I'm Leo, owner of LC Heating & Air. When you're dealing with a furnace that isn't working right, you don't need a sales pitch—you need a clear look at what's going on inside the unit. Serving Sherman Oaks, I see a lot of mid-century homes where the original or secondary HVAC systems are finally reaching the end of their service life.
My goal is to help you decide if a repair will keep you comfortable for a few more years or if it's time to invest in a new system. We handle everything from the initial Manual J load calculation to pulling the required permits, ensuring your home stays safe and efficient.

Common HVAC Issues in Sherman Oaks
Sherman Oaks has a mix of 1950s and 1960s ranch homes that often have attic-installed air handlers. A common issue I see is failing ductwork—collapsed insulation, disconnected flex ducts, and leaky register boots. If you replace the furnace but leave the leaky ducts, you're just paying to heat your attic.
Because of our local climate, many systems are oversized. When a furnace is too big for the house, it short-cycles, meaning it turns on and off too frequently. This wears out parts faster and makes your home less comfortable. We check your duct condition and perform a proper load calculation to make sure the new equipment actually fits your home.
Mid-Century Home Considerations
Many homes in the Sherman Oaks Hills and surrounding neighborhoods have unique access challenges. Whether it's tight attic spaces or equipment tucked into narrow closets, we plan our installations around the realities of your home's layout.
We also see many homeowners looking to transition to heat pumps. Given our mild winters, a heat pump can often handle both heating and cooling efficiently. We can help you navigate the TECH Clean California rebates and federal tax credits to see if this is the right move for your property.
Our Diagnostic Approach
When I come out to your home, I don't just look for a quick fix. I inspect the ignition, burners, flame sensor, and venting. Safety is the priority—especially checking the heat exchanger for cracks, which can leak carbon monoxide into your living space.
If a repair is possible and makes sense, I'll tell you. If the system is too far gone or the cost of the repair is closing in on the cost of a new unit, I'll explain why replacement is the smarter financial choice.
Repair vs. Replace: The Honest Truth
The general rule I follow: if a repair costs more than half the price of a new system and your furnace is 15+ years old, replacement is usually the better investment. You stop throwing money at a declining system and start benefiting from the efficiency gains a modern furnace delivers.
We provide written estimates so you can see exactly what you're paying for. If we can get you another few years of reliable heat with a simple repair, we will. We aren't here to sell you equipment you don't need.
Understanding Costs and Rebates
Furnace replacement costs in LA typically range from $3,200 to $5,800 depending on the equipment size and efficiency. We help you navigate the rebate landscape, including SoCalGas and TECH Clean California incentives, which can offset a significant portion of the cost.
We also provide a payback analysis. If you're looking at a high-efficiency 96% AFUE unit, we'll calculate how long it will take to pay for itself in gas savings so you can make an informed decision.
Scheduling and Access
We are based on Fairfax Avenue, which puts us about 30 minutes from Sherman Oaks. We understand that your time is valuable, so we offer same-day service options and clear communication about our arrival window.
Whether you're in the Sherman Oaks Hills or near the Sepulveda Basin, we are equipped to handle the specific access challenges of your property, from ladder safety to tight equipment clearances.
Mistakes to Avoid
The biggest mistake I see is skipping the permit. Furnace replacement involves gas lines and venting; it must be permitted and inspected to ensure your family's safety. Unpermitted work is a major liability and can cause headaches if you ever sell your home.
Another mistake is relying on 'rule of thumb' sizing. A furnace that is too big will short-cycle and waste fuel. We always perform a Manual J calculation to ensure your new system is sized exactly for your home's heat loss.
Health and Safety First
Your furnace is a combustion appliance. If the heat exchanger is cracked, it can leak carbon monoxide. We test for CO output and verify that your venting system is up to current code. We don't cut corners on safety—ever.
When we install a new system, we verify combustion air and test the temperature rise to ensure the unit is running exactly as the manufacturer intended.
Is It Time for a New Furnace?
If your furnace is over 15 years old, making strange banging or booming noises, or if your gas bills are creeping up, it's time for a professional look. If we find a cracked heat exchanger, that's a clear sign that replacement is necessary for your safety.
If the system is still running well but just needs a tune-up, we'll tell you that too. Our goal is to be the contractor you trust for the long haul, not just for one job.
How the visit works
We inspect your current system, flue condition, and ductwork, then perform a Manual J heat loss calculation.
We present 2–3 options at different efficiency levels with rebate information and honest payback analysis.
A licensed technician removes the old unit, handles gas line connections, updates venting, and installs the new furnace.
We test combustion, measure temperature rise, verify CO output, and walk you through the new system.
Cost factors we review before quoting
- • Equipment efficiency (AFUE rating)
- • Ductwork modifications or repairs
- • Venting and gas line updates to meet current code
