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 Flower Mound
Air duct cleaning in Flower Mound, TX typically costs $350 – $650 for a whole-home system and is scheduled by appointment with a written price locked in before work begins. Hollis Air Duct Cleaning dispatches crews from our Dallas-Fort Worth office to serve Flower Mound homes directly, and we know the territory: the sprawling master-planned communities, the 3,000-square-foot builds with multiple HVAC zones, and the attic conditions that define what actually goes wrong up there. Call (361) 326-5060 for a free estimate.
We’ve worked in Flower Mound long enough to know that a standard duct cleaning often isn’t the full story. The homes here, especially in neighborhoods developed from the 1980s through the 2000s, were built with long flex-duct runs through unconditioned attics that hit 140°F or higher in July and August. That heat degrades duct mastic, collapses flexible trunk lines, and separates connections at the plenum. Our Air Duct Cleaning team is trained to find those failures before we quote a price, because cleaning a disconnected duct run is a waste of your money and ours.
Why Hollis Air Duct Cleaning Is Flower Mound’s Preferred Air Duct Cleaning Company
Flower Mound homeowners call us because we show up inside the window, price the job in writing before touching equipment, and leave the site clean. That’s The Garrison Standard, and it applies to every Hollis location, including ours serving Flower Mound.
Our technicians are background-checked and uniformed. You know who’s arriving before they pull into your driveway. Phones are answered by a live person 24 hours a day, 7 days a week. No voicemail loops, no callback queues, no waiting until Monday morning to schedule.
Every job carries the 365-Day Done Right Promise in writing. If our repair or sealing work fails within a year, we return and make it right at no charge, including a free second visit. We don’t negotiate this after the fact; it’s on the paperwork before we start.
Roy Castellanos leads our operation, and that accountability matters in a market where too many duct-cleaning outfits compete on a low teaser price that balloons once the van is in your cul-de-sac. We don’t do that. The price is the price.
Ductwork Cleaning in Flower Mound
Ductwork Cleaning in Flower Mound means removing accumulated dust, debris, and biological buildup from the supply and return ducts that move conditioned air through your home. In a typical Flower Mound residence with 2 – 3 HVAC zones and 3,000 – 6,000 square feet, this service runs $350 – $550 per system, with whole-home packages for multiple zones ranging $650 – $950. Homes in Bridlewood, Wellington, and The Lakes often need multi-system service due to their size and zoning configuration.
We use a negative-air method: a Nikro portable HEPA vacuum attaches to your trunk line while rotary brushes from Rotobrush agitate debris inside the ducts. This pulls contaminants out rather than pushing them deeper into the system. For Flower Mound’s older flex-duct installations, we adjust brush tension to avoid damaging fragile R-4 or R-6 material that’s already heat-stressed.
What We Find in Flower Mound Attics
Most Flower Mound homes we enter have blown-in insulation 12 – 18 inches deep. That depth hides crushed or separated duct runs that no surface inspection will catch. Our techs probe carefully, and when we suspect a hidden failure, we recommend a camera inspection before quoting cleaning alone.
Supply and Return Duct Cleaning
Supply ducts push cooled air to your rooms; returns pull air back to the handler. Both sides need attention. In Flower Mound’s work-from-home households, these systems run continuously, accelerating buildup. We clean both, then verify airflow balance room-to-room.
Air Duct Inspection in Flower Mound
Air Duct Inspection in Flower Mound is the diagnostic step that determines whether cleaning will actually solve your problem or whether you’re treating symptoms while the real failure hides in the attic. A standalone inspection runs $150 – $250; when bundled with cleaning, we often waive or reduce this fee. Given what we find in local homes, we recommend an inspection first for any property built before 2005.
We pulled into a Bridlewood home where a back bedroom never cooled; our tech went up into the blown-in insulation and found a 1990s flex trunk crushed flat behind the air handler, with the plenum connection separated. After a camera inspection, we re-sealed and reconnected the run using mastic and new flex, then cleaned the supply and return ducts under negative pressure. The homeowner’s “dirty ducts” were actually disconnected ducts. Cleaning alone would have left the problem untouched and the bedroom still hot.
Camera Inspection for Hidden Failures
Our video inspection system feeds a lighted camera through your trunk lines and into branch ducts. In Flower Mound’s deep-attic homes, this reveals separations, collapses, and insulation infiltration that a flashlight check misses. We record what we find and show you before quoting any repair.
