One afternoon my husband was approached by a door to door advertiser for Energy One windows. She wanted to know if we were interested in replacing our windows. At the time we were not looking to replace our older windows, however I decided to make an appointment with them to get more information on the new Energy One windows. A few days later a representative from Energy One came to our house and explained about the efficiency and durability and how beautiful the windows look. The representative was very professional and knowledgeable about the Energy One windows. He had my husband and I sold with the security and energy efficiency. There is such ease with cleaning the inside and outside of the windows, with the way they flip inward. The price of the windows was within our budget. It took a few months to install the windows due to manufacturing and the weather. But overall it was well worth the wait. It took 2 days to install the windows and sliding glass doors (3) . The installers were very professional, knowledgeable and educated us on the mechanics of the windows, which are very easy to use. Overall I believe and strongly feel that Energy One was the best choice for new windows in our 1979 home. Adding the new windows has upgraded our homes curb appeal and has provided peace of mind knowing that we are safe and secure in our home. Thank you, Melissa Gutierrez read more

Energy One did an outstanding job on our windows! From the initial contact made by the sales rep to the contact made by the office staff for the re- measure and installation, EVERYTHING was on schedule. The office staff was professional and extremely helpful. Courtney the scheduler was great, she worked around our schedule for the installation and was a delight to work with. The day of installation, the work crew showed up on time, replaced 12 windows in 4 hours! We were concern on how they would do with the windows and the siding on our house. The installers did a fantastic job removing and reinstalling the windows and the siding was perfect! They cleaned up all debris inside and out. Houston, the foreman took the time to show us how to operate the windows and care for them and answered all of our questions. These windows have made such a difference in the appearance of our house and how quiet and cool it is now. This was a great experience, we would highly recommend Energy One to anyone. We think they should change their company name from Energy One to "Energy Won-derful!" read more

From the very beginning of our venture with Energy One it has been a great experience!!! They finished the install this morning and we are so pleased with the product and the beauty it adds to our home :0) All the staff is awesome - We first met Courtney who had lots of knowledge and made our appt with Charles. Our appt with Charles was awesome, he was knowledgeable and friendly like he had known us for years! We felt confident in our purchase with Charles that day because of the knowledge and excitement he has for his product. Then came the install - Houston and his crew were great guys and their work was seamless - they made the install go soooo smooth, they installed 13 windows and a sliding glass door in a day WOW!! Then came back this morning for doing the final touches. Maria in the office was very helpful and great to us as well.

This company is the one to choose when you want your new Windows!! Thanks again Jon & Roberta Whitley read more

Over several years we have gotten many estimate for Replacement Windows and all were too expensive and/or of lesser quality than we desired. By chance we found Energy One Windows.Com and could not have been more pleased.Their personnel are extremely knowledgable, proficient and professional. The explained the entire project, the windows etc in great detail until we were ready. At that point their Administrators, Installers and crews all worked very diligently and deftly to install windows that are spectacular in appearance and have definitely improved the appearance of our house and its curb appeal. I am sure that over time the windows will repay us in energy costs and improve our comfort level in our home. The windows have already proven to be a great sound barrier as outside noise have been muffled dramatically. We are very pleased with the overall project and recommend EnergyOneWindows.com to anyone interesting in quality windows and service If you live in Garden Ridge area come by for a drive-by look.

Great company to work with. The sales people demonstrated all aspects of the window (they brought a sample) and were not pushy in any way. They made recommendations and listened to our preferences. After we agreed to the purchase, a crew came out to (re-) measure the windows for production. Once the windows were delivered, we set an appointment (in the hopes it would not rain) and the installation crew started working. Mr. Houston was the installation crew contact and he is awesome. All of them were very courteous and friendly and certainly hard working. They had to come back the next day to finish the job (due to some delay in getting the old windows out) and Houston adjusted his schedule to make sure I was available. - I also have NEVER experienced such clean working contractors - they cleaned up after they finished each window, vacuumed and were very respectful of our belongings - inside and outside of the house. Again - great company. read more

Energy One High Performance Windows are just that ... number ONE. We are very pleased with the windows which deliver what is advertised - outside noise reduction, heat reduction due to the sun shining through the windows and in South Texas you can really appreciate the house inside staying cool, and outstanding quality and workmanship. We are sure the enhanced appearance of our home due the windows and their molding definitely adds to the value of the house. We are more than satisfied with the work crew: Houston, Mike, and Lorenzo. They were more than professional and courteous. They worked as if they were installing these windows in their own homes. They readily explained what they were doing step-by-step, and fully answered all our questions. Wish there were more crews like them and their conduct attests to the quality and standards of Energy One. read more

Our house was built in the early '80. New windows were not an option anymore ... We found Energy One through 'word of mouth' and online reviews. I never heard of them before, but have to say I can highly recommend them. Not only was the presentation of their representative clearly structure, but honest. The focus was more on product quality then assumed future energy savings or tax refunds. To my surprise all windows are custom made no standard sizes. So they fit perfectly. Especially when you plan for a retrofit project, that is important. The installation was as smooth as possible. The crew finished with good quality work performance in just two days. Over all we would use Energy One definitely again. - Michael, San Antonio, TX read more

Customer service was outstanding! We were kept informed by phone and email every step of the way. Installation was adjusted to fit our schedule with no issues. The windows are fabulous. So easy to operate with snug-fitting screens that work both top and bottom. We love that the windows swing in for easy cleaning. They also block out nearly all street noise. The installers were very professional and did a GREAT job, including adding mortar around all the frames that were set into our stone exterior. The windows look like they were built into the house! We are looking forward to much lower heating and cooling bills with these superb-quality triple-pane windows. Thanks Energy One! read more

Love, love, love the windows from Energy One. The sales and install team did an incredible job. The install team was always totally professional and exceeded my expectations as they replaced all the windows and sliding glass doors. The work site was left spotless upon completion and I couldn't be happier with the results. I can already tell the difference the new triple pane (double-hung) windows are making as my AC is not running as long in this 95+ July heat wave. I would highly recommend Energy One as a preferred vendor for anyone serious about replacing their windows to achieve energy conservation. read more

Original windows were from mid 1970s and single pane. Can tell definite improvement in energy costs and ease in cleaning windows. Installers were very courteous, experts in their craft, efficient, and cleaned up. Without hesitation, recommend company and windows. read more
