Independent Lennox repair in Agoura Hills runs $150–$650 for most repairs, with full AC installations ranging $3,500–$7,500.

Why Agoura Hills Residents Choose Us for Lennox Service
We’ve worked on Lennox equipment in Agoura Hills since before the Woolsey Fire burned through the Santa Monica Mountains. Back then, the calls were typical for the Las Virgenes Valley: refrigerant leaks on 20-year-old Merit units, contactors failing after Santa Ana wind events, the usual canyon-climate wear. After November 2018, the nature of service calls changed. Homeowners in Lake Lindero and the Meadows started reporting blower motors seizing on perfectly maintained systems, evaporator coils leaking refrigerant slowly enough that the loss took months to notice. We traced it to fine ash drawn through return vents during the fire’s pressure events, a failure mode that doesn’t exist in Thousand Oaks or Calabasas.
Our Lennox sales & service approach is built on that field experience. Marcus Feldman, our owner and Service Manager, grew up in Woodland Hills where summer heat was serious business. He trained at Los Angeles Trade-Technical College, spent two decades on everything from R-22 dinosaurs to variable-speed heat pumps, and launched Crestview 19 years ago. He still runs service calls himself. That matters when you’re diagnosing whether a Lennox EL18XCV needs a $400 blower assembly or a full replacement. We’re not a franchise dispatching whoever’s available. We’re owner-managed, not outsourced, with 250+ reviews averaging 4.8 stars to show for it.
Your system, our specialty. We carry OEM Lennox parts for critical components and quality aftermarket options where they make sense. From emergency calls to commercial buildouts, if it says Lennox on the cabinet, we’ve probably repaired it in Agoura Hills.
Common Lennox HVAC Problems We Solve in Agoura Hills
- Blower motors seized by Woolsey Fire ash. The 2018 fire’s heat-driven pressure events pulled fine particulate through ductwork even in standing homes. We’ve found packed motor windings in Lennox units that appeared untouched from the street. The fix: replace the blower assembly and clean the evaporator with specialized degreasing solution to prevent repeat failure.
- Evaporator coils corroded by smoke residue. Ash and combustion byproducts create slow refrigerant leaks that surface years after the fire. A Lennox Merit 14ACX might cool fine in May and be flat by August. We pressure-test the coil, verify the leak location, and recommend OEM or quality aftermarket replacement based on unit age.
- Single-stage units short-cycling in canyon temperature swings. Agoura Hills sees 30–40°F overnight drops. A Lennox 14ACX sized for 100°F afternoons will short-cycle on mild evenings, chewing through contactors. We check load calculations and sometimes recommend two-stage or variable-speed upgrades for hillside homes.
- Condenser coil fin damage from Santa Ana debris. The Las Virgenes Valley corridor funnels wind-driven dust and vegetation into outdoor units. Bent fins on a Lennox EL18XCV reduce heat rejection and spike head pressure. We straighten or replace coils and recommend debris barriers for exposed installations.
- Fire-hardening compliance on post-Woolsey rebuilds. New construction in areas like Lake Lindero must meet Title 24 and Chapter 7A requirements. We’ve installed Lennox Signature Series SL28XCV systems with fire-compliant clearances and ignition-resistant exterior components that satisfy Agoura Hills building inspection.
Lennox Service in Agoura Hills: What Local Conditions Mean for Your Equipment
Agoura Hills sits entirely within California’s Very High Fire Hazard Severity Zone, and the 2018 Woolsey Fire’s heat-driven pressure events drew fine ash into ductwork even in standing homes, creating a hidden damage pattern—seized blower motors and corroded evaporator coils—that continues to surface in 91301 years later, a phenomenon absent in neighboring Oak Park and Thousand Oaks. For Lennox owners specifically, this means a unit that ran fine in 2017 might fail catastrophally in 2024 with no warning. The ash is alkaline and hygroscopic; it attracts moisture, accelerates copper corrosion, and packs into motor windings where standard air filters can’t reach it. We’ve replaced more evaporator coils in Agoura Hills tract homes than in any other city we serve, and the common thread is almost always a system that was running during the Woolsey Fire’s pressure events. If your Lennox is original to a 1970s–90s home and you’ve never had the ductwork inspected post-fire, that’s the first thing we’d check.
Lennox Models & Products We Service in Agoura Hills
We service the full Lennox residential lineup, with particular familiarity in Agoura Hills for these series:
- Merit Series: 14ACX air conditioners and 14HPX heat pumps. Common in original 1980s–90s tract homes. We stock contactors, capacitors, and aftermarket coils for fast turnaround.
- Elite Series: EL18XCV variable-speed AC and EL280E two-stage gas furnace. Popular in post-Woolsey rebuilds for efficiency compliance. OEM control boards and variable-speed blowers kept in stock.
- Signature Series: SL28XCV heat pump and SLP98V modulating furnace. High-end installs in newer construction. Full OEM parts support for warranty-adjacent repairs.
Our parts strategy is straightforward: OEM Lennox compressors and control boards for reliability, quality aftermarket coils and capacitors where they save money without compromising safety. We don’t guess at compatibility. If I wouldn’t put it in my own house, I’m not putting it in yours. Most common parts are on the van for same-day Agoura Hills service.

FAQs — Lennox HVAC in Agoura Hills
Yes. The fire’s pressure events pulled fine ash through return vents even in homes with zero structural damage. We’ve found seized blower motors and corroded evaporator coils in standing Agoura Hills homes years later. A duct inspection and coil pressure test will tell the story. Call (844) 560-6978 for a free diagnostic.
Agoura Hills requires Title 24 energy compliance and Chapter 7A ignition-resistant construction for rebuilds in the Very High Fire Hazard Severity Zone. We specify Lennox equipment with appropriate clearances, exterior ignition-resistant components, and documentation for building inspection. We handle the coordination.
No. We’re an independent Lennox service provider, not manufacturer-authorized or dealer-affiliated. We work on Lennox because we’ve repaired thousands of them and know the equipment cold, not because of a corporate relationship. Our 19 years and 250+ reviews stand on their own.
Probably, if it’s original equipment. The 30–40°F overnight temperature swings in the Las Virgenes Valley canyon microclimate mean a single-stage Merit 14ACX is oversized for mild evenings and undersized for 100°F Santa Ana days. A properly load-calculated variable-speed or two-stage replacement ends the short-cycling and cuts energy bills. For units under 10 years, repair might still make sense.
Yes. The City of Agoura Hills requires permits for HVAC replacements, with additional fire-hardening inspection for rebuilds in VHFHZ areas. We pull permits as part of our installation service and coordinate inspections so you’re not chasing paperwork. Call (844) 560-6978 to discuss your project timeline.
