Your furnace is under warranty. You have to do the check. They always tell you, you will need an annually check. It is a safety concern. Most check should include check the ignition, clean the burner. Check leak, check the fan belt, and change the filter…
Depend on size of you air condition unit. You can do anything to prevent snow get in to the unit, which may put some weight on the fan and other component. Rain is not a problem. Simply thing is piece plywood over the top and few bricks to hold it there. Garbage bag and duct tap will work; of course manufacture may have their cover. HD may have a standard one. You may find cheap gas grill cover may work too. But don’t seal the whole unit; leave the bottom open, so the water can run out.
