"The work was done professionally and done on schedule. Raymond the manager gave me all the information I needed before the start of the project . The communication was timely and valuable throughout the project. The main reason I hired Excellent Electric is because Raymond also made recommendations that help to reduce the cost of materials and labor. I interviewed three other companies and all gave me competitive prices, but the recommendations Raymond gave me, set Excellent Electric above the three other companies I interviewed. I will hire Excellent Electric again and recommend this company."

"Besides Solar work that they completed at my house, CEB also installed 2 ceiling fans inside house, and removed all interior carpet and put 2'x2' Travertine ties w the thinset & grout, and painted the entire interior of house. They took care of the project clean-up as if it were their house. I researched what CEB can do, and with their Class "B" Contractor license they can build a house from the ground up, and do Home Improvement projects, and pull any required permits from the City. These guys are legit. You will be a satisfied customer working with California Energy Builders."

"We purchased the home energy audit with the understanding that we would be receiving a more extensive analysis of our home energy usage along with possible solutions. Ultimately, the process was more about a presentation for solar panels that anything else, which was not what we were looking for when we purchased the offer. Richard was very professional and thorough in his presentation and presented options regarding areas to save in terms of energy usage but those areas were not as thoroughly explored as the solar discussion. Green Source Energy should be more direct about what the Home Energy Audit entails so buyers can make an informed decision."

Energy Efficiency Auditing questions, answered by experts

Wood windows fall in the middle of the window frame materials when it comes to energy efficiency. They’re more insulating than aluminum and vinyl, but they aren’t as efficient as fiberglass or composite frames. If you love the look and lifespan of wood windows and want to maximize efficiency, you can upgrade to double-pane or triple-pane glass and consider window tinting and low-emissivity (low-E) coatings to minimize heat transfer.
