My ac unit seems to suddenly be making a knocking noise when the unit is on. It does not make noise when system is off. I thought it might be the fan, but it continues to make noise
While the cooling system runs without the fan.
I can hear the knocking on the Payne AC metal box in my attic which contains the unit. I would appreciate any info you may have. Should I leave the AC off until we can get a service man out. Thanks.
