The coil that serves the inside of the house is called the indoor coil. The reason is that the indoor coil is a condenser in the heating mode and an evaporator in the cooling mode.. (pg. 1077)
It is preferable to locate the OD unit above the ID unit to ensure that the oil does not accumulate in the evaporator over a period of time.
You don`t size a condensing unit to match your indoor unit. You size it to match the rate at which your house gains heat (heat load). Then you buy a matching indoor evaporator coil and set the fan speed on the indoor unit to deliver the proper cfm to support whatever size condenser the heat load calculation says you needed.
The indoor coil acts as an evaporator coil for heating.
Do you perhaps mean the 'lineset'? If so, it is usually a copper line (actually 2 copper lines) running counter-currently. They connect the indoor evaporator coil (above furnace or air-handler) to the outdoor condenser. One tubing carries the refrigerant gas from the indoor evaporator coil to the outdoor condenser and the other line carries the condensed (liquid) form of this gas back to the evaporator coil for it to be evaporated again and be converted back to gas. This is the refrigeration cycle of an A/C unit.
Unit is not cooling properly due to loss of capacity... Usual causes: air flow restricton dirty filter or evaporator coil, loose or broken indoor fan belt, indoor fan on too low a speed setting, if it has always been present undersized ductwork should be investigated or the system is low on refrigerant.
yes. Can also be referred to as indoor coil.
To clean your indoor evaporator coil, the contractor will most likely clear larger debris by hand or with a special brush, then follow up by applying a self-rinsing evaporator oil product. This product will clean the coil effectively and rinse off during the cooling process when the system is turned on.

Change the indoor filter, wipe the indoor unit down, and spray off the condenser
