Answer to Question 1

The return air enters at the fan housing end of the furnace and travels to the heat exchanger end.

Answer to Question 2

40 VA ratings are needed for air conditioning because electrical devices containing a coil and iron, such as solenoid valves and relays, have a power factor of approximately 50.
