Lennox HVAC in Van Nuys, CA | Redwood Heating & Air San Diego
We provide independent Lennox service across Van Nuys — no dealer affiliation, just 13 years of factory-trained diagnosis on Merit, Elite, and Signature systems. The single thing that separates our work here is how we account for the San Fernando Valley’s thermal punishment: a Lennox compressor on a 105°F Van Nuys afternoon sees discharge pressures 20% higher than the same unit in nearby Burbank, so our spring tune-ups target high-static alerts that generic Southern California checks miss.

Why Van Nuys Residents Choose Us for Lennox Service
Gregory Hahn founded this company and still leads every technical decision. He grew up in Mira Mesa, trained in HVAC and refrigeration technology at Miramar College, and spent 13 years building Redwood Heating & Air into a shop where the Master Technician is on the truck, not in a corporate office. That matters in Van Nuys because your Lennox system isn’t failing generically — it’s failing specifically from Valley-floor heat cycling, post-Northridge duct degradation, or a defrost board cooked in a 150°F attic, the same way we see with Lennox repair in North Hills. We track factory service bulletins for the SLP98V, ML14XC1, and XC20 and apply them during repairs without any manufacturer affiliation.
Our senior technicians average 14 years working exclusively on Lennox split systems in the San Fernando Valley heat sink. We stock OEM Lennox compressors, heat exchangers, and electronic controls for warranty compliance, plus quality aftermarket capacitors and contactors to keep older Merit systems running without the factory markup. From a single mini-split to a full commercial system, we diagnose right the first time. If Gregory wouldn’t put it in his own house, he’s not recommending it for yours.
428 verified reviews, 4.6 stars, 13 continuous years — that track record outlasts most local HVAC startups and one-truck operations.
Common Lennox HVAC Problems We Solve in Van Nuys
- ML14XP1 defrost board failure from attic heat. The defrost control module sits in an attic that hits 150°F in Van Nuys summer. We relocate it to the return plenum as a permanent fix instead of replacing the same cooked board every three years.
- Elite TC16 evaporator coil leaks accelerated by continuous high-side pressure. 115°F afternoons push refrigerant pressures the unit wasn’t tested for. Coils that should last 15 years fail in 8–10 here. We pressure-test, verify superheat, and replace with OEM-matched coils sized for actual Valley loads.
- SLP98V secondary heat exchanger rust from trapped condensate. Oversized furnaces crammed into small 1950s attic chases common on Vanowen Street can’t vent properly. A flow check and venting adjustment solves what looks like a heat exchanger replacement.
- XC20 compressor contactor pitting from daily thermal cycling. June through September, your contactor opens and closes hundreds of times more than in coastal zones. We catch pitting during spring tune-ups before it becomes a no-cool call on a 108°F day.
- Low charge readings caused by separated flex-duct boots, not actual refrigerant loss. Post-Northridge retrofits done with foil tape in 1994–1995 have long since failed. A system that tests low is often just pumping conditioned air into a 150°F attic.
Lennox Service in Van Nuys: What Local Conditions Mean for Your Equipment
Van Nuys sits in the deepest interior of the San Fernando Valley heat sink, geographically cut off from coastal marine cooling by the Santa Monica Mountains. It routinely hits 105–115°F on days when Santa Monica is 72°F — a 30°F+ swing on the same afternoon. Every sizing, ductwork, and equipment-longevity decision here must be calibrated for that Valley-floor thermal punishment, not for generic Southern California conditions.
For Lennox owners, this means your compressor discharge pressure runs 20% higher than design spec on the hottest days. The ML14XC1 and XC20 units we service on Ventura Boulevard and along the 91405–91406 corridors regularly trigger high-pressure switches that would never trip in Lennox in Sherman Oaks or Burbank. We don’t just reset the switch. We measure static pressure, verify condenser coil cleanliness against the dust load from nearby construction, and check whether the original installer sized for 95°F design temperature instead of Van Nuys reality. The 1994 Northridge earthquake rattled flex-duct connections throughout local housing stock; on a July afternoon in the Haskell Hills neighborhood, we found a 2014 Merit ML14XC1 reading low on charge. A rookie would add refrigerant. We pulled the attic hatch first and discovered a boot separated from the flex duct, a post-Northridge retrofit failure, pumping 52°F air into a 150°F attic. We sealed the connection, verified superheat, and the system recovered without adding a single ounce of R-410A.
Lennox Models & Products We Service in Van Nuys
We service the full Lennox residential line with factory-trained fluency: Lennox sales & service covers Merit series ML14XC1 air conditioners and ML14XP1 heat pumps, Elite series TC16 and SC16 split systems, and Signature collection SLP98V variable-capacity furnaces paired with XC20 precision comfort air conditioners. For Van Nuys homes originally built without central AC — the 1950s–1970s stucco tract houses that dominate here — we also handle add-on duct system integration where attic routing pushes equipment harder than intended.
OEM Lennox parts for compressors, heat exchangers, and electronic controls ship to our local warehouse for 24–48 hour turnaround on most Van Nuys calls. Capacitors and contactors we stock direct from verified aftermarket suppliers, because a 20-year-old Merit system doesn’t need factory-markup parts to run another five years reliably.

FAQs — Lennox HVAC in Van Nuys
Probably not. In Van Nuys, this pattern usually means separated flex-duct boots from post-Northridge retrofits, or a condenser coil choked with Valley dust. We check airflow before condemning the compressor. Call (844) 875-9451 and we’ll diagnose it properly.
If the coil is original and leaking, replacement makes sense — the TC16 coil in Van Nuys conditions typically fails at 8–10 years, not 15. If it’s a contactor or capacitor issue, repair is economical. We’ll give you both numbers and our honest recommendation. Call (844) 875-9451 for a free assessment.
Not without checking the ductwork first. These houses were built without central AC, and add-on attic ducts in Van Nuys regularly can’t move 1200 CFM through 6-inch flex. We do a Manual J load calculation and static pressure test before specifying equipment. Call (844) 875-9451 to schedule.
It could be, but in Van Nuys we more often find secondary heat exchanger rust from condensate trapped by poor venting in small attic chases. A flow check costs far less than a heat exchanger replacement and tells us which problem you actually have.
Usually yes. Garage conversions on narrow Van Nuys lots rarely have attic pathing for ductwork, and a Heat Pump & Mini Split in Van Nuys avoids the 150°F attic penalty entirely. We can run a ducted Lennox system if the structure allows, but mini-split efficiency in this climate often wins.
