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.
Air Duct Cleaning in Largo, FL
Dryer vent cleaning in Largo means dealing with a specific combination of 1960s concrete-block homes, retrofitted duct runs through hot attic spaces, and Pinellas Peninsula humidity that keeps vents damp for months at a time. Lint that would stay dry and brittle in a northern climate stays soft and sticky here, bonding to vent walls and trapping the sand and salt that blows off the Gulf. That shortens safe vent-cleaning intervals and makes a documented photo record the only honest way to confirm the job was actually done. Call (806) 606-6902 for a written price.
Why Largo Homes Are Different
Largo sits on a peninsula with water on three sides. Dew points from May through October commonly reach 75°F or above, and HVAC systems cycle almost constantly. Every cycle pulls coastal air into the return side of the system, depositing airborne salt, mold spores, and fine sand onto coil and duct surfaces. In an unconditioned attic that hits 140°F in summer, that combination accelerates flex-duct liner breakdown and makes biological growth inside ductwork a near-certainty in systems older than 5 to 7 years without service.
The housing stock compounds the problem. Largo’s dominant homes are 1950s to 1970s concrete-block construction, most originally built without central air. Ductwork was retrofitted later through hot, poorly ventilated attics, leaving flex ducts crimped, sagging, and saturated with moisture. Many of those runs are now 15 to 25 years old, serving long-term residents who moved in decades ago and have never had the system opened. The area also has one of Pinellas County’s highest concentrations of 55+ manufactured-home communities, where duct systems run through floor belly-pans rather than attics and collect condensation, rodent nesting, and collapsed insulation in ways standard trunk-and-branch equipment cannot reach.
Our Main Largo Services
Two services dominate the call volume from Largo homeowners, and each has a dedicated page covering the job in full local detail.
Air Duct Cleaning in Largo
Whole-system duct cleaning in Largo addresses what the peninsula’s air leaves behind: salt film, fine sand, mold spores, and the dust of aging flex-duct liner. Our crews photograph every accessible run before and after cleaning, so the difference between extracted debris and untouched return air is visible in the job record. Learn more in the complete Largo guide: Air Duct Cleaning in Largo.

HVAC Cleaning in Largo
HVAC cleaning covers the blower assembly, evaporator coil, condensate pan, and plenum, plus the duct runs themselves. In Largo’s continuous cooling season, a 1/8-inch layer of bio-film on a coil raises runtime and keeps damp air moving through the system longer. Read the full service breakdown at HVAC Cleaning in Largo.

AfterDryer Vent Cleaning in Largo

Dryer vent cleaning in Largo is the service most tied to both housing age and climate. Original or first-generation vents in 1960s and 1970s concrete-block homes run long distances through walls and attics, gathering lint around every bend, while the peninsula’s constant dampness turns that lint into a dense, adhesive mat. In manufactured-home communities off Ulmerton Road and East Bay Drive, vents are typically short but hidden in floor cavities, making inspection and cleaning a job for crews who know manufactured-home layouts. Our Dryer Vent Cleaning service always includes before-and-after photos of the inside of the vent run.
Dryer Vent Inspection
Signs you need it
Clothes take two or more cycles to dry, the dryer exterior runs hot, or you cannot remember the last time anyone looked inside the vent run.
What it costs in Largo
A camera-assisted dryer vent inspection in Largo runs $89-$149 when booked as a standalone service and is included with every full vent cleaning.
How we do it
We run a camera through the full vent path from dryer collar to exterior termination, marking restrictions, moisture staining, and any disconnection on a written report.
Vent Cleaning
Signs you need it
There is visible lint at the exterior hood, a burning smell when the dryer runs, or the vent cap does not open fully during operation.
What it costs in Largo
Standard dryer vent cleaning in Largo runs $129-$199 for a single-dwelling vent up to 15 feet, with longer runs priced by written addendum before work starts.
How we do it
We run a HEPA-filtered negative-pressure extraction system from the exterior termination back to the dryer, brushing and vacuuming the full run until the camera shows clear vent walls.
Lint Removal
Signs you need it
You find dry, flaking lint packed inside the dryer cabinet, around the lint trap housing, or in the interior of the machine itself.
What it costs in Largo
Interior dryer lint removal in Largo runs $99-$179 when bundled with vent cleaning, depending on cabinet disassembly requirements.
How we do it
We open the dryer cabinet, vacuum lint from the blower housing and internal chassis, and photograph the interior before reassembly.
Vent Rerouting
Signs you need it
Your current vent exceeds 25 equivalent feet of run, uses flexible foil duct, or terminates in a soffit vent that recirculates moist air into the attic.
What it costs in Largo
Vent rerouting in Largo starts at $225 for simple repositioning and runs up to $450 for full replacement with rigid duct through new termination points.
How we do it
We measure the existing run, calculate equivalent length, and replace flexible or undersized duct with rigid metal pipe at the shortest safe path to a compliant exterior hood.
Bird Guard Installation
Signs you need it
There are birds, nesting material, or droppings visible at the vent hood, or you hear scratching from the exterior wall when the dryer is off.
What it costs in Largo
Bird guard installation in Largo runs $75-$125 per vent when added to a cleaning, including the louvered hood assembly.
How we do it
We remove debris, install a louvered guard with a screen aperture sized for vent airflow, and seal the mounting face against water intrusion.
What Dryer Vent Cleaning Costs in Largo
| Item | Typical range in Largo |
|---|---|
| Camera inspection | $89-$149 |
| Standard vent cleaning (up to 15 ft) | $129-$199 |
| Bird guard installation | $75-$125 |
How often should a dryer vent be cleaned in Largo?
Every 12 to 18 months for most Largo homes, and every 12 months when the vent runs through an unconditioned attic or a manufactured-home floor cavity. The peninsula’s humidity keeps lint adhesive longer than in drier climates.
Does Largo’s humidity make dryer vents clog faster?
Yes. Lint that stays damp from May through October clings to vent walls and hardens as it dries between cycles. Vent runs that would remain clear for 3 years in a dry climate can restrict significantly within 12 months here.
Duct Repair & Sealing in Largo

