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 Brooklyn
HVAC cleaning in Brooklyn typically runs $395 – $680 for a full system in a standard apartment or brownstone, and the honest version of the job takes 2 – 4 hours with real equipment, not a shop vac waved at your registers. We’re Cardinal Air Duct Cleaning, part of the Relay Home Co. family founded in 2005, and we serve every corner of the borough, from Bay Ridge to Williamsburg to Flatbush. If your AC blows musty air or your radiators are coated in dust that puffs out every time the heat kicks on, call (737) 727-2314 and we’ll give you a written price before anyone touches a duct.
Why Cardinal Air Duct Cleaning Is Brooklyn’s Preferred HVAC Cleaning Company
Brooklyn homeowners deal with equipment that most suburban HVAC companies simply don’t understand. Pre-war buildings on Ocean Parkway, walk-up apartments in Greenpoint, postwar co-ops in Sheepshead Bay, each one has its own duct layout, access quirks, and building management rules. Our technicians know that a Crown Heights brownstone’s return chase might be unreachable without a camera, and that a Park Slope co-op board might require proof of insurance before we even park the van. That local knowledge changes how the job gets done.
Omar Haddad leads our team here, and the standard he set is simple: name the tech, hand over a written price before the work starts, and show the customer photos of their own ducts when it’s finished. That’s the Relay Standard, and it applies to every booking without exception. When a Brooklyn customer calls, they get a background-checked, uniformed technician, a live trackable arrival window on their phone, and a digital invoice payable by link when the job is done. No four-hour arrival windows. No price shift once the tech is inside.
We’re held to the 365-Day Done Right Promise: if the work isn’t right within 365 days, we come back and correct it at no charge. That’s the longest satisfaction window in duct cleaning, and it covers every job we do in Brooklyn, not select ones. A large part of why customers in this borough choose us is that promise, because they’ve been burned by one-visit companies that vanish the moment the invoice clears.
AC Cleaning in Brooklyn
AC Cleaning in Brooklyn means getting the cooling side of the system actually clean, not just blowing compressed air at the visible parts. Every AC unit in this borough pulls return air through a filter, and that air carries the fine powder of city soot, plaster dust from renovations, and the usual hair and lint. Over one or two summers, the evaporator coil inside the air handler grows a layer of that stuff, and the system has to work harder to move the same amount of cool air. In a Brooklyn apartment, that means higher Con Ed bills and a unit that freezes up on the first 90-degree day in July.
A proper AC cleaning here involves removing the blower wheel, cleaning the evaporator coil with a non-acidic coil cleaner, flushing the condensate pan and drain line, and treating the coil to slow future buildup. For a typical Brooklyn apartment or brownstone, expect $395 – $680 for the full system, depending on access and how fouled the coil has become. We clean the AC units in central systems, ductless mini-splits, and PTAC units alike, because Brooklyn has all three in abundance.
What we clean in an AC service
We pull the blower wheel and clean each fin, which is where the dust actually accumulates. Then we clean the evaporator coil and treat it so it sheds debris rather than collecting it. We flush the drain line all the way to the outlet, because a clogged line in a Brooklyn high-rise is exactly how you get water damage on the unit below you.
Why a coil treatment matters
The treatment is the step most “cheap” AC cleanings skip. Without it, the coil re-fouls within a season and you’re right back where you started. With it, the system holds efficiency longer, and a clean coil moves noticeably more cold air within twenty minutes of the system running again.
Evaporator Coil Cleaning in Brooklyn
Evaporator Coil Cleaning is the single most important part of getting your air conditioner to actually cool again, and in Brooklyn’s pre-war buildings it’s also the most neglected service. The evaporator coil sits inside the air handler and absorbs heat from the air passing over it. When that coil is caked in a gray mat of dust and construction debris, the refrigerant inside can’t absorb heat efficiently, so the system runs longer, blows warmer air, and can freeze into a block of ice on a humid August night. We see this constantly in older buildings on Eastern Parkway and throughout Crown Heights.
In a Brooklyn apartment, the coil is often buried behind the blower assembly, which is why so many duct cleaners skip it entirely. They clean the registers and charge per vent, and the system still blows warm. We remove the access panel, inspect the coil with a camera, apply an approved coil cleaner, and rinse the coil so the condensate drains clean. The cost for evaporator coil cleaning runs $150 – $280 as part of a full HVAC cleaning, depending on access and condition.
When a coil is beyond cleaning
Sometimes the coil is so fouled or corroded that cleaning won’t restore it. In that case, we show you the camera images, explain what we’re seeing, and quote a coil replacement with a written price before any work starts. We won’t clean a dead coil and call it done.
