A noisy air conditioner can be an unwanted distraction. Imagine that you get one installed so you can sleep easily, only to be constantly woken up by an irritating sound. How is a person supposed to sleep through a loud buzzing noise?

Chances are you probably don’t have your own personal maintenance worker around to take care of your air conditioner’s problems for you. There’s no need to worry about that. With a few simple steps, you should be able to find the source of the problem and we’ll give you the solution.

Identify The Noisy Source

To find out what you’ll need to do to fix the issue, you will first need to identify what the noise sounds like and figure out where it is coming from. Take a look at the following problems and see if you can identify the source that is causing your air conditioner to be so noisy.

A noisy air conditioner is a sign that something isn’t working right. If you don’t identify the problem and find a solution something could go wrong, leading to a breakdown.

My Air Conditioner Is Always Running

If it seems like your air conditioner is always running (or continuously cycling itself on and off), there are a few reasons why this could be happening. 

  • Dirty coils
  • Clogged air filters
  • Faulty controls
  • Leaking refrigerant
  • Frozen evaporator coil
  • Holes in ducks

This is not something you should ignore. If your air conditioner is constantly running then it will make your power bill extremely high. You don’t want to pay for this problem later on. Constant running also puts extra wear and tear damage on your parts. This will lead it to break down a lot sooner. Call an HVAC professional for assistance.

My Air Conditioner Has Been Very Loud Since Day 1

If your air conditioner has been very loud since the first day, then there are two very specific reasons this could be. Either it’s a cheap unit that doesn’t have noise reduction technology or it’s way too big for the space you put it in. Try moving your air conditioner to a larger room, or create a buffer between the unit and a room you need to keep silent. 

I Think My Air Conditioner Is Haunted

Does your device make strange whistling sounds every once in a while that startles you? Don’t worry, it’s nothing to call an exorcist about. This is most likely caused by an issue with airflow and air pressure. It may be from one of the following:

  • Poor ventilation design
  • Clogged filters
  • Leaking ducts
  • The motor speed of the fan

Once you have discovered what the cause of that haunting sound is, all it takes is a quick repair or adjustment to have your device sounding normal again. 

Other Reasons Your A/C Might Be Noisy

Is your air conditioner making a rattling or shaking sound? Make sure you identify whether the sound is coming from the unit or the vent. If it’s the unit it may be caused by a worn bearing in the fan’s motor or one of the fan blades might be damaged. Always consult a professional for help if this is the case. 

If your air conditioner is squeaking or squealing, it is a sign that it’s time to be serviced. There are various reasons this could be happening, but two of the most common ones are a failing blower belt or bearings that need oiling. It’s a good time to get it looked at.

We hope this helped you identify the issue with your air conditioner. Never ignore a noisy air conditioner, or you could be left without a working one.
