Lennox Air Duct Cleaning in Citrus, CA | Elite Air Duct Cleaning Service Los Angeles
We provide independent Lennox air duct cleaning and system service across Citrus, CA — not as an authorized dealer, but as a foothill-specialist crew that’s learned how Lennox equipment behaves when attic temperatures crack 150°F and wildfire ash from the Angeles National Forest settles deep in supply trunks. If your Lennox system is pushing dust, carrying smoke odor, or struggling to keep up after a fire season, we’ll inspect it with a video scope, clean what can be saved, and tell you straight when the ductwork itself needs replacement. Call (866) 359-7544 for a free estimate — Matthew Gonzalez is on the job.
Why Citrus Residents Choose Us for Lennox Service
Matthew Gonzalez grew up in Boyle Heights and has spent 11 years crawling through ductwork from Silver Lake to the San Gabriel Valley. He picked up his HVAC fundamentals at Los Angeles Trade-Technical College before building Elite Air Duct Cleaning into a company where the owner still runs every job — not a dispatcher, not a rotating subcontractor.
In Citrus, that matters more than it might in flatter terrain. The foothill position here means Lennox systems face a triple load: extreme attic heat cycling, Santa Ana wind infiltration, and recurring wildfire smoke events that don’t reach valley-floor communities with the same intensity. We’ve cleaned ducts on Michael Avenue in the Citrus Highlands tract, on original 1960s ranch homes with ML193UH furnaces, and on newer Elite Series installs where the flex-duct was already cracking from heat embrittlement. Our Rotobrush and Nikro systems — the same class of tools used in commercial remediation — let us clean aggressively without damaging aging fiberglass liner or dislodging brittle flex connections.

Common Lennox Air Duct Cleaning Problems We Solve in Citrus
- Sheet-metal trunk mastic failure in 1950s–1970s ranch homes. Citrus was built on former orchard land, and those original sheet-metal supply trunks routed through unconditioned attics have endured decades of 150°F+ summer heat. The mastic sealant cracks, allowing unfiltered foothill air — dust, chaparral particulates, ash — to bypass your filter entirely. We reseal with high-temperature aftermarket mastic that outperforms original specs.
- Flex-duct collapse and dislodgement from Santa Ana wind pressure. The Santa Ana events that funnel through the San Gabriel Valley hit Citrus harder than valley-floor cities. We’ve found flex-duct connections in cramped foothill attics collapsed under their own weight or blown loose at the collar, creating debris traps that standard cleaning misses without video inspection first.
- Merit Series fiberglass duct board delamination. The ML193UH and similar Merit systems in older Citrus homes often have original fiberglass duct board. Aggressive vacuuming without pre-sealing releases glass fibers into living spaces. We inspect first, seal compromised sections, and adjust our Rotobrush contact pressure to match the material condition.
- Post-fire evaporator coil ash embedding. After Angeles National Forest fires, Lennox systems that ran during smoke events pull ash deep into coil fins. The coil face looks clean from the outside; inside, it’s a gray mat reducing capacity by 20% or more. We chemical-clean with Lennox-compatible alkaline degreaser — not the all-purpose foams that corroze aluminum.
- Heat-embrittled flex-duct liner cracking. Citrus sits in a heat-island bowl where summer attic temperatures regularly exceed 150°F. The plasticizers in Lennox flex-duct liner degrade within 5–7 years, causing embrittlement and longitudinal cracking that mechanical cleaning can’t repair. We’ll show you the scope footage and recommend replacement when patching is a waste.
Lennox Service in Citrus: What Local Conditions Mean for Your Equipment
Citrus sits at the immediate base of the Angeles National Forest in the San Gabriel foothills, and that geography creates a service pattern we don’t see in West Covina, Downey, or even Azusa. Wildfire smoke and ash from mountain fires get pulled directly into home air handlers — especially homes with north-facing or rooftop intakes that face the slope. After the Eaton Fire and similar events, we’ve developed a recurring “post-fire callback” rhythm: homeowners in the Citrus Highlands tract and similar neighborhoods call two weeks after the smoke clears, reporting that their Lennox system still smells like a campfire every time the fan kicks on.
Here’s what we typically find. The supply plenum — that sheet-metal box right above your furnace — has a visible ash layer. The evaporator coil face carries a smoky film that household filters never caught because the ash came in through attic breaches, not the return grille. In one 1965 ranch on Michael Avenue, we pulled a 1/4-inch layer of gray ash from a Lennox ML193UH supply trunk and found the coil fins packed tight. The homeowner had run the system continuously during the fire event, thinking the filter would handle it. Standard filter media doesn’t stop what enters through cracked mastic or a dislodged flex collar.
