Our team of HVAC experts is here to answer all of your questions and help you get started on your journey to a more comfortable, energy efficient, and eco-friendly home with geothermal energy.

If your existing air conditioner needs to be replaced or if you’re building a new home and need AC installation, we can help. We offer a wide range of air conditioners and heat pumps from Lennox, as well as ductless mini-splits from Mitsubishi and geothermal heat pumps.

We’ll help you decide which option is right for your home, your needs, and your budget. It’s always important to remember that there are many rebate and financing options you can take advantage of when replacing or installing a new air conditioning system.

Our team of experts has experience repairing and maintaining all types of air conditioning systems, so if your AC needs fixing or service, you can count on us.

With proper maintenance, we can help you extend the life of your air conditioner so you stay cool and comfortable while avoiding premature replacement costs. The benefits of regular AC maintenance include:

      • Comfort even on the hottest days
      • Increased efficiency so you don’t end up paying more than you have to for air conditioning your home
      • Peace of mind when you extend the life of your system and don’t have to pay for costly repairs

If your air conditioner does break down, we’ll repair it so that you don’t have to spend a minute more than you have to without air conditioning.

Although installing a geothermal heat pump HVAC system for your home consists of an upfront investment, it is one that is quickly returned with all of the benefits that geothermal energy provides.


Air conditioning and heating with renewable energy means that you’re not relying on fuels such as oil or natural gas. All your system will require is some electricity and the free geothermal energy located underneath your property. Each month you’ll only pay a small fee for your home’s heating and cooling needs compared to what you were previously paying. In fact, a geothermal HVAC system can reduce your energy costs by up to 80% each year!


Since your home will require much less energy, you’ll not only save on your bills every month, but also reduce your home’s impact on the environment. Air pollution from carbon emissions will be reduced, helping you preserve the planet.

Your geothermal heat pump installation can be even more affordable thanks to local utility rebates that are helping to make geothermal a popular HVAC option here in the greater Duncan and Chickasha region. In addition, you can finance your geothermal installation.

If you’re concerned about high air conditioning and heating costs, as well as your comfort and impact on the environment, a geothermal heat pump may be right for your home. The HVAC experts at DeHart Air Conditioning specialize in geothermal installation, helping you take advantage of all the benefits.

DeHart can work with architects, engineers, and contractors to help develop quality, well-performing geothermal HVAC systems. Our consulting services include:


Is your home or business building in the right location for geothermal heat pump installation? DeHart weighs unique factors like overburden, bedrock, and the presence of joints or fractures into our recommendations for your potential geothermal project that will help you maximize your savings.


TC testing, or conductivity testing, is a useful way to evaluate the geothermal potential of the property your building is on. Boring a test well is particularly important for larger buildings, and our testing will ensure less risk to you and a better engineered final system.


The size and design of a geothermal HVAC system are largely dependent not only on the ground where the loop will be installed (and how large the loop needs to be) but the heat load or heat demand that your system will have to produce to keep you comfortable. DeHart uses rigorous data collecting and cutting-edge software to ensure your system is well designed.


Need an outside opinion on your current geothermal heat pump system, or one that’s about to be installed? DeHart can review everything from schematics to existing systems themselves and give you honest feedback so you can make an informed decision about your heating and cooling.
