Common Mini-Split Problems We Fix

Ductless systems are reliable, but like any mechanical equipment, they can experience issues. Our Alpharetta technicians are equipped to handle a comprehensive range of mini-split failures. If you notice any of the following signs, it’s time to call a professional.

System is Running But Not Cooling or Heating

This is one of the most common complaints. You can hear the unit running, but the air coming out is room temperature or not conditioned enough.

• Likely Causes: The most frequent culprit is a refrigerant leak, which reduces the system's ability to transfer heat. Other causes include dirty filters or coils restricting airflow, a failing compressor, or a malfunctioning thermostat that isn't communicating correctly with the unit.
• Our Solution: We perform meticulous electronic leak detection to find and seal any leaks before recharging the system to the manufacturer’s specifications. We also provide thorough coil cleaning and can expertly diagnose and replace faulty compressors or thermostats.

Water Leaking from the Indoor Unit

Discovering a puddle of water beneath your indoor air handler is alarming and can cause property damage if not addressed quickly.

• Likely Causes: This issue is almost always caused by a clogged condensate drain line. When humidity is removed from the air, it collects and is supposed to drain outside. If the line is blocked with algae or debris, the water backs up and overflows. In some cases, frozen evaporator coils can also cause leaking as they thaw.
• Our Solution: Our technicians will safely clear the clog in your condensate line using specialized tools, ensuring proper drainage is restored. We will also investigate the cause of any coil freezing to prevent a recurrence.

Strange or Loud Noises

Your mini-split should operate almost silently. Grinding, rattling, buzzing, or hissing sounds are clear indicators of an internal problem.

• Likely Causes: A grinding noise often points to worn-out motor bearings. Rattling can be caused by loose components or debris in the unit. Hissing typically signals a refrigerant leak, while a buzzing sound may indicate an electrical issue or a failing capacitor.
• Our Solution: We will carefully inspect the unit to identify the source of the sound. This involves tightening loose parts, replacing worn bearings, repairing refrigerant lines, and addressing any electrical faults to restore quiet operation.

Unit Will Not Turn On

If your mini-split is completely unresponsive, the problem is often electrical in nature.

• Likely Causes: The issue could be as simple as a tripped circuit breaker. However, it can also stem from a faulty power supply to the unit, a malfunctioning control board, a blown fuse within the system, or a broken thermostat.
• Our Solution: Our technicians perform systematic electrical diagnostics to trace the power flow, test components like capacitors and control boards, and safely restore power to your system. We never recommend homeowners attempt to diagnose electrical issues on their own.

Unpleasant Odors from the Vents

A musty or sour smell coming from your unit indicates the presence of mold or mildew.

• Likely Causes: The dark, damp environment of the indoor coil and drain pan is a perfect breeding ground for organic growth. When the fan turns on, it circulates these smelly spores throughout your room.
• Our Solution: We offer deep cleaning services that safely remove mold and mildew buildup from the coils, blower wheel, and drain pan, eliminating the source of the odor and improving your indoor air quality.
