Energy Core was a pleasure to work with from the initial call to the follow-up after installation. When their sales rep first called to introduce me to their company, they were polite and considerate. I normally hang up on solicitors but they were very friendly and did not pressure me into listening to them. When their sales rep came out, he was eager to talk about the job but also about us as people. The process went smoothly and the install was so efficient. We had 13 windows and they finished in one day. They were so considerate and cleaned up well afterwards. They even had a follow up appointment to make sure everything was good! Love their company!

I am very pleased with EnergyCore Construction from the quality of their product to their incredible customer service. The windows I had them install have lowered the noise from the street, stabilized the indoor temperature and they look beautiful! Zach explained everything from the cost, to the functioning of the windows, to how they would be installed. When Taylor came to measure the windows he explained again how the installation would proceed. Everything went exactly how it was explained to me except it went faster than the timeframe estimated. The crew installing the windows were extremely pleasant and left my property cleaner and better than when they arrived. This experience has been a win, win, win!

I'm very pleased with my new windows!! Eric helped me out and made it affordable for my budget. He was very informative and not pushy like a lot of the other companies that came out. They look fantastic and the install went really well. Overall 10/10 experience would definitely recommend Energy Core for home upgrades.

German was amazing with both knowledge of the product and compassion for my situation. He went above and beyond to make sure everything went smoothly. The team showed up and in a blink of my eyes I had beautiful windows that are energy efficient. I thank he and the team for making my home beautiful.

Recently, we decided to repaint our house and allowed for Energy Core to be the ones to do it. We had never used their services before, so it was quite worrisome. However, they exceeded expectations, the coloring is nice, well painted, and just how we had asked. The people doing the job were incredible, they were professional, and would ask questions regarding the painting! They were great at their work, and overall, very pleasant workers! If we were to hire anyone to paint our house again, it would be Energy Core! Thanks!

I recently had all the windows in our home replaced by EnergyCore Construction, and I couldn’t be happier with the entire process. From the first meeting with their associate, who was incredibly professional and a great communicator, we felt like our needs were heard. They didn’t try to oversell us, which we really appreciated. The measurements were taken quickly, and to our surprise, the windows arrived much earlier than expected. The installation team was efficient, professional, and fast. Now, I find myself walking the dogs just to admire how our house looks! Beyond aesthetics, the house feels more secure, cools down quickly, and stays cool for longer periods. I’m really looking forward to winter, knowing it’s going to be so much more comfortable inside. Highly recommend EnergyCore Construction for their excellent service!

Happy with my window install. Nice quality windows, they make a huge difference with temperature and noise in my home Quick process and easy process.Only complaint, about a week after my project was completed I had salesman blowing up my phone with the "next best offer" to work on my home. He calling my phone 3-4 times back to back when I was unable to answer.Overall we had a good experience.

We have used EnergyCore twice now. First for our roof replacement. Second time we just had all the windows in our house replaced. Two huge bay windows and the sliding glass door. They’ve been great! Jared our project manager is awesome! Great customer service and very responsive to our needs and questions. I’ve included a few pictures. I highly recommend their services.

We recently had Energy Core Construction replace our old aluminum-frame windows. The Anlin windows are far superior to in their construction and offer many great features. The installation crew worked very well together, arrived on time and finished ahead of schedule. We're very happy with the final product and recommend this top-notch company highly!!

We had our windows replaced a few weeks ago, and it’s been one of the best investments we’ve make into our home! The entire process from start to finish has been so smooth, and positive. Johnny came out to explain the products to us and make sure we completely understood all of the information to us, as well as the cost and who to reach out to in case we had more questions or any issues. The crew that came out to install the windows was very professional, clean and respectful of my home. They finished quickly, explained how to use our new windows thoroughly and they left my home just as clean as before they began working. I really appreciate Johnny & the entire team for making our window installation process a great one!We are completely satisfied and glad we made the upgrade. We live on a very busy corner, luckily the noise has been greatly reduced since having the windows! We also find that we are not having to keep our AC on all hours of the day/night because the house is staying at a comfortable temperature. We used to have bars on our windows (they were installed by the previous owners, and I hated them lol) and the team was able to remove those and we feel very safe with the locks on our windows without the bars now. Our home looks much better with the new windows.Zero regrets! Great investment! Awesome team! Thank you!

