Why Fort Worth Homeowners Choose Lennox Air Duct Cleaning
Hollis Air Duct Fort Worth provides independent Air Duct Cleaning services, evaporator coil cleaning, video inspection, and duct sealing across Fort Worth, TX. Our techs work on Lennox systems daily, from older G-series furnaces to newer Dave Lennox Signature Collection air handlers, and we know exactly how these units collect and spread debris through Texas heat and humidity. We are not affiliated with or authorized by Lennox, which means we answer to you, not a manufacturer’s service quota. Call (682) 255-2572 for a written quote before any work starts.
Fort Worth homeowners run their Lennox air conditioners hard from May through September. That heavy runtime pulls oak pollen, ragweed, West Texas dust, and humidity into the duct system, and Lennox high-efficiency coils are tighter than older designs, so they trap more of that debris. Our experience with these specific systems is the difference between a surface cleaning and a job that actually restores airflow and cuts dust levels inside your home. Call (682) 255-2572 for a free estimate.
Why Trust Hollis Air Duct Fort Worth for Your Lennox Air Duct Cleaning?
Roy Castellanos, owner at Hollis Air Duct Fort Worth, learned HVAC fundamentals at Los Angeles Trade-Technical College before deciding the trade was worth doing right or not at all. He has spent the better part of two decades cleaning and inspecting duct systems across Fort Worth, including older brick ranch homes near the Stockyards where decades of dust and debris pack into supply trunks like insulation. His standard is simple: show up, do the work, and leave the system in measurably better shape than we found it.
Our technicians are background-checked and uniformed. They arrive inside the quoted window, write the price down before touching anything, and complete the job under The Garrison Standard: price in writing, work by the book, site left clean. Every Lennox job is covered by the 365-Day Done Right Promise. If the work fails within a year, we return and make it right at no charge, including a free second visit. That is not a verbal assurance; it is written on every job we do in Fort Worth.
We also use professional-grade equipment from Rotobrush, Nikro, Abatement Technologies, and filtration brands including Honeywell, Aprilaire, and Guardsman. The negative-air method we run on most Lennox systems pulls dust and debris out of the ductwork rather than blowing it around. The rotary brush system scrubs the interior walls. These are the same tools commercial crews use, and we explain what each one does in plain terms before we start.

Common Lennox Air Duct Cleaning Problems We Fix in Fort Worth
- Tightly spaced evaporator coils on high-efficiency Lennox models. The Dave Lennox Signature Collection XC25 and Elite Series EL18XCV use densely packed coils to hit high SEER ratings. That tight spacing traps fine dust and pet hair faster than older coil designs. In a Fort Worth summer with the AC running 12-plus hours a day, that debris restricts airflow and causes coil freeze-ups. We clean the coil with the right tools, not a pressure washer, and verify airflow with a video inspection before we leave.
- Flex duct connections loosening on variable-speed Lennox systems. Variable-speed air handlers like the SLP98V and EL296V cycle airflow more aggressively than single-speed units. Over time, flex duct connections at the plenum and branch runs loosen, pulling attic insulation, dust, and sometimes pest debris into the air stream. We inspect every connection, re-secure loose collars, and seal gaps with duct sealing mastic. That is not a band-aid; it is the proper fix.
- Healthy Climate media filters clogging faster in Fort Worth dust conditions. Lennox Healthy Climate filters like the HC16 and HCC20 are more efficient than standard one-inch filters. In Fort Worth, where spring brings oak and ragweed pollen and West Texas dust storms blow through, those media filters load up fast. When they clog, the system runs imbalanced and pushes debris unevenly through the ducts. We check filter condition and recommend replacement intervals based on actual runtime, not a generic 90-day rule.
- Blower wheel buildup on older Lennox furnaces. G-series furnaces and early Merit Series ML180 and ML193 units are workhorses, but their blower wheels collect a hardened layer of lint and dust over the years. That buildup reduces airflow and makes the system noisy, especially when the AC kicks on. We pulled apart a Lennox SLP98V in a Fort Worth attic recently and found the blower wheel packed in pet hair and years of fine dust. Return air was nearly choked off. We cleaned the blower assembly, video-inspected the entire duct run, and sealed leaking flex connections with mastic. Airflow jumped back to spec and the homeowner’s electric bill dropped noticeably.
- Asbestos-wrapped metal ducts in older Fort Worth ranch homes. The 1950s through 1970s brick ranch homes across Fort Worth, especially in Wedgwood and East Fort Worth, often have original metal ducts wrapped in asbestos-containing insulation. Improper cleaning releases fibers. The Garrison Code requires our techs to contain and handle these ducts carefully, using negative-air containment where needed. Clean ducts don’t advertise themselves, but dirty ones will, and in these older homes the material wrapped around the ducts demands as much attention as the dust inside them.
Lennox Parts & Our Repair-vs-Replace Approach
We use OEM Lennox filters and replacement parts whenever they are available. For discontinued older models, like early G-series furnaces or the first-generation Merit Series air handlers, we source quality aftermarket components that meet or exceed the original specifications. We do not install cheap knockoff parts to pad a margin.
Our repair-vs-replace stance is straightforward. We recommend replacement only when ductwork is collapsed, severely rusted, or so degraded that it cannot be cleaned to a healthy standard. We do not sell new equipment to hit a sales target. If the duct system can be cleaned, sealed, and put back into service reliably, that is what we recommend. The price is written before we start, and it does not move at the door. Call (682) 255-2572 to talk through what your Lennox system actually needs.
