Why is my McQuay MQS-24036-CFC216A Air Conditioner not cooling or heating properly?

  If your McQuay Air Conditioner isn't cooling or heating properly, several factors could be the cause. First, check for obstructions at the air intake and outlet and remove them. Ensure the temperature is set correctly. Adjust the fan speed and swing settings. Make sure all doors and windows are closed, and block direct sunlight with curtains or blinds. Finally, a dirty air filter can hinder performance, so clean it.