Pressure Testing and Airflow Measurement
After visual and camera inspection, we measure static pressure and airflow at each register. This quantifies what you’re feeling: hot rooms, weak airflow, or a system that runs constantly without reaching setpoint. Numbers don’t guess.
Trusted Brands We Service in Flower Mound
Hollis crews in Flower Mound carry professional-grade equipment from Rotobrush, Nikro, and Abatement Technologies, plus filtration products from Honeywell, Aprilaire, and Guardsman. We stock common flex-duct sizes, mastic, and connection hardware locally so we’re not waiting on a parts run while your attic hangs open. Rotobrush rotary systems handle the agitation work inside your ducts; Nikro negative-air machines create the suction that pulls debris into HEPA filtration. For homes in The Lakes or Wellington with newer HVAC installations, we also source Honeywell and Aprilaire media filters and Guardsman UV components when upgrade makes sense.
Common Air Duct Cleaning Problems We See in Flower Mound Homes
- Collapsed flex duct in 140°F attics. Original R-4 and R-6 flex from the 1990s softens and collapses under sustained heat, especially where it sags between supports. The duct becomes a pinched straw. Air can’t move. We find this weekly in Bridlewood and Wellington.
- Separated plenum connections. Duct mastic dries and cracks after 20+ summers in a Flower Mound attic. The connection between metal plenum and flex trunk loosens, and conditioned air dumps straight into your insulation. Your bill climbs. Your rooms stay warm.
- Pressure imbalances from multi-zone systems. With 2 – 3 HVAC zones and long branching runs, a single failure in Zone 2 can backpressure Zone 1. Homeowners call us for “upstairs not cooling” and we find a crushed return in the attic above the garage.
- Biofilm and mildew in humid ductwork. Flower Mound’s humid subtropical climate means summer dew points in the 70s. Any duct leak that pulls attic air into the system also pulls moisture. Combine that with 24/7 runtime from work-from-home occupancy, and you’ve got conditions for biological growth that standard filters won’t catch.
Pricing for Air Duct Cleaning in Flower Mound, TX
Here’s what air duct cleaning costs in Flower Mound’s market, based on the home profiles we actually service:
- Single-system duct cleaning (typical 1,500 – 2,500 sq ft home): $350 – $450

No per-vent add-ons, no “surprise contamination” upsells. Factors that move you within these ranges: number of HVAC systems, accessibility of attic runs, whether we find disconnected duct that needs reconnection before cleaning can be effective, and whether you want filtration upgrades while we’re in the system.

FAQs About Air Duct Cleaning in Flower Mound
The hot rooms are usually caused by disconnected, crushed, or separated duct runs in the attic, not dirty ducts. In Flower Mound’s Bridlewood and Wellington neighborhoods, we regularly find 1990s flex duct that’s collapsed behind the air handler or separated at the plenum, dumping conditioned air into your insulation. Cleaning won’t fix a duct that’s physically blocked or open to the attic. Call (361) 326-5060 and we’ll inspect before quoting any work.
Every 3 – 5 years for typical households, but every 2 – 3 years if your systems run continuously due to work-from-home occupancy or if you have pets. Flower Mound’s combination of 24/7 runtime, humid summers, and original builder-grade flex duct means debris and biological buildup accelerates faster than in homes with newer, sealed ductwork. Call (361) 326-5060 to schedule an inspection and we’ll tell you whether you’re due.
Our technician enters the attic, probes through the insulation along known duct runs, and uses a lighted camera to examine trunk lines, plenum connections, and branch ducts that are visually inaccessible. In Flower Mound’s deep-insulation attics, this takes 45 – 90 minutes and often reveals crushed or separated flex duct that a surface check would miss. We record video and review findings with you before any repair or cleaning begins.
Yes. We regularly inspect, reconnect, seal, and replace original R-4 and R-6 flex duct in these neighborhoods. The material is typically 25 – 35 years old and heat-degraded. We assess whether reconnection and sealing with mastic will restore function or whether replacement is the more durable fix, then quote accordingly. Call (361) 326-5060 to schedule.
Because the dominant failure mode in Flower Mound’s 1980s – 2010s housing stock is not contamination buildup but physical duct damage: collapsed, separated, or leaking runs that lose 20 – 40% of conditioned air to the attic. Sealing with mastic and reconnecting trunk lines restores pressure, airflow, and efficiency. Cleaning a leaking system is like washing a car with a hole in the radiator. We inspect first so we don’t sell you what you don’t need.
