Indoor/Outdoor Split Units
Indoor and Outdoor Splits are for installations where space is at a premium. Indoor Splits are smaller and more compact while outside systems are compact yet rugged to withstand the elements.

GeoStar split systems are engineered for installations where space is an issue. Their compact size allows use in places where packaged units would be unable to fit, like attics or crawl spaces. The Aston Split is often used as a secondary unit in the home for a more remote zone. An optional hot water generator is available on the indoor split to provide preheated water at amazing efficiencies. Use with a matching GeoStar air handler or ordinary gas furnace in a dual-fuel application.

GeoStar outdoor split systems are designed as an easy replacement to ordinary air source heat pumps. Their rugged, sealed cabinets allow use outdoors while still providing protection from the constant abuse of the elements. The loop pumps and earth loop connections are self-contained in the unit housing, eliminating the need for any indoor loop piping. GeoStar matching air handlers are available to complete the application, or couple it with an ordinary gas or propane furnace.
