What are those sounds coming from my unit and what do they mean?
The buzzing noise could be due to several factors, such as a faulty contactor or contactor switch in the AC compressor, or damage to one of the compressor's legs causing vibrations. Other possible causes include a refrigerant leak, a failing capacitor, or damaged fan blades leading to an imbalance.
The rattling noise from your unit could result from debris in the outdoor unit, a misaligned fan, a faulty motor, or a loose panel door.
The high-pitched whistling noise you're hearing could be coming from an air vent or air handler, often due to restricted airflow. This restriction can be caused by various factors, such as limited ductwork, blocked intake vents, or dirty air filters that need to be cleaned or replaced.
The noise is often caused by broken components, such as a failing motor, a damaged indoor fan, or the compressor itself.
