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 Air Duct Cleaning Across Longwood
Most homes in Longwood need full-system air duct cleaning every 4-6 years, with costs running $380-$620 for a typical 1,600-2,000 square foot home with attic flex-duct runs. We’re Kestrel Air Duct Cleaning, and our crews work Longwood neighborhoods from Sweetwater Oaks to Sabal Point to Longwood Hills regularly. Dispatch and scheduling are coordinated from our Miami office, but the technicians who arrive at your door know this city’s housing stock: the 1980s slab-on-grade builds, the attic-only duct routing, the fiberglass duct board that’s now hitting its failure age. Call (469) 972-3151 and you’ll reach a live person, any time of day. We’ll give you a written price before a single vent is touched.
Why Kestrel Air Duct Cleaning Is Longwood’s Preferred Air Duct Cleaning Company
We’ve built our reputation in Longwood by being the company that tells homeowners the truth about whether their ducts can actually be cleaned or need replacement. That honesty matters here more than in newer suburbs. Our Air Duct Cleaning team carries written pricing on every visit under the Kingswell Guarantee, which we’ve applied since 2004. Longwood customers know our arrival windows mean something, and our 365-Day Done Right Promise means we come back at no charge if the work falls short.
Our technicians are background-checked and uniformed, and they show up with Rotobrush rotary brush systems, Nikro negative-pressure units, and Abatement Technologies HEPA filtration - not box-store shop vacs. The Kingswell Way governs every visit: say the price, show up in the window we gave, leave the place cleaner, put the guarantee in writing, come back if it fails. That’s the standard Dale Whitmore set from the start, and it’s the standard our Longwood customers hold us to.
Air Duct Cleaning Services in Longwood
Air Duct Cleaning Services in Longwood cover the complete removal of dust, debris, and biological growth from your home’s duct network, with special attention to the flex-duct and duct-board systems that dominate local housing. A typical residential cleaning in Longwood runs $380-$620 depending on system size, accessibility, and whether video inspection reveals delaminated duct board that needs section replacement rather than cleaning alone. Most Longwood homes need this service every 4-6 years, though homes with pets, recent renovations, or visible mold around vents should schedule sooner.
Full System Cleaning with Source Removal
We don’t blow dust around. Our Rotobrush rotary brush agitation dislodges debris at the duct wall while Nikro negative-air extraction pulls it out of your home entirely. Abatement Technologies HEPA filtration captures loosened particles so they don’t resettle in your living space. This matters in Longwood, where A/C runs 10-11 months a year and any debris left behind recirculates immediately.

Video Inspection Before and After
We run camera inspection down every accessible run so you see what we see: the dust buildup, the torn flex liner, the delaminating duct board. After cleaning, we run it again. The before-and-after footage goes to you, not just our files. In a market full of bait-and-switch pricing, visual proof of completed work is how we back up our written guarantee.

