Free In-Home Consultation
Sacramento's Energy Efficiency Specialists Since 1981
Enhancing homes with high-efficiency windows, siding, roofing, HVAC, and more.
Home Upgrades That Work Together
California Energy Consultant Service helps homeowners across Orangevale and the greater Sacramento area improve comfort, reduce energy costs, and make smarter upgrades for long-term efficiency. We provide window replacement, siding installation, HVAC replacement, AC repair, metal roofing, sliding glass doors, and other energy-efficient home improvement services designed to help your home perform better year-round.
Most contractors focus on one trade and move on. At CECS, we view your home as a connected system because your windows, roofing, siding, and HVAC all affect one another’s performance. Our Sales Consultants evaluate how these systems work together so your upgrades deliver real results, not just isolated improvements.
Why Sacramento Homeowners Trust CECS
Since 1981, California Energy Consultant Service has helped Northern California homeowners with high-quality, energy-efficient home improvements built on honesty, integrity, and lasting results.
Founded by Dick Lee, CECS was built on the idea that good work should lead to repeat business and referrals, and that remains true today. Our team is trained to view the home as a whole rather than treating each system in isolation, helping homeowners make better decisions about comfort, efficiency, and value.
We’ve been recognized as Window & Door Magazine’s “Dealer of the Year” for Most Innovative and named District 7 Small Business of the Month by Assembly Member Josh Hoover. With California contractor license #627677, a strong customer reputation, and a showroom in Orangevale, CECS remains a trusted name in home improvement throughout the Sacramento region.

Explore Our Services
Metal roofing is a CECS flagship offering, engineered for durability and performance. Residential standing seam steel reflects solar heat far more effectively than traditional shingles—a critical advantage during Sacramento’s intense summers. We partner with industry leaders such as CertainTeed and Taylor Metals and offer specialized aluminum roofing solutions for mobile homes.
Drafty windows are more than an eyesore; they drive up utility costs and force your HVAC to overwork. We specialize in full-window replacement with energy-efficient styles including double-hung, casement, bay, and specialty configurations. Featuring premium products from Milgard, Andersen, Simonton, and Anlin, we have the perfect fit for any regional home style.
Your siding is the first line of defense for your home’s thermal envelope. To ensure maximum efficiency, we offer high-performance fiber cement from James Hardie and LP SmartSide, along with selections from Westlake Royal. Whether you need a full transformation or targeted siding repairs, we ensure your home stays protected and beautiful.
High-performance patio and sliding glass doors are the perfect finishing touch to a window upgrade. Replacing dated doors alongside your windows ensures consistent energy efficiency and a cohesive aesthetic across your home. We’ll help you select a door that matches your style while significantly boosting your home’s comfort.
Even a perfectly insulated home requires a precision-tuned climate system. From AC repair and full system replacement to ductless mini-split installation, we ensure your heating and cooling work in harmony with your home's other efficiency upgrades. Keep your system running at peak performance with our professional tune-ups.
Stop guessing where your energy dollars are going. Our Home Energy Audit pinpoints exactly where your house is losing air or failing to insulate. Whether the fix is air sealing, ductwork, or equipment upgrades, our performance assessment provides the data you need to prioritize the right improvements first.

What Our Customers Say About Us
We couldn't be more pleased with our new roof! Sam, John and Oscar did an amazing job!! They were prompt, thorough, and did a great job of communicating. We highly recommend them.
California Energy Consultant Service did a fantastic job. To start, Gary provided us with a quote and he was efficient, friendly, and knowledgeable. He came out very quickly and was able to answer all of our questions. Furthermore, once we signed our contract, we were able to schedule service within 2 weeks. The crew who completed our service was on time and prompt. Alonso, Omar, and Oscar were friendly and worked hard. Our windows look amazing! Thank you, California Energy Consultant Service. We love our new windows!
Once again this wonderful company made our day. Our 21yr old AC stopped working on a hot Friday afternoon in July. It was after hours so I texted, and left a voice mail, hoping to get on their schedule soon. Monday morning I talked with a lovely representative who scheduled us for 12:00 to 2:00 that very day! Jason actually was able to come early, at 10:30. He did a thorough review, and replaced the capacitor at a very reasonable price. He also discussed maintenance items with my husband. This is absolutely the best local company around. Jason was another great employee to interact with.
I had three small metal framed windows in an adobe building that needed replacing. Three quotes later, we selected California Energy Consultant Service. They gave us a great price and quick scheduling. Omar and Alonzo showed up on time and completed the task in short order. The final product looks great! I will be very happy to do business with these folks again!
