A New Chapter, Rooted in Science and Built for the Future
At the core of our company’s evolution is a commitment to growth, precision, and innovation. That next step began when the founder’s son officially stepped into the business, bringing a Bachelor’s degree in Physics with a strong foundation in Chemistry from San Jose State University.
This unique academic background combines deep technical knowledge with real-world problem-solving. With expertise in thermodynamics, system dynamics, and energy efficiency, he brings a fresh, analytical approach to HVAC, plumbing, and electrical work. His scientific mindset enhances every project—from smarter diagnostics to more efficient system designs.
By merging hands-on experience with scientific insight, we’re building a company that not only honors its legacy, but is also engineered for the future.
More about
our brand
Every great business starts with a story — and ours began in the trenches.
Before we ever had a logo, a truck, or a name on the side of a van, we were learning the ropes firsthand — working long hours as an HVAC technician, mastering the trade, and dreaming of building something bigger. What started as a job turned into a passion. And that passion grew into a vision: a company that puts quality, integrity, and people first.
From fixing our first AC unit as employees to launching A&B Heating and Air Conditioning from scratch, we've felt every high and low that comes with chasing something real. We’ve gone through the long nights, the tight budgets, the trial-and-error — and all of it shaped us into the trusted team we are today.
Now, with 10+ years in the industry, we’ve grown into a full-service HVAC, plumbing, and electrical company — proudly family-owned, bonded, and insured — known for doing things the right way, every time. Our clients aren’t just numbers on a schedule. They're neighbors, families, and business owners who deserve honest work from people who care.
We've walked the hard road to get here — and every step was worth it to earn your trust.
You’ll find us at 2081 Bering Dr R, San Jose, CA 95131 — right in the heart of Silicon Valley, where innovation never sleeps. Surrounded by some of the world’s leading tech giants, our location puts us at the center of progress, efficiency, and cutting-edge service. Whether you're looking for HVAC expertise, top-tier plumbing solutions, or reliable electrical work, we’re perfectly positioned to serve both residential and commercial clients throughout the Bay Area with speed, skill, and precision.
