Boilers & Furnaces

Energy efficient heating system in Massachusetts

Consider replacing your boiler or furnace with a high-efficiency heat pump. Heat pumps provide both heating and cooling in one unit and can be installed with or without existing duct work. The Sponsors of Mass Save offer rebates up to $15,000 per home on qualifying heat pump systems. Greater discounts and no-cost options are also available to income-qualifying customers.

Paired with weatherization upgrades (insulation and air sealing), upgrading heating and cooling equipment is one of the most effective ways to lower your energy use.

In addition to incentives, you can also take advantage of federal tax credits to further lower the price of purchasing and installing a heat pump water heater.

For an existing boiler or furnace, regular maintenance is recommended to ensure maximum efficiency.

In alignment with the commonwealth's climate policy and goals, including a mandate passed into law by the 2021 Climate Act, rebates, incentives, and financing for equipment powered by natural gas, oil and propane are no longer available. The only exception is for income-eligible households. Incentives remain available for income-eligible customers upgrading existing fossil fuel equipment to high efficiency models.
