Lennox HVAC in West Hills, CA | Stonegate Heating & Air California
We provide independent Lennox service across West Hills, not as a factory-authorized dealer, but as technicians who know these systems from sixteen years of hands-on repair and installation in the 91307 and 91308 ZIP codes. The one thing that makes our Lennox work here different: we understand how West Hills’s 150°F attic temperatures and Woolsey Fire rebuild split have created two completely different equipment populations within the same neighborhood, and we diagnose accordingly. Call (855) 467-1888 for a free estimate.
Why West Hills Residents Choose Us for Lennox Service
We’ve worked on Lennox equipment in West Hills since 2004, and we also handle Lennox service in Woodland Hills. That’s long enough to know which ranch homes off Fallbrook Avenue still run original Merit 13ACD condensers from the 1980s, and which hillside rebuilds near the Santa Susana Pass have new SL28XCV variable-speed systems with R-32 charge.
Our Lennox sales & service approach is straightforward: OEM parts for compressors, control boards, and heat exchangers; quality aftermarket for capacitors and contactors when it makes sense. We don’t upsell equipment you don’t need. Jason Trent, our owner and Field Supervisor, still shows up on the bigger jobs himself. He grew up in the San Fernando Valley, took his HVAC training at Los Angeles Trade-Technical College, and spent enough summers without reliable AC to know exactly what a failed system feels like in July.
Nearly 500 reviews at 4.7 stars back up what we do. We’re certified on nine brands, so if your West Hills home has a mixed system or you’re switching from another manufacturer, we won’t send you elsewhere.
Common Lennox HVAC Problems We Solve in West Hills
- Evaporator coil micro-leaks on aging Merit 13ACD units. These 10- to 15-year-old systems are common in valley-floor ranch homes. West Hills attic temperatures routinely hit 150°F, accelerating metal fatigue at the coil’s copper-aluminum joints. We pressure-test, locate the leak zone, and advise honestly: if the system’s past twelve years, replacement usually wins in this climate.
- Variable-speed blower motor failures on SL28XCV systems. The control board capacitors degrade faster when attic heat exceeds manufacturer design specs. We’ve replaced three in West Hills this past summer alone, all in ranch homes with original access panels and no attic ventilation upgrades.
- Scroll compressor valve failures on XP25 heat pumps. Santa Ana winds funnel through the Santa Susana passes in autumn, carrying fine dust that scores valve plates just as cooling loads spike from 90°F+ days. The XP25’s variable-capacity modulation works hard in these conditions, and rapid cycling compounds the wear.
- Collapsed flex-duct liners mimicking equipment failure. At a 1973 ranch home on Kittridge Street, the homeowner reported “no cooling” from their original Merit 13ACD. Our tech found the flex-duct supply run to the master bedroom had completely collapsed, its inner liner detached near the air handler from years of 150°F attic exposure. We replaced the duct run with R-8 insulated flex and a Lennox OEM transition, restoring 100% airflow without touching the condenser.
- High-pressure switch trips on autumn afternoons. Santa Ana heat spikes hit when homeowners still have their thermostats set for September mildness. The condenser can’t shed heat fast enough, especially if debris from dry Santa Ana gusts has packed the coil fins.
Lennox Service in West Hills: What Local Conditions Mean for Your Equipment
West Hills is split into two distinct service zones by the 2018 Woolsey Fire burn area. Homes rebuilt after the fire have modern Title 24-compliant ductwork and equipment, while the original 1960s-80s ranch homes on the valley floor still run original undersized systems with brittle attic ductwork. The service approach differs completely between streets like Shoup Avenue and those near the Santa Susana Pass.
For Lennox owners, this split matters in concrete ways. A rebuilt home’s SL28XCV with sealed ductwork and proper Manual J sizing runs at design efficiency. But a valley-floor ranch with a 13ACD connected to collapsed flex duct? The compressor runs continuously, pressures go abnormal, and homeowners blame the equipment when it’s the delivery system. We’ve learned to check airflow first on Fallbrook Avenue calls. The system will tell you what’s wrong — you just have to know how to listen.
This also affects replacement economics. In rebuilt zones, we can spec Lennox equipment to current Title 24 standards with confidence the duct system will support it. In original ranch zones, we often quote duct repair alongside equipment replacement, because new Lennox capacity on failed delivery is wasted money.

We work on the full Lennox residential and light-commercial line: Merit Series 13ACD units still running in older West Hills tracts; Elite Series EL16XC1 two-stage systems; Signature Series SL28XCV variable-capacity units with R-32 transition; and XP25 variable-capacity heat pumps. We also handle mini-split installations for hillside homes where central duct retrofit isn’t practical.
Our parts stock for West Hills includes common Lennox OEM control boards, blower motors, and TXV assemblies, plus R-410A and R-32 recovery equipment. We don’t carry every factory part, but we know which West Hills distributors have same-day availability. For routine repairs, we’ll recommend quality aftermarket capacitors and contactors when the cost difference matters and reliability doesn’t suffer.

FAQs — Lennox HVAC in West Hills
Collapsed flex duct in the attic is the most common cause we find in 1960s-80s West Hills ranch homes. Attic temperatures destroy duct mastic and detach inner liners over time. The condenser runs but cooled air never reaches the rooms. We inspect duct integrity before blaming the equipment. Call (855) 467-1888 for a free diagnostic.
You’re not legally required to replace an R-22 system. We can recover and recharge existing R-22, though reclaimed refrigerant costs have risen significantly. If your Merit 13ACD has other age-related issues, we’ll give you honest numbers on repair versus replacement with current R-410A or R-32 equipment.
Rebuilt homes have Title 24-compliant duct sealing and insulation, so they can support higher-efficiency variable-capacity Lennox systems like the SL28XCV, similar to what we install for Lennox service in Calabasas. Original ranch homes often need duct repair or upsizing before similar equipment makes sense. We assess the whole system, not just the box outside.
For hillside rebuilds with limited attic space or room additions without duct access, a Lennox mini-split install — like those we do for Lennox service in Chatsworth — often outperforms trying to extend central ductwork. We zone each unit independently, which also helps during Santa Ana heat spikes when you need targeted cooling, not whole-house operation. Call (855) 467-1888 to discuss layout and pricing.
Santa Ana winds raise outdoor temperatures rapidly while carrying dust that clogs condenser fins. The XP25 and EL16XC1 both have protective high-pressure cutouts that trip before damage occurs. We clean coils, verify fan operation, and sometimes recommend a compressor hard-start kit if electrical sag compounds the thermal load.
