From the evaporator coil, the refrigerant travels to the compressor.

HVAC tubes are measured by outside diameter as opposed to “pipes,” which are used in plumbing and measured by inside diameter.
A two-stage furnace refers to the valve that regulates the amount of gas supplied to the burner. The valve can open fully for maximum heating capacity or open partially (half) for less heat output. The motor of the blower can be two speed, multi-speed or variable speed. The ability to regulate heating allows for increased energy efficiency and a steady, more balanced room temperature, compared to a single-stage furnace. A two-stage furnace typically runs at a low speed most of the time and automatically switches to the second speed, high, only when temperatures are very cold.
