“H&G Systems has installed the mechanical systems on several of our projects over the years, and we’ve always had a great experience with their team. The projects have included a variety of different facilities, ranging from a multi-purpose recreational facility (the Brook Hollow Golf Club renovation); the renovation of a downtown high rise office (One Dallas Center – home of HKS); the renovation of a historical local church (Highland Park United Methodist Church); and a multi-phase greenfield project (First United Methodist Church – Richardson). Our firm has appreciated their focus on quality, and we look forward to teaming with them again in the future.”

“EMA’s first experience with H&G Systems was the construction of the natatorium for Mansfield ISD. We quickly learned to appreciate the H&G team’s dedication to the complete success of the project. It was refreshing to have H&G there to assist the design team as well as all members of the construction team so that we could all turn over a well built and functional building to the owner. Since the Mansfield natatorium EMA has had several other similar construction experiences with H&G Systems, mostly in the natatorium market. I have also come to personally know several of their team leaders. The strength of their personal character and principled morals reflect in their business model and is the obvious key to their success. EMA looks forward to every project that involves partnership with H&G systems.”

“H&G Systems has been one of our most trusted specialty contracting partners for over twenty years. It’s common for us to involve them in the projects that require our HVAC and plumbing partners to team up with the MEP engineers to optimize the design, and their technical expertise has been invaluable in this process. They’ve always fought hard to provide the best possible product given the budget constraints that we’ve dealt with on all of our projects, and we really appreciate their help. We look forward to partnering with them on our future projects, and we encourage you to consider them for your next project.”
