To properly shift a compact crankset, you should anticipate the gear change by easing off the pedals slightly to reduce tension on the chain. Then, use the shifters to move the chain onto the desired chainring, making sure to shift smoothly and not force the gears. It's important to continue pedaling lightly as you shift to help the chain move smoothly between chainrings. Finally, once the chain has successfully shifted, you can resume pedaling with your desired gear ratio. **

There could be several reasons why a portable air conditioner is not cooling properly. It could be due to a dirty air filter, which restricts airflow and reduces the unit's cooling capacity. Another possible reason is that the unit is too small for the size of the room, or the room may not be properly sealed, causing cool air to escape. Additionally, the unit may be low on refrigerant, which can affect its cooling performance. It's important to troubleshoot these potential issues to ensure the portable air conditioner is functioning properly. **
