Has your air conditioner noise been bothering you or your neighbours lately?

Then it’s time to look into the possible reasons why it’s making those strange sounds. Remember the noise factor determines your comfort level and running costs, too. So, if you want to avoid huge power bills and conflicts with people around you, listen to your AC carefully! 

Peace and quiet…that’s all you wish for after a hard day at work. And when your air conditioner disrupts all that calm, you probably think of how to get rid of it faster. Actually, a loud AC not only that it ruins your day but it can also show you signs of a bad operating system. While it is working hard to keep you comfortable, in reality, it may be wasting both your money and energy.

In order to fix all these issues, here are some tips and tricks we’ve prepared for you:

1. Read the technical specifications before buying the AC unit and choose a newer model for its improved technology

If you’re looking to buy an air conditioner, you may want to learn about the unit’s noise levels first. You normally find them in the product specifications, measured in decibels (dB). Basically, there are two numbers: one that refers to the noise that the unit makes inside the home, and the other that refers to exterior noise.

Generally speaking, keep in mind that older air conditioners can be noisier than newer ones. Plus, you should also add a trusted brand in your buying decision. For this reason, we recommend you to choose AC units having interior noise levels no louder than 35 dB. As for exterior noise, the rule of thumb is up to 5 dB above the area normal ambient noise.

2. Carefully consider possible locations, then install the air conditioner properly

Next, you should definitely be very careful with the unit placement. Usually, a correct air conditioner installation will ensure a long-lasting and efficient operation for many years to come.

For added peace of mind, asking an experienced technician’s advice about the installation is the best way to do it.

3. Pay attention to unusual sounds

Another important thing is to listen to what your conditioner has to “tell” you. Every sound means a different symptom, hence, a sick system. In fact, you can imagine some kind of legend with the type of sounds your unit may be making:

Squeaking: this typically warns you that your unit needs cleaning or some extra lubrication.

Humming: it may be a build-up of dust and debris inside the unit. If it’s getting very intense, this may indicate that your starting capacitor is failing, which is a more serious problem.

Grinding: usually, this translates into “something is about to go wrong”. For example, it can be an essential bearing failing, or a dual shaft motor breaking down. We highly advise you not to ignore this sign!

Rattling: this means your fan rotor is loose. In this case, you should stop the unit and call a licensed technician for a service check.

Hissing: this may probably be the most concerning sounds of all. In the worst case scenario, the unit may be leaking refrigerant, which puts you and your family in danger. Therefore, it’s essential to call a specialist as soon as possible.

4. Schedule a regular professional maintenance for optimal performance

Last but not least, don’t forget about the regular air conditioner maintenance.  In fact, calling a qualified technician may prevent many of the problems mentioned above from happening.