Duct repair and sealing in Largo is rarely a small job, because the original or first-generation ductwork in most peninsula homes has already passed its reasonable service life. Flex ducts crammed through hot attics sag between straps, their inner liners split, and the mastic at every joint dries and cracks under 140°F attic temperatures. A sealed duct system in Largo is not just about comfort; it prevents humid attic air from being pulled into conditioned space every time the air handler cycles. Our Duct Repair & Sealing crews document every repair with photos and a written scope before work begins.
Duct Sealing
Signs you need it
Rooms at the end of the duct runs never reach set temperature, energy use climbs in summer, or you see dust streaks around supply registers and return grilles.
What it costs in Largo
Whole-system duct sealing in Largo runs $350-$800 for an average single-family home, depending on accessible duct length and joint count.
How we do it
We locate leaks with a pressure test and visual inspection, then apply fiberglass-reinforced mastic or foil tape at every accessible joint and connection.
Flex Duct Repair
Signs you need it
Flex duct in the attic is visibly sagging, kinked, or split at the inner liner, or a room suddenly receives weak airflow after years of adequate delivery.
What it costs in Largo
Flex duct repair in Largo starts at $150 for a short section and runs up to $450 when an entire branch requires replacement and re-strapping.
How we do it
We remove the damaged section, replace it with new R-6 or R-8 flex duct, and re-strap every connection to support spacing specified in current code.
Metal Duct Repair
Signs you need it
There is visible rust, crushed sections, or disconnection at a metal trunk line in the attic, crawl space, or garage chase.
What it costs in Largo
Metal duct repair in Largo ranges from $200-$600, priced by the linear section and complexity of access.
How we do it
We cut out the damaged section, fabricate or source a matching replacement, and seal the transition with mechanical fasteners and mastic.
Duct Insulation
Signs you need it
Bare or damaged duct surfaces in an unconditioned attic, condensation visible on the duct exterior, or supply air arriving noticeably warmer than the register.
What it costs in Largo
Duct insulation in Largo runs $250-$650 for accessible duct runs, including wrap or upgraded flex replacement by the linear foot.
How we do it
We wrap exposed ducts in fiberglass or closed-cell insulation, sealing all seams and securing the insulation to prevent sagging or compression.
Mastic Sealant
Signs you need it
Hand-testing reveals air moving at duct joints, or the existing sealant is cracked and separating from the duct surface after years of attic heat.
What it costs in Largo
Mastic sealant application in Largo runs $150-$400 for a full accessible system, including joint prep and two-coat coverage.
How we do it
We clean joint surfaces, apply fiberglass-reinforced mastic, and document every sealed connection with photos for the job record.
What Duct Repair & Sealing Costs in Largo
| Item | Typical range in Largo |
|---|---|
| Whole-system duct sealing | $350-$800 |
| Flex duct repair | $150-$450 |
| Metal duct repair | $200-$600 |
How do I know if my ducts are leaking in Largo?
Check for dust streaks around registers, uneven room temperatures, and higher summer bills than neighbors with similar homes. A pressure test or visual inspection with a camera confirms the exact leak points.
Is duct sealing worth it in Largo’s humidity?
Yes. Every leak on the return side pulls attic air into the system, which means you are paying to cool and dehumidify attic air, not house air. Sealed ducts in Largo also reduce mold spore intake from unconditioned attics.
Air Quality & Sanitizing in Largo

