About us

We are HSI Comfort -
HVAC Manufacturers' Representative

HSI Comfort is the supplier of choice for heating, ventilation, air conditioning systems, and equipment for engineers, contractors, and building maintenance crews.

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. 

Our History


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. With nearly 60 years of experience in the industry, the Boozer family capitalizes on the knowledge learned from the very manufacturers who taught them the business while representing their products throughout Oklahoma and Northwest Arkansas. 

Through the years, the client relationships that HSI Comfort has cultivated with engineers and contractors has led the company to become known as the first choice in HVAC solutions on projects such as Norman Regional Moore, Freedom Elementary at Fort Sill, and Oklahoma State University Central Plant.
