Fast, honest mini split diagnosis and repair for all brands. We provide clear, written estimates before starting any work to help you decide on the best path for your home.
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 to tell you exactly what is wrong and whether it is worth fixing. In Mid-City, I see a mix of homes ranging from older single-family houses to newer remodels, and I have worked on every major brand including Mitsubishi, Daikin, Fujitsu, LG, and Samsung.
My approach is simple: I show up, I diagnose the issue, and I give you a written estimate. If the system is worth repairing, I will fix it right. If the pattern of failure suggests that replacement is the smarter long-term move, I will explain why. We are licensed (CSLB #1073586) and ready to help.

Common Mini Split Issues in Mid-City
In our area, the most frequent calls I get involve units that blow air but don't actually cool or heat. This is often a refrigerant leak or a reversing valve failure. Because of the dust and the way these systems are installed in local remodels, I also see a lot of clogged condensate drains and dirty blower wheels that restrict airflow and cause the system to short-cycle.
Another common issue is a flashing error code on the indoor head. Every manufacturer has their own diagnostic language. Rather than guessing, I use the specific service manuals for your brand to interpret the code. Whether it is a communication error between the indoor and outdoor units or a sensor failure, I will identify the fault before we talk about a repair.
Working with Mid-City Homes
Mid-City housing is diverse. Whether you are in a classic single-family home or a modern multifamily unit, the way your mini split is installed matters. I pay close attention to line-set routing, electrical capacity, and how the indoor head is placed.
Before recommending a repair, I check the basics: is the unit getting proper airflow? Is the drainage clear? Is the electrical connection solid? These details matter because they change the repair decision. A system that is installed correctly lasts longer, and I want to make sure your repair addresses the root cause, not just the symptom.
My Diagnostic Process
I don't believe in guesswork. When I arrive at your home, I start by reading the error codes and inspecting the physical condition of the indoor and outdoor units. I check refrigerant levels, test the drain line, and look at the electrical connections.
Once I know what is wrong, I write down an estimate. You will know the cost before I turn a wrench. My goal is to give you the information you need to make an informed decision about your equipment.
Repair or Replace?
This is the most important conversation we can have. If your mini split is 15 to 20 years old and the compressor is failing, it might be time to look at a new, more efficient system. However, if it is a simple drain clog, a sensor issue, or a minor refrigerant leak, a repair is usually the right choice.
I will never push you to replace a unit that has plenty of life left. I will give you an honest assessment of the repair cost versus the value of the system. If the repair is expensive, I will tell you why, and we can look at the numbers together.
Repair Costs
I keep my pricing straightforward. A diagnostic visit typically ranges from $125 to $175. Common repairs like clearing a condensate drain usually fall between $100 and $175, while more complex jobs like refrigerant leak repair or control board replacement range from $250 to $650.
Every home is different, which is why I provide a written estimate for your specific situation. No surprises, no hidden fees.
Scheduling Service
I know that when your AC is down in the LA heat, you want it fixed quickly. I carry common parts for most major brands, which allows me to handle many repairs on the same day. If you are in Mid-City or the surrounding areas, give me a call at (323) 970-3113 to see when I can get out to you.
I respect your time and your property. I will coordinate with you on access and make sure I leave your home as clean as I found it.
Mistakes to Avoid
The biggest mistake I see is ignoring small issues. A dripping indoor head might seem like a minor annoyance, but if you let it go, it can trip a float switch and shut down the whole system. Another mistake is trying to reset error codes without fixing the underlying problem. A reset might get the unit running for a few hours, but if the fault is still there, the code will just come back.
If you see an error code or notice a change in how your unit performs, call a professional. It is almost always cheaper to fix a small problem early than to wait for a total system failure.
Health and Safety
Your indoor air quality depends on a clean system. A dirty indoor coil or blower wheel can harbor dust and mold, which then gets circulated throughout your home. During my service visits, I check the condition of these components to ensure your system is blowing clean air.
I also ensure that all electrical connections are secure and that the refrigerant lines are properly sealed. Safety is the priority in every repair I perform.
Making the Right Choice
When you are deciding whether to repair or replace, look at the age of your unit and the frequency of your repairs. If you are calling for service every few months, it is time to talk about a replacement. If your unit is relatively new and this is the first issue, a repair is usually the best value.
I am here to provide the facts so you can make the decision that makes the most sense for your home and your budget.

What Mid-City customers say about mini split repair
Verified reviews from homeowners in Mid-City 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.”
