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.
Response from Certified Heating and Air Conditioning:
Hi Justin, Thank you for the 5-star review! We love that you are happy with our install team, the installation of your new heat pump system, and our advisor Luis! Welcome to our Certified family. - Certified Customer Care Team

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.
Great service

Today certified solar was in the Vallejo area performing a king valve change out under warranty. We braised in new valve, tested with nitrogen and ensured that pressures reached manufacturing specifications. With the issues being fixed, the clients will now be ready for this hot summer that’s due to us.

I completed a maintenance for a heat pump in Vallejo for my client, Jasmine. I was happy to see that the fan in air handler was very clean! 😀

In the Vallejo California area performing a furnace diagnostic! This 11 these old York furnace would not start! After inspecting, we detected that water was leaking right on to the flame sensor! 😮 if the flame sensor can’t sense flame, then we have no fire! After cleaning and making the necessary repairs, this unit is running properly! I am in the Heather ridge neighborhood a lot! Let us know if we can assist!

Diagnosing a zoning issue at a home on Mare Island near Vallejo, CA. We replaced some dampers at this home a few months ago and one of them isn’t working correctly. After inspecting the system noticed that the set screw was not tightened and was allowing the shaft to spin further than it was supposed to which caused the damper to open so much that it closed. Got it all fixed up and now the zoning is working fantastically! Thank you for choosing Certified Heating & Air Conditioning!
