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.
Los Feliz is one of the most architecturally distinct neighborhoods in Los Angeles — home to a dense concentration of 1920s and 1930s Spanish Colonial Revival and Mediterranean-style homes, many with original plaster walls, tile roofs, and architectural features that make HVAC installation and ductwork routing genuinely challenging.
LC Heating & Air has worked in Los Feliz homes for two decades and understands the unique requirements of older construction: how to run new ductwork without destroying original plasterwork, where to locate condensing units on tight hillside lots, and how to size systems correctly for older homes with different insulation and window characteristics than modern construction.

Local HVAC Challenges
Los Feliz's older housing stock presents three consistent HVAC challenges: original ductwork that is undersized for modern comfort expectations, plaster-and-lath construction that complicates new duct runs, and hillside lots with limited space for outdoor condenser placement. We use flexible installation approaches including mini-split systems for rooms that cannot be served efficiently by a central duct system, and we always photograph and document duct routing before closing walls so homeowners have records of what is in their walls.
Many Los Feliz homes have partially original duct systems — galvanized steel trunk lines from original installations combined with flex duct extensions added in various decades. This patchwork ductwork is a common source of efficiency problems, hot and cold spots, and duct leakage. We assess the full duct system during every installation project and recommend consolidation or replacement when the existing ductwork would significantly compromise new equipment performance.
Our Assessment Process
We inspect your ductwork, existing gas supply, flue venting, and electrical to identify any needed upgrades. We present 2–3 options at different efficiency levels with projected monthly savings and available rebates. Licensed installers complete the work in one day. Gas lines, venting, electrical — all done to code. We fire the furnace, verify combustion and CO levels, pass city inspection, and register your warranty.
Repair or Replace?
Furnace replacement in Los Angeles is a more nuanced decision than in colder climates, because the economics look different when a furnace runs only 30 to 60 days per year. A high-efficiency 96% AFUE furnace costs more upfront but saves on gas bills — however, the payback period in LA is longer than in Chicago or Denver because you simply use less gas. We run the actual numbers for each homeowner based on their SoCalGas usage history, not generic claims about energy savings.
If the system is worth repairing, we will tell you. If the pattern points to replacement, we will explain why. We look for signs like the furnace being 18+ years old, frequent repair needs, or a recent repair estimate exceeding 50% of replacement cost.
Investment and Rebates
We offer transparent pricing for various furnace tiers. Standard 80% AFUE furnaces range from $2,800–$4,500, while high-efficiency 96% AFUE units range from $4,000–$6,500. Premium variable-speed systems range from $5,500–$8,000. We also handle ductwork modifications ($500–$3,000) and electrical panel upgrades ($1,200–$2,500) if required.
SoCalGas offers up to $800 on qualifying high-efficiency gas furnaces, and TECH Clean California offers additional incentives. We handle the rebate paperwork for you.
Safety and Code Compliance
Every furnace installation requires a City of LA permit and a final inspection. We handle all of this. We ensure all gas connections are pressure-tested and combustion venting is installed to NFPA 54 standards. Proper sizing using Manual J methodology is critical to prevent short-cycling and ensure your home's air quality and safety are maintained.
Avoiding Common Pitfalls
Don't let any contractor size your furnace by square footage alone. Oversized furnaces short-cycle, waste gas, and wear out faster. We calculate your heating load using Manual J methodology — accounting for insulation levels, ceiling height, window area, and climate data. We also ensure your return airflow is sufficient, which is a common oversight in older Los Feliz homes.
Frequently Asked Questions
How long does a furnace installation take? Most residential installations are completed in one day — typically 4–7 hours. If ductwork modifications are needed, add a half to a full day.
What brands do you install? We install Carrier, Lennox, Trane, Rheem, Goodman, and American Standard. We'll match the right brand to your budget and ductwork.
Do you offer financing? Yes. We offer financing through GreenSky with options including 12-month same-as-cash and 60-month fixed payment plans.
Is a two-stage or variable-speed furnace worth it? In LA's mild climate, the payback period is longer than in cold-climate states. We'll give you an honest ROI comparison.
The LC Heating & Air Approach
We believe in explaining the 'why' behind every recommendation. Whether it's a simple repair or a full system replacement, we want you to understand the condition of your equipment before any work begins.
Our focus is on long-term reliability and comfort. We don't use high-pressure sales tactics; we provide the facts, the options, and the honest trade-offs so you can make the decision that fits your home and your budget.

What Los Feliz customers say about furnace installation
Verified reviews from homeowners in Los Feliz and nearby neighborhoods who used our furnace installation service.
“Pilot light kept going out on our older furnace. LC came out, replaced the thermocouple, cleaned the burner assembly, and did a full safety check. Fast, affordable, and they showed me how to relight it safely in the future.”
“Got a 3-zone Daikin system for our craftsman home — bedrooms upstairs, living room downstairs. Each room has its own temperature control and the monthly electric bill is actually lower than our old window units combined.”
“LC installed a Daikin heat pump in our Atwater craftsman. They coordinated with the electrician for the panel upgrade, pulled permits, and handled the TECH Clean rebate. Total came in under $8,000 after incentives.”
