Why Is My Air Conditioner Making a High-Pitched Noise?
Some noises coming from your air conditioner make sense. You’ll hear a low hum when the motor runs or a click when the unit shuts on and off. However, air conditioners can make more concerning sounds, like hissing or shrieking.
A high-pitched noise coming from your AC is likely attributed to reduced airflow. An easy DIY fix often does the trick, but if they don’t resolve the issue, you need professional AC repair.
What To Do Before Calling a Professional
Fortunately, there are common air conditioner airflow problems that you can fix yourself!
- Replace dirty air filters: Dirty air filters can block the conditioned air from moving through your house. They can also cause the air quality in your home to drop since your air conditioner is pushing dust and allergens around.
- Clear blocked air return vents: Air conditioner return vents should be open and accessible. If they’re blocked by furniture, the airflow in your home is restricted. This causes your air conditioner to work harder because less airflow goes back into the system.
- Open dampers: Dampers are the movable plates in your ductwork that direct air into certain parts of the house. If some dampers are closed, the air conditioner must work harder to cool your entire home.
Airflow Issues That Need Professional Repair
If none of those fixes resolve the high-pitched sound, it’s time to call an HVAC professional for help. Bigger issues that can cause this noise include:
A major sign of leaking refrigerant is a hissing sound from your air conditioning system. Refrigerant leaks mean your air conditioning system is not working efficiently. You’ll have higher energy bills, and your home may not reach your desired temperature.
A Malfunctioning Blower
If your air conditioner blower stops working, you may hear a high-pitched shriek. There are many reasons your air conditioner’s blower could stop working. To ensure the problem is solved quickly and correctly, you should let a professional technician handle the project.
