Fast, honest mini split diagnosis and repair for all brands. We provide clear, written estimates before starting any work to help you decide between repair and replacement.
I’m Leo, owner of LC Heating & Air. If your mini split is acting up, you don't need a sales pitch—you need someone who knows how to read the error codes, find the leak, or clear the drain line so you can get back to being comfortable. I’ve been working on these systems across Los Angeles for years, and I’ve seen just about every way they can fail.
Whether you're in an apartment, a condo, or a house in the Fairfax District, these systems are great until they aren't. My goal is to give you a straight answer about what’s wrong. If it’s a simple fix, we’ll get it done. If the system is on its last legs, I’ll tell you that too, so you aren't throwing good money after bad.

Common Mini Split Issues in Fairfax
In our neighborhood, I see a lot of the same problems. Because we have so many older multifamily buildings and compact mechanical spaces, airflow is often restricted. If you notice your unit turning on and off repeatedly, it’s often just a dirty filter or a clogged coil preventing the system from moving air properly.
Water dripping from the indoor head is another classic call. It’s almost always a clogged condensate drain line. It’s a quick fix, but if it’s ignored, it can trip the float switch and shut your whole system down. We also see plenty of communication errors between the indoor and outdoor units, which can be caused by anything from a loose wire to a failing control board.
Working in Fairfax District Buildings
The Fairfax District has a unique mix of older apartments, condos, and mixed-use buildings. This means our repair process has to account for more than just the machine. We deal with rooftop package units, shared walls, and tight access windows every day.
When I come out to your place, I’m looking at how the system was installed. If the line-set routing is cramped or the outdoor unit is tucked into a spot with poor ventilation, that affects how the system runs. I’ll check the electrical capacity and the drainage setup to make sure we aren't just fixing a symptom, but actually solving the problem.
Our Diagnostic Process
I don't guess. When I arrive, the first thing I do is read the error codes. These systems are smart enough to tell us exactly what’s wrong, provided you have the right manual and the experience to interpret them. I’ll check your refrigerant levels, inspect the electrical connections, and look at the condition of your blower wheel and coils.
Once I’ve identified the fault, I’ll sit down with you and explain what I found. You’ll get a written estimate for the repair before I touch anything. No surprises, no hidden fees—just a clear explanation of what needs to happen to get your system running again.
Repair vs. Replacement
This is the most important conversation we have. A well-maintained mini split from a quality brand like Mitsubishi or Daikin can last 15 to 20 years. If your unit is relatively young and the repair is a straightforward part replacement, it’s usually worth fixing.
However, if I find that the compressor is failing or the refrigerant leak is in a spot that’s impossible to reach without tearing out a wall, I’m going to be honest with you. In those cases, replacement is the smarter long-term move. I’m not here to sell you a new system if you don't need one, but I won't let you spend money on a repair that won't last.
What You Can Expect to Pay
I believe in price transparency. A standard diagnostic visit runs between $125 and $175. If it’s a simple drain clearing, you’re looking at $100 to $175. More complex jobs, like replacing a control board or a reversing valve, generally range from $350 to $650.
If you do end up needing a full system replacement, a single-zone install typically runs $3,500 to $6,500, while multi-zone systems can go from $8,000 to $22,000. I’ll always provide a written estimate so you know exactly what the job costs before we start.
Safety and Maintenance
Your HVAC system is a major part of your home’s health. A dirty indoor head isn't just inefficient—it can circulate dust and allergens throughout your living space. We always inspect the coil condition during our service calls.
If your system is leaking refrigerant, that’s a safety issue that needs to be addressed properly. We use electronic detectors to find the leak, not just top off the refrigerant. Doing it right keeps your home safe and ensures your system doesn't break down again in a month.
Mistakes to Avoid
The biggest mistake I see is ignoring the small stuff. If your unit is making a strange noise or dripping a little water, don't wait for it to stop working entirely. A small, inexpensive repair today is almost always cheaper than a major component failure tomorrow.
Another mistake is trying to reset error codes without fixing the underlying issue. Turning the breaker off and on might clear the light, but it doesn't fix the problem. If the code comes back, the system is trying to tell you something is still wrong. Listen to it, and give us a call.
Scheduling Your Service
I know how busy life in the Fairfax District can be. Whether you’re coordinating with an HOA, managing a tenant, or dealing with limited parking, we work with you to make the scheduling process as smooth as possible.
We carry common parts for all major brands, so we can often handle repairs on the same day. Give us a call at (323) 970-3113, and let’s get your system back in shape.
Is It Time for a Repair?
If your mini split is under 10 years old and the repair is a specific component like a fan motor or a control board, it’s usually a solid candidate for repair. These are high-quality machines, and they are designed to be serviced.
If you’re finding that you’re calling for repairs every few months, or if the cost of the repair is approaching a significant percentage of a new unit, we should talk about replacement. I’ll give you the facts, and you can make the decision that makes the most sense for your home and your budget.

What Fairfax District customers say about mini split repair
Verified reviews from homeowners in Fairfax District 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.”
