Our Staff

Aaron Childress: General Manager

AaronChildressI am a 2nd generation AC man and have spent 17 years in the HVAC industry here in Houston. I started in this business as an installation helper, then progressed to running service as a diagnostic technician, and a role in the purchasing side of the business. My experience also includes managing my family's A/C Company for 6 years. Since I have served in all aspects of this business, it has enabled me to learn a tremendous amount about our trade and the people that we service. I would like to think my dedication to customer service and high level of integrity is why I am in the position I am today. Here at One Hour, we want that same mindset to come through in our service to all of our customers. We will always do what is right for the customer at any cost and have the best guarantees I have ever seen in the industry. I am proud to work here at One Hour and I am prepared to do whatever it takes to prove that we are the best company around and deserve to have your business.

I have been married for 10 years to my wonderful wife Cheree and I have two great children.
