Summertime in Southern California means t-shirts, shorts, and endless hours spent at the beach. Nonetheless, it also means it’s time to kick on the beloved air conditioning unit. What happens when you decide to turn on your AC, and it sounds like it’s whistling? Even worse, the AC isn’t working at all!
Let’s face it; summer won’t be much fun if you can’t cool down in your own home. When your AC isn’t working and it’s unbearably hot outside, it’s time to take some action.
Once sweltering, humid weather rolls around, the last thing you want is an air conditioner that begins to make high-pitched noises. If your AC unit is making noise of any kind, we highly recommend that you seek help from a professional AC repair service in San Bernardino like Redlands & Henry Bush Plumbing Heating & Air Conditioning that can diagnose and fix the problem efficiently.
What Causes an AC Unit to Make a High-Pitched Noise?
We know panic happens as soon as your AC unit begins to make noises it didn’t make before. Nonetheless, high-pitched noises coming from an air conditioning unit are caused by several factors that are easy to fix. If your AC unit is making high-pitched noises, it’s likely due to one of the reasons listed below.
Most Common Reasons for AC High Pitched Noises
Closed Vent Dampers
When vent dampers are closed, the air conditioning system will have trouble maintaining optimal airflow. In a normal air conditioner, all vent dampers should be open. Having all vent dampers closed prevents ample airflow throughout your home. Closed vent dampers can equate to a screeching or whistling noise.
Old, Dirty Air Filters
Air conditioning filters should be replaced every month during the summer or anytime you notice the filter is clearly covered with dirt and dust. Dirty air filters are a common reason for your air conditioner not working correctly.
Fan Bearings Worn Out or Improperly Aligned
Older air conditioners have fan belts or bearings. When these belts and bearings have given all they can give, or they aren’t aligned in the right place, it can ultimately result in an annoying screech from your air conditioning unit.
There could be a simple obstruction, such as a small object, in your air conditioning fan. This is an extremely likely reason for your air conditioning suddenly making a loud whistling noise every time you turn it on.
