Our ductless systems (air conditioners and heat pumps) are very energy efficient. Since ductless systems have no ducts, they avoid the energy losses associated with ductwork of central forced air systems. Duct losses can account for more than 30% of energy consumption for space conditioning, even more if the ducts are located in an unconditioned space such as an attics and crawls.
They are much more efficient than ducted a/c’s. With SEER rating up to 30.5
