    “Out in the middle of the night and I had no idea who to call.. I spoke with my sister the following morning and she had recommended your company. After your technician had arrived he figured out the problem in very little time, he was very knowledgeable and after speaking with him for some time, my husband & I decided to replace our Heating system with your company.. Which I might also add, was a wonderful experience. Our energy bills have dropped by 1/2... Thank you!!!” -Chris D., Alpha NJ

I had made appointments with 4 local companies, out of all them Trevor was the most knowledgeable, respectful, not just to me but also my home... During the installation, you didn’t even know they were here, I got to use the ac all last summer... And boy!! let me tell you, one of the best investments I could get for my home.. Hats off to Trevor and his crew at Garden State Energy.. I will always refer them to my friends and family.” -James P., Whitehouse Station, NJ
