Sonoma County, CA

As many locals know, Sonoma County is home to a diverse range of unique microclimates. These variations can make climate control more difficult, but Ongaro & Sons technicians are up to the challenge. With our unparalleled local experience, we understand how to account for these differences and help you achieve long-lasting comfort. Whether we’re installing air conditioners in Cloverdale or furnaces in Petaluma, we always deliver top-notch results.

At Ongaro & Sons, we’re always seeking out new ways to serve our residential and commercial customers in Santa Rosa.

San Anselmo, CA

It’s been more than 80 years since Ernest V. Ongaro relocated his family business to San Anselmo. In that time, we’re honored to have served countless homes and businesses throughout the community.

We bring that wealth of experience to every new project we complete, ensuring we maintain the highest service and quality standards.
