Lennox Air Duct Cleaning in Spring, TX | Hollis Air Duct Houston
We provide independent Lennox air duct cleaning and repair across Spring, TX. What makes our Lennox work different here is simple: we know how Spring’s oak pollen, attic humidity, and shifting clay soil combine to clog and crack Lennox duct systems in ways a generic duct cleaner won’t catch. If you own a Lennox system in Spring, call us at (713) 936-5800 for a written estimate before any work starts.
We’re not a manufacturer affiliate or an authorized Lennox dealer. We’re an independent service provider that works on Lennox equipment every week, from 1990s builder-grade units in older Spring subdivisions to new high-efficiency models in Gleannloch Farms. That independence means we answer to you, not to a corporate warranty flowchart. Hollis Air Duct Houston is part of the Garrison Partners family, and every job runs on The Garrison Standard: written prices, written guarantees, and a 365-Day Done Right Promise. We also handle Lennox sales & service across the broader Houston metro.
Why Spring Residents Choose Us for Lennox Service
Roy Castellanos, our owner, grew up in Los Angeles and learned his trade fundamentals at Los Angeles Trade-Technical College before spending well over a decade servicing Houston homes. He’s run jobs out in the Energy Corridor where ductwork hadn’t seen a brush since the Clinton administration. That experience matters because Lennox systems in Spring carry a specific set of problems, and Roy trains our techs to spot them before they become expensive failures.
We work on Lennox equipment daily across our Spring service area, so we know exactly where dust, pollen, and mold accumulate in the ductwork and air handlers. Background-checked, uniformed technicians arrive inside the quoted window. The price is written down before we touch anything. And if the work fails within a year, we come back and make it right at no charge. That’s the 365-Day Done Right Promise, and it’s in writing on every job.

Common Lennox Air Duct Cleaning Problems We Solve in Spring
- Flex ducts pulling loose at the boot in attic installations. Spring’s hot attics bake flex duct until the plastic collar loosens. When a duct separates, your Lennox system pulls in 140-degree attic air and blown insulation. We reconnect the duct, seal the joint with mastic, and clean the affected supply runs.
- Return ducts clogged with construction dust and pet hair. Many Spring homes built since the 1990s have central hallway returns that collect everything tracked through the front door. A clogged return starves the blower on Lennox Elite and Merit series furnaces, reducing airflow and driving up runtime. We clean the return plenum and replace the filter with an OEM Lennox filter when possible.
- Evaporator coils on older Lennox R-22 units growing mold. Spring’s humidity averages over 70% for much of the year. On older Lennox air conditioners still running R-22 refrigerant, the evaporator coil sits wet for months, and mold takes hold. We clean the coil and the supply ducts downstream, because once spores are in the ductwork, coil cleaning alone won’t stop them from recirculating.
- Clogged secondary heat exchangers in high-efficiency Lennox furnaces. Years of unfiltered return air cakes fine dust into the secondary heat exchanger on models like the EL296V. This restricts airflow, raises flue temperatures, and shortens the furnace’s life. A full system cleaning pulls that debris out before it becomes a cracked heat exchanger.
- Duct joints separating under slab movement east of I-45. In neighborhoods like Cypresswood, Spring’s clay soil expands and contracts with rain and drought. The slab shifts enough to separate Lennox duct joints under the home, creating hidden leaks that pull in insulation and humidity. We locate those leaks with video inspection and reseal them from the inside.
Lennox Service in Spring: What Local Conditions Mean for Your Equipment
Here’s something specific to Spring that doesn’t apply equally in Humble or The Woodlands. East of I-45, the clay soil under neighborhoods like Cypresswood does something that directly attacks Lennox ductwork. Clay swells when it rains and shrinks when it’s dry. Over a decade of wet springs and dry Augusts, that movement shifts the concrete slab enough to separate duct joints under the house. The result is a Lennox system that runs constantly but never seems to cool the upstairs, because a third of the conditioned air is leaking into the crawl space or pulling insulation and humid attic air back into the return. Standard duct cleaning won’t fix that. Our video inspection finds the separated joints, and we reseal them with mastic before cleaning the affected runs. If you live east of I-45 and your Lennox system has gotten louder or weaker over the years, that slab movement is the first thing we check.
Lennox Models & Products We Service in Spring
Our techs work on the full Lennox residential lineup that shows up in Spring homes. That includes Elite Series gas furnaces like the EL296V and EL195E, Signature Series air conditioners like the XC21 and XC25, Merit Series heat pumps like the ML14XP1, and the Dave Lennox Signature Collection air handlers in the CBA series. We prefer OEM Lennox filters and access panels when replacement is needed, but for long flex duct runs in Spring attic heat, we use high-quality aftermarket flex duct and mastic that meets or exceeds factory specs. We’ll repair a duct section rather than replace it unless it’s torn or collapsed. Air duct cleaning, dryer vent cleaning, and duct sealing are our core services, and we stock common Lennox-compatible parts locally so Spring jobs don’t wait on a warehouse in another state.

