Have an HVAC professional take care of this before you start using the air conditioner again.

Low level pulsating sounds can be expected as air flows through these systems. However, pulsating noises from the outdoor unit should not be audible inside your home. If you can hear them, the unit may have broken fan blades or debris, such as twigs, floating inside.

Take a look inside the air conditioner cabinet by opening it. If you find any debris, remove it as soon as possible. Check for foreign objects near the fan blades.

What homeowners can do to deal with loud air conditioning noise

Read on to find out what you can do to deal with strange noises coming from your cooling system.

1. Inspect the air conditioning unit and check the external fan

Before taking any further action, start by checking the condenser fan inside the outdoor unit of your air conditioner. If it still spins, assess how your blades spin. If they seem unbalanced or come into contact with something, it could be that the case has debris on it. Also check the refrigerant pipes and coils. If you're not sure what you're looking for, let a professional handle the job. When in doubt, always let an HVAC technician take care of everything for you.

2. Change the air filter of your air conditioner

This is an important step for all homeowners. Air conditioners cannot function as they should when their filters are clogged and dirty because dirty filters impede airflow. Your air conditioner will constantly struggle and probably hum. Check your air conditioner's air filter at least once a month and replace it as necessary.

3. Clean up a bit around the outdoor air conditioning unit

Things very close to the outdoor air conditioning unit can also cause problems. Debris can get into the cracks. For safety, turn off the air conditioner before opening the cabinet. Remove the top rack and remove any dropped objects. Close well.

4. The run capacitor needs to be checked

After cleaning the unit, turn it back on to see if the fan is spinning. If it doesn't move, try to get it going by using a long stick to move the blade until there is enough momentum. If the blades start to spin, your run capacitor is probably broken.

The problem may not be with the external drive. If you're done with your external inspection, go ahead and take a look at the internal air handler. Check for ice buildup or vented coil fins. With icing, turn power off to thaw and allow to dry completely before turning power back on.

6. Contact an HVAC company

There are many things homeowners can do on their own to resolve and prevent air conditioning noise issues. However, there are things that untrained people simply cannot figure out on their own. If you're still hearing a strange noise after going through this checklist, be sure to schedule a professional air conditioning service.
