Fast, honest mini split diagnosis and repair for all major brands. We provide clear, written estimates and same-day service across Los Angeles.
I'm Leo, owner of LC Heating & Air. If your mini split system is acting up, you don't need a sales pitch—you need a clear answer on what's wrong and whether it's worth fixing. We service all major brands, including Mitsubishi, Daikin, Fujitsu, LG, Samsung, Carrier, Gree, and MRCOOL, right here in Los Angeles.
My approach is simple: I come out, I diagnose the issue, and I tell you exactly what I find. Whether it's a simple drain clog or a more complex refrigerant leak, I'll explain the repair, give you a written estimate, and let you decide how you want to move forward. We don't guess; we use the manufacturer's diagnostic codes to get to the root of the problem.

Common Mini Split Issues in Los Angeles
In Los Angeles, we see a lot of the same issues. Because of our climate and the way these systems are installed in older homes, we frequently deal with dirty blower wheels, clogged filters, and condensate drain problems. If your unit is dripping water inside, it's almost always a clogged drain line that needs clearing.
We also see communication faults between the indoor and outdoor units, often caused by electrical issues or damaged wiring. If you see an error code flashing on your indoor head, don't ignore it. That code is the system telling us exactly where the fault lies, and we have the service manuals to interpret those codes correctly.
Working with Los Angeles Homes
Los Angeles has a mix of everything—single-family homes, duplexes, and older multifamily buildings. Every property has its own quirks when it comes to HVAC. Before we touch your equipment, we look at your specific setup: how the line sets are routed, where the indoor heads are placed, and whether the electrical capacity is sufficient.
This context matters. A mini split in a newer remodel might have easy access, while one in an older building might be tucked into a tight space. We account for these factors so we can provide a repair that actually lasts, rather than a quick fix that fails again in a month.
Our Diagnostic Process
We don't show up to sell you a new system. We show up to fix the one you have. Our process starts with a thorough inspection: we read the error codes, check your refrigerant levels, inspect the indoor coil and drain, and verify all electrical connections.
Once we identify the failure, we write down a clear estimate. You'll know exactly what the repair costs before we pick up a tool. After the work is done, we run the unit through a full heating and cooling cycle to make sure everything is working as it should.
Repair vs. Replacement: The Honest Truth
A lot of people ask me, 'Leo, is it worth fixing?' The answer depends on the age of the unit, the cost of the repair, and the overall condition of the system. If it's a minor part like a sensor or a drain issue, a repair is almost always the right move. If the compressor has failed on an older unit, or if it's leaking refrigerant in multiple places, we'll have an honest conversation about whether replacement makes more financial sense.
We aren't here to push you toward a new system. We're here to give you the information you need to make a smart decision for your home and your budget.
Repair Costs and Estimates
We believe in transparency. Our diagnostic fee is $125–$175, which covers the time it takes to accurately identify the problem. Common repairs like clearing a condensate drain typically run $100–$175, while more involved work like replacing a control board or fixing a refrigerant leak can range from $250 to $650.
We provide a written estimate for every job. You won't see any surprise fees on your final bill. We want you to feel comfortable with the cost before we start any work.
Scheduling Your Service
We know that when your HVAC goes down, you want it fixed fast. We carry common mini split parts on our trucks, which allows us to handle most repairs in LA County on the same day. Give us a call at (323) 970-3113 to get on the schedule.
When we arrive, we'll respect your property and your time. We check everything from airflow to electrical capacity to ensure that when we leave, your system is running reliably.
Mistakes to Avoid
The biggest mistake I see is ignoring the small signs. A system that turns on and off repeatedly or a unit that is dripping water isn't just a minor annoyance—it's a warning sign. If you ignore these, a $150 repair can quickly turn into a much larger, more expensive problem.
Another mistake is trying to reset an error code without fixing the underlying issue. Clearing the code might make the light stop flashing for a few hours, but it doesn't fix the fault. If the code comes back, it means the problem is still there, and you need a professional to take a look.
Health and Safety
Your comfort and safety are our priority. A mini split that isn't draining properly can lead to mold growth in the indoor head, which affects your indoor air quality. We inspect the coil condition and drainage during every service call to make sure your system is clean and safe.
We are fully licensed (CSLB #1073586) and insured. When you hire LC Heating & Air, you're getting a professional who follows the rules and does the job right the first time.
How to Decide on Your Next Step

If the system is worth repairing, we'll tell you. If the pattern points to replacement, we'll explain why. Either way, you'll have all the facts you need to make the right choice for your home.

What Los Angeles customers say about mini split repair
Verified reviews from homeowners in Los Angeles and nearby neighborhoods who used our mini split repair 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.”
