Why is my Mitsubishi Heavy Industries SRK20ZS-S not cooling or heating properly?

If your Mitsubishi Heavy Industries Air Conditioner isn't cooling or heating well, make sure the thermostat is set to a suitable temperature. Also, check if the air filter is clean and not clogged. Finally, ensure that all doors and windows are closed.
