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.

Let me say professional, polite, clean, no rush, exceptionally competent, scheduling to meet your needs and ready to answer any questions as well as taking the time to explain things if your so inclined to want to learn more about your HVAC system. Those are some of the thoughts that come to mind when thinking about my experience with Certified Heating and Air Conditioning. It started in the office with Kim's very pleasant and service oriented personality in setting up and scheduling my job and ended in the field with Brittany and Jill, who's experience and work ethic resulted in a job well done. I would definitely recommend this company to all. Keep up the good work and God bless America.
