Your air conditioner makes loud noises when it is turned on
You may hear loud noises when your air conditioning unit is first turned on. Listen carefully to these sounds, as there are many types of noise thatrefrigeration unitscan do. Each sound points to a specific problem that needs to be investigated and resolved. This is not a problem you have to solve yourself. It is much better to contact an HVAC technician for help.
Different noises that air conditioners can make
Read on to learn more about strange air conditioning sounds.
1. Sounds of slamming doors and blows of the air conditioner
Your air conditioner has an external fan motor that pushes air into your home. If the fan motor is damaged, it will probably make one or two strange noises during operation. Pieces can come loose and start hitting the cage. Thermal expansion, moving debris, and even shock movements can also be to blame.

2. A persistent click on the AC unit
Clicking noises from the air conditioner are a sign of electrical problems. You can try to turn on the air conditioning, but nothing happens. This is also a problem that should only be handled by professional HVAC technicians. They will take a look at the thermostat, compressor and condenser.
3. Your air conditioner is screeching
If you hear a metal-on-metal noise, it could be because the blower motor bearings are broken or worn. This isn't exactly an emergency; however, it's still a good idea to take action before the problem worsens. Have an HVAC professional take care of this before you start using the air conditioner again.
4. The cooling system is pulsating
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.

5. Your air conditioner is humming
Buzzing noises from the cooling system indicate a mechanical problem within the air conditioner. This sound can occur both indoors and outdoors. Some of the most common causes of hum include bad blades, broken belts, fan motors, and bad bearings. Turn off the air conditioner immediately and contact a local HVAC company for repairs.
6. The air conditioner is humming or buzzing
If the outdoor air conditioner begins to make an audible hum, check for trapped debris. Leaves, flowers, and twigs can enter through various holes. Remove them immediately. The hum can also be an indication of a worn out fan.
7. The air conditioner is noisy
Noise is often the result of air conditioner parts loosening due to vibration. Check the screws and bolts around your air conditioner. These may need to be reinforced. It is a good idea to additionally change the AC air filter and clean the coils in the unit. Better yet, contact an HVAC company to schedule professional air conditioning maintenance.

Common Ways HVAC Contractors Deal With Air Conditioning Noise
1. Straighten and clean the fins on the unit coil.
To improve the efficiency and overall performance of your air conditioner coil fins, be sure to keep them clean. Contact an HVAC company to schedule annual tune-up services for your air conditioner. During these visits, your technician will straighten the coil fins with a fin comb; You can also use a vacuum with a brush to clean all the dirt and other debris.

2. Tighten all loose screws
Considering the number of moving parts your air conditioner has, it is normal for these units to vibrate slightly during operation. However, over time, this vibration can cause the bolts to loosen. It could even get to the point where you hear an audible hum every time the unit is turned on. Regular HVAC maintenance will give technicians a chance to tighten loose screws.
3. Debris must be removed from the blades.
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. This is a quick cleanup that homeowners can do themselves. However, for a deeper clean to increase efficiency and comfort, call a reputable HVAC contractor.
4. Bent blades must be straightened
After removing all the dirt and debris, take a minute to inspect the blades for any problems. Irregular blades can be bent back to their correct shape. Contact an HVAC company if you see bent blades. They can deal with this problem carefully to prevent the problems from getting worse. They will carefully inspect each blade and put them back in order.

5. The motor can be lubricated
Squealing noises can indicate that the engine needs lubrication. Lubricating this component is something your technician will do during adjustments, that way there will never be any squealing noises. They will use the correct oil for the job so that any existing sounds are eliminated. They can also add oil to the ports at the base of the air conditioning unit's fan motor.
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.

5. Take a look at the indoor air handler
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.
How to avoid strange noises from the air conditioner
1. Place a noise limiting barrier
Loud noises from the air conditioner can make it difficult to hear your own thoughts. Too much sound during AC operation can make it difficult to sleep. You can install a noise limiting barrier to reduce excess sound. A noise reduction fence or sound blanket is perfect for this. However, ask your HVAC contractor before completing this.
2. Perform routine HVAC maintenance
Schedule annual HVAC maintenance. Technicians can detect problems while they are still minor. They can take immediate action to prevent things from getting out of hand. They can also completely clean the air conditioner so you don't have to. These measures will limit the likelihood of extraneous sounds developing.
