Hi,
I have a month old Carrier 24AHA4, which was professionally installed. It worked great the first 3 weeks, but then it occasionally starts to vibrate. When it happens, pattern is normal initial operation for 20-30 minutes, then loud vibration, and after a while reverts back to normal operation. It happens a few times a day (can hear it in the whole house due to the vibration), and can be reset by turning the unit off and on.
Has anyone seen this before? The AC contractor came out twice for this, but of course it doesn't happen when he is here.
