Customer Testimonials:

Home Energy Diagnostics transformed our house. Not only is our house much warmer, it is also a lot quieter. We are anticipating a significant reduction in our energy bill. Gail and Tom worked with us on a plan that worked for our situation. They helped us with the application process and were extremely responsive to our needs. We highly recommend Home Energy Diagnostics!

Glen Ridge, NJ

When I decided to insulate my 45 year old home I interviewed 7 companies. I found Home Energy Diagnostics to be knowledgeable, professional, reasonable and offering helpful ideas. After dealing with them I discovered they were reliable, prompt and caring about my home’s requirements. Also, Tom was able to design a cover for the attic fan eliminating a huge draft problem. Now that the work is completed I find my home to be warm and cozy. I wish I had done this years’ ago. Josephine

Home Energy Diagnostics is without a doubt one of the best companies anyone can ever hope to work with. I obtained quotes from several companies for my project and the pricing and customer service at Home Energy Diagnostics were by far the best so I felt quite confident contracting them but they truly went above and beyond. When you do any major work in your house you want to work with people who look out for you and that’s what they did for me, making sure all of my questions and concerns were addressed quickly and thoroughly and that I received quality work without spending any more than I absolutely had to. They were truly terrific in every way and I highly recommend them to others. Candy

Kearny, NJ

We figured that insulating our 100+ year old house would be disruptive and expensive, so we put it off. Then we met the folks from Home Energy Diagnostics and learned about the process and the government subsidies that were available. We’re so glad we did!

Tom & Gail held our hands through the whole thing: the paperwork, the energy audit, the work itself and the inspection. We highly recommend them! Debi & Alan

Montclair, NJ

After residing in my home for 35 years, I was finally able to enjoy the winter of 2016-2017 without having to wear a winter coat indoors. Previously, my home was devoid of any insulation. I was always aware of that fact, however I was unaware that the situation could be rectified without wreaking havoc on the physical structure.

Thanks to the expertise of both Gail and Tom, along with their “hands on” style, my house was transformed in approximately one week. The workers who did the work were proficient and treated the property with great respect. Within one or two days of the completion, some dust had settled, all of which was cleaned up quickly. Needless to say my heating bills were reduced, however it’s hard to say by how much because comparisons in energy costs and degree days vary from year to year. Michael B.

Ridgewood, NJ

Home Energy Diagnostics is run by an extremely professional team with years of experience. Tom and Gail are a pleasure to work with. I was worried about how I was going to insulate my home and I found this wonderful company who came in and worked magic. My home is now warm and comfortable. I highly recommend you give them a call. Beth G.

Tom and Gail are wonderful. Knowledgeable, efficient and professional. They helped every step of the way with getting the state rebate and the financing. Plus our house feels great! No more drafty living room and kitchen. AND our young kids are sleeping better in their newly insulated rooms. So, so, so worth it. So lucky to stumble onto this company. Caitlyn & Brian

Montclair, NJ

Home Energy Diagnostics is a fantastic company! Tom and Gail are both kind, patient and professional. From the initial energy audit through the completion of our home improvement project, we consistently felt confident in Home Energy Diagnostics and that our home was in great hands! We have already felt a vast improvement in our home and are grateful for the terrific work of Home Energy Diagnostics. We look forward to our continued reduction in our energy costs! We would be happy to recommend Home Energy Diagnostics to our friends and family! Andrea and Jesse

South Orange, NJ

I had been motivated for several years to improve the energy efficiency of my poorly insulated (1920’s) home in order to save money and also to decrease the extent to which I was contributing to global warming.  But I was concerned about the disruption the work would mean for our daily living.  Gail and Tom made the entire process as clear and simple as possible from start to finish.  Tom’s thorough initial evaluation and explanation of the leakage in my house led to a plan that Gail and Tom coordinated and implemented, including submitting all the paperwork.

They operate an extremely efficient firm but with a personal touch that I appreciated.  I began to have reduced electric bills immediately. Today was the first oil delivery since the work was completed and the bill is drastically lower than any previous bill (I’ve been in my home for 10 years).  And we are finally comfortable in the house in the winter!

Working with the team at Home Energy Diagnostics was an incredible experience. They are smart, kind, professional, honest and thorough.
We found the foam insulation experience to be extremely efficient.
There was a slight smell but it dissipated very quickly.
I highly recommend having your home insulated and using Gail and Tom. Tyrone and Jodi


Tom and Gail are the best. They provided personalized service, were very attentive, and held our hands thru the NJ state rebate process.

We are so happy that we made this investment, the house is warm and cosy after many years of living in a drafty 100+ year old house in Montclair. Above the savings on our energy bills, we are happy to have comfort in our home, especially during the winter months. Seetha Antoine


I would like to thank Home Energy Diagnostics for the great work and professionalism on our “project. We are so happy that we made this investment, the house is warm and cozy! Tom and Gail were fantastic to work with. Once again, thank you for such professionalism. James B.

A big thank you to both you and Tom. The insulation work went better than I could have expected. Both you and Tom were patient and answered all of my one million questions and alleviated my concerns. Both the gentlemen who worked on the insulation were professionals, respected my home and my impossibly high standards. They were extremely neat and careful and cleaned up at the end of each day. I am hoping we can now sit back and hopefully reap the rewards of lower energy bills and a more comfortable home. Nnea H.
