“Apple energy has done an exemplary job in meeting our needs here at the Governor’s Energy Office. Their experience and ability to explain the processes of running NEAT and MHEA to our local administering agencies has been an excellent tool to keep our Weatherization program in line with Doe regulations.  Their communication and commitment to the project has been of the highest caliber. Response time has been quick, concise and helpful.  I wish to thank Greg, George, John, Jim and the entire team at Apple Energy Group for their part in the success of our program, and I look forward to working with them again in the future.”
