Why is Your Window Ac Making So Much Noise?
There are a few reasons your window air conditioner might be making more noise than usual. It could be that the unit is getting old and needs to be replaced, or something could be blocking or limiting the airflow. In either case, it’s important to identify the source of the problem so you can take steps to fix it.
If your window air conditioner is making a lot of noise, you should first check the filters. Over time, dust and dirt can build up on the filters, restricting airflow and causing the unit to work harder (and make more noise) to cool your home. Clean or replace the filters as needed to see if that solves the problem.
12 Smart Ways on How to Quiet a Noisy Window Air Conditioner
1. Check the Air Filter
One of the first things you should do if your window air conditioner is making a lot of noise is to check the air filter. If the air filter is dirty, it can restrict airflow and cause the unit to work harder, leading to increased noise. To clean the air filter, remove it from the unit and wash it with soap and water. If your air filter is excessively dirty, you may need to replace it.
2. Inspect the Fan Blades
If the fan blades on your window air conditioner are bent or damaged, this can cause them to hit other parts of the unit, resulting in increased noise. To fix this problem, straighten or replace the fan blades. If your air conditioner is still noisy after inspecting the fan blades, move on to the next step. Ensure to turn off the power to the unit before inspecting or replacing the fan blades.
3. Clean the Condenser Coils
The condenser coils on your air conditioner help dissipate heat; if they are dirty, this can cause the unit to work harder and produce more noise. To clean the coils, remove the unit’s front panel and use a soft brush or vacuum attachment to remove any dirt or debris. You can also clean the coils with a commercial coil cleaning solution, available at most hardware stores.
4. Check the Blower Wheel
The blower wheel is responsible for moving air through the unit; if it is damaged or dirty, it can cause your window air conditioner to make a lot of noise. To check the blower wheel, turn off the power to the unit and remove the front panel. Locate the blower wheel and inspect it for damage. If it is damaged, you will need to replace it. If it is not damaged, clean it with a brush or cloth.
5. Inspect the Evaporator Coils
The evaporator coils are responsible for absorbing heat from the air; if they are dirty, it can cause your window air conditioner to work harder and make more noise. To clean the coils, turn off the unit and remove the front panel. Next, use a soft brush attachment on your vacuum to gently remove any dirt or debris that has built up on the coils. If the coils are severely dirty, you may need to use a foaming coil cleaner.
6. Lubricate the Fan
If your window air conditioner has a fan, it may make noise because it is not properly lubricated. To lubricate the fan, add a few oil drops to the bearings. Once you have done this, run the fan for a few minutes to distribute the oil evenly. If the noise persists, you may need to replace the fan. If the fan is not the problem, move on to the next step.
7. Check for Loose Parts
If there are any loose parts on your window air conditioner, they may be causing the unit to make noise. To fix this, tighten any loose screws or bolts. You may also need to replace any damaged parts. You may need to call a professional for help if the problem persists. Make sure to turn off the power to the air conditioner before attempting any repairs.
8. Add Sound Dampening Material
If your window air conditioner still makes too much noise, you can add sound-dampening material to the unit. This will help reduce the amount of noise emitted from the unit. You can purchase sound-dampening material from most hardware stores. If the noise is still too loud, you may need to purchase a new window air conditioner. Make sure that the unit is properly installed and that it is the correct size for the room.
9. Consider Replacing the Unit
If your window air conditioner is over ten years old, it may be time to replace it. Newer units are often much quieter than older models. You should also consider replacing the unit if it is not cooling the room properly or if it requires frequent repairs.
When purchasing a new unit, choose one that is the correct size for the room. A unit that is too small or too large will not operate efficiently and will be more likely to break down. You should also look for a unit with a good warranty. This will protect you if the unit breaks down within a few years of purchase.
10. Clean the Air Filter
If your air conditioner’s air filter is dirty, it can restrict airflow and cause the unit to make noise. To clean the filter, simply remove it from the unit and rinse it with water. Let the filter dry completely before putting it back in place. If your air conditioner’s air filter is very dirty, you may need to replace it. Also, look for any debris that may be blocking the air filter. If you find any, remove it and clean the area.
11. Place on a Rubber Mat:
If your window air conditioner is making vibration noises, you may be able to reduce these by placing the unit on a rubber mat. Rubber mats help absorb vibrations and can significantly reduce the amount of noise emitted from the unit. However, if your window air conditioner is still noisy after placing it on a rubber mat, you may need to investigate other potential causes of the noise further.
12. Inspect the Unit’s Fans:
If your window air conditioner is making a rattling noise, one potential cause could be that something is caught in the unit’s fan blades. First, inspect the fan blades to see if anything is caught in them. If there is, carefully remove the object and dispose of it properly. Once the fan blades are clear, the rattling noise should stop.
