Lennox HVAC in Century City, CA | Redwood Heating & Air San Diego
Lennox HVAC service in Century City typically runs $150–$700 for repairs and $3,500–$7,500 for new installations, with most calls completed same-day. What makes our Lennox work different here: we’re an independent service provider with 15+ years exclusively on Lennox equipment in high-rise commercial and luxury residential towers, not suburban split systems. The marine-layer humidity, aging pneumatic controls, and chilled water infrastructure of Century City’s 1960s–1980s building stock create failure patterns you won’t find in the Valley or the Westside.

Why Century City Residents Choose Us for Lennox Service
We’ve been inside enough Century City towers to know the difference between a standard Lennox callback and a real fix. Gregory Hahn founded this company and still leads every technical decision. He grew up in Mira Mesa patching ductwork in houses that had no business being that hot, trained in HVAC diagnostics at Miramar College, and has spent 13 years building Redwood Heating & Air into a shop that diagnoses right the first time.
That matters in Century City because your building’s HVAC isn’t a standalone unit — it’s a node in a central plant. When your Lennox Signature XC20 throws a fault code, the problem might be the condenser, the BAS integration, or a cooling tower sump choked with marine-layer algae. We’ve serviced nine major brands — Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard — so we don’t default to “replace everything” when the real issue is a $40 float switch or a drifting pneumatic actuator.
Our Lennox sales & service approach uses OEM parts for heat exchangers and coils, quality aftermarket for capacitors and contactors, and straight talk on whether repair or replacement makes sense. 428 verified reviews at 4.6 stars over 13 years. If Gregory wouldn’t put it in his own house, he’s not recommending it for yours.
Common Lennox HVAC Problems We Solve in Century City
- Pneumatic zone damper actuators failing from age. The 1960s–70s towers along Avenue of the Stars still run original pneumatic controls. A Lennox VAV box with a stuck actuator drifts 5–10°F before anyone complains. We rebuild or replace the actuator and recalibrate the zone, often avoiding a full DDC conversion the building isn’t budgeted for yet.
- Cooling tower sump float switches sticking from marine-layer algae. Century City’s persistent marine influence breeds biological growth in rooftop cooling towers. When the float switch sticks, condenser water flow drops and your Lennox chiller or condensing unit trips on high head pressure. We clean the sump, replace the switch, and treat the water loop — usually same day.
- VAV box reheat coils clogging with central plant sediment. Aging chilled water piping in Century City’s high-rises sheds rust and scale. That sediment collects in Lennox fan coil and VAV reheat coils, killing capacity and driving energy bills up 30% before anyone traces it. We pull and flush coils, or replace when they’re too far gone.
- Lennox Merit ML14XC1 short-cycling on high-rise rooftops. Restricted airflow from tower debris or failed economizer actuators causes these workhorse condensers to cycle rapidly, burning contactors and compressors. We diagnose whether it’s the unit or the building system causing the stress.
- SLP98V furnace soot production in residential condos. Even with mild Century City winters, improper gas pressure or restricted combustion air in a tightly sealed high-rise mechanical room causes this 98% AFUE furnace to run rich. We clean the burner assembly, check manifold pressure, and verify venting — not just clear the error code.
Lennox Service in Century City: What Local Conditions Mean for Your Equipment
Century City is almost entirely a district of 1960s–1980s high-rise office and luxury residential towers built on the former 20th Century Fox back lot. That means virtually all HVAC work here is commercial high-rise infrastructure — chilled water plants, cooling towers, VAV systems — not the residential split systems you’d find three miles east in Lennox in Beverly Hills. Because the entire building stock was developed in a narrow window, a cohort of same-vintage towers is aging simultaneously, requiring central plant retrofits and pneumatic-to-DDC control upgrades in concentrated waves.
For Lennox owners, this creates a specific challenge: many Century City towers still rely on original 1960s–70s control systems. When we install a new Lennox condensing unit, we often have to retrofit existing BACnet controllers to the building’s BAS — a step unique to this dense high-rise market. At 1900 Avenue of the Stars, our crew handled a Lennox repair in Santa Monica-style high-rise challenge, replacing a failing Merit ML14XC1 condenser on a 41st-floor residential suite. The original pneumatic controls governing the VAV box had drifted 8°F. We rebuilt the zone damper actuator and integrated the new Signature XC20 into the building’s BAS, restoring comfort and saving the HOA a full DDC conversion.
The marine layer that keeps Century City cooler than the Valley also keeps humidity elevated inside aging air-handling units. Coil cleaning and drain pan maintenance aren’t annual luxuries here — they’re higher-frequency necessities to prevent biological growth that restricts airflow and triggers Legionella concerns in commercial buildings.
Lennox Models & Products We Service in Century City
We work on the full Lennox residential and light commercial lineup, with deep experience on the models most common in Century City’s high-rise condos and office towers:
- Signature XC20 — variable-capacity condenser, often selected for premium residential suites where noise and precise humidity control matter. We stock OEM inverter boards and scroll compressors for fast turnaround.
- Merit ML14XC1 — the workhorse single-stage condenser we see on rooftops and intermediate floors throughout Century Park East and Century Park West. Capacitors, contactors, and fan motors on the truck; OEM coils when needed.
- SLP98V — modulating gas furnace, typically in penthouse mechanical rooms or dedicated heating closets. Heat exchangers are OEM-only; we’ll advise honestly if the unit’s age justifies replacement versus repair.
- G60 — older single-stage furnace still running in some 1980s-era residential conversions. Parts availability is narrowing; we source through our Lennox dealer network or recommend upgrade paths when repair economics stop making sense.
Our parts stance is simple: OEM for anything that touches refrigerant, combustion, or structural integrity. Quality aftermarket for electrical components where the failure mode is predictable and the cost difference is real. We don’t markup parts to force a replacement sale.
Lennox Service Pricing in Century City

