We’ve been providing local, professional air conditioning and heating services to Corpus Christi, Portland and surrounding areas since 1984. At One Hour Air Conditioning & Heating®, we love what we do and take pride in helping our neighbors feel comfortable in their homes all year long.

Hi I’m Mark Wendland, General Manager of One Hour Air Conditioning & Heating.

Here in Corpus, we understand the values of hard work, honesty and serving others. As a Corpus Christi native, as well as past President of the local Rotary Club and previous Commissioner on the City of Portland Planning & Zoning Committee, I’ve seen first-hand how our community works together through the good times and the difficult times. 

These are the same values we live by here at One Hour Air Conditioning & Heating. We work together to serve you through the good times – such as building a new home and installing your entire home comfort system – and the difficult times – when your AC system suddenly stops working in the heat of summer or worst of all, if your home is impacted by a natural disaster. 

We understand these times can be stressful both financially and emotionally. So it’s our top priority to making your experience working with us as pleasant as possible. We’ll do everything in our power to make you happy and leave your home better than we found it.

Regardless of who you choose to work on your home comfort system, it’s important to protect yourself from poor quality service. Ensure you use a company that is licensed and insured.  Make sure you can feel happy and confident in your investment. 

If you have any questions at all, feel free to give me a call. Holler If you see me around town!

Mark Wendland

Helping those who need it most

As the first home services partner of Children's Miracle Network, One Hour Air Conditioning & Heating is working to help children in local hospitals. Just as we strive to provide comfort and service to our customers, we are excited to extend that goal toward patients served at children's hospitals in Corpus Christi and beyond. Driscoll Children's Hospital is a part of the Children's Miracle Network, and we're thrilled to support the children and families treated by this hospital, right here in our own backyard.

Every dollar we raise, with your help, will go to support research and training, purchase equipment, and pay for the care of every child who needs treatment. More importantly, all money raised in the area will stay right here in the community and benefit the children at Driscoll Children's Hospital. Call us to learn more.
