  • I don’t think I’ve seen variable speed fans and compressors mentioned. If the thermostat can learn the heat loss/gain it can let the compressor/fan spool down to use less electricity occasionally. Also not all motors are at peak efficiency while they’re at peak speed, so slowing it down can reduce electricity usage more than it reduces heat transfer.

    Eta: variable speed can also prevent cycling where the air conditioner runs full blast for 5 minutes an hour because it’s oversized or not hot enough outside.
