When your ductless system isn’t responding to commands or is cooling erratically, the issue often lies in the thermostat or onboard sensor. We’ll check for wiring issues, failed sensors, or poor calibration. If your mini-split won’t turn on or cool properly, we’ll trace the fault and restore accurate control
Ductless systems use sealed refrigerant lines that run between the indoor and outdoor units. If a line cracks or wears out, you’ll notice poor performance, reduced cooling, or complete failure. We offer full leak detection, repair, and recharging for ductless systems using the correct refrigerant type and pressure.

If the indoor air handler is buzzing, clicking, or not blowing any air, the fan motor may be worn out or stuck. We inspect motor bearings, fan wheels, and electrical connections to identify the issue. A fast replacement can get your airflow back to normal without replacing the entire unit.
Drainage or Ice Build-Up
Water leaking from your indoor unit or ice forming on the coil usually points to clogged drain lines or low airflow. These problems can cause major damage over time. We’ll flush the drain, clean the coil, and prevent icing that can strain your compressor or lead to failure.
