I have a Ruud 14 Seer AC and air handler that was installed in September 2006. My home has baseboard heating. Since the system was installed, the air handler comes on by itself, with the heat on or even with the thermostat set to off. I have had numerous service calls and various parts have been replaced including the thermostat and the circuit board, but this problem keep happening and it results in cold outside air blowing through my house when it is cold outside. The AC compressor never comes on, just the blower turns on. No one has been able to help. Has anyone heard of this and is there any solution? I am almost ready to just rip the whole system out I am getting so frustrated!
