Noisy air conditioners can be annoying. Loud or strange sounds from your AC indicate that something is wrong with the cooling system, which may require replacement or repair. Ignoring these loud, squeaking, or buzzing sounds could worsen the problem, leading to costly repairs or replacement. If your AC is producing rattling or other weird sounds, here are some of the possible causes.
Old or Slipped Belt
The squealing noise you hear from your air conditioner could be due to a slipped belt. The belt connects the engine to the AC compressor. An old belt squeals right before it becomes completely malfunctioned. You may require the services of an HVAC technician if the belt subsequently snaps.
Worn-out AC components are often the cause of air conditioners producing weird sounds. However, an electrical problem could also be the cause of a buzzing sound in the house. It could indicate a fault in the electrical system of your air conditioner. A clicking noise could also be a sign of issues with the system relays. It’s not advisable to try fixing electrical problems by yourself. Call a professional HVAC technician to resolve the issue and get rid of the clicking or buzzing noise.
Rattling noises from your air conditioner could be due to loose screws or AC components. You can tell how loose the component is by listening to the intensity of the noise. The louder the rattling noise, the more out of place a component is. Therefore, don’t delay calling a professional if you hear a loud rattling sound before it damages the entire cooling system.
A refrigerant leak is to blame if you’ve noticed a hissing noise coming from your air conditioner. Leaking refrigerant also causes the AC to turn on more frequently without cooling down your home as it should. Ensure that you contact an experienced HVAC technician to discover the refrigerant leak source, fix it, and recharge the AC.
