AfterCommercial Duct Cleaning in Fort Lauderdale, FL
Commercial duct cleaning in Fort Lauderdale typically costs between $0.18 and $0.40 per square foot, with most office and retail spaces under 5,000 square feet running $700 to $1,900. The job involves Air Duct Cleaning to remove built-up dust, mold spores, and debris from supply and return ductwork using professional negative-pressure equipment, and it usually takes one to two days depending on occupancy and access.
We’re Kestrel Air Duct Fort Lauderdale, and we’ve handled commercial ductwork in this city since 2004 under the Kingswell Guarantee. If you manage a building where the air smells stale, the vents puff dust when the AC kicks on, or your tenants keep complaining about allergies, call us at (754) 354-9798. We’ll give you a written price before any work starts. For residential needs, see our Air Duct Cleaning in Fort Lauderdale page.
Dale Whitmore leads our Fort Lauderdale operation, and he’s built the team around one idea: commercial clients deserve the same accountability homeowners get. That means a live person answers the phone at 2 a.m. or 2 p.m., the technician shows up in the window we gave you, and the price we quote is the price you pay. No exceptions.
When You Need Commercial Duct Cleaning
Most property managers don’t think about ductwork until something goes wrong. By then, the problem has been building for months or years. Here’s what we see across Fort Lauderdale commercial buildings before we’re called in:
- Dust around supply registers or on desks near vents. When ducts are packed with debris, the HVAC system pushes it into occupied spaces. If your cleaning crew dusts on Friday and it’s back by Tuesday, the ducts are the source.
- Tenant complaints about allergies, headaches, or “stuffy” air. In a humid coastal climate like Fort Lauderdale, ductwork traps moisture, which feeds mold and bacteria. Occupants notice before a walk-through ever will.
- Visible mold growth inside ductwork or on vent covers. Florida’s humidity makes condensation inside ducts nearly constant. If you can see it on the register, it’s almost certainly deeper in the system.
- Higher cooling bills without a change in occupancy. A layer of debris on the evaporator coil and inside ducts forces the system to work harder. Fort Lauderdale AC runs year-round, so inefficiency compounds fast.
- Renovation or new construction dust. Drywall dust, sawdust, and construction debris get pulled into returns during build-outs. New tenants moving into a renovated space should never inherit that.
- Odors that linger after cleaning or fresh paint. Ductwork holds smells. If the previous tenant cooked heavy food or ran a pet grooming operation, the scent stays in the ducts until they’re actually cleaned.
If two or more of these apply to your building, call (754) 354-9798. We’ll assess the system and tell you honestly whether cleaning is the right move or if the issue sits elsewhere.
Our Commercial Duct Cleaning Process
We use negative-air extraction, which means we create a vacuum inside the duct system so loosened debris gets pulled out rather than blown into your offices. We also use rotary brush agitation, which means a spinning brush scrubs the inside walls of the ductwork to break up caked-on buildup. Here’s how a typical Full System Cleaning job goes:
- Walkthrough and system map. We identify every supply and return run, locate access points, and check for asbestos-containing materials if the building predates 1980. In Fort Lauderdale, many commercial buildings from the 1960s and 70s still have original ductwork, so this step matters.
- Written price and scope. Before any equipment comes off the truck, you get a line-item price in writing. It covers the square footage, number of systems, access difficulty, and contamination level. If the scope changes during the job, we stop and put the revision in writing before proceeding.
- Equipment setup and containment. Technicians lay corner guards, use drop cloths in high-traffic areas, and seal registers not being actively cleaned. Uniformed, background-checked techs handle this part; they follow the Kingswell Way on every visit.
- Rotary brush agitation and negative-air extraction. We run a Rotobrush rotary brush system through each duct run to dislodge debris from the walls, while a Nikro negative-pressure unit pulls everything into a HEPA-filtered collection system. The Abatement Technologies HEPA filtration means loosened particles never enter your breathing space.
