Our professional technicians have the skills, knowledge, and tools to fix most mini-split problems right on the spot – quickly and correctly. Mini-split systems, also known as ductless mini-split systems, are complex and require our specialized knowledge to diagnose and fix issues correctly. Here are the steps typically involved in mini-split repairs:
Our technician will start by assessing the problem. This might involve talking to you to understand any symptoms or issues you’ve noticed, such as unusual sounds, weak airflow, or temperature inconsistencies. They will also inspect the indoor and outdoor units of the mini-split system.
Before starting any repairs, the technician will turn off the power supply to the mini-split system to ensure safety. Working with electrical components can be dangerous, so proper precautions are essential.
Our technician may use specialized tools to test various components of the mini-split system, such as the compressor, fan, thermostat, and refrigerant levels. They will identify the specific issue causing the malfunction.
Depending on the diagnosis, JW Heating & Air technicians will repair or replace the faulty components. This might include fixing refrigerant leaks, replacing capacitors or relays, cleaning or replacing air filters, or repairing electrical connections
Cleaning the indoor and outdoor units is an essential part of mini-split maintenance. Dust, debris, and dirt can accumulate on the evaporator and condenser coils, reducing the system’s efficiency. The technician will clean these components thoroughly.
If the refrigerant levels are low due to a leak, our specialized technician will identify and repair the leak before adding the correct amount of refrigerant to the system.
After making the necessary repairs, the technician will test the mini-split system to ensure it is working correctly. They will also calibrate the thermostat and ensure proper airflow.
The technician will perform a final inspection to ensure that all components are functioning correctly and that the system is operating efficiently.

If your mini-split is not cooling effectively, it could be due to a dirty filter, low refrigerant levels, or a blocked outdoor unit. Be sure to check and clean the filters regularly, and if the problem persists, call (213) 374-0009 for further inspection.
Water leakage can happen if the condensate drain line is clogged or if your unit is not properly leveled. High humidity during the Los Angeles, CA summer months can exacerbate this issue. Try cleaning the drain line or adjusting your unit’s position to resolve the problem. If that still doesn’t do the trick, call your local cooling experts at JW Heating & Air to schedule a prompt mini-split repair.
If your mini-split is blowing warm air during summer, there may be a problem with the refrigerant level, a malfunctioning compressor, or issues with the thermostat settings. A certified JW Heating & Air technician can diagnose and fix the issue quickly.
This could be caused by dirty sensors, a faulty thermostat, or an electrical issue. It’s always a good idea to check for simple fixes like cleaning sensors, but for more complex problems, a professional assessment is recommended.
A slight increase in noise is to be expected during high usage, but unusual or loud sounds like banging or screeching often signals an issue with the fan, motor, or internal components. Contact our team at (213) 374-0009 if you notice any unfamiliar noises.
