I have a window ac unit. There is a central heat duct under the
window. About once every 10 min. I can hear a tick coming from the
window. I haven't pinpointed the exact place yet, but I suspect the
plastic on the ac cover is expanding/contracting and making the tick
I use a space heater in the room where the ac is located so the
central heat does not cycle on as frequently as the ticking occurs.
Anyone know what is going on or how to STOP THE DAMN TICKING?
