A/C built-in thermostat question - A/C not cycling often

More than likely, the problem is the bedroom unit is somewhat confined. The thermostat will simply start and stop the compressor based on what it is sensing.

You can add a fan or two to help get air out of the bedroom. Mount one up high blowing into the bedroom and set one on the floor to blow air out of the bedroom. This will help the circulation a bunch.