- Post-job verification. We photograph before-and-after conditions inside representative duct runs. You see what we removed and what the duct walls look like when we’re done. For properties with persistent air-quality concerns, we can recommend Honeywell or Aprilaire filtration products your HVAC contractor can install.
The entire process runs on your schedule. We handle after-hours and weekend work for offices, medical practices, and retail spaces that can’t shut down during business hours. Call (754) 354-9798 to confirm availability for your building.
Commercial Duct Cleaning Pricing in Fort Lauderdale
Here’s what commercial duct cleaning costs in Fort Lauderdale based on building size. These ranges reflect what we’ve quoted on similar properties since 2004:
| Building Size | Typical Range | Notes |
|---|---|---|
| Under 2,500 sq ft | $450 – $1,200 | Single HVAC system, one return trunk |
| 2,500 – 5,000 sq ft | $700 – $1,900 | Two systems or long duct runs |
| 5,000 – 10,000 sq ft | $1,400 – $3,800 | Multiple rooftop units, high ceilings |
| 10,000 – 25,000 sq ft | $2,800 – $7,500 | Large office or medical buildings |
| 25,000+ sq ft | $6,000 – $15,000+ | Priced per system and access |
What affects the final number:
- Number of HVAC systems. A 4,000-square-foot office with one rooftop unit cleans faster than the same square footage split across three units.
- Access difficulty. Ductwork above drop ceilings is straightforward. Ductwork in chases, behind fixed millwork, or requiring lifts costs more.
- Contamination level. Light dust is one pass. Heavy grease, mold, or construction debris takes multiple passes and more labor.
- Building occupancy. Fully occupied spaces during business hours require more containment and slower work than empty buildings on weekends.
- Duct configuration. Long horizontal runs, multiple floors, and flex-duct-heavy systems all change the labor equation.

FAQs – Commercial Duct Cleaning
How long does commercial duct cleaning take?
Most commercial duct cleaning jobs in Fort Lauderdale take one full day for buildings under 5,000 square feet and two to three days for larger properties. The time depends on the number of HVAC systems, how many techs we can put on the job, and whether we’re working around your business hours. We’ll give you a written timeline in the quote. Call (754) 354-9798 to discuss your schedule.
Is commercial duct cleaning worth the cost?
For most Fort Lauderdale commercial buildings, yes, especially if tenants complain about air quality or your energy bills have climbed without explanation. Clean ductwork means the HVAC system doesn’t work against built-up debris, and it removes the source of dust and odors rather than masking them. We’ll tell you honestly during the walkthrough if your ducts don’t need cleaning, and if they do, the written quote tells you exactly what you’re paying for. Call (754) 354-9798 for a free assessment.
How often should commercial ducts be cleaned?
Commercial ducts in Fort Lauderdale should be inspected every 2 to 3 years and cleaned every 3 to 5 years, more often for medical offices, restaurants, or buildings near active construction. The humidity here means mold and moisture issues develop faster than in dry climates, so annual visual checks of supply registers and Return Duct Cleaning grilles catch problems early. If you haven’t had them looked at in a while, schedule a walkthrough by calling (754) 354-9798.
Can you work after business hours?
Yes, we regularly run commercial duct cleaning jobs at night and on weekends throughout Fort Lauderdale. We know shutting down an office or retail floor during business hours costs you money, so we work around your schedule. The Kingswell Guarantee still applies no matter what time we’re there: written price, arrival window, clean job site, and written guarantee. Call (754) 354-9798 to arrange after-hours service.
Do you clean the air handler and coils too?
We focus on Residential Duct Cleaning principles applied to commercial ductwork itself: supply runs, return trunks, branch lines, and registers. Dirty evaporator coils and air handler internals are part of the same system, which is why our equipment captures what we dislodge from the ducts. If you want filtration improvements between cleanings, we can point you to Guardsman or Aprilaire products that your HVAC contractor can install. For questions about your specific system, call Dale Whitmore’s team at (754) 354-9798.
