Great customer service! William and his team was responsive to text and phone calls quickly, took time to answer my questions and the install was fast/efficient. I have additional windows that I will e replacing and this is by far the best company to use for those

Highly recommend Efficient Energy Solutions to anyone who needs glass services. They removed and replaced two glass panels in a fast and timely manner. Stress free experience and couldn’t be happier with my new glass panels! Without a doubt will be contacting Bill for all future glass work. Thanks again!

EES has done a couple of jobs for me (air conditioning at my house and new window installation at my mother's house) Both jobs were done to my total satisfaction. EES's crews were very professional, showed up when promised and did a great job each time. They made sure I had the right HVAC unit for my house and discovered and took care of other issues related to the efficiency of the system to make sure the unit was running at optimal efficiency. I highly recommend EES!! You will not be disappointed!! 5 stars!

  • What should the customer know about your pricing (e.g., discounts, fees)?

    We have the lowest pricing & excellent financing available.

  • What is your typical process for working with a new customer?

    Start with asking what their goals are for the Project. Then answer as many questions as possible. At that point it will give me a good Idea of their expectations and develop pricing, Materials & type of installation for the Project.

  • What education and/or training do you have that relates to your work?

    I have 50 years of experience dating back to 1970 starting as a Glazier. Then over the Years I acquired the necessary experience to Obtain all the Correct State Contractor’s License’s to serve the Customers of the Greater Sacramento Area.
