Great mechanical knowledge and customer service

Extreme One Hour is our go-to company for A/C services because we haven't found anywhere near us with as good customer service with value. Michael, specifically, is our requested tech. He provides a lot of background knowledge that we wouldn't be aware of and we trust his recommendations and because he's straight forward about what's really needed. It's nice not feeling like a car salesman walked into our living room to sell us a bunch of things we don't need. I appreciate interesting that Extreme One Hour is truly looking out for our best interests.

Professional service and honest answers

Our tech, Michael Treadway, did a great job repairing our blower unit. He was able to quickly diagnose the problem and give honest recommendations about how to proceed. He explained the pros and cons of all of our options and helped us get set up with the best motor for our homesize. I have recommended One Hour Service to all of my coworkers who have had AC/Heat issues and any time I need service in the future I will request Mr Treadway come out. Its refreshing to have a someone who knows what they are talking about and gives straight answers and not just trying to sell the most expensive equipment.

Knowledgeable Techs

Since my HVAC system was installed by Extreme One Hour Htg & AC, I have taken advantage of their spring and fall system checks, and just had my ducts cleaned out. Service has been prompt, professional and always pleasant. When I schedule a service call, I know it will be done correctly, and the cost is very reasonable.