Our Lennox Service Process – Step by Step
- 1
Diagnosis. We start with a visual inspection of the air handler, blower compartment, coil, and accessible duct runs. On Lennox systems, we check the specific failure points: coil spacing on high-efficiency models, flex duct connections on variable-speed units, filter condition on Healthy Climate setups, and blower wheel buildup on older furnaces. We use video inspection to see inside ducts we cannot physically reach.
- 2
Repair or cleaning. We quote a written price based on what the diagnosis shows. If the coil needs cleaning, we clean it with equipment designed for Lennox coil geometry. If flex connections are loose, we re-secure and seal them with mastic. If the ducts need cleaning, we run the negative-air system with rotary brush agitation where the duct material allows it. Older metal ducts with asbestos wrap get containment protocols, not aggressive brushing.
- 3
Test. After the work, we measure airflow at the registers and verify the system is moving air the way a Lennox unit of your model should. We check static pressure on variable-speed systems and confirm the blower ramps up and down without noise or vibration.
- 4
Warranty. Every job is covered in writing by the 365-Day Done Right Promise. If something fails within a year, we come back at no charge. That includes a free second visit. You get this in writing on the job paperwork, not as a verbal promise.

FAQs – Lennox Air Duct Cleaning Service in Fort Worth
No. We are an independent Lennox service provider. We are not affiliated with or authorized by Lennox, and we do not claim factory training or manufacturer endorsement. What we do have is daily hands-on experience with Lennox systems in Fort Worth homes, from old G-series furnaces to current Dave Lennox Signature Collection equipment. That experience is what earns our reputation, not a manufacturer badge.
We use OEM Lennox filters and replacement parts when available. For discontinued older Lennox models, we source quality aftermarket components that meet or exceed original specifications. We will tell you which one applies to your system before you pay for anything. The part choice is written into the quote.
A standard Mansfield Lennox service duct cleaning on a typical Fort Worth single-family home takes four to eight hours, depending on the number of returns, the duct layout, and the level of buildup. Older ranch homes with asbestos-wrapped metal ducts take longer because of containment protocols. We will give you a realistic time window when we quote the job, and we arrive inside it. Call (682) 255-2572 for a free estimate.
We cover the Dave Lennox Signature Collection including the SLP98V, SLP99V, and XC25; the Elite Series EL296V, EL18XCV, and EL280; the Merit Series ML180, ML193, and ML14XC1; and the Healthy Climate line, including HCWB3 humidifiers, HCC20 media cabinets, and HC16 media filters. We also service older G-series Lennox furnaces still running in many Fort Worth homes.
No. Air duct cleaning, coil cleaning, and duct sealing are maintenance services, not modifications to the HVAC equipment itself. Our work does not alter the warranty registration on your Lennox furnace or air conditioner. We do not cut into equipment or bypass any safety or control components. Your Lennox equipment warranty remains the manufacturer’s responsibility; our work is covered separately by the 365-Day Done Right Promise.
Lennox air duct cleaning in Fort Worth typically runs between $450 and $1,200 depending on home size, the number of returns, the duct material, and whether coil cleaning or duct sealing is included. Older ranch homes with asbestos-wrapped ducts cost more because of containment requirements. The price is written before we touch anything, and it does not move at the door. Call (682) 255-2572 for an exact quote – estimates are free.
Yes. Variable-speed Lennox systems like the SLP98V and EL296V move air differently than single-speed units. We check static pressure and flex duct connections before we clean, because aggressive negative-air cleaning can pull loose connections further apart or damage older flex duct. The cleaning itself uses controlled negative-air with rotary brush agitation only where the duct material can handle it. In newer Fort Worth homes with flexible ductwork, we dial the aggression back. It is not a one-setting-fits-all process.
Yes. A dirty evaporator coil reduces airflow and causes the system to run longer and harder. That pulls more dust through the ducts and can cause humidity problems that make dust stick to surfaces. In Fort Worth, where the AC runs heavily from May through September, a dirty coil on a Lennox XC25 or EL18XCV compounds the dust load. Cleaning the coil is often the missing step after a duct cleaning. We include coil inspection as part of our Lennox service process.
With a Healthy Climate HC16 or HCC20 filter in place, you can usually go three to five years between duct cleanings in Fort Worth, assuming the filter is changed on schedule and the duct system is sealed properly. Without a media filter, most Fort Worth homes need air duct cleaning every two to three years. The filter condition matters more than the calendar. We check it on every visit and tell you what we see.
If the duct system was not sealed during the furnace replacement, construction dust, drywall debris, and insulation can sit in the ducts and blow through the new system from day one. We recommend a video inspection and cleaning before you put a new Lennox furnace into service, especially in older Fort Worth homes where the existing ducts have never been touched. It is far cheaper to clean the ducts before the new furnace starts pulling debris through its heat exchanger and blower.
Often yes. A rumbling sound when the AC starts usually points to blower wheel buildup, loose flex duct connections, or a return duct that is undersized for the Lennox unit it serves. Older Lennox furnaces are prone to hardened lint and dust on the blower wheel blades, which throws the wheel out of balance. We diagnose the cause before recommending any work. Call (682) 255-2572 to schedule a diagnosis in Fort Worth.
