10 Reasons Of Why Is My Window Air Conditioner So Loud

Window Air conditioners are incredibly easy to use and reliable. However, they do face issues at times. One of the most popular issues while using a window air conditioner is how noisy it can be. There are many reasons why my window air conditioner is so loud. 

Here are 10 reasons why is my window air conditioner so loud- uncleaned filters, maintenance, dirt, lubrication, damaged fan, dismounted, front grill, motor, leaves or other debris.

Here are the detailed versions of those ten reasons: 

1) The air conditioner filters haven’t been cleaned properly.

2) It needs annual maintenance.

3) There’s dirt on the fan blades.

4) As a precaution, I should examine my window air conditioners if they suddenly start producing a lot of noise. It is possible for leaves, animals, and other garbage to easily enter the unit since it is hung outdoors. 

To see what’s going on inside a window air conditioner, I disconnect it, remove the grill, and use a flashlight to see in.

5) When there’s a lack of lubrication, the fan motor starts making loud noises.

6) The fan blades got damaged.

7) Window air conditioners sit on the window frame if the window air conditioner is not appropriately mounted. 

8) There’s something wrong with the motor of the window air conditioner.

9) The front grill of the window air conditioner is loose.

10) The fan blades somehow got bent.

These are the possible reasons behind my window air conditioner making noises. However, there might be some other problems as well.

Ways To Get Rid Of The Noise Of Window Air Conditioners

The reasons given above are why Window air conditioners make noise. This noise can be very annoying. So, here are a few ways to get rid of the noise of window air conditioners:

1) Checking the Installation: even though almost everyone can install a window air conditioner, getting it right can be very tricky. First, ensure that the unit is still installed adequately to the window frame. A quick and easy test is to push on different frame parts and check if it affects the noise.

2) Checking the panel: By checking the panel, we can ensure that the screws on it aren’t loose. Loose screws in the panel can often cause the noise produced by window air conditioners. If the screws are loose, we can get them fixed by a professional technician. 

3) Checking the fan blades: Sometimes, unknown debris gets stuck in our window air conditioners. The unknown debris often bends the fan blades, which leads to the noise made by the window air conditioner. 

By checking the fan blades, we can make sure they are okay. If they are bent, we can quickly call a professional technician. 

4) Checking the motor: Sometimes the reason behind noise made by a window air conditioner is because there’s something wrong with the motor. A professional technician can easily fix window air conditioner motors.

5) Check the coil fins: The back of window air conditioners reside in the cooling coils. By taking the back off of the air conditioner, giving the coils a light dusting and vacuum, it can be ensured that the coil fins are okay. 

If they seem bent, gently straightening them by running a comb down them is an excellent way to fix them.

6) Repositioning: If anything is loose or clashing with another part, gently removing these apart or stopping the noise by adding a type of cushion can fix the noise.

7) Reinforcing: If it’s the window frame that’s causing the noise, then tightening the unit’s screws can fix the noise problem—adding foam weatherstripping around the frame cushions the vibrations.

By using these tactics, you can easily prevent noise made by your window air conditioner. There are also many other ways to prevent noise made by your window air conditioner.

How Loud Are Window Air Conditioners?

Window air conditioners are a bit louder than standard air conditioners. But the noise doesn’t come from them. It comes from the outside. There’s no way to get rid of the noise when the window air conditioner is on because it needs to access outside air to work.

Most window air conditioners are rated in the 50-to 80 dB range. 50 to 80dB is not that loud. 

Measuring Window Air Conditioner Sound Level

Measuring window air conditioner sound level is tricky, but it’s also essential. Here’s how you can measure your window air conditioner sound level without a hassle:

Air conditioner sound levels are always measured in decibels (dB). The lower the decibel rating is, the quieter the air conditioner will be.

The quietest AC’s fall into the 50–60 dB range. So, here are some familiar sounds that fall into the 50-60 decibel range:

The sound of rainfall- 50 decibels

The sound of coffee percolating- 55 decibels

The sound of an electric toothbrush- 50–60 decibels

The sound of a normal conversation- 60 decibels

The sound of a sewing machine running- 60 decibels

How To Sound Proof A Window Air Conditioner From The Noise Made Outside?

The main disadvantage of using a window air conditioner is the amount of outside noise. There’s no way to get rid of the noise when the window air conditioner is on – as it needs to access outside air to work.

The solution to this problem is to cut some metal or wood to snap-fit around the back of your window air conditioner along with a vertical funnel that has an opening at the top. This lets the window air conditioner ‘breathe’ while ensuring the noise remains outside.

However, you would have to seek help from a professional to cut this and to get this done. But if you are desperate, then take the measurements of your unit and head to a local to buy the products you need. After that, you can and try to make it by yourself. 

This idea works well. You can enjoy the relaxed and comfy atmosphere without outside noise interference by taking this initiative. 

Ways To Keep Your Window Air Conditioner Running 

Window Air conditioners have a long lifespan. However, window air conditioners slowly lose their efficiency as they start to age. So the best ways to keep your air conditioner running correctly are given below:

1) Keeping the filters of your window air conditioner clean. During summer, about every month, take the filter out and give it a good soak. After 5 minutes have passed, please give it a good wipe down, then leave it out to dry before placing it back inside. 

If the filter has become way too dirty, buying a new one is an excellent option. If you also want to protect against allergens and other toxins, look for HEPA-certified filters.

2) Take proper care of your coils. Your window air conditioner contains both evaporator coils (resides in the room) and condenser coils (resides outside the room). Both of these can get clogged up with dust and dirt. 

However, it takes about 5 minutes to wipe it down. To clean your window air conditioner this way, you need to take the  Air conditioner off the frame and then the front and back panels. Afterwards, spray some soapy water or glass cleaner on the coils, wait a few minutes, and gently wipe them down. 

You can only wipe downwards in the direction of the fins. Even though this can be a pain in your butt, you only need to do it once a year at the beginning of the season.

3) Straighten The Fins of your window air conditioner. Even though you’re busy with the above, make sure to also gently straighten any fins which are misplaced. The best to fix this is by gently running a comb downwards along with them. 

4) Wipe down The Fan Blades for your window air conditioner.  Make sure also to wipe down the fan blades to get rid of any dust and debris on them.

5) Keeping an eye on your drain pan is very important. If your window air conditioner’s drain pan gets too full, then the condensation can get stuck inside the air conditioner. All you need to do is drain it down your sink and give it a quick wipe down whenever needed.

6) When you are not using your window air conditioner, it’s tempting to chuck your window air conditioner into any old storage spot! First, however, they need to be taken care of. So take them down, place them inside a box, and keep them in a dry, excellent space. 

Then, allow your window air conditioner an entire winter’s hibernation before you wake it back up. 

By taking these steps, you can elongate the life of your window air conditioner. These steps can make a vast difference. 

Are Window Air Conditioners Energy-Efficient?

Even the most energy-efficient window air conditioner uses more energy than a regular central air conditioner. But it will cost you a lot less than a central air conditioner if you only choose to cool one or two rooms. By using this technique, you are only paying for the comfort of the rooms you use.

Energy efficiency decreases very dramatically if you put window air conditioner units in every room of the house.

A central air conditioning unit can cool down an entire home or at least a single zone because of its design. So naturally, this requires more electricity than a window unit that is only cooling a single room.
