Knowing who you can trust your comfort to can be a tough decision. Fortunately, if your home or business needs air conditioning, heating, or indoor air quality services, the local experts at DeHart Air Conditioning are just a phone call away.

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.

As of 2020, DeHart Air Conditioning has 100 years of experience in the business. As a fourth-generation family-owned HVAC company and a full service dealership of more than 25 employees, we know the Chickasha and Duncan area and what homeowners and commercial property owners in the region need.

That’s why our caring team of expert HVAC professionals will make sure you stay cool during the summer heat and cozy during the winter.

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.

What our customers are saying

I would like to commend DeHart Air Conditioning and two of your employees, Stacy and Akeem. When we moved into our house two years ago we had DeHart clean the ducts.
