It can be a bit unnerving when your air conditioner starts making strange noises. It could be a sign of a serious problem, so it's important to take action right away. A knocking or rattling sound coming from either the indoor or outdoor unit could indicate that there are loose parts. This could be caused by the fan blades being loose or something inside the compressor.
If you hear a loud hum, vibration, or click, it could be an electrical issue. This should be addressed by a professional HVAC technician as soon as possible. If you hear a loud noise coming from inside the unit, it could be due to a fault in the fan motor or an unbalanced motor. Replacing the motor can be expensive, so it's best to contact a specialist to better understand the situation. A high-pitched whistle suggests that something is blocking the flow of air in the ducts or ventilation ducts.
Make sure that the vents have enough space to work without being clogged by furniture, dust, or dirt. When buzzing sounds are due to problems in the outdoor air conditioner equipment, professional repair service is guaranteed to replace the compressor or repair damaged or loose parts. No matter what type of noise your AC unit is making, it's important to take action right away. If you're not sure what's causing the noise, contact a professional HVAC technician for help. They will be able to diagnose and repair any issues quickly and efficiently.
