Columbia Gas of Massachusetts participates in energy efficiency programs that reward eligible residential natural gas customers for utilizing energy efficient equipment or measures. The program pays residential customers 75% of the cost of recommended weatherization measures, up to $2,000. Columbia Gas of Massachusetts will perform a free energy assessment and provide its customers with a report listing energy-saving measures that qualify for incentives. If requested, the program can also provide their customers with a pre-approved independent installation contractor. Energy saving measures eligible for the rebate include: attic, wall, and heating pipe/duct insulation and thermostats. When needed, low-flow showerheads, and faucet aerators will be installed at no cost. Low-income customers are eligible to receive all of these measures at no cost. Additionally, up to $8,000 in incentives are also available for the construction of energy efficient Massachusetts homes.

In addition to this incentive, Columbia Gas of Massachusetts offers its residential customers a variety of rebates for the installation of energy efficient HVAC, water heating, and equipment controls incentives. Eligible equipment includes: furnaces, boilers, water heaters, and thermostats.  Rebates range from $25 to $1,200. All equipment must meet energy efficiency standards listed on the program web site.
