Mini split systems are the fastest-growing HVAC solution in Los Angeles — and for good reason. They require no ductwork, heat and cool individual rooms, run quietly, and can be up to 40% more efficient than central systems in some configurations. LC Heating & Air installs all major ductless brands and sizes systems correctly for LA's climate conditions. Single-zone for a bedroom or garage; multi-zone for a whole house without ducts.
I'm Leo, owner of LC Heating & Air. I spend my days helping homeowners in Los Angeles figure out how to keep their houses comfortable without tearing open walls to install ductwork. If you have an older home, a garage conversion, or an ADU, you already know that traditional central air isn't always the right fit. That is where mini splits come in.
A mini split system is essentially a heat pump that connects an outdoor unit to an indoor head through a small, three-inch hole in the wall. It is clean, quiet, and highly efficient. Whether you are looking to cool a single home office or replace an aging furnace and AC with a multi-zone system, my team and I handle the design, electrical, and installation from start to finish.

Why Mini Splits Work for LA Homes
Los Angeles is ideal territory for ductless mini split systems. The city has an enormous stock of pre-1950s homes — Craftsman bungalows, Spanish Colonials, Victorian-era residences — that were built before central air conditioning existed and whose wall construction makes adding new ductwork prohibitively expensive or architecturally destructive. Mini splits solve this problem entirely: a small hole through the wall connects the indoor air handler to the outdoor condenser, with no ductwork required.
Mini splits also excel in newer construction scenarios: ADUs and garage conversions are among the most common mini split applications in LA, since these structures either lack HVAC entirely or have systems that cannot be extended to a new space economically. Sunroom additions, bonus rooms, home offices, and studio spaces are also prime candidates — a mini split provides precise temperature control for a space that would otherwise require expensive ductwork extension.
Mini Split vs Central AC: Which Is Right for Your LA Home?
The choice between a mini split system and central AC depends on your home's existing infrastructure, your cooling needs, and your budget. If your home already has ductwork in good condition, a central AC system is usually the most cost-effective option because the ductwork infrastructure is already in place. If your home lacks ductwork — as many pre-1950s LA homes do — a mini split system eliminates the $5,000-$15,000 cost of new ductwork installation.
Mini splits offer several advantages over central systems regardless of ductwork status. Zone control allows different rooms to be set to different temperatures — no more cooling empty bedrooms while you work in a home office. Inverter compressor technology in mini splits adjusts output continuously, maintaining temperature within ±1°F while using less electricity than the on/off cycling of conventional central AC. And because mini splits deliver conditioned air directly to each room without passing through ducts, there's no duct leakage loss.
ADU & Garage Conversion HVAC
Los Angeles's ADU boom has made mini split installation one of our most-requested services. Every habitable ADU requires a heating and cooling system, and mini splits are the default HVAC solution for ADU construction because they're compact, efficient, and can be installed quickly.
For a typical 400-600 square foot garage conversion or backyard ADU, a single-zone Daikin or Mitsubishi mini split provides both heating and cooling. The installation includes a wall-mounted indoor head, a compact outdoor condenser unit, refrigerant line set, electrical circuit from the main panel, condensate drain routing, and all required permits. Most single-zone ADU installations are completed in one day.
The Decision: Repair or Replace?
When I visit your home, I don't just look at the equipment. I check access, electrical capacity, duct condition, and airflow. If your current system is worth repairing, I will tell you. If the pattern of failures suggests that a replacement is the more honest, long-term financial choice, I will explain why.
With mini splits, the decision is often driven by efficiency and the cost of ductwork maintenance. If you are constantly paying for repairs on an old, leaky ducted system, moving to a ductless mini split can stop the cycle of wasted energy and comfort issues.
Investment and Rebates
We believe in transparency. A single-zone mini split typically ranges from $3,500 to $6,500 depending on the BTU requirements. For whole-house multi-zone systems, costs range from $8,000 to $22,000. These prices include the equipment, labor, and the necessary electrical and refrigerant connections.
California offers significant incentives for heat pump mini splits. SCE rebates can reach up to $1,200 per ton, and TECH Clean California incentives can provide up to $3,000. My team handles the paperwork for these rebates so you don't have to worry about the administrative side of the installation.
How We Work
We don't believe in high-pressure sales. We start with a site assessment to evaluate wall locations, electrical panel capacity, and outdoor unit placement. Once we design the system, we provide a written estimate. When you are ready, we schedule the installation, which usually takes one to two days for most residential projects.
We are a local Los Angeles contractor, licensed and insured (CSLB #1073586). We show up on time, respect your home, and make sure you know how to use your new system before we leave.
Safety and Comfort
Airflow and condensate drainage are critical for indoor air quality. Poorly installed mini splits can lead to water leaks or mold if the condensate lines aren't routed correctly. We ensure every system is installed to code, with proper drainage and secure mounting, keeping your home safe and comfortable year-round.
Because mini splits are heat pumps, they provide both heating and cooling. This is perfect for LA's mild winters and hot summers, giving you a single, reliable system that handles all your comfort needs.
Common Questions
We hear these questions often during our site visits. If you have a specific concern about your home, just ask.
Is a Mini Split Right for You?
If you are tired of window units, noisy central systems, or rooms that never seem to reach the right temperature, a mini split is likely the best path forward. It is a modern, quiet, and efficient way to manage your home's climate.
Call LC Heating & Air at (323) 970-3113 to discuss your project. We will come out, look at your space, and give you an honest assessment of what it will take to get you comfortable.
How the visit works
We evaluate wall locations, electrical panel capacity, and outdoor unit placement for optimal performance.
We calculate room-by-room loads and select the right number of indoor heads and outdoor unit capacity.
We mount indoor heads, install the outdoor unit, run refrigerant lines, and make all electrical connections.
We test the system in both heating and cooling modes, then walk you through the remote and Wi-Fi controls.
Cost factors we review before quoting
- • Number of indoor zones
- • BTU capacity requirements
- • Electrical panel upgrades
- • Mounting complexity for outdoor units
- • Distance between indoor and outdoor units

What Los Angeles customers say about mini split installation
Verified reviews from homeowners in Los Angeles and nearby neighborhoods who used our mini split installation service.
“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.”
“We converted our garage into an ADU and needed HVAC. LC installed a Mitsubishi single-zone mini split — permits, electrical, everything. The unit is so quiet you can barely hear it running. Our tenant loves it.”
“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.”
