About Us at Cencal Mechanical Heating & Air

Rooted in the Central Valley

Cencal Mechanical started as a humble group of HVAC specialists helping homeowners in Modesto, CA. Thanks to local support and our commitment to excellence, we’ve been able to expand our service area to offer HVAC expertise across most of the Central Valley.

Our vans are always stocked and ready to respond once you make the call. All Cencal Mechanical HVAC specialists are local employees who live in the same towns and neighborhoods as our customers.

Full-Service & Family-Owned

No matter how large we grow, our family-business principles will always be a part of the Cencal Mechanical way of doing things. We believe in honest quotes, guaranteeing our craftsmanship, and always treating our customers and staff with total respect.

Installing a heat pump or fixing an air conditioner isn’t a job for us—it’s the beginning of a relationship for lasting comfort.

//A Message from Our Owner at Cencal Mechanical

When I started in the HVAC industry nearly 30 years ago in Modesto, I never dreamed of expanding across Central California and helping so many people. It’s been an incredible journey growing our team and fleet and introducing homeowners to the latest HVAC technology.

I’ve always believed that being an excellent HVAC company is more than installing new equipment or fixing a broken air conditioner. It’s about educating homeowners on ways to improve their heating and cooling efficiency to lower their energy bills. It’s about preparing families for hot summers and cold winters with better HVAC equipment. And It’s about making sure our neighbors in the Central Valley are safe inside their homes.

I promise we will always be respectful and courteous, and always do our best to keep you comfortable in your home for the fairest price possible. More important than upgrading HVAC systems, are the relationships we’ve built over the years. And it’s been a blessing seeing the same people year after year.

I hope you trust our team to keep your home safe and that you choose us the next time you need some HVAC help. Because you deserve comfort.