HVAC Duct Cleaning in Longwood
HVAC Duct Cleaning in Longwood means addressing the entire air distribution system - supply ducts, return ducts, the air handler cabinet, and the plenum connections - not just the vents you can see from the hallway. Because Longwood’s dominant housing stock runs horizontal flex duct through unventilated attics that hit 140°F+ in summer, we regularly find heat-degraded material, sagging joints, and biological growth that standard vent-cleaning misses. A complete HVAC duct cleaning for a typical Longwood home runs $450-$720 when the air handler and return plenum are included.
Return Plenum and Air Handler Cleaning
The return side pulls air from your home back to the air handler, and it’s where humidity and biological growth concentrate in Longwood’s climate. We clean the return plenum, the blower assembly, and the evaporator coil access area. Skip this and you’ve cleaned half the system while leaving the contamination source intact.
Supply Duct Sanitization
After mechanical cleaning, we apply EPA-registered sanitizers to supply runs where mold or bacterial growth has been active. This isn’t a fragrance mask - it’s a targeted treatment for the biological colonization that thrives in Longwood’s sustained 80-90% summer humidity.
Trusted Brands We Service in Longwood
We clean duct systems connected to every major HVAC brand installed in Longwood homes, and we stock Honeywell, Aprilaire, and Guardsman filtration products for homeowners who want to maintain cleaner air between service visits. If your system needs upgraded filtration after cleaning - common in homes where duct board delamination has been shedding particles for years - we can install Aprilaire media air cleaners or Guardsman UV treatments during the same visit. Our trucks carry the common fittings and transition pieces needed for 1980s-era systems, so we’re not ordering parts and making you wait while your A/C is down.
Common Air Duct Cleaning Problems We See in Longwood Homes
- Delaminated fiberglass duct board in Sabal Point and Sweetwater Oaks. After 35+ years in 140°F+ attic heat, the fiberglass duct board installed in these subdivisions sheds glass fibers directly into the living-space airstream. Cleaning removes the loose debris but cannot restore structural integrity to failed board. We replace failed sections with R-8 flex duct and sealed plenum connections.
- Shared dryer exhaust stacks in multi-family buildings. Condo and apartment buildings in Longwood’s denser core route dryer exhaust through a single vertical column. Cleaning only the unit-level lint trap leaves the shared column loaded with combustible lint, creating fire risk that unit owners downstream don’t realize they share.
- Equipment access failures at restricted properties. Multi-family properties with no curb access force less thorough contractors to park a hundred feet from the service entry, leave the negative-pressure machine in the truck, and “clean” with a shop vac. Source removal never happens. Dust gets redistributed, not extracted.
- Skipped return plenums in “quick tune-up” cleanings. Property managers scheduling around tenant move-outs get sold on surface-level cleaning that skips the air handler and return plenum. The 35-year-old flex runs stay contaminated, and new tenants report allergy symptoms within a month.
Pricing for Air Duct Cleaning in Longwood, FL
Here’s what air duct cleaning actually costs in Longwood’s market. A standard residential full-system cleaning for a typical 1,400-2,200 sq ft home with attic flex-duct runs: $380-$620. Add air handler and evaporator coil access cleaning: $450-$720 total. Commercial systems and multi-zone residential setups run higher based on duct complexity and access. Section replacement of failed flex duct or delaminated duct board is priced separately, with written line items before work begins.
What moves you within these ranges? System size, number of returns and supplies, attic accessibility, and whether video inspection reveals material failure that needs repair before cleaning is worthwhile. We don’t quote per-vent pricing - that’s the bait-and-switch model. One flat price per system, agreed in writing before we touch a vent. Estimates are free. Call (469) 972-3151.

FAQs About Air Duct Cleaning in Longwood
Your fiberglass duct board is likely delaminating from decades of 140°F+ attic heat, shedding glass fibers into the airstream when the blower runs. Cleaning removes loose debris but cannot restore failed board. We replace delaminated sections with R-8 flex duct and sealed plenum connections, then verify with post-repair camera inspection. Call (469) 972-3151 for a free evaluation.
Yes, we clean shared dryer exhaust columns in multi-family buildings, which unit-level lint trap cleaning alone cannot address. The shared stack accumulates combustible lint across multiple units, creating fire risk that individual owners may not recognize. We access the column from rooftop or utility-room termination points and extract lint with negative-pressure equipment. Call (469) 972-3151 to schedule building-wide service.
Yes, this describes most Longwood homes we work on. Slab-on-grade construction with attic-only flex duct is our standard operating environment here. Our equipment is designed for attic access, and our technicians are trained to navigate tight spaces, identify heat-degraded flex, and work around the insulation and truss configurations common to 1978-1992 construction.
Cleaning is sufficient when ducts are structurally intact with surface contamination only. Replacement is necessary when flex duct inner liners are torn, duct board is delaminated, or sagging joints have separated. In Longwood’s 35-45-year-old housing stock, we find both conditions regularly. Our video inspection shows you which applies to your system before you commit to either approach. Call (469) 972-3151 for an honest assessment.
Longwood’s sustained 80-90% summer humidity with no coastal moderation creates year-round conditions for mold and bacterial growth in duct interiors, especially around poorly sealed returns. Cleaning removes existing biological load, but without addressing humidity sources and return leakage, regrowth accelerates. We identify seal failures during inspection and can recommend Aprilaire dehumidification or upgraded filtration to extend cleaning results. Call (469) 972-3151 for system-specific recommendations.
In Sabal Point we opened a return chase on a 1983 slab-on-grade home and found the duct board liner blown apart, shedding glass fibers through every supply the homeowner had been breathing for years; we ran camera inspection down the flex runs, pulled the delaminated board under negative pressure with HEPA filtration, replaced the failed sections with R-8 flex, and sealed the plenum at the air handler, and the blower motor stopped icing up on its own.
Ready to find out whether your Longwood ducts need cleaning or honest replacement talk? Call (469) 972-3151. A live person answers 24/7. We’ll give you a written estimate before any work begins, and every job carries our 365-Day Done Right Promise in writing.
