We’re not a Lennox dealer or authorized representative. We’re an independent Irving-based duct cleaning crew that specializes in Lennox systems, having cleaned and sealed ductwork on thousands of Air Duct Cleaning services across DFW. Our techs know Lennox-specific ducting and coil configurations from daily field work in neighborhoods like Valley Ranch, Las Colinas, and the older ranch-home corridors of North Irving, not from a distributor training badge. That independence matters because it means we repair what’s actually broken rather than selling what a franchise manual says to push.

Irving’s housing stock creates specific Lennox challenges you won’t find in every suburb. The 1950s-1970s ranch homes in North and West Irving frequently run original sheet-metal ductwork or early-generation flex duct paired with newer Lennox air handlers retrofitted during the 2015-2025 renovation wave. The 1980s-1990s townhome clusters around Las Colinas compress flex runs through tight chases, creating kinks that trap humidity and load up coils with debris, a pattern we also address with Euless Lennox service. Our crews have documented these conditions with before-and-after photos on hundreds of Irving jobs since 2013.

Why Trust CleanRun Air Duct Cleaning Irving for Your Lennox Air Duct Cleaning?

Tomas Reyes, who leads our operation, grew up in the Bronx and picked up his HVAC fundamentals at Bronx Community College before spending years doing hands-on duct work across the metro area. He moved the operation to DFW and has been running service calls throughout Irving, including jobs in the Las Colinas corridor, for several years running. What his regulars notice is that he pulls inspection photos before any cleaning starts and leaves a written summary of exactly what was found: settled dust, mold-like growth on duct liner, collapsed flex sections, whatever the camera shows. He also keeps a Spanish-language explanation ready for customers who’d rather hear the details in their first language.

That approach carries through to our Lennox work. We know the three product tiers because we’ve opened them up repeatedly. The Merit Series runs simpler duct configurations with single-speed blowers that don’t forgive restricted airflow. The Elite Series introduces variable-speed motors that pull more air through tighter coil fin spacing, which means dust accumulation shows up faster as uneven room temperatures. The Dave Lennox Signature Collection pairs premium efficiency with complex zoning ductwork that demands precise static pressure balancing.

Our equipment roster includes Rotobrush agitation systems, Nikro and Abatement Technologies negative-pressure extractors, and Honeywell, Aprilaire, and Guardsman filter and sealing products. These are professional-grade tools you can look up independently, and they’re what we use on your Lennox system, not consumer-grade shop vacs with brand stickers.

Every job operates under the H.A.V.E.N. Standard. Haven Standard Clause 1 requires a written price delivered before any work starts. Haven Standard Clause 3, Verified Crews, means background-checked, uniformed technicians identified by name before arrival. The 365-Day Done Right Promise backs the work in writing, not as a policy subject to manager approval.

Common Lennox Air Duct Cleaning Problems We Fix in Irving

• Mastic sealant failure at the supply plenum. On Lennox Merit and Elite systems installed during the 2005-2015 period, the mastic sealing the plenum-to-trunk takeoff dries out and cracks in Irving’s prolonged attic heat. We’ve measured static pressure losses of 0.3-0.5 inches water column on jobs where conditioned air was dumping straight into the attic through gaps you could slide a pencil through. The photo doesn’t lie - let’s look at it together before we talk about next steps. We strip the old mastic, reseal with fresh OEM-compatible product, and verify the fix with a manometer reading.
• Evaporator coil fouling in tight-fin Merit and Elite lines. Lennox coils in these series use dense fin spacing that traps dust and pollen more aggressively than looser commercial-grade designs. In Irving, where AC runs from late May through September pulling pollen-laden air continuously, we’ve pulled coils matted to the point of reducing airflow by 30% or more. The compressor works harder, energy bills climb, and the farthest rooms cool poorly. We clean the coil in place with foaming cleaner and low-pressure rinse, documenting the before and after with photos.
• Flex duct inner liner collapse near the air handler. Lennox variable-speed blowers in the Elite and Signature lines ramp up gradually, which can mask a partially collapsed flex duct run until the motor is running at full torque against a blockage. The symptom is a hot spot in the farthest room served by that trunk. We locate the collapse with a camera, then repair or replace the affected section with OEM-compatible flex duct rated for the static pressure of that Lennox model.
• Blower wheel loading on variable-speed motors. Lennox variable-speed blower motors pull high volumes of return air, and in Irving’s older homes with degraded attic insulation, that means lint and fiberglass fibers get drawn into the blower wheel cavity. The wheel becomes imbalanced, causing vibration and uneven room-by-room airflow. We remove the blower assembly, clean the wheel and housing, and document the debris volume in the photo record.
• Fiberglass duct liner degradation in Las Colinas commercial conversions. This one’s specific to Irving’s unusual building stock. The 1980s office towers along O’Connor Road and Northgate Drive that have converted to residential or mixed use retain original fiberglass-lined ductwork that sheds particulate into the air stream. When a Lennox air handler is retrofitted into these systems, the blower pulls that degraded liner material through the coil and into occupied spaces. We encounter this failure mode routinely in Irving and almost never in the residential-first call queues of Grand Prairie or Garland. The fix is liner removal or encapsulation, followed by full system cleaning.

