We had our windows installed back in April 2017 & 1st of all I would like to thank Jymi for his overall sales on the Quantum Green Energy Windows. He was very knowledgeable and was able to help us decide what we wanted. 2nd I would definitely like to thank David (installer) for his overall knowledge and help with installing all of our windows in our home. It took a bit longer than expected (which was fine), but he and his workers did a great job in making sure the windows were put in correctly and the other items that needed to be taken care of were done neatly and in a professional manner. He would come in on time that day and explain what was going to happen. If we had any questions or concerns, he would answer them quickly and/or get it done for you. At the end, he did make us do a walk thru to make sure the windows were done to our satisfaction, if not, he would take care of it for us!! He's AWESOME!! 3rd Thank you Aimee for taking the time to process our paperwork and finalize our payment. We will DEFINITELY recommend Green Energy to our family and friends!!Less

From beginning to end, our experience with Green Energy of San Antonio was amazing. When my husband and I first talked about getting window replacements, I told him I would ask for recommndations from our church. Someone recommended Green Energy and said they were a great company. I began researching online for who might be reasonable and had good reviews. I also did a comprehensive search on the different types of windows that were being offered online. I really wasn't impressed with any of them. They were ridulously expensive. Then I found a video on the Green Energy of San Antonio, that came out on TV and demonstrated how strong and effecient they were. I told my husband, Tom, he needed to watch it. We were both sold on the windows. I made an appointment and they came and explained eveything in details, how the window works, how the radiant barrier worked, and the pricing, which was way cheaper than other companies were trying to get from us. They were very professional, curtious, and listened to exactly what we wanted. When it came time to order and install the windows, they kept in contact with me from the start to finish. We love our windows and it has made our home look even more beautiful. It has also added to the value of our home. As promised, there has been noise reduction, I have had to turn the thermostat up becuase the temperature we had set it on for years, now felt much colder in the house than before we got these amazing windows. David, Richard, and Emilee, thank you all so much for making this such a pleasurable experience. I would totally recommend this company to anyone who is looking for good quality windows with very reasonable pricing. God bless you!

I signed up for a Google account just so I could write a review for Green Energy....and that alone speaks volumes. Everything from the consultation, to the precise detail of the installation was nothing but first class. Due to the sun at our house, we had a hybrid of glass styles, and also had various shapes for picture windows and double hung windows, and it all turned out fantastic. I can't say enough about the experience, and David, their installer, is the most professional and courteous man you will ever work with. There's honestly no other place you need to go once you worked w/ these guys. Thank you.

Very reputable company. I hired them to put windows in a home that I sold, and then hired them to do the new house. On one of the house's we ran into a stucco issue, and they stayed with it until they got it right. Highly recommend.

I can’t say enough good things about Green Energy of SA. First, Richard came out and gave his presentation and explained the difference between his windows and other windows, why he did what he did, and how he was able to do what he does at such a competitive price. He left us with an estimate, and asked us to call him or his office with any further questions. I called 2 or 3 times with a few questions over the weeks that we were narrowing down our decision. After much though, we decided to move forward. We really appreciated the “non-pushy” sales approach that Green Energy provided. It seemed as if they really wanted us to make the best decision for “us”. When we were ready, we coordinated with their installer, David. He’s really top-notch, by the way. David came out, measured the windows in few minutes. A few weeks later our windows were ready to install. 2 days later we had 9 new windows. Super easy, no B.S., honest, quality business. How it should be. Thank you all.

My experience with Green Energy of San Antonio has been nothing short of outstanding. From my first introduction to this company at the 2016 Leon Valley Earth Day exhibit to my final service purchase in April 2018, the company has consistently delivered on its promises of quality materials, price quotes, superior technical installation skill, and stellar customer service. I had all my custom-sized windows replaced and I have never met a team of installers as skilled as those who work for Green Energy. Living in a rather congested (now) part of town, those windows and their meticulous installation have made a huge difference in my quality of life. This year I decided to have insulation blown into my irregular-shaped attic; the excellence of the insulation materials and the expertise of the installation team once again contributed to improved home quality of life in a great neighborhood. Did I forget to mention the savings on my electrical bills? Over a hundred dollars per month in the May-October timeframe! And not having to listen to the HVAC kick in so often! Kudos to Aimee, Director of Operations, for working so closely with her customers to meet their technical and budgetary needs and treating them like family members! Great company, great team! Thank you! Sheila

After receiving 3 bids for radiant type barriers, we settled on Green Energy. We are so glad we did. One company flat refused to do the job because the pitch was to steep, not these guys. Attention to detail was spot on, clean up after job was spotless. Everything from dealing with front office to job site crews was very professional, but managed to keep the "family feel" to this whole experience. Now all that would be a bunch of fluff except for the most important thing. My attic is 20-30 degrees cooler in just the first day, and they didn't finish the job until after 4 pm, and I'm writing this at 5pm.

Great windows. The install crew Dave, Richard and Mike were top notched. If I could give 10 stars I would. Windows blocked the road traffic next to my house.

