The FFTA123WA2 uses a remote with a temperature sensor so the unit can cool based on where you are sitting. If the room feels off, the remote may be in direct sun or too far away, which skews the reading.
For through-the-wall units, the outdoor grille and sleeve condition are critical. Leaves, nests or a crushed grille can starve the condenser of air and make the unit run hot, so a technician checks the outside before diagnosing the refrigerant side.
