Frequently Asked Questions - Air Duct Cleaning in Miami, FL
Straight answers to the questions Miami homeowners ask us most about air duct cleaning. If you don't see yours here, call (850) 660-3272 and our coordinator will get you an answer.
Pricing & Cost FAQs
Most single-family homes in Miami pay between $350 and $650 for a full-system air duct cleaning, with larger homes in neighborhoods like Palmetto Bay or Aventura running higher because of extra vent runs and square footage. Condos in Brickell or Sunny Isles Beach often fall at the lower end. Every Hollis Air Duct Miami quote is a flat price per system, written down before any work starts, so the number you agree to is the number you pay. Call (850) 660-3272 for a free written estimate for your place.
Because some operators price per vent as a teaser, then "find" extra work once they're inside the home. A $49 whole-house coupon becomes a $900 invoice the moment a camera comes out. That's the bait-and-switch reputation this industry earned, and it's exactly why we write one flat price per system before the job begins. No per-vent math, no surprise add-ons. If a quote sounds too cheap to sustain real truck-mounted equipment and trained labor, it usually is.
Miami's year-round moisture means dust inside ductwork turns into a damp, sticky film faster than it does in drier climates. That film traps mold spores and allergens, and it's the reason homes in Miami Lakes, Kendall, and West Little River often need cleaning more frequently than homes in Arizona or Nevada. The cleaning itself doesn't cost more because of humidity, but neglecting it has a higher dust-and-mold penalty here. A written quote accounts for system size, not the weather.
No. The inspection is part of the free written estimate. We check the return and supply plenums, the blower cabinet, and a sample of vent runs, then put the flat price in writing. If you don't book, you owe nothing. If you do book, the price on that paper is the price. That's The Garrison Standard, and it applies to every home we service in Miami, Miami Beach, and Doral.
Three things move the price most: the number of vent runs, whether the system is a single-zone or multi-zone setup, and how much buildup has accumulated on the blower and coils. A 1,800-square-foot home in Tamiami with one system and standard buildup will usually land in the middle of the price range. A two-system home in Palmetto Bay with years of pet hair and dust will push higher. Every quote reflects the actual system, not a generic chart. Call (850) 660-3272 to schedule the free estimate.
Service & Process FAQs
A truck-mounted vacuum creates negative pressure on the ductwork while rotating brushes agitate dust off the duct walls. We seal each register, work the full run of the supply and return lines, clean the blower cabinet, and finish by wiping the vent covers. The whole process takes three to five hours for a typical single-family home in Miami. You get before-and-after photos of your own ducts so you can see the work was done, not just take our word for it.
Most homes in Miami, Miami Gardens, and Fountainebleau take between three and five hours from setup to final walkthrough. Larger homes with two HVAC systems or heavy buildup can run longer. The estimate appointment usually takes 30 to 45 minutes. We schedule in a window and show up inside it, so you're not stuck waiting half a day wondering where the van is.
You don't need to be home for the entire job, but we do need you there for the first few minutes to confirm access and walk through the system with the lead tech. After that, you can come and go as you please. The crew wraps up with a walkthrough and your before-and-after photos. Most homeowners in South Miami and Aventura stick around for the first and last half hour.
It shouldn't. The negative-pressure setup pulls dust into the collection unit, not into your living room. We lay drop cloths at every register we open and around the equipment access points. Before we leave, the site is swept and squared away. The Garrison Code includes leaving the site clean, and that's not a bonus feature. It's the standard.
Move anything fragile off the floor near your main return and the HVAC closet, and make a note of any rooms you've noticed are dustier than others. That's genuinely it. You don't need to move furniture out of every room or tape anything up. The techs handle access to registers, including ones behind beds or under desks, and they put everything back the way they found it.
Every three to five years for most homes, though Miami's humidity and the constant air conditioning load push many households toward the three-year side of that range. Homes with heavy pet dander, recent renovation dust, or a smoker in the house should lean shorter. Condos in Miami Beach and Sunny Isles Beach that share building chases can pick up neighbor dust and may need attention sooner. If you're seeing dust resettle within days of cleaning surfaces, the ducts are overdue.
Ask for before-and-after photos of your own ductwork. Any legitimate company can provide them, and we include them on every single job. If a company refuses to show you the inside of your ducts after they claim to have cleaned them, that's your signal to walk away. Our photos are taken with the same camera we used for the inspection, so you see the same angles, same runs, clean metal where there used to be buildup.
