What To Do If You Hear A Loud noise From Your Air Conditioner

It's midnight and you're just trying to get some sleep when you hear a loud noise coming from your air conditioner. What should you do?

1. Turn off the air conditioner

Don't panic. It's likely that the noise is just a symptom of a simple problem that can be easily fixed. 

If the noise is coming from the outdoor unit, it could be that something has become caught in the fan. Just turn off the power to the unit and remove whatever is blocking the fan. 

If the noise is coming from the indoor unit, it could be that the capacitor has failed. Again, just turn off the power to the unit if needed.

Of course, there's always a chance that the noise could be indicative of a more serious problem. If the noise is accompanied by strange smells or smoke, it's best to turn off the power to the unit and evacuate the area immediately.

2. Check the unit

Rheem air conditioners are famous for their quality, durability, and energy efficiency. But then, like any appliance, they can sometimes make noise. If your Rheem air conditioner is making an unusual noise, there are a few things you can do to determine the cause.

  1. First, check the unit's filters and coils. If they are dirty, they may be causing the unit to work harder than necessary, which can lead to increased noise.
  2. Next, check the condensate drain line to ensure that it is clear. A clogged drain line can cause water to build up in the unit, which can also lead to increased noise.
  3. Then, the fan blades may be hitting something inside the unit. You can usually fix it by simply opening up the unit and readjusting the blades.
  4. Additionally, the compressor may be starting to fail. If it is a more serious problem, it will require a trained technician to fix it.
  5. Besides that, there may be something blocking the airflow through the unit. You can resolve this by simply cleaning or replacing the air filter.

3. Call for a professional

If all else fails on checking the unit, contact a certified Rheem technician for help. They can inspect the unit and make any necessary repairs. Other than that, they will be able to diagnose the problem and recommend a course of action.

By taking action quickly, you can minimize the risk of further damage to your air conditioner and keep it running smoothly for many years to come.

What Are The Sounds Your Rheem Air Conditioner Makes?

It is also important to know the main reason behind the loud noise of your Rheem AC. Here is a compilation of different sounds that your air conditioner may be making, indicating it is time for a repair.

Loud scraping, metal hitting metal sound

A loud scraping, metal hitting metal sound usually indicates that there is something caught in the fan blades. It can be anything from leaves to pieces of dirt and debris. If this is the case, it is important to turn off your air conditioner and remove the obstruction so that the fan blades are not damaged.

Loud thumping or vibrating noise

Another common sound is a clicking noise. This can indicate that there is a loose part in the unit that needs to be tightened or replaced.  Also, make sure that nothing is blocking the fan blades from spinning freely. 

If the blades are clear, the problem may be with the motor itself. Over time, the lubricant in the motor can dry out, causing the motor to overheat and make a thumping noise.

Another possible cause of a thumping noise is an imbalanced compressor. If the compressor is off-balance, it can cause vibrations that transfer throughout the entire unit. 

Loud humming noise

If your air conditioner is making a loud humming or buzzing noise, it could be a sign that there is something wrong with the motor. The motor is responsible for circulating the coolant throughout the system, so if it is not working properly, it can cause the unit to overheat and make a loud humming noise.

Rattling, squealing, or high-pitched sound

A rattling sound is usually the first sign that something is wrong. This is usually caused by a loose part or a build-up of dirt and dust. Besides that, a high-pitched sound is another common sign that your air conditioner needs some TLC. This sound is often caused by a restricted airflow, which can be caused by dirty air filters or a blockage in the vents.

Loud pop or bang sound

If your air conditioner is making a loud pop or bang sound, it's important to take immediate action. This type of noise usually indicates that there is an issue with the unit's compressor. The compressor is responsible for circulating the refrigerant throughout the system, so when it isn't working properly, it can cause all sorts of problems.

Rumbling noises

One common source of air conditioner noise is a rumbling sound. It could be due to loose parts, an imbalanced fan, or a build-up of debris in the unit. While a rumbling noise may not be a cause for alarm, it's important to have it checked out by a professional to ensure that it's not indicative of a more serious problem.

How To Prevent Excessive Noise From Your Air Conditioner In The Future

Excessive noise from your air conditioner can be frustrating and even embarrassing. If you have ever been in a situation where your air conditioner has made too much noise, you know how difficult it can be to concentrate or carry on a conversation. 

There are a few things that you can do to prevent excessive noise from your air conditioner in the future.

  1. First, make sure that the unit is properly installed. An improperly installed unit can vibrate and create excess noise.
  2. Second, keep the unit clean and free of debris. A build-up of dust and dirt can cause the unit to work harder and produce more noise. Make sure that the area around your outdoor unit is clear of debris.  It will ensure that the unit can work efficiently without any restrictions.
  3. Be sure to change the filter regularly. A dirty filter can restrict airflow and cause all sorts of problems for your air conditioner.
  4. Finally, make sure that the evaporator coils are well-maintained. Dirty coils can restrict airflow and cause the unit to work harder, which can lead to increased noise.

While there are a few things that you can do to prolong the life of your air conditioner, eventually it will need to be replaced. When that time comes, be sure to contact a qualified technician for help. They will be able to properly size the unit for your home and install it correctly, ensuring that it runs smoothly and efficiently for many years to come.

If you follow these simple tips, you can prevent your air conditioner from making too much noise and keep it running smoothly for many years to come.
