Boone's mountain climate puts unique demands on ductless mini splits. Here are the most common problems we see and repair:

Refrigerant Leaks: Mini splits use less refrigerant than traditional systems, so even a small leak affects performance. We use electronic leak detectors to find and repair leaks, then recharge to factory specs.

Frozen Indoor Coils: In Boone's cold, damp winters, mini split coils can freeze — especially if the defrost cycle isn't working properly. We repair defrost sensors, thermistors, and control boards.

Drainage Issues: Mini splits dehumidify as they cool, and the condensate needs to drain properly. Clogged drain lines cause water to leak from the indoor unit. We clear lines and install algae tablets to prevent future clogs.

Inverter Compressor Failures: The inverter compressor is the heart of a mini split. If it fails, the system won't heat or cool. We diagnose whether the compressor, inverter board, or a sensor is at fault and recommend the most cost-effective repair.

Communication Errors: Mini splits use communication signals between indoor and outdoor units. A wiring issue or board failure can cause error codes and system shutdown. Our technicians are trained to diagnose and repair these complex electronic issues.
