Why Miami Homeowners Choose Carrier Air Duct Cleaning
We provide independent Carrier Air Duct Cleaning services in Miami for Infinity, Performance, and Comfort series systems. Our Carrier work is different because we clean the system the way Miami’s climate demands it be cleaned: we treat the coil, air handler, supply plenum, and duct runs as one connected airflow path, not as separate boxes to vacuum. Call (850) 660-3272 for a free estimate.
Let’s be clear up front: Hollis Air Duct Miami is not authorized by Carrier, and we don’t pretend to be. We’re an independent service provider that works on Carrier ducted systems across Miami Beach Carrier service areas and Miami-Dade every week. What that means for you is simple. We diagnose what we can see, measure, and clean ourselves. No factory line to call, no waiting on a vendor rep. Roy Castellanos has been running crews through Brickell high-rises and older Coral Gables homes for well over a decade, and the humidity down here taught him things no classroom covers. If you can’t explain the job plainly, you probably shouldn’t be doing it. We live by that.
Carrier builds good equipment. But in Miami, even good equipment fights a losing battle against salt air, constant humidity, and ductwork that was often installed decades ago. We’ll get into the specifics below, but the short version is this: your Carrier system’s ducts tell us exactly what’s happening inside the unit, and cleaning them properly means understanding how Infinity, Performance, and Comfort lines each fail differently in this climate.
Why Trust Hollis Air Duct Miami for Your Carrier Air Duct Cleaning?
Our technicians work on Carrier ducted systems across Miami-Dade every week, from older Infinity air handlers to newer Performance series furnaces and Comfort packaged units. We know how their airflow, filtration, and humidity control interact with duct buildup. That field experience lets us clean and recommission Carrier systems without vendor authorization or factory training, because we diagnose what we can see, measure, and clean ourselves.
Roy Castellanos picked up his trade fundamentals at Los Angeles Trade-Technical College before spending years working HVAC and duct systems across Southern California. He’s been in Miami long enough to know that a Carrier Infinity air handler in a Pinecrest attic behaves differently than the same unit in a Brickell condo closet. Different access, different airflow, different failure points. When we send a tech to your Carrier system, that tech has seen your exact setup before, probably dozens of times.
Every Carrier cleaning job gets a written price before work starts. That price does not move at the door. We use professional-grade equipment from Rotobrush, Nikro, Abatement Technologies, and filtration brands including Honeywell, Aprilaire, and Guardsman, the same tools commercial crews use. And every job carries the 365-Day Done Right Promise in writing: if the work fails within a year, we come back at no charge, including a free second visit. That’s The Garrison Standard, and it’s how we’ve operated since 2004.

Common Carrier Air Duct Cleaning Problems We Fix in Miami
- Mold and biofilm on Infinity evaporator coils. Miami humidity causes mold and biofilm on Carrier evaporator coils, especially on Infinity systems running constant-fan mode. The coil stays wet, the fan keeps moving warm moist air across it, and within months you’ve got gray sludge breaking off and accumulating in supply ducts. We pull the coil, clean it with the right chemistry, and wash the downstream plenum. Skipping the plenum is the mistake most crews make.
- Short-cycling condensers leaving return ducts damp. Oversized Carrier condensers short-cycle in South Florida. The unit cools the house too fast, never runs long enough to dehumidify, and return ducts stay damp, which encourages fungal growth inside flex runs. We see this constantly in older Coral Gables homes where the original ducts are still in place and the condenser was upsized at some point without redoing the ductwork.
- Loose fiberglass insulation clogging Infinity blower wheels. Carrier Infinity air handlers mounted in hot Miami attics pull loose fiberglass insulation into return ducts. That insulation shreds, gets past cheap filters, and packs itself onto the blower wheel. Airflow drops, the system runs longer, and your electric bill climbs. We clean the wheel, then seal the return duct connections so it doesn’t happen again next year.
- Rust flakes from older Performance series heat exchangers. Salt in Miami’s air corrodes metal, period. Older Performance series heat exchangers rust in coastal salt air, and during brief winter heat calls, those rust flakes shed into supply ducts. If you’ve ever noticed reddish dust around your supply registers after running the heat, that’s what you’re seeing. We clean the ducts and flag the heat exchanger condition so you know what you’re dealing with.
- Mold colonies on flex duct liner in supply plenums. The area right after the coil is where Miami’s condensation problems turn into visible mold. We opened a Carrier Infinity air handler in a Pinecrest home where the homeowner ran the fan 24/7 for humidity control. The evaporator coil was coated in gray biofilm, and the downstream supply plenum had visible mold colonies on the flex duct liner. We pulled and cleaned the coil, washed the supply plenum, then sealed the duct connections with mastic. After a video inspection, the system was moving 22% more airflow at the same static pressure. That’s the kind of measurable result we document on every job.
