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.

We’re familiar with the specific challenges Lake Mary homeowners face. This city developed almost entirely as a master-planned suburb during the 1980s and 1990s, which means the vast majority of its residential housing stock is now 25-40 years old and still contains original flexible ductwork. That aging flex duct sags, delaminates, and traps mold in a region where the AC runs 10-11 months a year. This single generational wave of construction has created a city-wide replacement and deep-cleaning cycle that is hitting simultaneously, making Lake Mary a uniquely high-demand market right now. We built our service around that reality.
Why Kestrel Air Duct Cleaning Is Lake Mary’s Preferred Air Duct Cleaning Company
We’ve earned our reputation in Lake Mary by showing up in the window we promised and putting the price in writing before we touch a single vent. The Kingswell Guarantee, which governs every job we perform, was established in 2004 and hasn’t changed: written price first, defined arrival window, clean job site, and a written guarantee with a free return visit if the work fails within the guarantee period.
Our technicians are background-checked, uniformed, and trained on professional-grade equipment: Rotobrush rotary brush systems for dislodging debris at the duct wall, Nikro negative-pressure units for pulling contaminants out, and Abatement Technologies HEPA filtration to keep loosened particles out of your living space during cleaning. We don’t use box-store shop vacs.
Calls are answered by a live person, 24/7. Not a voicemail queue. Not an automated system. A real conversation any time of day.
Our 365-Day Done Right Promise is documented in writing on every single job. If the work falls short within that period, we return and make it right at no charge. No discretion, no negotiation, no disappearance after the invoice is paid.
Air Duct Inspection in Lake Mary
Air Duct Inspection in Lake Mary is the critical first step for any homeowner whose house was built during the city’s 1980s-1990s construction boom. A typical inspection for a Lake Mary home runs $150-$250 and includes a full video assessment of the supply and return ductwork, plenum connections, and flex duct condition. We use push cameras to document what homeowners cannot see: collapsed sections hidden above the drywall, disconnected plenums pumping conditioned air into attic insulation, and mold growth on delaminated duct liners that still “work” because the blower compensates.
What the Camera Reveals
Our video inspection records the interior condition of every accessible duct segment. In Lake Mary’s humid microclimate, we regularly find biofilm growth on flex duct interiors that stay damp from near-continuous AC operation. The footage goes to you, not just to us. You see what we see.
When to Schedule
Book an inspection if you’ve noticed dust resettling within hours of cleaning, uneven cooling between rooms, or a musty odor when the system cycles. These symptoms often trace back to plenum disconnections or collapsed flex duct in the original 1990s-era subdivisions off Rinehart Road and around Lake Mary Boulevard.
Residential Air Duct Cleaning in Lake Mary
Residential Air Duct Cleaning in Lake Mary addresses a housing stock unlike neighboring cities: nearly every home was built in the same two-decade window with the same fiberglass-lined flexible duct systems, and those systems are now failing simultaneously. A complete residential cleaning for a typical Lake Mary home runs $350-$650 depending on system size, accessibility, and whether antimicrobial treatment is indicated. We perform source removal with rotary brush agitation under negative-air extraction, followed by HEPA filtration and, when needed, antimicrobial treatment of the supply and return ducts.
The Full System Approach
We clean supply ducts, return ducts, trunk lines, and plenums as an integrated system. Partial cleaning recirculates contaminants from dirty sections into cleaned ones. Our Nikro negative-pressure units maintain continuous suction during brush agitation so dislodged debris exits the ductwork rather than settling in your home.
Post-Cleaning Verification
We provide before-and-after photos of your own ducts, not stock images. The 365-Day Done Right Promise covers the work in writing. If dust, odor, or airflow issues persist, we return at no charge.
Trusted Brands We Service in Lake Mary

Replacement filters, UV air purifiers, and whole-house humidification controls are available with same-day installation in most Lake Mary neighborhoods because we keep inventory matched to the systems common in local homes. No waiting on a parts order from Orlando.
Common Air Duct Cleaning Problems We See in Lake Mary Homes
- Original flex duct collapsing at the plenum. We were called to a 1996 home off Rinehart Road where the homeowner complained of fine dust settling on furniture within hours of cleaning, even though the AC still blew cold air. A camera inspection revealed the original flex duct had collapsed and disconnected at the plenum, so the system had been pushing conditioned air through attic insulation and distributing fiberglass particles and mold spores throughout the house for years.
- Construction debris in new builds. Builders hand over new homes with drywall dust, sawdust, and construction debris still in the supply and return ducts because they never ran a proper source-removal cleaning before closing. New owners often assume a new house has clean ducts. It usually doesn’t.
- Mold and biofilm from persistent humidity. Lake Mary is surrounded by and named for its network of lakes and wetlands in Seminole County, which elevates ambient humidity compared to drier inland areas. This accelerates mold and biofilm growth inside flex duct interiors that already stay damp from near-continuous AC operation. Post-cleaning antimicrobial treatment is not optional here but a near-standard necessity.
- Fiberglass liner delamination. The interior liner of 1980s-1990s flex duct breaks down over time, releasing fiberglass particles into the airstream. Homeowners notice this as a fine, persistent dust that doesn’t respond to normal cleaning routines.
Pricing for Air Duct Cleaning in Lake Mary, FL
Most complete residential duct cleanings in Lake Mary run $350-$650 for a full system. Commercial systems along the I-4 corridor, including the office campuses near Heathrow and Markham Woods, are priced by system size and typically start at $800. Video inspection runs $150-$250 and is credited toward cleaning if you proceed.
What moves the price: square footage and vent count, accessibility of the main trunk lines, whether the home has original flex duct requiring more careful handling, and whether antimicrobial treatment is indicated due to mold or biofilm. We do not price per vent. We do not bait with a low coupon and revise at the door. The written price in your hands before we start is the price you pay. That’s the Kingswell Guarantee, and it has been since 2004.

FAQs About Air Duct Cleaning in Lake Mary
The warning signs are uneven cooling between rooms, a musty odor when the AC cycles, fine dust that resettles within hours of surface cleaning, and higher-than-expected energy bills as the blower motor compensates for collapsed or disconnected sections. A video inspection confirms the condition. Call (469) 972-3151 to schedule one.
Builders rarely perform source-removal cleaning after construction, so drywall dust, sawdust, and debris remain in the supply and return ducts at handover. The AC then circulates this material through your home for months. A pre-occupancy cleaning removes construction residue before you move in. Call (469) 972-3151 for an estimate on new-construction cleaning.
Yes. Lake Mary’s lake-and-wetland geography elevates ambient humidity compared to drier inland areas, and the near-continuous AC operation keeps flex duct interiors damp. This combination creates conditions where mold and biofilm regrow quickly after cleaning if not treated. We evaluate every Lake Mary job for antimicrobial need and document the recommendation in writing.
A proper cleaning involves rotary brush agitation with Rotobrush equipment to dislodge debris at the duct wall, negative-air extraction with Nikro units to pull contaminants out of the system, and Abatement Technologies HEPA filtration to capture loosened particles before they enter your living space. We provide before-and-after photos of your specific ducts and a written 365-Day Done Right Promise. Call (469) 972-3151 for details.
Cleaning restores airflow and removes contaminants, but it cannot reverse structural failure: collapsed sections, disconnected plenums, or delaminated fiberglass liner require replacement. Our inspection identifies which condition applies to your system. We clean what can be cleaned and document what needs replacement so you can plan accordingly. Call (469) 972-3151 to schedule an inspection.
