage gets pulled into the return air, sits in the ductwork, and blows back out when the system runs. For apartments in neighborhoods like Greenpoint or the Financial District with new construction dust, older buildings with decades of tenant turnover, or homes with shedding pets, that recirculated portion is real. Cleaning the ducts removes it from the system. Most customers tell us surfaces stay cleaner for a few weeks longer between dustings. It's a difference, not a dust-proof guarantee.

Yes, and this is one of the most common calls we get in neighborhoods like Williamsburg and East New York where gut renovations happen constantly. Drywall dust, floor-sanding dust, and debris from demolition get pulled into the return ducts during construction and then blow back out once the system starts cycling normally. New Yorkers moving into a freshly renovated place often find a fine white film on every surface for the first month, and it's coming through the vents. We clean the system after the contractors are done so the new space starts with what's actually in the ducts gone.

We use truck-mounted and portable negative-air machines paired with powered agitation tools from brands like Rotobrush and Abatement Technologies. The vacuum does the capture work; the agitation tools knock the debris loose so the vacuum can pull it out. In New York's tighter buildings, the smaller footprint of portable units matters, because the machine has to ride the freight elevator or sit in a sidewalk entry. The tool doesn't clean the ducts on its own, the operator does. Our crew is trained on the equipment and the building access realities of New York City.

We don't sell filters as an upsell, but we do check the filter during the cleaning and tell you what condition it's in. If it's clogged, we'll recommend a replacement at the MERV rating your system was designed for; you can buy it from us or anywhere else. For New York apartments, a good pleated filter changed every two to three months does more for year-round dust than any add-on. Aprilaire and other quality brands make filters that fit most residential air handlers, and your building's super or your HVAC tech can confirm the correct size. We don't push a product line; we tell you what the system needs.

We judge by the result, not the name on the machine. Rotobrush and Abatement Technologies make solid agitation and vacuum equipment, and both are common in professional duct cleaning. The far bigger variable is the operator, not the tool. A skilled tech with a basic vacuum and agitation set will do better work than a careless one with the fanciest rig. What matters is the process: negative air containment, agitation on every branch line, and a visual check afterward. When you're comparing New York duct cleaners, ask about their process, not which machine they own. That's the question that separates the honest operators.

Every professional working under the Kestrel name in New York is required to hold the license and insurance their state and local jurisdiction requires. We carry insurance and can provide a certificate of insurance to any building or co-op board that asks for one, which is a standard part of working in New York City's managed buildings. Dale Whitmore runs this branch to that standard. If a building requires a work authorization or insurance rider specific to the property, bring it to us before scheduling and we'll work with management to clear it.

Air duct cleaning in New York doesn't require the same trade license as electrical or plumbing work, because it's a maintenance service, not a building-systems installation. But the unlicensed, uninsured route is how homeowners get hurt or have equipment damaged with no recourse. Ask any company you're considering for proof of insurance and a written process. If they hesitate on either, hang up. We're happy to provide a certificate of insurance to your building board or property manager, which most New York co-ops and condos require before any vendor steps into the mechanical room.

Look for four things: a written price before work starts, a real arrival window, insurance you can verify, and a guarantee in writing. Those four promises are the core of The Kingswell Guarantee, and every Kingswell company works to them. Beyond that, ask questions: How do you clean, not just vacuum, the duct walls? Will I see my own before-and-after photos? Does the price change if you find something unexpected? A company that answers those directly is a company that has actually done the job before. New York has no shortage of duct cleaners; the goal is to find one that doesn't waste your afternoon and then surprise you with the invoice.

We don't run an emergency call line, because air duct cleaning is a scheduled service, not a burst-pipe situation. What we do is maintain a regular schedule that runs Monday through Friday from 7:00 AM to 7:00 PM, and Sundays from 7:00 AM to 7:00 PM, and we show up in the window we gave you. If you have a specific need, like a renovation deadline or a tenant move-in date, tell us when you call (585) 517-2324 and we'll find a slot that fits. If there's a true HVAC emergency, like no heat in January, that's a job for an HVAC contractor, not a duct cleaning crew.

We work on a scheduled basis, not a drop-everything dispatch. Depending on the season, we can usually get a crew to your building in Manhattan, Brooklyn, or nearby within a few days to two weeks. Fall and spring fill up faster, because New Yorkers remember the ducts when the heat kicks on and when the allergy season starts. Call (585) 517-2324 and we'll tell you honestly when we can get there. No countdowns, no pressure, just a real slot in the schedule. We're closed Saturdays, but we clean on Sundays, which fits a lot of weekend doormen schedules.

Yes, and in New York this is standard procedure, not a special request. Most buildings in the Upper East Side, Murray Hill, and the Financial District require a certificate of insurance on file, approved work hours, and sometimes a notice to the super or the management office. We'll provide the COI, follow the window rules, and coordinate with the super for mechanical room access. If your building requires an elevator reservation or a security escort, we'll confirm all that before the scheduled day. New York buildings make the rules, and we've worked under most of them.

You can vacuum the register openings and change the filter, and both help. What you can't do from inside the apartment is reach the inside of the duct runs, and that's where the buildup actually is. The trunk lines in a New York apartment often run through walls, ceilings, and behind the kitchen; without negative-air equipment and agitation tools, you're only cleaning the first few inches of the register. We've seen homeowners try a shop vac and a dryer brush and give up after an hour. The professional job reaches what you can't see and captures the debris instead of pushing it further down the run.

No, cleaning your ducts poorly doesn't void an HVAC warranty by itself. But damage from DIY attempts, like puncturing a flex duct with a bent coat hanger or tearing a boot connection with a drill brush, is not covered by any equipment warranty. In a New York apartment, that damage often means access through walls or ceilings to fix, which is a much bigger job than the cleaning would have been. Our equipment is designed for this work, and our crew knows where the fragile points are in both new high-rise systems and old prewar metal duct runs.

Keep yourself away from anything connected to the gas furnace, the electrical panel, or the air handler cabinet if you're not trained for it. The blower compartment has moving parts, exposed wiring leads, and is often tight and awkward to reach; that's how people get hurt. We use brushes and vacuums made for the job, and our crew knows how to work around the electrical and gas connections safely. For the registers and the surfaces around them, a standard vacuum with a HEPA filter bag is all you need between professional cleanings. The inside of the duct runs is the line where DIY stops making sense.

Yes. Every Kingswell company works to the Kingswell Guarantee: a written price before any work starts, a real arrival window, a clean job site, and a written guarantee on the work. If a repair fails inside the guarantee period, we come back and fix it at no charge. For duct cleaning specifically, that means if the system shows immediate, visible re-contamination that's traced to our work, we return and re-clean the affected runs. The guarantee is in writing, not a verbal "trust us." That's The Kingswell Way: put the guarantee in writing.

The written guarantee covers the work we performed on the day of the cleaning. If the ducts we cleaned show a visible problem that stems from our process, not from normal household dust accumulation after the fact, we come back and address it at no charge during the guarantee period. The guarantee is printed on your invoice and your receipt. It's not a lifetime warranty against future dust, because no honest company can promise that; it's a standing behind the work we did, in writing. If you have questions about what's covered, ask before you book, and we'll explain it in plain language.

Call us at (585) 517-2324 and tell us what's wrong. The Kingswell Guarantee includes a come-back provision for the guarantee period: if the work wasn't done right, we return and fix it at no charge. We'd rather come back and make it right than have a New York homeowner wonder if every duct cleaner is the same. Dale Whitmore runs this branch with that simple rule: leave the place cleaner than we found it, and stand behind the work in writing if it falls short. Most issues are resolved with one follow-up visit.
