Lennox Air Duct Cleaning in Acworth, GA | Cardinal Air Duct Marietta
Lennox air duct cleaning in Acworth typically runs $450 – $850 for a full system on a 1,500 – 2,500 square-foot home, and we complete most jobs in a single visit. We’re Cardinal Air Duct Marietta, an independent Lennox service provider serving Acworth homeowners with professional Rotobrush and Nikro equipment. The difference here comes down to what’s actually inside Acworth ductwork: decades of pine pollen, construction debris from original 1990s builds, and flex duct that’s never been replaced. Omar Haddad and our crew work on Lennox systems across Acworth every week – including Lennox sales & service calls that start with cleaning but often reveal deeper airflow issues. Call (762) 216-4075 for a written quote before any work begins.

Why Acworth Residents Choose Us for Lennox Service
We work on Lennox air handlers, furnaces, and duct systems daily across Acworth, from split systems with CBX air handlers to G61 and EL series furnaces. That daily exposure means we understand how Lennox airflow and filtration behavior impacts duct contamination in this specific climate. Omar Haddad trained in heating and ventilation systems at Los Angeles Trade-Technical College and spent years learning the difference between a duct that needs brushing and one that needs replacing – without guessing. That matters in Acworth, where original flex duct from 1980s – 2000s construction is reaching the end of its service life. We’re an independent service provider, not manufacturer-affiliated, so our recommendations are based on what your Lennox system actually needs in this climate, not a corporate script. Every job includes a written price before work starts, background-checked uniformed technicians, and the 365-Day Done Right Promise: if it’s not right within a year, we return and correct it at no charge.

Common Lennox Air Duct Cleaning Problems We Solve in Acworth
- Variable-speed ECM blowers pulling debris into returns. Lennox variable-speed blowers run longer and pull more air through the system, which means neglected filters let more pollen and dust into return ducts. In Acworth’s long pine pollen season, that debris accumulates fast in homes with original flex duct.
- Slab-coil evaporator designs trapping pollen and construction dust. Lennox slab coils sit horizontally and have large flat surfaces that catch debris. In Acworth’s humid subtropical climate, that trapped material holds moisture, reducing airflow and pushing dust through supply ducts into living spaces.
- Fine metallic dust from high-efficiency secondary heat exchangers. Lennox high-efficiency furnaces with secondary heat exchangers shed fine metallic particles over time. In 1990s – 2000s suburban homes around Acworth, that dust accumulates in ducts and requires aggressive brushing, not just vacuuming.
- Communicating systems settling fine pollen deep in duct runs. Lennox iComfort communicating systems often run long cycles at low airflow. Near Lake Acworth and Allatoona, that allows fine pine pollen to settle deep in duct runs where standard cleaning misses it.
- Collapsed flex duct from attic heat and original installation. Much of Acworth’s housing stock has flex duct in attics that was installed decades ago. Attic heat, humidity, and poor original routing cause collapses, especially where duct passes over trusses – restricting airflow and pulling debris from unconditioned spaces.
Lennox Service in Acworth: What Local Conditions Mean for Your Equipment
In Acworth, Lennox air handlers in attic-mounted systems often draw in fine pine pollen from surrounding forested lots, and many 1980s – 2000s flex duct runs contain original construction debris from slab-foundation subdivisions like Brookstone – something you won’t see in nearby Kennesaw or Woodstock to the same degree. Our tech opened the attic return in a Brookstone home off Baker Road and found the Lennox CBX air handler’s blower wheel caked with a mix of pine pollen and drywall dust that had pulled through a torn flex return. The original flex duct had collapsed where it passed over a truss, so we replaced the run, cleaned the evaporator coil and blower, and sealed the plenum with mastic – airflow jumped and the homeowner’s nighttime allergies eased. Homes near Lake Acworth and Allatoona add another layer: sand and lake humidity residue that settles into ducts and creates a gritty paste when mixed with pollen. Newer subdivisions west of I-75 tend to have dryer lint and construction dust from recent builds. Each part of Acworth has its own duct signature, and we clean for what’s actually in your system.
Lennox Models & Products We Service in Acworth
We service the full Lennox product range across Acworth: the Merit Series (ML180, ML195 gas furnaces), Elite Series (EL296V, EL280 gas furnaces and CBX air handlers), Dave Lennox Signature Series (SL280, SLP98V), and XC/XP series air conditioners and heat pumps. We use OEM Lennox filters, coils, and blower components where system integrity matters, but recommend quality aftermarket mastic, flex duct, and grilles for repair work to match Acworth’s humidity and pollen load. We repair before replacing unless the duct or component is beyond economical salvage. Our trucks carry common Lennox filter sizes and duct sealing materials, which means faster turnaround for Acworth homeowners who don’t want to wait on parts.

AfterLennox Service Pricing in Acworth
Air Duct Cleaning - Acworth typically runs $450 – $850 depending on home size, number of returns, and how long it’s been since the last cleaning. Homes with original flex duct from the 1980s – 2000s often land on the higher end because deteriorated ductwork requires more careful handling. Evaporator coil cleaning, flex duct repair, and duct sealing are quoted separately after inspection, always in writing before work starts. We don’t do per-vent pricing or teaser coupons that balloon into bigger invoices. A free estimate includes a visual inspection of accessible ducts, a written quote, and straight answers about what actually needs doing. Call (762) 216-4075 for an exact quote for your Acworth home.

FAQs – Lennox Air Duct Cleaning in Acworth
Variable-speed ECM blowers run longer and move more air, which pulls more pollen and debris into return ducts when filters aren’t changed regularly. In Acworth’s long pine pollen season, we recommend cleaning every 3 – 4 years for homes with variable-speed Lennox systems, compared to 4 – 5 for single-speed units. Call (762) 216-4075 to schedule an inspection and find out where your system stands.
Yes, and we see it regularly in 1980s – 2000s subdivisions like Brookstone and Bentwater. Drywall dust, wood scraps, and even drink cans from original construction sit in flex duct for decades because they’re too heavy for normal airflow to dislodge. We remove it with rotary brush systems and HEPA extraction – not just vacuuming what’s near the register.
Lennox slab-coil designs have large flat evaporator surfaces that catch airborne particles, and Acworth’s pine pollen load makes them dirty faster than A-coil designs. When the coil loads up, airflow drops and dust gets pushed through supply ducts. We include coil inspection with every duct cleaning and recommend cleaning coils on the same visit.
Yes, particularly in attics where humid air infiltrates leaky duct connections. Leaks pull unconditioned, pollen-heavy attic air into your system, which then distributes through your home. Sealing with mastic – not tape – keeps that humid, dirty air out and improves Lennox system efficiency. Call (762) 216-4075 for a sealing assessment.
High-efficiency Lennox furnaces with secondary heat exchangers shed fine metallic particles as part of normal operation. In Acworth homes with original ductwork, that fine dust accumulates and requires brushing plus HEPA extraction to remove. It’s a known Lennox characteristic, not a sign your furnace is failing. Call (762) 216-4075 to have it cleaned properly.