Lennox Parts & Our Repair-vs-Replace Approach

We stock OEM-spec Lennox-compatible flex duct, mastic, and filter media on every Irving truck. For filter replacements, we use quality aftermarket products where they meet or exceed Lennox airflow specs, and we’ll show you the MERV rating and pressure-drop data before you agree to anything.

Our repair-vs-replace stance is straightforward. If a Lennox coil or blower is fouled but mechanically sound, cleaning is almost always the right call over replacement. We’ve seen competitors quote a $1,200 coil replacement for a condition that resolved with $340 of documented cleaning. The written price we deliver before work starts includes both options when there’s any ambiguity, so you decide with the evidence in front of you.

We don’t carry Lennox OEM coils or complete air handlers. For full equipment replacement, we refer to licensed HVAC contractors and provide our documented photo record to inform their scope. Call (682) 297-4068 and we’ll walk through what’s actually needed.

Our Lennox Service Process - Step by Step

1. 1
   Diagnosis with documentation. We open the Lennox air handler, insert a borescope camera into the supply and return plenums, and photograph every duct run. You see the debris, the mastic cracks, the coil condition, or the collapsed flex before we name a price. The written estimate follows Haven Standard Clause 1: one flat price per system, agreed before work starts.
2. 2
   Targeted cleaning, sealing, or repair. For evaporator coil cleaning, we apply foaming cleaner matched to the Lennox coil alloy, let it dwell, and rinse at low pressure to protect fin integrity. For duct sealing, we remove degraded mastic and apply fresh sealant, then verify with a static pressure test. For flex duct repair, we cut out the damaged section and splice in OEM-compatible replacement with proper support straps.
3. 3
   System testing and verification. We run the Lennox air handler through its full speed range, measuring static pressure at the return and supply plenums against the manufacturer’s spec for that model. Variable-speed blowers get checked at low, medium, and high stages. Room-to-room airflow is verified with a flow hood or anemometer at key registers.
4. 4
   Deliverables and warranty. You receive the documented photo record of every duct run, the written scope of work, and the 365-Day Done Right Promise in writing. If the work is not right, we make it right. That’s Haven Standard Clause 7, and it’s not subject to manager approval.

Lennox Products We Service & Install in Irving

We clean, seal, and repair ductwork connected to Lennox Merit Series, Lennox Elite Series, and Lennox Dave Lennox Signature Collection systems, including Grapevine Lennox service. This includes single-stage and variable-speed air handlers, gas furnaces with integrated blower compartments, and heat pump configurations with indoor coil cabinets. We stock filter media and sealing supplies matched to the airflow requirements of each tier.

We do not install complete Lennox HVAC equipment. Our scope is the duct system, the evaporator coil, and the air handler blower assembly - the components that move and condition air, not the refrigerant circuit or combustion components. For full system replacement, we provide our documentation and refer to qualified HVAC contractors.

We Also Service These Brands

CleanRun’s crews are multi-brand fluent. We carry Trane-compatible and Carrier-compatible flex duct, mastic, and filter media on the same trucks, and we document before-and-after photos on those systems with the same rigor. The H.A.V.E.N. Standard and the 365-Day Done Right Promise apply regardless of brand. Our independence from any single manufacturer is what lets us recommend the right fix rather than the right part number.

FAQs - Lennox Air Duct Cleaning Service in Irving

Is CleanRun Air Duct Cleaning Irving authorized by Lennox?

