Why does my AC make a loud noise when I turn it on?
If you only hear the noise when your unit turns on, the compressor motor is a likely culprit. The slamming noise is likely the damper closing after the AC shuts off. You may also be hearing loud creaking noises from the ducts expanding and contracting from pressure and temperature changes if you have sheet metal ducts.
Why is my central air conditioner making a loud noise?
If your air conditioner is making a shrieking noise, this is an indicator of an issue with the fan motor. This sound may also be caused by a broken motor in the compressor of the condenser system. If you hear a loud AC sound, immediately deactivate your air conditioner and call a professional HVAC contractor.

Should my AC unit be loud?
When functioning efficiently, your air conditioning system should be relatively silent, aside from a slight humming when the system kicks on and off. Keep in mind, the unit outdoors will be loud when it’s running, but it shouldn’t produce any strange or shrill noises.
How loud are central air units?
Most residential AC units are around 72-82 decibels when they’re running. Air conditioners can be an issue for homeowners and neighbours, so there are noise level restrictions, although these levels are contingent upon location.

Why is my compressor loud?
Your AC compressor is the part that’s responsible for circulating refrigerant (the liquid/gas that cools your home’s air). Due to normal wear and tear, parts inside the compressor can become loose and create a loud banging sound as they rattle around inside the compressor’s outer casing.
What can I do if my neighbors air conditioner is loud?
You can install a special sound-dampening blanket on the inside of the air conditioning unit to muffle and contain the noise. The blanket should be carefully installed around the compressor, taking care not to block or come in contact with moving parts, such as the fan.
