A new furnace is a 20-year investment. LC Heating & Air selects the right equipment for your home's heating load, ductwork, and budget — then installs it to code with all permits pulled. We won't push you toward oversized or unnecessary equipment. Most installations are completed in a single day with minimal disruption.
I'm Leo, owner of LC Heating & Air. When you're looking at a furnace installation in Sherman Oaks, you're usually dealing with one of two things: an older system that finally gave up, or a home renovation where the existing unit just isn't cutting it anymore. My job isn't to sell you the most expensive box on the shelf; it's to make sure your home stays comfortable without wasting your money on gas or unnecessary equipment.
Sherman Oaks has a mix of mid-century ranch homes and custom properties that present unique challenges, from tight attic access to aging ductwork. We focus on the details that matter—proper airflow, gas line safety, and correct sizing—so you don't end up with a system that short-cycles or fails prematurely. We're licensed (CSLB #1073586) and we handle everything from the permit process to the final safety check.

Local HVAC Challenges in Sherman Oaks
Sherman Oaks' 1950s and 1960s housing stock is in a critical transition period — much of the original HVAC equipment installed in these homes is at or near end of life. Many homes have attic-installed air handlers with original duct systems showing deterioration: disconnected flex duct, collapsed trunk line insulation, and register boot seal failures. We assess duct condition honestly during every project and recommend duct remediation when it would meaningfully affect new equipment performance.
Because of the Valley's climate, we see a lot of systems that were originally sized incorrectly. An oversized furnace will heat a room too fast and then shut off, which leaves the rest of the house cold and puts unnecessary wear on the blower motor. We use Manual J calculations to ensure the unit we install is the right size for your specific square footage and insulation levels.
Neighborhood Context and Modern Upgrades
Sherman Oaks sees strong demand for heat pump upgrades as homeowners replace aging gas furnaces. The Valley's mild winters make heat pumps practical as a complete heating and cooling solution, and the combination of federal tax credits and TECH Clean California rebates has made the economics significantly more favorable than even three years ago.
We have completed dozens of heat pump conversions in Sherman Oaks and can walk you through the current rebate landscape during a free in-home assessment. If you prefer to stick with a traditional gas furnace, we install 80% and 96% AFUE units that are reliable and efficient. We'll look at your SoCalGas usage history to help you decide if the higher upfront cost of a 96% unit is actually going to pay for itself in your home.
Our Diagnostic and Installation Process
Before we touch a single tool, we assess your current setup. We look at your gas supply, flue venting, and electrical panel capacity. If your panel can't handle a new system, we'll tell you upfront so there are no surprises on the invoice. We don't believe in 'hidden' costs.
Once we start the installation, we handle the removal of your old unit and ensure the new one is commissioned correctly. This includes testing for carbon monoxide, verifying combustion levels, and making sure the airflow is balanced. We pull all required city permits and handle the final inspection, so you don't have to deal with the bureaucracy.
Repair vs. Replace: An Honest Conversation
I tell my customers the same thing every time: if a repair is safe and makes financial sense, fix it. But if your furnace is 18+ years old and you're looking at a repair bill that's half the cost of a new unit, it's time to have a serious talk about replacement.
Frequent repairs are a sign that the system is nearing the end of its life. We won't pressure you into a new unit if a simple part replacement will get you through another few seasons. We're here to build a relationship, not just make a quick sale.
Understanding Costs and Rebates
Furnace costs vary based on efficiency and technology. A standard 80% AFUE furnace is a solid, budget-friendly choice, while a 96% AFUE or variable-speed unit offers better comfort and lower long-term gas bills. We provide written estimates for 2–3 different options so you can choose what fits your budget.
Don't forget about incentives. SoCalGas offers rebates for qualifying high-efficiency gas furnaces, and we handle all the paperwork for you. We also offer financing through GreenSky, including 12-month same-as-cash options, to help manage the upfront cost.
Access and Scheduling in Sherman Oaks
Working in Sherman Oaks often means navigating narrow roads and hillside access. We plan our logistics carefully to ensure we have the right equipment and enough time to get the job done right. Most of our furnace installations are completed in a single day, usually between 4 and 7 hours.
We offer same-day service options for emergencies and are available to answer your questions whenever you need us. You can reach us at (323) 970-3113 to schedule an assessment.
Common Mistakes We See
The biggest mistake I see is sizing a furnace based on square footage alone. A home with high ceilings and lots of glass needs a different heating load than a home with standard insulation. Another common error is failing to address duct leakage. If you put a brand-new, high-efficiency furnace on a leaky duct system, you're just paying to heat your attic.
We also see installations where the combustion venting is done incorrectly. This is a major safety issue. We follow NFPA 54 standards for all venting to ensure your home is safe and your furnace operates as intended.
Your Health and Safety
Your furnace is a gas appliance, and safety is our top priority. Every installation includes a pressure test on gas lines and a thorough check of the flue venting. We want to make sure no carbon monoxide is leaking into your living space.
We also ensure that the system is properly commissioned. This means we fire it up, check the temperature rise, and verify that the burners are igniting cleanly. You'll have peace of mind knowing your system is running exactly how the manufacturer intended.
Is It Time for a New Furnace?
If your gas bill has been creeping up year after year, or if your home just can't seem to reach a comfortable temperature on those chilly Valley nights, it might be time to look at your options. We'll come out, inspect your current system, and give you an honest assessment of whether a repair will hold or if it's time to upgrade.
We'll provide a written estimate, explain the pros and cons of different efficiency levels, and help you decide what makes the most sense for your home's long-term comfort.
