Lennox Air Duct Cleaning in Sylmar, CA
We clean, seal, and repair the ductwork connected to Lennox furnaces and air handlers all across Sylmar. We’re an independent company, not a Lennox dealer, and not authorized by them. What makes our work here different is simple: we know that Sylmar Lennox systems load up with fine mountain grit and ash from the Newhall Pass wind funnel, so we always start at the return grilles rather than the supply runs. Call (888) 494-4745 for a free estimate.
Why Sylmar Residents Choose Us for Lennox Service
Most companies treat duct cleaning as a side job. We don’t. Stan Maddox started this company in 2017 after spending well over a decade inspecting, cleaning, and repairing duct systems across the San Fernando Valley, and he built the whole operation around one discipline: what moves through your ventilation. That narrow focus matters when you own a Lennox system in Sylmar, because the failure modes here are specific. We’ve opened enough Lennox air handlers in 1960s and 1970s Sylmar tract homes to know exactly where grit collects, which boots leak, and what a dirty blower wheel does to airflow. We run Rotobrush and Nikro systems, the same equipment remediation pros rely on, not a shop vac bolted to a truck. If I can’t tell you exactly what we’re doing to your ducts and why, I shouldn’t be in your house.
We service all of Sylmar and the surrounding north Valley. Scheduling is straightforward, and the estimate is free. We answer 24/7. Fast dispatch from 7am to 7pm, Sunday through Friday.

Common Lennox Air Duct Cleaning Problems We Solve in Sylmar
- Return-side grit loading after Santa Ana winds. Lennox air handlers in Sylmar pull from garage-adjacent returns, and within days of a wind event, the filter and blower wheel pick up a visible layer of fine tan dust and ash. We clean the full return path, not just the grille face.
- Blower wheel imbalance and rattle on older Lennox furnaces. When dry-season grit builds unevenly on the squirrel-cage blower, the wheel vibrates. Homeowners hear a rumble or rattle at startup. We remove the blower assembly, clean each fin, and check the hub before reinstalling.
- Dirty evaporator coils on Lennox cased coils. Smoke and ash residue from brushfires near the mountains combines with summer condensate on the coil. It forms a sticky mat that chokes cooling capacity and raises runtime. Coil cleaning is a standard part of our Sylmar calls.
- Leaking flex and galvanized trunk transitions on 1970s installs. Aging flex duct and taped joints at the plenum drop static pressure and pull attic grit into the supply side. We find these leaks, reseal with mastic and quality tape, and replace failed flex where needed.
- Grit concentrated in south-facing and garage-adjacent rooms. Sylmar’s position at the mouth of the San Gabriel Mountains means wind-driven particles enter the return side unevenly. Rooms nearest the garage collect dust while the rest of the house looks clean. The return grilles tell the story.
Lennox Service in Sylmar: What Local Conditions Mean for Your Equipment
Sylmar gets the worst of the Newhall Pass wind funnel plus periodic canyon-fire ash, a combination no sheltered Valley floor neighborhood deals with. The returns nearest the garage and south-facing rooms load up first. In a 1968 single-story stucco tract home off Foothill near the foothills, a customer with a Lennox G60 furnace called because every room felt dusty days after a Santa Ana blow. We pulled the garage-adjacent return grille and found a visible layer of fine tan grit and ash, then found the same residue coating the blower wheel and the cased evaporator coil. We cleaned the return and supply runs, washed the coil, cleaned the blower, and sealed the leaking flex boots at the plenum. The homeowner said the house finally stopped tasting like the hills. That’s not a one-off pattern. It repeats on nearly every Lennox system we open in Sylmar after a wind event.
Lennox Models & Products We Service in Sylmar
We’ve worked on Lennox systems across the north Valley for years, from older G60 and G61 series gas furnaces common in 1990s and 2000s Sylmar retrofits, to Merit Series air handlers, to variable-speed CBX and CBXH-style air handlers paired with newer XC and SL condensers from the Elite and Signature Collection lines. Our job is the duct side: return runs, supply trunks, boots, plenums, coils, and blower assemblies. We use genuine Lennox OEM filters, gaskets, and coil or vestibule components where fit matters, and quality aftermarket flex, mastic, and tape for duct repairs. We’re an independent shop, not manufacturer-affiliated, so our credibility comes from the systems we actually open, clean, and reseal. If a Lennox furnace or coil is near end of life, we’ll say so honestly rather than keep cleaning a leaking system. Most Sylmar calls are recoverable with cleaning, sealing, and a filter strategy.

AfterLennox Service Pricing in Sylmar
Every job is priced per system by a written estimate. The size of the home, the number of returns, the condition of the flex and boots, and whether the evaporator coil needs washing all affect the final number. A single-story 1970s Sylmar tract home with one return and a standard supply layout will land on the lower end. A larger two-story with multiple returns, a dirty cased coil, and leaking boots will run higher. The estimate is free, and the written number is the number. No per-vent pricing, no bait-and-switch after the van arrives. We clean the whole system for one flat price, agreed before work starts. Call (888) 494-4745 for an exact quote.

FAQs – Lennox Air Duct Cleaning in Sylmar
Because Sylmar sits at the mouth of the Newhall Pass wind funnel and the San Gabriel Mountains. Santa Ana winds push fine tan dust and ash down through Placerita Canyon and across residential streets, and your Lennox air handler pulls that air right into the return grilles. The returns nearest the garage and south-facing rooms load first. Call (888) 494-4745 if you’re seeing grit within days of a wind event. A thorough return-side cleaning plus a better filter strategy usually settles it.
Yes. Sylmar summers regularly top 100°F, and when smoke or ash residue from canyon fires mixes with coil condensate, it bakes into a sticky mat on the Lennox cased coil. That layer insulates the coil and chokes heat transfer, which means longer runtimes and weaker cooling. We wash the coil as part of our duct cleaning, and it’s one of the most direct improvements we make on Sylmar systems. Call (888) 494-4745 for an estimate.
Dry-season grit and ash build unevenly on the squirrel-cage blower wheel, throwing it out of balance. The vibration shows up as a rumble or rattle at startup, and it gets louder as the debris accumulates. We pull the blower assembly, clean every fin, and check the hub and motor mounts before reinstalling. It’s a known Lennox failure mode in wind-exposed areas like Sylmar.
Where fit matters, yes. We use genuine Lennox OEM filters, gaskets, and coil or vestibule components, and quality aftermarket flex, mastic, and tape for duct repairs. We’re an independent shop, not a Lennox dealer, so we choose what actually fits and holds up. Clean ducts are the start. Sealed, repaired ducts are the finish.
Yes, especially if the ducts have never been opened. Original galvanized trunk lines in 1970s Sylmar homes often have decades of accumulated grit, and the flex transitions at the boots are usually leaking by now. Cleaning the runs and sealing the leaks drops static pressure and stops attic grit from entering the supply side. The difference is immediate in rooms that always felt dusty. Call (888) 494-4745 and we’ll walk through what we’d do.
