Our Story

Family-owned HVAC,
done with care

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.
