My panasonic air conditioner does not turn off when cooling
At what temperature is the thermostat?
The temperature should never be lower than 70?F (21?C) for the unit to operate properly. If your temperature setting is above 70?F, then your unit might have a problem with the temperature sensor that controls the "on/off" cycle on your unit. For that you will need a professional certified HVAC tech to inspect it.
Most people think that lowering the temperature to the minimum will cool the room faster, but that is not the case. Since HVAC units move the air at a specific rate, it can only transfer the temperature, thus cooling/heating the air, within those parameters. That's what the calculation for the BTU is for. Normally cooling/heating the room to the desired temperature should take about 1 hour, but some new inverter units can do it in only 30 minutes or so. Lowering the temperature constantly or even keeping it at the lowest setting may cause premature failure of the unit.
