Common Mini-Split Problems We Solve

Ductless systems can experience unique issues that differ from traditional central air units. If you notice any of the following signs, it’s time to call for a professional diagnosis and repair.

• Mini-Split is Not Cooling or Heating Effectively One of the most common complaints is a unit that runs but fails to change the room's temperature. You might feel weak airflow or air that isn't cold or hot enough. This can be caused by several factors, including dirty filters, low refrigerant levels due to a leak, or a problem with the compressor. Our technicians will perform a comprehensive diagnostic to pinpoint the cause, whether it requires a thorough cleaning, precise refrigerant leak detection and recharge, or compressor repair.
• Water Leaking from the Indoor Unit Discovering water dripping from your indoor air handler is alarming. This is typically caused by a clogged condensate drain line, which prevents moisture collected during the cooling process from draining properly. It can also be a sign of a frozen evaporator coil. We will professionally clear the drain line, inspect for underlying causes of freezing, and ensure your system’s drainage is functioning perfectly to prevent water damage and mold growth.
• Strange Noises Coming from Your System Your mini-split should operate almost silently. If you start hearing unusual sounds like grinding, rattling, buzzing, or hissing, it’s a clear indicator of a mechanical problem. A grinding noise could signal a failing motor bearing, rattling may indicate loose components or debris in the unit, and hissing often points to a refrigerant leak. Ignoring these sounds can lead to a complete system failure. We can quickly diagnose the source of the noise and perform the necessary repairs to restore its quiet operation.
• The Mini-Split Will Not Turn On If your unit 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 indicate a more serious problem, such as a faulty power supply, a disconnected wire, or a failed control board. Our technicians will safely trace the electrical connections, test the components, and resolve the power issue to get your system back online.
• Unpleasant Odors from the Vents A musty or moldy smell coming from your mini-split is a sign of bacteria and mildew buildup on the indoor unit's coils and in the drain pan. This not only creates an unpleasant environment but can also negatively impact your home's air quality. Our deep cleaning process involves safely removing and cleaning the essential components, applying antimicrobial treatments to eliminate mold and bacteria, and leaving your air fresh and clean.
• Error Codes on the Display Modern mini-splits are equipped with self-diagnostic systems that display error codes when a fault is detected. While helpful, these codes often require professional interpretation to understand the root cause. Our technicians are familiar with the error codes for all major mini-split brands and can use this information to expedite the diagnostic and repair process accurately.
