Repair service with straightforward pricing
If your system is not working right, we start with a professional diagnostic visit. After we find the problem, we provide repair pricing on the spot. If you move forward with the repair, the diagnostic fee is waived and applied toward the work. When standard parts are available on the truck, we can often complete 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.
We service all major HVAC brands and we are experienced with top-tier equipment, not just basic models. That matters in Walnut Creek homes with advanced communicating systems, variable-speed equipment, heat pumps, or ductless mini-splits.
New HVAC installation built for long-term comfort
If it is time to replace your old furnace or air conditioner, we offer free estimates for new systems. We inspect the home, talk through your comfort goals, and confirm equipment availability before we quote the job. That helps us give you real options without wasting your time. Financing is available, and we install new systems as quickly as scheduling and inventory allow.
Our team installs quality equipment the right way so you get better comfort, energy efficiency, and system life. New system installs also include strong warranty protection: 10-year parts and labor coverage with required annual maintenance to keep the warranty valid.

“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.”
