Commercial Services


Service and Repair: We have vast experience with single site and multi site properties, single to multi story buildings, and single zone units to multi zone VAV/DDC systems. We work on units from 1 to 300 tons. No job too big or small!

Duct Leak Testing: You could be losing 35% – 40% of air through your duct system into unconditioned space. Thankfully, we have the equipment and training to find and repair leaks.

On-Site Service Technician: It can be very expensive to keep a full-time technician on your staff. Instead, we can provide you with a full or part time service technician without the expense.

Advanced Diagnostics (ACP): HVAC units are the largest consumer of energy and PG&E shows that most units are losing 40-50% of energy. We’ve have the equipment and expertise to help identify and reveal these inefficiencies. Exclusive access to Utility (PG&E) Energy Saving Program featuring a Free Air Conditioning Efficiency Analysis and if needed we can RETRO-COMMISSION your system – Some costs subsidized by California utility rate payers under the auspices of the CA Public Utilities Commission (CPUC).

Installation: We perform installations of all types of heating and air conditioning equipment; from single zone DX systems, multi zone VAV/DDC systems to the new highly efficient variable refrigerant flow multi zone heat pump systems that not only cut down on energy consumption and increase comfort but are also a great addition when used with PV solar.

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!