Carrier Parts & Our Repair-vs-Replace Approach
For Carrier systems, we always clean and reuse OEM components like Infinity blower wheels or Performance filter racks unless they’re cracked, warped, or corroded beyond cleaning. That’s the honest approach. If a part can be cleaned and returned to spec, we clean it. We don’t sell parts you don’t need.
When replacement is unavoidable, we use quality aftermarket parts that fit properly, never counterfeit Carrier-labeled parts. There’s a big difference. A properly made aftermarket blower wheel from a reputable supplier will fit correctly and balance true. A counterfeit part stamped with the Carrier logo is a gamble, and we won’t put that in your system.
Sometimes the right call is neither cleaning nor replacing a part. It’s telling you straight: the duct run is rusted through from decades of salt air, or the air handler is past saving. We’ll tell a homeowner when a repair is a band-aid versus a sign the duct run or air handler needs replacement. That’s what Roy means when he says he’d rather explain a price once than defend a bill twice. Call (850) 660-3272 and we’ll look at your Carrier system before recommending anything.
Our Carrier Service Process – Step by Step
- 1
Diagnosis. We start by looking at your specific Carrier setup. Is it an Infinity air handler in an attic or a Performance packaged unit on a condo balcony? Each has different access points and different failure patterns in Miami. We measure static pressure, check the filter rack, and note what model series you’re running before anything gets touched.
- 2
Write the price. After diagnosis, you get a written price for the specific work your Carrier system needs. Evaporator coil cleaning, air handler cleaning, duct sealing, whatever the job requires. That number is the number. It doesn’t change once we start.
- 3
Clean and recommission. We use negative-air machines and rotary brush systems sized for your duct layout. For Carrier systems, evaporator coil cleaning and air handler cleaning are often the difference between a job that lasts and a job that just vacuums ducts. We also apply duct sealing mastic where connections leak, which is common on older systems.
- 4
Test and verify. We check airflow at the registers, verify the system cycles correctly, and document everything with before-and-after photos. You see what we saw and what we did.
- 5
Warranty in writing. Every Carrier service gets the 365-Day Done Right Promise. If the work fails within a year, we return and make it right at no charge. That includes a free second visit if needed.

FAQs – Carrier Air Duct Cleaning Service in Miami
No, we are not authorized by Carrier. We are an independent Carrier service provider. That means we diagnose and clean your system based on field experience and direct measurement, not factory training or vendor authorization. For most duct cleaning and coil work, what matters is that the crew knows the equipment and does the job correctly, not whose logo is on their van.
We clean and reuse OEM Carrier parts whenever possible. When replacement is necessary, we use quality aftermarket parts that fit properly, never counterfeit Carrier-labeled parts. If your Infinity blower wheel is warped beyond cleaning, the replacement will be a properly manufactured part, and we’ll show you the old one before we install the new one.
That musty smell almost always comes from mold and biofilm on the evaporator coil, not the filter. Miami humidity keeps the coil wet, and the Infinity’s constant-fan mode keeps warm moist air moving across it. The smell comes from the coil and the supply plenum directly downstream. Changing the filter won’t touch it. The coil needs to be pulled and cleaned, and the plenum needs to be washed. Call (850) 660-3272 for an exact quote.
Yes, often by a measurable amount. When a Performance system’s ducts are lined with dust, salt residue, and fiberglass shedding, the system works against restriction. Cleaning the ducts and the blower wheel reduces static pressure and increases airflow. In the Pinecrest job we just described, the system moved 22% more airflow at the same static pressure after cleaning and sealing. That’s real capacity recovery, and it’s documented on video.
Yes. Infinity air handlers are more often mounted in attics or closets where return ducts pull in fiberglass and humidity is harder to control. They also run constant-fan mode more often, which means the coil stays wetter longer. Comfort series single-stage systems cycle more, so the ducts see different buildup patterns. A crew that treats them identically is leaving work on the table.
Usually yes, especially if the ducts are original from the 1950s to 1970s and show rust or loose connections. Leaky ducts pull attic air, which in Miami means humid, dusty, fiberglass-laden air. Sealing the connections with mastic reduces the load on the system and keeps the air you’re breathing moving through the duct, not picking up attic dust along the way. Call (850) 660-3272 for a written assessment.
In Miami’s climate, annual cleaning is the realistic standard for most Carrier systems. The humidity and salt air don’t take a year off. If your system runs constant fan for humidity control, twice a year is not unreasonable. The key is inspecting what’s there, not cleaning on a fixed schedule blindly. We’ll show you before-and-after photos so you can see what was actually in your ducts and decide for yourself. Estimates are free at (850) 660-3272.
