Eric Gans - Certified Home Energy Auditor

Home Performance Maryland Contractor

Helping Maryland residents connect the relationship between home comfort & energy efficiency.


I would always emphasize to my window and siding customers how all of the exterior parts of your home work together. 

At the time, like many in my field, I failed to see how they connect to the inside of a home as well.

Now I use three dimensional thinking to give YOU the best possible information and advice. 

With over 2000 home energy audits under my belt in Maryland, I know the places to look and I can show you!

A Different Way to Think

Who has time to think about building science?

The problem is that we live in buildings and without a few key insights it won't take long to get on the wrong track when trying to improve comfort and lower energy consumption.

I went down the wrong rabbit hole myself a few times and it took me twelve years to figure it all out.

I can teach you in a few minutes.

If you care to learn more...all of this started in hotels...


Hospitality Came First

In 2006 I left a five-year career with Hilton Hotels Corporation.  I had a great role and boss with the Embassy Suites in Old Town Alexandria, VA.  

In the hotel business people and high quality service are the top priorities.  It came naturally to me and I received recognition for my work while with Hilton.

Teamwork is also important.  Coordination, proper management techniques and attention to detail make a hotel operation flow smoothly.

As it turns out, running a successful hotel is much like running a successful home performance project that pays off.

The Start of My Exterior Remodeling Experience

In 2003 a friend started a small window company and gained some momentum and wanted me to help.  I had never worked in the home improvement industry at the time. 

We focused on the overall process and the customer experience and the company quickly took off and lasted for twelve years.


I immediately felt as though I was in the right place.  I loved to experiment with new products such as demonstrating how laminated window glass works to add safety by smashing it with a baseball bat.  I am the guy in the red jacket in the video from 2008.



My curiosity did not end with windows.  During that time I learned about other important home improvement projects such as siding, roofing and gutters.

Read a small portion of this testimonial from 2013.

Although reviews were good and the focus was always on customer service and quality materials, other factors lead the company to shut the doors in 2015.   


Setting a New Path in the Maryland Home Remodeling Space

Soon after, I took on roles with other local contractors and I realized that I was lacking passion.  I liked helping others make improvements to their home, but something was missing.

In 2017 I discovered a fascinating way to help.  Home Performance!

Air sealing, attic insulation, proper ventilation and low-cost HVAC improvements are a few on the list. I was eager to learn more.

The required certification was one-part science and one-part residential building knowledge. I turned out to be a great fit and earned my Building Analyst certification through the Building Performance Institute at the end of that year.  

Later, after conducting a home energy audit on my own house, I had a positive personal experience with the rebated insulation work in my attic and it was on!

If you have ever had that happen to you, maybe you can relate.

It's when you can successfully bring something you learn professionally to your personal life. It has a profound effect on your excitement to spread the word! 

Building science principles took on a new meaning to me and I now believe every homeowner should learn a few key concepts that can go a really long way towards better comfort, saving energy and putting money into the smartest places around the house first.

These days, I have earned all of my licenses and I help Maryland homeowners solve their home comfort issues and lower their bills.  BGE and Pepco customers are signing up for the work through the Home Performance rebate program and the results have consistently been very good.
