When your air conditioner is running like it’s supposed to, you won’t hear anything other than a soft hum. In fact, the noise is so minimal that you probably won’t notice it at all. However, when your system starts making strange noises, it’s usually a sign that something is wrong. Keep reading to learn more about some strange AC noises, what they mean, and what you need to do when you hear them.
Banging or Clanking Sounds
When your air conditioner starts making clanking or banging sounds, it usually means that something inside the system is loose or broken. In some instances, it’s something as minor as a twig or branch that has fallen into the fan blades. However, it’s also possible that you have loose or damaged parts and pieces rattling around inside the system.
When you hear banging or clanking sounds, ask a professional technician take a look at your air conditioner. Finding the source of the sound and fixing it can help prevent any further damage.
Buzzing or Humming Noises
A low humming sound coming from your AC is normal. However, when that hum evolves into a persistent buzzing noise, you need to act quickly, as it probably means that you’re dealing with an electrical problem. Even a hum that’s louder than usual can point to issues with the fan motor or relay switch.
Electrical problems not only have the potential to do significant damage to your AC, but they’re also a fire risk. As soon as you notice these sounds, turn your air conditioner off, and call for professional repair.
Clicking at Startup or Shutdown
Your air conditioner should click once when it turns on or off. If you hear persistent, repetitive clicking, you’re probably dealing with problems with your thermostat, control board, or relay. In some instances, fast clicking noises can mean that you have a faulty electrical component.
Hissing or Whistling Noises
Your air conditioner uses a chemical called refrigerant to cool your home. This pressurized chemical travels through tiny tubes inside your air conditioner. Whistling or hissing noises generally mean that you have a refrigerant leak.
You need to call a professional as soon as you detect this sound. Leaking refrigerant not only makes your AC less effective and efficient, but it’s also a safety hazard.
