Lennox HVAC in North Hills, CA | Meridian Heating & Air Los Angeles
Independent Lennox in Northridge and North Hills service runs $175–$765 for repairs and $95–$235 for tune-ups, with most calls completed same day. What sets our work apart here is the 1994 earthquake rebuild cohort — thousands of Lennox systems installed in 1994–1997 are aging out simultaneously in this specific pocket of the Valley, and we’ve been tracking their failure patterns for nearly two decades. We service all Lennox residential and commercial lines with OEM-compatible parts, and Anthony Moreno still leads the installs himself. Call (877) 454-5066 for a free estimate.
Why North Hills Residents Choose Us for Lennox Service
We’ve been pulling Lennox units out of North Hills attics since before the iPhone existed. Anthony Moreno, our founder and lead installer, learned the trade at Los Angeles Trade-Technical College and has spent 19 years figuring out why systems fail in this specific terrain — not from a desk, but from crawling through 150°F attics in July.
That matters because Lennox builds good equipment, but good equipment still breaks when it’s fighting 105–110°F days with flex duct that’s been cooking since the Clinton administration. We carry OEM-compatible parts for the Lennox lines we see most in 91343 and 91393, and we don’t send a rotating crew of subcontractors. Anthony shows up on the job. Our Lennox sales & service covers everything from legacy Merit-series furnaces to current Dave Lennox Signature Collection heat pumps.
286 customers and counting have left us reviews averaging 4.8 stars. Most mention the same thing: the guy who diagnosed the problem is the guy who fixed it.
Common Lennox HVAC Problems We Solve in North Hills
- Compressor failure on XC14 and XC16 condensers. North Hills runs 25–30°F hotter than coastal LA on the same August afternoon. That constant high-load cycling burns out Lennox single-stage compressors faster than the manufacturer specs for “typical” climates. We check amp draw and refrigerant charge against actual operating conditions, not textbook baselines.
- Cracked heat exchangers in 1994–1997 G26 and G60 furnaces. The post-earthquake rebuild wave dumped hundreds of these units into North Hills homes. They’re 28–30 years old now. We find stress cracks that CO detectors won’t catch yet, and we don’t sugarcoat the replacement call when we do.
- Collapsed flex duct in super-heated attics. Attic temperatures hit 150–160°F here. Lennox’s rated airflow assumes intact ductwork, but we’ve pulled down flex runs that have literally sagged onto ceiling joists, choking supply to back bedrooms. Static pressure testing tells the real story.
- Failed capacitors and contactors on ML180 and EL180 furnaces. The heat itself degrades electrical components faster. We stock the Lennox-spec run capacitors and see this failure spike every July when North Hills hits triple digits for a week straight.
- Refrigerant leaks in legacy HPXA heat pumps. Vibration from poor original installation — common in the rushed post-’94 rebuilds — plus decades of thermal expansion in those attics creates pinholes at braze joints. We pressure-test and find the actual leak point, not just top off the charge.
Lennox Service in North Hills: What Local Conditions Mean for Your Equipment
Here’s something you won’t read on a generic Lennox service page: North Hills, then called Sepulveda, sat meters from the 1994 Northridge earthquake epicenter. The structural devastation triggered one of the most concentrated rebuilding waves in Valley history, and HVAC contractors — us included — were installing Lennox systems flat-out from 1994 through 1997. That cohort is now entering end-of-life together, creating a replacement surge that’s geographically specific to this neighborhood.
In Panorama City or Granada Hills, equipment ages out on a normal distribution. In North Hills, you’ve got entire blocks where the furnaces were all lit for the first time in the same six-month window. We’ve been tracking this for years. When Anthony walks into a tract home near Parthenia Street and sees a G26 or early Merit series, he already knows the heat exchanger is 28 years old and the original flex duct is R-4 at best. That’s not guesswork. That’s pattern recognition from nearly two decades of working this specific ZIP code.
The 105–110°F summer load in Lennox repair in Van Nuys and across the Valley just accelerates everything. A Lennox system that’s technically “working” in North Hills is often running at the edge of its safety margins by August. We measure actual supply air temperature at the register, not just the thermostat reading, because pre-heated supply from a 160°F attic can mask a system that’s failing in plain sight.
Lennox Models & Products We Service in North Hills
We work on your brand — and with Lennox specifically, that means factory-trained familiarity with the full residential and light-commercial lineup. In North Hills, we regularly service Dave Lennox Signature Collection variable-capacity systems, Elite Series two-stage heat pumps and ACs, and Merit Series single-stage workhorses that have been grinding through Valley summers since the rebuild era.
We stock OEM-compatible capacitors, contactors, ignitors, and pressure switches for the models we see most in 91343 and 91393. For larger components — heat exchangers, compressors, control boards — we source Lennox-spec or exact-cross parts, not universal-fit substitutes that throw off system balance. Fast turnaround matters when your attic is 155°F and your family is sleeping in the living room. We don’t make you wait two weeks for a part that should be on the truck.
For indoor air quality concerns tied to your Lennox system — and in North Hills, dust infiltration from aging ductwork is a real issue — our Air Quality & Ventilation in North Hills page covers filtration, humidification, and duct sealing options.
Lennox Service Pricing in North Hills

What drives the cost? For repairs, it’s parts availability and accessibility — a control board swap on a ground-mounted condenser is straightforward; the same job in a cramped attic with 6-inch clearance takes longer and costs more. For installs, factors include whether we’re reusing existing ductwork (often not advisable in North Hills), electrical upgrades, and permitting through the City of Los Angeles.

FAQs — Lennox HVAC in North Hills
No. Meridian Heating & Air Los Angeles is an independent Lennox service provider, not a manufacturer-authorized or factory-dealer location. We’re experienced across nine major brands including Lennox, which means we service your equipment based on technical training and field experience rather than dealer-program obligations. If your system isn’t working right, something is wrong — and it’s usually fixable once you actually look at it.
We use OEM-compatible or Lennox-spec parts for repairs, and we avoid universal-fit components that can throw off system efficiency or void remaining warranty coverage. For common North Hills failures — capacitors, contactors, ignitors — we stock what we need to finish the job in one visit. Call (877) 454-5066 if you’re wondering about parts availability for your specific model.
Most residential repairs run 1–3 hours. Same-day completion is standard for stocked parts. If we need to order a heat exchanger or compressor, we’ll give you a realistic timeline — and we’ll be straight if temporary heating or cooling makes sense while you wait.
Everything from 1990s-era Merit and G-Series furnaces through current Dave Lennox Signature Collection variable-capacity systems. In North Hills specifically, we see heavy concentrations of 1994–1997 Elite and Merit installs from the rebuild era, plus newer XC and XP heat pumps in updated homes. We don’t turn away legacy equipment just because it’s old.
For a 28–30 year old system in North Hills, replacement is usually the smarter money. You’re past the design life, you’re paying summer peak rates to run inefficient equipment, and the next repair is rarely the last. That said, if your Lennox is under 12 years old and the repair is under $400, fixing it often makes sense. We’ll give you both numbers and let you decide. Call (877) 454-5066 for a free estimate — no pressure, just the math.
