We’re Meridian Heating & Air Los Angeles, and we’ve been keeping Lennox homes warm through 19 winters of hands-on HVAC work.

Call (877) 454-5066 for a free estimate — we’ll walk you through what’s actually wrong and what it’ll take to fix it.
Why Meridian Heating & Air Los Angeles Is Lennox’s Preferred Heating & Furnace Company
We’ve built our reputation in Lennox one service call at a time. Our 286 verified reviews average 4.8 out of 5 stars, and a solid share of those come from homeowners right here in the 90304 zip code who’ve had us back two, three, four times because the same person shows up.
That person is Anthony Moreno. He’s the founder, and he’s the one who climbs into your crawl space, reads the model plate on your wall furnace, and knows whether the part you need is still manufactured or if it’s time to talk retrofit. In Lennox, that matters more than in most places. The housing stock here is old, the permits run through LA County, not a city office, and the coastal conditions chew through equipment differently than they do inland. You want someone who’s navigated all three before.
Our response time to Lennox is typically same-day for standard calls and prioritized for no-heat emergencies. We know the streets — Freeman Avenue, Lennox Boulevard, the apartment courts off Inglewood Avenue — and we don’t waste time getting lost or guessing which County portal handles your inspection.
Our Heating & Furnace Services in Lennox
Furnace Repair
Furnace repair in Lennox runs $150–$700 depending on what’s failed. The most common winter call we get here isn’t a major component failure — it’s a nuisance lockout caused by jet exhaust particulate from LAX’s south runways clogging the burner orifice or coating the flame sensor. The particulate load in Lennox is genuinely heavier than in Hawthorne or Inglewood, just a mile away, because of the flight path geometry. We clean the assembly, test the flame signal, and get heat restored. If your pilot keeps going out or your furnace cycles on safety, that’s usually the culprit in this neighborhood.

Furnace Replacement
When a furnace replacement makes more sense than another repair, Lennox homeowners typically invest $3,500–$7,500 for a complete system. We factor in the tight crawl spaces and uninsulated attics common to Lennox’s 1940s–1960s housing stock — running new ductwork through a 24-inch crawl under a stucco bungalow is standard work for us, not a surprise add-on. We install Trane, Lennox, Goodman, and Rheem systems, and we’ll recommend the right unit for your space rather than whatever’s on the truck. Every replacement we handle in unincorporated Lennox goes through LA County Building and Safety, and we file the permit correctly the first time because we know the County portal — not the city hall systems that contractors from incorporated cities often try to use.

Furnace Tune-Up
A furnace tune-up in Lennox costs $95–$235 and should happen before the first cold snap. Given the coastal humidity and aviation particulate here, we shorten the standard inspection interval for Lennox customers. Your evaporator coil and drain pan need checking for biological growth that thrives in this moisture, and your burner assembly needs cleaning more often than the manufacturer’s generic schedule suggests. We check gas pressure, test safety switches, and inspect the heat exchanger for cracks. It’s preventive work that keeps you from making an emergency call in January.

Heat Exchanger Inspection & Replacement
Heat exchanger inspection runs $80–$200, and replacement is often bundled into a larger repair or replacement decision. In Lennox, we see heat exchangers fail faster than inland because coastal humidity in uninsulated crawl spaces accelerates rust and corrosion. We serviced a 1950s stucco bungalow on Freeman Avenue where the original floor furnace had a cracked heat exchanger from decades of jet exhaust corrosion. Rather than source a discontinued part, we retrofitted a modern 80% AFUE Goodman gas furnace and ran new ductwork through the tight crawl space — passing the LA County inspection on the first try because we know the portal. If we find a crack during inspection, we’ll show you the camera footage and explain whether repair or full replacement is the smarter money.

Trusted Brands We Service in Lennox
We work on your brand — whatever’s keeping your Lennox home warm. Our hands-on experience covers Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For Lennox customers, that means we don’t show up, shrug at an older unit, and try to sell you something new. We stock common parts locally and can source same-day for most failures. If you’ve got a Lennox-brand furnace (the manufacturer, not the city — confusing, we know) or a Goodman wall unit from the 1990s, we’ve repaired both this month.
Common Heating & Furnace Problems We See in Lennox Homes
- Jet exhaust particulate clogs burner orifices and flame sensors. LAX’s south runways send combustion byproducts directly over Lennox. We see furnaces lock out on safety because the flame sensor can’t read through the coating. Shorter filter-change intervals and annual burner cleaning prevent this.
- Coastal humidity rusts heat exchangers in crawl-space wall furnaces. The marine layer keeps Lennox cooler than inland LA, but the persistent moisture in uninsulated spaces corrodes metal faster than in drier South Bay communities like Torrance. We inspect for rust blooms and pinhole leaks that can admit carbon monoxide.
- Original 1950s parts are obsolete. Pilot assemblies, gas valves, and thermocouples for early floor and wall furnaces haven’t been made in decades. We keep some rebuilt stock, but often the honest recommendation is a modern retrofit with proper venting and safety controls.
- Tight crawl spaces complicate every repair and replacement. Lennox’s dense, older housing stock means we’re working in 18–30 inch clearances, running duct around original plumbing and wiring. It’s slow, careful work that inexperienced crews rush and get wrong.

What moves you within these ranges? Parts availability for older Lennox equipment, the complexity of crawl-space access, and whether LA County permitting is required for the scope of work.

FAQs — Heating & Furnace in Lennox
Yes. Because Lennox is unincorporated LA County, all furnace replacements require a permit through LA County Building and Safety, not a city hall. We handle the filing, the inspection scheduling, and the correction of any notes — most of our Lennox replacements pass on the first inspection because we know the County portal and the specific documentation they want to see. Call (877) 454-5066 and we’ll walk you through the timeline.
The jet exhaust particulate from LAX’s south runways coats your pilot assembly and thermocouple, causing weak flames and intermittent shutdowns. This is a genuinely Lennox-specific problem — we don’t see it at this frequency in Hawthorne or Inglewood. Cleaning the pilot orifice and replacing the thermocouple usually solves it, but we also check for draft issues in older venting. Call (877) 454-5066 for a same-day look.
Sometimes, but often the parts are obsolete. We’ve sourced rebuilt gas valves and pilot assemblies for some 1950s units, but if the heat exchanger is cracked or the cabinet is rusted through, replacement is the only safe option. We don’t recommend band-aid repairs on combustion equipment — carbon monoxide risk is real. We’ll inspect yours honestly and tell you which side of the line you’re on. Estimates are free; call (877) 454-5066.
Lennox’s marine-layer moisture accelerates rust on heat exchangers, burners, and cabinet metal, especially in uninsulated crawl spaces and closets. It also promotes biological growth in drain pans and on evaporator coils that share air handling with your furnace. We address this with corrosion-resistant materials when we replace equipment, and we recommend more frequent tune-ups than the generic manufacturer schedule. For a humidity-specific inspection, call (877) 454-5066.
We install Trane, Lennox, Goodman, and Rheem most often in Lennox, chosen for reliability in coastal conditions and parts availability in the LA market.