In early 2018, I had Green Energy of San Antonio install Copperflect radiant energy barrier in my attic. I couldn't be happier. A little pricey perhaps but oh so satisfying if you want the best. Professional at every level, from first contact to installation to pics of the installation to follow-up contact. Some other testimonials claimed almost instant change in their energy bills. I was hopeful but skeptical since it is still winter. My wife and I are comfortable and I can tell our furnace is actually working less. I am actually looking forward to summer to see how much money I will be saving each month. Thank you Green Energy of San Antonio for such a great product that lives up to its hype.

Decided to redo all of our windows since our house was built in the 50's & still had the original ones. After calling around I choose Green Energy due to the reviews & website. The salesperson that came out was very nice & informative. I would suggest to anyone thinking of doing their windows. The company had the windows ready earlier than promised & installed all 6 in just a few hours. I've gotten many compliments on them and the house actually looks almost modern. The way they keep out sound & hot/cold is amazing. Definitely worth the money!!

Good quality windows at a fare price. Crew who installed the windows for the entire house did an excellent job. Left the job site clean, were fast and it was a full crew. Not just 2 guys. Fast service and the office staff is very helpful. Highly recommended! Just do it!

In Jan of 2017 Green Energy of SA gave me an estimate, to replace the windows, and a very large sliding glass door, in my house.They worked with me, until I found a solution that would best suit my home and pocketbook. They weren't the cheapest, and the installation did up running over by a couple of days, but it was worth it.Aimee did an excellent job of staying in touch, and keeping me informed. I was impressed enough with the work, and the windows, that I also had them install a heat barrier, and a ridge vent. My utilities have decreased, my house is quieter and safer. I've recommended them to others, and will continue to do so.

After extensive research on radiant barrier, we decided Green Energy of SA was the company for us. If given the opportunity, we always choose a family run business over a corporation. Their professionalism was spot on the entire process. Starting with the initial home visit for estimate from Steve to Aimee who was very personable and a joy to work with on scheduling, etc. Workmanship was top notch. The follow up inspection with Mr Ramos was our final interaction. Again, top notch customer service , very professional, and makes you feel like you've known each other for years. Can't wait to start seeing some lower utility bills!

Green Energy recently installed three new picture windows in our living area, overlooking the woods of the Silverhorn Golf Course. The windows are remarkably elegant and a tremendous upgrade to our home. The windows offer a tint that enhances the beauty of the outdoors viewed from the living space. We also added a new window in the bathroom that allows light, while maintaining privacy and air to circulate. We are very happy with the results. The installation process was carried out by David with a high degree of precision and skill. I would strongly recommend Green Energy to anyone interested in a professional and efficient window service that makes a distinctive upgrade to the home. Thank you for your service. I am looking forward to replacing more windows with your company over the next few months.

After doing extensive research and getting numerous quotes I am very delighted I went with Green Energy of SA. They showed up on time like they said they would, cleaned up after themselves and not to mention the savings I am seeing on my bill! Thank you for the best customer service and making my home cooler! I will be hiring them for my windows next!

Jymi Reyes is an incredibly knowledgeable person that treats his customers with care and respect. Always available for questions, doubts or clarifications. The radiant barrier installed in my attic along with a solar ventilation fan has been one of the best investments I have made! I recommend all my family and friends to get this done to their homes it really cut down my electric bill and my A/C people don't mind working in the attic to service the unit since it is much cooler up there. Thank you Jymi for a job well done by you and your team. I'll be calling you soon to replace my windows!

Green Energy of SA installed radiant barrier after we had another spray on type installed in our attic and the spray on type didn't work! What an amazing difference in comfort and savings on our CPS bills - our AC barely runs! My husband always says you get what you pay for ... you can pay a little more now for a good quality product that works, or you can keep spending money on your electricity and AC repairs over the long haul! Don't be fooled by companies with similar names ...they aren't using the same product and are profiting off the hard work and reputation of others.

We had windows installed by David and he was great! He walked us through each step and answered every question without hesitation. His team was quick and clean, and they always worked with our schedules. They were very sweet to our dogs. The windows look great and do exactly what Richard said they would. We've hardly had to turn on our AC or heat since getting them because the temperature in the house stays regulated better. We also had the radiant barrier installed in our upstairs attic which had made a huge difference in one bedroom that we could not regulate the temperature without an additional fan or cranking the heat way up. We are very happy with the results and wouldnt use any other window in the future!

My wife and I just had windows installed in our home. Green Energy delivered on their promise! Quality material, Professional installation, with great customer service. The installer David did an excellent job keeping us informed every step of the installation process. He was extremely courteous and professional and made sure that we were completely satisfied. We have more windows to install and you better believe we will be calling Green Energy back! HIGHLY Recommend!

