A » A continuously running HVAC fan may indicate a malfunction or incorrect settings. Check the thermostat mode; it should be set to "Auto" instead of "Fan On." If the issue persists, inspect the system for a stuck relay or faulty limit switch, which may require professional repair. Regular maintenance can prevent such problems and ensure efficient operation. Consulting an HVAC technician is advisable for accurate diagnostics and solutions.
