Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.
Fast, Reliable HVAC Cleaning Across Largo
HVAC cleaning in Largo, FL typically runs $380-$640 for a full-system cleaning of an average 1,600-2,200 sq ft home, with the air handler, blower, and evaporator coil included. That price is written down before a single panel comes off, and it does not change when the crew arrives. We’re CleanRun Air Duct Cleaning, and we’ve been doing this since 2013 with one rule: show the customer what’s actually inside their system before asking them to spend a dollar on fixing it. Call (806) 606-6902 for a written estimate.
Largo’s Pinellas Peninsula humidity means your HVAC system works harder here than almost anywhere in Florida. When dew points sit at 75°F from May through October, the inside of your ductwork becomes a condensation surface. We know exactly what that does to coil fins, blower wheels, and flex-duct liner in this specific climate, because we photograph it every week in homes from Clearwater-Largo Road to the 55+ communities off East Bay Drive.
Why CleanRun Air Duct Cleaning Is Largo’s Preferred HVAC Cleaning Company
We earn the work, and then we prove it was done. Every job ends with a Documented Photo Record of every duct run, before and after, delivered to you as a standard part of the job record. You do not take our word for it. You look at the camera images yourself. That practice has been in place since our first job in 2013, and it’s the reason homeowners in Largo keep our number.
Tomas Reyes, who leads CleanRun, has built the team around a simple principle: written prices, named technicians, and evidence. Our technicians are background-checked and uniformed, and you’ll know their name before they arrive. We operate under the H.A.V.E.N. Standard, with Haven Standard Clause 1 being the one you’ll care about most: a written price delivered before any work starts, every time. No call for a quote. No “well, it depends once we see it.” The price is on paper first.
For Largo specifically, that matters more than usual. The housing stock here is dominated by 1950s-1970s concrete-block homes that were retrofitted with central air decades after construction. Ducts got routed through attics that hit 140°F in July, and the flex ducts from that era were never designed for Largo’s sustained humidity. We’ve seen those systems. We know where they fail. And we know what to clean, what to seal, and what to tell you honestly needs replacement rather than cleaning.
We are independently owned and operated under the Haven Standard. Dispatch and scheduling are coordinated from our South Florida office in Miami, but the crews serving Largo work here regularly and know the streets, the neighborhoods, and the housing stock.

Before
AfterOur HVAC Cleaning Services in Largo
Our HVAC Cleaning team handles the full system, not just the ductwork. In Largo, that distinction is the difference between a clean-looking register and a system that actually moves air efficiently through the next humid season. Here’s what we do most often for Largo homeowners.
Evaporator Coil Cleaning
The evaporator coil is where condensation forms every time your AC runs, and in Largo’s marine air, that condensation carries salt and mold spores. Coils glazed with a gray film of salt-laced condensate lose heat-transfer efficiency, which means higher electric bills and longer run times. In Largo homes, we typically recommend coil cleaning at least every three years, and more often in systems that run almost continuously from May through October. We use professional-grade products from trade-recognized brands like Honeywell and Abatement Technologies.

Blower Cleaning
In a 1970s concrete-block home near Lake Seminole, our tech found the blower motor caked with a gypsum-fine dust that had been recirculating into the bedrooms, and the heat exchanger already glazed with salt-laced condensate. We used source removal with negative pressure and HEPA filtration on the supply and return ducts, then cleaned the air handler and blower, dropping visible dust fallout to near-zero in a follow-up camera inspection. That’s not a story we tell to sell. It’s what we photographed. A dirty blower wheel can lose 20-30% of its airflow capacity, which means rooms at the far end of the house get starved for air. In Largo’s concrete-block homes with long duct runs, that airflow loss is felt hardest in the bedrooms farthest from the air handler.

Condenser Cleaning
The outdoor condenser unit lives in Largo’s rain, salt air, and fine sand. Coil fins clog with a paste of pollen, sand, and salt that blocks heat rejection. We comb and clean condenser coils so the system can release heat the way it did when new. This is one of the most overlooked services in Largo, because the unit is outside and nobody sees it. But the efficiency loss shows up on your FPL bill.

