Ignoring condenser fan problems can lead to reduced system performance, increased energy consumption, and even complete system failure. Inefficient heat rejection can cause the compressor to work harder, resulting in increased energy bills and reduced system lifespan. Moreover, neglected condenser fan issues can lead to refrigerant leaks, compressor damage, and safety hazards. It is essential to address condenser fan problems promptly to ensure optimal system performance, energy efficiency, and safety.
