  • I signed up for an audit at the Smithtown Day festival. They came and did the audit and were very nice. They insulated my attic and changed all my light bulbs. I can't wait to see my savings this winter.

    Tina, St. James
  • I must admit that when I completed the LIPA energy audit and found out that an outside company will be doing the audit, I was skeptical. But, as an energy conscious consumer I kept an open mind. My doubts dissapeared from the first contact with your company.

  • This company is efficient and professional. Working with everyone involved was a pleasure.
