The service technician, Steve, was incredibly knowledgeable and considerate when answering my questions about installing our awning window. Steve’s availability and experience were so valuable to me. He went above and beyond to give thorough explanations!
EnerLux has the best customer service! We built a brand new custom home a few years ago and out of all of the contractors and companies involved in the process, EnerLux shines above the rest. I would never hesitate using EnerLux again for future projects. Thank you for your customer care and support.
I love my Enerlux windows. Just built a house and did lot’s of research before deciding on Enerlux. Even visited the factory.

I love my Enerlux windows. Just built a house and did lot’s of research before deciding on Enerlux. Even visited the factory. The windows are solid, quiet, look amazing and should outlast other brands. There’s no equal to the materials and construction-fiberglass frames, thicker glass, reinforced corners and upgraded hardware. Working with the staff was a pleasure. Small company with real people-no automated phone routing games. Anytime I had a question or issue, someone got back to me and made sure it was taken care of. No need to look at other brands-they can’t compare to Enerlux! Thank you to the Enerlux team!
We used EnerLux windows in our house and had some issues that were addressed and resolved by the Enerlux team. I can say honestly, they have better customer service than almost any company or contractor I've ever dealt with. The owner got personally involved and continued to follow up over a long period of time until the issue was completely resolved. He was relentless in a commitment to ensuring we were happy with the end result and went far out of his way to make sure. It was incredibly refreshing to see that, especially in this era where the consumer is usually left in a black hole of communications or customer service if anything goes south. I would highly recommend them as a company.
I'm a year past install and our whole house window replacement project is still strongly intact. Looks like there's a reason everyone who purchased Enerlux all have given 5 stars, they're really that good. I did way too much research on all the materials and companies. I considered Marvin, Pella, Anlin and many other companies. I almost lost my install contractor with so many questions. The end result is truly awesome. Enerlux creates the best windows for large openings. Foam filled for maximum efficiency. You'll pay more for fiberglass than vinyl, but for fiberglass they’re the best value and you're doing the best thing for the house & environment. We installed a variety of awning, casement & picture windows. Enerlux even built a combo awning/casement because we needed a bedroom egress, but wanted the other side to block rain in case we left it open at night or while away. Truly awesome. Also great to support made in USA.
Hello! We really appreciate your comments and so glad you love the windows! Please reach out if you need anything. Sincerely, John Moylan

Hello Mannie, Thank you so much for the review and the kind words about our staff! So glad you love our windows! Sincerely, John Moylan
My Enerlux experience has been fantastic! From Jim the salesman to Angela and Lisa and everyone in the office. To Mike and Danny who painstakingly packed our windows on the truck we brought to the factory. To Zach the installer who patiently walked me through my installation questions and concerns. I'm only about halfway through my installs, but they're going great thanks to the Enerlux team!
We chose Enerlux windows for the performance, ease of maintenance and cost and are extremely happy with all three. The triple pane windows perform amazingly well in our mountain home. Additionally on windy days it is quiet as can be inside and the screens are a piece of cake to install and remove for cleaning. very satisfied with the windows, doors, and service we have received from Enerlux
We love our windows from Enerlux. The look and quality is amazing. I am very glad we chose them over the other options presented to us when we built our house. The customer service from everyone at Enerlux was great as well. Everyone we dealt with was pleasant to work with and they went above and beyond our expectations.
Just had another round of windows replaced with Enerlux windows installed by Tevelde And Co. in the Omaha, NE area. The first round we went with the double pane casements and fixed windows and was impressed with the overall quality, the ease to open/close the windows, double latch locking mechanism, flex screen that is barely noticeable, and ability to clean the outside from inside for our 2nd story windows. I was a little hesitant going with Enerlux as they weren't one of the big-name window brands I was originally looking at, but comparing spec to spec and price I took the leap and wasn’t disappointed. For this last round we went with the triple pane, LoE 366 glass with a grey tint. I couldn’t be happier with the reduction in sound and not getting baked by the sun sitting next to my windows, even compared to my old windows that I installed a solar tint to. Todd and team with Tevelde And Co. did another awesome job installing these large 6 ft windows and making sure I was happy with the tint options by getting samples before finalizing the order. Only regret was not going with the triple pane for the front of house, but certainly will for the next round in our bedrooms.
We truly appreciate your willingness to go out of your way to write a review and are so happy you like our windows! Thank you for trusting EnerLux Windows & Doors! The EnerLux Team