AfterLennox Service Pricing in Spring
A full Lennox air duct cleaning on a typical Spring two-story home runs between $450 and $750, depending on the number of supply and return runs, accessibility of the attic, and whether coil cleaning or video inspection is included. Flex duct repair adds $150 to $400 per affected run, and duct sealing with mastic runs $40 to $80 per joint. What drives cost in Spring specifically is attic accessibility and the age of the ductwork. Homes built in the 1980s and 1990s often have tighter attic clearances and more brittle flex duct that needs replacement rather than reconnection. A written estimate is free, and the price does not move once we’ve inspected the system. Call (713) 936-5800 for an exact quote on your Lennox system.

FAQs – Lennox Air Duct Cleaning in Spring
Every 3 to 5 years is the right range for most Spring homes, but if you have live oaks or pines on your lot or you’re in a master-planned neighborhood with heavy landscaping, every 2 to 3 years makes more sense. Oak pollen season in Spring peaks in March and April, and that pollen settles into return ducts and collects on the blower wheel. Homes near Augusta Pines or Gleannloch Farms with mature tree coverage tend to need more frequent cleaning than homes on open lots. Call (713) 936-5800 and we’ll inspect your ducts and give you a straight answer on timing.
Yes. Variable-speed blowers like those in the EL296V and XC25 series need negative-pressure cleaning, not aggressive brushing through the blower housing. We use Rotobrush rotary brush systems and Nikro negative-air machines to pull debris out of the ducts without forcing it through the blower wheel. The blower is isolated during cleaning, and we inspect it before and after. This is one reason we don’t use the lowest-bid cleaning method; a careless crew can damage a variable-speed motor that costs over $1,000 to replace.
The mold is most likely on the evaporator coil inside the air handler, not in the ducts themselves. In Spring’s humid climate, the coil stays wet for months, and organic dust that passes through the return duct feeds mold growth on the coil’s surface. From there, spores travel through the supply ducts and into your living space. Cleaning the ducts alone won’t stop it. The coil has to be cleaned, the supply runs sanitized, and the drain pan checked for proper slope. We do all three on a full system cleaning.
No. The evaporator coil sits inside the air handler, and the supply ducts run downstream from it. Cleaning the coil removes mold and debris at that point in the system, but anything already lodged deeper in the supply runs stays there until those ducts are cleaned separately. We recommend doing both at the same time, because once the coil is clean, air moves faster through the system and can dislodge loose debris into the ducts, recirculating it through the home. The combined service is more efficient than doing them months apart. Call (713) 936-5800 for a combined quote.
Yes, and this is a common job in Cypresswood specifically. The clay soil east of I-45 expands and contracts enough to shift the slab, and that movement separates duct boots from the duct runs under the floor. We access the boot, reconnect the duct with mastic and mechanical fasteners, and video-inspect the run to confirm there are no other separations further down the line. If the duct is collapsed from years of movement, we’ll replace that section rather than patch it. Call (713) 936-5800 and we’ll schedule a video inspection to find every separated joint, not just the one you can see.