What drives cost in Century City specifically: high-rise access (freight elevator coordination, after-hours scheduling), the complexity of building-wide systems versus standalone units, and whether we’re integrating with existing BAS or pneumatic controls. A simple capacitor swap on a Merit ML14XC1 runs toward the low end. A Signature XC20 install with BAS integration and pneumatic actuator rebuild runs toward the high end.
Every estimate is free and itemized. We don’t quote over the phone for high-rise work — we need eyes on the mechanical room, the rooftop access, and the existing controls. Call (844) 875-9451 to schedule.

FAQs — Lennox HVAC in Century City
My Century City office tower has a Lennox rooftop unit that short-cycles — do you service commercial equipment?
Yes. We service Lennox commercial rooftop units, chillers, and split systems in Century City high-rises. Short-cycling usually points to cooling tower flow issues, failed economizer actuators, or oversized staging in buildings that have been reconfigured since original install. We diagnose the root cause, not just the symptom. Call (844) 875-9451 for a free assessment.
Can you convert my 1960s Lennox pneumatic zone control to a modern DDC system?
Yes, and this is concentrated work in Century City where original pneumatic systems are increasingly unsupportable. We design and install DDC conversions using BACnet-compatible controllers, integrating new Lennox equipment with your building’s existing BAS. We also rebuild individual pneumatic actuators when a full conversion isn’t budgeted yet.
Do you pull permits for Lennox work in Century City high-rises?
Permit requirements vary by building and scope. We handle all City of Los Angeles permit filings for equipment replacement and control modifications, and we coordinate with your building engineer and HOA for mechanical room access and fire alarm integration. Commercial high-rise work doesn’t move without proper documentation.
My Lennox SLP98V furnace is producing soot — common issue here?
It’s not common when the furnace is properly maintained, but we see it in Century City’s sealed high-rise mechanical rooms where combustion air is restricted. Soot indicates incomplete combustion, usually from low gas pressure, dirty burners, or inadequate venting. It’s a safety issue — shut the unit down and call us. Call (844) 875-9451; we’ll prioritize this.
How often should I replace the air filter on my Lennox Signature system in a Century City condo?
Every 60–90 days for standard 1-inch pleated filters in most Century City residential units. If your building is near ongoing construction — and several towers along Avenue of the Stars have been in mixed-use redevelopment — check monthly. Restricted airflow in a variable-capacity Signature XC20 forces the inverter to overwork, shortening compressor life. We stock common Lennox filter sizes and can set up a maintenance schedule. Call (844) 875-9451 to arrange.
