The answer to 'why is my ductless system' is that there can be several common causes for issues with a ductless HVAC system. Some of the most frequent problems include refrigerant leaks, compressor failures, frozen coils, and electrical issues. Symptoms may include the system not cooling or heating properly, strange noises, or even complete system failure.
In many cases, troubleshooting and repairing a ductless system requires specialized knowledge and tools. While some minor tasks like cleaning the air filters may be DIY-friendly, most repairs should be handled by a licensed HVAC technician to ensure safety and proper system function.
