I'm Leo, owner of LC Heating & Air. I provide honest, plain-spoken central AC repair and installation for Los Angeles homeowners. We focus on getting your system running right, whether that means a simple repair or a properly sized replacement.
Central air conditioning is the standard comfort solution for most LA single-family homes and larger condos. A central AC system uses a network of ducts to distribute cooled air throughout every room from a single outdoor condenser and indoor air handler. It is quieter and more comfortable than window units, and far more efficient when properly sized and installed.
At LC Heating & Air, we handle the full lifecycle of your cooling system. Whether you are dealing with a system that won't start on a hot day or you are looking for a long-term replacement plan, I provide the same level of care. We are CSLB licensed (#1073586) and serve the entire Los Angeles area with a focus on practical, honest solutions.

Central AC Repair, Maintenance, and Installation
Common Central AC Problems in Los Angeles
Central AC systems in Los Angeles fail in predictable ways. The most common service calls I handle are capacitor failures. The capacitor is what kicks the compressor and fan motor into starting, and it wears out every 5–10 years. Other frequent issues include refrigerant leaks, dirty evaporator coils causing reduced airflow and eventual freeze-up, clogged condensate drains, and thermostat malfunctions.
Most of these are same-day repairs. I stock parts on every truck for the most common central AC failures across all major brands like Carrier, Lennox, Trane, Rheem, Goodman, and Daikin. If your system is worth repairing, I will tell you. If the pattern points to replacement, I will explain why.
Why Your Home's Layout Matters
Los Angeles has a mix of single-family homes, duplexes, and older multifamily buildings. This variety means every HVAC job is different. We often see older electrical layouts or ductwork that was never designed for modern high-efficiency equipment. Before we recommend a repair or a new system, we check access, electrical capacity, duct condition, and equipment placement.
The two biggest factors in central AC performance are correct sizing and ductwork condition. An oversized system short-cycles and leaves humidity high. A system attached to leaky or undersized ductwork can't deliver conditioned air where it needs to go, leaving you with hot rooms no matter how low you set the thermostat.
How We Diagnose Your System
When I arrive at your home, I don't just look at the thermostat. I perform a full system inspection. This includes checking the refrigerant levels, the condition of the evaporator coil, the electrical components like the contactor and capacitor, and the airflow at the registers.
For new installations, we start with a Manual J load calculation. This ensures the equipment we install is the right size for your home's specific heat gain. We don't guess; we measure so you get a system that actually cools your home efficiently.
Repair or Replace: Making the Right Call
I believe in being honest about whether a repair is the right move. If your system is 12–18 years old and requires a major repair like a compressor replacement, it might be time to consider a new unit. However, if it's a simple electrical issue or a minor leak, a repair is usually the best path forward.
My goal is to provide a written estimate that makes sense before we touch the equipment. I will show you the math on energy savings for new SEER2-rated systems so you can decide if the investment is worth it for your specific situation.
Understanding Your Costs
We believe in transparency. A central AC diagnostic typically runs $125–$175. Repairs generally fall between $175 and $800 depending on the parts needed. If you need a full system replacement, costs range from $5,000 to $12,000 based on the size and efficiency level of the unit.
New equipment sold in California must meet a minimum SEER2 of 15.2. While higher-efficiency equipment costs more upfront, the energy savings at LA electricity rates can be significant. I will walk you through these numbers so you know exactly what you are paying for.
Scheduling Service in LA
We know that when your AC goes out in the middle of a heatwave, you need help fast. We offer same-day service options throughout Los Angeles. When you call (323) 970-3113, you are reaching a local contractor, not a call center. We handle all permit requirements for any major work, so you don't have to worry about the paperwork.
Common Mistakes Homeowners Make
The biggest mistake I see is neglecting annual maintenance. A simple tune-up in March or April can prevent the most common failure modes. Another mistake is ignoring small signs like uneven cooling or a slight increase in your electric bill. These are often early warnings that your system is struggling with a dirty coil or a refrigerant leak. Catching these early saves you money on emergency repairs.
Health and Safety Considerations
Your HVAC system is responsible for the air you breathe. Dirty coils and clogged drains can lead to mold and musty smells in your home. We ensure your system is clean and draining properly. Furthermore, all our work is done in compliance with CSLB standards to ensure your home's electrical and mechanical systems are safe and up to code.
Is It Time for a New System?
If your system is constantly running but failing to cool, or if your energy bills have spiked, it is time for a professional look. We don't push for replacement unless it is truly the most cost-effective option for you in the long run.
If you are adding central AC to a home that never had it, we assess the feasibility of ductwork installation versus the benefits of a multi-zone mini-split system. We look at your home's structure and your comfort goals to give you the best advice.
How the visit works
We perform a full system inspection to diagnose the issue or assess your home for a new installation.
You receive a flat written estimate before any work begins.
We complete the repair or installation using manufacturer-grade standards and pull all required permits.
We test the system through a full cycle to ensure proper airflow and cooling in every room.
Cost factors we review before quoting
- • System size (tonnage)
- • Efficiency rating (SEER2)
- • Ductwork condition and accessibility
- • Complexity of the repair or installation

What Los Angeles customers say about central ac service
Verified reviews from homeowners in Los Angeles and nearby neighborhoods who used our central ac service service.
“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.”
“Had LC install a Daikin mini split in our 1940s bungalow that never had AC. The work was clean, the unit is incredibly quiet, and our bedroom finally stays cool in summer. Highly recommend.”
