HVAC contractor serving Concord, CA since 2018

Ces Tech Heating and Cooling is a locally owned, family-run HVAC company based in Concord, CA. We serve homeowners, business owners, and property managers across Contra Costa County, Solano County, Alameda County, and Santa Clara County. Our roots are in this region, and so is our commitment to the people who live and work here.

Before founding Ces Tech in 2018, our lead technician spent years working as a subcontractor in the HVAC trade. That hands-on experience across residential and commercial jobs built a deep understanding of what customers actually need: honest assessments, reliable work, and a team that shows up when they say they will.

We handle the full range of HVAC services. Whether you need a repair on a residential system, a new commercial installation, routine maintenance, or duct cleaning, we have the equipment and experience to get the job done right. We also provide commercial refrigeration services for businesses that depend on temperature-controlled environments.

Being a family business means we treat every job like it reflects on us personally, because it does. We are not a large franchise with rotating crews. When you call Ces Tech, you get a consistent team that takes pride in clean work and clear communication.

We are available Monday through Saturday, 7 AM to 7 PM, so you are not stuck waiting until Monday to get help with a heating or cooling problem. Our service area covers four counties across the Bay Area and surrounding region, and we are familiar with the climate demands and building types found throughout these communities.

If your system needs attention or you are planning an upgrade, we are ready to help. Call us at (925) 339-5537 or email us at Cestech.coolheat@outlook.com to schedule service or get answers to your questions.
