Fast, honest heating and cooling help for local homeowners who need reliable comfort and clear next steps.
Vallejo homes deal with a little of everything: warm summer days, chilly winter mornings, bay air, and older homes with different heating and cooling needs. We know homeowners here need an HVAC company that shows up, explains the problem clearly, and fixes it the right way. That is exactly how we work at California Heating & Cooling.
As a family-owned company, we focus on honest service and real solutions. Our team brings more than 100 years of combined experience, and we have served over 10,000 customers across the region. If you need HVAC service in Vallejo, we are ready to help with repairs, new system installs, and ongoing maintenance for long-term comfort.
Whether you are near Glen Cove, East Vallejo, Hiddenbrooke, Mare Island, or Central Vallejo, we provide residential HVAC service designed around your home and your budget. We work on all major brands, including premium systems like Carrier Infinity and Lennox, and we also service heat pumps and mini-split systems.
When your furnace stops heating or your AC cannot keep up, we do not believe in guesswork. We inspect the system, find the issue, and give you straightforward repair options on the spot.
We keep things simple. For HVAC repair, we schedule your visit, diagnose the problem, and provide repair pricing during the appointment. If you approve the repair, the diagnostic fee is waived and applied toward the work. If the part is stocked on the truck, we can often finish the repair on the same visit. If your system needs an OEM or special-order part, we order it and schedule the return as soon as it arrives.
For new HVAC installation in Vallejo, we offer free estimates. We confirm equipment availability before we quote, so you get clear options without surprises. Financing is also available, which helps many homeowners move forward with a replacement when the time is right.
A good HVAC system should do more than turn on and off. It should keep your home comfortable, control energy costs, and run reliably through the hottest and coldest days of the year. That is why we take time to recommend the right repair or replacement based on your home, your existing equipment, and your goals.
If your current system is older, struggles to keep up, or needs frequent repairs, we can help you compare options for a new high-efficiency system. We install quality equipment and back new systems with a 10-year parts and labor warranty, as long as yearly maintenance is kept up.

Reviews
Real feedback on fast repairs, fair service, and heating and cooling work done right
“une 19, 2026, I contacted a company California Heating and Cooling by phone and requestes specifically for Mario. I selected him since his name was mantioned in many reviews, as an excellent expert. Mario came the next day, in the morning. At the end, Indeed, I was not disapponed. Opposite, I was thrilled. Mario performed real checking of the whole cooling system including a compressor.. Mario localized mulfuction's parts and then exchaned them accordingly. Mario was very professinalanal, confident and knoweledge in electrical problems of the coolng system. The most important, he restored the whole system and make it to work again, the same day, in a few hours. I was impressed. Other consultants suggesed to exchang the whole system i.e. a furnace and a cooling system that usually costs from 21K to 28K. Others suggested to verify only a wiring system that is stil expensive ($750). I have mine system repaired for less. Therefore, Mario and also Mark, (even Mario admitted that Mark is very good in his profession) are persons whom you may trust. Mark was a second person to whom many reviewers reffered. Thanks to earlier reviewers for their honest evaluation of work performed and providing names of persons involved. It helped me a lot to in selecting a proper person. God beless all of you. Helena M-B.”
