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.

AfterLennox Air Duct Cleaning in Houston, NY | CleanRun Air Duct Cleaning
CleanRun Air Duct Cleaning provides independent Air Duct Cleaning - Houston for Lennox systems, and the work here differs from any other market we serve. Houston’s slab-foundation homes push nearly every foot of Lennox ductwork through unconditioned attics that bake at 140 to 160 degrees all summer, which changes how fast flex duct degrades and how aggressively mold takes hold. We’re not a Lennox dealer or authorized affiliate. We’re independent specialists who know exactly how Lennox equipment behaves in this specific climate. Call (806) 606-6902 for a written price before any work starts.
Why Houston Residents Choose Us for Lennox Service
We’ve been inside enough Houston attics to know what Lennox systems do here that they don’t do in drier cities. The higher static pressure Lennox units run means airflow hits every kink, sag, and undersized run harder. In a Houston attic, that translates to condensation at joints, mold inside supply runs, and flex duct collapsing faster than it would in a basement state. Tomas Reyes, our owner and lead technician, grew up in Woodside, Queens and completed his HVAC coursework at Queensborough Community College before spending years working residential duct systems across all five boroughs. He started CleanRun with one rule for our HVAC Cleaning in Houston: the camera goes in before the sales pitch comes out.
We photograph every duct run before and after. We name the price in writing before a single panel comes off. That’s the way we’ve worked since 2013, and it’s why Houston homeowners who own Lennox equipment keep our number.
Common Lennox Air Duct Cleaning Problems We Solve in Houston
- Flex duct kinking and collapsing in unconditioned attics. Lennox’s higher static pressure combined with 150-degree attic heat softens flex duct over time. We find kinked, sagging, and collapsed runs regularly in Houston homes built between the 1960s and 1990s. The fix is often replacement with properly supported R-8 duct, not just cleaning.
- Condensation and mold at poorly sealed Lennox duct joints. Gulf Coast humidity means any air leak at a joint becomes a condensation point within months. The camera shows mold staining inside supply runs long before homeowners smell it. We clean the system and seal joints with mastic and aluminum tape that meets SMACNA standards.
- Oversized Lennox AC units on original undersized ductwork. Houston tract homes often had small duct runs installed decades ago, then got larger Lennox condensers during a replacement. The mismatch causes excessive leakage, dust infiltration, and weak dehumidification. Cleaning helps, but we’ll tell you honestly when the ductwork itself is the problem.
- Floodwater intrusion after Houston flood events. In Meyerland, Friendswood, and parts of Kingwood, water that reached air handlers during Harvey and earlier storms pushed mold spores directly into Lennox duct systems. This creates a post-flood cleaning and testing demand that most other metro areas never see.
- Decades of Gulf Coast particulate buildup. Houston AC systems run nine or more months per year. Original 1970s through 1990s flex duct in homes from Spring Branch to Clear Lake is often coated with years of dust, pet dander, and biological growth that no filter ever caught.
BeforeAfterLennox Service in Houston: What Local Conditions Mean for Your Equipment
Here’s the thing that makes Lennox duct work different in Houston than in Dallas, Phoenix, or any basement city: slab-on-grade construction means there is nowhere to put ductwork except the attic. A Lennox system moving air through a 150-degree attic in August is doing something no manufacturer’s test lab fully replicates. The flex duct expands and softens. The joints pull apart. The cooled air inside the duct hits the hot, humid attic air at every small gap, and condensation forms inside the run, not just outside. We’ve cut open original flex duct in Sharpstown homes and watched water drip out of a supply run on a 95-degree day. That’s a Houston problem. And it’s why we inspect every run with a camera before recommending anything. The photo tells you what’s in there. Everything else is just paperwork.
Lennox Models & Products We Service in Houston
We service the full Lennox residential lineup: the Merit Series, Elite Series, Signature Collection, and Dave Lennox Signature Collection. Our crews work on heat pumps, air handlers, condensers, and the duct systems connected to them. When cleaning reveals damaged components that need repair, we use genuine Lennox replacement parts. For duct sealing, we use high-quality mastic and aluminum tape that meets SMACNA standards, regardless of brand. We keep common Lennox-compatible fittings and R-8 flex duct on our trucks so most repairs in Houston don’t wait on a parts order. If your Lennox flex duct is degraded, kinked, or undersized for the unit’s airflow, we’ll recommend repair or replacement rather than selling a cleaning that won’t solve the problem. That’s the only honest call to make, and we make it every time. For a broader look at the equipment we handle, see our Lennox sales & service page.
Lennox Service Pricing in Houston
Air duct cleaning for a typical Houston slab home with a single Lennox system runs between $450 and $900. Larger two-story homes or properties with multiple systems run $800 to $1,500. Several factors move the number: the number of supply and return runs, how much debris the camera shows, whether mold remediation or sanitizing is needed, and whether we find collapsed flex duct that requires replacement. Every job gets a written price before any work starts. That’s Haven Standard Clause 1. No exceptions. If you have a competitor’s written estimate, bring it. We’ll put our number next to it in writing, free. Call (806) 606-6902 for an exact quote on your Lennox system.

FAQs - Lennox Air Duct Cleaning in Houston
Houston’s combination of nine-plus months of AC runtime, Gulf Coast humidity, and attic-installed ductwork means your Lennox system cycles air through ducts almost continuously in conditions that promote mold, dust mite, and allergen accumulation. The condensation risk at duct joints is near year-round here, so biological growth inside ductwork becomes a structural issue faster than in drier metros. Most Houston Lennox systems benefit from inspection every two to three years. Call (806) 606-6902 and we’ll put a camera in your ducts for an honest look.
Yes, in most cases it eliminates the odor, but only if the cleaning includes the air handler and all supply and return runs. Floodwater that reached mechanical rooms pushed mold spores throughout the duct system. We clean the full system, sanitize where needed, and photograph the interior before and after. If mold has penetrated the flex duct lining itself, we’ll recommend replacement of those sections rather than a cleaning that won’t hold. Call (806) 606-6902 for a written assessment.
Expect significant accumulation. In Houston homes from that era, original flex duct often shows a lining of dust, pet dander, construction debris, and biological film. The camera typically reveals a quarter-inch to half-inch of particulate coating at the first elbow and heavier deposits near the plenum. We’ll show you the before photos and then the after photos as part of our standard documented record. Call (806) 606-6902 to schedule an inspection.
Yes. Lennox equipment is engineered to move air efficiently, but that same pressure pushes harder against any weak point in your duct system. In a Houston attic where flex duct is already softened by heat, the result is more leakage at joints and seams than you’d see with a lower-static system in a cooler climate. Sealing those joints with mastic after cleaning is the single best thing you can do for your Lennox system’s efficiency in Houston.
Yes. We service Lennox air handlers in garages, attics, and utility closets throughout Houston, including Meyerland. If floodwater reached the unit, we inspect the air handler interior, clean the blower and coil, sanitize the cabinet, and work through every duct run connected to it. Call (806) 606-6902 and we’ll schedule a camera inspection first, then give you a written price for whatever the system actually needs.
