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.

Why Hollis Air Duct Cleaning Is DeSoto’s Preferred Air Duct Cleaning Company
We’ve been part of the Garrison Partners family since 2004, and our reputation in DeSoto is built on showing up inside the quoted window and finishing by the book. Homeowners here aren’t looking for the cheapest coupon; they’re looking for the crew that won’t renegotiate at the door. Our technicians are background-checked and uniformed, and we answer calls with a live person 24 hours a day, seven days a week. Roy Castellanos leads this operation, and he set the standard early: written price before work starts, every time, no exceptions.
DeSoto’s housing stock is specific, and that matters. The 1980s – 2000s brick traditional and two-story homes in neighborhoods like Windmill Hill Estates and the areas bordering Duncanville Road have long duct runs in unconditioned attics that newer suburbs simply don’t replicate. We’ve cleaned enough of them to know where the disconnects happen, where the flex duct crushes, and where the late-May humidity spike turns attics into condensation chambers. That local pattern knowledge saves time and prevents misdiagnosis.
Air Duct Cleaning Services in DeSoto
Air Duct Cleaning Services in DeSoto focus on source removal from supply and return ductwork using negative-air machines and rotary brush agitation, followed by HEPA filtration to capture dislodged debris. A typical residential full-system cleaning in DeSoto runs $350 – $550 for single-story homes and $450 – $650 for two-story homes with multiple returns and longer attic runs. Most DeSoto homeowners schedule this service when they notice weak airflow, musty odors at startup, or visible dust cycling from registers. In this market, it’s rarely about new construction debris; it’s about decades of accumulation in mature systems that have never been professionally cleaned.
Residential Duct Cleaning
Our residential work targets the complete supply and return network, from the main trunk to the branch lines feeding each room. In DeSoto’s older two-story homes, we often find the second-floor runs have degraded connections where flex duct meets rigid trunk, or sections that have been crushed by decades of attic traffic. We clean first, then inspect with a camera to locate the real problems.

Commercial Duct Cleaning
DeSoto’s commercial spaces, from the retail corridors along Interstate 35E to the office parks near the city center, require scheduled cleaning that doesn’t disrupt operations. We work after hours and weekends, using the same Rotobrush and Nikro equipment scaled to larger trunk systems, with written pricing agreed before we set up.

HVAC Duct Cleaning in DeSoto
HVAC Duct Cleaning in DeSoto means cleaning the entire air distribution system that connects your furnace and air handler to the rooms you live in, not just vacuuming the vents you can see. For the typical DeSoto home, this service runs $400 – $650 when it includes camera inspection, agitation cleaning of supply and return lines, and sealing of any disconnected or degraded runs we find. Homeowners need this when their system runs constantly but can’t maintain even temperatures, or when they smell mold at the first AC cycle of the season. In DeSoto’s climate, with heavy cooling loads from May through September, a restricted or contaminated duct system forces your HVAC to work harder and deliver less.
Video Inspection Before Work
We run a camera through the trunk and branch lines before we quote the full scope. In DeSoto’s long attic runs, this often reveals crushed flex sections, lint accumulation from degraded dryer connections, or disconnected returns that a surface inspection would miss. The video belongs to you, and it shows exactly why the price is what it is.
Full System Cleaning with Sealing
Cleaning without sealing is half a job in DeSoto. Our crew uses mastic and mechanical fasteners to reconnect separated runs and seal leaks at trunk connections. The sealing is often the real fix, especially in homes where attic humidity has degraded the original tape and connections over twenty-plus years.
Trusted Brands We Service in DeSoto
Our equipment roster includes Rotobrush rotary brush systems for agitation cleaning, Nikro negative-air machines for source removal, and filtration products from Honeywell, Aprilaire, and Guardsman. We don’t use hardware-store vacuums with brush attachments. The negative-air method creates controlled suction throughout your duct system while rotary tools knock debris loose from the duct walls. For DeSoto homeowners, this means we can clean long, multi-return layouts efficiently without spreading contamination into your living space. We stock common fittings and sealing materials locally, so when we find a disconnected run or a degraded boot, we fix it during the same visit rather than scheduling a return trip.
Common Air Duct Cleaning Problems We See in DeSoto Homes
- Disconnected flex duct in attic runs: Decades of attic heat and humidity in DeSoto degrade the original tape and zip-tie connections in 1980s – 2000s homes. A disconnected supply line blows conditioned air into your attic instead of your bedroom, and a disconnected return pulls attic air into your system. Cleaning without reconnecting these leaves you with clean ducts and the same poor airflow.
- Mold growth from late-May humidity spikes: DeSoto’s position in the Blackland Prairie means some of the highest spring allergen loads in North Texas, combined with humidity that turns unconditioned attics into condensation chambers. Second-floor duct runs sweat before homeowners even switch on the AC, creating microbial growth that circulates musty odors at startup.
- Crushed sections in long return runs: Original flex duct in DeSoto’s two-story homes was often routed through tight attic spaces with minimal support. Over years, foot traffic, storage placement, or simply gravity crushes these lines, restricting return airflow and forcing the air handler to overwork. A camera inspection finds what visual checks cannot.
- Lint and debris at dryer-duct connections: Many DeSoto homes have dryer vents that terminate near or share pathways with return ductwork. When those connections degrade, lint enters the return stream and distributes through the house. We identify these crossover points during inspection and recommend separation or proper sealing.
Pricing for Air Duct Cleaning in DeSoto, TX
A full residential air duct cleaning in DeSoto typically costs $350 – $650 depending on system size, accessibility, and whether we find disconnected or damaged ductwork that needs sealing during the same visit. Single-story homes with one or two returns fall at the lower end; two-story brick homes with multiple returns and long attic runs, common in DeSoto’s 1980s – 2000s neighborhoods, fall at the higher end. Commercial systems are quoted individually based on square footage and trunk complexity.
What moves the price: the number of supply and return registers, whether the ductwork is accessible from the attic or requires crawlspace entry, the presence of mold remediation needs, and whether we need to repair or reconnect degraded runs. We do not price per vent, and we do not bait with a low teaser that jumps once we’re inside. The price is written down before any work starts, and it does not move at the door. Call (361) 326-5060 for a free estimate. We’ll ask about your home’s age, layout, and what you’re experiencing, then give you an honest range you can plan around.

