The loud noise from the AC when turning off is often caused by the sudden release of built-up pressure in the system as the compressor shuts down. This pressure release can create a loud "whooshing" or "popping" sound.

The "boom" noise you hear when a furnace shuts off is usually due to the rapid cooling of metal components inside the furnace, such as the heat exchanger or ductwork. As these components contract quickly from the sudden temperature change, they may produce the loud noise you hear. It is typically harmless, but it's a good idea to have a professional inspect the furnace to ensure everything is functioning properly.
