Air Conditioner Sounds Like a Jet Engine? Quiet It Now!
Is your AC very loud? Do you feel your air conditioner sounds like a jet engine?
Dont worry! Although the sound gives you a minor heart attack but with patient and genuine effort, you can easily fix the issue.
However, an air conditioner that sounds like a jet engine could be caused by various issues, such as a malfunctioning fan, a clogged filter, or even loose components.
Let’s explore the cause of this weird sound and try to figure out a workable solution.
Causes of Air Conditioner Jet Engine Sounds:
The “jet engine” sound usually indicates a problem with the air conditioner’s fan motor or blower. Generally, this component is responsible for circulating cool air throughout your home. Here are some of the most likely culprits:
1. Fan Motor Problems:
The fan motor’s bearings, which allow the shaft to rotate smoothly, can wear down after a year of use. This wear can cause friction, leading to a loud grinding noise. Therefore, if the fan blades are loose or broken, they can vibrate and create a rattling or roaring sound. In fact, when the motor is overloaded, it may struggle to turn, resulting in a loud humming or whining noise. This can occur due to a clogged air filter, dirty condenser coils, or a malfunctioning thermostat.
2. Blower Problems:
The blower wheel pushes air through the ductwork. If it is worn or damaged, it causes a rattling or screeching noise. On the other hand, if the blower house becomes loose, it can vibrate and create a loud humming or rattling noise. Besides, when anything blocking the airflow through the blower, like debris, dust, or a clogged air filter, can cause the blower to work harder and generate more noise.
3. Other Potential Causes:
A refrigerant leak can cause the compressor to work harder and create a loud, rattling noise. In addition, other components, such as the compressor, condenser fan motor, or the air handler itself, can become loose or damaged, leading to excessive noise.
How to Fix Air Conditioner Jet Engine Noise
Depending on the cause of the noise, there are several potential fixes you can explore:
Step 1: Start by replacing the air filters. Clean or new filters can significantly reduce noise levels by allowing proper airflow.
You can replace the air filter every 1-3 months, depending on usage and the type of filter. If your air filter is reusable, then clean it with water and mild soap every week for better performance.
Step 2: Next, clean the condenser and evaporator coils. Dirty coils often restrict airflow and cause the system to work harder, increasing noise. Regularly cleaning the coils can help maintain optimal performance.
Use a garden hose with a nozzle to spray water through the coils, removing dirt and debris. Avoid using a pressure washer, as it can damage the fins.
Step 3: Check for any loose screws, bolts, or brackets on the air conditioner unit and tighten them securely. Now, if the noise is due to loose parts or components, tightening them may solve the problem. However, exercise caution and consider seeking professional assistance if you’re unsure about the process.
Step 4: Lubricating moving parts, such as the blower motor or fan bearings, can help reduce friction and minimize noise. Depending on usage, lubricate the bearings every 1-2 years.
If your air conditioner has accessible fan motor bearings, apply a few drops of oil to each bearing. Consult your owner’s manual for specific instructions.
Step 5: Lastly, if you’ve identified a worn or damaged part, such as a fan blade, blower wheel, or motor bearing, replace it with a new one. A professional technician may be necessary to repair or replace it.
Safety Considerations
- Always disconnect the power to the air conditioner before working on it.
- Use a ladder or step stool safely and securely when working on the unit.
- Wear gloves and eye protection when handling cleaning solutions or refrigerants.

How to Diagnose Your AC’s Loud Noise
To find out why your AC is loud, you can check some things. Here’s what you can do:
- Listen to your AC. Where is the sound coming from?
- Look for dirt or sticks in the outside unit.
- Is the fan inside clean and moving right?
- Feel the AC. Is it shaking a lot?
Write down what you notice. It will help later.
Is It Safe to Run an AC When It Makes Jet-Like Sounds?
Running an air conditioner that sounds like a jet engine may not be immediately dangerous, but it’s generally not recommended for an extended period. Excessive noise can indicate a larger underlying issue that, if left unaddressed, could lead to further damage or system failure.
If the noise is accompanied by other symptoms, such as decreased cooling efficiency or odd smells, it’s best to turn off the unit and have it inspected by a professional technician. Continuing to operate a malfunctioning air conditioner can potentially cause more damage and lead to higher repair costs in the long run.
Final Words
Lastly, an air conditioner that sounds like a jet engine is a sign of a potential problem that needs attention. If you can’t find a solution, don’t wait—immediately contact a professional technician. Because your home should be a peaceful place. Keep your AC working well so it’s never as loud as a jet plane.
Take care!