FAQs About Air Duct Cleaning in DeSoto
The musty smell comes from mold growth in your second-floor duct runs, which sit in unconditioned attic space where DeSoto’s late-May humidity spike creates condensation before you even turn on the AC. This pattern is specific to DeSoto’s 1980s – 2000s two-story brick homes with original flex duct in vented attics, and it’s why we always inspect with a camera and address moisture pathways, not just surface clean. Call (361) 326-5060 and we’ll check your attic duct conditions.
Cleaning disconnected ducts leaves the real problem untouched: conditioned air blowing into your attic and unconditioned attic air pulled into your returns. In DeSoto’s older homes, decades of attic heat and humidity have degraded original connections, and sealing those runs is what restores airflow and prevents recontamination. We include this assessment in every job, and we quote any sealing work in writing before we start.
Yes, because DeSoto sits in one of the highest spring allergen corridors in North Texas, and decades of accumulated pollen, dust, and microbial growth in original ductwork recirculates through your home every time the system cycles. Cleaning removes the reservoir of accumulated allergens, and sealing prevents new attic contaminants from entering. For homeowners with respiratory sensitivity, the difference in indoor air burden is measurable.
Most 1980s flex duct in DeSoto can be cleaned effectively if the inner liner is intact and connections are resealable. We determine this with a camera inspection before we quote replacement. When the flex is crushed, disconnected, or the liner is degraded by years of attic heat, we recommend replacement of those specific sections, and we price both options in writing so you can decide.
Blowing air through ducts without containment dislodges debris into your living space. Our negative-air method from Nikro machines creates continuous suction at the collection point, so contaminants travel directly into filtered collection rather than settling in your home. HEPA filtration captures particles down to 0.3 microns. In DeSoto’s older homes with decades of accumulation, this controlled approach prevents the very contamination you’re hiring us to remove.
Our tech was already in the area, so we squeezed in a same-week visit to a two-story brick home off Hampton Road, where the homeowner had reported a musty smell upstairs and weak airflow in the back bedrooms. A camera inspection revealed a disconnected flex run and a crushed section feeding the primary return, both original to the house. We set up negative pressure, ran agitation tools through the supply and return ducts, performed source removal with HEPA filtration, and reconnected and sealed the damaged runs. The airflow at the registers came back, and the musty odor cleared – the sealing ended up being the real fix, just as it often is in these older DeSoto systems.
