It isn’t uncommon to hear noises coming from your air conditioner throughout the day. From sounds when the system turns on to the settling of the system when it turns off, some noises are a normal part of everyday function. However, some air conditioner noises may indicate problems within the system, making it essential that you know how to identify every day and abnormal sounds.
At Genuine Comfort, we understand how frustrating it can be to deal with persistent noises from your air conditioner, especially if these are new noises. But, figuring out the cause of the noises can be difficult to do on your own. If you are experiencing new and unexpected air conditioner noises and you aren’t sure what the cause is, keep reading to see what the problem may be.
1. Banging or Clanking
While some air conditioner noises are expected while the system runs, banging and clanking sounds might indicate a problem. These sounds often point to the presence of loose or broken components, such as a fan blade, compressor part, or motor. Ignoring these signs could exacerbate the problem, potentially leading to more extensive damage and a shortened lifespan for your AC unit. As soon as these sounds begin, it is best to reach out to your trusted HVAC professional for system maintenance to ensure optimal performance and longevity of the system.
2. Hissing
Hissing air conditioner noises often signal ductwork or refrigerant line issues, which most often indicate leaks in the system. These leaks can reduce your system’s cooling efficiency, leading to higher energy bills. Additionally, refrigerant leaks pose health risks and environmental concerns. Prompt maintenance by a professional is essential to address these issues. They can locate and repair leaks, ensuring your system operates efficiently while minimizing health and environmental hazards. Addressing leaks not only maintains cooling performance but also protects against increased energy costs and potential health risks.
3. Grinding or Screeching
Grinding or screeching air conditioner noises may indicate underlying issues within the motor or blower assembly. These distressing noises could stem from several sources, including worn-out bearings, a malfunctioning belt, or insufficient lubrication. Each of these problems can exacerbate the friction and strain on components, leading to more extensive damage if left unaddressed. Continuing to operate the AC when it makes these noises may even result in complete system failure. It’s essential to heed these warning signs and seek professional assistance promptly to prevent further deterioration.
4. Clicking
While occasional clicking sounds when your air conditioner turns on and off are normal, persistent clicking or buzzing noises could hint at underlying electrical issues. These air conditioner noises might come from a defective capacitor or loosely connected electrical components. Ignoring these warnings could escalate into a potentially hazardous situation, as unchecked electrical problems pose a heightened risk of home fires. It’s essential to reach out to an HVAC professional as soon as possible to correct any electrical issues, ensuring the system is safe to run in your home.
5. Rattling or Vibrating
Rattling or vibrating air conditioner noises are typically caused by loose or improperly secured components in the system. These may include loose screws, misaligned fan blades, or debris lodged within the unit. Although these noises might not indicate a larger problem in the system, they can increase wear and tear on the AC unit if neglected. Over time, this increased strain could lead to more severe problems, potentially compromising the efficiency and longevity of the system. If you hear rattling or vibrating, it is best to speak to a professional to ensure your system can function properly.
6. Chattering
Chattering air conditioner noises may mean there is a problem with the system’s contactor. The contactor is responsible for controlling the flow of electricity to the the compressor and condenser fan motor. When the contactor is faulty or worn out, it may produce chattering sounds as it struggles to make a consistent connection. Ignoring these chattering noises can lead to further deterioration of the contactor, potentially resulting in electrical failure or system shutdown. If you notice chattering noises coming from your air conditioner, it’s essential to have the contactor inspected and replaced by an HVAC technician.
