Electrify to decarbonize

All-electric heating and cooling supports compliance with policies and incentives to decarbonize buildings. Heat pumps move heat rather than generate it, making them up to three times more energy efficient than other forms of electric heating.


Reliable cold weather comfort

Vapor injection technology extends the effective operating range of the scroll compressor to provide reliable comfort in colder climates. It enables leaving water temperatures of approximately 130°F at 0°F outdoor ambient temperature.

Modular flexibility

Easily expand to the capacity you need. Install where space is limited. Air-source units move easily on freight elevators and fit into tight outdoor spaces, such as urban rooftops. Smaller refrigerant circuits enable tighter temperature control, too.
