AfterSupply Duct Cleaning in Fort Lauderdale, FL
Supply duct cleaning in Fort Lauderdale costs between $285 and $520 for a full-home service, depending on square footage, the number of supply vents, and how much has accumulated in the ductwork. The supply side is the ductwork that delivers conditioned air from your air handler to every room, and in this climate it carries more than just cooled air. South Florida humidity means supply ducts collect salt-heavy dust, fine sand, and organic matter that builds up faster than homeowners expect.
We’re Hollis Air Duct Fort Lauderdale, part of the Garrison Partners family, and we’ve handled supply duct cleaning since 2004. Our team works with negative-air machines and rotary brush systems from Rotobrush and Nikro, the same equipment commercial crews run, and every job starts with a written price before we touch a single register. If you’re seeing dust settle on furniture a day after wiping it down, or a room that never cools like the others, call us at (754) 354-3644 for a free estimate. You can also read more about what a full system involves on our Air Duct Cleaning page.

When You Need Supply Duct Cleaning
Supply ducts are the pressurized side of your HVAC system. They push air out. That means every flaw in the duct material, every gap at a joint, every layer of buildup inside gets broadcast into the rooms where you sleep, cook, and breathe. Here’s what tells us a supply-side cleaning is due:
- Dust returns within 48 hours of cleaning surfaces. In Fort Lauderdale, fine limestone dust and construction particulates settle in supply ducts and get blown through registers every time the AC cycles on. If your coffee table looks dusty two days after you wipe it, the supply side is distributing it.
- One or two rooms never reach the thermostat setting. Supply ducts that are partially blocked or lined with buildup can’t carry the designed airflow. The room farthest from the air handler, often a converted garage or an upstairs bedroom in Dania Beach or Wilton Manors, suffers first.
- Visible dust or debris at the supply registers. Remove a register cover and look inside with a flashlight. If you see gray fuzz, sand, or what looks like dryer lint along the duct walls, that material is being pushed into your living space every cycle.
- A musty or stale smell when the AC first kicks on. South Florida’s 70% average relative humidity means supply ducts can develop microbial growth faster than drier climates. The smell you catch in the first few seconds of a cycle is what’s sitting inside the ductwork.
- You’ve recently renovated or had drywall work done. Fort Lauderdale is in a constant cycle of remodeling. Drywall dust, tile grout powder, and sawdust get pulled into return ducts and pushed through supply ducts, then baked onto the walls by heat and humidity.
- You bought an older home and have no record of prior duct cleaning. Homes in neighborhoods like Victoria Park, Shady Banks, and Croissant Park often have ductwork 20 to 40 years old. If the previous owner can’t show a service record, assume the ducts are carrying years of accumulation.
Our Supply Duct Cleaning Process
We follow the same sequence on every job, and we explain it before we start so there are no surprises. Here’s how it works:
- Walkthrough and written quote. One of our uniformed technicians inspects the air handler, a sample of supply registers, and the accessible duct runs. The price is written down before any work begins, and that number does not change at the door. You approve it first.
- Register and vent protection. We seal off each supply register and cover surrounding flooring and furniture. The last thing you want in a Fort Lauderdale home is dust settling in the grout lines or on window treatments during the job.
- Negative-air setup. A Nikro negative-air machine connects to the duct system and puts it under continuous vacuum. This means any dust we dislodge gets pulled toward the collection system, not pushed into your rooms. It’s the standard method used on commercial jobs.
- Rotary brush agitation. A Rotobrush rotary brush system is fed through each supply run. The brush head scrubs the duct walls, knocking loose the compacted dust, sand, and debris that a vacuum alone cannot lift. The negative-air stays running the entire time.
- Supply register cleaning and reset. Each register cover is cleaned, dried, and reinstalled. We check that every one is open to its original setting so airflow balance in the home is not altered.
- Final walkthrough with you. We show you what came out of the ducts, verify the work is complete, and confirm the site is clean. The 365-Day Done Right Promise is applied in writing before we leave.
Supply Duct Cleaning Pricing in Fort Lauderdale
Supply duct cleaning in Fort Lauderdale runs between $285 and $520 for a standard single-family home, which aligns with our 2026 price guide for air duct cleaning. That range covers a typical 1,500 to 2,500 square foot house with 8 to 14 supply registers. The final number depends on four factors:
- Number of supply vents. More vents means more register removal, cleaning, and reinstallation time.
- Ductwork length and accessibility. Longer runs and hard-to-reach sections, common in attic-mounted systems across Fort Lauderdale, add time.
- Buildup severity. Light dust takes less time than years of compacted debris or construction residue.
- Any add-ons you choose. Some homeowners add dryer vent cleaning or duct sealing to the same visit, which changes the total.
