Fast, honest heating and cooling help for Hayward homeowners from a family-owned team you can trust.
Hayward homeowners deal with a little bit of everything—warm inland days, cool evenings, and long seasons where your heating and cooling system needs to stay reliable. Whether you live near Downtown Hayward, Fairway Park, Southgate, Glen Eden, Jackson Triangle, Mission-Garin, or the Hayward Hills, we help keep your home comfortable with honest HVAC service and clear recommendations.
At California Heating & Cooling, we’re a family-owned company with more than 40 years of experience and over 100 combined years of hands-on knowledge on our team. We’ve served more than 10,000 customers, and we’re proud to be Diamond Certified with a 96% customer satisfaction rating. When you call us for HVAC service in Hayward, you’re getting a local team that knows how to diagnose problems correctly, explain your options, and do the job right.
We focus on residential HVAC services built around comfort, efficiency, and long-term value. Our team works on all major brands, including premium systems like Carrier Infinity and Lennox.
If your AC is blowing warm air, your furnace won’t start, or your system is making strange noises, we can help. We typically schedule service calls quickly, often for the next day, and in some cases earlier if you call early. Our technician will inspect the system, find the problem, and give you repair pricing on the spot.
There is a service and diagnostic fee for repair visits, but if you approve the repair, that fee is waived and applied toward the work. If the needed part is stocked on the van, we can often complete the repair on the same visit. If your system needs an OEM or special-order part, we’ll order it and schedule the return as soon as it arrives.
If your current system is older, unreliable, or costing too much to run, we offer free estimates for new system installation. We confirm equipment availability before quoting, so you get realistic options and no surprises. We install quality heating and air conditioning systems designed for your home size, comfort goals, and budget. Financing is also available.
Our team has experience installing top-tier equipment, and new system installs include a 10-year parts and labor warranty when annual maintenance is kept up. That gives Hayward homeowners real peace of mind.
Regular HVAC maintenance helps your system run better, last longer, and avoid costly breakdowns. It’s also required each year to keep the 10-year parts and labor warranty valid on qualifying new installations. Our maintenance agreements are designed to make that simple, with seasonal visits typically scheduled in the spring and fall.
We believe in honesty, transparency, and doing what’s best for the homeowner. That means no confusing sales talk—just practical advice, quality workmanship, and service you can feel good about.
If you need HVAC repair, AC replacement, furnace installation, heat pump service, or seasonal maintenance in Hayward, call California Heating & Cooling at (925) 492-7275 or send us a request through our website. We’d be glad to help you get your home comfortable again.

Real feedback on honest service, skilled HVAC work, and results that keep homes comfortable
“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.”
