Lennox Air Duct Cleaning in Floris, MD | Apex Air Duct Cleaning Maryland
We provide independent Lennox air duct cleaning service throughout Floris and the 20171 ZIP, specializing in the aging flex-duct systems found in nearly every home here. What sets our work apart is simple: we’ve cleaned more Lennox G50, G51MP, and G16 furnace-connected ductwork in western Fairfax County than most competitors have touched in their entire operation, and Robert Garcia personally leads every job with Rotobrush and Nikro extraction systems. If your Lennox system is pushing 20-35 years old — standard for Floris’s 1988-2005 construction wave — we can tell you exactly what’s happening inside those attic runs before we start. Call (855) (301) 301-6549 for a free estimate.
Why Floris Residents Choose Us for Lennox Service
Robert Garcia grew up in Silver Spring, spending weekends near Sligo Creek Park before enrolling in the HVAC and Sheet Metal Technology program at Montgomery College in Rockville. He picked up air duct cleaning straight out of that program and has spent 14 years doing it hands-on across Maryland. That background matters when he’s crawling through a Floris attic, reading the sag patterns in a 30-year-old Lennox flex-duct run like someone else might read a map.
We’re not a general HVAC contractor grabbing duct jobs between installs. We’re indoor air quality specialists with 254 reviews averaging 4.7 stars, and Robert handles every Lennox job personally. Our Abatement Technologies containment gear prevents cross-contamination during cleaning — a real concern when you’re dealing with decades of construction dust and possible microbial growth. We stock OEM Lennox filters and compatible sealants for fast turnaround, and we know the airflow requirements for every model family we touch. No dispatching day-labor crews. No shop-vac shortcuts. Just focused work on the equipment that heats and cools your home.
Common Lennox Air Duct Cleaning Problems We Solve in Floris
- Fiberglass duct liner shedding from original Lennox plenums. The 1988-2005 homes dominating Floris have flex-duct liner now 25-40 years old. That liner degrades into airborne particles. Our Rotobrush systems use gentle rotary action — aggressive enough to extract shed fiberglass, controlled enough to avoid tearing what’s left.
- Flex-duct sagging and crimping at attic takeoffs. Multi-zone Lennox systems with long attic runs develop low spots that trap debris and moisture. Rooms at the far end of the system get weak airflow. We run video inspection first, locate every crimp, then clean and repair.
- Mold colonization in unconditioned attic returns. Northern Virginia summers push dew points into the low-to-mid 70s°F, and the wooded Difficult Run corridor traps humidity. Condensation forms on poorly insulated flex ducts. We remove debris, then apply antimicrobial fogging — Guardsman-rated treatments, not generic sprays.
- Particle loading from Route 28 corridor construction. The commercial and data-center boom off Centreville Road and Fox Mill Road generates fine dust that infiltrates Lennox return-air intakes. We consistently find gray particulate loads far heavier than in quieter Fairfax County suburbs. Every Floris cleaning includes evaporator coil inspection — that dust fouls coils fast.
- Static pressure imbalance from degraded ductwork. As flex ducts age, they lose their original diameter and smooth interior surface. Your Lennox furnace works harder, burns more gas, delivers less comfort. We measure static pressure before and after. Numbers don’t lie.
Lennox Service in Floris: What Local Conditions Mean for Your Equipment
Floris’s master-planned communities were built almost exclusively between 1988 and 2005, meaning every original flex-duct system in the 20171 ZIP is now 20-35 years old — well past its 15-25 year service life. This isn’t a theoretical concern. Drive through Franklin Glen, McNair Farms, or any subdivision off Centreville Road, and you’re looking at neighborhoods where the ductwork is failing in predictable, visible ways: sagging between joists, insulation crumbling at contact points, takeoff collars separating from trunk lines. For Lennox owners specifically, this matters because the G50 and G51MP furnace series installed in many of these homes were designed for specific static pressure ranges. When the ductwork degrades, the furnace operates outside spec — cycling more, heating less evenly, shortening its own lifespan. We’ve developed a systematic approach for Floris: video-guided cleaning to assess what’s salvageable, targeted duct repair for sections that can be restored, and honest replacement recommendations only where flex duct has collapsed or torn beyond repair. Clean ducts aren’t a luxury — they’re just what the system was supposed to have all along.
