The Sycamore Series is our most impressive system yet. With an amazing 41 EER and 5.3 COP, the Sycamore is more than twice as efficient as ordinary heat pumps and a third more efficient than current dual capacity geothermal heat pumps. A variable capacity compressor works in concert with a variable speed blower motor and variable speed loop pump to provide the utmost in comfort and groundbreaking efficiencies. The Sycamore ramps itself up or down to provide exactly the output your home needs at any given time while also offering soft start capabilities. This eliminates light flicker and provides ultra-quiet operation. Add in the Aurora family of controls for two-way communication and energy monitoring capabilities, and you have one of the most advanced heating and cooling systems on the planet.



The Sycamore can handle heating, cooling, and hot water assist all in one unit—no need for a noisy outdoor air conditioning unit.

Variable Capacity Compressor

Variable capacity compressors offer soft start capabilities and gently ramp up to speed for quiet operation while also eliminating light flicker.


Powerful Aurora controls offer two-way communication between components, industry-leading operating logic, and thorough troubleshooting capabilities. An expansion board adds true energy monitoring capabilities, extended hot water generation control and more.

Variable Speed Blower Motor

A variable speed ECM motor runs at only the speed needed for maximum efficiency and savings. When Active Dehumidification is enabled, our Aurora Controls optimize the blower to remove the maximum amount of moisture.

Coated Air Coil

A layered coating protects the air coil from corrosion extending the life of your system. Its large size improves efficiency and provides better dehumidification during cooling.

Aurora Interface Diagnostic Port

An external communication port allows service and diagnosis of our units without ever having to open them.

Filter and Filter Rack

Pleated MERV 11 filter is standard while an optional pleated MERV 13 is available for improved air quality. Filter rack holds 1” or 2” filters and is field convertible.


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

Advanced Hot Water Generation

With an optional hot water assist, the Sycamore preheats your water and delivers it to your water heater. A sophisticated microprocessor controls and monitors heat pump conditions and determines when there is excess heat available to route to the hot water heater. This allows you to utilize heat in the most efficient way possible.


The cabinet comes with a durable powder-coat finish for long-lasting beauty and protection. The system is fully insulated for quiet operation with cleanable foil-backed insulation.
