Do Ductless Air Conditioners Need To Be Vented?

Ductless air conditioners are the best alternative to central air conditioning and furnace systems. The installation process of ductless air conditioning usually does not take more than 6 hours. A ductless AC works similarly to central air conditioning. 

The process of heat absorption, condensation, and compressor is the same, but the way of providing the outcome is different. A ductless AC does not need any ductwork to transfer cool air into the room.
