Lennox HVAC in Westlake Village, CA | Crestview Heating & Air California
We provide independent Lennox service across Westlake Village’s 91359 and 91361 ZIP codes, with same-day availability for most calls. The one thing that makes our Lennox work here different: we’ve spent 19 years mapping the exact failure patterns of builder-spec Merit and Elite units in this city’s master-planned tracts, where 35–55 year old systems are failing in clusters. Call (844) 560-6978 for a free estimate.
Why Westlake Village Residents Choose Us for Lennox Service
Marcus Feldman still runs service calls himself. That’s not a slogan; it’s how Crestview Heating & Air California operates. After training in HVAC/R at Los Angeles Trade-Technical College and two decades in the field, he doesn’t trust a diagnosis he didn’t see with his own eyes. His daughter grew up watching him load refrigerant gauges before sunrise. That upbringing shows in how we work.
Our Lennox sales & service isn’t factory-authorized, and we don’t pretend it is. We’re independent. That means no corporate service tiers, no mandatory parts markups, and no technician who can’t explain why your EL18XCV threw a thermal lockout. We’ve diagnosed Lennox systems in Westlake Village since 2005, back when the original 1970s lakeside tracts were hitting their first replacement cycle. We know which homes off Lakeshore Drive still run R-22 Merit units from 2003, and which North Ranch properties have the EL280E furnaces that started showing up in the late 2000s.
We stock OEM Lennox compressors, coils, and control boards locally, plus premium aftermarket capacitors and contactors that match OEM specs. Your system, our specialty — whether it’s a 14ACX that won’t start or a Signature SL28XCV running at half capacity because attic flex duct has delaminated again. If I wouldn’t put it in my own house, I’m not putting it in yours.
Common Lennox HVAC Problems We Solve in Westlake Village
- Compressor thermal overload on Elite EL18XCV units during Santa Ana events. South-facing condensers in the Westlake Lake-adjacent streets bake 15°F above ambient when those dry winds hit in September. We’ve replaced three EL18XCV compressors on the same block in a single August. The fix isn’t just a new compressor; it’s verifying condenser placement, coil cleanliness, and whether the unit’s rated for the microclimate that tile roof creates.
- Failed flex duct connections at the air handler plenum. Attic spaces over 140°F under those clay tiles cook the mastic right off. In the 1970s–80s tracts off Triunfo Canyon Road, we routinely find 30%+ cooling loss with zero equipment fault. The Lennox air handler runs fine. The air never reaches the register.
- Capacitor failure on Merit 14ACX units in unshaded west-facing side yards. Near Lindero Canyon Road, reflected heat from tile roofs accelerates electrolyte evaporation. We’ve seen capacitors fail in 4–5 seasons instead of the expected 8–10. We use premium aftermarket replacements rated for 440V and higher temperature tolerance, or OEM when the homeowner wants the factory part.
- Evaporator coil pinhole leaks on R-22 Merit systems from 2001–2009 installs. Homes on Foxfield Drive and Ridgeway Court show this pattern consistently. Decades of thermal cycling in 95–105°F Conejo Valley attacks the copper. The system’s “low on refrigerant” again, and the leak search points to the coil every time.
- Variable-speed blower motor failure on Signature SLP98V furnaces. The ECM motors in these high-end units don’t like the voltage fluctuations that come with aging electrical panels in 1980s Westlake Village builds. We’ve replaced six in the past two years, always after the homeowner noticed uneven heating across zones.
Lennox Service in Westlake Village: What Local Conditions Mean for Your Equipment
Westlake Village’s 1968–1995 master-planned homes share near-identical flex-duct attic layouts — often R-4 or R-6 originally — so our techs have mapped the exact failure points. Duct boots pop off at the plenum in Sherwood Country Club estates. Mastic fails at the split transition in the North Ranch corridor. That uniformity makes static pressure testing a non-negotiable first step on every Lennox service call here, unlike in neighboring Thousand Oaks where Thousand Oaks Lennox service calls face more varied build eras and you might see metal duct, flex duct, and ductboard all on the same street.
