We’re Morton’s Air Duct Cleaning, an independent Lennox service provider. Not manufacturer-affiliated, not authorized, not a dealership. We’re duct and dryer vent specialists who work on Lennox equipment daily across Arlington’s 1960s-1980s housing stock, and we know exactly how those systems fail in North Texas attics.

Why Arlington Residents Choose Us for Lennox Service

Paul Adeyemi, who leads our team, learned ventilation mechanics at Los Angeles Trade-Technical College and has spent nearly two decades working inside the walls of homes across the Los Angeles basin. When he says “Before we start, let me show you exactly what we found and exactly what it will cost to fix it,” that’s how every Arlington job begins. You see the video footage. You get the written price. Then we work.

Our techs understand Lennox air distribution systems the way a mechanic understands a specific engine. We know the Merit Series flex-duct failure points, the Elite Series coil fouling patterns, and the legacy CompleteHeat quirks still present in some older Arlington homes. We bring Rotobrush and Nikro equipment, lay down shoe covers and drop cloths before anything enters your home, and send you a photo of the clean-up before we leave. The 365-Day Done Right Promise backs every job, stamped on the work order, not mentioned after the fact.

We’re part of the Cedarwell family of independently owned companies, which means every Arlington visit follows the Cedarwell Care Promise. Now Lennox sales & service pages elsewhere might talk about generic cleanings. We talk about your attic, your slab, your duct runs.

Common Lennox Air Duct Cleaning Problems We Solve in Arlington

• Brittle flex duct from attic heat cycling. Lennox systems installed in Arlington attics during the 1970s and 1980s have endured decades of 140-150°F summer attic temperatures. Flex duct insulation cracks, the inner liner compresses at bends, and airflow drops. We often find original fiberglass flex that sheds particles into the supply stream every time the blower kicks on.
• Mastic seal failure at the plenum. Arlington’s sustained 100°F+ summers cause mastic seals at the Lennox air handler plenum to dry, crack, and separate repeatedly. Each failure pulls attic air, fiberglass particles, and North Texas dust directly into your living spaces. This is chronic in slab-foundation ranch homes east of Collins Street.
• Fouled evaporator coils during pollen season. Arlington’s cedar and Bermuda-grass pollen seasons are severe, and older Lennox air handler coils foul fast. A fouled coil means the blower runs longer, pulling more contaminated air through already dirty ducts. Cleaning the ducts without addressing the coil leaves the job half done.
• Disconnected metal duct trunks in 1970s split-levels. Original or first-replacement Lennox metal trunks often have disconnected joints or collapsed takeoffs hidden above attic insulation. Our video inspection finds these routinely in Arlington homes where owners assumed the system was fine.
• Airflow loss from compressed flex at sharp bends. Installers in the 1980s often ran flex duct tight through attic corners. Decades of heat make those bends permanent kinks. Rooms at the end of those runs get almost no conditioned air, and the blower works harder than it should.

Lennox Service in Arlington: What Local Conditions Mean for Your Equipment

Arlington’s building boom between the 1960s and 1980s, when the city grew from roughly 7,000 to over 260,000 residents, left a dense inventory of tract homes now 40 to 60 years old. Almost all sit on concrete slab foundations, which in Texas meant ductwork went into the attic, not a basement. Attic temperatures here routinely exceed 140°F in summer, and that heat cycling degrades duct insulation and joint seals faster than nearly anywhere in the country. Mansfield and Southlake have newer builds. Arlington has the old stock, and old stock means Lennox systems that are quietly losing conditioned air into the attic.

Here’s what we know from working these homes. Clay soil under the slab shifts over decades, and that movement shifts the air handler platform. In older neighborhoods around Pantego, we frequently find Lennox flex duct partially collapsed or detached at the plenum because the platform has moved. Newer west-side subdivisions near Viridian, with post-tension slabs and newer duct systems, don’t see this at the same scale. If you own a 1970s or 1980s Arlington ranch home with a Lennox system, your ducts have likely been fighting the soil for years.

Lennox Models & Products We Service in Arlington

We clean and repair the air distribution side of every Lennox line you’ll find in Arlington: Merit Series, Elite Series, and Dave Lennox Signature Collection systems, plus legacy CompleteHeat units still running in some older homes. For parts, we use OEM-equivalent Lennox-compatible flex duct, mastic, and plenum connectors from trusted suppliers. Our default is repair rather than replace. If a Lennox duct component can be properly sealed and insulated, we fix it. When Arlington attic heat has destroyed flex duct beyond safe repair, we recommend replacement with high-temperature-rated duct and a mastic-sealed plenum to stop the failure cycle. Most common parts are stocked in our local inventory, so Arlington turnaround is fast.

We recently worked a 1978 split-level near Pantego where the homeowner’s Lennox system had been running with almost no airflow to the back bedrooms. Our video inspection showed original flex duct collapsed at a sharp bend and detached at the plenum because the air handler platform had shifted on the clay soil. We re-secured the plenum, replaced the crushed flex run with high-temp duct, and mastic-sealed every joint. Static pressure dropped and the back rooms finally cooled. The homeowner told us the difference was noticeable the same afternoon.

FAQs - Lennox Air Duct Cleaning in Arlington

My Arlington home has a 1990s Lennox system with attic flex duct - is cleaning even worth it if the duct is old? Yes, if the duct is intact. We’ll show you the video before cleaning. If the flex is compressed, split, or full of pinholes, cleaning alone won’t restore airflow, and we’ll tell you that plainly before quoting any work. Brushing a failed duct just pushes particles around. Call (323) 918-4345 and we’ll inspect first.

Why does my Lennox system pull in so much attic dust even after duct cleaning? Usually because the mastic seals at the plenum have failed. Once those seals crack, the blower’s negative pressure pulls attic air, fiberglass, and dust into the supply stream regardless of how clean the ducts are. We re-seal the plenum as part of our duct sealing service.

Does the clay soil in Arlington affect Lennox ductwork more than in other cities? It does. Arlington’s clay soil expands and contracts with moisture, shifting slab foundations and the air handler platforms bolted to them. That movement disconnects flex duct at the plenum and collapses runs at bends. It’s a failure pattern we see regularly in Pantego and other older Arlington neighborhoods, and far less in cities with newer housing stock. Our video inspection identifies it before cleaning starts.

How often should a Lennox system in an Arlington ranch home be duct cleaned? Every 4 to 6 years for most Arlington homes, and every 3 to 5 years if you have pets, kids with allergies, or a pollen-heavy yard. Arlington’s cedar and Bermuda-grass seasons load systems with particulate fast. If your Lennox coil is fouling annually, that’s a sign your ducts are overdue.

Can you clean the Lennox evaporator coil and blower at the same time as duct cleaning? Yes, and in Arlington we recommend doing both together. A clean duct system feeding a fouled coil just re-contaminates the air. We’ll clean the coil and blower wheel during the same visit, and you’ll see before-and-after photos of both. Call (323) 918-4345 for a combined quote.
