Ice all around outside unit - Heating & Cooling

An ice build up around the top of the door aperture isn't unusual due to some cold dense air from inside will spill out when the door is opened to be replaced with humid lighter outside air that will tend to remain at the top for a while.

Being frost free doesn't exclude it from this type of ice build up as only ice formed over the evaporator during a cooling cycle will be melted by the defrost heater.

Persistent localised ice build up could be a sign of failing insulation but this will be marked by a cold spot on the outside of the cabinet.

have the gas pressure checked by an accredited ac specialist
ice forming on tubing is an indication of liquid in a low pressure line boiling off so that indicates a pressure problem
also any tubes from the outside unit to the evaporator should be insulated properly to prevent icing and loss of efficiency
inside / outside is not the problem , it is the air around the pipe that has humidity that allows the ice to form in the first place

check indoor coil before that can happen unless it's a heat pump it should also be iced up.

No that is not normal. Your AC unit may be low on refrigerant coolant and needs to be recharged. If it's low, there's probably a leak, which is causing the ices on the outside unit. Contact a qualified service technician to check & service the unit.

Depends on the outside temperature as if the temperature is lower there will not be heat exchange and so frosting can happen.

take a garden hose and wash the unit real good,if the unit outside cant breath this will cause it to freeze up

Ice is forming as the humidity (moisture) in the outside air condenses and freezes on the colder parts of your unit.

If the inside fan motor is running OK you are low on refrigerant. If the inside fan motor is not running, repair the inside fan motor. Could also possibly be dirty inside coils.

Freon is low. Sounds counter-intuitive, but the large return line should be cool( even have condensation on it) but never cold enough to freeze.Either use factory pressure settings or add just enough Freon until Ice melts. If unit has a high-side sight glass there should be no bubbles present. Do not overfill.

Clean the filter!
