How We Size Your New AC System in Los Angeles
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 and causing the compressor to short-cycle, which dramatically shortens equipment life. An undersized system runs continuously on hot days, never reaching the setpoint, consuming excessive electricity without maintaining comfort. Both problems result from the same mistake: skipping the Manual J load calculation.
LC Heating & Air performs a complete Manual J calculation on every installation. We measure your home's square footage, ceiling height, insulation R-values, window area and orientation, number of occupants, and the local design temperature for your specific neighborhood. 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 some of the most generous HVAC rebates in the country. 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 for most rebates, the new system must meet minimum efficiency requirements, be installed by a licensed contractor, and pass all required inspections. LC Heating & Air handles all rebate paperwork and documentation for you, ensuring you get the incentives you qualify for.
What to Expect on Installation Day
A standard residential AC installation takes one full day. 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 unit, brazing connections, pulling a deep vacuum to remove moisture, and performing a complete commissioning test. We verify refrigerant charge, airflow, and temperature differentials before walking you through the system operation and maintenance schedule.
Working with Los Angeles Housing
Los Angeles is home to a mix of single-family homes, duplexes, and older multifamily buildings. We understand the specific challenges of these structures, including attic ductwork, older electrical layouts, and limited equipment access.
Before we recommend a repair or replacement, we check your electrical panel, duct condition, and equipment placement. This ensures that the new system we install will perform as expected and won't be limited by existing infrastructure issues.
Repair or Replace?
If your AC is 12+ years old and needs frequent, expensive repairs, it is often more cost-effective to replace it. If the repair estimate exceeds 50% of the cost of a new system, we will recommend replacement.
We are honest about your options. If a simple repair will get you through another few seasons, we will tell you. If the pattern of failure points to a system that is at the end of its life, we will explain why and provide a clear, written estimate for replacement.
Safety and Compliance
We pull all required permits for AC installation in the City and County of Los Angeles. This protects you legally and ensures the installation passes inspection. Unpermitted work can void your homeowner insurance and create problems when you sell your home.
Proper installation also includes registering your equipment for the full manufacturer warranty. We ensure all paperwork is handled correctly so you are protected from day one.
Common Installation Mistakes
The biggest mistake we see is sizing by 'rule of thumb' rather than actual load calculations. Another common issue is failing to address ductwork problems, which can choke a new, high-efficiency system and prevent it from delivering the comfort you paid for.
At LC Heating & Air, we don't cut corners. We verify airflow and refrigerant levels during commissioning to ensure your system runs at peak efficiency from the start.
Making the Right Choice
Choosing an HVAC contractor is about finding someone who will be honest with you. We don't use high-pressure sales tactics. We look at your home, calculate the load, and give you options that make sense for your budget and your comfort.
Whether you need a simple repair or a full system replacement, we provide the information you need to make an informed decision. We are here to help you keep your home comfortable, year after year.

Verified reviews from homeowners in Los Angeles and nearby neighborhoods who used our ac installation service.
“AC compressor failed on the hottest day of the year. LC came out quickly, gave an honest assessment — said the compressor was still under manufacturer warranty — and helped me get it covered. Saved me over $1,200.”
“Replaced our 20-year-old Lennox system with a new high-efficiency Carrier. LC handled the permits, coordinated the Edison inspection, and finished a full replacement in one day. Impeccable workmanship.”
“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.”
