Vallejo is a waterfront city in Solano County, located in the North Bay subregion of the Bay Area. It is geographically close to East Bay and sometimes associated with that area. Vallejo has a mild, coastal Mediterranean climate and can be an average of 10 °F (6 °C) cooler than nearby inland cities. Vallejo is influenced by its position on the northeastern shore of San Pablo Bay, but is less sheltered from heatwaves than areas directly on or nearer the Pacific Ocean/Golden Gate such as San Francisco and Oakland. The hot summer months usually run July through September.

Justin - Vallejo, CA 94590
Chris, Nicholas, and Wyatt were extremely professional, knowledgeable, and efficient. They installed a heat pump for our HVAC needs. Completed in one day, I couldn't believe how fast it was. Luis who gave me the bid and quarterbacked the install was my point of contact for the whole process and made this whole process run smoothly. Overall my wife and I will be calling Certified Solar, Heating & Air Conditioning again for any future projects.
