staying at friends house. has 2 ton central air. condenser unit has rattle/knock sound when running. nice cold air. sometimes, the noise quiets down about 30 sec before outside unit shuts off. i can hear rattle from inside house. friend has a/c service plus plan. called for appt today. 1/2 hr later a/c turned on and it was quiet. what the heck? does it know service call has been scheduled?