Brands & Parts FAQs
We run commercial truck-mounted vacuum systems paired with rotary brush agitation, using equipment from Rotobrush and Nikro, two names that set the bar in this trade. The vacuum pulls continuously while the brush works, so dust doesn't get kicked into your living space. Small drill-attachment brushes that a handyman might use simply can't create the negative pressure needed to actually extract debris from a full residential system in Miami.
No. Whether your system is a Trane, Carrier, Rheem, or Goodman, the ductwork is ductwork. The process is the same. What matters more is whether the cleaning includes the blower cabinet and coil, which is where Miami's humidity causes the most buildup. Our flat per-system price covers the full system regardless of HVAC brand. Honeywell filtration add-ons are compatible with any setup and worth considering if your home struggles with allergy season.
We clean dryer vents as a separate service, and in Miami it's one we recommend every year. Lint buildup in a dryer vent is a fire risk, full stop. The humid air doesn't help, and long vent runs common in older Miami homes trap lint faster. If you've never had yours cleaned, or you've noticed the dryer taking longer to finish a load, have it checked. The service is quick and the alternative is a house fire waiting in the wall.
We don't use chemical sprays or deodorizers during a standard duct cleaning. The process is mechanical: agitation plus extraction. In some cases a homeowner may request an antimicrobial fogging for mold remediation, and that product has a safety data sheet we can provide before the job. But for a standard cleaning, nothing enters your home's air that wasn't already there. No heavy fragrances, no residue, no fumes. Just cleaner air, from the vents on out.
Licensing & Insurance FAQs
Every pro working under the Hollis Air Duct Miami name is required to hold the license and insurance their state requires for this trade. We don't send unlicensed help into your home. Before any job starts, the lead tech arrives with credentials in the van and the insurance documentation our office has on file. If you want to see the policy before the crew arrives, our coordinator can send it over. That's a reasonable ask, and we treat it as one.
No. Florida doesn't require a specific air duct cleaning license at the state level, but legitimate operators carry business insurance, workers' compensation, and often an HVAC or mechanical contractor's license at the county level. Anyone who can't show insurance puts you at financial risk the moment something goes wrong in your home. The job involves climbing into attics, moving around your HVAC equipment, and working near electrical components. Hire someone who's covered, full stop.
Roy Castellanos leads the Miami branch. Roy's job is simple: make sure every job meets The Garrison Standard and every homeowner gets the written price we promised. The Miami location is part of the Hollis Air Duct Cleaning family, a brand under the Garrison Partners umbrella, and this branch operates independently within that network. Roy and the local crew answer to Miami homeowners, not to a distant corporate office.
Emergency & Response FAQs
Yes, and in Miami after a hurricane or flood, that call happens more than you'd think. We handle post-water-intrusion and post-fire duct cleaning, which involves removing debris, sanitizing where needed, and making sure the system isn't circulating soot or contaminated dust. This isn't the same as a standard cleaning and takes longer to quote, but it's work we're set up to do. Call (850) 660-3272 and let our coordinator know the situation.
We schedule and run jobs Monday through Friday from 7:00 AM to 7:00 PM, and Sunday from 7:00 AM to 7:00 PM. Saturdays we're closed. Our coordinator answers calls during those published hours. There's no 24-hour hotline and no overnight crew. What there is: a reliable live person on the phone during the hours above who will get you on the schedule and connect you with the local team.
Scheduling depends on our booked calendar and your neighborhood. Homes in central Miami, Miami Lakes, and Doral are usually easier to slot in the same week. South Dade and the beach communities can add a day or two of drive time. The best move is to call (850) 660-3272 and ask for the current availability in your zip code. We'll give you a window and show up inside it.
Warranty & Guarantees FAQs
The work is guaranteed in writing for a full year. If anything we cleaned fails to stay clean, or if we missed a section of ductwork during the job, we come back and make it right at no charge. That's The Garrison Standard, and it applies to every system we clean in Miami, Miami Beach, Miami Gardens, and the rest of our service area. The guarantee follows the home, so if you sell, the next owner gets the same protection.
You call (850) 660-3272 and tell us what's wrong. We schedule a return visit inside the same week and fix it. The guarantee isn't a warranty card that lives in a drawer; it's the promise we make on every job. Roy Castellanos and the team take a callback on our own work personally. If we didn't do it right the first time, returning is on us, not on you.
Yes. The price we give you before work starts is the price you pay when the job is done. That's a core part of The Garrison Code: price in writing before any work starts. If we discover something unexpected during the job that genuinely needs attention, we stop, show you, explain it, and get your approval before doing anything extra. The flat price per system is the contract, and we treat it like one.
