Lennox Air Duct Cleaning in Dallas, TX | Hollis Air Duct Dallas
Air Duct Cleaning in Dallas for a Lennox system runs $425 to $1,100 for a whole-home system depending on square footage, duct count, and how much repair work the cleaning uncovers. We’re an independent Lennox service provider, not a manufacturer affiliate, and the thing that separates our work in Dallas is that we clean ducts with an eye toward the failure patterns this city creates: rusted under-house metal, sun-baked flex duct, and coils packed with prairie dust. If you own a Lennox system in Dallas, we know where it’s losing air before we even open the blower cabinet. Call (361) 309-6223 for a written estimate.
Why Dallas Residents Choose Us for Lennox Service
Roy Castellanos runs our Dallas crew, and he came up through HVAC and air systems training at Los Angeles Trade-Technical College before the work pulled him east. Since then, he and our techs have worked Lennox systems in neighborhoods across Dallas, from quiet residential streets in Oak Cliff to commercial properties near the Design District. We’ve cleaned enough Lennox flex-duct systems here to know exactly where the Elite and Merit series tend to sag, tear, or separate at the plenum collar. That means we show up already knowing what to look for. For full Lennox sales & service, we keep our focus on the ductwork, coil cleaning, and sealing that keep your equipment breathing.
Every job gets a written price before we touch the system. Background-checked, uniformed technicians do the work, and a live person answers the phone at (361) 309-6223 any hour of the day. The 365-Day Done Right Promise covers every job in writing: if our work fails within a year, we return at no charge. No vague language. That’s how we run every Lennox service across the Dallas service area.

Common Lennox Air Duct Cleaning Problems We Solve in Dallas
- Shattered flex duct in hot attics. Lennox’s insulated flex ducts degrade faster in Dallas attic heat, where summer temperatures regularly climb past 140°F. The inner liner separates, fiberglass blows into supply runs, and your bedrooms get half the airflow the system was designed for. We patch what’s salvageable and replace what isn’t.
- Dust-choked Quantum coils. Lennox high-efficiency evaporator coils, including the Quantum coil, clog with the fine prairie dust and pollen that sweep through Dallas from spring through fall. A coated coil cuts airflow and drives up static pressure. Coil cleaning is part of our standard duct service on Lennox systems.
- Rusted metal supply plenums. In 1970s ranch homes across Dallas, the original Lennox metal plenums rust through from decades of attic humidity swings. Once they breach, cellulose insulation and dust pour into the air stream. We seal or replace plenums while we’re in the attic.
- Variable-speed blower wheels caked with dust. Lennox variable-speed blower motors run constantly during Dallas summers. That’s efficient, but it also means the blower wheel collects a thick dust mat that throws off balance and trips high-static alarms. A dirty blower wheel on a Lennox SL or SLP system is one of the most common calls we get in August.
- Disconnected ducts under pier-and-beam homes. In East Dallas and other pier-and-beam areas, shifting clay soil moves foundations enough to pull duct joints apart under the house. Conditioned air dumps into the crawlspace. We inspect under-house runs and reconnect or replace what’s separated.
Lennox Service in Dallas: What Local Conditions Mean for Your Equipment
Casa View is a neighborhood that teaches you something about Lennox ductwork. The original galvanized metal ducts running under those pier-and-beam homes sit in a humid crawlspace, exposed to the shifting clay soil Dallas is built on. We routinely find 30 to 40 percent of conditioned air escaping through rusted-through or disconnected sections before we even start cleaning. That’s not a national average. It’s a Dallas-specific pattern driven by expansive clay and 1960s construction methods. After a Casa View cleaning job, the question is rarely whether the ducts are clean; it’s how many linear feet of metal need resealing or replacement to make the system worth running. If you own a Lennox system in an older Dallas neighborhood, plan for the possibility that cleaning reveals leaks. We’ll show you photos of every one before recommending what comes next.
Lennox Models & Products We Service in Dallas
We service the full Lennox residential line across Dallas: the Dave Lennox Signature Collection (SL and SLP variable-capacity systems), the Elite Series (XC and XP condensing units with matching air handlers), and the Merit Series (ML and MM basic-efficiency heat pumps and ACs). For parts, we use OEM Lennox filters and coil cleaners when available, because warranty-safe upkeep matters. For duct sealing, we prefer commercial-grade mastic and UL-rated flex duct that hold up better in Dallas attics than original Lennox insulation. We’ll always show you whether a tear can be patched or if a sagging run needs replacement. Repair when possible, replace when it’s costing you efficiency. That’s the standard for Lennox work in Dallas.

AfterLennox Service Pricing in Dallas

FAQs – Lennox Air Duct Cleaning in Dallas
Dallas dust loads are the reason. Lennox publishes general maintenance schedules for a national market, but our city cycles heavy volumes of dusty outdoor air through your ducts from April through October. Prairie dust, pollen, and construction particulates accumulate faster here than in most regions. We recommend a visual inspection every two to three years and cleaning when buildup crosses about an eighth of an inch. Call (361) 309-6223 for an honest assessment.
Often, yes. A dusty blower wheel or a clogged evaporator coil on a Lennox variable-speed system increases static pressure, and the control board reads that as a fault. We see it regularly in Dallas homes where the AC has run hard from May through September. Cleaning the blower wheel and coil frequently clears the code. If the code returns, we’ll look for collapsed or undersized ductwork.
Cleaning alone cannot fix leaks. What it can do is show you where they are. In our experience with East Dallas pier-and-beam homes, decades of clay soil movement has separated or rusted through sections of under-house duct. We’ll clean what’s intact and give you a straight assessment of what needs sealing or replacement. One flat price, written down before work begins.
If the smell comes from condensation or attic dust pulled into the system, cleaning helps. But if the flex duct liner has begun to break down from attic heat, the smell will return until the damaged run is replaced. We’ll inspect the flex while we clean and tell you plainly whether it’s holding up or needs swapping. Call (361) 309-6223 and we’ll take a look.
Watch for rooms that never reach temperature, a sudden jump in your electric bill, or airflow that feels weak at registers far from the air handler. In 1960s Dallas homes, we often find rusted-out metal plenums or collapsed flex in the attic. A manual inspection with a camera tells you what’s actually happening. We’ll show you photos and write up the price before any repair work starts.

Our crew worked a 1978 brick ranch in Lake Highlands where a Lennox Elite XC21 had been choking on attic insulation fibers. The return flex had split at the plenum collar, and the blower wheel was caked with a half-inch of gray dust from months of pulling unfiltered attic air. We patched the flex, sealed every supply boot with mastic, and did a full evaporator coil clean. Static pressure dropped into normal range and the homeowner felt airflow in the back bedrooms for the first time in two summers.