Air quality and sanitizing in Largo is a direct response to what the peninsula climate leaves behind: sustained dew points above 75°F, HVAC systems that run most of the year, and duct interiors that collect salt, sand, and biological growth. By the time a homeowner notices a musty smell at the registers or a persistent cough that improves away from home, the microbial load inside the system is already established. Our Air Quality & Sanitizing service pairs source removal with EPA-registered antimicrobial treatment, documented with the same before-and-after photo record as every other job.
Mold Treatment
Signs you need it
Visible mold growth inside duct boots or on the coil, a persistent musty odor from registers, or allergy symptoms that consistently worsen indoors.
What it costs in Largo
Mold treatment in Largo runs $275-$650, depending on the linear duct footage affected and whether the coil requires separate treatment.
How we do it
We remove visible contamination with HEPA-filtered extraction, apply an EPA-registered antimicrobial labeled for HVAC use, and photograph the treated surfaces.
Bacteria Sanitizing
Signs you need it
Recurring condensation in the condensate pan, a damp sock smell from the supply vents, or a technician has flagged biological film on the coil and pan.
What it costs in Largo
Bacteria sanitizing in Largo runs $200-$450, including the coil, pan, blower housing, and accessible duct surfaces.
How we do it
We clean the coil and pan first, then apply an EPA-registered sanitizer labeled for evaporator coil and duct surfaces, documenting final condition with a photo record.
Odor Removal
Signs you need it
There is a persistent smell from the ducts that matches no single source: cigarette residue, former pet urine, decades of cooking grease, or a general stale-air odor at start-up.
What it costs in Largo
Duct odor removal in Largo runs $225-$500 when paired with full duct cleaning, depending on the odor source and required treatment pass.
How we do it
We identify the source with a camera, remove any remaining debris, and apply an odor-neutralizing treatment rated for porous duct surfaces.
UV Light Installation
Signs you need it
You have had more than one coil-cleaning or mold-treatment visit, or your condensate pan and coil area stay damp even during short cooling cycles.
What it costs in Largo
UV light installation in Largo runs $350-$850, including the unit and direct wiring with a dedicated ballast.
How we do it
We mount the UV lamp upstream of the coil in the supply plenum, wire it to cycle with the blower, and verify lamp output with a sensor reading.
Air Purifier Install
Signs you need it
You want active air cleaning after duct and coil remediation, or a household member has a respiratory condition that makes portable units insufficient.
What it costs in Largo
Air purifier install in Largo runs $400-$1,200 depending on the unit and whether it integrates with existing controls or runs as a standalone cabin unit.
How we do it
We install the purifier in the supply plenum or return, wire it to the blower control circuit, and document the installation with photos and a written warranty.
What Air Quality & Sanitizing Costs in Largo
| Item | Typical range in Largo |
|---|---|
| Mold treatment | $275-$650 |
| Bacteria sanitizing | $200-$450 |
| UV light installation | $350-$850 |
Will sanitizing really remove mold from Largo ducts?
Yes, when combined with source removal. Antimicrobial treatments kill surface growth but do not remove the dead biomass. We remove the contamination first, then treat the cleaned surface. That order matters.
Do I need a UV light if my ducts have been cleaned?
Only if you have a recurring moisture problem at the coil. In Largo’s humidity, the coil is often wet even between cycles, and UV lights are useful for that specific condition. They do not replace duct cleaning.

Routine duct cleaning, vent cleaning, and sanitizing do not require a permit in Largo. Duct replacement or rerouting inside conditioned or unconditioned space typically falls under mechanical work that may require a permit, depending on scope. We advise on permit requirements by the specific job and never skip the approval process.
Yes. Largo has one of Pinellas County’s largest concentrations of 55+ manufactured-home communities, and many run ducts through floor belly-pans rather than attics. We carry the equipment to access and photograph those under-floor runs, which standard trunk-and-branch tools cannot reach.
