There are a number of issues that can affect play quality. First, ensure that your surface is clean. If you've already wiped it down, check the air holes. Sometimes dust and dirt buildup can block the holes, obstructing airflow. Using a needle, clear each hole, taking care not to widen them.If your air hockey table still doesn't feel right, you may want to take a look at the motor. Excessive dust buildup can severely hamper your fan's performance. Often, a good cleaning is all that's needed.If you've tried all of the above to no avail, try replacing the puck, as these can and do wear out over time.
