  If your Tosot Air Conditioner isn't cooling or heating well, several factors could be at play. First, make sure the unit is mounted as level as possible. An unlevel unit can affect performance. Second, check if the set temperature is appropriate and adjust it if needed. A dirty air filter can also restrict airflow, so clean it. Finally, if you've just turned the unit on or off, give it some time to reach the desired temperature.

  If you notice ice or frost on the coils of your Tosot Air Conditioner, there are a couple of things to check. One potential cause is a low inside temperature; if this is the case, switch to FAN mode at HIGH fan speed. Also, a dirty air filter can contribute to this issue, so make sure to clean it.

  If you hear clicking or gurgling sounds when your Tosot Air Conditioner is running, especially just after turning it on or off, this is likely due to the refrigerant flowing inside the unit. This is completely normal.

  If you find water dripping inside your Tosot Air Conditioner, it could be due to the chassis gasket not being evenly compressed and tightened. Ensure that the mounting bolts are tightened evenly to compress the chassis gasket properly.
