Lennox HVAC in Tujunga, CA | Meridian Heating & Air Los Angeles
Independent Lennox service in Tujunga typically runs $175–$765 for repairs and $95–$235 for tune-ups, with most calls completed same day. What sets our work apart here is how we size the fix against Tujunga’s real conditions — the 1,500-foot elevation, canyon wind exposure, and post-fire ash loads that most flat-Valley techs never account for. We’ve been servicing Lennox systems across the 91042 and 91043 zip codes for nearly two decades, and Anthony Moreno still leads the service calls himself. Call (877) 454-5066 for a free estimate.
Why Tujunga Residents Choose Us for Lennox Service
We’ve worked on Lennox equipment long enough to know the difference between a Lennox sales & service pitch and actual field knowledge. Anthony Moreno learned the trade at Los Angeles Trade-Technical College, where a refrigeration instructor told him on day one that the only way to understand HVAC was to get your hands dirty before you got your certification. He’s never forgotten that. Nineteen years later, he’s still the one climbing into Tujunga attics to trace a refrigerant leak or pulling a heat exchanger for inspection.
Our customers in Tujunga aren’t looking for a rotating crew of subcontractors. They’re looking for someone who recognizes that their 1950s ranch on Tujunga Canyon Boulevard has ductwork sized for a wall furnace retrofit, not a modern Lennox variable-speed system. We stock OEM-compatible Lennox parts — pressure switches, ignitors, control boards, TXV valves — because we’ve seen what happens when a generic replacement meets Tujunga’s hard-start heating season. Anthony shows up on the job. That’s not marketing; it’s how we’ve earned 286 reviews at 4.8 stars.
Common Lennox HVAC Problems We Solve in Tujunga
- Cracked heat exchangers in Lennox G40 and G50 series furnaces. Tujunga’s winter hard frosts push these mid-efficiency units through more heating cycles than flat-Valley equivalents. We inspect with combustion analyzers and borescopes, not just visual checks, because a cracked exchanger in a foothill home with tight construction can spike CO risk fast.
- Compressor overload in Lennox XC14 and XC16 condensers. The Santa Ana winds funnel straight through Big Tujunga Canyon, packing outdoor coils with dust and debris. High-ambient operation plus fouled coils equals head pressure spikes. We clean coils to manufacturer spec and check amp draw on startup — not just hose it off and hope.
- Failed capacitors and contactors in Lennox Merit series systems. Post-fire ash events from the Verdugo and San Gabriel slopes above Tujunga create conductive film on electrical components. Standard quarterly maintenance misses it. We’ve replaced contactors that looked fine but were arcing internally from ash infiltration.
- Undersized ductwork choking Lennox variable-speed air handlers. Tujunga’s post-WWII ranches and bungalows often have 6-inch supply trunks retrofitted from original wall-furnace runs. A Lennox SLP98V or EL296V needs proper static pressure to stage correctly. We measure total external static pressure and redesign duct segments where needed, not just blame the equipment.
- Dirty evaporator coils in Lennox CBX32MV air handlers. The diurnal temperature swings in Tujunga — 30°F-plus in spring and fall — mean systems short-cycle between heating and cooling modes. Condensate doesn’t fully drain, microbial growth takes hold, and airflow drops off within a season. We pull and clean coils when indicated, not just spray foaming cleaner upstream and call it done.
Lennox Service in Tujunga: What Local Conditions Mean for Your Equipment
Tujunga sits at the mouth of Big Tujunga Canyon at roughly 1,500–2,000 ft elevation, and that geography creates a maintenance reality you won’t find in Van Nuys or Panorama City. The 2009 Station Fire and subsequent burn cycles in the foothills above have left a legacy of fine mineral ash that standard maintenance schedules simply don’t address. Technicians working Tujunga regularly find condenser coils packed with ash that blew down from the slopes during Santa Ana events — material so fine it passes through standard mesh screens and cakes between fin rows. For Lennox service in Shadow Hills and nearby foothill communities, this same ash issue means an XC20 or SL18XC1 can run at reduced capacity for months before anyone notices the efficiency drop. We’ve made annual post-fire-season coil cleaning a standard recommendation for our Tujunga customers, not because we’re selling something unnecessary, but because we’ve measured the performance recovery: 15–20% capacity restoration on systems that “passed” a basic visual inspection. If the system isn’t working right, something is wrong — and it’s usually fixable once you actually look at it.
Lennox Models & Products We Service in Tujunga
We work on your brand — and Lennox is one of nine major lines we carry deep experience on, alongside Carrier, Trane, Goodman, Rheem, York, Daikin, Bryant, and American Standard. In Tujunga, we most commonly service the Dave Lennox Signature Collection (SLP98V, SL280V, XC25, XC21), Elite Series (EL296V, EL280, XC16, XC14), and Merit Series (ML180E, ML14XC1, 14ACX). For heat pumps, the XP25 and XP20 see regular calls in the foothills where dual-fuel makes sense given the heating load.
We stock OEM-compatible control boards, ignitors, flame sensors, pressure switches, and TXV valves for fast turnaround on Tujunga calls. When a proprietary Lennox part is required — certain variable-speed blower modules, for instance — we source through authorized distribution with next-day availability rather than substituting a universal part that compromises system communication. Our truck inventory covers the failure modes we actually see here, not a generic national catalog.

Our free estimate includes a full diagnostic with digital refrigerant pressure readings, combustion analysis where applicable, and static pressure measurement. No guesswork. Call (877) 454-5066 to schedule — estimates are free, and most Tujunga calls run same day.

FAQs — Lennox HVAC in Tujunga
No. Meridian Heating & Air Los Angeles is an independent Lennox service provider, not a factory-authorized dealer. We’re experienced on Lennox equipment through 19 years of field work, not through a franchise agreement. That independence means we recommend what’s actually needed for your system, not what’s on a manufacturer’s promotional calendar.
We use OEM-compatible parts that meet or exceed Lennox specifications, and we source proprietary components through authorized distribution when required. For common failures — ignitors, flame sensors, capacitors — we match the OEM part number. For obsolete Lennox components, we specify replacements that maintain system safety and communication protocols, not universal substitutes that drop error codes.
Most residential repairs run 1.5 to 3 hours. Tujunga’s hillside access and tight attic spaces can add time, but we stock the parts that fail most often here. If you’re without heat during a hard frost or AC during a Santa Ana push, we prioritize the call. Call (877) 454-5066 — we’ll give you a realistic arrival window, not a four-hour guess.
We service the full Lennox residential and light commercial range: Dave Lennox Signature, Elite, and Merit series furnaces and air conditioners; Lennox heat pumps including XP25, XP20, and XP14; air handlers like the CBX32MV and CBX27UH; and mini-split systems. If it’s Lennox and it’s in Tujunga — or nearby areas where we offer Lennox in La Crescenta-Montrose — we’ve likely worked on it or its direct predecessor.
For Lennox systems under 12 years with a repair under $600, repair usually wins. Above $800 on a unit past 15 years, replacement economics improve fast — especially given Tujunga’s heating load and the efficiency gains in current Lennox variable-speed equipment. We don’t sell equipment on every call; we’ll tell you straight when a repair is throwing good money after bad. Call (877) 454-5066 for an exact assessment — estimates are free.
