Energy Efficiency Feels Good!

When we “retrofit” your home with energy efficiency improvements, you’ll be more comfortable, warmer in the winter, and cooler in the summer. Your impact on the environment will lessen and you’ll  save money on your energy bills too, now that’s going to feel good!

New Jersey’s Clean Energy’s program, Home Performance with ENERGY STAR® can make the installation of improvements quite affordable, they offer $4,000 in rebates and 0% financing of up to $10,000 for qualifying improvements.

Give us a call to see if you might be a good fit for the program’s generous incentives.

Get up to $14,000 of Energy Efficiency Improvements with No Upfront Cost!

Here’s how it works: The Home Performance rebates can pay for up to 50% of the eligible measures ($4,000 max) and the 0% loan covers the balance ($10,000 max). That’s $14,000 in improvements without any upfront cost to the homeowner, just a monthly loan payment after improvements. Energy bill reduction offsets the cost of the loan.

Energy Audit and Energy Efficiency Retrofit Plan

Step 1:

Step 2:

Secure Rebates & Financing

Before we proceed with efficiency improvements we’ll secure your rebate and verify that your 0% financing is in place. Most of our clients have no upfront costs, thanks to the HPwES incentives. The rebates are awarded based on the total estimated savings after improvements.

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!

For Sale: Space heater. We no longer need this to heat our home office, now that Home Energy Diagnostics has worked their magic.Our entire home is cozy warm, even with outside temps of 10 degrees. And our energy bill is a fraction of what it used to be! Paul & Sydney

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

Parlin, NJ

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

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!


Maplewood, NJ

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
