At Home Efficiency Experts of Long Island, we provide free energy assessments to homeowners.

We then take the time to walk our customers through our findings, providing them with cost-saving solutions and recommendations for home improvement.

We work hard to provide the best solutions in sealing, insulating, heating, and cooling your home, using the best materials in the industry. We keep your home warm in the winter and cool and comfortable in the summer. In the process, we save you money and provide the comfort you expect, while also adding value to your home.

I was skeptical about having an energy audit done on my home. The process was easy and the work they did on my home was done professionally and timely. Bill came to the house before the work was done, and went over the whole project with me. I felt completely comfortable with the entire process.
