Common Mini-Split Problems We Resolve

Ductless systems can exhibit unique symptoms when they aren't working correctly. If you're experiencing any of the following issues, our team has the expertise to find the source of the problem and implement a lasting solution.

Unit is Not Cooling or Heating Effectively

One of the most common complaints is a noticeable drop in performance. Your mini-split may be running, but the air coming out isn’t cold or warm enough. This can be caused by several issues, including low refrigerant levels due to a leak, a malfunctioning compressor, or a faulty reversing valve in the heat pump.

Water Leaking from the Indoor Unit

Discovering a puddle of water beneath your indoor air handler is a clear sign of trouble. This is often caused by a clogged condensate drain line, which prevents moisture from being properly removed from your home. It can also indicate a cracked drain pan or an improper installation, both of which require professional attention to prevent water damage.

Unusual Noises During Operation

Your mini-split should operate with a quiet hum. Loud or strange noises like grinding, rattling, or buzzing are abnormal and point to a mechanical problem. A grinding sound could mean the motor bearings are failing, while rattling may indicate loose components or debris in the unit. Buzzing often signals an electrical issue that needs immediate inspection.

The System Won’t Turn On

If your mini-split is completely unresponsive, the issue could be as simple as a dead battery in the remote or a tripped circuit breaker. However, it can also point to more complex internal problems, such as a faulty control board, a wiring failure, or a compromised power supply to either the indoor or outdoor unit.

Weak Airflow from the Indoor Unit

When the fan is running but the airflow feels weak, it often indicates a restriction somewhere in the system. The most common culprit is a dirty air filter that is blocking air from passing through. It could also be caused by a buildup of dirt and grime on the evaporator coil or a problem with the blower wheel inside the air handler.

Error Codes on the Display

Modern mini-splits are equipped with self-diagnostic systems that display error codes to help identify malfunctions. These codes correspond to specific problems, from sensor failures to communication errors between the indoor and outdoor components. Our technicians are trained to interpret these codes across all major brands to quickly pinpoint the root cause.

Our Comprehensive Mini-Split Repair Process

We believe in a transparent and methodical approach to every repair. When you entrust us with your ductless system, we follow a detailed process to ensure nothing is overlooked and that your system is repaired correctly the first time.

Thorough System Inspection

Our diagnostic process begins with a complete evaluation of your entire mini-split system. The technician will meticulously inspect the indoor air handler, checking the filter, coils, and blower fan for dirt or blockages. We then move to the outdoor condenser unit to examine the compressor, fan, and refrigerant lines for any signs of damage or leaks.

Precise Problem Diagnosis

Using advanced diagnostic tools, we test the electrical components, check refrigerant pressures, and verify communication between the system’s indoor and outdoor units. This detailed analysis allows us to move beyond the symptoms and identify the precise component that has failed. Whether it’s a faulty thermistor, a failing inverter board, or a tiny refrigerant leak, we will find it.

Clear Explanation and Repair Plan

Once we have diagnosed the issue, we take the time to explain our findings to you in clear, understandable terms. We will outline the exact nature of the problem, what is required to fix it, and provide a complete breakdown of the repair plan. We want you to be fully informed and confident in the work being performed before we proceed.

Professional and Lasting Repair

Our technicians carry a wide range of high-quality replacement parts to complete most repairs in a single visit. We use parts and repair techniques that meet or exceed manufacturer specifications, ensuring the integrity of your system is maintained. From repairing a sensitive electronic board to carefully brazing a refrigerant line, every task is performed with precision and expertise.

Final System Testing and Verification

After the repair is complete, we don’t consider the job done until we’ve thoroughly tested the system. We power on your mini-split and run it through a full heating and cooling cycle to confirm that it is operating smoothly, quietly, and efficiently. We verify that airflow is strong, temperatures are accurate, and the problem is fully resolved, restoring total comfort to your space.
