Practical, honest mini split repair for Pico-Robertson homeowners. We diagnose, provide a written estimate, and fix your system right the first time.
When your mini split stops working, you need a clear answer, not a sales pitch. At LC Heating & Air, I focus on diagnosing the actual fault—whether it is a simple drain clog, a communication error, or a refrigerant leak. I work on all major brands, including Mitsubishi, Daikin, Fujitsu, LG, and Samsung, right here in Pico-Robertson.
My goal is to give you a straightforward assessment of your equipment. If a repair makes sense, I will tell you. If the system is at the end of its life or the repair cost outweighs the value, I will explain why. You deserve a system that works reliably, and that starts with an honest diagnostic process.

Honest diagnosis and quality repair
Common Mini Split Issues in Pico-Robertson
In our neighborhood, I see a lot of the same issues. Because Pico-Robertson has a mix of older single-family homes and newer multifamily units, mini splits often deal with dust and heavy usage. The most common call I get is for a unit that blows air but doesn't cool or heat. This usually points to a refrigerant leak or a reversing valve failure.
Another frequent issue is water dripping from the indoor head. This is almost always a clogged condensate drain line. It is a quick fix, but if left alone, it can trip the float switch and shut your system down entirely. I also see many communication faults caused by electrical issues or damaged wiring between the indoor and outdoor units, which is common in older homes undergoing renovations.
Working with Pico-Robertson Homes
Pico-Robertson has a unique mix of housing, from older bungalows to modern duplexes and small apartment buildings. When I look at a mini split installation, I have to consider the building's age, the existing electrical capacity, and how the line sets were routed. If your home has been remodeled, the original HVAC design might not match the current layout, which can affect airflow and performance.
Before I recommend any repair, I check the access to the unit, the condition of the ducting (if applicable), and the placement of the equipment. A system that is tucked into a tight space or has poor airflow will always struggle. I look at these factors so that when I fix your system, it actually stays fixed.
My Diagnostic Process
I don't guess. When I arrive at your home, I start by reading the manufacturer's error codes. These codes are the system's way of telling us exactly what is wrong, whether it's a sensor failure, a fan motor issue, or a communication fault. I have the service manuals for all major brands, so I can interpret these codes accurately.
After checking the electronics, I inspect the refrigerant circuit using electronic detectors to find leaks, check the condensate drain for clogs, and verify the electrical connections. Once I know exactly what is wrong, I write up an estimate. You will know the cost before I turn a single wrench.
Repair or Replace?
This is the most important decision a homeowner makes. If your mini split is 15 to 20 years old and the compressor fails, replacement is usually the smarter choice. However, if you have a newer unit with a simple drain clog or a faulty sensor, a repair is the right path.
I will never push you to replace a system that has plenty of life left. I look at the cost of the repair versus the age and condition of the unit. If the repair is expensive, I will show you the numbers so you can decide if it is worth the investment or if it is time to upgrade to a more efficient system.
Understanding Repair Costs
I believe in transparency. My diagnostic fee is $125–$175. Once I identify the problem, I provide a flat-rate repair price. For example, clearing a condensate drain typically runs $100–$175, while a refrigerant leak repair and recharge ranges from $250–$500. Control board replacements or reversing valve repairs are more involved and range from $350–$650.
These prices cover the labor and the parts needed to get your system back in shape. I don't hide costs or add surprise fees. You get a written estimate, and we move forward only when you are comfortable with the plan.
Scheduling Your Service
I know that when your AC goes out in the LA heat, you don't want to wait days for a technician. I carry common mini split parts on my truck, which allows me to handle many repairs on the same day. I serve the entire Pico-Robertson area and surrounding neighborhoods like Beverlywood and Miracle Mile.
To get started, give me a call at (323) 970-3113. I will ask a few questions about what the unit is doing and when it started, and we will find a time that works for you. I am a licensed C-20 contractor (CSLB #1073586), so you can be sure the work is done to code.
Mistakes to Avoid
The biggest mistake I see is ignoring the small signs. A unit that drips a little water or makes a faint clicking noise is trying to tell you something. If you ignore it, a $150 drain cleaning can turn into a $500 repair because the water damaged the control board or the motor.
Another mistake is trying to reset the system repeatedly without fixing the fault. Turning the breaker off and on might clear the error code for a few minutes, but if the underlying issue—like a refrigerant leak—isn't fixed, the system will just keep failing. Let me diagnose it properly so you don't end up with a bigger bill later.
Health and Safety
Your indoor air quality depends on your HVAC system. A dirty indoor coil or a clogged drain pan can become a breeding ground for mold and bacteria, which then gets circulated through your home. Keeping your filters clean and your coils serviced is not just about cooling; it is about the air you and your family breathe.
I also ensure that all electrical connections are secure and that the system is operating within safe pressure limits. If I find a safety issue during my inspection, I will point it out immediately. My job is to make sure your home is comfortable and safe.
Is Your Mini Split Worth Repairing?
If your system is less than 10 years old and has been well-maintained, a repair is almost always the right move. Most major brands like Mitsubishi and Daikin are built to last, and parts are readily available. If the unit is older and the repair cost is significant, we should talk about the long-term value of a new, high-efficiency system.
I will look at your specific situation—the age of the unit, the frequency of repairs, and the overall performance—and give you my honest recommendation. I am here to help you make the decision that makes the most sense for your home and your budget.

What Pico-Robertson customers say about mini split repair
Verified reviews from homeowners in Pico-Robertson 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.”