The source-removal difference
Here’s the trade term that matters: negative-pressure extraction. It means the loosened debris goes straight into the HEPA-filtered vacuum, not back into your living room. A Rotobrush spins the dirt loose, and a Nikro vacuum pulls it out under negative pressure. A shop vac at the register doesn’t do that. That’s the difference between cleaning and just moving dust around.
Trusted Brands We Service in Brooklyn
We service and clean HVAC systems from every major brand found in Brooklyn homes: Carrier, Trane, Rheem, Goodman, Lennox, Mitsubishi ductless systems, and the older York and Chrysler Airtemp units you still find in 1960s co-ops. When a part needs replacing, we carry Guardsman filtration products and Aprilaire media on the truck, and we can source OEM parts for most Carrier and Trane systems within 24 hours from local supply houses in Sunset Park and Gowanus. We don’t ask you to wait a week for a part that every supply house in the borough has on the shelf.
Common HVAC Cleaning Problems We See in Brooklyn Homes
- Pre-war return chases packed with debris. In 1920s and 1930s buildings, the return duct is often a hollow chase between the studs, and it’s been collecting dust and construction debris for decades. Surface vacuuming at the registers leaves most of it in place, so the system re-contaminates within weeks.
- Renovation dust from the apartment next door. Brooklyn is perpetually under renovation, and drywall dust travels through shared duct risers between apartments. We regularly clean systems where the bulk of the debris came from a neighboring unit’s gut renovation, not from the homeowner’s own living habits.
- Co-op and condo board access restrictions. In buildings like those along Prospect Park West or in Downtown Brooklyn, board approval and super coordination often add days to a job. We handle that paperwork and scheduling so you don’t have to negotiate with the super.
- Frozen evaporator coils in high-rise AC units. Window units and PTAC units in older Brooklyn high-rises frequently ice over because the coil is clogged and the drain line is blocked. A cleaning clears both issues, and a coil treatment prevents the next freeze-up.
Pricing for HVAC Cleaning in Brooklyn, NY
You should know the numbers before you call. A standard HVAC Cleaning for a typical Brooklyn apartment or brownstone runs $395 – $680 for the full system, one flat price agreed before we start. Evaporator coil cleaning alone runs $150 – $280. That price includes the blower, the coil, the drain line, and the treatment. It does not change at the door. We quote per system, never per vent, because per-vent pricing is how low-ball shops turn a $99 coupon into a $900 invoice. If the system has multiple air handlers or extreme access issues, we explain that before we begin. Call (737) 727-2314 for an exact quote; estimates are free, and the written price is exactly what you pay.

FAQs About HVAC Cleaning in Brooklyn
Every 2 to 3 years for a typical Brooklyn home, and every 12 to 18 months if the building is under renovation, if you have pets, or if anyone in the home has asthma or allergies. Pre-war buildings with original ductwork often need the first deep cleaning immediately after purchase, because decades of debris sit in the chases. The honest answer is that not every system needs cleaning every year. When we inspect your ducts, we’ll tell you if the system is actually dirty or if it can wait. Call (737) 727-2314 if you want a straight answer about your building.
Per system, always. One flat written price for the full HVAC cleaning before we start, no per-vent multipliers, no add-on charge for the air handler or blower motor once we’re already on-site. Per-vent pricing is the classic Brooklyn bait-and-switch, and we don’t play it. The price you approve before we begin is the price on the invoice.
Yes. We run Rotobrush rotary brush systems in combination with Nikro HEPA-filtered negative-pressure vacuums, and we use Abatement Technologies containment when the situation requires it. Negative pressure means debris is pulled out of the duct and into a sealed vacuum, not blown into your living room. HEPA filtration means the vacuum exhaust is cleaner than the air in the room. Both are standard on every job we do in Brooklyn, not an upsell.
Yes, including the blower wheel, evaporator coil, condensate pan, drain line, and the accessible duct runs. In a Brooklyn apartment, access to the air handler is often tight, but we carry the equipment and the experience to work in chases, closets, and behind false walls. If your building’s super or board requires documentation, we provide before-and-after photos and a work summary without a fight.
Because shoehorning a Brooklyn HVAC cleaning into a two-hour slot is how corners get cut. Parking, building access, co-op approvals, and the actual time a proper negative-pressure cleaning takes mean the job deserves a scheduled appointment. We give you a live trackable arrival window and a written price before we arrive, so the certainty you want comes from visibility, not from rushing a job in half the time it requires.
Call (737) 727-2314 for a free, no-pressure estimate on HVAC cleaning in Brooklyn. You’ll speak to a live person, get a written price before any work starts, and see photos of your own ducts when we’re finished.
