A FAMILY-OWNED HVAC COMPANY WITH 100 YEARS OF EXPERIENCE
DeHart was founded in 1920 in Chickasha, OK, by Ed DeHart. In the early years of the company, which was first called DeHart Sheet Metal Works, DeHart was the first automated sheet metal fabrication shop in the Southwestern United States.
Ed’s son Elmer joined his father’s business in 1949, which was renamed DeHart Air Conditioning and Electronics to focus on the HVAC industry. In 1965, a new building for the company was built, which has remained as DeHart’s Chickasha location ever since. Elmer’s son Mark joined the family business in 1976, and expanded the company into the commercial and geothermal markets. Today, Mark’s sons, Seth and John, are co-owners, and have grown the company to include a second location in Duncan, OK.

HIGH-QUALITY DIVERSE HVAC SERVICES
Whether you’re a homeowner that needs help with your air conditioning and heating system (even unique solutions like geothermal systems, VRFs, gas log fireplaces, and radiant floor heating), your ductwork, or with your indoor air quality, we can help.
From services ranging from replacement, repair, and maintenance to new construction HVAC installation, our expert technicians do it all. We even install portable generators and home generators, both from Kohler, to guarantee your power will stay on. We’ll make your home more comfortable regardless of what the weather outside is like and help to keep you and your family healthy with solutions like air filtration, purification, and humidity control.
We’re just as comfortable doing new home construction HVAC as we are installing, maintaining, and even educating the customer on new HVAC technologies like ductless mini split heat pumps from Mitsubishi Electric.
At DeHart, we also offer commercial HVAC solutions so property and business owners from Chickasha to Duncan and the surrounding area can keep their properties comfortable year-round, including commercial HVAC replacement and new commercial HVAC ductwork and design.
