moan/groan when a/c is first turned on...
 

Lately when I first turn on the a/c I get a moan or groaning noise...only lasts for a minute or so and then goes back off again.

If a/c is not on, I do not hear this noise...only when a/c is turned on. :confused:

any ideas?

Thanks!

no one?

any ideas at all?

ac compressor? blower motor?