Air Handler Cleaning
For Largo’s 55+ mobile and manufactured home communities, air handler cleaning is arguably more important than duct cleaning. The air handler includes the blower, the coil in many configurations, and the condensate drain pan all in one cabinet. When mold takes hold in that dark, moist space, every cycle pushes spores through the living space. We clean the entire air handler cabinet, drain pan, coil, and blower assembly. For manufactured homes especially, where the air handler sits in a cramped closet or recessed space, this requires patience and the right extraction tools.

Trusted Brands We Service in Largo

We work on systems from all major manufacturers, and we stock common wear parts for the brands most common in Pinellas County homes. On the equipment side, we run professional-grade gear from Rotobrush, Nikro, Abatement Technologies, and Guardsman. For filtration and air quality components, we work with Honeywell and Aprilaire products. You can look up any of those brands independently before agreeing to a price. We name them because they’re real, and because you should know what’s being used in your home.
Common HVAC Cleaning Problems We See in Largo Homes
- Under-floor duct runs in manufactured homes go untouched. In the 55+ parks off Ulmerton Road and East Bay Drive, ducts run through the floor belly-pan, not the attic. Standard trunk-and-branch cleaning rigs can’t access or properly seal those under-floor runs. We have the equipment and experience to clean them correctly.
- Air handlers skipped, ducts vacuumed. Some crews clean only the duct walls and leave the blower, coil, and drain pan untouched. In Largo’s salt and humidity, that means re-contamination within weeks. We clean the whole system, not just the visible parts.
- Moisture-saturated flex ducts in hot attics go unnoticed. Without a camera inspection before starting, a crew can’t see that flex-duct liner has absorbed moisture and begun to break down. We inspect first, photograph everything, and show you what we found.
- Salt and fine sand accumulation on coil fins and blower blades. Coastal air carries more than humidity. It carries airborne salt and fine Pinellas sand that settles on every surface inside the system. That grit accelerates wear on blower bearings and corrodes coil fins over time.

FAQs - HVAC Cleaning in Largo
Largo’s 55+ manufactured-home parks run ducts in the floor belly-pan, not the attic, so standard trunk-and-branch cleaning rigs can’t access or seal those under-floor runs. Our crews use specialized access tools and negative-pressure extraction designed for manufactured-home duct layouts, which is a genuine equipment difference between Largo and nearby cities with mostly attic-trunk systems. Call (806) 606-6902 to ask about your home’s specific layout.
Largo’s dew points sit at 75°F or above from May through October, which means your HVAC system cycles almost continuously and pulls coastal air through ductwork, depositing salt, mold spores, and fine sand on duct liner surfaces. In systems older than 5-7 years without cleaning, biological growth inside ducts is common. For seniors who are home all day and more sensitive to dust and allergens, we typically recommend a cleaning interval of every 3-4 years rather than the 5-7 years that might work in drier inland areas.
Cleaning removes accumulated dust, mold growth, salt deposits, and debris from the system, and that can meaningfully reduce airborne irritants. But it cannot change the outdoor air quality, and it cannot make a home with chronically high indoor humidity stop growing mold. If your home’s humidity is above 60%, we’ll tell you that a dehumidifier or air sealing matters more than another cleaning. We’d rather give you honest advice than sell you a service that won’t solve the real problem.
Yes. These homes were built without central air, and the ductwork was retrofitted through hot, poorly ventilated attics. The flex ducts from that era are often crimped, sagging, and moisture-saturated. We inspect with a camera before cleaning and photograph the condition of every run. If a flex duct is collapsed or the liner has broken down, cleaning will not fix it, and we’ll tell you that in writing so you can decide what to do next.
In manufactured homes, the air handler sits in a confined space and pulls air through the floor belly-pan, which is prone to moisture intrusion and rodent nesting. A dirty blower in that configuration recirculates whatever has accumulated under the floor directly into the living space. Blower and air handler cleaning removes that contamination at the source, and the Documented Photo Record shows you exactly what was inside before and after. Call (806) 606-6902 for a written estimate for your home.
