At DeHart Air Conditioning, we strive to make HVAC upgrades even more affordable for homeowners near Chickasha and Duncan, Oklahoma. Because we work primarily with high-quality heating and cooling equipment from Lennox, we are able to offer our customers special discounts directly from Lennox.
In addition to our promotions, we work with local utility companies to help our customers take advantage of special rebates when they upgrade their HVAC equipment or install a geothermal system. Learn more about our current offers below and through our Financing & Rebates page!
FREE UV LIGHT WITH EVERY INSTALL
With every heating and cooling system installation, we’ll add in a FREE in-duct UV light, which can help purify and sanitize the air passing through your system.
5 YEAR LABOR WARRANTY ON LENNOX AND CLIMATEMASTER
Every new Lennox or ClimateMaster heating and cooling system includes a 5 year labor warranty!
26% TAX CREDIT ON GEOTHERMAL (Extended!)
Qualify for a federal tax credit equal to 26% off the installation costs of a geothermal system through the end of 2022. This tax credit will drop to 22% in 2023 so now is the time to take advantage of maximum savings!
Local Chickasha and Duncan utility rebates can help lower the cost of energy-efficiency upgrades to your home even more! Reach out to DeHart today to find out what utility rebates are available for customers of OG&E, OEC, CKenergy Electric Cooperative, Centerpoint Energy, Cotton Electric, Red River Valley Rural Electric Association, Rural Electric Cooperative, PSO, and Duncan Power.

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.
