The answer to 'ductless system short cycling' is that short cycling, where the system turns on and off frequently, is a common problem with ductless HVAC systems. This can be caused by a variety of issues, including low refrigerant levels, a malfunctioning thermostat, or problems with the system's compressor or fan. Short cycling can lead to higher energy bills and increased wear and tear on the system.
To troubleshoot and fix short cycling, you can start by checking the air filters and cleaning or replacing them if they're dirty. You can also check the thermostat to ensure it's functioning properly and set to the correct temperature. If those don't solve the issue, it's best to call a professional HVAC technician to diagnose and repair the problem, as they have the specialized tools and expertise to properly identify and address the root cause.
