We’re Hollis Air Duct Miami, an independent Guardsman service provider. That means we clean and maintain ducts behind Guardsman filtration products, but we’re not affiliated with or authorized by Guardsman. We’re part of the Garrison Partners family, operating since 2004 under The Garrison Standard: arrive inside the quoted window, price in writing, do the job by the book, leave the site clean.

How Guardsman Products Fail – and How We Fix Them

Guardsman filtration products handle the air after it leaves your ducts. The problem we see in Miami is that the ductwork feeding those filters gets ignored until the system starts fighting itself. Here’s what we actually find on Guardsman jobs:

• Guardsman media cabinet filters loading up fast in humid months. The Guardsman media cabinet line, common in Miami homes, uses deep-pleat filters that catch more than standard one-inch filters. That’s good for air quality but bad when ducts upstream haven’t been cleaned: the filter loads up in 30 to 45 days instead of 90. We pull and inspect the media cabinet during every duct cleaning, document the loading pattern, and recommend a cleaning schedule based on what’s actually in your ducts, not a calendar guess.
• Return-side duct debris causing filter collapse. If your return ducts carry heavy dust and dander loads, the negative pressure on a Guardsman media filter can cause the pleats to fold or crack. In Coral Gables homes with older return ducting, we see this regularly. The fix starts with cleaning the return side properly, which most duct cleaners short-change because they only hit supply registers. We clean both sides and document the filter condition before and after.
• Condensation issues on Guardsman UV systems in South Florida humidity. Guardsman UV air treatment systems installed downstream of the coil see condensation year-round in Miami. When ducts are dirty, that moisture binds with dust and creates a paste that corrodes duct interiors and shortens UV lamp life. We inspect the duct run around any UV system during cleaning and flag moisture issues before they become mold problems.
• Restricted airflow from plugged Guardsman electronic air cleaner cells. Homes with Guardsman electronic air cleaners often have washable cells that haven’t been washed in months because owners don’t know they exist. Dirty cells restrict airflow, which pulls more debris through the ducts. We show owners where the cells are, explain the wash cycle, and verify airflow after cleaning so the system isn’t choking on its own lack of maintenance.
• Flex duct sagging in attic runs above Guardsman whole-house filtration setups. Miami attics hit 130-plus degrees in summer. Flex duct that was never strapped correctly sags and pools dust in the low spots. On Guardsman whole-house filtration jobs, that pooled dust breaks loose in clumps and blinds the filter downstream. We check duct runs visually during every cleaning and flag sagging runs, because a clean filter doesn’t help if the duct feeding it is holding a dust reservoir.

Our Guardsman Air Duct Cleaning Process

Every Guardman job follows the same sequence, whether it’s a condo in Brickell or a house in Pinecrest. You’ll know what’s happening at each step and what it costs before we touch anything.

1. 1
   Call and schedule. A live person answers at (850) 660-3272. You tell us your system type, square footage, and whether you have a Guardsman filtration product. We give you a written price range over the phone based on system size, not a teaser number.
2. 2
   On-site walkthrough. Roy Castellanos or a technician from his crew walks the system with you. We look at the registers, return drops, filter cabinet or air cleaner, and any UV setup. We document what we find, including problems you didn’t call about.
3. 3
   Written flat-rate quote. You get one price per system in writing before any equipment comes off the truck. It covers supply and return cleaning, blower compartment inspection, and filter inspection. It does not change at the door.
4. 4
   Negative-air cleaning with rotary brush agitation. We use Nikro negative-air machines to pull vacuum on the system while Rotobrush rotary brushes dislodge debris from duct walls. The negative pressure keeps dust from blowing into your living space. On Guardsman filtration homes, we also protect the media cabinet or electronic cells during the process so we don’t blast debris into a filter you just replaced.
5. 5
   Filter and airflow verification. After cleaning, we inspect the Guardsman filter media or cells, verify airflow at several registers, and take before-and-after photos. You see what came out and what the ducts look like now.
6. 6
   Written guarantee. Every job includes the 365-Day Done Right Promise in writing. If something isn’t right within a year, we return and make it right at no charge, including a free second visit.
