Heat Pump Solutions for the Merrimack Valley

For Residents Impacted by the Recent Gas Incidents

Interested in Using Electricity for Heating?

If you’re planning a switch to electric heating and water heating, Mass Save has resources available to help you make the most energy efficient choices. That includes rebates that lower the cost of qualified heat pump solutions, and trained contractors to assess your home and ensure proper installation.


Central Heat Pumps

What’s a Central Heat Pump?

A central heat pump operates using the same type of duct system as a central AC system or furnace, but is able to provide heating as well as cooling by using the difference between outdoor air temperatures and indoor air temperatures to cool and heat your home, while saving you on energy costs.  Mixed ducted systems also use ducts to distribute heating and cooling, but involve the installation of new ducting dedicated just to the heat pump and may be installed along with ductless units as well.

Installation considerations:

  • Duct sealing: Proper duct sealing can reduce heating and cooling costs by as much as 15%.
  • Airflow: An AC-check trained contractor will check that your system has proper refrigerant change and airflow to get the most from your system.
  • Sizing: Oversized equipment costs more, uses more energy, and can fail to properly dehumidify your home. Your contractor should make sure you have the right system for your space.

Mini-Split Heat Pumps

What’s a Mini-Split Heat Pump?

Mini-split heat pumps provide dependable heating and cooling and can save up to 30% in energy costs by moving heat rather than working overtime to generate it. In the hot summer months, heat is moved from inside to outside, while in winter the process runs in reverse, extracting energy from outside air and converting it into heat for your home.

Installation considerations:

  • For whole house use, work with your contractor to make sure there is enough capacity and that indoor units are placed appropriately. Multi-head, cold climate models are a good option for whole house heating and cooling, and function efficiently down to very low temperatures.
  • For optimum performance, have your contractor size the system to meet your needs. A system that is too large wastes energy, and a system that is too small will not provide proper comfort.
  • Note that systems that include the installation of both mini-split and ducted heat pumps are considered mixed systems, and qualify for the rebate amounts listed above.
  • Once your mini-split system is installed, set it and forget it! Leaving this system on full time optimizes your home’s comfort and efficiency. Designed to run continuously, the system will auto-adjust as the room reaches the desired temperature setting.

Effectively using heat pumps with your existing heating system can reduce heating costs for customers who heat their homes with oil or propane. By installing an Integrated Control, the system can automatically switch from heating with your Air Source Heat Pump to your conventional system based on preselected outdoor temperatures. This allows for maximum comfort and cost savings throughout the winter months.

What You Should Know
  • Heat pumps can be installed by any MA-licensed HVAC contractor.
  • As with any home improvement, it is good practice to obtain quotes from multiple contractors.
  • Integrated Controls must be selected from the Integrated Controls Qualified Products List to be eligible for rebate. Mini-split heat pumps must be selected from the NEEP Cold Climate Air-Source Heat Pump Product List to be eligible for rebate.
  • Typical objectives of installing a mini-split heat pump can include:
    • Reducing the amount of heat supplied by oil, propane or electric resistance
    • Heating and cooling the whole house
    • Heating and cooling an individual room
  • Regardless of your objective, be clear about understanding what size unit is right for your space, and how your mini-split heat pump will perform in freezing temperatures.

As with any heating system, mini-split heat pumps are most efficient if your home is well insulated and drafty areas are air sealed.

Additionally, residential customers of the Mass Save® Program Sponsors can receive a rebate of up to $600 if they have a licensed plumber install a qualified heat pump water heater when replacing an existing electric storage tank water heater, or building a new home.