Lennox Models & Products We Service in Floris
We work on the full range of Lennox residential equipment found in Floris homes, from legacy systems still running to newer installations. Our 14 years of focused duct cleaning means we understand the airflow characteristics and duct sizing requirements for each family:
- Lennox G50/G51MP furnace series (1980s-1990s): Common in early Floris builds, these units connect to flex-duct systems now at end-of-life. We stock OEM-compatible filters and mastic sealants sized for their plenum connections.
- Lennox G16 gas furnace (1970s-1980s): Fewer remain, but we encounter them in occasional renovation holdouts. Their larger duct collars require specific adapter fittings — we carry them.
- Lennox Merit Series air handlers (2000s-present): Found in newer Floris construction and retrofits. These systems are more sensitive to coil fouling; our cleaning includes full evaporator access.
- Lennox SLP98V variable-speed gas furnace: Premium installations where duct condition directly affects the variable-speed motor’s efficiency. Static pressure testing is critical here — we perform it.
We source OEM Lennox filters and sealants when available, and select aftermarket components that meet or exceed OEM specifications for cost-sensitive repairs. Nothing goes on your system that Robert wouldn’t put on his own.
Lennox Service Pricing in Floris
Most complete Lennox air duct cleaning jobs in Floris fall between $380 and $620 for a typical two-story colonial with 12-18 vents. Several factors move that needle: the number of zones, accessibility of attic runs, whether we find mold requiring antimicrobial treatment, and if flex-duct repair or partial replacement is needed. Video inspection runs $89 separately, but we waive it when you proceed with full service. Dryer vent cleaning bundled with duct service starts at $149 — worth considering given the fire risk in lint-heavy systems.
Every estimate is free, in-home, and specific to your Lennox setup. We’ll show you what we find before quoting. Call (855) 301-6549 to schedule — we can usually get to Floris properties within 24-48 hours.

FAQs — Lennox Air Duct Cleaning in Floris
Duct cleaning almost always helps, and in Floris it’s usually the primary cause. The Route 28 construction dust and degraded flex-duct liner in 20-35 year old systems loads filters prematurely. We’ve cleaned ducts in Floris homes where filter life doubled afterward. The furnace may also be aging, but start with the ductwork — it’s the cheaper fix and often the right one. Call (855) 301-6549 and we’ll assess both.
Yes — that gray dust is construction particulate entering your Lennox return intakes, and it’s one of the heaviest loading patterns we see in Floris. Our Nikro extraction system removes deposited dust from duct interiors, and we seal accessible leaks to reduce future infiltration. The dust on your furniture is a symptom; the ducts are the pathway. Call (855) 301-6549 for an estimate — we know this specific Franklin Glen problem well.
Sometimes yes, often no — it depends on what video inspection reveals. Sagging ducts with intact liners usually clean up and repair well. Crushed, torn, or heavily mold-compromised sections need replacement. We give you the camera view and our honest recommendation; we’ve saved Floris homeowners thousands by repairing sections that competitors wanted to fully replace. Call (855) 301-6549 and we’ll show you exactly what you’re dealing with.
Three things: proper attic insulation on duct exteriors to prevent condensation, adequate return airflow to reduce humidity stagnation, and antimicrobial treatment after any cleaning that reveals microbial growth. We use Honeywell and Aprilaire-compatible treatments applied with controlled fogging equipment — not the spray-and-pray approach some competitors bring. The Difficult Run corridor humidity is real; we design our Floris protocols around it.
No — we’re independent specialists, not manufacturer-authorized, and that distinction works in your favor. Our duct cleaning and repair services don’t void any remaining Lennox equipment warranty because we don’t alter factory electrical or gas components. We document our work with before/after photos and static pressure readings. If your furnace or air handler still has warranty coverage, our cleaning preserves it; we don’t touch covered components. For ductwork itself — which carries no manufacturer warranty at this age — we offer our own workmanship guarantee on repairs.

Book Your Lennox Service in Floris Today
At a colonial home on Fox Mill Road in the Franklin Glen neighborhood, our crew found a Lennox G51MP furnace with severe flex-duct sagging in the attic return — the 25-year-old duct had a low spot filled with compacted gray construction dust from nearby build sites, restricting airflow to the second floor. We vacuumed 14 pounds of debris, repaired the sag with new suspenders and mastic-sealed joints, and performed a post-cleaning static pressure test that dropped from 0.78″ to 0.52″ w.c., restoring balanced airflow.