I am truly impressed with the quality of service that we have received from Green Energy of San Antonio. I requested an estimate site survey and to get recommendations and they were at my house the next day. It was a pleasure meeting John Ramos, he was very knowledgeable and professional. He was also an excellent teacher. He shared a wealth of knowledge and expected nothing in return. The best part was when Mr. Ramos left the house we had a quote in hand and it was final quote no estimates, adding and making changes like other companies after the work is accomplished. It is a nice feeling to have the actual cost up front and not be surprise once the work is completed. The installation team was very courteous and they were fast. They arrived during the expected timeframe and they were out of there ahead of schedule.Within a few days after the installation of the radiant barrier, I already notice a difference with the heat level in my attic.Prior to payment an audit is conducted to verify the installation was successful and they checked the temperature levels in the attic. Prior to the installation the temperature was ranging from 120 and up. After the installation the levels were ranging from 85-95 degrees… wow what a difference. The temperature was matching the outside temperature levels.Since the installation I have received a CPS energy bill and it has gone down in price by $80.This has been a great investment.Thank you Green Energy of San Antonio!

I got the Copper Radiant Barrier. There were no savings. My home is STILL hot. When I complained, they came out and tried to sell me windows. The first evaluation showed our windows to be fine. 7 months later John Ramos offered me windows at cost. They will not refund the money and take back their material. John will laugh at you in your face as he tells you that you are the only disatisfied customer.

Last week, we had copper radiant barrier placed in both attic spaces of our home that was built in 1967. We had looked into solar panels as a way to be more energy efficient, but the overall cost was too much. We did some online research and thought radiant barrier might be a more cost effective alternative. I found Green Energy of SA online and submitted an online form for more information. I promptly received a phone call from Aimee, who was very friendly and informative. We scheduled an appointment for a free estimate and informative session. John Ramos, the consultant, showed up on time and was friendly and professional. First, he looked in both attics and did some measurements. Then, we sat down and he showed me the four types of radiant barriers they offer (sharing that they are the only local company to have copper barrier). He also showed video clips of their company performing temperature comparisons on local TV shows. It was very informative and by the end of the appointment, I felt I had a good grasp of the differences and benefits of each type of barrier. He left the estimate with me, so I could discuss it with my spouse. He gave us a call a few days later to check in, but was not pressuring us with a sale. We had decided we were going with the copper barrier that would offer a lifetime warranty. The price was very reasonable, and they offered us a discount, as well. They were able to schedule us within the next week. The day of the install, there was a small miscommunication. They had shown up to the wrong house, then left after trying to call our home phone (which we rarely use), so they actually got started a little later than expected. They had two teams working to finish up one attic, then moved to the other. They were professional throughout the entire install. They cleaned up after themselves, vacuuming insulation that had fallen out of the attic, etc. They were considerate of our home and were professional around our two daughters. They finished up the job before 4pm that day. At this point, we still had not paid a penny to the company. The next morning, John returned to the house for a post-install inspection. Everything looked good, and he told us we could expect anywhere from a 10% discount to a 35% discount on our CPS/ utility bill. It will take a little while for us to see a big difference, but we look forward to enjoying a more comfortable living space this summer-- hopefully with a lower bill. We'd definitely recommend Green Energy of SA to anyone looking into radiant barrier for their home.

Best company to deal with. Highly professional, prompt, friendly. They were on time (early) for my appointment. Within a few minutes John Ramos was like an old friend. We had the Copperflect Radiant Barrier installed, which came with a lifetime warranty. We also had an exterior wall filled with blow in. Their product is far superior to others on the market and their price was FANTASTIC!!!!! They will be coming back to do both window replacement and also Mom's house.....I WOULD HIGHLY RECOMMEND THIS COMPANY TO FAMILY FRIENDS AND NEIGHBORS...Thank you. Great Family owned company.

Two years ago we had the Copper Radiant Barrier installed in our attic. We live out in the country and have the sun beating down on our home most of the time. After the install it took awhile for the temps to stabilize in the attic, but after that - it has been wonderful!Before, we were always adjusting the thermostat to keep the house cool. All that did was keep our electric bills high and put extra work load on our AC. We set it at 75 and never touch it - UNLESS - we bump it up because it is too cool! Never thought we'd ever say that!NOW - in a couple of weeks we are having the Green Energy windows installed! We can't wait - and know that it will make our home even more energy efficient and give our home a beautiful new look!The icing on the cake - is the amazing service that GESA provides. From the estimates to the installs, this has to be one of the most professionally run businesses we have ever dealt with. From owner Richard Ramos - to installer Dave, from Aimee who handles all the transactions at the office and everyone else in between - YOU GUYS ROCK!May God continue to bless your amazing business so you can bless others,Steve and Sandy ObergNew Braunfels, TX

I had their new copper radiant barrier installed in my house. The installation crew were very professional and installed the product in less than a day. The sales process was no hassle and I know I have received more value than I paid. The proof is in the savings on my CPS bill. Thanks G.E. team!

All I have to say is WOW! I have had my barrier for over 2 years and I was concerned about reviewing the Barrier until I knew it was working. I love that my electric bill has gone down and my house is finally comfortable. I think I may need to call you soon for gutters. My wife is no longer a skeptic and now agrees it was money well spent!Thank you

This has got to be one of the most overpriced products i have ever seen. They quoted me around 7500 dollars to put there product in my attic. I think they are out of thier mind if they think that installing a insulation like material that will take 20 years to pay its self off in my attic is a good investment.
