Possible Reasons Why Your Air Conditioner Sounds Like a Jet Engine

Air conditioners are a great way to keep your home cool and comfortable during the hot summer months. However, some air conditioners can be quite noisy as a result you would encounter with the air conditioner sounds like a jet engine problem.

This is because air conditioners use a compressor to force the air through the cooling coils. The compressor works like a jet engine, creating a loud humming sound.

The sound can be extremely annoying for you and your family especially when you are trying to relax or sleep, and it may be difficult to ignore. There are some common causes of this noise that you can be aware of. 

  • One of the most common causes of air conditioner noise like a jet engine is the blower wheel. If the blower wheel is unbalanced or damaged, it can cause vibrations and make a loud noise. 
  • Another common cause is a build-up of dirt and debris in the unit, which can prevent air from flowing freely and cause rattling noises.
  • Lastly, if the fan is loose or not properly secured, it can cause a loud, whirring sound. It is important to have your air conditioner serviced regularly to avoid any of these issues.

Thankfully, there are ways to reduce the sound of an air conditioner. Let’s look at the steps to diagnose and fix an air conditioner that sounds like a jet engine.

Solved: Air Conditioner Sounds Like a Jet Engine

If your air conditioner sounds like a jet engine, it can be incredibly annoying. Fortunately, there are a few steps you can take to diagnose and fix the problem. 

Debris accumulation

First, check to make sure that all the filters, grills, and vents are free from dust and debris. If they are blocked, the noise may be coming from an airflow issue.

Fan motor

 If the AC is free from vents and grills, then it may be time to check the fan motor. Make sure the fan motor is securely attached to the unit and that all the wiring is secure. If the fan motor is loose, it may be causing the jet engine noise. 

Refrigerant leak

If an AC sounds like a jet engine, it’s probably because there is a refrigerant leak. A refrigerant leak can often be the culprit for an AC that sounds like a jet engine. The noise is caused by the compressor and fan blades spinning too fast and hitting the housing of the unit. If this occurs, you will need to have your appliance serviced as soon as possible.

Broken or fatigued AC Belt

If you’ve ever been in a room with an air conditioner and heard that loud, jet engine-like noise, it could be because the AC belt is broken or too loose. The AC belt is the part of the system that connects to the compressor and fan. The belt is responsible for driving the compressor, and it can get worn out over time. If the belt is broken or too loose, it will make a loud noise when running. The sound is similar to that of a jet engine taking off.

Loose components

If your air conditioner sounds like jet engine, check for any loose parts in the unit, such as fan blades or loose screws, and tighten them if necessary. Additionally, you can also try lubricating any moving parts, such as the motor, to reduce friction and noise.

Contact customer care

If it appears to be in good condition, then it’s time to call a professional for a proper diagnosis. A professional can determine the source of the noise and provide a solution to get your air conditioner running smoothly and quietly. Finally, if the problem persists, contact a local HVAC technician to inspect and repair the unit. Taking these simple steps can help make sure your air conditioner runs smoothly and quietly.

Why does my AC sound like an air compressor?

Excessive Compressor Pressure If you notice that the hissing noise has turned into a screeching noise after some time, then you have a compressor problem. Your outdoor AC unit may have developed high pressure. This problem requires immediate attention, so turn off your air conditioner and call a professional.

Why is my air conditioner suddenly so loud?

Much louder noises and new modified noises may indicate a major problem with your air conditioner, such as a malfunctioning compressor, poor blower motor bearings, or mechanical damage.

What does an overcharged air conditioner sound like?

An overcharged air conditioner frequently makes buzzing, rattling, or knocking noises. The sound is frequently caused by the added strain experienced by the compressor. The noise is likely to be heard when an excessive volume of refrigerant travels through a tiny nozzle in the system.

How long will a noisy air conditioner compressor last?

However, you can typically expect your AC compressor to last 8-10 years, which for many drivers equates to the life of the vehicle.

What is the most common cause of air conditioner failure?

The compressor and fan controls can wear out, especially if the air conditioner cycles on and off repeatedly, as is frequent with big systems. Electrical connections and contacts should be checked during a professional service call because corrosion of wire and terminals is also an issue in many systems.


We cannot deny the fact that an air conditioner sounds like a jet engine is a pretty annoying problem. While this noise can be startling and concerning, it is usually not a sign of a major problem.

You can go through the above fixes and try diagnosing the problem by yourself. In case of things seems out of your reach, make sure to have a talk with customer support for further help.
