Amazing response and amazing job done, in a short amount of time. I have known for awhile that I needed more insulation in the attic. I started to search for insulation companies in the area. I quickly started seeing a pattern with reviews on other companies. All of them were, "called 15 times, never called back", "agreed on a start date but never showed up", "showed up but didn't know what was needed"... I was dreading making any decision on who to call. But then finally a company stood out above all the rest, Energy Nerds. I called Mike and left a message. He called back within an hour and even apologized for not calling back sooner! What?!? I called him on a Friday afternoon, he said he would be out Sunday afternoon and the job was completed by that evening! Truly amazing work done in a short amount of time. Mike and Dustin are great friendly people. Very knowledge in cutting edge technology to help you save money with energy costs. Mike is well informed so if you have any other energy saving needs, please talk with him. I would not hesitate to hire them again. Truly a pleasure to work with.

We are just starting to discuss but I'm happy with how I feel about being informed and listened to. I understand the what and whys of his recommendations. Understanding and feeling comfortable with what is to be done at our new home is a big relief.

Energy Nerds service was good & their BetterAir Biodify air purifier works putting probiotics in the air for better breathing & better health! I first used the small one by my bed & then went to the whole house one. I am 80 years young. I had a croaky voice for months which caused me concern. I wouldn't want to be without it. I feel blessed! Cecilia Neis

I wish I could give them a 10 star rating!!! I would recommend Energy Nerds, without reservation to my family, friends and anyone else who values a job well done at an affordable price. They provided excellent value and it has made a difference in the comfort level in my century old home.

The owner was extremely professional and helpful. He explained alternative methods of 

accomplishing what I was interested in doing and ended up saving me a lot of time and money. Would 

recommend.

It was really, really good! They did a very professional job. I had lost my little diamond ring and one of the installers actually found it in my driveway and brought it up to me!
