LC Heating & Air provides professional, honest AC installation for Los Feliz homes. We focus on proper sizing through Manual J calculations and quality workmanship to ensure your system lasts.
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. These properties often feature original plaster walls, tile roofs, and unique layouts that make HVAC installation and ductwork routing genuinely challenging. We understand the specific 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 homes with different insulation and window characteristics than modern builds.
A new air conditioner is a major home comfort investment. LC Heating & Air sizes your system correctly using Manual J load calculations, selects equipment that matches your home's existing ductwork and insulation, and installs it to manufacturer specifications. An oversized or undersized unit costs you money every month. We get the sizing right so you aren't paying for equipment that doesn't perform.

Local HVAC Challenges in Los Feliz
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 homes here 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.
How We Size Your New AC System
Proper equipment sizing is the single most important factor in a successful AC installation. An oversized system cools the house quickly but shuts off before completing a full dehumidification cycle, leaving your home feeling cold but clammy. An undersized system runs continuously on hot days, never reaching the setpoint, consuming excessive electricity. Both problems result from skipping the Manual J load calculation.
LC Heating & Air performs a complete Manual J calculation on every installation. We measure your square footage, ceiling height, insulation R-values, window area and orientation, number of occupants, and local design temperatures. We then add a safety margin appropriate for your specific microclimate. The result is a system that maintains your desired temperature even on the hottest day of the year without the energy waste of oversizing.
California Rebates & Incentives
California offers generous HVAC rebates that can significantly reduce the cost of a new AC system. The TECH Clean California program offers rebates up to $3,000 for qualifying heat pump installations. SCE offers additional rebates of $500–$1,200 for high-efficiency cooling equipment. SoCalGas provides rebates for qualifying furnace replacements that are often paired with AC installations.
To qualify, the new system must meet minimum efficiency requirements—typically SEER2 16+ for central AC and SEER2 18+ for larger rebate tiers. The system must be installed by a licensed contractor, and proper permits must be pulled. LC Heating & Air handles all rebate paperwork and documentation, identifying every applicable incentive during your estimate appointment.
What to Expect on Installation Day
A standard residential AC installation takes one full day—typically 6–8 hours for a straight replacement and 8–10 hours for a new installation with electrical work or ductwork modifications. Our two-technician crew arrives in the morning with all equipment pre-staged. We lay protective floor runners, set up the work area, and confirm the installation plan with you before starting.
The process includes removing the old equipment, setting the new outdoor unit, installing the new evaporator coil, connecting the refrigerant line set, pulling a deep vacuum, and performing a complete commissioning test. We measure superheat and subcooling to verify the charge, check airflow, and verify the thermostat is calibrated. You get a complete commissioning report and registered warranty paperwork before we leave.
Repair vs. Replace: An Honest Look
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 a system that is 12+ years old and needs frequent repairs, or if a repair estimate exceeds 50% of the replacement cost. We also consider if the system can no longer maintain temperature on days above 90°F.
If you are moving into a home with no existing AC system, or if you are looking to upgrade to a more efficient, rebate-eligible system, replacement is often the most practical path forward. We provide written estimates so you can make an informed decision without feeling pressured.

What Los Feliz customers say about ac installation
Verified reviews from homeowners in Los Feliz and nearby neighborhoods who used our ac 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.”
