It is only natural for us to recognize new things about old products, especially appliances, as we use them more frequently and as they age. Many times, these new recognitions are good – such as finding a setting or feature that we never realized the product had because we barely glimpsed through the manual when we first bought it. But sometimes these new recognitions are not as positive as finding a setting or feature that improves the efficiency and productivity of the appliance. Sometimes, as our appliances continue to age, they also continue to start making sounds we have never heard them make before – and unfortunately, new sounds are usually an indicator of new problems. If you have started to recognize your New AC or the old one making noises you haven’t heard it make in the past, then this post is for you!
Humming Sounds in your New AC
Out of all the new noises your air conditioning unit can make that indicate a problem, humming is most likely the one that is best to hear. This is because a humming noise is usually an indicator of a small issue that you will probably be able to correct on your own. Hearing a humming noise come from your air conditioning unit is usually an indicator that the system is being affected by excessive dirt, dust, and debris. While this could lead to a more serious issue in the future if left unaddressed, the only thing you will probably need to do in order to correct this problem is to remove the top of the unit and gently wipe the interior of the unit down with a cleaning cloth.
Bubbling noises coming from your air conditioning unit are usually an indicator that there is a problem with your refrigerant levels. Many people incorrectly assume that their refrigerant levels need to regularly be re-filled or re-charged, however if you are experiencing an issue with your air conditioner’s refrigerant levels being too low it is more likely an indicator of an issue such as a leak somewhere in the unit. To correct this issue, you should contact an experienced air conditioning technician to come find and correct the leak in your system as soon as possible before the problem becomes any worse.
Buzzing or Clicking Sounds
One of the first indicators of an issue within the electrical system of your air conditioning unit are noises that sound like buzzing or clicking within the unit. A buzzing noise is usually an indicator that there is a loose or frayed wire somewhere within the system that is causing sparks of electricity. These sparks of electricity are the source of the buzzing noise. A clicking noise typically occurs continuously on-and-off and is usually an indicator that there is something preventing the control panel from effectively transmitting electrical signals. When the control panel is not able to effectively transmit an electrical signal, it will continue to try to send the signal until it is successful, which will cause internal switches within the unit to continuously turn on and off and result in a clicking noise continuously running. Any electrical issue with any appliance is a serious concern, but it may have an easy fix available if you contact a professional technician early enough to correct the problem before it causes serious damage.
Squeaking and Squealing Sounds
If your air conditioning unit is making a squeaking or squealing noise, it is most likely an indicator that there is an issue with the fan belt or the motor. An AC unit’s fan belt can be affected by expansion and contraction caused by varying levels in the temperature or levels of humidity throughout different seasons, but issues with a fan belt can usually be repaired by a professional technician. On the other hand, if there is a problem with your AC unit’s motor going bad, you will most likely need to replace the motor in order to correct the issue.
If you hear whistling noises coming from your air conditioning unit while it is running, this is usually an indicator of a problem with the efficiency of the airflow. There are a number of different things that can cause a problem with air flow to occur – ranging from something as simple as a clogged or dirty air filter that needs to be changed to something more serious like leaky ductwork or a broken blower. If cleaning or replacing your current air filter doesn’t stop the whistling noise from occurring, it is best to contact an experienced technician to help you diagnose the source of the noise and correct any underlying issues.
If you hear banging noises coming from your air conditioning unit while it is running, this is usually an indicator that something has come loose and is banging around within the system. In the same way that a whistling noise can be caused by many different issues ranging from small to large, the same applies to banging noises within your AC unit. The source of the banging could be as simple as a small screw or bolt that needs to be tightened, or something more serious such as damage to the fan, compressor, or blower. A professional technician will be able to help you find the source of the banging and correct the issue.
