"Atlas Home Energy Solutions is the real deal. Shannon did a thorough energy assessment and recommended several improvements. I was only able to do the top recommendation, air sealing/insulating the attic and whole house ventilation, but that made a huge difference! J.P., Vaughn, and a team of techs did the work in one (very hot) day. I noticed the difference immediately. Now the upstairs is much cooler on hot days and the a/c isn't running as long as before the work was done. The Atlas team is awesome! At the earliest opportunity, I will do more of the recommended items to make my house more energy efficient and comfortable and I suggest you do the same :)"

"Great! Job was complete .... removal of existing 50+ year old insulation, air sealing attic, baffle installation, installed 18 inches new fiberglass blown insulation, and new whole-house fan. Job started and completed as proposed. Crew on-time, quietly performed their work, and left spaces clean when done. Definitely worth the cost as noticeable improvement in second floor temperature and humidity readings."

"It was a pleasure again working with Yosuary Diaz and his team on our unfinished basement renovation. We hired them before for whole house interior painting. I would definitely hire him again for other home renovations. Him and his crew are great and are very skilled at what they do. Diaz was not the cheapest, but also not the most expensive contractor, but overall, well worth it! We had our entire basement gutted out and rebuilt. Diaz and his team rebuilt everything from the sub-flooring, new walls, and plumbing...and other major infrastructure that is not always thought of. We love our new basement with a complete bathroom! We highly recommend Yosuary Diaz and his team if you have a major home project."
