compressor
 

When my ac start..I hear a click.. loud noise by the compressor...I think may be the fan motor but not sure..any sugestions..thankx

Are you having a problem with the system or just wondering what the clicking noise is?
The click could be the contactor engaging.

The sistem its workin fine just concer about that clikin noise

the unit does have moving parts. your most likely hearing the contactor engage and the clicking sound is typical.
