High-Performance Heat Pumps (Air to Air)
High-performance heat pump units can be used by businesses for both your heating and cooling needs while saving energy and money. Units must meet the minimum HSPF (Heating Season Performance Factor) requirements in order to qualify for incentives from Efficiency Maine.

Variable Refrigerant Flow (VRF) Systems
Variable refrigerant flow systems can simultaneously heat and cool different parts of a building. These systems can be very efficient because they can take waste heat captured in one part of the building (e.g., a server room, or the face of the building exposed to the sun) and deliver it to spaces requiring heat. Because they rely on a different distribution network than is present in most existing buildings, variable refrigerant flow systems are most often installed in new buildings or as part of large renovation projects.

Packaged Terminal Heat Pumps
Packaged terminal heat pumps are heating and cooling systems used for individual rooms, typically seen in the hospitality industry. These “through the wall” systems are self contained with a permanent electrical connection. Outdoor air is used as a source of heat in the winter and cool air in the summer through a distribution fan.
Water Source Heat Pumps
Water Source heat pumps are systems that use the constant temperature of the ground (geothermal) below the frost line to heat and cool throughout different seasons. The water source can also be achieved by using high efficient hydronic boilers and a cooling system such as a cooling tower. Click here for more information.
