Sounds like you have an air handler. If that's the case, depending on if the air is flowing up or down which is called an upflow or downflow piece of equipment. The arrow would go towards the blower motor.
To clean the coil: shut the main power off and take the panels off. Use a dry brush and stroke in line with the fins. Spray 409 and hose it down with water. Make sure unit is dry before you turn the power back on so you don't short anything out. You would normally be charged $275.00 for that.

If the filter is in the return air duct, as most of them are, the arrow should point into the duct. That is the direction of air flow.
