California Energy Consultant Service

Incredible! CECS replaced ALL the windows in our duplex, one side in 2021 and the other just now in 2024 (24 windows total). Not only do they work beautifully and look amazing but the team was done by 2pm! Alonso, Omar, Jose, and Turbo were a delight. They were friendly, considerate, and kept our place very clean. Couldn't recommend this company more, thank you! Luke, Liz, Shea

California Energy Consultant Service installed new insulation and ductwork, after which the bathroom exhaust fan was not effectively clearing condensation. After investigating the problem, which showed they were not at fault, CECS will be replacing the fan. They have shown they will do what is needed to ensure quality work and customer satisfaction.

After consulting numerous companies we purchased new windows and patio doors from California Energy Consultant Services for our 1987 home. We now have more light in the house, less noise from traffic and passing trains, and enjoy a clear view of our yards. The neighbors have complimented our home's new "look." John Frook was knowledgeable, accesible and answered all of our questions. Alonso and Omar expertly installed the windows and doors and took away the old materials. They were the neatest contractors we've ever had! We highly recommend CECS for replacement windows.

We had the most wonderful experience with California energy consultant services! Our heat went out on Saturday and by Thursday we had a brand new heating and air-conditioning unit installed by James and Mitch. They did such a wonderful job and are such hard workers They even wiped down dust, and did a vacuumed after the job was done! We could not be more happy with our unit that works amazing and even the house smells fresh and works efficient! Customer service was amazing and I was able to get all of my questions answered. You can tell they have a great employees.

I am very happy with Gary, sales manager, Mitch HVAC technician, Ismar/Turbo and Jose window installers. They rock!!! Gary is such a wonderful person and sales manager. He never gives you any pressure to hire his Company. He is like your friend who likes to talk about usual things. lol Thats why I hired his company to replace about 28 windows and sliding doors in my previous house. They did such a great job!! So I hired this company again to replace all my windows for my new but smaller house. Ismar/Turbo and Jose did such a great job with installation and cleaning up the mess. Ismar is a people person. Very pleasant and easy to work with. Jose is quiet but he is also pleasant and easy to work with! I appreciate their excellent work ethic and pleasant manner!! Mitch is HVAC technician who also did such a great job checking my heater and airconditioning system very thoroughly and explaining everything to me. He even wanted to replace my air filter but I didnt have a new one. He helped me to buy a much better quality air filter at Amazon. I appreciate his excellent service and pleasant manner as well!! I am going to recommend your company to all my neighbors!!
