      • Conduct infrared testing (if applicable)
      • Test for combustion safety
      • Install energy-saving equipment, including LED bulbs, programmable thermostats, and water saving devices (as needed)
      • Discuss our recommendations for additional energy-saving improvements
      • Review and screen for rebates and incentives available you may qualify for, including your eligibility for an ENERGY STAR refrigerator rebate. Mass Save offers weatherization rebates of 75%, up to $2000 towards the cost of the installation.
