HVAC Construction


Legacy delivers engineering design and installation with an eye on long term energy efficiency and extending the useful service life of equipment. This is a reflection of one of our core beliefs - that energy and cost savings can be achieved by involvement in the complete life cycle of the building’s infrastructure.


In the fast pace of business in the Bay Area and Silicon Valley, Legacy has distinguished itself by providing a rapid response approach to our Tenant Improvement offering. We understand the needs of the real estate community and tenants who need to have their space designed, built, commissioned, and turned over on a fast-track basis.

Under the leadership of a Vice President, Legacy takes a very personal approach to serve these clients based on trust, technical expertise, communications, and keeping our promises.  

This relationship-based philosophy is evidenced by our robust portfolio of projects delivered for repeat clients. When it comes to scope, Legacy is equipped with a talented project management team experienced in all sizes of projects. Whether it’s a simple commercial office duct relocate or a complete building system mechanical rework, Legacy is capable of taking it on.


Our qualified engineering team enables Legacy to take on any Design Build project. Legacy Professional Engineering Team has broad expertise, knowledge, and experience on all types of HVAC systems, of any facility size.  We keep abreast of the latest Building Codes and California Title 24 requirements to ensure that our clients receive a fully code compliant and complete project. Additionally, our engineering team is exceptional at streamlining the permitting processes of all Bay Area cities, making sure projects are delivered on time.


Some of the most challenging projects handled by the Legacy SPTI Department are the upgrade and replacement of central system equipment such as large chillers, boilers, and cooling towers. Whether this involves a helicopter lift of a 600-ton cooling tower on a 20-story building, or easing a 400-ton chiller through a temporary opening in a building with just one-half inch clearance on each side, Legacy is skilled in the pre-planning, organization, safety, and execution of this work. Our SPTI installation teams stand tall in the HVAC world and are consistently praised for their performance by customers, general contractors, and consulting engineers.


The EPA estimates that as buildings age and occupancy changes, there is likely  a 17-20% energy savings opportunity through a retro-commissioning project.. This approach returns the mechanical and control systems to their original design specifications and restore optimal performance. .The retro commissioning process will also reveal additional opportunities for optimizing a facility’s performance.