On a 105°F September afternoon off Triunfo Canyon Road, we found a 2003 Lennox Merit 14ACX condenser in thermal lockout. A neighbor’s identical unit had failed the same way two weeks prior — both had outdoor fan motors pulling 20% above rated amps from clogged coils under a tile roof. We replaced both fan motors, added a hard-start kit, and cleaned the coils with foaming degreaser, restoring cooling in 90 minutes. For the second unit, we advised the homeowner that a replacement SL28XCV would cut peak-hour runtime by 40%.
The Conejo Valley’s climate punishes equipment harder than coastal LA. Summer hits 95–105°F, winter nights drop to the mid-30s, and those Santa Ana events in September through November concentrate stress on aging condensers. A Lennox system that might last 18 years in Santa Monica often shows its age at 14 here. We factor that into every repair-versus-replace conversation.
Lennox Models & Products We Service in Westlake Village
We work on every Lennox residential line you’re likely to find in Westlake Village:
- Merit series: 14ACX, 14HPX — the builder-grade workhorses still running in hundreds of original tracts. We stock capacitors, contactors, and replacement fan motors for same-day repair.
- Elite series: EL18XCV, EL280E — mid-tier units common in 2005–2015 renovations. The variable-speed EL18XCV needs careful diagnosis; we carry OEM control boards and scroll compressors.
- Signature series: SL28XCV, SLP98V — premium zoned systems in newer North Ranch and Sherwood builds. We handle the communicating controls and multi-stage staging these require.
OEM Lennox parts for compressors, coils, and control boards preserve factory reliability. For capacitors and contactors, we’ll show you the premium aftermarket option that matches OEM specs and the factory part, then recommend based on your system’s age and the repair cost relative to replacement. From emergency calls to commercial buildouts, we don’t turn away equipment because of its badge.
Lennox Service Pricing in Westlake Village
| Service | Price Range |
|---|---|
| AC Repair | $150–$650 |
| AC Installation | $3,500–$7,500 |
| Tune-Up | $80–$200 |
What drives cost? Compressor replacement on a Merit 14ACX hits the high end; a capacitor swap on the same unit lands near the low end. Installation pricing varies with home size — those 2,500–5,000 sq ft Westlake Village homes often need duct modification to support a high-SEER replacement, especially if the original flex runs through 140°F attics. Our free estimate includes static pressure testing, load calculation, and a written repair-versus-replace analysis. Call (844) 560-6978 to schedule; estimates are free, and we’re typically on-site same day for Westlake Village calls.

FAQs — Lennox HVAC in Westlake Village
Your system isn’t weaker; your attic is hotter. Westlake Village’s master-planned tracts used thinner flex duct and concentrated condensers in south- or west-facing side yards where tile roofs reflect heat. Lennox service in Agoura Hills and nearby areas face different conditions — Thousand Oaks has more varied build eras, better shading, and mixed duct types. The Santa Ana wind events here push ambient temperatures 10–15°F higher than the forecast. Call (844) 560-6978 and we’ll test your static pressure and condenser placement.
A 1989 Merit is likely 8–10 SEER; a new SL28XCV hits 28 SEER. In a 3,500 sq ft Westlake Village home with original R-4 duct, that upgrade typically cuts cooling costs 35–50%. We always test duct integrity first — new equipment on failing duct wastes money. Call (844) 560-6978 for a load calc and duct assessment; estimates are free.
Not necessarily full replacement, but modification is likely. We seal, insulate, and resize flex runs to match modern airflow requirements. The 1972 R-4 duct in your attic has probably delaminated; we’ll show you with a camera. A high-SEER variable-speed system needs precise static pressure — old duct won’t deliver. Call (844) 560-6978 for a duct evaluation with your estimate.
Yes, though some HOAs require visual screening or decibel compliance. The EL18XCV and SL28XCV both meet most Westlake Village HOA noise restrictions at 4 dB below the legal threshold. We handle the technical spec sheet for your architectural committee. Call (844) 560-6978 and we’ll coordinate with your HOA requirements.
We can’t process factory warranty claims as an independent provider. If your heat exchanger is under Lennox’s limited lifetime warranty, you’ll need a Lennox dealer for that specific part. We can diagnose the failure, provide a second opinion, and handle the replacement if you choose to pay out of pocket — sometimes faster than dealer scheduling. For non-warranty repairs, we’re fully equipped. Call (844) 560-6978 to discuss your options.
