How to Receive Benefits from the Commercial and Industrial HVAC Program
Determine Your HVAC Needs
Contact your HVAC contractor to determine the heating and cooling needs for your business.
Find a Participating Distributor
Please use the tool above to locate participating distributors who can work with you and your contractor to identify the right kind of high-efficiency equipment for your business.
Start Saving Energy
By purchasing high-efficiency HVAC equipment you may benefit from the energy savings over the lifetime of that equipment.
The following are suggested steps for maximizing your savings:
Equipment: The program covers several types and sizes of commercial air conditioning and heat pump units, including VRF systems, ECM Pumps and Dual Enthalpy Economizers. These high efficiency systems help you secure even greater energy savings, which you can learn more about here.
All equipment performance specifications are verified through the Air-Conditioning, Heating, and Refrigeration Institute (AHRI), or otherwise approved by the Mass Save Sponsors. You can visit the AHRI website (www.ahrinet.org/Home) to research eligible equipment or contact the Program Implementer for more information.
Location: Businesses paying a non-residential rate from any electric Mass Save Sponsor in Massachusetts are eligible. Qualifying equipment must be installed and operated at the eligible customer’s premises in Massachusetts.

What’s a Unitary Heat Pump?
A unitary heat pump (HP) operates on the same principles as a unitary AC system, but is able to provide heating as well as cooling by reversing the way your air conditioner operates. In the summer, it rejects heat to the outside to cool your building, but in the winter the cycle is reversed and the unit rejects cooling to the outside and is used to heat your building. Unitary AC and heat pump systems use ducts to transport air through a building (similar to having central AC in a home).
What’s a Mini/Multi-Split Heat Pump?
Mini-split heat pumps are efficient HVAC systems that can produce cooling for the summer months and heating in the winter months. A mini-split system is composed of two components: an outdoor condensing unit and one or more indoor air handling units. Ductless mini- and multi-split systems use refrigerant lines, rather than ducts, to transport heating and cooling through a building. The indoor fan coiled unit blows the cool or warm air into the space. Multi-split systems have multiple indoor units that provide heating and cooling to individual zones within a building.
What’s a VRF System?
Variable Refrigerant Flow, or VRF, systems are efficient HVAC systems that can produce cooling for the summer months and heating in the winter months. A VRF system is also composed of two systems: one or more outdoor condensing units and two or more indoor air handling units. Like ductless mini and multi-split systems, a VRF system uses refrigerant lines, rather than ducts, to transport heating and cooling through a building. VRF systems can be installed with a central control box that can modulate the heating and cooling to individual zones within a building. In the winter when the outside of a building needs heating and the inside of a building needs to be cooled (from high internal heat loads), a VRF with a control box can move the heat from one space to another without using additional energy, allowing for more efficient operation when both heating and cooling are needed. VRF systems are modular systems that start at 5.4 tons and can be used to cool spaces up to several hundred tons. Multi-split systems, described above, supply less than 5.4 tons of cooling.
What’s a Dual Enthalpy Economizer Control?
Dual Enthalpy Economizer Controls are an add-on to unitary AC and HP equipment that reduce energy use by enabling the equipment to more efficiently modulate its performance to match the desired indoor conditions. The controls are typically integrated either during manufacturing or as after-market components into equipment featuring an outside air economizer. The Dual Enthalpy Economizer Control assess the temperature and humidity of the outside air and return air to determine the best way to cool the space. In instances where the outdoor air is at optimal conditions for cooling, the controller uses outside air to cool the building, instead of using power to mechanically cool the air. This can dramatically reduce the run time hours of an AC or HP.
What is an ECM Circulator Pump?
Electronically Commutated Motor, or ECM, Circulator Pumps are efficient pumps that use intelligent speed to adjust the flow rates of water within heating and cooling applications to meet demand. This process saves electricity and improves overall system efficiency. ECM pumps adapt to partial load situations more efficiently than single speed split phase models.
