Lennox HVAC in Calabasas, CA | Northstar Heating & Air San Francisco
Independent Lennox repair in Canoga Park and across Calabasas typically runs $175–$765 for repairs and $95–$235 for tune-ups, with most calls completed same-day. What sets our Lennox work apart here is Daniel Okafor’s direct, hands-on experience with the split housing stock that defines this market: post-Woolsey rebuilds with Title 24 heat pump systems alongside aging 1990s tract homes still running original R-22 units. We’re not a Lennox dealer or authorized representative — we’re an independent, owner-operated shop that services every major brand including Lennox, and we bring 10 years of field experience plus a 4.9-star rating across 357 reviews to every job.

Why Calabasas Residents Choose Us for Lennox Service
Daniel Okafor grew up in San Francisco’s Excelsior District and learned the trade at City College of San Francisco, where the HVAC program drilled load calculations and refrigeration theory into students who would spend their careers solving problems the textbooks only half-predict. That background matters in Calabasas, where a 4,000-square-foot home in The Oaks can have a Lennox XC25 communicating with a completely different control architecture than a rebuilt hillside property off Mulholland with a Lennox heat pump and ERV tied to Title 24 compliance.
We don’t dispatch crews. Daniel personally handles diagnostics and repair on Lennox systems, which means the same person who reads your pressures and amp draws is the one whose reputation is tied to the outcome. We’re certified to work on 9 major HVAC brands — Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard — so there’s no “we’ll have to call someone else” runaround when your Lennox sales & service needs get complicated. For urgent situations, our emergency HVAC availability means you aren’t waiting days for a callback while Santa Ana winds push your attic air handler past its thermal limit.
Common Lennox HVAC Problems We Solve in Calabasas
- High-head-pressure lockouts on XC/XP heat pumps. Calabasas’s Santa Ana events spike ambient temperatures past 100°F while humidity crashes into single digits. Lennox outdoor units on canyon-adjacent properties in 91302 see refrigerant pressures climb to compressor-protect thresholds within hours. We recover, measure, and recharge to exact Lennox spec — not “close enough.”
- Communicating system faults between SLP98V furnaces and iComfort thermostats. The large-footprint homes in Calabasas Park Estates often have long low-voltage runs through unconditioned attics. Heat expansion degrades signal integrity. Daniel has traced these faults to corroded splices that franchise techs missed because they didn’t stay on the job long enough to follow the full wire path.
- ERV and fresh-air ventilation imbalances in post-Woolsey rebuilds. Title 24 requires mechanical ventilation, but Lennox ERV units in hillside rebuilds near Malibu Canyon get fouled with ash and particulate every fire season. We clean, balance, and verify airflow against design specs — not guesswork.
- TXV hunting and superheat drift on legacy R-22 systems. Hundreds of Calabasas homes still run 1990s–2000s Lennox units with piston or early TXV metering. The thermal bowl effect — cool marine mornings, then rapid afternoon heating — causes these systems to hunt between modes. We measure subcooling and superheat across the full cycle, not at one static point.
- Attic air handler motor and capacitor failures. Unconditioned attics in Calabasas’s gated communities absorb extreme radiant heat. Lennox air handlers with PSC motors or single-stage blowers run at constant speed, overheating capacitors and degrading bearings. We upgrade to OEM-spec replacements that match Lennox’s original design tolerances.
Lennox Service in Calabasas: What Local Conditions Mean for Your Equipment
The 2018 Woolsey Fire destroyed hundreds of hillside and canyon-edge homes in Calabasas’s 91302 zip code, triggering a wave of rebuilds that had to meet California’s updated Title 24 energy codes. This created a housing market split that no neighboring city replicates at this scale: newly rebuilt, code-compliant hillside homes with ducted heat pumps and fresh-air ventilation, sitting alongside intact 1980s–2000s gated-community tract homes in The Oaks and Calabasas Park that are still running aging R-22 or early R-410A Lennox systems. For a Lennox technician, this means two completely different service paradigms on opposite sides of the same valley. A rebuilt home off Mulholland might have a Lennox XP25 heat pump with an ERV and zoning dampers — equipment that demands digital manifold gauges, airflow hood verification, and knowledge of Title 24 commissioning requirements. Three miles east in Calabasas Park, a 1998 Lennox G26 furnace with a cracked heat exchanger needs combustion analysis and a conversation about replacement timing that accounts for the homeowner’s actual usage patterns, not a generic depreciation schedule. Daniel has worked both scenarios repeatedly, and the difference in approach is not something you learn from a brand certification seminar.
Lennox Models & Products We Service in Calabasas
We service the full Lennox residential and light-commercial lineup: Signature Collection variable-capacity systems including the XC25 and XP25; Elite Series two-stage units like the XC21 and SL18XP1; Merit Series single-stage workhorses including the 14ACX and ML180 furnace; and Dave Lennox Signature Collection furnaces with modulating gas valves. For Heating & Furnace in Calabasas, we stock OEM Lennox ignitors, pressure switches, and control boards for same-day resolution on common failures. We don’t substitute aftermarket parts that void your remaining warranty or fail to match Lennox’s control algorithms. For communicating systems, we carry the proprietary iComfort interface tools that independent shops often lack. If your Calabasas home has a Lennox heat pump installed post-Woolsey, we have the refrigerant profiles and charging charts for R-410A and the newer R-32 transitions appearing in 2024–2025 equipment.
Lennox Service Pricing in Calabasas
| Service | Price Range |
|---|---|
| Lennox AC Repair | $175–$765 |