For Lennox owners in Citrus, this means duct cleaning isn’t a once-every-ten-years maintenance item. It’s a post-fire necessity, a heat-cycling inspection point, and a Santa Ana-season check — all shaped by foothill geography that flatland communities simply don’t face.
Lennox Models & Products We Service in Citrus
We work on the full residential Lennox lineup, with particular familiarity for the systems common in Citrus’s housing stock:
- Merit Series: ML193UH furnaces, ML14XC1 air conditioners — the workhorses in 1960s–1980s ranch homes with original ductwork that needs careful handling.
- Elite Series: EL296UHV variable-speed furnaces, EL18XPV heat pumps — newer installs where flex-duct cracking from attic heat is the emerging issue.
- Signature Series: SL280UH, SL18XC1 — high-efficiency systems with tighter coil fin spacing that trap foothill dust and ash more readily.
We stock OEM Lennox motors, control boards, and ignitors for same-day repair when needed. For duct materials and sealants, we use aftermarket products — high-temperature mastic, aluminum tape rated for 200°F, and Abatement Technologies HEPA containment — that meet or exceed original specs without the OEM markup. We’re honest about the line: we’ll clean and seal what can be saved, and we’ll tell you when a 50-year-old sheet-metal trunk with multiple failure points should be replaced rather than patched again.
Lennox Service Pricing in Citrus
Most complete Lennox duct cleaning jobs in Citrus fall between $380 and $720, depending on system size, accessibility, and condition. Here’s how that breaks down:
- Standard residential duct cleaning (single system, up to 12 vents): $380–$480
- With video inspection and evaporator coil cleaning: $520–$620
- Post-fire deep clean with HEPA vacuuming, coil chemical clean, and supply trunk seal: $580–$720
- Duct sealing (mastic repair, collar reattachment, flex replacement per run): $180–$340 additional
What drives cost? Attic accessibility in those cramped 1960s ranch spaces, the extent of mastic failure we find, and whether we’re dealing with standard dust loading or embedded wildfire ash requiring chemical coil treatment. Every estimate starts with a free inspection — we’ll scope the trunk, check the coil face, and give you a fixed price before any work begins. Call (866) 359-7544 to schedule; estimates are free and Matthew Gonzalez handles them personally.

FAQs — Lennox Air Duct Cleaning in Citrus
No — we’re an independent service provider with no manufacturer affiliation. We don’t perform warranty work or represent Lennox officially. What we offer is 11 years of hands-on experience with Lennox equipment in Citrus’s specific foothill conditions, plus OEM-compatible parts and honest assessment of what your system actually needs. For warranty claims, contact Lennox directly; for duct cleaning, repair, and sealing that accounts for local heat and wildfire exposure, call us at (866) 359-7544.
Within two weeks of the air clearing, especially if you ran your system during the fire event. Ash embeds in evaporator coil fins and supply plenums within days, and the longer it sits, the more it works into porous duct liner. We prioritize post-fire calls in Citrus because we’ve seen the pattern: delay it, and you’re looking at coil replacement instead of chemical cleaning. Call (866) 359-7544 — we can usually inspect same-day.
Yes, with the right pre-inspection and technique. We video-scope first to identify delaminated sections, seal any compromised areas with encapsulant before mechanical contact, and use reduced brush pressure on our Rotobrush system. Original Merit Series duct board in Citrus homes is often brittle from attic heat cycling, so we adjust our approach accordingly — never one-size-fits-all. If the liner is too far gone, we’ll show you the footage and discuss replacement options.
Three local factors: Santa Ana winds funnel directly through the San Gabriel Valley gap and hit Citrus with higher particulate velocity; your attic likely hits 150°F+ in summer, degrading duct seals that West Covina’s milder attic temperatures preserve; and wildfire ash from the Angeles National Forest above town introduces fine particulate that valley-floor communities don’t receive in the same concentration. Your system isn’t failing — it’s fighting a harder local battle. Call (866) 359-7544 and we’ll identify the specific infiltration points.
Yes — duct sealing is one of our five core services, and it’s often the most cost-effective improvement for Citrus homes. We remove degraded mastic, prep the metal surface, and apply new high-temperature sealant rated for extreme attic conditions. For cracked flex-duct collars, we reattach with mechanical fasteners plus sealant, not just tape. The goal is stopping unfiltered foothill air from bypassing your filter entirely. Call (866) 359-7544 for an inspection and exact quote — estimates are free.
Our focus is residential and light commercial — small office buildings, retail suites, multi-family properties with standard split systems. We don’t service large rooftop package units or industrial Lennox installations. If you’re unsure whether your system fits our scope, call (866) 359-7544 with the model number and we’ll tell you straight.