Here’s the pricing structure we quote over the phone:
- Small home or condo (under 1,200 sq ft, up to 6 vents): $285 to $360
- Midsize single-family home (1,200 to 2,200 sq ft, 7 to 12 vents): $360 to $450
- Larger home (2,200+ sq ft, 13+ vents): $450 to $520
- Severe buildup or post-construction cleanup: add $75 to $150 depending on scope
We don’t quote a teaser price over the phone and then change it at your front door. The number we write down before starting is the number on the invoice. If you’d like a precise price for your home, call (754) 354-3644 and ask for a free estimate. Roy Castellanos and the team can often give you a firm range in a few minutes based on the size of your house and the number of vents.
What Affects Supply Duct Buildup in Fort Lauderdale
South Florida is harder on supply ducts than most places. The combination of salt air, humidity, and constant AC runtime creates conditions that accelerate buildup.
Homes within a mile or two of the ocean, including the barrier island neighborhoods off Las Olas Boulevard, get salt-laden air drawn through the system. Salt is slightly corrosive and rough, which means duct walls hold onto dust more readily. Fine beach sand also enters through windows, doors, and the return path, then gets distributed through supply ducts to every room.
Humidity is the second factor. Fort Lauderdale averages over 60 inches of rain per year and stays above 60% relative humidity most months. That moisture means airborne dust becomes heavier and stickier inside ductwork. Organic material that would stay dry and loose in Arizona or Nevada instead clings to duct walls here. Supply ducts in homes that run the AC 11 months of the year simply see more air volume pass through them, and more air equals more particles.
This is why we recommend supply duct cleaning every 3 to 5 years in Fort Lauderdale, not the national average of 5 to 7. If you have pets, live near the water, or have done remodeling work, lean toward the shorter end.
Why Hollis Air Duct Fort Lauderdale
Supply duct cleaning is not a commodity, even though plenty of companies price it like one. There are differences in equipment, method, and what happens after the job that matter in a city where every other truck has a “duct cleaning” magnet on the door.
Before we start, we perform a video inspection of your ductwork, then run Rotobrush rotary brush systems and Nikro negative-air machines. These are professional-grade tools built for HVAC contractors, not the portable vacuums sold at big-box stores. The negative-air method is the standard for commercial building maintenance because it does not release dislodged dust into the occupied space. We use the same approach in your home.
Filtration brands matter too. Depending on the work, we use filtration products from Honeywell, Aprilaire, and Guardsman. These are not proprietary to us; they’re simply the filtration components we’ve found hold up under South Florida conditions and trap the fine particulates that make people sneeze.
Then there’s the standard we hold ourselves to. It’s called The Garrison Code, and it’s how every technician from Hollis is expected to behave from the moment the truck parks:
- Arrive inside the quoted window. Not a four-hour spread. The window we give you is the window we hit.
- Write the price before touching the ductwork. If something changes scope during the job, we stop and get your approval in writing before continuing.
- Wear the uniform. You know who is in your home because we told you who is coming and what they’ll be wearing.
- Leave the site cleaner than we found it. No dust on the floor, no register covers left loose, no equipment marks.
- Back every job with the 365-Day Done Right Promise in writing. If the work isn’t right, we come back. No charge, including a second visit if the cleaning fails within a year.
Roy Castellanos has run this location under The Garrison Standard from the start, and the discipline shows in the way the work is planned, priced, and performed. We understand you’ve likely been burned by no-shows and door-price changes. That’s exactly the pattern The Garrison Standard was written to eliminate.
FAQs – Supply Duct Cleaning
How much does supply duct cleaning cost in Fort Lauderdale?
Supply duct cleaning in Fort Lauderdale costs between $285 and $520 for a typical single-family home, with small condos starting around $285 and larger homes running up to $520. The final price is written down before work starts and depends on vent count, duct length, and buildup severity. Call (754) 354-3644 and we’ll give you a firm range for your home over the phone.
Can you clean just the supply ducts and not the return ducts?
We can clean the supply side alone, and some homeowners in Fort Lauderdale choose that option when a previous service already addressed the return side. That said, pushing air through clean supply ducts while pulling air through dirty return ducts just re-contaminates the system within a few months. We’ll quote both options and let you decide.
How long does supply duct cleaning take?
A standard supply duct cleaning in Fort Lauderdale takes 2 to 4 hours depending on the number of vents and the condition of the ductwork. Larger homes with extensive buildup or accessible attic sections may run longer. We’ll give you a time estimate with your written quote before the job begins.
Is it cheaper to clean supply ducts or replace them?
Cleaning supply ducts at $285 to $520 is significantly cheaper than replacing them, which in Fort Lauderdale generally starts around $1,800 for a partial run and goes well beyond $5,000 for a full system replacement. Duct replacement makes sense when ductwork is crushed, torn, or rusted through; cleaning is the right call for buildup, dust, and debris. If you have old flex duct that’s degraded, our Air Duct Cleaning in Fort Lauderdale page covers what full-system work involves.
