HVAC & Plumbing Construction and Contracting

HVAC Service

H&G specializes in commercial, institutional and industrial installations. We are qualified to handle a variety of design-build and design-assist mechanical projects. Approximately two-thirds of H&G’s volume is comprised of complex, negotiated contracts with an accelerated schedule.

Our History

H&G Air Conditioning & Heating was founded in 1968. Upon adding the electrical contracting division in 1983, the corporate name was changed to H&G Systems to more accurately reflect business diversification. From day one, H&G’s core values have been built around the spirit of trust and respect. The company’s diversification has attracted clients who desire a collaborative approach to their projects. While we remain client focused, we are also committed to sustaining solid supplier and subcontractor (peer) relationships. As of 2015, Grant Yaney assumed the lead role in company ownership. Grant is a graduate of Purdue University, with a degree in Mechanical Engineering. Not only does Grant hold licenses in the State of Texas as a professional engineer (P.E.) and as a mechanical contractor, but he is also a LEED accredited professional (LEED AP), and a certified energy manager (CEM – by the Association of Energy Engineers). Grant understands that success starts with Leadership.

Our Specialty

H&G specializes in commercial, institutional and industrial installations. We are qualified to handle a variety of design-build and design-assist mechanical projects. Approximately two-thirds of H&G’s volume is comprised of complex, negotiated contracts with an accelerated schedule. Every member of our team is committed to Project Quality.

Our Experience

Our experience in various types of construction, such as data and communication centers, office buildings, hotels, churches, historical renovations, industrial food plants, manufacturing facilities and laboratories enables our customers to trust in our ability to perform with excellence in a timely manner. The needs of a project and its fast-track schedule demand a group of professionals who not only bring their expertise to the project, but also blend their skills with those of other project team members to form one cohesive working unit. Our mechanical (HVAC and plumbing) expertise provides our clients with the assurance that they will receive a coordinated project, from the point of conceptual design until our clients are handed the keys. Our team of seasoned experts are ready to build your next project on Time and on Budget.

Emergency Services

Our in-house service department is staffed with qualified plumbing and HVAC technicians who provide emergency service as well as routine maintenance, electronic monitoring and building/energy management and service agreements. We take care of our customers 24-7, Day or Night.

We gratefully acknowledge the support of all of the H&G Systems employees who have worked so diligently since 1968 to demonstrate that Quality & Service are the cornerstones of our successful business.

Ken Smith with Blum Consulting Engineers

“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.”

J. Scott Clendenin with EMA Engineering and Consulting, Inc.

“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.”

Warren Andres, Wade Andres and Wayne Wilson with ANDRES Construction

“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.”
