HSI Formally Hydronic Systems

From pumps and condensing boilers to chillers and custom air-handling units, we represent high-quality manufacturers that produce HVAC systems and equipment using the most current technology. Continued quality service and aftermarket product sales, delivered in a timely manner, and keeping our client-centered relationships focused on solutions long after the initial installation. That is the key to success for the clients we serve. HSI Comfort was established in 1997, by David "Mark" Boozer, and today relies on the expertise of three generations of HVAC professionals to deliver quality solutions to engineers, contractors, and end users.

It is the mission of HSI Comfort to educate the customer on all aspects of the equipment, products, and services we represent and provide a level of support in installation, preventative maintenance, and service that is unparalleled in Oklahoma and Northwest Arkansas. Our success is based on cultivating and growing solid relationships with our clients. We maintain a mutual respect with our clients based upon their needs, the needs of their clients and the desire of all to deliver quality solutions for the functionality demanded of HVAC systems in providing comfortable environments to the end users.
