Indoor Splits are for installations where space is at a premium. When combined with a GeoStar air handler, the unit can provide complete home heating & cooling. When added to a furnace, the system will automatically switch to the most economical heating source for energy conservation. All Aston units utilize R-410A refrigerant. The Aston Series Indoor Split provides the amazing efficiency of geothermal in a conveniently small footprint.

*It is recommended to install a GeoStar air handler with the Aston Indoor Split. The US Federal tax credit is only applicable when the GeoStar air handler is installed with the split unit.



New exterior design elements put the Aston Indoor Split in the same class as today's stylish high-end appliances while full insulation provides for quiet operation.

Hot Water Assist

With an optional hot water assist, the Aston Indoor Split can take water from your hot water heater, preheat it, and redeposit it into your water heater – making it so there is less work for your hot water heater and lower electric bills for your wallet.


Copeland Scroll compressors are featured in all Aston products for superb efficiency and reliability. Dual capacity units include Scroll UltraTech compressors mounted on double isolation plates for extra-quiet operation. Dual capacity means the compressor can run at two speeds based on the needs of the system – the compressor may run more frequently but it will be running much more efficiently, similar to the difference between highway driving and city driving.


A sophisticated microprocessor sequences components to provide ultimate performance and reliability. These controls communicate with your thermostat to display service messages so you can relax, knowing your system is performing to its highest capability.

LED Status Lights

Externally mounted status lights indicate normal operation or display problems to assist the technician in troubleshooting.


All GeoStar units use R-410A - an environmentally friendly, non-ozone-depleting refrigerant that enhances efficiency and savings.