No. We are an independent Lennox service provider, not a Lennox dealer or authorized representative. We’re not affiliated with Lennox International, and we don’t represent their warranty program. What we offer is hands-on expertise with Lennox duct configurations, coil designs, and blower assemblies from thousands of field jobs across DFW.

Do you use genuine Lennox/OEM parts?

We use OEM-spec Lennox-compatible flex duct, mastic, and filter media. For filters, we also use quality aftermarket products that meet or exceed Lennox airflow specifications, and we show you the MERV rating and pressure-drop data before installation. We don’t use counterfeit or out-of-spec parts that could damage your system.

How long does Lennox service take?

A typical residential evaporator coil cleaning and duct inspection on a Lennox Merit or Elite system takes 2.5 to 4 hours. Full system cleaning with duct sealing on a larger Signature Collection zoned system can run 5 to 7 hours. We don’t rush the documentation phase - the photo record is included as a standard deliverable, not an afterthought. Call (682) 297-4068 for a written estimate with time expectations for your specific setup.

What Lennox models/series do you cover?

We service ductwork and air handler components for the Lennox Merit Series, Lennox Elite Series, and Lennox Dave Lennox Signature Collection. This includes single-stage, multi-stage, and variable-speed configurations. We don’t service the refrigerant circuit or combustion components - those require a licensed HVAC contractor.

Will service void my Lennox warranty?

Proper cleaning and sealing of accessible ductwork and coils won’t void your Lennox warranty. We don’t open sealed refrigerant systems or electrical enclosures beyond the access panels designed for homeowner or technician maintenance. If your system is under warranty and you’re concerned, we’ll document our scope in writing before starting so you have a record of exactly what was touched. For warranty claims on mechanical components, you’ll still need a Lennox-authorized dealer.

How much does Lennox air duct cleaning cost in Irving?

Lennox evaporator coil cleaning in Irving typically runs $280-$420 for a single residential system. Full duct cleaning with negative-pressure extraction and register-by-register agitation ranges $420-$680 for a standard single-story home. Duct sealing with fresh mastic, measured and verified, adds $180-$340 depending on plenum size and accessibility. These are whole-system prices, not per-vent teaser rates. We deliver one written price before work starts, every time, under Haven Standard Clause 1. Call (682) 297-4068 for an exact quote - estimates are free.

Does Lennox recommend a specific duct cleaning frequency for homes in Irving?

Lennox publishes general maintenance guidelines but doesn’t specify Irving’s climate conditions. Based on our field data, Lennox systems in Irving need evaporator coil inspection every 18-24 months due to the prolonged AC season and pollen load. Homes near the Elm Fork Trinity River corridor, where humidity runs higher, may need more frequent checks for mold-like growth on duct liner. We document actual conditions with photos rather than selling on a calendar.

Will cleaning the evaporator coil on my Lennox Merit system void my warranty?

No, if done properly. We clean coils through the access panel designed for maintenance, using foaming cleaner and low-pressure rinse methods that don’t bend fins or damage the coil casing. We don’t cut refrigerant lines or remove the coil from its sealed circuit. Our written scope specifies exactly what we touch, so you have documentation if any warranty question arises.

My Lennox variable-speed air handler sounds louder than usual after duct work - what’s happening?

Variable-speed blowers compensate for restricted airflow by ramping up. If a duct run was partially blocked or a return filter was upgraded to a too-dense MERV rating without checking static pressure, the motor works harder and gets louder. We measure total external static pressure against Lennox’s spec for your model - typically 0.5 inches water column for many Elite systems - and trace the restriction. Often it’s a collapsed flex section or a filter choking the return. The fix is mechanical, not a new motor.

Do Lennox Signature Collection systems need different duct sealing methods than Merit or Elite?

Signature Collection systems run at higher static pressure to achieve their efficiency ratings, which makes seal integrity more critical. The same mastic products work, but we pay closer attention to the plenum-to-trunk joints and any zoning dampers, since leaks in a high-static system waste more conditioned air. We verify with a manometer, not a hand-wave.

Can you reroute a crushed flex duct run on a Lennox system without replacing the whole branch?

Usually, yes. If the crush is localized - often where a flex run bends around a framing member or gets pinched by insulation - we cut out the damaged section and splice in a replacement length with a metal collar and proper support straps. We only replace the full branch if the original flex is degraded throughout or undersized for the Lennox air handler’s rated airflow. The camera shows which it is.
