Lennox Air Duct Cleaning in Southlake, TX | Hollis Air Duct Fort Worth
We provide Air Duct Cleaning - Southlake for Lennox systems, including the Dave Lennox Signature Collection, Elite Series, and Merit Series. What sets our work apart here is straightforward: Southlake’s large custom homes run Lennox zoning and variable-speed equipment hard for most of the year, and that runtime shows up as fine dust packed onto blower blades, sensors, and return plenums. We’re an independent service provider, not a Lennox authorized dealer, which means our recommendations are based on what the system actually needs, not a franchise playbook. Call (682) 255-2572 for a written estimate before any work begins.
Why Southlake Residents Choose Us for Lennox Service
Lennox equipment is everywhere in Southlake, from the sprawling estates in Monticello to the newer builds east of Carroll Avenue. Our techs have spent years working on these systems here, and we recognize the failure patterns before they become complaints: a sluggish upstairs zone, a musty media room, a coil that’s fighting pollen from a long Cedar pollen season. Roy Castellanos, owner at Hollis Air Duct Fort Worth, grew up in East Los Angeles and trained at Los Angeles Trade-Technical College before putting in nearly two decades on Fort Worth area ductwork, including plenty of Lennox zoned setups in Southlake. We bring OEM-spec mastic, foil tape, and flex duct material to every job. We answer the phone when you call. And the price you get in writing is the price you pay after the work is done.
For homeowners comparing options, our Lennox sales & service approach covers the equipment side, while our duct work focuses on the air moving through it.

Common Lennox Air Duct Cleaning Problems We Solve in Southlake
- Variable-speed blower wheels caked with fine dust. Lennox variable-speed air handlers move air more constantly than single-stage units, especially in Southlake homes where thermostats stay set low from May through September. That means the blower wheel becomes a dust magnet. When airflow drops, we see it first on the blower blades.
- Zoning dampers sticking or sending weak air to upstairs suites. Zoned Lennox systems rely on dampers that open and close inside the ductwork. Dust and pet dander settle on damper blades and actuator sensors, causing rooms to feel stuffy even when the AC is running. We clean and test each zone during the job.
- Flexible attic duct runs sagging and trapping remodel dust. Southlake has seen decades of custom home construction and interior renovations. Flex ducts in attics, common on Lennox Signature Collection installs, sag over time and collect a fine layer of drywall dust and insulation fibers. That restricts airflow and pushes dust into living spaces.
- Insulated trunk lines holding humidity and growing mold spores. Lennox Merit systems with insulated trunk lines can absorb moisture during Southlake’s humid summers. When the AC cycles off, that trapped humidity becomes a breeding ground for mold spore buildup inside the ductwork. An annual inspection catches it before it becomes a smell.
- Return air plenums packed with pet dander and pollen. Large zoned Lennox systems pull air through a single, often oversized return plenum. In Southlake households with indoor dogs and cats, that plenum becomes a collection point for dander and spring pollen, reducing efficiency and aggravating allergies for anyone in the family.
Lennox Service in Southlake: What Local Conditions Mean for Your Equipment
Here’s a fact about Southlake you won’t find in a Lennox manual: in the gated communities around Monticello and Estes Park, many homes have dedicated media rooms with full carpet, upholstered walls, and an AC return that barely moves air when the room is empty. That return becomes a dead zone. Dust settles, humidity lingers, and within a season or two the room develops a faint musty odor that persists even after changing the filter. The fix isn’t just brushing the supply lines. We focus on return duct sanitation, cleaning the plenum and return drop, and pressure testing the zone to confirm the system is actually pulling air the way it was designed to. It’s a Southlake problem specifically because of the home layouts here: big floor plans, dedicated theater spaces, and HVAC systems sized for square footage that isn’t always occupied. A generic duct cleaning won’t catch it. We do.
Lennox Models & Products We Service in Southlake
We work on the full Lennox residential lineup in Southlake. That means Dave Lennox Signature Collection systems, Elite Series units, and Merit Series equipment, including the SLO185 oil furnace that shows up in a few of the older custom builds around town. We use OEM-spec mastic, foil tape, and flex duct repair materials that meet or exceed factory specifications. We don’t claim to be an authorized Lennox dealer, and we don’t need to be. When a flex duct is torn beyond repair or a metal trunk shows severe corrosion, we’ll tell you honestly and recommend replacement. When it’s cleaning and targeted sealing that will extend the life of the system, that’s the job we quote and do.

AfterLennox Service Pricing in Southlake
Duct cleaning for a Lennox system in Southlake typically runs between $450 and $900 for a full house, depending on the number of zones, the linear feet of ductwork, and whether we’re also cleaning the blower, coil, and our Dryer Vent Cleaning in Southlake. A zoned Signature Collection system in a 5,000-square-foot home will land at the upper end of that range. A smaller single-zone Merit system will be less. What drives cost is access: attic spaces in Southlake’s larger homes are frequently tight, and flex duct runs can be long. Every estimate is written down before any work starts, and that number does not move once the crew arrives. If a duct fails within a year, the 365-Day Done Right Promise means we return and make it right at no charge. Call (682) 255-2572 for a free estimate that tells you exactly what the job includes.

FAQs – Lennox Air Duct Cleaning in Southlake
Lennox variable-speed blowers and zoned damper systems run air longer and distribute it more evenly than single-stage equipment, which also means they pull in more of the fine drywall dust and insulation fibers that linger after a Southlake remodel. That debris settles on blower blades, damper sensors, and inside flex runs much faster than it would in a simpler system. We recommend a video inspection after any major interior renovation, even if the ducts were cleaned the year before. Call (682) 255-2572 to schedule one.
The most common cause in Southlake’s dedicated media rooms is a return air path that barely moves when the room is unused, allowing dust and humidity to settle in the return drop and plenum. Changing the filter doesn’t fix it because the smell is coming from inside the return duct itself. We address it by cleaning and sanitizing the return side of the system, then pressure testing the zone to confirm proper airflow. Call (682) 255-2572 for an inspection if your media room still smells after a filter change.
Yes. Attic pests are a reality in Southlake’s larger properties, and torn flex duct from rodent or squirrel activity is a genuine problem for Lennox systems, which rely on clean, unobstructed flex runs to deliver conditioned air to far zones. We replace damaged sections with OEM-spec flex material and seal connections with mastic, then verify static pressure before we leave. If the damage is limited, repair is almost always the right call over full replacement. Call (682) 255-2572 for an assessment.
Cleaning your Lennox ductwork can absolutely improve efficiency, especially on zoned systems in Southlake homes where dampers and blower wheels have accumulated dust that forces the system to work harder. A restricted blower or a damper that won’t fully open means longer runtimes and uneven temperatures upstairs. After cleaning the blower wheel, coil, and plenum, most zoned systems deliver measurably better airflow to every room. Call (682) 255-2572 for a free estimate that includes before-and-after documentation.
Plan for a half-day to full-day job, depending on the number of systems and zones. Our crews use negative-air machines from Nikro and rotary brush systems from Rotobrush to clean the supply and return sides, then video inspect the trunk lines before closing everything back up. In a large Southlake home with three or four zones, we typically work system by system so you don’t lose cooling to the entire house at once. Every job includes a written price before work starts and a clean site when we leave.
