Common Signs Your Ductless AC Needs Service
Hot Spots or Warm Airflow
Your system should cool evenly. If not, it could be refrigerant loss or airflow imbalance—we’ll get it back on track.

Water Leaks or Moisture Problems
Leaks can lead to mold and water damage. We inspect, drain, and clean to keep your system dry and safe.
Unresponsive Remote or Thermostat
If your remote won’t control the system, the issue might be IR sensor failure or wiring problems. We’ll sort it quickly.
