Welcome to Valley Mechanical


Valley Mechanical is a full service heating, ventilation, and air conditioning (HVAC) contractor that’s been servicing the Bay Area since 1994. We have a specific focus on Indoor Air Quality, Energy Savings, and Comfort. Our goal is to provide practical solutions with measurable results while you benefit from a healthy, safe, and comfortable environment. This will save you energy, money, and most importantly, help reduce our carbon foot print from a global perspective.


Valley Mechanical is the best choice for commercial heating, ventilation, and air conditioning (HVAC) services. We offer fast, courteous and complete service for all our customers. We know that when you own or operate a commercial property, the functionality of the air conditioning is something that should go unnoticed, until it needs repairs! We’ve been servicing single site and multi story building, single zone units to multi zone systems in the Bay Area since 1994, including San Jose, Los Gatos, Sunnyvale, Santa Clara, and Cupertino.

Businesses depend on it, and your business depends on it. We are here to ensure the air conditioning in your buildings runs in a reliable and efficient manner. We’ll keep your air conditioning running as it should, but that’s not always good enough for us. We want to ensure that the building is energy efficient to keep your bills to the minimum. We have a passion for energy efficiency and we provide services to ensure your building is energy efficient. To achieve maximum energy efficiency we also have a program of retro-commissioning.

Our retro-commissioning program to help keep your bills down. Retro commissioning is when we analyze your cooling system, developing and executing a plan for fine tuning your air conditioning system for maximum savings. We test equipment and optimize all units, locating leaks in duct systems. Another thing we check for is moisture. Mold growing in a duct can be a quality of life issue and a health danger. We check for moisture and check for faulty sealants and replace them when necessary. When looking for a commercial air conditioning service, turn to Valley Mechanical.

Valley Mechanical Commercial HVAC Repair and Maintenance is proud to offer premium services, including duct testing and air conditioning repair.

Our Services



Our first contact with Valley Mechanical Corp. was a referral from PG&E, as a qualified service provider. We were inquiring about PG&E's hvac tune-up program. The service provided was outstanding, our units have never worked better and our tenant complaints and energy use have dropped drastically.

Below is a snippet of an email we sent:

"I know it was a little windy up there today but, you guys stuck it out and explained everything in a way that I can understand and communicate the essentials with others interested in the well-being of the building. I love the wifi based energy management system!!!"

"They were quick to respond"

We were really excited to get a new Nest thermostat. When our DIY installation did not go as smoothly as we hoped. we were put in touch with the folks at Valley Mechanical. They were quick to respond, were incredibly knowledgeable, and helped us to resolve the issue in a timely manner. Their service and office staff were helpful. professional and caring, and we are now very happy to have things working well with both our furnace and our Nest!

"They did a great job!"

"Juan and the rest of the team at Valley Mechanical did a great job! Our heat pump works well and pairs nicely with our new PV solar system. On their recommendation, they also installed an airscape whole-house fan that we used regularly in the summertime. They kept our house clean and well protected while performing their installation. In the process, we also regained a lot of floor space in our basement by keeping the unit off the ground."
