What can I use to keep my air conditioner from blowing?
Foil-faced-bubble-wrap is only really effective if it’s installed with an air gap around the duct, so unless you’re going to build a shell of fiberglass or foam. The gains still won’t be as big as from stopping sunlight from coming into your room, but it may be worthwhile if you’re not moving the air conditioner frequently.
In a properly working air conditioner, the fan will draw air over the cold evaporator coils and then re-circulate the air back into the room. If the circulating fan is not running or running too slow, little or no air flow over the evaporator coils will allow them to become too cold and frost or ice can form, restricting the air flow even more.
The thermostat will also cycle the compressor off when the desired temperature has been reached. If the temperature control or thermostat is defective, it may not send power to the compressor, and no cooling will take place. Inspect the sensing bulb for any signs of a sharp bend, kink or rupture and replace the control if any are found.
