California Energy Consultant Service

We have been working with CECS since they installed our windows/doors in 2003 and then again in 2012 for the remainder of our home. We have found them to be professional, efficient, have excellent workmanship and quality, accommodating, and friendly :). We immediately noticed that our home was cooler in the summer and warmer in winter, thus keeping our energy bills down. Recently they had to replace the screen on a sliding door, add a pet grate, and replace the slider lock because of our anxious puppy...we so appreciate Lisa's help and CECS staff assisting us with this! :)

CECS just finished a small job for us as part of a kitchen renovation. They removed a sliding door, and replaced it with a window, so we could extend a countertop along the wall. They were always prompt and courteous. Even though there were a few hiccups (finding the right siding) they worked through them, and when the job was finished, it was exactly what we wanted. Their workers were professional, paid attention to detail, and cleaned up after themselves. We highly recommend California Energy Consultant Services.

As a contractor I have been purchasing windows from this company for 12 years now and they are the best! They always deliver!

Once we got the ball rolling on the projects Cal Energy was going to do to our home, everything was great and we have been happily living with upgraded windows/sliders, attic insulation and new duct work for the furnace/AC over the last year. My wife and I are so happy we got these projects done. They even assisted in lining up PG&E rebates. Best thing we decided to do since buying our home is do work with Cal Energy. Working with Lance (sales) and Kristen (billing) was a pleasure. Recommended to many of my colleagues and friends.

I used Cal Energy for my windows on my duplex 10 years ago so when it was time to replace my HVAC I gave them a call. I learned that SMUD was offering amazing rebates for HVAC, insulation, water heaters and electrical panels and that I could get most of the rebates for both sides of my duplex. Of course this sounds too good to be true, but it was absolutely true. I hired CECS to do the complete package switching over to all electric and upgrading the electrical panels on both sides of my 60 year old duplex. Jamie the manager of the department reached out to me to go over all the details and how the project would flow, and we set a schedule. All the workers and installers ( Jason, John, Joe, Johnny and Cody ) were very efficient, friendly, and all and all great to work with. CECS even took care of all the paperwork for the SMUD rebates. I couldn't be happier with them as a company and would recommend them to any one looking to do a HVAC or home performance project.

Very competitive pricing and our experience with the very professional team was excellent from start to finish ! I have already recommended my friends.

I went to CECS to see if I could find a replacement part for a lock on my patio slider. I spoke to Jamie and she said they did not carry the line. But here is the awesome part, she knew the line and that a friend of hers works there and asked for his help. She kept the lock, took pics reached out and a couple of days later handed me a brand new replacement part. This is amazing customer service, she could have easily left it at we do not carry that line. She went above and beyond, this in itself is a fantastic reason to think that they will give you the service you deserve. Thank you CECS. Thank you Jamie. I am happy, my wife is happy and my slider locks again. :0)

I love my whole house fan! PrIor to installation, I was concerned about my indoor air quality because I have allergies. I was also aware my electric bill would be climbing high in summer with the rate increase. I have actually noticed a reduction in my allergy symptoms, reduction in my electric bills, and NO extra dust in my house that people thought I would have. The cool air helps me sleep better at night too. It’s nice coming home to a cool home after work when it has been a triple-digit day! Jim is very knowledgeable about energy saving measures and explains thoroughly the best options for equipment for your home. Thank you!

Excellent products, fast easy consulting, perfect installation, outstanding pricing!

Salesman named Gary had a bad attitude and completely overcharged my grandmother. Stay away.
