At LC Heating & Air, we believe in honest, plain-spoken advice. If your heating and cooling systems are aging, we will tell you whether a repair is a sensible fix or if it is time to look at a full replacement based on your home's unique needs.
Larchmont Village and the surrounding neighborhoods are defined by beautiful, historic homes—Craftsman bungalows, Spanish Colonial Revival, and Tudor styles. These homes were often built long before central air conditioning was standard. When we work in Larchmont, we aren't just swapping out boxes; we are working within the constraints of older architecture, retrofitted ductwork, and specific electrical layouts.
I am Leo, the owner of LC Heating & Air. My team and I have been serving this area for years, and we know that a one-size-fits-all approach doesn't work here. Whether you are dealing with a failing furnace or an AC unit that can't keep up with the summer heat, we start by looking at the whole system—ducts, electrical, and airflow—to give you a clear, honest recommendation.

Common HVAC Challenges in Larchmont
In Larchmont, we frequently see systems that were added as afterthoughts to older homes. This often means the ductwork is undersized for modern equipment, or the electrical panel is maxed out. If you try to force a high-efficiency system onto old, leaky ducts, you won't get the comfort you paid for.
We also encounter older homes where asbestos-wrapped ducts may be present. We identify these issues during our initial assessment. We don't believe in surprises; we include any necessary duct repairs or electrical upgrades in our written estimate so you know exactly what the project entails before we start.
Why Neighborhood Character Matters
Larchmont homeowners invest in their properties, and we respect that. When we recommend a system, we look at the long-term value. Sometimes, a high-efficiency system is the right choice, but other times, a standard-efficiency unit makes more sense depending on your home's insulation and ductwork.
We always provide an honest analysis of whether a premium system will actually pay for itself through energy savings. Our goal is to ensure your HVAC system supports the comfort of your home without requiring unnecessary modifications that could affect its character.
Our Diagnostic Process
We don't just look at the equipment. We perform a full Manual J load calculation to ensure the new system is sized correctly for your specific square footage, window orientation, and insulation levels. This is the only way to guarantee the system will actually keep you comfortable.
We also inspect your electrical service and duct condition. If your current system is 12–15 years old, we will tell you if it is worth repairing or if the pattern of failures suggests that a full replacement is the more economical path.
Repair or Replace?
This is the most common question I get at the kitchen table. If your furnace is 15–20 years old and your AC is 12–15 years old, replacing both at once is often the smartest move. You pay one mobilization fee, and you get a matched system that is designed to work together efficiently.
If the repair cost is high and the system is nearing the end of its life, I will be the first to tell you that replacing it is the better investment. We aren't here to sell you equipment you don't need; we are here to make sure your home stays comfortable for the long haul.
Costs, Rebates, and Incentives
A full HVAC replacement in a typical LA home generally runs between $7,500 and $14,000. This includes the condenser, air handler, and furnace. We also offer heat pump alternatives, which are excellent for our mild climate.
We help you navigate the available incentives, such as the TECH Clean California program and federal tax credits. We handle the documentation so you can focus on the comfort of your home. We provide a clear, written estimate after our assessment so you know exactly what you are paying for.
Scheduling and Access
We know your time is valuable. Most full replacements in homes with existing ductwork are completed in a single day, typically 6 to 10 hours. If we need to perform significant duct repairs, it might take two days, but we will let you know that upfront.
We check access, electrical capacity, and equipment placement before we start. This preparation prevents mid-job delays and ensures that the installation goes smoothly.
Common Mistakes to Avoid
The biggest mistake is replacing an AC unit without checking the furnace or the ductwork. If you put a new, high-efficiency AC on an old, inefficient furnace or leaky ducts, you are essentially wasting your money. The system won't perform as expected, and you will likely face another repair bill for the furnace within a few years.
Another mistake is skipping the load calculation. If the system is oversized or undersized, it will cycle on and off too frequently, leading to uneven temperatures and premature equipment failure. We always perform a Manual J calculation to prevent this.
Health and Safety
Your safety is our priority. During our assessment, we look for potential hazards like carbon monoxide risks from old furnaces, proper venting, and electrical safety. We ensure that every installation meets current code requirements.
We are fully licensed (CSLB #1073586) and insured. When we finish a job, we don't just leave; we perform full commissioning, including airflow measurements at every register and verification of the refrigerant charge, to make sure the system is safe and running exactly as it should.
Making the Right Choice for Your Home
Choosing to replace your HVAC system is a big decision. At LC Heating & Air, we make it simple. We look at the age of your equipment, the cost of recent repairs, and your long-term goals for the property. If your system is 15 years old and struggling, we will give you a clear, honest estimate for a replacement that fits your home.
We provide options, including heat pumps and traditional systems, so you can choose what works best for your budget and comfort. We are here to help you make an informed decision, not to push a sale.