| Lennox AC Installation | $4,130–$8,850 |
| Lennox Tune-Up / Maintenance | $95–$235 |
What drives cost? Accessibility matters in Calabasas. Attic air handlers in 6,000-square-foot homes with steep roof pitches take longer to reach than ground-level package units. Communicating systems require diagnostic time that single-stage units don’t. Post-Woolsey rebuilds with integrated ERV and zoning add complexity. Our free estimate includes a full system inspection, written findings, and prioritized options — no pressure, no mystery. Call (855) 600-3322 for exact pricing on your specific Lennox system.

FAQs — Lennox HVAC in Calabasas
No. Northstar Heating & Air San Francisco is an independent service provider, not manufacturer-affiliated or authorized. This means we can service your Lennox equipment without steering you toward Lennox-only replacement options, and we work on 9 major brands including Lennox, Goodman, Trane, and Carrier. For honest diagnostics on an aging Lennox system in Calabasas, or for Lennox service in Las Flores, call (855) 600-3322.
We use OEM Lennox parts for any component that affects warranty coverage, system communication, or safety — control boards, pressure switches, ignitors, TXVs, and ERV cores. Aftermarket substitutes save a few dollars upfront but often fail to match Lennox’s voltage tolerances or airflow algorithms, especially on variable-capacity and communicating systems common in newer Calabasas rebuilds.
Most residential Lennox repairs in Calabasas finish within 2–4 hours. Simple capacitor or contactor replacements on accessible attic units run shorter. Full refrigerant recoveries on heat pumps with hard-to-reach condensers in hillside lots, or ERV balancing in post-Woolsey rebuilds, can extend to a full day. We give you a time estimate after inspection, not a guess over the phone.
Every current and recent-discontinued Lennox residential line: Dave Lennox Signature Collection (SLP98V, XC25, XP25), Elite Series (XC21, SL18XP1, EL296V), Merit Series (14ACX, ML180, ML14XC1), and all associated heat pumps, air handlers, ERVs, and iComfort controls. We also service light-commercial Lennox rooftop units common in Calabasas retail and office spaces.
Repair typically runs $175–$765; full replacement starts at $4,130. For a 15-year-old Lennox R-22 system in a Calabasas Park tract home, replacement often makes sense given refrigerant costs and efficiency gains. For a 6-year-old Lennox XP25 in a post-Woolsey rebuild, repair is usually the smarter play. Daniel personally evaluates your system’s condition, your actual usage, and your home’s specific load requirements before recommending either path. Call (855) 600-3322 for a free, no-pressure assessment.
