Insulating draft from in wall heating and cooling unit
Hi. I have an in wall Carrier Heating and Cooling unit (electric). Its fine when turned on...provides good heat and ac. When it is off, which is often in the winter the unit is very drafty basically letting the cold air flow right into the apartment. Question - are there any products (or creative ideas) on how to cover or insulate the unit while it is not being used to prevent this draft.