It was a pleasure working with Landis. He was very informative when purchasing our new windows, answered all of our questions. The window were recently installed (within the estimated time frame we were given) and they look great. All 8 windows were installed and everything cleaned up in about 5 hours. I was pleasantly surprised it was so quick. Definitely feel a difference in the house, and the windows are not hot even when the sub is beating on them. We love them. Great windows.

15:36 16 Jun 23

Amazing experience overall! Zack was extremely professional and helped me with the process. The windows themselves look amazing had 7 windows installed, house looks much better. It’s definitely cooler inside and they block out so much outside noise I couldn’t be happier with what I got!

16:08 03 Jun 23

My family and I were very impressed and grateful for the service we received from Energy Core Construction. They installed beautiful windows and doors that are both energy efficient and affordable. My house instantly got a facelift. Johnny was an excellent representative, and he made sure the process was seamless from start to finish. I can’t thank you enough!

Thank you Energy Core Construction. I would rate you guys at 10 if I could. Everyone that was a part of this project was really professional and respectful. They finished everything on two days. We got new ducts installed with a furnace with a new HVAC system. We love how it looks. Mike and Spencer were super awesome. I would totally recommend. Everything they say they would do they went beyond amazing company.

18:40 11 Jan 23

I love our new Anlin windows. I have lived here for about 20 years. We had the original windows. The biggest difference I can see is the installation. I love how warm it keeps my house during the cold months and it’s the house nice and cool during the summer. Spencer is an amazing job. I would totally recommend energy core construction. They finished everything in one day. The trash was left behind. They exceeded our expectations.

We installed 7 Energy Core Construction windows in the house in early spring 2022. About 9 months have passed since then and now we can confidently say that our choice of the company ECC was absolutely correct. The windows are great. They perfectly keep the temperature and significantly reduce the external noise in the house. Easy and convenient to maintain. Great job. Thank you very much.

03:29 15 Nov 22

This review is being done about 2 years after our windows have been replaced. We are extremely pleased with the quality and performance of the product. The noise is reduced. We see a difference in the temperature inside our home which helps with our cooling costs. We greatly appreciate the work and company.

21:37 29 Sep 22

We had the anlin windows installed on our home! Dean the representative was great, he helped us get the windows started. Installers were very good and cleaned up. Very good pricing and quality. Overall great experience.

20:41 25 Aug 22

We would highly recommend energycore construction for windows. Zack was very helpful and Kenny helped us as well. The windows operate very smoothly and definitely make a big difference in keeping the heat out. Great price.Great company..

Got windows installed on my house and after the installation I noticed that standing near the windows I didn't feel the heat from outside like old windows. The noise has been significantly quite and the house stays cooler even with out having the ac running constantly. Dealing with energy core was also very easy since they kepted us updated on what was going on and when the installation will be started.

21:15 02 Aug 22

The Team was quick and did great work - the Windows look wonderful and keep the house at a nice consistent temperature

20:10 02 Aug 22

They were excellent. On time friendly did exactly what we wanted and what they said they would do. Great communication and follow up. Would definitely recommend.

This is quite a different review, so this company brought me in for an interview for a job opening as a home improvement salesperson. Tobias was very professional during the interview and all interactions I've had with this company were very professional and respectful. Unfortunately, life can be rough sometimes and I had to turn it down last minute which was a huge bummer. All I can say is this is a great company (the reviews speak for themselves) and I just want to thank you Tobias personally and I apologize the way things turned out and me not being able to take the job, I also want to thank I believe his name was Eric for being very professional aswell. Lastly, this company only offers the best quality services and the best quality products for there customers.

20:09 10 May 22

Energy core service was excellent, we replaced all our windows and the quality is great. They were fast, efficient and clean when installing.

I loved the windows and our sliders. I would recommend energy core once again. Rafael was a great help with job walk. Zach Mckay did a great job with the demo. This company really does great work.

02:30 26 Feb 22

We had 7 energy windows installed. Love them. House looks beautiful and don’t have to worry about that High Desert dirt and dust in the windows. Was thinking about the patio doors but I have bars. Thanks Tobias maybe next time Great Job.

We had windows and a sliding door installed on our home. Looks great. Operation on the anlin windows are smooth. We had a security latch issue and we called company about it. They we very responsive and we’re out here within a short time and resolved the matter. Good value and Price. Zach was very respectful amd professional.

We had sliding doors and high quality paint job done on our home. Paint was done very very well and professional. Prep work was very great. The sliders are anlin windows and extremely satisfied. The reason for our 4 star review is the painters left stucco debri in back of house so clean up could have been better. Overall very satisfied with value and work.
