Larchmont Village and the surrounding neighborhoods—from the Rossmore Avenue corridor to the Plymouth Boulevard area—are defined by beautiful, historic homes. Whether you live in a classic Craftsman, a Spanish Colonial, or a Tudor, your heating system is likely a retrofit. These systems require a different approach than those in new construction. At LC Heating & Air, we understand that your home’s character is just as important as its comfort.
I’m Leo, and I’ve been working on HVAC systems across Los Angeles for years. My approach is simple: I don’t sell equipment; I solve problems. If your furnace is struggling, I’ll tell you if it’s worth a repair or if it’s time to look at a replacement. We focus on the details that matter—airflow, duct integrity, and combustion safety—to make sure your home stays comfortable without unnecessary costs.

The Larchmont HVAC Challenge
Larchmont’s older homes often present unique challenges. Many were built long before central heating was standard, meaning HVAC systems were added later, often in tight attic spaces or cramped closets. We frequently see undersized ductwork that restricts airflow, causing furnaces to overheat and short-cycle. If your system is constantly clicking on and off, it’s not just an annoyance; it’s a sign that the equipment is working harder than it should, which shortens its lifespan.
We also keep an eye on the electrical and venting conditions in these older structures. Before we recommend a new unit, we check your electrical panel capacity and the integrity of your existing flue. If we find asbestos-wrapped ducts—common in homes of this era—we’ll let you know immediately so you can plan for professional remediation. We don't cut corners; we make sure the job is done safely and to code.
Why Sizing Matters for Your Home
Many contractors use a 'rule of thumb' based on square footage to size a furnace. In Larchmont, that is a mistake. Because our winters are mild, an oversized furnace will heat your home too quickly and then shut down, only to restart minutes later. This 'short-cycling' wears out parts prematurely and leaves you with uneven temperatures.
At LC Heating & Air, we perform a Manual J heat loss calculation for every replacement. We look at your home’s insulation, window types, and orientation to determine exactly how much heating capacity you actually need. This ensures your new system runs efficiently and lasts as long as it should.
Our Diagnostic Process
When I come to your home, I don't just look at the furnace. I look at the whole system. We check the ignition, burners, and flame sensors to see if the issue is a simple component failure. We also inspect the heat exchanger for cracks—a critical safety check because a cracked exchanger can leak carbon monoxide into your living space.
Once we have the full picture, we sit down with you. We explain what we found, why it’s happening, and what your options are. You won't get a high-pressure sales pitch; you’ll get a clear, written estimate so you can make an informed decision about whether to repair or replace.
Repair or Replace?
The decision to replace a furnace is a big one. My rule of thumb is simple: if the repair cost is more than half the price of a new system and your furnace is over 15 years old, replacement is usually the smarter financial move. You stop paying for repeated service calls and start saving on energy bills.
If a repair is the right choice, we’ll do it honestly and efficiently. If the system is at the end of its life, we’ll show you the numbers so you can see the long-term value of a new, high-efficiency unit.
Understanding Costs and Rebates
We know that furnace replacement is an investment. That’s why we help you navigate the available incentives. California’s TECH Clean California program and SoCalGas offer rebates for high-efficiency equipment that can significantly lower your upfront costs.
We provide a transparent breakdown of costs, including the equipment, labor, and permit fees. We don't hide anything in the fine print. We want you to know exactly what you are paying for and why it’s necessary for your home’s safety and performance.
Scheduling and Access
We know your time is valuable. When you call LC Heating & Air at (323) 970-3113, we work with you to find a time that fits your schedule. Because we are based nearby on Fairfax Avenue, we are well-positioned to serve Larchmont quickly.
During our visit, we assess the physical access to your equipment. Whether it’s in a tight attic or a crawlspace, we ensure we have the space to work safely and effectively. We respect your home and always leave our workspace clean.
Safety First
Your family's safety is our priority. Every furnace replacement we perform is pulled with a permit. This ensures that a city inspector verifies the work, confirming that the gas connections and venting meet current safety codes. We also perform a combustion safety check on every install to ensure no carbon monoxide is leaking into your home.
Never ignore a cracked heat exchanger or a CO detector alarm. If you suspect a safety issue, call us immediately. We take these calls seriously and will prioritize your safety above all else.

What Larchmont customers say about furnace replacement
Verified reviews from homeowners in Larchmont and nearby neighborhoods who used our furnace replacement service.
“Full system replacement in our 1930s Hancock Park home — not easy given the older construction. LC handled all the challenges: narrow access, old ductwork, low attic. Finished on time and on budget.”
“AC compressor failed on the hottest day of the year. LC came out quickly, gave an honest assessment — said the compressor was still under manufacturer warranty — and helped me get it covered. Saved me over $1,200.”
“Replaced our 20-year-old Lennox system with a new high-efficiency Carrier. LC handled the permits, coordinated the Edison inspection, and finished a full replacement in one day. Impeccable workmanship.”
