18K BTU Mini-Split Systems

An 18K BTU system is typically suited to spaces around 600–800 sq. ft. Choose Easy Pro® for the best value, DIY® 5th Gen for higher efficiency and flexibility, Hyper Heat for very cold winters, or OuttaSight® for a discreet ceiling installation. Need comfort across several rooms? Choose a multi-zone system.
