5 Star Energy was great to work with and saved the client time and money with the Title 24 calculations and HERs testing. I look forward to working with them in the future and will be recommending them to others.

Friendly and helpful staff that really know what they're doing, trained in the ever evolving regulations of California's energy standards.

We are very pleased with the service, professionalism, and responsiveness of the staff at 5-Star Energy. We've experienced a range of very bad to very good subcontractors during our long-term new construction project in the Manton area and 5-Star is in the range of very good. You can absolutely count on them for their advice, expertise, quick implementation when adjustments are needed to energy calcs, and fast scheduling of inspections. These guys are really good at what they do.

Staff is very knowledgeable and friendly. Does what ever they can do to make sure that your new constructed house or building complies with California state laws and that it is energy efficient to save you money and help the environment.

As a home design professional, I have worked with the 5 Star team for over a decade and have found them far superior to other energy companies. Their attention to detail and professionalism is great and their turn-around time is incredible. Highly recommend them if you want to save money on your energy construction costs and have the permit and inspection process go smoothly.

5 Star was incredible. I got some permit review comments back that required some extensive energy studies. My engineering firm recommended 5 star for these studies and they did not disappoint. Within 5 mins of calling them Adrian and I had a plan together and within 24 hours I had the studies in my inbox. With how many delays I'm currently experiencing in the construction world it's nice to have a company go above and beyond. Highly recommend!
