Heating & AC Repair in Vallejo

Alfred Zampa Memorial Bridge at Dawn

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.
