Mass Save Home Energy Services

After contacting Mass Save, energy efficiency specialists will answer your energy-saving questions and determine your eligibility for a free Home Energy Assessment. The assessment includes an analysis of your home's energy use, advice for saving energy and rebate offers on recommended energy improvements.

NSTAR customers who heat their homes with oil or propane are also eligible for mail-in rebates on various high efficiency products. More information, including rebate forms, is available in PDF format. Available mail-in rebates include:

• A $25 rebate toward the purchase and installation of an ENERGY STAR-qualified or seven day thermostat that controls an oil- or propane-fired heating system.
• Up to a $500 rebate toward the purchase of a new high efficiency oil- or propane-fired heating system.
• A $300 rebate for customers replacing an existing oil- or propane-fired tankless or freestanding hot water heater with an indirect fired water heater.

Additional incentives include 75 percent off up to $2,000 toward insulation upgrades and 0 percent financing for qualified customers from the HEAT Loan program.
