The installer probably left a piece of cardboard, plastic, or styrofoam in the unit from packing that is being hit by the condensor fan blades.

Pull it out of the wall, and look for any obstructions of that nature.

Also look for any loose wires or parts that could be hitting it.

It also is not unheard of to have a fan motor with bad bearings from the factory.

You might be able to find a sound insulating blanket that wraps around compressor. Check with a Carrier or York dealer. Most brands use the same compressors so you might be able to score one.

No. This can be caused my a dirty squirrel cage on the blower motor which is found in your air handler in the attic. Probably needs to be pulled out and cleaned. This noise is caused by the blower wheel out of blanace.

Loud bang, sounds like the motors going to drop out when the compresser kicks on,17 years old, relpace/repair


The actual internal motor in the compressor dome is mounted on springs. Over time these get weak and hence the loud bang noise when the motor hits the sidewall of the compressor housing. It is not too serious and will probably work for ages. Just anoying. Leave it until it really packs up.

Sherp air conditioner AFR120DX running loud. Drain is open and there is no water buildup. The fan shaft seems to be straight and smooth. Any suggestions for trouble shooting?


It sounds like it could be low on refrigerant. without refrigerant it will be loud and it will not sweat. However it could be restriction in the refrigerant lines that will not allow the refrigerant to move. This will have the same symptoms. Both solutions sound like a job for a licensed technician.
